This covers the case of alignment stringency being increased without lowering the starting offset, unlike the previous changes, and even more elegantly than those. * target.c (ffetarget_align): Make sure alignments are non-zero, just in case. Mon Jun 29 09:47:33 1998 Craig Burley Fix 980628-*.f: * bld.h: New `pad' field and accessor macros for ACCTER, ARRTER, and CONTER ops. * bld.c (ffebld_new_accter, ffebld_new_arrter, ffebld_new_conter_with_orig): Initialize `pad' field to zero. * com.c (ffecom_transform_common_): Include initial padding (aka modulo aka offset) in size calculation. Copy initial padding value into FFE initialization expression so the GBE transformation of that expression includes it. Make array low bound 0 instead of 1, for consistency. (ffecom_transform_equiv_): Include initial padding (aka modulo aka offset) in size calculation. Copy initial padding value into FFE initialization expression so the GBE transformation of that expression includes it. Make array low bound 0 instead of 1, for consistency. (ffecom_expr_, case FFEBLD_opACCTER): Delete unused `size' variable. Track destination offset separately, allowing for initial padding. Don't bother setting initial PURPOSE offset if zero. Include initial padding in size calculation. (ffecom_expr_, case FFEBLD_opARRTER): Allow for initial padding. Include initial padding in size calculation. Make array low bound 0 instead of 1, for consistency. (ffecom_finish_global_): Make array low bound 0 instead of 1, for consistency. (ffecom_notify_init_storage): Copy `pad' field from old ACCTER to new ARRTER. (ffecom_notify_init_symbol): Ditto. * data.c (ffedata_gather_): Initialize `pad' field in new ARRTER to 0.

If new padding larger than old, update old. (ffeglobal_save_common): Use correct type for size throughout. * global.h: Use correct type for size throughout. (ffeglobal_common_pad): New macro. (ffeglobal_pad): Delete this unused and broken macro. Sat Jun 27 12:18:33 1998 Jeffrey A Law (law@cygnus.com) * Make-lang.in (g77): Depend on mkstemp.o. Link in mkstemp.o.

Mon Jun 15 23:39:24 1998 Craig Burley * Make-lang.in (f/g77.info): Use -f when removing pre-existing Info files, if any. (This rm command can go away once makeinfo has been changed to delete .info-N files beyond the last one it creates.) * Make-lang.in ($(srcdir)/f/intdoc.texi): Compile using $(INCLUDES) macro to get the new hconfig.h and system.h headers.

(g77$(exeext)): Depend on and link in g77version.o. * g77spec.c: Rewrite to be more like 0.5.22 version of g77.c, making filtering of command line smarter so mixed Fortran and C (etc.) can be compiled, verbose version info can be obtained, etc. * lang-specs.h (f77-version): New "language" to support "g77 -v" command under new gcc 2.8 regime. * lex.c (ffelex_file_fixed): If -fnull-version, just substitute a "source file" that prints out version info. * top.c, top.h: Support -fnull-version. * lang-specs.h: Use "%O" instead of OO macro to specify object extension. Remove old stringizing cruft. * Make-lang.in (g77.c, g77spec.o, g77.o, g77$(exeext), g77-cross$(exeext), f771, $(srcdir)/f/g77.info, $(srcdir)/f/g77.dvi, $(srcdir)/f/intdoc.texi, f77.install-common, f77.install-info, f77.install-man, f77.uninstall, $(G77STAGESTUFF), f77.stage1, f77.stage2, f77.stage3, f77.stage4, f77.distdir): Don't do anything unless user specified "f77" or "F77" in $LANGUAGES either during configuration or explicitly. For convenience of various tests and to work around lack of the assignment "LANGUAGES=$(BOOT_LANGUAGES)" in the "make stage1" command of "make bootstrap" in gcc, use a touch file named "lang-f77" to communicate whether this is the case. * Make-lang.in (F77_FLAGS_TO_PASS): Delete this macro, replace with minimal expansion of its former self in each of the two instances where it was used. * Makefile.in (HOST_CC): Delete this definition. * com.c (index, rindex): Delete these declarations. * proj.h: (isascii): Delete this. * Make-lang.in (f77.install-common): Warn if `f77-install-ok' flag-file exists, since it no longer triggers any activity. Rename libf2c.a and f2c.h to libg2c.a and g2c.h, normalize and simplify g77/libg2c build process: * Make-lang.in: Remove all support for overwriting /usr/bin/f77 etc., or whatever the actual names are via $(prefix) and $(local_prefix). (g++ overwrites /usr/bin/c++, but then it's often the only C++ compiler on the system; f77 often exists on systems that are installing g77.) (f77.realclean): Remove obsolete target. (g77.c, g77$(exeext)): Minor changes to look more like g++'s stuff. (f771): Now built with srcdir=gcc/f, not srcdir=gcc, to be more like g++ and such. (f/Makefile): Removed, as g++ doesn't need this rule. (f77.install-common): No longer install f77, etc. (f77.install-man): No longer install f77.1. (f77.uninstall): No longer uninstall f77, f77.1, etc. (f77.stage1, f77.stage2, f77.stage3, f77.stage4): Do work only if "f77" appears in $(LANGUAGES). (Note: gcc's Makefile.in's bootstrap target should set LANGUAGES=$(BOOT_LANGUAGES) when making the stage1 target.) * Makefile.in: Update vis-a-vis gcc/cp/Makefile.in. (none): Remove. (g77-only): Relocate. (all.indirect, f771, *.o): Now assumes current directory is this dir (gcc/f), not the parent directory. (TAGS): Remove "echo 'parse.y,0' >> TAGS ;" line. * config-lang.in: Delete commented-out code. Fix stagestuff definition. Add more stuff to diff_excludes definition. Don't create any directories. Set outputs to f/Makefile, to get variable substition to happen (what does that really do, anyway?!). * g77spec.c: Rename libf2c to libg2c. * com.h: Remove all of the gcc back-end decls, since egcs should have all of them correct. * com.c: Include "proj.h" before anything else, as that's how things are supposed to work. * ste.c: Ditto. * bad.c: Include "flags.j" here, since some diagnostics check flag_pedantic_errors. * Makefile.in (f/*.o): Rebuild dependencies via deps-kinda. * output.j: New source file. * Make-lang.in (F77_SRCS): Update accordingly. * Makefile.in (OUTPUT_H): Ditto. (deps-kinda): Ditto. * com.c: Include "output.j" here. * lex.c: Ditto. Mon May 25 03:34:42 1998 Craig Burley * com.c (ffecom_expr_): Fix D**I and Z**I cases to not convert (DOUBLE PRECISION) D and (DOUBLE COMPLEX) Z to INTEGER. (This is dead code here anyway.) Sat May 23 06:32:52 1998 Craig Burley * com.c (ffecom_finish_symbol_transform_): Don't transform statement (nested) functions, to avoid gcc compiling them and thus producing linker errors if they refer to undefined external functions. But warn if they're unused and -Wunused. * bad.def (FFEBAD_SFUNC_UNUSED): New diagnostic. Wed May 20 12:12:55 1998 Craig Burley * Version 0.5.23 released. Tue May 19 14:52:41 1998 Craig Burley * bad.def (FFEBAD_OPEN_UNSUPPORTED, FFEBAD_INQUIRE_UNSUPPORTED, FFEBAD_READ_UNSUPPORTED, FFEBAD_WRITE_UNSUPPORTED, FFEBAD_QUAD_UNSUPPORTED, FFEBAD_BLOCKDATA_STMT, FFEBAD_TRUNCATING_CHARACTER, FFEBAD_TRUNCATING_HOLLERITH, FFEBAD_TRUNCATING_NUMERIC, FFEBAD_TRUNCATING_TYPELESS, FFEBAD_TYPELESS_OVERFLOW): Change these from warnings to errors.

Fri May 15 10:52:49 1998 Craig Burley * com.c (ffecom_convert_narrow_, ffecom_convert_widen_): Be even more persnickety in checking for internal bugs. Also, if precision isn't changing, just return the expr. * expr.c (ffeexpr_token_number_): Call ffeexpr_make_float_const_ to make an integer. (ffeexpr_make_float_const_): Handle making an integer. * intrin.c (ffeintrin_init_0): Distinguish between crashes on bad arg base and kind types.

Tue Apr 28 09:23:10 1998 Craig Burley Fix 980427-0.f: * global.c (ffeglobal_ref_progunit_): When transitioning from EXT to FUNC, discard hook, since the decl, if any, is probably wrong. Sun Apr 26 09:05:50 1998 Craig Burley * com.c (ffecom_char_enhance_arg_): Wrap the upper bound (the PARM_DECL specifying the length of the CHARACTER*(*) dummy arg) in a variable_size invocation, to prevent dwarf2out.c crashing when compiling code with -g. Sat Apr 18 15:26:57 1998 Jim Wilson * g77spec.c (lang_specific_driver): New argument in_added_libraries. New local added_libraries. Increment count when add library to arglist. Sat Apr 18 05:03:21 1998 Craig Burley * com.c (ffecom_check_size_overflow_): Ignore overflow as well if dummy argument. Fri Apr 17 17:18:04 1998 Craig Burley * version.h: Get rid of the overly large headers here too, as done in version.c. Tue Apr 14 15:51:37 1998 Dave Brolley * com.c (init_parse): Now returns char* containing filename; Tue Apr 14 14:40:40 1998 Craig Burley * com.c (ffecom_start_progunit_): Mark function decl as used, to avoid spurious warning (-Wunused) for ENTRY. Tue Apr 14 14:19:34 1998 Craig Burley * sta.c (ffesta_second_): Check for CASE DEFAULT as well as CASE, or it won't be recognized. Thu Apr 9 00:18:44 1998 Dave Brolley (brolley@cygnus.com) * com.c (finput): New variable. (init_parse): Handle !USE_CPPLIB. (finish_parse): New function. (lang_init): No longer declare finput. Sat Apr 4 17:45:01 1998 Richard Henderson * com.c (ffecom_expr_): Revert Oct 22 change. Instead take a WIDENP argument so that we can respect the signedness of the original type. (ffecom_init_0): Do sizetype initialization first. 1998-03-28 Dave Love * Make-lang.in (f771$(exeext)): Fix typo. 1998-03-24 Martin von Loewis * com.c (lang_print_xnode): New function. Mon Mar 23 21:20:35 1998 Craig Burley * version.c: Reduce to a one-line file, like gcc's version.c, since there's really no content there.

Do appropriate cleanups. Explain. (f77.mostlyclean): Add f/ansify and f/intdoc.h0 to cleanups. * f/ansify.c: New program. * f/intdoc.c: Fix so it conforms to ANSI C. #include f/intdoc.h0 instead of f/intdoc.h. Avoid some warnings. * f/intdoc.h, f/intdoc.in: Rename the former to the latter; no changes made to the content in this patch! * f/intrin.h (ffeintrinFamily): Fix to conform to ANSI C.

Fix 970813-0.f: * com-rt.def (FFECOM_gfrtALARM): Returns `integer', not `void'. Mon Aug 18 09:01:54 1997 Jeffrey A Law (law@cygnus.com) * Makefile.in (F77_OBJS): Re-alphabetize. * Make-lang.in (F77_SRCS): Likewise.

Sat Aug 16 19:41:33 1997 Craig Burley * com.c (ffecom_make_gfrt_): For rttypeREAL_F2C_, return double_type_node; for rttypeREAL_GNU_, return _real_type_node. 1997-08-13 Dave Love * config-lang.in (diff_excludes): Add some hints about known problematic platforms. 1997-08-13 Dave Love * intdoc.h: Document `alarm'. Tue Aug 12 10:23:02 1997 Jeffrey A Law (law@cygnus.com) * config-lang.in: Don't demand the backend patch. * com.c (lang_printable_name): Second argument is now an int.

Mon Aug 11 01:52:03 1997 Craig Burley * com.c (ffecom_build_complex_constant_): Go with the new build_complex() approach used in gcc-2.8. * com.c (ffecom_sym_transform_): Don't set DECL_IN_SYSTEM_HEADER for a tree node that isn't a VAR_DECL, which happens when var is in common! * com.c (ffecom_expr_intrinsic_) (case FFEINTRIN_impALARM): No need to test codegen_imp -- there's only one valid here. * intrin.def (FFEINTRIN_impALARM): Specify `Status' argument as write-only. Fri Aug 8 05:40:23 1997 Craig Burley Substantial changes to accommodate distinctions among run-time routines that support intrinsics, and between routines that compute and return the same type vs. those that compute one type and return another (or `void'): * com-rt.def: Specify new return type REAL_F2C_ instead of many DOUBLE_, COMPLEX_F2C_ instead of COMPLEX_, and so on. Clear up the *BES* routines "once and for all". * com.c: New return types.

(ffecom_char_args_): Use new ffeintrin_gfrt_direct() routine. (ffecom_expr_intrinsic_): Simplify how run-time routine is selected (via `gfrt' only now; lose the redundant `ix' variable). Eliminate the `library' label; any code that doesn't return directly just `break's out now with `gfrt' set appropriately. Set `gfrt' to default choice initially, either a fast direct form or, if not available, a slower indirect-callable form. (ffecom_make_gfrt_): No longer need to do special check for complex; it's built into the new return-type regime. (ffecom_ptr_to_expr): Use new ffeintrin_gfrt_indirect() routine. * intrin.c, intrin.h: `gfrt' field replaced with three fields, so it is easier to provide faster direct-callable and GNU-convention indirect-callable routines in the future. DEFIMP macro adjusted accordingly, along with all its uses. (ffeintrin_gfrt_direct): New function. (ffeintrin_gfrt_indirect): Ditto. (ffeintrin_is_actualarg): If `-fno-f2c' is in effect, require a GNU-callable version of intrinsic instead of an f2c-callable version, so indirect calling is still checked. * intrin.def: Replace one GFRT field with the three new fields, as appropriate for each DEFIMP intrinsic. * com.c (ffecom_stabilize_aggregate_, ffecom_convert_to_complex_): Make these `static'. Thu Aug 7 11:24:34 1997 Craig Burley Provide means for front end to determine actual "standard" return type for an intrinsic if it is passed as an actual argument: * com.h, com.c (ffecom_gfrt_basictype, ffecom_gfrt_kindtype): New functions. (ffecom_gfrt_kind_type_): Replaced with new function. All callers updated. (ffecom_make_gfrt_): No longer need do anything with kind type. * intrin.c (ffeintrin_basictype, ffeintrin_kindtype): Now returns correct type info for specific intrinsic (based on type of run-time-library implementation). Wed Aug 6 23:08:46 1997 Craig Burley * global.c (ffeglobal_ref_progunit_): Don't reset number of arguments just due to new type info, so useful warnings can be issued. 1997-08-06 Dave Love * intrin.def: Fix IDATE_vxt argument order. * intdoc.h: Likewise. Thu Jul 31 22:22:03 1997 Craig Burley * global.c (ffeglobal_proc_ref_arg): If REF/DESCR disagreement, DESCR is CHARACTER, and types disagree, pretend the argsummary agrees so the message ends up being about type disagreement. (ffeglobal_proc_def_arg): Ditto. * expr.c (ffeexpr_token_first_rhs_3_): Set info for LABTOK to NONE of everything, to avoid misdiagnosing filewide usage of alternate returns. Sun Jul 20 23:07:47 1997 Craig Burley * com.c (ffecom_sym_transform_): If type gets set to error_mark_node, just return that for transformed symbol. (ffecom_member_phase2_): If type gets set to error_mark_node, just return. (ffecom_check_size_overflow_): Add `dummy' argument to flag that type is for a dummy, update all callers. Sun Jul 13 17:40:53 1997 Craig Burley Fix 970712-1.f: * where.c (ffewhere_set_from_track): If start point is too large, just use initial start point. 0.6 should fix all this properly. Fix 970712-2.f: * com.c (ffecom_sym_transform_): Preserve error_mark_node for type. (ffecom_type_localvar_): Ditto. (ffecom_sym_transform_): If type is error_mark_node, don't error-check decl size, because back end responds by setting that to an integer 0 instead of error_mark_node. (ffecom_transform_common_): Same as earlier fix to _transform_ in that size is checked by dividing BITS_PER_UNIT instead of multiplying. (ffecom_transform_equiv_): Ditto. Fix 970712-3.f: * stb.c (ffestb_R10014_): Fix flaky fall-through in error test for FFELEX_typeCONCAT by just replicating the code, and do FFELEX_typeCOLONCOLON while at it. 1997-07-07 Dave Love * intdoc.h: Add various missing pieces; correct GMTIME, LTIME result ordering. * intrin.def, com-rt.def: Add alarm. * com.c (ffecom_expr_intrinsic_): Add case for alarm. Thu Jun 26 04:19:40 1997 Craig Burley Fix 970302-3.f: * com.c (ffecom_sym_transform_): For sanity-check compare of gbe size of local variable to g77 expectation, use varasm.c/assemble_variable technique of dividing BITS_PER_UNIT out of gbe info instead of multiplying g77 info up, to avoid crash when size in bytes is very large, and overflows an `int' or similar when multiplied. Fix 970626-2.f: * com.c (ffecom_finish_symbol_transform_): Don't bother transforming a dummy argument, to avoid a crash. * ste.c (ffeste_R1227): Don't return a value if the result decl, or its type, is error_mark_node. Fix 970626-4.f: * lex.c (ffelex_splice_tokens): `-fdollar-ok' is irrelevant to whether a DOLLAR token should be made from an initial character of `$'. Fix 970626-6.f: * stb.c (ffestb_do3_): DO iteration variable is an lhs, not rhs, expression. Fix 970626-7.f and 970626-8.f: * expr.c (ffeexpr_cb_comma_i_1_): Set IMPDO expression to have clean info, because undefined rank, for example, caused crash on mangled source on UltraSPARC but not on Alpha for a series of weird reasons. (ffeexpr_cb_close_paren_): If not CLOSE_PAREN, push opANY expression onto stack instead of attempting to mimic what program might have wanted. (ffeexpr_cb_close_paren_): Don't wrap opPAREN around opIMPDO, just warn that it's gratuitous. * bad.def (FFEBAD_IMPDO_PAREN): New warning. Fix 970626-9.f: * expr.c (ffeexpr_declare_parenthesized_): Must shut down parsing in kindANY case, otherwise the parsing engine might decide there's an ambiguity. (ffeexpr_token_name_rhs_): Eliminate parentypeSUBROUTINE_ case, so we crash right away if it comes through. * st.c, st.h, sta.c, sta.h (ffest_shutdown, ffesta_shutdown): New functions. Tue Jun 24 19:47:29 1997 Craig Burley * com.c (ffecom_check_size_overflow_): New function catches some cases of the size of a type getting too large. varasm.c must catch the rest. (ffecom_sym_transform_): Use new function. (ffecom_type_localvar_): Ditto. Mon Jun 23 01:09:28 1997 Craig Burley * global.c (ffeglobal_proc_def_arg): Fix comparison of argno to #args. (ffeglobal_proc_ref_arg): Ditto. * lang-options.h, top.c: Rename `-fdebug' to `-fxyzzy', since it's an unsupported internals option and some poor user might guess that it does something. * bad.def: Make a warning for each filewide diagnostic. Put all filewides together. * com.c (ffecom_sym_transform_): Don't substitute known global tree for global entities when `-fno-globals'. * global.c (ffeglobal_new_progunit_): Don't produce fatal diagnostics about globals when `-fno-globals'. Instead, produce equivalent warning when `-Wglobals'. (ffeglobal_proc_ref_arg): Ditto. (ffeglobal_proc_ref_nargs): Ditto. (ffeglobal_ref_progunit_): Ditto. * lang-options.h, top.c, top.h: New `-fno-globals' option. Sat Jun 21 12:32:54 1997 Craig Burley * expr.c (ffeexpr_fulfill_call_): Set array variable to avoid warning about uninitialized variable. * Make-lang.in: Get rid of any setting of HOST_* macros, since these will break gcc's build! * makefile: New file to make building derived files easier. Thu Jun 19 18:19:28 1997 Craig Burley * g77.c (main): Install Emilio Lopes' patch to support Ratfor, and to fix the printing of the version string to go to stderr, not stdout. * lang-specs.h: Install Emilio Lopes' patch to support Ratfor, and patch the result to support picking up `*f771' from the `specs' file. Thu Jun 12 14:36:25 1997 Craig Burley * storag.c (ffestorag_update_init, ffestorag_update_save): Also update parent, in case equivalence processing has already eliminated pointers to it via the local equivalence info. Tue Jun 10 14:08:26 1997 Craig Burley * intdoc.c: Add cross-reference to end of description of any generic intrinsic pointing to other intrinsics with the same name. Warn about explicit type declaration for intrinsic that disagrees with invocation: * expr.c (ffeexpr_paren_rhs_let_): Preserve type info for intrinsic functions. (ffeexpr_token_funsubstr_): Ditto. * intrin.c (ffeintrin_fulfill_generic): Warn if type info of fulfilled intrinsic invocation disagrees with explicit type info given symbol. (ffeintrin_fulfill_specific): Ditto. * stc.c (ffestc_R1208_item): Preserve type info for intrinsics. (ffestc_R501_item): Ditto. Mon Jun 9 17:45:44 1997 Craig Burley * com.c (ffecom_expr_intrinsic_): Fix several of the libU77/libF77-unix handlers to properly convert their arguments. * com-rt.def (FFECOM_gfrtFSTAT): Append missing "i" to arg string. Fri Jun 6 14:37:30 1997 Craig Burley * com.c (ffecom_expr_intrinsic_): Have a case statement for every intrinsic implementation, so missing ones are caught via gcc warnings. Don't call ffeintrin_codegen_imp anymore. * intrin.c (ffeintrin_fulfill_generic): Remove cg_imp stuff from here. (ffeintrin_codegen_imp): Delete this function. * intrin.def, intrin.h: Remove DEFIMQ stuff from here as well. Thu Jun 5 13:03:07 1997 Craig Burley * top.c (ffe_decode_option): New -fbadu77-intrinsics-* options. * top.h: Ditto. * intrin.h: New BADU77 family. * intrin.c (ffeintrin_state_family): Ditto. Implement new scheme to track intrinsic names vs. forms: * intrin.c (ffeintrin_fulfill_generic), (ffeintrin_fulfill_specific), (ffeintrin_is_intrinsic), intrin.def: The documented name is now either in the generic info or, if no generic, in the specific info. For a generic, the specific info contains merely the distinguishing form (usually "function" or "subroutine"), used for diagnostics about ambiguous references and in the documentation. * intrin.def: Clean up formatting of DEFNAME block. Convert many libU77 intrinsics into generics that support both subroutine and function forms. Put the function forms of side-effect routines into the new BADU77 family. Make MCLOCK and TIME return INTEGER*4 again, and add INTEGER*8 equivalents called MCLOCK8 and TIME8. Fix up more status return values to be written and insist on them being I1 as well. * com.c (ffecom_expr_intrinsic_): Lots of changes to support new libU77 intrinsic interfaces. Mon Jun 2 00:37:53 1997 Craig Burley * com.c (ffecom_init_0): Pointer type is now INTEGER(KIND=7), not INTEGER(KIND=0), since we want to reserve KIND=0 for future use. Thu May 29 14:30:33 1997 Craig Burley Fix bugs preventing CTIME(I*4) from working correctly: * com.c (ffecom_char_args_): For FUNCREF case, process args to intrinsic just as they would be in ffecom_expr_intrinsic_. * com-rt.def (FFECOM_gfrtCTIME, FFECOM_gfrtTTYNAM): Fix argument decls to specify `&'. Wed May 28 22:19:49 1997 Craig Burley Fix gratuitous warnings exposed by dophot aka 970528-1: * global.c (ffeglobal_proc_def_arg, ffeglobal_proc_ref_arg): Support distinct function/subroutine arguments instead of just procedures. * global.h: Ditto. * expr.c (ffeexpr_fulfill_call_): A SYMTER with kindNONE also is a procedure (either function or subroutine). Mon May 26 20:25:31 1997 Craig Burley * bad.def: Have several lexer diagnostics refer to documentation for people who need more info on what Fortran source code is supposed to look like. * expr.c (ffeexpr_reduced_bool1_), bad.def: New diagnostics specific to .NOT. now mention only one operand instead of two. * g77.c: Recognize -fsyntax-only, similar to -c etc. (lookup_option): Fix bug that prevented non-`--' options from being recognized. Sun May 25 04:29:04 1997 Craig Burley * intrin.def (FFEINTRIN_impCTIME): Accept `I*' expression for STime instead of requiring `I2'. Tue May 20 16:14:40 1997 Craig Burley * symbol.c (ffesymbol_reference): All references to standard intrinsics are considered explicit, so as to avoid generating basically useless warnings. * intrin.c, intrin.h (ffeintrin_is_standard): Returns TRUE if intrinsic is standard. Sun May 18 21:14:59 1997 Craig Burley * com-rt.def: Changed all external names of the form `"\([a-z0-9]*\)_' to `"G77_\1_0"' so as to allow any name valid as an intrinsic to be used as such and as a user-defined external procedure name or common block as well. Thu May 8 13:07:10 1997 Craig Burley * expr.c (ffeexpr_cb_end_notloc_): For %VAL, %REF, and %DESCR, copy arg info into new node. Mon May 5 14:42:17 1997 Craig Burley From Uwe F. Mayer : * Make-lang.in (g77-cross): Fix typo in g77.c path. From Brian McIlwrath : * lang-specs.h: Have g77 pick up options from a section labeled `*f771' of the `specs' file. Sat May 3 02:46:08 1997 Craig Burley * intrin.def (FFEINTRIN_defSIGNAL): Add optional `Status' argument that com.c already expects (per Dave Love). More changes to support better tracking of (filewide) globals, in particular, the arguments to procedures: * bad.def (FFEBAD_FILEWIDE_NARGS, FFEBAD_FILEWIDE_NARGS_W, FFEBAD_FILEWIDE_ARG, FFEBAD_FILEWIDE_ARG_W): New diagnostics. * expr.c (ffebad_fulfill_call_): Provide info on each argument to ffeglobal. * global.c, global.h (ffeglobal_proc_def_arg, ffeglobal_proc_def_nargs, ffeglobal_proc_ref_arg, ffeglobal_proc_ref_args): New functions. (ffeglobalArgSummary, ffeglobalArgInfo_): New types. Tue Apr 29 18:35:41 1997 Craig Burley More changes to support better tracking of (filewide) globals: * expr.c (ffeexpr_fulfill_call_): New function. (ffeexpr_token_name_lhs_): Call after building procedure reference expression. Also leave info field for ANY-ized expression alone. (ffeexpr_token_arguments_): Ditto. Mon Apr 28 20:04:18 1997 Craig Burley Changes to support better tracking of (filewide) globals, mainly to avoid crashes due to inlining: * bad.def: Go back to quoting intrinsic names, (FFEBAD_FILEWIDE_DISAGREEMENT, FFEBAD_FILEWIDE_TIFF, FFEBAD_FILEWIDE_TYPE_MISMATCH): New diagnostics. (FFEBAD_INTRINSIC_EXPIMP, FFEBAD_INTRINSIC_GLOBAL): Reword for clarity. * com.c (ffecom_do_entry_, ffecom_start_progunit_, ffecom_sym_transform_): Accommodate new FFEGLOBAL_typeEXT possibility. * expr.c (ffeexpr_sym_lhs_call_, ffeexpr_sym_lhs_extfunc_, ffeexpr_sym_rhs_actualarg_, ffeexpr_declare_parenthesized_, ffeexpr_paren_rhs_let_, ffeexpr_token_funsubstr_): Fill in real kind info instead of leaving NONE where appropriate. Register references to intrinsics and globals with ffesymbol using new ffesymbol_reference function instead of ffesymbol_globalize. * global.c (ffeglobal_type_string_): New array for new diagnostics. * global.h, global.c: Replace ->init mechanism with ->tick mechanism. Move other common-related members into a substructure of a union, so the proc substructure can be introduced to include members related to externals other than commons. Don't complain about ANY-ized globals; ANY-ize globals once they're complained about, in any case where code generation could become a problem. Handle global entries that have NONE type (seen as intrinsics), EXT type (seen as EXTERNAL), and so on. Keep track of kind and type of externals, both via definition and via reference. Diagnose disagreements about kind or type of externals (such as functions). (ffeglobal_ref_intrinsic, ffeglobal_ref_progunit_): New functions. * stc.c (ffestc_R1207_item, ffestc_R1208_item, ffestc_R1219, ffestc_R1226): Call ffesymbol_reference, not ffesymbol_globalize. * stu.c (ffestu_sym_end_transition, ffestu_sym_exec_transition): Call ffesymbol_reference, not ffesymbol_globalize. * symbol.c (ffesymbol_globalize): Removed... (ffesymbol_reference): ...to this new function, which more generally registers references to symbols, globalizes globals, and calls on the ffeglobal module to check globals filewide. * global.h, global.c: Rename some macros and functions to more clearly distinguish common from other globals. All callers changed. * com.c (ffecom_sym_transform_): Trees describing filewide globals must be allocated on permanent obstack. * expr.c (ffeexpr_token_name_lhs_): Don't generate gratuitous diagnostics for FFEINFO_whereANY case. Thu Apr 17 03:27:18 1997 Craig Burley * global.c: Add support for flagging intrinsic/global confusion via warnings. * bad.def (FFEBAD_INTRINSIC_EXPIMP, FFEBAD_INTRINSIC_GLOBAL): New diagnostics. * expr.c (ffeexpr_token_funsubstr_): Ditto. (ffeexpr_sym_lhs_call_): Ditto. (ffeexpr_paren_rhs_let_): Ditto. * stc.c (ffestc_R1208_item): Ditto. Wed Apr 16 22:40:56 1997 Craig Burley * expr.c (ffeexpr_declare_parenthesized_): INCLUDE context can't be an intrinsic invocation either. Fri Mar 28 10:43:28 1997 Craig Burley * expr.c (ffeexpr_token_arguments_): Make sure top of exprstack is operand before dereferencing operand field. * lex.c (ffelex_prepare_eos_): Fill up truncated hollerith token, so crash on null ->text field doesn't happen later. * stb.c (ffestb_R10014_): If NAMES isn't recognized (or the recognized part is followed in the token by a non-digit), don't try and collect digits, as there might be more than FFEWHERE_indexMAX letters to skip past to do so -- and the code is diagnosed anyway. Thu Mar 27 00:02:48 1997 Craig Burley * com.c (ffecom_sym_transform_): Force local adjustable array onto stack. * stc.c (ffestc_R547_item_object): Don't actually put the symbol in COMMON if the symbol has already been EQUIVALENCE'd to a different COMMON area. * equiv.c (ffeequiv_add): Don't actually do anything if there's a disagreement over which COMMON area is involved. Tue Mar 25 03:35:19 1997 Craig Burley * com.c (ffecom_transform_common_): If no explicit init of COMMON area, don't actually init it even though storage area suggests it. Mon Mar 24 12:10:08 1997 Craig Burley * lex.c (ffelex_image_char_): Avoid overflowing the column counter itself, as well as the card image. * where.c (ffewhere_line_new): Cast ffelex_line_length() to (size_t) so 255 doesn't overflow to 0! * stc.c (ffestc_labeldef_notloop_begin_): Don't gratuitously terminate loop before processing statement, so block doesn't disappear out from under EXIT/CYCLE processing. (ffestc_labeldef_notloop_): Has old code from above function, instead of just calling it. * expr.c (ffeexpr_cb_comma_i_4_): Don't skip over arbitrary token (such as EOS). * com.c (ffecom_init_zero_): Handle RECORD_TYPE and UNION_TYPE so -fno-zeros works with -femulated-complex. 1997-03-12 Dave Love * intrin.def: New intrinsics INT2, INT8, CPU_TIME. Fix AND, OR, XOR. [Integrated by burley, AND/OR/XOR already fixed, INT8 implementation changed/fixed.] Wed Mar 12 10:40:08 1997 Craig Burley * Make-lang.in ($(srcdir)/f/intdoc.texi): Simplify rules so building f/intdoc is not always necessary; remove f/intdoc after running it if it is built. Tue Mar 11 23:42:00 1997 Craig Burley * intrin.def (FFEINTRIN_impAND, FFEINTRIN_impOR, FFEINTRIN_impXOR): Use the IAND, IOR, and IEOR implementations of these, instead of crashing in ffecom_expr_intrinsic_ or adding case labels there. Mon Mar 10 22:51:23 1997 Craig Burley * intdoc.c: Fix so any C compiler can compile this. Fri Feb 28 13:16:50 1997 Craig Burley * Version 0.5.20 released. Fri Feb 28 01:45:25 1997 Craig Burley * Make-lang.in (RUNTIMESTAGESTUFF, LIBU77STAGESTUFF): Move some files incorrectly in the former to the latter, and add another file or two to the latter. New meanings for (KIND=n), and new denotations in the little language describing intrinsics: * com.c (ffecom_init_0): Assign new meanings. * intdoc.c: Document new meanings. Support the new denotations. * intrin.c: Employ new meanings, mapping them to internal values (which are the same as they ever were for now). Support the new denotations. * intrin.def: Switch DEFIMP table to the new denotations. * intrin.c (ffeintrin_check_): Fix bug that was leaving LOC() and %LOC() returning INTEGER*4 on systems where it should return INTEGER*8. * type.c: Canonicalize function definitions, for etags and such. Wed Feb 26 20:43:03 1997 Craig Burley * com.c (ffecom_init_0): Choose INTEGER(KIND=n) types, where n is 2, 3, and 4, according to the new docs instead of according to the old C correspondences (which seem less useful at this point). * equiv.c (ffeequiv_destroy_): New function. (ffeequiv_layout_local_): Use this new function whenever the laying out of a local equivalence chain is aborted for any reason. Otherwise ensure that symbols no longer reference the stale ffeequiv entries that result when they are killed off in this procedure. Also, the rooted symbol is one that has storage, it really is irrelevant whether it has an equiv entry at this point (though the code to remove the equiv entry was put in at the end, just in case). (ffeequiv_kill): When doing internal checks, make sure the victim isn't named by any symbols it points to. Not as complete a check as looking through the entire symbol table (which does matter, since some code in equiv.c used to remove symbols from the lists for an ffeequiv victim but not remove that victim as the symbol's equiv info), but this check did find some real bugs in the code (that were fixed). Mon Feb 24 16:42:13 1997 Craig Burley * com.c (ffecom_expr_intrinsic_): Fix a couple of warnings about uninitialized variables. * intrin.c (ffeintrin_check_): Ditto, but there were a couple of _real_ uninitialized-variable _bugs_ here! (ffeintrin_fulfill_specific): Ditto, no real bug here. Sun Feb 23 15:01:20 1997 Craig Burley Clean up diagnostics (especially about intrinsics): * bad.def (FFEBAD_UNIMPL_STMT): Remove. (FFEBAD_INTRINSIC_*, FFEBAD_NEED_INTRINSIC): Clean these up so they're friendlier. (FFEBAD_INTRINSIC_CMPAMBIG): New. * intrin.c (ffeintrin_fulfill_generic, ffeintrin_fulfill_specific, ffeintrin_is_intrinsic): Always choose generic or specific name text (which is for doc purposes anyway) over implementation name text (which is for internal use). * intrin.def: Use more descriptive name texts for generics and specifics in cases where the names themselves are not enough (e.g. IDATE, which has two forms). Fix some intrinsic mappings: * intrin.def (FFEINTRIN_specIDINT, FFEINTRIN_specAND, FFEINTRIN_specDFLOAT, FFEINTRIN_specDREAL, FFEINTRIN_specOR, FFEINTRIN_specXOR): Now have their own implementations, instead of borrowing from others. (FFEINTRIN_specAJMAX0, FFEINTRIN_specAJMIN0, FFEINTRIN_specBJTEST, FFEINTRIN_specDFLOTJ, FFEINTRIN_specFLOATJ, FFEINTRIN_specJIABS, FFEINTRIN_specJIAND, FFEINTRIN_specJIBCLR, FFEINTRIN_specJIBITS, FFEINTRIN_specJIBSET, FFEINTRIN_specJIDIM, FFEINTRIN_specJIDINT, FFEINTRIN_specJIDNNT, FFEINTRIN_specJIEOR, FFEINTRIN_specJIFIX, FFEINTRIN_specJINT, FFEINTRIN_specJIOR, FFEINTRIN_specJISHFT, FFEINTRIN_specJISHFTC, FFEINTRIN_specJISIN, FFEINTRIN_specJMAX0, FFEINTRIN_specJMAX1, FFEINTRIN_specJMIN0, FFEINTRIN_specJMIN1, FFEINTRIN_specJMOD, FFEINTRIN_specJNINT, FFEINTRIN_specJNOT,): Turn these implementations off, since it's not clear just what types they expect in the context of portable Fortran. (DFLOAT): Now in FVZ family, since f2c supports them Support intrinsic inquiry functions (BIT_SIZE, LEN): * intrin.c: Allow `i' in . * intrin.def (FFEINTRIN_impBIT_SIZE, FFEINTRIN_impLEN): Mark args with `i'. Sat Feb 22 13:34:09 1997 Craig Burley Only warn, don't error, for reference to unimplemented intrinsic: * bad.def (FFEBAD_INTRINSIC_UNIMPLW): Warning version of _UNIMPL. * intrin.c (ffeintrin_is_intrinsic): Use new warning version of _UNIMPL (FFEBAD_INTRINSIC_UNIMPLW). Complain about REAL(Z) and AIMAG(Z) (Z is DOUBLE COMPLEX): * bad.def (FFEBAD_INTRINSIC_CMPAMBIG): New diagnostic. * expr.c: Needed #include "intrin.h" anyway. (ffeexpr_token_intrincheck_): New function handles delayed diagnostic for "REAL(REAL(expr)" if next token isn't ")". (ffeexpr_token_arguments_): Do most of the actual checking here. * intrin.h, intrin.c (ffeintrin_fulfill_specific): New argument, check_intrin, to tell caller that intrin is REAL(Z) or AIMAG(Z). All callers updated, mostly to pass NULL in for this. (ffeintrin_check_): Also has new arg check_intrin for same purpose. All callers updated the same way. * intrin.def (FFEINTRIN_impAIMAG): Change return type from "R0" to "RC", to accommodate f2c (and perhaps other non-F90 F77 compilers). * top.h, top.c: New option -fugly-complex. New GNU intrinsics REALPART, IMAGPART, and COMPLEX: * com.c (ffecom_expr_intrinsic_): Implement impCOMPLEX and impREALPART here. (specIMAGPART => specAIMAG.) * intrin.def: Add the intrinsics here. Rename implementations of VXTIDATE and VXTTIME to IDATEVXT and TIMEVXT, so they sort more consistently: * com.c (ffecom_expr_intrinsic_): * intrin.def: Delete intrinsic group `dcp', add `gnu', etc.: * intrin.c (ffeintrin_state_family): FFEINTRIN_familyGNU replaces FFEINTRIN_familyDCP, and gets state from `gnu' group. Get rid of FFEINTRIN_familyF2Z, nobody needs it. Move FFEINTRIN_specDCMPLX from DCP family to FVZ family, as f2c has it. Move FFEINTRIN_specDFLOAT from F2C family to FVZ family. (FFEINTRIN_specZABS, FFEINTRIN_specZCOS, FFEINTRIN_specZEXP, FFEINTRIN_specZLOG, FFEINTRIN_specZSIN, FFEINTRIN_specZSQRT): Move these from F2Z family to F2C family. * intrin.h (FFEINTRIN_familyF2Z, FFEINTRIN_familyDCP): Remove. (FFEINTRIN_familyGNU): Add. * top.h, top.c: Replace `dcp' with `gnu'. * com.c (ffecom_expr_intrinsic_): Clean up by collecting simple conversions into one nice, conceptual place. Fix up some intrinsic subroutines (MVBITS, KILL, UMASK) to properly push and pop call temps, to avoid wasting temp registers. * g77.c (doit): Toon says variables should be defined before being referenced. Spoilsport. * intrin.c (ffeintrin_check_): Now Dave's worried about warnings about uninitialized variables. Okay, so for basic return values 'g' and 's', they _were_ uninitialized -- is determinism really _that_ useful? * intrin.def (FFEINTRIN_impFGETC): Fix STATUS argument so that it is INTENT(OUT) instead of INTENT(IN). 1997-02-21 Dave Love * intrin.def, com.c: Support Sun-type `short' and `long' intrinsics. Perhaps should also do Microcruft-style `int2'. Thu Feb 20 15:16:53 1997 Craig Burley * com.c (ffecom_expr_intrinsic_): Clean up indentation. Support SECONDSUBR intrinsic implementation. Rename SECOND to SECONDFUNC for direct support via library. * g77.c: Fix to return proper status value to shell, by obtaining it from processes it spawns. * intdoc.c: Fix minor typo. * intrin.def: Turn SECOND into generic that maps into function and subroutine forms. * intrin.def: Make FLOAT and SNGL into specific intrinsics. * intrin.def, intrin.h: Change the way DEFGEN and DEFSPEC macros work, to save on verbage. Mon Feb 17 02:08:04 1997 Craig Burley New subsystem to automatically generate documentation on intrinsics: * Make-lang.in ($(srcdir)/f/g77.info, $(srcdir)/f/g77.dvi): Move g77 doc rules around. Add to g77 doc rules the new subsystem. (f77.mostlyclean, f77.maintainer-clean): Also clean up after new doc subsystem. * intdoc.c, intdoc.h: New doc subsystem code. * intrin.h [FFEINTRIN_DOC]: When 1, don't pull in stuff not needed by doc subsystem. Improve on intrinsics mechanism to both be more self-documenting and to catch more user errors: * intrin.c (ffeintrin_check_): Recognize new arg-len and arg-rank information, and check it. Move goto and signal indicators to the basic type. Permit reference to arbitrary argument number, not just first argument (for BESJN and BESYN). (ffeintrin_init_0): Check and accept new notations. * intrin.c, intrin.def: Value in COL now identifies arguments starting with number 0 being the first. Some minor intrinsics cleanups (resulting from doc work): * com.c (ffecom_expr_intrinsic_): Implement FLUSH directly once again, handle its optional argument, so it need not be a generic (awkward to handle in docs). * intrin.def (BESJ0, BESJ1, BESJN, BESY0, BESY1, BESYN, CHDIR, CHMOD, CTIME, DBESJ0, DBESJ1, DBESJN, DBESY0, DBESY1, DBESYN, DDIM, ETIME, FGETC, FNUM, FPUTC, FSTAT, GERROR, GETCWD, GETGID, GETLOG, GETPID, GETUID, GMTIME, HOSTNM, IDATE, IERRNO, IIDINT, IRAND, ISATTY, ITIME, JIDINT, LNBLNK, LSTAT, LTIME, MCLOCK, PERROR, SRAND, SYMLNK, TTYNAM, UMASK): Change capitalization of initcaps (official) name to be consistent with Burley's somewhat arbitrary rules. (BESJN, BESYN): These have return arguments of same type as their _second_ argument. (FLUSH): Now a specific, not generic, intrinsic, with one optional argument. (FLUSH1): Eliminated. Add arg-len and arg-rank info to several intrinsics. (ITIME): Change argument type from REAL to INTEGER. Tue Feb 11 14:04:42 1997 Craig Burley * Make-lang.in (f771): Invocation of Makefile now done with $(srcdir)=gcc to go along with $(VPATH)=gcc. ($(srcdir)/f/runtime/configure, $(srcdir)/f/runtime/libU77/configure): Break these out so spurious triggers of this rule don't happen (as when configure.in is more recent than libU77/configure). (f77.rebuilt): Distinguish source versus build files, so this target can be invoked from build directory and still work. * Makefile.in: This now expects $(srcdir) to be the gcc source directory, not gcc/f, to agree with $(VPATH). Accordingly, $(INCLUDES) has been fixed, various cruft removed, the removal of f771 has been fixed to remove the _real_ f771 (not the one in gcc's parent directory), and so on. * lex.c: Part of ffelex_finish_statement_() now done by new function ffelex_prepare_eos_(), so that, in one popular case, the EOS can be prepared while the pointer is at the end of the non-continued line instead of the end of the line that marks no continuation. This improves the appearance of diagnostics substantially. Mon Feb 10 12:44:06 1997 Craig Burley * Make-lang.in: runtime Makefile's, and include/f2c.h, also depend on f/runtime/configure and f/runtime/libU77/configure. Fix various libU77 routines: * com-rt.def (FFECOM_gfrtCTIME, FFECOM_gfrtMCLOCK, FFECOM_gfrtTIME): These now use INTEGER*8 for time values, for compatibility with systems like Alpha. (FFECOM_gfrtSYSTEM_CLOCK, FFECOM_gfrtTTYNAM): Delete incorrect trailing underscore in routine names. * intrin.c, intrin.def: Support INTEGER*8 return values and arguments ('4'). Change FFEINTRIN_impCTIME, FFEINTRIN_impMCLOCK, and FFEINTRIN_impTIME accordingly. (ffeintrin_is_intrinsic): Don't give caller a clue about form of intrinsic -- shouldn't be needed at this point. Cope with generic intrinsics that are subroutines and functions: * com.c (ffecom_finish_symbol_transform_, ffecom_expr_transform_): Don't transform an intrinsic that is not known to be a subroutine or a function. (Maybe someday have to avoid transforming any intrinsic with an undecided or unknown implementation.) * expr.c (ffeexpr_declare_unadorned_, ffeexpr_declare_parenthesized_): Ok to invoke generic intrinsic that has at least one subroutine form as a subroutine. Ok to pass intrinsic as actual arg if it has a known specific intrinsic form that is valid as actual arg. (ffeexpr_declare_parenthesized_): An unknown kind of intrinsic has a paren_type chosen based on context. (ffeexpr_token_arguments_): Build funcref/subrref based on context, not on kind of procedure being called. * intrin.h, intrin.c (ffeintrin_is_intrinsic): Undo changes of Tue Feb 4 23:12:04 1997 by me, change all callers to leave intrinsics as FFEINFO_kindNONE at this point. (Some callers also had unused variables deleted as a result.) Enable all intrinsic groups (especially f90 and vxt): * target.h (FFETARGET_defaultSTATE_DCP, FFETARGET_defaultSTATE_F2C, FFETARGET_defaultSTATE_F90, FFETARGET_defaultSTATE_MIL, FFETARGET_defaultSTATE_UNIX, FFETARGET_defaultSTATE_VXT): Delete these macros, let top.c set them directly. * top.c (ffeintrinsic_state_dcp_, ffe_intrinsic_state_f2c_, ffe_intrinsic_state_f90_, ffe_intrinsic_state_mil_, ffe_intrinsic_state_unix_, ffe_intrinsic_state_vxt_): Enable all these directly. Sat Feb 8 03:21:50 1997 Craig Burley * g77.c: Incorporate recent changes to ../gcc.c. For version magic (e.g. `g77 -v'), instead of compiling /dev/null, write, compile, run, and then delete a small program that prints the version numbers of the three components of libf2c (libF77, libI77, and libU77), so we get this info with bug reports. Also, this change reduces the chances of accidentally linking to an old (complex-alias-problem) libf2c. Fix `-L' so the argument is expected in `-Larg'. * com.h (FFECOM_f2cLONGINT): For INTEGER*8 support in f2c.h, dynamically determine proper type here, instead of assuming `long long int' is correct. Tue Feb 4 23:12:04 1997 Craig Burley Add libU77 library from Dave Love : * Make-lang.in (f77-runtime): Depend on new Makefile. (f/runtime/libU77/Makefile): New rule. Also configure libU77. ($(srcdir)/f/runtime/configure: Use Makefile.in, so configuration doesn't have to have happened. (f77.mostlyclean, f77.clean, f77.distclean, f77.maintainer-clean): Some fixups here, but more work needed. (RUNTIMESTAGESTUFF): Add libU77's config.status. (LIBU77STAGESTUFF, f77.stage1, f77.stage2, f77.stage3, f77.stage4): New macro, appropriate uses added. * com-rt.def: Add libU77 procedures. * com.c (ffecom_f2c_ptr_to_integer_type_node, ffecom_f2c_ptr_to_real_type_node): New type nodes. (FFECOM_rttypeCHARACTER_): New type of run-time function. (ffecom_char_args_): Handle CHARACTER*n intrinsics where n != 1 here, instead of in ffecom_expr_intrinsic_. (ffecom_expr_intrinsic_): New code to handle new intrinsics. In particular, change how FFEINTRIN_impFLUSH is handled. (ffecom_make_gfrt_): Handle new type of run-time function. (ffecom_init_0): Initialize new type nodes. * config-lang.in: New libU77 directory. * intrin.h, intrin.c (ffeintrin_is_intrinsic): Handle potential generic for subroutine _and_ function specifics via two new arguments. All callers changed. Properly ignore deleted/disabled intrinsics in resolving generics. (ffeintrin_check_, ffeintrin_init_0): Handle CHARACTER intrinsics of (*) length. * intrin.def: Permission granted by FSF to place this in public domain, which will allow it to serve as source for both g77 program and its documentation. Add libU77 intrinsics. (FLUSH): Now a generic, not specific, intrinsic. (DEFIMP): Now support return modifier for CHARACTER intrinsics. * com-rt.def (FFECOM_gfrtDIM, FFECOM_gfrtERF, FFECOM_gfrtERFC, FFECOM_gfrtEXP, FFECOM_gfrtSIGN, FFECOM_gfrtSIN, FFECOM_gfrtSINH, FFECOM_gfrtTAN, FFECOM_gfrtTANH, FFECOM_gfrtPOW_RI): Change "&r" to "&f". Sat Feb 1 12:15:09 1997 Craig Burley * Version 0.5.19.1 released. * com.c (ffecom_expr_, ffecom_expr_intrinsic_, ffecom_tree_divide_): FFECOM_gfrtPOW_ZI, FFECOM_gfrtCONJG, FFECOM_gfrtDCONJG, FFECOM_gfrtCCOS, FFECOM_gfrtCDCOS, FFECOM_gfrtCLOG, FFECOM_gfrtCDLOG, FFECOM_gfrtCSIN, FFECOM_gfrtCDSIN, FFECOM_gfrtCSQRT, FFECOM_gfrtCDSQRT, FFECOM_gfrtDIV_CC, FFECOM_gfrtDIV_ZZ: These all require result to _not_ overlap one or more inputs. Sat Feb 1 00:25:55 1997 Craig Burley * com.c (ffecom_init_0): Do internal checks only if -fset-g77-defaults not specified. Fix %LOC(), LOC() to return sufficiently wide type: * com.h, com.c (ffecom_pointer_kind_, ffecom_label_kind_, ffecom_pointer_kind(), ffecom_label_kind()): New globals and accessor macros hold kind for integer pointers on target machine. (ffecom_init_0): Determine narrowest INTEGER type that can hold a pointer (usually INTEGER*4 or INTEGER*8), store it in ffecom_pointer_kind_, etc. * expr.c (ffeexpr_cb_end_loc_): Use right type for %LOC(). * intrin.c (ffeintrin_check_, ffeintrin_init_0): Support new 'p' kind for type of intrinsic. * intrin.def (FFEINTRIN_impLOC): Returns "Ip" instead of "I1", so LOC() type is correct for target machine. Support -fugly-assign: * lang-options.h, top.h, top.c (ffe_decode_option): Accept -fugly-assign and -fno-ugly-assign. * com.c (ffecom_expr_): Handle -fugly-assign. * expr.c (ffeexpr_finished_): Check right type for ASSIGN contexts. Fri Jan 31 14:30:00 1997 Craig Burley Remove last vestiges of -fvxt-not-f90: * stb.c (ffestb_R10012_, ffestb_R10014_, ffestb_V0201_): top.c, top.h: Fri Jan 31 02:13:54 1997 Craig Burley * top.c (ffe_decode_option): Warn if -fugly is specified, it'll go away soon. * symbol.h: No need to #include "bad.h". Reorganize features from -fvxt-not-f90 to -fvxt: * lang-options.h, top.h, top.c: Accept -fvxt and -fno-vxt, but not -fvxt-not-f90 or -ff90-not-vxt. Warn if the latter two are used. * expr.c (ffeexpr_nil_rhs_): Double-quote means octal constant. (ffeexpr_token_rhs_): Double-quote means octal constant. * target.h (FFETARGET_defaultIS_VXT_NOT_90): Delete macro definition, no longer needed. Make some -ff90 features the default: * data.c (ffedata_value): DATA implies SAVE. * src.h (ffesrc_is_name_noninit): Underscores always okay. Fix up some more #error directives by quoting their text: * bld.c (ffebld_constant_is_zero): * target.h: Sat Jan 18 18:22:09 1997 Craig Burley * g77.c (lookup_option, main): Recognize `-Xlinker', `-Wl,', `-l', `-L', `--library-directory', `-o', `--output'. (lookup_option): Don't depend on SWITCH_TAKES_ARG being correct, it might or might not have `-x' in it depending on host. Return NULL argument if it would be an empty string. (main): If no input files (by gcc.c's definition) but `-o' or `--output' specified, produce diagnostic to avoid overwriting output via gcc. Recognize C++ `+e' options. Treat -L as another non-magical option (like -B). Don't append_arg `-x' twice. Fri Jan 10 23:36:00 1997 Craig Burley * top.c [BUILT_FOR_270] (ffe_decode_option): Make -fargument-noalias-global the default. Fri Jan 10 07:42:27 1997 Craig Burley Enable inlining of previously-compiled program units: * com.c (ffecom_do_entry_, ffecom_start_progunit_): Register new public function in ffeglobal database. (ffecom_sym_transform_): Any GLOBAL or potentially GLOBAL symbol should be looked up in ffeglobal database and that tree node used, if found. That way, gcc knows the references are to those earlier definitions, so it can emit shorter branches/calls, inline, etc. (ffecom_transform_common_): Minor change for clarity. * expr.c (ffeexpr_sym-lhs_call_, ffeexpr_sym_lhs_extfunc_, ffeexpr_sym_rhs_actualarg_, ffeexpr_paren_rhs_let_, ffeexpr_token_funsubstr_): Globalize symbol as needed. * global.c (ffeglobal_promoted): New function to look up existing local symbol in ffeglobal database. * global.h: Declare new function. * name.h (ffename_token): New macro, plus alphabetize. * stc.c (ffestc_R1207_item): Globalize EXTERNAL symbol. * stu.c (ffestu_sym_end_transition, ffestu_sym_exec_transition): Globalize symbol as needed. * symbol.h, symbol.c (ffesymbol_globalize): New function. Thu Jan 9 14:20:00 1997 Craig Burley * ste.c (ffeste_R809): Produce a diagnostic for SELECT CASE on CHARACTER type, instead of crashing. Thu Jan 9 00:52:45 1997 Craig Burley * stc.c (ffestc_order_entry_, ffestc_order_format_, ffestc_R1226): Allow ENTRY and FORMAT before IMPLICIT NONE, by having them transition only to state 1 instead of state 2 (which is disallowed by IMPLICIT NONE). Mon Jan 6 22:44:53 1997 Craig Burley Fix AXP bug found by Rick Niles (961201-1.f): * com.c (ffecom_init_0): Undo my 1996-05-14 change, as it is incorrect and prevented easily finding this bug. * target.h [__alpha__] (ffetargetReal1, ffetargetReal2): Use int instead of long. (ffetarget_cvt_r1_to_rv_, ffetarget_cvt_rv_to_r1_, ffetarget_cvt_r2_to_rv_, ffetarget_cvt_rv_to_r2_): New functions that intercede for callers of REAL_VALUE_(TO|UNTO)_TARGET_(SINGLE|DOUBLE). All callers changed, and damaging casts to (long *) removed. Sun Jan 5 03:26:11 1997 Craig Burley * Make-lang.in (g77, g77-cross): Depend on both g77.c and zzz.c, in $(srcdir)/f/. Better design for -fugly-assumed: * stc.c (ffestc_R501_item, ffestc_R524_item, ffestc_R547_item_object): Pass new is_ugly_assumed flag. * stt.c, stt.h (ffestt_dimlist_as_expr, ffestt_dimlist_type): New is_ugly_assumed flag now controls whether "1" is treated as "*". Don't treat "2-1" or other collapsed constants as "*". Sat Jan 4 15:26:22 1997 Craig Burley * stb.c (ffestb_R10012_): Don't confirm on FORMAT(A,) or even FORMAT(A,,B), as R1229 only warns about the former currently, and this seems reasonable. Improvements to diagnostics: * sta.c (ffesta_second_): Don't add any ffestb parsers unless they're specifically called for. Set up ffesta_tokens[0] before calling ffestc_exec_transition, else stale info might get used. (ffesta_save_): Do a better job picking which parser to run after running all parsers with no confirmed possibles. (FFESTA_maxPOSSIBLES_): Decrease from 100 now that so few possibles are ever on the list at a given time. (struct _ffesta_possible): Add named attribute. (ffesta_add_possible_exec_, ffesta_add_possible_nonexec_): Make these into macros that call a single function that now sets the named attribute. (ffesta_add_possible_unnamed_exec_, ffeseta_add_possible_unnamed_nonexec_): New macros. (ffesta_second_): Designate unnamed possibles as appropriate. * stb.c (ffestb_R1229, ffestb_R12291_): Use more general diagnostic, so things like "POINTER (FOO, BAR)" are diagnosed as unrecognized statements, not invalid statement functions. * stb.h, stb.c (ffestb_unimplemented): Remove function. 1996-12-30 Dave Love * com.c: #include libU77/config.h (ffecom_f2c_ptr_to_integer_type_node, ffecom_f2c_ptr_to_integer_type_node): New variables. (ffecom_init_0): Use them. (ffecom_expr_intrinsic_): Many news cases for libU77 intrinsics. * com-rt.def: New definitions for libU77. * intrin.def: Likewise. Also correct ftell arg spec. * Makefile.in (f/runtime/libU77/config.h): New target for com.c dependency. * Make-lang.in (f771): Depend on f/runtime/Makefile for the above. Sat Dec 28 12:28:29 1996 Craig Burley * stt.c (ffestt_dimlist_type): Treat ([...,]1) in dimlist as ([...,]*) if -fugly-assumed, so assumed-size array detected early enough. Thu Dec 19 14:01:57 1996 Craig Burley * target.h (FFETARGET_REAL_VALUE_FROM_INT_): Conditionalize definition on BUILT_FOR_280, not BUILT_WITH_280, since the name of the macro was (properly) changed since 0.5.19. Fix warnings/errors resulting from ffetargetOffset becoming `long long int' instead of `unsigned long' as of 0.5.19, while ffebitCount remains `unsigned long': * bld.c (ffebld_constantarray_dump): Avoid warnings by using loop var of appropriate type, and using casts. * com.c (ffecom_expr_): Use right type for loop var. (ffecom_sym_transform_, ffecom_transform_equiv_): Cast to right type in assertions. * data.c (ffedata_gather_, ffedata_value_): Cast to right type in assertions and comparisons. Wed Dec 18 12:07:11 1996 Craig Burley Patch from Alexandre Oliva : * Makefile.in (all.indirect): Don't pass -bbigtoc option to GNU ld. Cope with new versions of gcc: * com.h (BUILT_FOR_280): New macro. * com.c (ffecom_ptr_to_expr): Conditionalize test of OFFSET_REF. (ffecom_build_complex_constant_): Conditionalize calling sequence for build_complex. Sat Dec 7 07:15:17 1996 Craig Burley * Version 0.5.19 released. Fri Dec 6 12:23:55 1996 Craig Burley * g77.c: Default to assuming "f77" is in $LANGUAGES, since the LANGUAGE_F77 macro isn't defined by anyone anymore (but might as well leave the no-f77 code in just in case). * Make-lang.in (g77, g77-cross): Don't define LANGUAGE_F77 anymore. 1996-12-06 Dave Love * Make-lang.in (g77, g77-cross): Revert to building `g77' or not conditional on `f77' in LANGUAGES. Wed Dec 4 13:08:44 1996 Craig Burley * Make-lang.in (g77, g77-cross): No libs or lib dependencies in case where "f77" is not in $LANGUAGES. * lex.c (ffelex_image_char_, ffelex_file_fixed, ffelex_file_free): Fixes to properly handle lines with null character, and too-long lines as well. * lex.c: Call ffebad_start_msg_lex instead of ffebad_start_msg throughout. Sun Dec 1 21:19:55 1996 Craig Burley Fix-up for 1996-11-25 changes: * com.c (ffecom_member_phase2_): Subtract out 0 offset for elegance and consistency with EQUIVALENCE aggregates. (ffecom_sym_transform_): Ditto for LOCAL/COMMON, and ensure we get the same parent storage area. * data.c (ffedata_gather_, ffedata_value_): Subtract out aggregate offset. Wed Nov 27 13:55:57 1996 Craig Burley * proj.h: Quote the text of the #error message, to avoid strange-looking diagnostics from non-gcc ANSI compilers. * top.c: Make -fno-debug-kludge the default. Mon Nov 25 20:13:45 1996 Craig Burley Provide more info on EQUIVALENCE mismatches: * bad.def (FFEBAD_EQUIV_MISMATCH): More detailed message. * equiv.c (ffeequiv_layout_local_, ffeequiv_layout_cblock): More details for FFEBAD_EQUIV_MISMATCH. Fix problem with EQUIVALENCE handling: * equiv.c (ffeequiv_layout_local_): Redesign algorithm -- old one was broken, resulting in rejection of good code. (ffeequiv_offset_): Add argument, change callers. Clean up the code, fix up the (probably unused) negative-value case for SYMTER. * com.c (ffecom_sym_transform_): For local EQUIVALENCE member, subtract out aggregate offset (which is <= 0). Thu Nov 21 12:44:56 1996 Craig Burley Change type of ffetargetOffset from `unsigned long' to `long long': * bld.c (ffebld_constantarray_dump): Change printf formats. * storag.c (ffestorag_dump): Ditto. * symbol.c (ffesymbol_report): Ditto. * target.h (ffetargetOffset_f): Ditto and change type itself. Handle situation where list of languages does not include f77: * Make-lang.in: Define LANGUAGE_F77 to 1 only if `f77' is in the $LANGUAGES macro for the build. * g77.c: Compile to a (nearly) no-op program if LANGUAGE_F77 is not defined to 1. Fixes to delay confirmation of READ, WRITE, and GOTO statements so the corresponding assignments to same-named CHAR*(*) arrays work: * stb.c (ffestb_R90915_, ffestb_91014_): New functions. (ffestb_goto3_, ffestb_goto5_): Move confirmation from 3 to 5 for the OPEN_PAREN case. (ffestb_R9091_, ffestb_R9094_, ffestb_R90913_, ffestb_R90914_, ffestb_R91012_, ffestb_R91013_): Use new functions, and confirm except for the OPEN_PAREN case. Fixes to not confirm declarations with an open paren where an equal sign or other assignment-like token might be, so the corresponding assignments to same-named CHAR*(*) arrays work: (ffestb_decl_entsp_5_): Move assertion so we crash on that first, if it turns out to be wrong, before the less-debuggable crash on mistaken confirmation. (ffestb_decl_entsp_6_, ffestb_decl_entsp_7_, ffestb_decl_entsp_8_): Include OPEN_PAREN in list of assignment-only tokens. Fix more diagnosed-crash bugs: * stu.c (ffestu_sym_end_transition): ANY-ize an adjustable array with bad dimension expressions even if still stateUNCERTAIN. (ffestu_symter_end_transition_, ffestu_symter_exec_transition_): Return TRUE for opANY as well. For code elegance, move opSYMTER case into first switch. 1996-11-17 Dave Love * lex.c: Fix last change. 1996-11-14 Dave Love * Make-lang.in, config-lang.in: Remove the (broken) libU77 stuff, pending 0.5.20. Thu Nov 14 15:40:59 1996 Craig Burley * bad.def (FFEBAD_UNIMPL_STMT): Explain that invalid intrinsic references can trigger this message, too. 1996-11-12 Dave Love * lex.c: Declare dwarfout routines. * config-lang.in: Sink grep o/p. Mon Nov 11 14:21:13 1996 Craig Burley * g77.c (main): Might as well print version number for --verbose as well. Thu Nov 7 18:41:41 1996 Craig Burley * expr.c, lang-options.h, target.h, top.c, top.h: Split out remaining -fugly stuff into -fugly-logint and -fugly-comma, leaving -fugly as simply a `macro' that expands into other options, and eliminate defaults for some of the ugly stuff in target.h. * Make-lang.in (gcc-cross): Compile zzz.c, not version.o (!), in to get version info for this target. * config-lang.in: Test for GBE patch application based on whether 2.6.x or 2.7.x GBE is detected. Wed Nov 6 14:19:45 1996 Craig Burley * Make-lang.in (g77): Compile zzz.c in to get version info. * g77.c: Add support for --help and --version. * g77.c (lookup_option): Short-circuit long-winded tests when second char is not hyphen, just to save a spot of time. Sat Nov 2 13:50:31 1996 Craig Burley * intrin.def: Add FTELL and FSEEK intrinsics, plus new `g' codes for alternate-return (GOTO) arguments. * intrin.c (ffeintrin_check_): Support `g' codes. * com-rt.def: Add ftell_() and fseek_() to database. * com.c (ffecom_expr_intrinsic_): Ditto. Also, let each subroutine intrinsic decide for itself what to do with tree_type, the default being NULL_TREE once again (so ffecom_call_ doesn't think it's supposed to cast the function call to the type in the fall-through case). * ste.c (ffeste_R909_finish): Don't special-case list-directed I/O, now that libf2c can return non-zero status codes. (ffeste_R910_finish): Ditto. (ffeste_io_call_): Simplify logic. (ffeste_io_impdo_): (ffeste_subr_beru_): (ffeste_R904): (ffeste_R907): (ffeste_R909_start): (ffeste_R909_item): (ffeste_R909_finish): (ffeste_R910_start): (ffeste_R910_item): (ffeste_R910_finish): (ffeste_R911_start): (ffeste_R923A): Ditto all the above. Thu Oct 31 20:56:28 1996 Craig Burley * config-lang.in, Make-lang.in: Rename flag file build-u77 to build-libu77, for consistency with install-libf2c and such. * config-lang.in: Don't complain about failure to patch if pre-2.7.0 gcc is involved (since our patch for that doesn't add support for tooning). Sat Oct 26 05:56:51 1996 Craig Burley * bad.def (FFEBAD_TYPELESS_TOO_LARGE): Remove this unused and redundant diagnostic. Sat Oct 26 00:45:42 1996 Craig Burley * target.c (ffetarget_integerhex): Fix dumb bug. 1996-10-20 Dave Love * gbe/2.7.2.1.diff: New file. * Makefile.in (F771_LDFLAGS): Add -bbigtoc for AIX4.1 up, suggested by endo@material.tohoku.ac.jp [among others!]. Sat Oct 19 03:11:14 1996 Craig Burley * bad.def, bld.c, bld.h, expr.c, lang-options.h, target.c, target.h, top.c, top.h (ffebld_constant_new_integerbinary, ffebld_constant_new_integerhex, ffebld_constant_new_integeroctal, ffeexpr_token_name_apos_name_, ffetarget_integerbinary, ffetarget_integerhex, ffetarget_integeroctal): Support new -fno-typeless-boz option with new functions, mods to existing octal-handling functions, new macros, new error messages, and so on. * com.c, lang-options.h, top.c, top.h (ffecom_notify_primary_entry): Print program unit name on stderr if -fno-silent (new option). * lang-options.h, top.c, top.h, stt.c (ffestt_dimlist_as_expr): Treat ([...,]1) in dimlist as ([...,]*) if -fugly-assumed (new option). * lang-options.h: Comment out options duplicated in gcc/toplev.c, because, somehow, having them commented in and building on my DEC Alpha results in a cc1 that always segfaults, and gdb that also segfaults whenever it debugs it up to init_lex() calling xmalloc() or so. Thu Oct 17 00:39:27 1996 Craig Burley * stb.c (ffestb_R10013_): Don't change meaning of .sign until after previous meaning/value used to set sign of value (960507-1.f). Sun Oct 13 22:15:23 1996 Craig Burley * top.c (ffe_decode_option): Don't set back-end flags that are nonexistent prior to gcc 2.7.0. Sun Oct 13 12:48:45 1996 Craig Burley * com.c (convert): Don't convert emulated complex expr to real (via REALPART_EXPR) if the target type is (emulated) complex. Wed Oct 2 21:57:12 1996 Craig Burley * com.c (ffecom_debug_kludge_): Set DECL_IN_SYSTEM_HEADER so -Wunused doesn't complain about these manufactured decls. (ffecom_expr_): Ditto, for original (non-ASSIGN'ed) variable. (ffecom_transform_equiv_): Clear DECL_IGNORED_P for aggregate area so it shows up as a debug-accessible symbol. (pushdecl): Default for "invented" identifiers (a g77-specific concept for now) is that they are artificial, in system header, ignored for debugging purposes, used, and (for types) suppressed. This ought to be overkill. Fri Sep 27 23:13:07 1996 Craig Burley * ste.c (ffeste_begin_iterdo_, ffeste_end_iterdo_): Support one-trip DO loops (F66-style). * lang-options.h, top.c, top.h (-fonetrip): New option. Thu Sep 26 00:18:40 1996 Craig Burley * com.c (ffecom_debug_kludge_): New function. (ffecom_sym_transform_): Use new function for COMMON and EQUIVALENCE members. * lang-options.h, top.c, top.h (-fno-debug-kludge): New option. 1996-09-24 Dave Love * Make-lang.in (include/f2c.h): Remove dependencies on xmake_file and tmake_file. They expand inconsistently in 2.8 c.f. 2.7; $(GCC_PARTS) depends on them anyhow. 1996-09-22 Dave Love * config-lang.in: Add --enable-libu77 option handling. * Make-lang.in: Conditionally add --enable-libu77 when running runtime configure. Define LIBU77STAGESTUFF and use it in relevant rules. 1996-08-21 Dave Love * Make-lang.in (f77-runtime): `stmp-hdrs' should have been `stmp-headers'. 1996-08-20 Dave Love * Make-lang.in (f77-runtime): Depend on stmp-hdrs, not stmp-int-hdrs, since libF77 needs float.h. Sat Jun 22 18:17:11 1996 Craig Burley * com.c (ffecom_tree_divide_): Fix RECORD_TYPE case to look at type of first field, properly, to determine whether to call c_div or z_div. Tue Jun 4 04:27:18 1996 Craig Burley * com.c (ffecom_build_complex_constant_): Explicitly specify TREE_PURPOSE. (ffecom_expr_): Fix thinko. (ffecom_2): For COMPLEX_EXPR, explicitly specify TREE_PURPOSE. Mon May 27 16:23:43 1996 Craig Burley Changes to optionally avoid gcc's back-end complex support: * com.c (ffecom_stabilize_aggregate_): New function. (ffecom_convert_to_complex_): New function. (ffecom_make_complex_type_): New function. (ffecom_build_complex_constant_): New function. (ffecom_expr_): For opCONVERT of non-COMPLEX to COMPLEX, don't bother explicitly converting to the subtype first, because gcc does that anyway, and more code would have to be added to find the subtype for the emulated-complex case. (ffecom_f2c_make_type_): Use ffecom_make_complex_type_ instead of make_node etc. to make a complex type. (ffecom_1, ffecom_2): Translate operations on COMPLEX operands to appropriate operations when emulating complex. (ffecom_constantunion): Use ffecom_build_complex_constant_ instead of build_complex to build a complex constant. (ffecom_init_0): Change point at which types are laid out for improved consistency. Use ffecom_make_complex_type_ instead of make_node etc. to make a complex type. Always calculate storage sizes from TYPE_SIZE, never TYPE_PRECISION. (convert): Use e, not expr, since we've copied into that anyway. For RECORD_TYPE cases, do emulated-complex conversions. (ffecom_f2c_set_lio_code_): Always calculate storage sizes from TYPE_SIZE, never TYPE_PRECISION. (ffecom_tree_divide_): Allow RECORD_TYPE to also be handled by run-time library. (ffecom_expr_intrinsic_): Handle possible RECORD_TYPE as argument to AIMAG intrinsic. * top.h, top.c, lang-options.h: Support new -f(no-)emulate-complex option. * com.c (ffecom_sym_transform_): Clarify and fix typos in comments. Mon May 20 02:06:27 1996 Craig Burley * target.h: Use new REAL_VALUE_UNTO_TARGET_* macros instead of REAL_VALUE_FROM_TARGET_DOUBLE and _SINGLE. Explicitly use long instead of HOST_WIDE_INT for emulation of ffetargetReal1 and ffetargetReal2. 1996-05-20 Dave Love * config-lang.in: Test for patch being applied with flag_move_all_movables in toplev.c. * install.texi (Patching GNU Fortran): Mention overriding X_CFLAGS rather than editing proj.h on SunOS4. * Make-lang.in (F77_FLAGS_TO_PASS): Add X_CFLAGS (convenient for SunOS4 kluge, in particular). (f77.{,mostly,dist}clean): Reorder things, in particular not to delete Makefiles too early. * g77.c (DEFAULT_SWITCH_TAKES_ARG): Define a la gcc.c in the current GCC snapshot. Tue May 14 00:24:07 1996 Craig Burley Changes for DEC Alpha AXP support: * com.c (ffecom_init_0): REAL_ARITHMETIC means internal REAL/DOUBLE PRECISION might well have a different size than the compiled type, so don't crash if this is the case. * target.h: Use `int' for ffetargetInteger1, ffetargetLogical1, and magical tests. Set _f format strings accordingly. Tue Apr 16 14:08:28 1996 Craig Burley * top.c (ffe_decode_option): -Wall no longer implies -Wsurprising. Sat Apr 13 14:50:06 1996 Craig Burley * com.c (ffecom_char_args_): If item is error_mark_node, set *length that way, too. * com.c (ffecom_expr_power_integer_): If either operand is error_mark_node, return that. * com.c (ffecom_intrinsic_len_): If item is error_mark_node, return that for length. * expr.c (ffeexpr_declare_unadorned_, ffeexpr_declare_parenthesized_): Instead of crashing on unexpected contexts, produce a diagnostic. * intrin.c (ffeintrin_check_), intrin.def (impSIGNAL): Allow procedure as second arg to SIGNAL intrinsic. * stu.c (ffestu_symter_end_transition_): New function. (ffestu_symter_exec_transition_): Return bool arg. Always transition symbol (don't inhibit when !whereNONE). (ffestu_sym_end_transition): If DUMMY/LOCAL arg has any opANY exprs in its dimlist, diagnose it so it doesn't make it through to later stages that try to deal with dimlist stuff. (ffestu_sym_exec_transition): If sym has any opANY exprs in its dimlist, diagnose it so it becomes opANY itself. * symbol.c (ffesymbol_error): If token arg is NULL, just ANY-ize the symbol -- don't produce diagnostic. Mon Apr 1 10:14:02 1996 Craig Burley * Version 0.5.18 released. Mon Mar 25 20:52:24 1996 Craig Burley * com.c (ffecom_expr_power_integer_): Don't generate code that compares COMPLEX (or, as it happens, REAL) via "LT_EXPR", since the back end crashes on that. (This code would never be executed anyway, but the test that avoids it has now been translated to control whether the code gets generated at all.) Fixes 960323-3.f. * com.c (ffecom_type_localvar_): Handle variable-sized dimension bounds expressions here, so they get calculated and saved on procedure entry. Fixes 960323-4.f. * com.c (ffecom_notify_init_symbol): Symbol has no init info at all if only zeros have been used to initialize it. Fixes 960324-0.f. * expr.c, expr.h (ffeexpr_type_combine): Renamed from ffeexpr_type_combine_ and now a public procedure; last arg now a token, instead of an internal structure used to extract a token. Now allows the outputs to be aliased with the inputs. Now allows a NULL token to mean "don't report error". (ffeexpr_reduced_bool2_, ffeexpr_reduced_eqop2_, ffeexpr_reduced_math2_, ffeexpr_reduced_power_, ffeexpr_reduced_relop2_): Handle new calling sequence for ffeexpr_type_combine. * (ffeexpr_convert): Don't put an opCONVERT node in just because the size is unknown; all downstream code should be able to deal without it being there anyway, and getting rid of it allows new intrinsic code to more easily combine types and such without generating bad code. * info.c, info.h (ffeinfo_kindtype_max): Rewrite to do proper comparison of size of types, not just comparison of their internal kind numbers (so I2.eq.I1 doesn't promote I1 to I2, rather the other way around). * intrin.c (ffeintrin_check_): Combine types of arguments in COL a la expression handling, for greater flexibility and permissiveness (though, someday, -fpedantic should report use of this kind of thing). Make sure Hollerith/typeless where CHARACTER expected is rejected. This all fixes 960323-2.f. * ste.c (ffeste_begin_iterdo_): Fix some more type conversions so INTEGER*2-laden DO loops don't crash at compile time on certain machines. Believed to fix 960323-1.f. * stu.c (ffestu_sym_end_transition): Certainly reject whereDUMMY not in any dummy list, whether stateUNCERTAIN or stateUNDERSTOOD. Fixes 960323-0.f. Tue Mar 19 13:12:40 1996 Craig Burley * data.c (ffedata_value): Fix crash on opANY, and simplify the code at the same time. * Make-lang.in (f77-runtime): Also depends on lib[FI]77/Makefile... (include/f2c.h...): ...which in turn depend on */Makefile.in. (f77.rebuilt): Rebuild runtime stuff too. * intrin.c (ffeintrin_check_): Accommodate TYPELESS/HOLLERITH types, convert args as necessary, etc. * expr.c (ffeexpr_convert): Fix test for TYPELESS/HOLLERITH to obey the docs; crash if no source token when error. (ffeexpr_collapse_convert): Crash if no token when error. Mon Mar 18 15:51:30 1996 Craig Burley * com.c (ffecom_init_zero_): Renamed from ffecom_init_local_zero_; now handles top-level (COMMON) initializations too. * bld.c (ffebld_constant_is_zero): * com.c (ffecom_symbol_transform_, ffecom_sym_transform_assign_, ffecom_transform_common_, ffecom_transform_equiv_): * data.c: * equiv.c: * equiv.h: * lang-options.h: * stc.c: * storag.c: * storag.h: * symbol.c: * symbol.h: * target.c: * target.h: * top.c: * top.h: All of this is mostly housekeeping-type changes to support -f(no-)zeros, i.e. not always stuff zero values into the initializer fields of symbol/storage objects, but still track that they have been given initial values. * bad.def: Fix wording for DATA-related diagnostics. * com.c (ffecom_sym_transform_assign_): Don't check any EQUIVALENCE stuff for local ASSIGN, the check was bad (crashing), and it's not necessary, anyway. * com.c (ffecom_expr_intrinsic_): For MAX and MIN, ignore null arguments as far arg[123], and fix handling of ANY arguments. (New intrinsic support now allows spurious trailing null arguments.) * com.c (ffecom_init_0): Add HOLLERITH (unsigned) equivalents for INTEGER*2, *4, and *8, so shift intrinsics and other things that need unsigned versions of signed types work. Sat Mar 16 12:11:40 1996 Craig Burley * storag.c (ffestorag_exec_layout): Treat adjustable local array like dummy -- don't create storage object. * com.c (ffecom_sym_transform_): Allow for NULL storage object in LOCAL case (adjustable array). Fri Mar 15 13:09:41 1996 Craig Burley * com.c (ffecom_sym_transform_): Allow local symbols with nonconstant sizes (adjustable local arrays). (ffecom_type_localvar_): Allow dimensions with nonconstant component (adjustable local arrays). * expr.c: Various minor changes to handle adjustable local arrays (a new case of stateUNCERTAIN). * stu.c (ffestu_sym_end_transition, ffestu_sym_exec_transition): Ditto. * symbol.def: Update docs to reflect these changes. * com.c (ffecom_expr_): Reduce space/time needed for opACCTER case by handling it here instead of converting it to opARRTER earlier on. (ffecom_notify_init_storage): Don't convert ACCTER to ARRTER. (ffecom_notify_init_symbol): Ditto. * com.c (ffecom_init_0): Crash and burn if any of the types' sizes, according to the GBE, disagrees with the sizes of the FFE's internal implementation. This might catch Alpha/SGI bugs earlier. Fri Mar 15 01:09:41 1996 Craig Burley * com-rt.def, com.c, com.h: Changes for rewrite of intrinsic handling. * com.c (ffecom_arglist_expr_): New function. (ffecom_widest_expr_type_): New function. (ffecom_expr_intrinsic_): Reorganize, some rewriting. (ffecom_f2c_make_type_): Layout complex types. (ffecom_gfrt_args_): New function. (ffecom_list_expr): Trivial change for consistency. * expr.c (ffeexpr_token_name_rhs_): Go back to getting type from specific, not implementation, info. (ffeexpr_token_funsubstr_): Set intrinsic implementation too! * intrin.c: Major rewrite of most portions. * intrin.def: Major rearchitecting of tables. * intrin.h (ffeintrin_basictype, ffeintrin_kindtype): Now (once again) take ffeintrinSpec as arg, not ffeintrinImp; for now, these return NONE, since they're not really needed and adding the necessary info to the tables is not trivial. (ffeintrin_codegen_imp): New function. * stc.c (ffestc_R1208_item): Change way ffeintrin funcs called, back to original per above; but comment out the code anyway. * intrin.c (ffe_init_0): Do internal checks only if -fset-g77-defaults not specified. * lang-options.h: Add -fset-g77-defaults option. * lang-specs.h: Always pass -fset-g77-defaults. * top.c, top.h: New option. Sat Mar 9 17:49:50 1996 Craig Burley * Make-lang.in (stmp-int-hdrs): Use --no-validate when generating the f77.rebuilt files (BUGS, INSTALL, NEWS) so cross-references can work properly in g77.info without a lot of hassle. Users can probably deal with the way they end up looking in the f77.rebuilt files. * bld.c (ffebld_constant_new_integer4_val): INTEGER*8 support -- new function. (ffebld_constant_new_logical4_val): New function. * com.c (ffecom_f2c_longint_type_node): New type. (FFECOM_rttypeLONGINT_): New return type code. (ffecom_expr_): Add code to invoke pow_qq instead of pow_ii for INTEGER4 (INTEGER*8) case. If ffecom_expr_power_integer_ returns NULL_TREE, just do the usual work. (ffecom_make_gfrt_): Handle new type. (ffecom_expr_power_integer_): Let caller do the work if in dummy-transforming case, since caller now knows about INTEGER*8 and such, by returning NULL_TREE. * expr.c (ffeexpr_reduced_power_): Complain about non-INTEGER raised to INTEGER4 (INTEGER*8) power. * target.c (ffetarget_power_integerdefault_integerdefault): Fix any**negative. * com.c (ffecom_expr_power_integer_): Fix (-1)**(-8) and similar to ABS() the integral result if the exponent is negative and even. * ste.c (ffeste_begin_iterdo_): Clean up a type ref. Always convert iteration count to _default_ INTEGER. * sta.c (ffesta_second_): Add BYTE and WORD type/stmts; changes by Scott Snyder . * stb.c (ffestb_decl_recursive): Ditto. (ffestb_decl_recursive): Ditto. (ffestb_decl_entsp_2_): Ditto. (ffestb_decl_entsp_3_): Ditto. (ffestb_decl_funcname_2_): Ditto. (ffestb_decl_R539): Ditto. (ffestb_decl_R5395_): Ditto. * stc.c (ffestc_establish_declstmt_): Ditto. * std.c (ffestd_R539item): Ditto. (ffestd_R1219): Ditto. * stp.h: Ditto. * str-1t.fin: Ditto. * str-2t.fin: Ditto. * expr.c (ffeexpr_finished_): For DO loops, allow any INTEGER type; convert LOGICAL (assuming -fugly) to corresponding INTEGER type instead of always default INTEGER; let later phases do conversion of DO start, end, incr vars for implied-DO; change checks for non-integral DO vars to be -Wsurprising warnings. * ste.c (ffeste_io_impdo_): Convert start, end, and incr to type of DO variable. * com.c (ffecom_init_0): Add new types for [IL][234], much of which was done by Scott Snyder . * target.c: Ditto. * target.h: Ditto. Wed Mar 6 14:08:45 1996 Craig Burley * top.c (ffe_init_gbe_): Make -frerun-loop-opt the default. Mon Mar 4 12:27:00 1996 Craig Burley * expr.c (ffeexpr_exprstack_push_unary_): Really warn only about two successive _arithmetic_ operators. * stc.c (ffestc_R522item_object): Allow SAVE of (understood) local entity. * top.c (ffe_decode_option): New -f(no-)second-underscore options. * top.h: New options. * com.c (ffecom_get_external_identifier_, ffecom_get_identifier_): New options. * Make-lang.in (f77.maintainer-clean): Clean f/BUGS, f/INSTALL, f/NEWS. ($(srcdir)/f/BUGS, $(srcdir)/f/INSTALL, $(srcdir)/f/NEWS): New rules. ($(srcdir)/f/g77.info, $(srcdir)/f/g77.dvi): Depend on f/bugs.texi and f/news.texi. (f77.install-man): Install f77 man pages (if enabled). (f77.uninstall): Uninstall info docs, f77 man pages (if enabled). * top.c (ffe_init_gbe_): New function. (ffe_decode_option, ffe_file): Call ffe_init_gbe_ to set defaults for gcc options. Sat Jan 20 13:57:19 1996 Craig Burley * com.c (ffecom_get_identifier_): Eliminate needless comparison of results of strchr. Tue Dec 26 11:41:56 1995 Craig Burley * Make-lang.in: Add rules for new files g77.texi, g77.info, and g77.dvi. Reorganize the *clean rules to more closely parallel gcc's. * config-lang.in: Exclude g77.info from diffs. Sun Dec 10 02:29:13 1995 Craig Burley * expr.c (ffeexpr_declare_unadorned_, ffeexpr_declare_parenthesized_): Break out handling of contextDATAIMPDO[INDEX,CTRL] so it's independent of symbol state. Don't exec-transition these here (let ffeexpr_sym_impdoitem_ handle that when appropriate). Don't "declare" them twice. Tue Dec 5 06:48:26 1995 Craig Burley * stc.c (ffestc_promote_sfdummy_): Allow whereNONE parent symbol, since it is not necessarily known whether it will become LOCAL or DUMMY. Mon Dec 4 03:46:55 1995 Craig Burley * lex.c (ffelex_display_token, ffelex_type_string_): Resurrect these from their old versions and update them for possible invocation from debugger. * lex.h (ffelex_display_token): Declare this in case anyone else wants to call it. * lex.c (ffelex_total_tokens_): Have this reflect actual allocated tokens, no longer include outstanding "uses" of tokens. * malloc.c, malloc.h (MALLOC_DEBUG): New macro to control checking of whether callers follow rules, now defaults to 0 for "no checking" to improve compile times. * malloc.c (malloc_pool_kill): Fix bug that could prevent subpool from actually being killed (wasn't setting its use count to 1). * proj.h, *.c (dmpout): Replace all occurrences of `stdout' and some of `stderr' with `dmpout', so where to dump debugging output can be easily controlled during build; add default for `dmpout' of `stderr' to proj.h. Sun Dec 3 00:56:29 1995 Craig Burley * com.c (ffecom_return_expr): Eliminate attempt at warning about unset return values, since the back end does this better, with better wording, and is not triggered by clearly working (but spaghetti) code as easily as this test. Sat Dec 2 08:28:56 1995 Craig Burley * target.c (ffetarget_power_*_integerdefault): Raising 0 to integer constant power should not be an error condition; if so, other code should catch 0 to any power, etc. * bad.def (FFEBAD_BAD_POWER): 0**integer now a warning instead of an error. Fri Dec 1 00:12:03 1995 Craig Burley (burley@gnu.ai.mit.edu) * bad.def: Clarify diagnostic regarding complex constant elements. * expr.c (ffeexpr_cb_comma_c_): Capitalize real/imaginary for clarified diagnostic. * com.c (ffecom_close_include_): Close the file! * lex.c (ffelex_file_fixed): Update line info if the line has any content, not just if it finishes a previous line or has a label. (ffelex_file_free): Clarify switch statement code. Sat Nov 18 19:37:22 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.17 released. Fri Nov 17 14:27:24 1995 Craig Burley (burley@gnu.ai.mit.edu) * Make-lang.in: Fix typo in comment. * Makefile.in (f/fini.o, f/proj-h.o): Don't use `$<' since not all makes support it (e.g. NeXT make), use explicit source name instead (with $(srcdir) and munging). (ASSERT_H): assert.h lives in source dir, not build dir. Thu Nov 16 12:47:50 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_init_0): Fix dumb bug in code to produce warning message about non-32-bit-systems. * stc.c (ffestc_R501_item): Parenthesize test to make warning go away (and perhaps fix bug). Thu Nov 16 03:43:33 1995 Craig Burley (burley@gnu.ai.mit.edu) * g77.c: Upgrade to 2.7.0's gcc.c. Fix -v to pass a temp name instead of "/dev/null" for "-o". Fri Nov 10 19:16:05 1995 Craig Burley (burley@gnu.ai.mit.edu) * ste.c (ffeste_begin_iterdo_): Add Toon's change to make loops faster on some machines (implement termination condition as "--i >= 0" instead of "i-- > 0"). Thu Nov 2 03:58:17 1995 Craig Burley (burley@gnu.ai.mit.edu) * Make-lang.in: Remove unnecessary $(exeext) a la cp/Make-lang.in. * com.c (ffecom_expr_): Restore old strategy for assignp variant of opSYMTER case...always return the ASSIGN version of var. That way, `-O -Wuninitialized' will catch "I=3;GOTO I;END" (though the diagnostic will refer to `__g77_ASSIGN_i'). * com.c (ffecom_expr_power_integer_): For constant rhs case, wrap every new eval of lhs in save_expr() so it is clear to back end that MULT_EXPR(lhs,lhs) has identical operands, otherwise for an rhs like 32767 it generates around 65K pseudo registers, with which stupid_life_analysis cannot cope (due to reg_renumber in regs.h being `short *' instead of `int *'). * com.c (ffecom_expr_): Speed up implementation of LOGICAL versions of opNOT, opAND, opOR, opXOR/opNEQV, and opEQV by assuming the values actually are kosher LOGICAL bit patterns. Also simplify code that implements some of the INTEGER versions of these. * com.c (skip_redundant_dir_prefix, read_name_map, ffecom_open_include_, signed_type, unsigned_type): Fold in changes to cccp.c made from 2.7.0 through ss-950826. * equiv.c (ffeequiv_layout_local_): Kill the equiv list if no syms in list. * expr.c (ffeexpr_reduced_eqop2_): Issue specific diagnostic regarding usage of .EQV./.NEQV. in preference to .EQ./.NE.. * intrin.c: Add ERF and ERFC as generic intrinsics. intrin.def: Same. * sta.c (ffesta_save_, ffesta_second_): Whoever calls ffestd_exec_begin must also set ffesta_seen_first_exec = TRUE, and anytime stc sees an exec transition, it must do both. stc.c (ffestc_eof): Same. * stc.c (ffestc_promote_sfdummy_): If failed implicit typing or CHARACTER*(*) arg, after calling ffesymbol_error, don't reset info to ENTITY/DUMMY, because ffecom_sym_transform_ doesn't expect such a thing with ANY/ANY type. * target.h (*logical*): Change some of these so they parallel changes in com.c, e.g. for _eqv_, use (l)==(r) instead of !!(l)==!!(r), to get a more faithful result. Fri Oct 27 07:06:59 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_sym_transform_): Simplify code for local EQUIVALENCE case. * expr.c (ffeexpr_exprstack_push_unary_): Warn about two successive operators. (ffeexpr_exprstack_push_binary_): Warn about "surprising" operator precedence, as in "-2**2". * lang-options.h: Add -W(no-)surprising options. * parse.c (yyparse): Don't reset -fpedantic if not -pedantic. * top.c (ffe_decode_option): Support new -Wsurprising option. * top.h: Ditto. Mon Oct 23 09:14:15 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_finish_symbol_transform_): Don't transform NONE/NONE (CHARACTER*(*)) vars, as these don't mean anything in debugging terms, and can't be turned into anything in the back end (so ffecom_sym_transform_ crashes on them). * com.c (ffecom_expr_): Change strategy for assignp variant of opSYMTER case...always return the original var unless it is not wide enough. * ste.c (ffeste_io_cilist_): Clarify diagnostic for ASSIGN involving too-narrow variable. This shouldn't happen, though. (ffeste_io_icilist_): Ditto. (ffeste_R838): Ditto. (ffeste_R839): Ditto. Thu Oct 19 03:21:20 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_sym_transform_assign_): Set TREE_STATIC using the same decision-making process as used for their twin variables, so ASSIGN can last across RETURN/CALL as appropriate. Fri Sep 22 20:21:18 1995 Craig Burley (burley@gnu.ai.mit.edu) * Makefile.in: fini is a host program, so it needs a host-compiled version of proj.o, named proj-h.o. f/fini, f/fini.o, and f/proj-h.o targets updated accordingly. * com.c (__eprintf): New function. Wed Sep 20 02:26:36 1995 Craig Burley (burley@gnu.ai.mit.edu) * lang-options.h: Add omitted -funix-intrinsics-* options. * malloc.c (malloc_find_inpool_): Check for infinite loop, crash if detected (user reports encountering them in some large programs, this might help track down the bugs). Thu Sep 7 13:00:32 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (lang_print_error_function): Don't dereference null pointer when outside any program unit. (ffecom_let_char_, ffecom_arg_ptr_to_expr): If catlist item or length ever error_mark_node, don't continue processing, since back-end functions like build_pointer_type crash on error_mark_node's (due to pushing bad obstacks, etc.). Wed Aug 30 15:58:35 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.16 released. Mon Aug 28 12:24:20 1995 Craig Burley (burley@gnu.ai.mit.edu) * bad.c (ffebad_finish): Fix botched message when no places are printed (due to unknown line info, etc.). * std.c (ffestd_subr_labels_): Do a better job finding line info in the case of typeANY and diagnostics. Fri Aug 25 15:19:29 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (DECL_ARTIFICIAL): Surround all references to this macro with #if !BUILT_FOR_270 and #endif. (init_lex): Surround print_error_function decl with #if !BUILT_FOR_270 and #endif. (lang_init): Call new ffelex_hash_kludge function to solve problem with preprocessed files that have INCLUDE statements. * lex.c (ffelex_getc_): New function. (ffelex_cfelex_): Use ffelex_getc_ instead of getc in any paths of code that can be affected by ffelex_hash_kludge. Don't make an EOF token for unrecognized token; set token to NULL instead, to avoid problems when not initialized. (ffelex_hash_): Use ffelex_getc_ instead of getc in any paths of code that can be affected by ffelex_hash_kludge. Test token returned by ffelex_cfelex_ for NULL, meaning unrecognized token. Get rid of useless used_up variable. Don't do ffewhere stuff or kill any tokens if in ffelex_hash_kludge. (ffelex_file_fixed, ffelex_file_free): Use ffelex_getc_ instead of getc in any paths of code that can be affected by ffelex_hash_kludge. (ffelex_hash_kludge): New function. * lex.h (ffelex_hash_kludge): New function. Wed Aug 23 15:17:40 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c: Implement -f(no-)underscoring options by always compiling in code to do it, and having that code inhibit itself when -fno-underscoring is in effect. This option overrides -f(no-)f2c for this purpose; -f(no-)f2c returns to it's <=0.5.15 behavior of affecting only how code is generated, not how/whether names are mangled. * target.h: Redo specification of appending underscores so the macros are named "_default" instead of "_is" and the two-underscore macro defaults to 1. * top.c, top.h (underscoring): Add appropriate stuff for the -f(no-)underscoring options. Tue Aug 22 10:25:01 1995 Craig Burley (burley@gnu.ai.mit.edu) * bad.c (ffebad_finish): Call report_error_function (in toplev.c) to better identify location of problem. Say "(continued):" instead of "(continued:)" for consistency. * com.c (ffecom_gen_sfuncdef_): Set and reset new ffecom_nested_entry_ variable to hold ffesymbol being compiled. (lang_print_error_function): New function from toplev.c. Use ffecom_nested_entry_ to help determine which name and kind-string to print. (ffecom_expr_intrinsic_): Handle EXIT and FLUSH invocations with different calling sequences than library functions. Have SIGNAL and SYSTEM push and pop calltemps, and convert their return values to the destination type (just in case). (FFECOM_rttypeINT_): New return type for `int', in case gcc/f/runtime/libF77/system_.c(system_) is really supposed to return `int' instead of `ftnint'. * com.h (report_error_function): Declare this. * equiv.c (ffeequiv_layout_local_): Don't forget to consider root variable itself as possible "first rooted variable", else might never set symbol and then crash later. * intrin.c (ffeintrin_check_exit_): Change to allow no args and rename to ffeintrin_check_int_1_o_ for `optional'. #define ffeintrin_check_exit_ and _flush_ to this new function, so intrin.def can refer to the appropriate names. * intrin.def (FFEINTRIN_impFLUSH): Validate using ffeintrin_check_flush_ so passing an INTEGER arg is allowed. * lex.c (ffelex_file_push_, ffelex_file_pop_): New functions to manage input_file_stack in gbe. (ffelex_hash_): Call new functions (instead of doing code). (ffelex_include_): Call new functions to update stack for INCLUDE (_hash_ handles cpp output of #include). Mon Aug 21 08:09:04 1995 Craig Burley (burley@gnu.ai.mit.edu) * Makefile.in: Put `-W' in front of every `-Wall', since 2.7.0 requires that to engage `-Wunused' for parameters. * com.c: Mark all parameters as artificial, so `-W -Wunused' doesn't complain about unused ones (since there's no way right not to individually specify attributes like `unused'). * proj.h: Don't #define UNUSED if already defined, regardless of host compiler. Sun Aug 20 16:03:56 1995 Craig Burley (burley@gnu.ai.mit.edu) * gbe/2.7.0.diff: Regenerate. * lang-options.h, lang-specs.h: If not __STDC__ (ANSI C), avoid doing anything, especially the stringizing in -specs.h. Thu Aug 17 03:36:12 1995 Craig Burley (burley@gnu.ai.mit.edu) * lang-specs.h: Remove useless optional settings of -traditional, since -traditional is always set anyway. Wed Aug 16 16:56:46 1995 Craig Burley (burley@gnu.ai.mit.edu) * Make-lang.in (F2C_INSTALL_FLAG, F2CLIBOK): More control over whether to install f2c-related stuff. (install-f2c-*): New targets to install f2c-related stuff in system, not just gcc, directories. * com.c: Change calls to ffecom_get_invented_identifier to use generally more predictable names. Change calls to build_range_type to ensure consistency of types of operands. (ffecom_get_external_identifier_): Change to accept symbol info, not just text, so it can use f2c flag for symbol to decide whether to append underscore(s). (ffecom_get_identifier_): Don't change names if f2c flag off for compilation. (ffecom_type_permanent_copy_): Use same type for new max as used for min. (ffecom_notify_init_storage): Offline fixups for stand-alone. * data.c (ffedata_gather): Explicitly test for common block, since it's no longer always the case that a local EQUIVALENCE group has no symbol ptr (it now can, if a user-predictable "rooted" symbol has been identified). * equiv.c: Add some debugging stuff. (ffeequiv_layout_local_): Set symbol ptr with user-predictable "rooted" symbol, for giving the invented aggregate a predictable name. * g77.c (append_arg): Allow for 20 extra args instead of 10. (main): For version-only case, add `-fnull-version' and, unless explicitly omitted, `-lf2c -lm'. * lang-options.h: New "-fnull-version" option. * lang-specs.h: Support ".fpp" suffix for preprocessed source (useful for OS/2, MS-DOS, other case-insensitive systems). * stc.c (ffestc_R544_equiv_): Swap way lists are merged so this is consistent with the order in which lists are built, making user predictability of invented aggregate name much higher. * storag.c, storag.h (FFESTORAG_typeDUMMY): Delete this enum. * top.c: Accept, but otherwise ignore, `-fnull-version'. Tue Aug 15 07:01:07 1995 Craig Burley (burley@gnu.ai.mit.edu) * DOC, INSTALL, PROJECTS: Extensive improvements to documentation. Sun Aug 13 01:55:18 1995 Craig Burley (burley@gnu.ai.mit.edu) * INSTALL (f77-install-ok): Document the use of this file. * Make-lang.in (F77_INSTALL_FLAG): New flag to control whether to install an `f77' command (based on whether a file named `f77-install-ok' exists in the source or build directory) to replace the broken attempt to use comment lines to avoid installing `f77' (broken in the sense that it prevented installation of `g77'). Mon Aug 7 06:14:26 1995 Craig Burley (burley@gnu.ai.mit.edu) * DOC: Add new sections for g77 & gcc compiler options, source code form, and types, sizes and precisions. Remove lots of old "delta-version" info, or at least summarize it. * INSTALL: Add info here that used to be in DOC. Other changes. * g77.c (lookup_option, main): Check for --print-* options, so we avoid adding version-determining stuff. Wed Jul 26 15:51:03 1995 Craig Burley (burley@gnu.ai.mit.edu) * Make-lang.in, Makefile.in (input.j, INPUT_H): New file. Update dependencies accordingly. * bad.c (ffebad_here): Okay to use unknown line/col. * compilers.h (@f77-cpp-input): Remove -P option now that # directives are handled by f771. Update other options to be more consistent with @c in gcc/gcc.c. Don't run f771 if -E specified, etc., a la @c. (@f77): Don't run f771 if -E specified, etc., a la @c. * config-lang.in: Avoid use of word "guaranteed". * input.j: New file to wrap around gcc/input.h. * lex.j: Add support for parsing # directives output by cpp. (ffelex_cfebackslash_): New function. (ffelex_cfelex_): New function. (ffelex_get_directive_line_): New function. (ffelex_hash_): New function. (ffelex_include_): Change to not use ffewhere_file_(begin|end). Also fix bug in pointing to next line (for diagnostics, &c) following successful INCLUDE. (ffelex_next_line_): New function that does chunk of code seen in several places elsewhere in the lexers. (ffelex_file_fixed): Delay finishing statement until source line is registered with ffewhere, so INCLUDE processing picks up the info correctly. Okay to kill or use unknown line/col objects now. Handle HASH (#) lines. Reorder tests for insubstantial lines to put most frequent occurrences at top, for possible minor speedup. Some general consolidation of code. (ffelex_file_free): Handle HASH (#) lines. Okay to kill or use unknown line/col objects now. Some general consolidation of code. (ffelex_init_1): Detect HASH (#) lines. (ffelex_set_expecting_hollerith): Okay to kill or use unknown line/col objects now. * lex.h (FFELEX_typeHASH): New enum. * options-lang.h (-fident, -fno-ident): New options. * stw.c (ffestw_update): Okay to kill unknown line/col objects now. * target.h (FFETARGET_okREALQUAD, FFETARGET_okCOMPLEXDOUBLE, FFETARGET_okCOMPLEXQUAD): #define these appropriately. * top.c: Include flag.j wrapper, not flags.h directly. (ffe_is_ident_): New flag. (ffe_decode_option): Handle -fident and -fno-ident. (ffe_file): Replace obsolete ffewhere_file_(begin|end) with ffewhere_file_set. * top.h (ffe_is_ident_, ffe_is_ident, ffe_set_is_ident): New flag and access functions. * where.c, where.h: Remove all tracking of parent file. (ffewhere_file_begin, ffewhere_file_end): Delete these. (ffewhere_line_use): Make it work with unknown line object. Mon Jul 17 03:04:09 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_sym_transform_): Set DECL_IN_SYSTEM_HEADER flag for any local vars used as stmtfunc dummies or DATA implied-DO iter vars, so no -Wunused warnings are produced for them (a la f2c). (ffecom_init_0): Do "extern int xargc;" for IARGC() intrinsic. Warn if target machine not 32 bits, since g77 isn't yet working on them at all well. * expr.c (ffeexpr_sym_lhs_call_, ffeexpr_sym_lhs_data_, ffeexpr_sym_lhs_extfunc_, ffeexpr_sym_rhs_actualarg_, ffeexpr_sym_rhs_let_, ffeexpr_paren_rhs_let_): Don't gratuitously set attr bits that don't apply just to avoid null set meaning error; instead, use explicit error flag, and allow null attr set, to fix certain bugs discovered by looking at this code. * g77.c: Major changes to improve support for gcc long options, to make `g77 -v' report more useful info, and so on. Mon Jul 3 14:49:16 1995 Craig Burley (burley@gnu.ai.mit.edu) * DOC, com.c, intrin.h, intrin.c, intrin.def, target.h, top.c, top.h: Add new `unix' group of intrinsics, which includes the newly added ERF, ERFC, EXIT, plus even newer ABORT, DERF, DERFC, FLUSH, GETARG, GETENV, SIGNAL, and SYSTEM. Tue Jun 27 23:01:05 1995 Craig Burley (burley@gnu.ai.mit.edu) * bld.c, bld.h (ffebld_constant_pool, ffebld_constant_character_pool): Use a single macro (the former) to access the pool for allocating constants, instead of latter in public and FFEBLD_CONSTANT_POOL_ internally in bld.c (which was the only one that was correct before these changes). Add verification of integrity of certain heap-allocated areas. * com.c (ffecom_overlap_, ffecom_args_overlap_, ffecom_tree_canonize_ptr_, ffecom_tree_canonize_ref_): New functions to optimize calling COMPLEX and, someday, CHARACTER functions requiring additional argument to be passed. (ffecom_call_, ffecom_call_binop_, ffecom_expr_, ffecom_expr_intrinsic_): Change calling sequences to include more info on possible destination. (ffecom_expr_intrinsic_): Add ERF(), ERFC(), and EXIT() intrinsic code. (ffecom_sym_transform_): For assumed-size arrays, set high bound to highest possible value instead of low bound, to improve validity of overlap checking. (duplicate_decls): If olddecl and newdecl are the same, don't do any munging, just return affirmative. * expr.c: Change ffecom_constant_character_pool() to ffecom_constant_pool(). * info.c (ffeinfo_new): Compile this version if not being compiled by GNU C. * info.h (ffeinfo_new): Don't define macro if not being compiled by GNU C. * intrin.c, intrin.def: Add ERF(), ERFC(), and EXIT() intrinsics. (ffeintrin_check_exit_): New for EXIT() subroutine intrinsic. * malloc.c, malloc.h (malloc_verify_*): New functions to verify integrity of heap-storage areas. * stc.c (ffestc_R834, ffestc_R835): Handle possibility that an enclosing DO won't have a construct name even when the CYCLE/EXIT does (i.e. without dereferencing NULL). * target.c, target.h (ffetarget_verify_character1): New function to verify integrity of heap storage used to hold character constant. Thu Jun 22 15:36:39 1995 Howard Gordon (flash@super.org) * stp.h (ffestpVxtcodeIx): Fix typo in typedef for this. Mon May 29 15:22:31 1995 Craig Burley (burley@gnu.ai.mit.edu) * *: Make all sorts of changes to accommodate upcoming gcc-2.7.0. I didn't keep track of them, nor just when I made them, nor when I (much later, probably in early August 1995) modified them so they could properly handle both 2.7.0 and 2.6.x. * com.c (ffecom_expr_power_integer_): Don't expand_start_stmt_expr if transforming dummy args, because the back end cannot handle that (it's rejected by the gcc front end), just generate call to run-time library. Back out changes in 0.5.15 because more temporaries might be needed anyway (for COMPLEX**INTEGER). (ffecom_push_tempvar): Remove inhibitor. Around start_decl and finish_decl (in particular, arround expand_decl, which is called by them), push NULL_TREE into sequence_rtl_expr, an external published by gcc/function.c. This makes sure the temporary is truly in the function's context, not the inner context of a statement-valued expression. (I think the back end is inconsistent here, but am not interested in convincing the gbe maintainers about this now.) (pushdecl): Make sure that when pushing PARM_DECLs, nothing other than them are pushed, as happened for 0.5.15 and which, if done for other reasons not fixed here, might well indicate some other problem -- so crash if it happens. * equiv.c (ffeequiv_layout_local_): If the local equiv group has a non-nil COMMON field, it should mean that an error has occurred and been reported, so just trash the local equiv group and do nothing. * stc.c (ffestc_promote_sfdummy_): Set sfdummy arg state to UNDERSTOOD so above checking for duplicate args actually works, and so we don't crash later in pushdecl. * ste.c (ffeste_R1001): Set initial value only for VAR_DECLs, not for, e.g., LABEL_DECLs, which the FORMAT label can be if it was previously treated as an executable label. Sat May 20 01:53:53 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_sym_transform_): For adjustable arrays, pass high bound through variable_size in case its primaries are changed (dumb0.f, and this might also improve performance so it approaches f2c|gcc). Fri May 19 11:00:36 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.15 released. * com.c (ffecom_expr_power_integer_): Push temp vars before expanding a statement expression, since that seems to cause temp vars to be "forgotten" after the end of the expansion in the back end. Disallow more temp-var pushing during such an expansion, just in case. (ffecom_push_tempvar): Crash if a new variable needs to be pushed but cannot be at this point (should never happen). Wed May 17 12:26:16 1995 Craig Burley (burley@gnu.ai.mit.edu) * expr.c (ffeexpr_collapse_convert): Add code to convert LOGICAL to CHARACTER. Reject conversion of REAL or COMPLEX to CHARACTER entirely, as it cannot be supported with all configurations. * target.h, target.c (ffetarget_convert_character1_logical1): New function. Sun May 14 00:00:09 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_do_entry_, ffecom_gen_sfuncdef_, ffecom_start_progunit_, ffecom_sym_transform_, ffecom_init_0, start_function): Changes to have REAL external functions return same type as DOUBLE PRECISION external functions when -ff2c is in force; while at it, some code cleanups done. * stc.c (ffestc_R547_item_object): Disallow array declarator if one already exists for symbol. * ste.c (ffeste_R1227): Convert result variable to type of function result as seen by back end (e.g. for when REAL external function actually returns result as double). * target.h (FFETARGET_defaultFIXED_LINE_LENGTH): New macro for default for -ffixed-line-length-N option. * top.c (ffe_fixed_line_length_): Initialize this to new target.h macro instead of constant 72. Tue May 9 01:20:03 1995 Craig Burley (burley@gnu.ai.mit.edu) * lex.c (ffelex_send_token_): If sending CHARACTER token with null text field, put a single '\0' in it and set length/size fields to 0 (to fix 950508-0.f). (ffelex_image_char_): When setting ffelex_bad_line_ to TRUE, always "close" card image by appending a null char and setting ffelex_card_length_. As part of this, append useful text to identify the two kinds of problems that involve this. (ffelex_file_fixed): Reset ffelex_bad_line_ to FALSE after seeing a line with invalid first character (fixes 950508-1.f). If final nontab column is zero, assume tab seen in line. (ffelex_card_image_): Always make this array 8 characters longer than reflected by ffelex_card_size_. (ffelex_init_1): Get final nontab column info from top instead of assuming 72. * options-lang.h: Add -ffixed-line-length- prefix. * top.h: Add ffe_fixed_line_length() and _set_ version, plus corresponding extern. * top.c: Handle -ffixed-line-length- option prefix. Fri Apr 28 05:40:25 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.14 released. * Make-lang.in: Add assert.j. * Makefile.in: Add assert.j. * assert.j: New file. Thu Apr 27 16:24:22 1995 Craig Burley (burley@gnu.ai.mit.edu) * bad.h (ffebad_severity): New function. * bad.c (ffebad_severity): New function. * bad.def (FFEBAD_OPEN_INCLUDE): Change severity from SEVERE to FATAL, since processing continues, and that seems fine. * com.c: Add facility to handle -I. (ffecom_file, ffecom_close_include, ffecom_open_include, ffecom_decode_include_option): New global functions for -I. (ffecom_file_, ffecom_initialize_char_syntax_, ffecom_close_include_, ffecom_decode_include_option_, ffecom_open_include_, append_include_chain, open_include_file, print_containing_files, read_filename_string, file_name_map, savestring): New internal functions for -I. * compilers.h: Pass -I flag(s) to f771 (via "%{I*}"). * lex.c (ffelex_include_): Call ffecom_close_include to close include file, for its tracking needs for -I, instead of using fclose. * options-lang.h: Add -I prefix. * parse.c (yyparse): Call ffecom_file for main input file, so -I handling works (diagnostics). * std.c (ffestd_S3P4): Have ffecom_open_include handle opening and diagnosing errors with INCLUDE files. * ste.c (ffeste_begin_iterdo_): Use correct algorithm for calculating # of iterations -- mathematically similar but computationally different algorithm was not handling cases like "DO I=6,5,2" correctly, because (5-6)/2+1 => 1, not 0. * top.c (ffe_decode_option): Allow -I, restructure a bit for clarity and, maybe, speed. Mon Apr 17 13:31:11 1995 Craig Burley (burley@gnu.ai.mit.edu) * g77.c: Remove -lc, turns out not all systems has it, but leave other changes in for clarity of code. Sun Apr 16 21:50:33 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_expr_): Implement ARRAY_EXPR as INDIRECT_REF of appropriate PLUS_EXPRs of ptr_to_expr of array, to see if this generates better code. (Conditional on FFECOM_FASTER_ARRAY_REFS.) Sun Apr 16 00:22:48 1995 Craig Burley (burley@gnu.ai.mit.edu) * Make-lang.in (F77_SRCS): Remove g77.c, since it doesn't contribute to building f771. * Makefile.in (dircheck): Remove/replace with f/Makefile, because phony targets that are referenced in other real targets get run when those targets are specified, which is a waste of time (e.g. when rebuilding and only g77.c has changed, f771 was being linked anyway). * g77.c: Include -lc between -lf2c and -lm throughout. * implic.c (ffeimplic_establish_symbol): If -Wimplicit, warn if implicit type given to symbol. * lex.c (ffelex_include_): Don't gratuitously increment line number here. * top.h, top.c (ffe_is_warn_implicit_): New global variable and related access macros. (ffe_decode_option): Handle -W options, including -Wall and -Wimplicit. * where.c (ffewhere_line_new): Don't muck with root line (was crashing on null input since lexer changes over the past week or so). Thu Apr 13 16:48:30 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_init_0): Register built-in functions for cos, sin, and sqrt. (ffecom_tree_fun_type_double): New variable. (ffecom_expr_intrinsic_): Update f2c input and output files to latest version of f2c (no important g77-related changes noted, just bug fixes to f2c and such). (builtin_function): New function from c-decl.c. * com-rt.def: Refer to built-in functions for cos, sin, and sqrt. Thu Apr 13 10:25:09 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_expr_intrinsic_): Convert 0. to appropriate type to keep DCMPLX(I) from crashing the compiler. (ffecom_expr_): Don't convert result from ffecom_tree_divide_. (ffecom_tree_divide_): Add tree_type argument, have all callers pass one, and don't convert right-hand operand to it (this is to make this new function work as much like the old in-line code used in ffecom_expr_ as possible). * lex.c: Maintain lineno and input_filename the way the gcc lexer does. * std.c (ffestd_exec_end): Save and restore lineno and input_filename around the second pass, which sets them appropriately for each saved statement. Wed Apr 12 09:44:45 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_expr_power_integer_): New function. (ffecom_expr_): Call new function for power op with integer second argument, for generating better code. Also replace divide code with call to new ffecom_tree_divide_ function. Canonicalize calls to ffecom_truth_value(_invert). (ffecom_tree_divide_): New function. Wed Apr 5 14:15:44 1995 Craig Burley (burley@gnu.ai.mit.edu) * lex.c: Change to allocate text for tokens only when actually needed, which should speed compilation up somewhat. Change to allow INCLUDE at any point where a statement can end, i.e. in ffelex_finish_statement_ or when a SEMICOLON token is sent. Remove some old, obsolete code. Clean up layout of entire file to improve formatting, readability, etc. (ffelex_set_expecting_hollerith): Remove include argument. Fri Mar 31 23:19:08 1995 Craig Burley (burley@gnu.ai.mit.edu) * bad.h, bad.c (ffebad_start_msg, ffebad_start_msg_lex): New functions to generate arbitrary messages. (FFEBAD_severityPEDANTIC): New severity, to correspond to toplev's pedwarn() function. * lex.c (ffelex_backslash_): New function to implement backslash processing. (ffelex_file_fixed, ffelex_file_free): Implement new backslash processing. * std.c (ffestd_R1001dump_): Don't assume CHARACTER and HOLLERITH tokens stop at '\0' characters, now that backslash processing is supported -- use their advertised lengths instead, and double up the '\002' character for libf2c. Mon Mar 27 17:10:33 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_init_local_zero_): Implement -finit-local-zero. (ffecom_sym_transform_): Same. (ffecom_transform_equiv_): Same. * options-lang.h: Add -f(no-)(init-local-zero,backslash,ugly-init). * stb.c (ffestb_V020): Reject "TYPEblah(...", which might be an array assignment. * target.h, top.h, top.c: Implement -finit-local-zero. Fri Mar 24 19:56:22 1995 Craig Burley (burley@gnu.ai.mit.edu) * Make-lang.in, Makefile.in: Remove conf-proj(.in) and proj.h(.in) rules, plus related config.log, config.cache, and config.status stuff. * com.c (ffecom_init_0): Change messages when atof(), bsearch(), or strtoul() do not work as expected in the start-up test. * conf-proj, conf-proj.in: Delete. * lex.c (ffelex_file_fixed): Allow f2c's '&' in column 1 to mean continuation line. * options-lang.h: New file, #include'd by ../toplev.c. * proj.h.in: Rename back to proj.h. * proj.h (LAME_ASSERT): Remove. (LAME_STDIO): Remove. (NO_STDDEF): Remove. (NO_STDLIB): Remove. (NO_BSEARCH): Remove auto detection, rename to !FFEPROJ_BSEARCH. (NO_STRTOUL): Remove auto detection, rename to !FFEPROJ_STRTOUL. (USE_HOST_LIMITS): Remove (maybe still needed by stand-alone?). (STR, STRX): Do only ANSI C definitions. Mon Mar 13 10:46:13 1995 Craig Burley (burley@gnu.ai.mit.edu) * BUGS: Add item about g77 requiring gcc to compile it. * NEWS: New file listing user-visible changes in the release. * PROJECTS: Update to include a new item or two, and modify or delete items that are addressed in this or previous releases. * bad.c (ffebad_finish): Don't crash if missing string &c, just substitute obviously distressed string "[REPORT BUG!!]" for cases where the message/caller are fudgy. * bad.def: Clean up error messages in a major way, add new ones for use by changes in target.c. * com.c (ffecom_expr_): Handle opANY in opCONVERT. (ffecom_let_char_): Disregard destinations with ERROR_MARK. (ffecom_1, ffecom_1_fn, ffecom_2, ffecom_2s, ffecom_3, ffecom_3s, &c): Check all inputs for error_mark_node. (ffecom_start_progunit_): Don't transform all symbols in BLOCK DATA, since it never executes, and it is silly to, e.g., generate all the structures for NAMELIST. (ffecom_char_length_expr_): Rename to ffecom_intrinsic_len_. (ffecom_intrinsic_ichar_): New function to handle ICHAR of arbitrary expression with possible 0-length operands. (ffecom_expr_intrinsic_): Use ffecom_intrinsic_char_. For MVBITS, set tree_type to void_type_node. (ffecom_start_progunit_): Name master function for entry points after primary entry point so users can easily guess it while debugging. (ffecom_arg_ptr_to_expr): Change treatment of Hollerith, Typeless, and %DESCR. (ffecom_expr_): Change treatment of Hollerith. * data.c (ffedata_gather_): Handle opANY in opCONVERT. * expr.c (ffeexpr_token_apostrophe_): Issue FFEBAD_NULL_CHAR_CONST warning as necessary. (ffeexpr_token_name_rhs_): Set context for args to intrinsic so that assignment-like concatenation is allowed for ICHAR(), IACHAR(), and LEN() intrinsics. (ffeexpr_reduced_*_): Say "an array" instead of "an entity" in diagnostics, since it's more informative. (ffeexpr_finished_): For many contexts, check for null expression and array before trying to do a conversion, to avoid redundant diagnostics. * g77.1: Fix typo for preprocessed suffix (.F, not .f). * global.c (ffeglobal_init_common): Warn if initializing blank common. (ffeglobal_pad_common): Enable code to warn if initial padding needed. (ffeglobal_size_common): Complain if enlarging already- initialized common, since it won't work right anyway. * intrin.c: Add IMAG() intrinsic. (ffeintrin_check_loc_): Allow opSUBSTR in LOC(). * intrin.def: Add IMAG() intrinsic. * lex.c: Don't report FFEBAD_NULL_CHAR_CONST errors. * sta.c, sta.h, stb.c: Changes to clean up error messages (see bad.def). * stb.c (ffestb_R100113_): Issue FFEBAD_NULL_CHAR_CONST warning as necessary. * stc.c (ffestc_shriek_do_): Don't try to reference doref_line stuff in ANY case, since it won't be valid. (ffestc_R1227): Allow RETURN in main program unit, with appropriate warnings/errors. (ffestc_subr_format_): Array of any type is a CHAREXPR (F77 C5). * ste.c (ffeste_begin_doiter_): Couple of fixes to accurately determine if loop never executes. * target.c (ffetarget_convert_*_hollerith_): Append spaces, not zeros, to follow F77 Appendix C, and to warn when truncation of non-blanks done.

Sun Mar 5 18:46:42 1995 Craig Burley (burley@gnu.ai.mit.edu) * BUGS: Clarify that constant handling would also fix lack of adequate IEEE-754/854 support to some degree, and typeless and non-decimal constants. * com.c (ffecom_type_permanent_copy_): Comment out to avoid warnings. (duplicate_decls): New function a la gcc/c-decl.c. (pushdecl): Use duplicate_decls to decide whether to return existing decl or new one, instead of always returning existing decl. (ffecom_expr_): opPERCENT_LOC now supports CHARACTER arguments. (ffecom_init_0): Give f2c I/O code 0 for basictypeANY/kindtypeANY. (ffecom_sym_transform_): For adjustable arrays, pass low bound through variable_size in case its primaries are changed (950302-1.f). * com.h: More decls that belong in tree.h &c. * data.c (ffedata_eval_integer1_): Fix opPAREN case to not treat value of expression as an error code. * expr.c (ffeexpr_finished_): Allow opSUBSTR in contextLOC case. * proj.c: Add "const" as appropriate. Mon Feb 27 10:04:03 1995 Craig Burley (burley@gnu.ai.mit.edu) * bad.def (FFEBAD_BAD_SUBSTR): Fix bad grammar in message. Fri Feb 24 16:21:31 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.13 released. * INSTALL: Warn that f/zzz.o will compare differently between stages, since it puts the __TIME__ macro into a string. * com.c (ffecom_sym_transform_): Transform kindFUNCTION/whereDUMMY to pointer-to-function, not function. (ffecom_expr_): Use ffecom_arg_ptr_to_expr instead of ffecom_char_args_ to handle comparison between CHARACTER types, so either operand can be a CONCATENATE. (ffecom_transform_common_): Set size of initialized common area to global (largest-known) size, even though size of init might be smaller. * equiv.c (ffeequiv_offset_): Check symbol info for ANY. * expr.c (ffeexpr_find_close_paren_, ffeexpr_nil_*): New functions to handle following the contour of a rejected expression, so statements like "PRINT(I,I,I)=0" don't cause the PRINT statement code to get the second passed back to it as if there was a missing close-paren before it, the comma causing the PRINT code to confirm the statement, resulting in an ambiguity vis-a-vis the let statement code. Use the new ffecom_find_close_paren_ handler when an expected close-paren is missing. (ffeexpr_isdigits_): New function, use in all places that currently use isdigit in repetitive code. (ffeexpr_collapse_symter): Collapse to ANY if init-expr is ANY, so as to avoid having symbol get "transformed" if used to dimension an array. (ffeexpr_token_real_, ffeexpr_token_number_real_): Don't issue diagnostic about exponent, since it'll be passed along the handler path, resulting in a diagnostic anyway. (ffeexpr_token_apos_char_): Use consistent handler path regardless of whether diagnostics inhibited. (ffeexpr_token_name_apos_name_): Skip past closing quote/apos even if not a match or other diagnostic issued. (ffeexpr_sym_impdoitem_): Exec-transition local SEEN symbol. * lex.c (ffelex_image_char_): Set ffelex_saw_tab_ if TAB seen, not if anything other than TAB seen! * stc.c (ffestc_R537_item): If source is ANY but dest isn't, set dest symbol's init expr to ANY. (ffestc_R501_attrib, ffestc_R522, ffestc_R522start): Complain about conflict between "SAVE" by itself and other uses of SAVE only in pedantic mode. * ste.c (ffeste_R1212): Fix loop over labels to always increment caseno, to avoid pushcase returning 2 for duplicate values when one of the labels is invalid. Thu Feb 23 12:42:04 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.12 released. * Make-lang.in (f77.install-common): Add "else true;" before outer "fi" per Makefile.in patch. * Makefile.in (dircheck): Add "else true;" before "fi" per patch from chs1pm@surrey.ac.uk. * com.c (ffecom_push_tempvar): If type desired is ERROR_MARK, return error_mark_node, to avoid crash that results from making a VAR_DECL with error_mark_node as its type. * ste.c (ffeste_begin_iterdo_): Convert itercount to INTEGER anytime calculation of number of iterations ends up with type other than INTEGER (e.g. DOUBLE PRECISION, REAL). Thu Feb 23 02:48:38 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.11 released. * DOC: Explain -fugly-args. * bad.def (FFEBAD_ACTUALARG): Explain -fugly-args and how to rewrite code to not require it. * com.c (ffecom_vardesc_): Handle negative type code, just in case. (ffecom_arg_ptr_to_expr): Let ffecom_expr handle hollerith and typeless constants (move code to ffecom_constantunion). (ffecom_constantunion): Handle hollerith and typeless constants. * expr.c (ffecom_finished_): Check -fugly-args in actual-arg context where hollerith/typeless provided. * intrin.def (FFEINTRIN_genDFLOAT): Add FFEINTRIN_specDFLOAT. (FFEINTRIN_specDFLOAT): Add as f2c intrinsic. * target.h (ffetarget_convert_real[12]_integer, ffetarget_convert_complex[12]_integer): Pass -1 for high integer value if low part is negative. (FFETARGET_defaultIS_UGLY_ARGS): New macro. * top.c (ffe_is_ugly_args_): New variable. (ffe_decode_option): Handle -fugly-args and -fno-ugly-args. * top.h (ffe_is_ugly_args_, ffe_is_ugly_args(), ffe_set_is_ugly_args()): New variable and macros. Thu Feb 23 02:48:38 1995 Pedro A M Vazquez (vazquez@iqm.unicamp.br) * g77.c (sys_errlist): Use const for __FreeBSD__ systems as well. Wed Feb 22 13:33:43 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.10 released. * CREDITS: Add Rick Niles. * INSTALL: Note how to get around lack of makeinfo. * Make-lang.in (f/proj.h): Remove # comment. * Makefile.in (f/proj.h): Remove # comment. * com.c (ffecom_expr_): Simplify opFUNCREF/opSUBRREF conversion. (ffecom_sym_transform_): For whereGLOBAL and whereDUMMY kindFUNCTION, use ffecom_tree_fun_type[][] only for non-constant (non-statement-function) f2c functions. (ffecom_init_0): ffecom_tree_fun_type[][] and _ptr_to_*_* are really f2c-interface arrays, so use base type void for COMPLEX (like CHARACTER). Tue Feb 21 19:01:18 1995 Dave Love * Make-lang.in (f77.install-common): Expurgate the test for and possible installation of f2c in line with elsewhere. Seems to have been missing a semicolon anyhow! Tue Feb 21 11:45:25 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.9 released. * Make-lang.in (f/proj.h): touch file to register update, because the previous commands won't necessarily modify it. * Makefile.in (f/proj.h): touch file to register update, because the previous commands won't necessarily modify it. * Makefile.in (f/str-*.h, f/str-*.j): Explicitly specify output file names, so these targets go in build, not source, directory. * bits.c, bits.h: Switch to valid ANSI C replacement for ARRAY_ZERO. * com.c (ffecom_expr_): Add assignp arg to support ASSIGN better. If assignp is TRUE, use different tree for FFEBLD_opSYMTER case. (ffecom_sym_transform_assign_): New function. (ffecom_expr_assign): New function. (ffecom_expr_assign_w): New function. * com.c (ffecom_f2c_make_type_): Do make_signed_type instead of make_unsigned_type throughout. * com.c (ffecom_finish_symbol_transform_): Expand scope of commented-out code to probably produce faster compiler code. * com.c (ffecom_gen_sfuncdef_): Push/pop calltemps so COMPLEX works right. Remove obsolete comment. * com.c (ffecom_start_progunit_): If non-multi alt-entry COMPLEX function, primary (static) entry point returns result directory, not via extra arg -- to agree with ffecom_return_expr and others. Pretransform all symbols so statement functions are defined before any code emitted. * com.c (ffecom_finish_progunit): Don't posttransform all symbols here -- pretransform them instead. * com.c (ffecom_init_0): Don't warn about possible ASSIGN crash, as this shouldn't happen now. * com.c (ffecom_push_tempvar): Fix to handle temp vars pushed while context is a statement (nested) function, and add appropriate commentary. * com.c (ffecom_return_expr): Check TREE_USED to determine where return value is unset. * com.h (struct _ffecom_symbol_): Add note about length_tree now being used to keep tree for ASSIGN version of symbol. * com.h (ffecom_expr_assign, ffecom_expr_assign_rw): New decls. (error): Add this prototype for back-end function. * fini.c (main): Grab input, output, and include names directly off the command line instead of making the latter two out of the first. * lex.c: Improve tab handling for both fixed and free source forms, and ignore carriage-returns on input, while generally improving the code. ffelex_handle_tab_ has been renamed and reinvented as ffelex_image_char_, among other things. * malloc.c, malloc.h: Switch to valid ANSI C replacement for ARRAY_ZERO, and kill the full number of bytes in pools and areas. * proj.h.in (ARRAY_ZERO, ARRAY_ZERO_SIZE): Remove. * ste.c (ffeste_io_cilist_, ffeste_io_icilist_, ffeste_R838, ffeste_R839): Issue diagnostic if a too-narrow variable used in an ASSIGN context despite changes to this code and code in com.c. * where.c, where.h: Switch to valid ANSI C replacement for ARRAY_ZERO. Fri Feb 17 03:35:19 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.8 released. * INSTALL: In quick-build case, list g77 target first so g77 gets installed. Also, explain that gcc gets built and installed as well, even though this isn't really what we want (and maybe we'll find a way around this someday). Fri Feb 17 02:35:41 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.7 released. * Makefile.in (CONFIG_H, HCONFIG_H, TCONFIG_H, TM_H): Remove ../ prefix in front of .h files, since they're in the cd. Fri Feb 17 01:50:48 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.6 released. Thu Feb 16 20:26:54 1995 Craig Burley (burley@gnu.ai.mit.edu) * ../README.g77: Remove description of g77 as "not-yet-published". * CREDITS: More changes. * Make-lang.in (G77STAGESTUFF): Remove cktyps stuff. * Makefile.in (CONFIG_H, HCONFIG_H, TCONFIG_H, TM_H): Don't prefix gcc dir with $(srcdir) since these don't live there, they are created in the build dir by gcc's configure. Add a note explaining what these macros are about. Update dependencies via deps-kinda. * README.NEXTSTEP: Credit Toon, and per his request, add his email address. * com.h (FFECOM_DETERMINE_TYPES): #include "config.j". * config.j, convert.j, flags.j, hconfig.j, rtl.j, tconfig.j, tm.j, tree.j: Don't #include if already done. * convert.j: #include "tree.j" first, as convert.h clearly depends on trees being defined. * rtl.j: #include "config.j" first, since there's some stuff in rtl.h that assumes it has been #included. * tree.j: #include "config.j" first, or real.h makes inconsistent decision about return type of ereal_atof, leading to bugs, and because tree.h/real.h assume config.h already included. Wed Feb 15 14:40:20 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.5 released. * Copyright notices updated to be FSF-style. * INSTALL: Some more clarification regarding building just f77. * Make-lang.in (F77_SRCS): Update wrt changing some .h to .j. (install-libf77): Fix typo in new parenthetical note. * Makefile.in (f/*.o): Update. (CONFIG_H, CONVERT_H, FLAGS_H, GLIMITS_H, HCONFIG_H, RTL_H, TCONFIG_H, TM_H, TREE_H): Update/new symbols. (deps-kinda): More fixes wrt changing some .h to .j. Document and explain this rule a bit better. Accommodate changes in output of gcc -MM. * *.h, *.c: Change #include's so proj.h not assumed to #include malloc.h or config.h (now config.j), and so new .j files are used instead of old .h ones. * com.c (ffecom_init_0): Use FLOAT_TYPE_SIZE for f2c's TYLONG/TYLOGICAL type codes, to get g77 working on Alpha. * com.h: Make all f2c-related integral types "int", not "long int". * config.j, convert.j, flags.j, glimits.j, hconfig.j, rtl.j, tconfig.j, tm.j, tree.j: New files wrapping around gbe .h files. * config.h, convert.h, flags.h, glimits.h, hconfig.h, rtl.h, tconfig.h, tm.h, tree.h: Deleted so new .j files can #include the gbe files directly, instead of using "../", and thus do better with various kinds of builds. * proj.h: Delete unused NO_STDDEF and related stuff. Tue Feb 14 08:28:08 1995 Craig Burley (burley@gnu.ai.mit.edu) * BUGS: Remove item #12, cross-compiling & autoconf scripts reportedly expected to work properly (according to d.love). * INSTALL: Add explanation of d.love's patch to config-lang.in. Add explanation of how to install just g77 when gcc already installed. Add note about usability of "-Wall". Add note about bug- reporting. * Make-lang.in ($(srcdir)/f/conf-proj): Add comment about why conf-proj.out. (install-libf77): Echo parenthetical note to user about how to do just the (aborted) libf2c installation. (deps-kinda): Update to work with new configuration/build stuff. * bad.c (ffebad_finish): Put capitalized "warning:" &c message as prefix on any diagnostic without pointers into source. * bad.def (FFEBAD_TOO_BIG_INIT): Add this warning message. * config-lang.in: Add Dave Love's patch to catch case where back-end patches not applied and abort configuration. * data.c (ffedata_gather_, ffedata_value_): Warn when about to initialize a large aggregate area, due to design flaw resulting in too much time/space used to handle such cases. Use COMMON area name, and first notice of symbol, for multiple- initialization diagnostic, instead of member symbol and unknown location. (FFEDATA_sizeTOO_BIG_INIT_): New macro per above. Mon Feb 13 13:54:26 1995 Dave Love * Make-lang.in (F77_SRCS): Use $(srcdir)/f/proj.h.in, not $(srcdir)/f/proj.h for build outside srcdir. Sun Feb 12 13:37:11 1995 Craig Burley (burley@gnu.ai.mit.edu) * ../README.g77: Clarify procedures for unpacking, add asterisks to mark important things the user must do. * Fix dates in/add dates to ../README.g77, BUGS, CREDITS, DOC, INSTALL, PROJECTS, README. Sun Feb 12 00:26:10 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.4 released. * Make-lang.in (f/proj.h): Reproduce this rule here from Makefile.in. ($(srcdir)/f/conf-proj): Put autoconf's stdout in temp file conf-proj.out, then mv to conf-proj only if successful, so conf-proj not touched if autoconf not installed. * Makefile.in ($(srcdir)/conf-proj): See Make-lang.in's similar rule. Sat Feb 11 20:56:02 1995 Craig Burley (burley@gnu.ai.mit.edu) * BUGS: Clarify some bugs. * DOC: Many improvements and fixes. * README: Move bulk of text, edited, to ../README.g77, and replace with pointer to that file. * com.c (ffecom_init_0): Comment out warning about sizeof(ftnlen) as per ste.c change. Add text about ASSIGN to help user understand what is being warned about. * conf-proj.in: Fix typos in comments. * proj.h.in: Add ARRAY_ZERO_SIZE to parallel malloc.h's version, in case it proves to be needed. * ste.c: Comment out assertions requiring sizeof(ftnlen) >= sizeof(char *), in the hopes that overflow will never happen. (ffeste_R838): Change assertion to fatal() with at least partially helpful message. Sat Feb 11 12:38:00 1995 Craig Burley (burley@gnu.ai.mit.edu) * com.c (ffecom_vardesc_): Crash if typecode is -1. * ste.c (ffeste_io_dolio_): Crash if typecode is -1. Sat Feb 11 09:51:57 1995 Craig Burley (burley@gnu.ai.mit.edu) * ste.c: In I/O code tests for item arrayness, sort of revert to much earlier code that tests original exp, but also check in newer way just in case. Newer way alone treated FOO(1:40) as an array, not sure why older way alone didn't work, but I think maybe it was when diagnosed code was involved, and since there are now checks for error_mark_node, maybe the old way alone would work. But better to be safe; both original ffebld exp _and_ the transformed tree must indicate an array for the size-determination code to be used, else just 1/2 elements assumed. And this text is for EMACS: (foo at bar). Fri Feb 10 11:05:50 1995 Craig Burley (burley@gnu.ai.mit.edu) * ste.c: In many cases, surround statement-expansion code with ffecom_push_calltemps () and ffecom_pop_calltemps () so COMPLEX-returning functions can have temporaries pushed in "auto-pop" mode and have them auto-popped at the end of the statement. Wed Feb 8 14:35:10 1995 Dave Love * runtime/f2c.h.in (ftnlen, ftnint): Make same size as integer. * runtime/libI77/err.c (f_init): Thinko in MISSING_FILE_ELEMS conditional. * runtime/libI77/wrtfmt.c (mv_cur): Likewise. * runtime/libI77/wsfe.c (x_putc): Likewise. * runtime/libF77/signal_.c (signal_): Return 0 (this is a subroutine). * Makefile.in (f/proj.h): Depend on com.h. * Make-lang.in (include/f2c.h): Likewise (and proj.h). (install-libf77): Also install f2c.h. * runtime/libI77/Makefile.in (*.o): Add f2c.h dependency. * runtime/libF77/Makefile.in: Likewise. Wed Feb 8 13:56:47 1995 Craig Burley (burley@gnu.ai.mit.edu) * stc.c (ffestc_R501_item): Don't reset kind/where to NONE when setting basictype/kindtype info for symbol, or especially its function/result twin, because kind/where might not be NONE. Tue Feb 7 14:47:26 1995 Dave Love * Make-lang.in (include/f2c.h:): Set shell variable src more robustly (independent of whether srcdir is relative or absolute). * Makefile.in (f/proj.h:): Likewise. * conf-proj.in: Check need for LAME_ASSERT. Fix indentation in check for LAME_STDIO (cosmetic only with ANSI C). * com.h: Extra ...SIZE stuff taken from com.c. * com.c (FFECOM_DETERMINE_TYPES): Define before including com.h. (BITS_PER_WORD etc.) Remove and use conditional definitions to com.h. * runtime/configure.in: #define FFECOM_DETERMINE_TYPES for com.h in f2c type determination. * tm.h: Remove (at least pro tem) because of relative path and use top-level one. * Make-lang.in (include/f2c.h:): Set shell variable src more robustly (independent of whether srcdir is relative or absolute). * Makefile.in (f/proj.h:): Likewise. Mon Feb 6 19:58:32 1995 Dave Love * g77.c (append_arg): Use K&R declaration for, e.g. SunOS4 build. Fri Feb 3 20:33:14 1995 Craig Burley (burley@gnu.ai.mit.edu) * g77.c (main): Treat -l like filename in terms of -x handling. Rewrite arglist mechanism for ease of maintenance. Make sure every -lf2c is followed by -lm and vice versa. * Make-lang.in: Put complete list of sources in F77_SRCS def so changing a .h file, for example, causes rebuild. * Makefile.in: Change test for nextstep to m68k-next-nextstep* so all versions of nextstep on m68k get the necessary flag. Fri Feb 3 19:10:32 1995 Dave Love * INSTALL: Note about possible conflict with existing libf2c.a and f2c.h. * Make-lang.in (f77.distclean): Tidy and move deletion of f/config.cache to mostlyclean. (install-libf77): Test for $(libdir)/libf2c.* and barf if found unless F2CLIBOK defined. * runtime/Makefile.in (all): Change path to include directory (and elsewhere). (INCLUDES): Remove (unused/misleading). (distclean): Include f2c.h. (clean): Include config.cache. * runtime/libF77/Makefile.in (.SUFFIXES): Correct typo. (ALL_CFLAGS) Fix up include search path to find f2c.h in top level includes always. (all): Depend on f2c.h. * runtime/libI77/Makefile.in (.SUFFIXES): Likewise. Thu Feb 2 17:17:06 1995 Dave Love * INSTALL: Note about --srcdir and GNU make. * runtime/f2c.h.in (Pad_UDread, ALWAYS_FLUSH): Reomve the #defines per below. * runtime/configure.in (Pad_UDread, ALWAYS_FLUSH): Define these here, not in f2c.h as they'r eonly relevant for building. * runtime/configure: Regenerated. * config-lang.in: Warn about using GNU make outside source tree since I can't get Irix5 or SunOS4 makes to work in this case. * Makefile.in (VPATH): Don't set it here. (srcdir): Make it the normal `.' (overridden) at top level. (all.indirect): New dependency `dircheck'. (f771): Likewise (dircheck): New target for foolproofing. (f/proj.h:): Change finding source. (CONFIG_H): Don't use this as the relative path in the include loses f builddir != srcdir. * config.h: Remove per CONFIG_H change above. * Make-lang.in (F77_FLAGS_TO_PASS): Remove GCC_FOR_TARGET. (f771:): Pass VPATH, srcdir to sub-make. (f/Makefile:): New target. (stmp-int-hdrs): new variable for cheating build. (f77-runtime:): Alter GCC_FOR_TARGET treatment. (include/f2c.h f/runtime/Makefile:) Likewise. (f77-runtime-unsafe:): New (cheating) target. Thu Feb 2 12:09:51 1995 Craig Burley (burley@gnu.ai.mit.edu) * BUGS: Update regarding losing EQUIVALENCE members in -g, and regarding RS/6000 problems in the back end. * CREDITS: Make some changes as requested. * com.c (ffecom_member_trunk_): Remove unused static variable. (ffecom_finish_symbol_transform_): Improve comments. (ffecom_let_char_): Fix size of temp address-type var.

Comment-out use of ffecom_member_phase2_, until problems with back end fixed. (ffecom_push_tempvar): Fix assertion to not crash okay code. * com.h: Remove old, commented-out code. Add prototype for warning() in back end. * ste.c (ffeste_io_dofio_, ffeste_io_dolio_, ffeste_io_douio_, ffeste_io_icilist_): Check correct type of variable for arrayness. Sun Jan 29 14:41:42 1995 Dave Love * BUGS: Remove references to my configure bugs; add another. * runtime/Makefile.in (AR_FLAGS): Provide default value. * runtime/f2c.h.in (integer, logical): Take typedefs from F2C_INTEGER configuration parameter again. (NON_UNIX_STDIO): don't define it. * runtime/configure.in: Bring type checks for f2c.h in line with com.h. (MISSING_FILE_ELEMS): New variable to determine whether the relevant elements of the FILE struct exist, independent of NON_UNIX_STDIO. * runtime/libI77/{err,wrtfmt,wsfe}.c (MISSING_FILE_ELEMS): Use new parameter. * config-lang.in: Comment out more of f2c rules (c.f. Make-lang.in). (This stuff is relevant iff you gave configure --enable-f2c.) Create f/runtime directory tree iff not building in source directory. * Makefile.in (srcdir): Append slash so we get the right value when not building in the source directory. This is a consequence of not building the `f' sources in `f'. (VPATH): Override configure's value for reasons above. (f/proj.h f/conf-proj): New rules to build proj.h by autoconfiguration. * proj.h: Rename to proj.h.in for autoconfiguration. * proj.h.in: New as above. * conf-proj conf-proj.in: New files for autoconfiguration. * Make-lang.in (include/f2c.h f/runtime/Makefile:): Change the order of setting the sh variables so that the right GCC_FOR_TARGET is used. (f77.*clean:) Add products of new configuration files and make sure all the *clean targets do something (unlike the ones in cp/Make-lange.in). * com.h (FFECOM_f2cINTEGER, FFECOM_f2cLOGICAL): Define as long or int appropriately to ensure sizeof(real) == sizeof(integer). * PROJECTS: Library section. * runtime/libI77/endfile.c: Don't #include sys/types.h conditional on NON_UNIX_STDIO since rawio.h needs size_t. * runtime/libI77/uio.c: #include for size_t if not KR_headers. Wed Jan 25 03:31:51 1995 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.3 released. * INSTALL: Revise. * Make-lang.in: Comment out rules for building f2c itself (f/f2c/). * README: Revise. * com.c (ffecom_init_0): Warn if ftnlen or INTEGER not big enough to hold a char *. * gbe/2.6.2.diff: Update. Mon Jan 23 17:10:49 1995 Craig Burley (burley@gnu.ai.mit.edu) * TODO: Remove. BUGS: New file. PROJECTS: New file. CREDITS: New file. * cktyps*: Remove. Make-lang.in: Remove cktyps stuff. Makefile.in: Remove cktyps stuff. * DOC: Add info on changes for 0.5.3. * bad.c: Put "warning:" &c on diagnostic messages. Don't output informational messages if warnings disabled. Thu Jan 19 12:38:13 1995 Craig Burley (burley@gnu.ai.mit.edu) * g77.c: Avoid putting out useless "-xnone -xf77" pairs so larger command lines can be accommodated. Recognize both `-xlang' and `-x lang'. Recognize `-xnone' and `-x none' to mean what it does, instead of treating "none" as any other language. Some minor, slight improvements in the way args are handled (hopefully for clearer, more maintainable code), including consistency checks on arg count just in case. Wed Jan 18 16:41:57 1995 Craig Burley (burley@gnu.ai.mit.edu) * DOC: Explain -fautomatic better. * INSTALL: Describe libf2c.a better. * Make-lang.in, Makefile.in: Build f771 &c with gcc/ as cd instead of gcc/f/ so debugging info is better (source file tracking). Add new source file type.c. * Makefile.in: For nextstep3, link f771 with -segaddr __DATA 6000000. Fix typo. Change deps-kinda target to handle building from gcc/. Update dependencies. * bld-op.def, bld.h, bld.c: Remove opBACKEND and all related stuff. Remove consistency tests that cause compiler warnings. * cktyps.c: Remove all typing checking. * com-rt.def: Change all rttypeFLOAT_ intrinsics to rttypeDOUBLE_, to precisely match how they're declared in libf2c. * com.h, com.c: Revise to more elegantly track related stuff in the version of f2c.h used to build libf2c. * com.c: Increase FFECOM_sizeMAXSTACKITEM, and if 0 or undefined when checked to determine where to put entity, treat as infinite. Rewrite temporary mechanism to be based on trees instead of ffeinfo stuff, and make it much simpler. Change interface accordingly. Fixes to better track types of things, make appropriate conversions, etc. E.g. when making an arg for a libf2c function, make sure it's of the right type (such as ftnlen). Delete opBACKEND transformation code. (ffecom_init_0): Smoother initialization of types, especially paying attention to using consistent rules for making INTEGER, REAL, DOUBLE PRECISION, etc., and for deciding their "*N" and kind values that will work across all g77 platforms. No longer require per-target configuration info in target.h or config/*/*; use new type module to store size, alignment. (ffecom_member_phase2): Declare COMMON/EQUIVALENCE group members so debugger sees them. (ffecom_finish_progunit): Transform all symbols in program unit, so -g will show they all exist. * expr.c (ffeexpr_collapse_substr): Handle strange substring range values. * info.h, info.c: Provide connection to new type module. Remove tests that yield compiler warnings. * intrin.c (ffeintrin_is_intrinsic): Properly handle deleted intrinsic. * lex.c (ffelex_file_fixed): Remove redundant/buggy code. * stc.c (ffestc_kindtype_kind_, ffestc_kindtype_star_): Replace boring switch stmt with simple call to new type module. This sort of thing is a reason to get up in the morning. * ste.c: Update to handle new interface for ffecom_push/pop_tempvar. Fixes to better track types of things. Fixes to not crash for certain diagnosed constructs. (ffeste_begin_iterdo_): Check only constants for overflow to avoid spurious diagnostics. Don't convert larger integer (say, INTEGER*8) to canonical integer for iteration count. * stw.h: Track DO iteration count temporary variable. * symbol.c: Remove consistency tests that cause compiler warnings. * target.c (ffetarget_aggregate_info): Replace big switch with little call to new type module. (ffetarget_layout): Remove consistency tests that cause compiler warnings. (ffetarget_convert_character1_typeless): Pick up length of typeless type from new type module. * target.h: Crash build if target float bit pattern cannot be precisely determined. Remove all the type cruft now determined by ffecom_init_0 at invocation time and maintained in new type module. Put casts on second arg of all REAL_VALUE_TO_TARGET_DOUBLE uses so compiler warnings avoided (requires target float bit pattern to be precisely determined, hence code to crash build). * top.c: Add inits/terminates for new type module. * type.h, type.c: New module. * gbe/2.6.2.diff: Remove all patches to files in gcc/config/ directory and its subdirectories. Mon Jan 9 19:23:25 1995 Dave Love * com.h (FFECOM_F2C_INTEGER_TYPE_NODE): Define and use instead of long_integer_type_node where appropriate. Tue Jan 3 14:56:18 1995 Dave Love * com.h: Make ffecom_f2c_logical_type_node long, consistent with integer. Fri Dec 2 20:07:37 1994 Dave Love * config-lang.in (stagestuff): Add f2c conditionally. * Make-lang.in: Add f2c and related targets. * f2c: Add the directory. Fri Nov 25 22:17:26 1994 Dave Love * Makefile.in (FLAGS_TO_PASS): pass $(CROSS) * Make-lang.in: more changes to runtime targets Thu Nov 24 18:03:21 1994 Dave Love * Makefile.in (FLAGS_TO_PASS): define for sub-makes * g77.c (main): change f77-cpp-output to f77-cpp-input (.F files) Wed Nov 23 15:22:53 1994 Dave Love * bad.c (ffebad_finish): kluge to fool emacs19 into finding errors: add trailing space to :: Tue Nov 22 11:30:50 1994 Dave Love * runtime/libF77/signal_.c (RETSIGTYPE): added Mon Nov 21 13:04:13 1994 Dave Love * Makefile.in (compiler): add runtime * config-lang.in (stagestuff): add libf2c.a to stagestuff * Make-lang.in: G77STAGESTUFF <- MORESTAGESTUFF f77-runtime: new target, plus supporting ones * runtime: add the directory, containing libI77, libF77 and autoconf stuff * g++.1: remove * g77.1: minor fixes Thu Nov 17 15:18:05 1994 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.2 released. * bad.def: Modify wording of FFEBAD_UNIMPL_STMT to indicate that it covers a wide array of possible problems (that, someday, should be handled via separate diagnostics). * lex.c: Allow $ in identifiers if -fdollar-ok. * top.c: Support -fdollar-ok. * top.h: Support -fdollar-ok. * target.h: Support -fdollar-ok. * DOC: Describe -fdollar-ok. * std.c (ffestd_R1229_finish): Fix bug so stand-alone build works. * ste.c (ffeste_R819A): Fix bug so stand-alone build works. * Make: Improvements for stand-alone build. * Makefile.in: Fix copyright text at top of file. * LINK, SRCS, UNLINK: Removed. Not particularly useful now that g77 sources live in their own subdirectory. * g77.c (main): Cast arg to bzero to avoid warning. (This is identical to Kenner's fix to cp/g++.c.) * gbe/: New subdirectory, to contain .diff files for various versions of the GNU CC back end. * gbe/README: New file. * gbe/2.6.2.diff: New file. Tue Nov 8 10:23:10 1994 Dave Love * Make-lang.in: don't install as f77 as well as g77 to avoid confusion with system's compiler (especially while testing) * g77.c (main): use -lf2c and -lm; fix sense of test for .f/.F files Fri Oct 28 09:45:00 1994 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.1 released. * gcc.c: Invoke f771 instead of f-771. Fri Oct 28 02:00:44 1994 Craig Burley (burley@gnu.ai.mit.edu) * Version 0.5.0 released. Fri Oct 14 15:03:35 1994 Craig Burley (burley@gnu.ai.mit.edu) * Makefile.in: Handle the Fortran-77 front-end in a subdirectory. * f-*: Move Fortran-77 front-end to f/*.
