Fix saber includes for BFD + include files. Roll version to 3.94.2. + + * coffread.c (init_stringtab): Read length into unsigned char + array before swapping; don't assume 32-bit longs. + + * target.c (target_info): Don't bother with get_sym_file, just use + the symfile global variable. + * symtab.h, symfile.c (get_sym_file): Delete it. + + * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes. + (define_symbol): Set symbol line number to 0 if not gcc-compiled. + (read_type): Replace one more error() with complain(). + + * mipsread.c (parse_partial_symbols): Replace printf with complain. + + * i960-tdep.c: Fix copyright attribution. + + * config.gdb: Quote all backquotes in doublequotes. You can + quote me on that. BSD 4.4 shell found this one. + + * infptrace.c (throughout): The third argument to ptrace is an + int *, not an int. + + * infrun.c (wait_for_inferior): When program has terminated, we + have to call target_terminal_ours before we pop that target off + the stack (e.g. before a call to target_kill or + target_mourn_inferior). This fixes problem where a program + terminates, then GDB stops for (tty output) and you have to type + "fg" to the shell to resume it. FIXME: This code for what to + do after termination really should be in normal_stop instead. + + * gdbcore.h (read_memory_check): Change declaration; it changed + names months ago. + + * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD + 4.4 prereleases, this avoids a bug in their sgtty compatability + support. + * remote.c: Use terminal.h rather than hand-rolling the same. + + * signame.c, signame.h (psignal): Arg is unsigned, not int. + * utils.c (strsave, strstr): Fix arg types. + * valprint.c (val_print): lint + + MIPS symbol table support from Per Bothner: + + * symfile.c (symtab_fns): Remove initializer table that needs to + be hacked for each new symbol file format supported. + (add_symtab_fns): New function, chains symbol table + handlers into the global list. + (symfile_init): Search this list. + * symfile.h: Add next pointer, declare add_symtab_fns. + * coffread.c (_initialize_coffread): Call add_symtab_fns. + * dbxread.c (_initialize_dbxread): Call add_symtab_fns. + + * mipsread.c (psymtab_to_symtab_1): return void instead of (struct + symbol *). Thus, we no longer need the hack to trash + pst->filename. Good, since that hack confused code in symfile.c! + + (reorder_symtabs, destroy_all_symtabs): Removed static + all_symtabs, which was used to qsort symtabs in reorder_symtabs. + Instead, the latter now uses a temporary array (stack-allocated + from an obstack, and then freed). + + (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they + haven't been set in the outermost stBlock of a procedure. This was + a problem with f77 binaries on Ultrix 4.?. + + (new_symtab, new_symbol, new_type): Continue changing code to use + obstacks more and otherwise conform to dbxread internal style. + Made the free_code of symtabs be free_linetable (as in dbxread) + instead of free_contents. This implies memory leaks when reading + a new symbol table, until the conversion is finished. Did change + (struct symbol) and (struct type) to be allocated on the + symbol_obstack. Blocks and blockvectors are among the things + still "leaking." + + * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been + tested much, but it solved one problem (reported by Meissner), and + cleans up some other things. The problem happened when an + included file contains actual code (functions) and not just + definitions. The mips coff is a little inconvenient there, since + it may cause a procedure to be mapped to the wrong psymtab. + + * mips-tdep.c (heuristic_proc_desc): Minor cleanup. + * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME, + this will need work for the new core paradigm. + + Opcode patches from the net: + + * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and + ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were + missing altogether - they are added here. From Bruce Bauman. + * mips-opcode.h: The low mask for C0 instructions was too small. + From Garrett Lau. I modified the fix to check the entire 32-bit + opcode. + + * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce + Bauman. + +Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com) + + Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04): + + * dbxread.c (read_type): Pointer subtraction (value_sub in + valarith.c) sometimes failed because the types of the + pointers being subtracted were not identical. + These differed because dbxread.c was allocating pointer types + using dbx_alloc_type+smash_to_pointer_type instead of + lookup_pointer_type. I failed to find a justification for the + former, so I changed it to use the latter. Similarly, I + replaced smash_to_function_type by lookup_function_type, + and smash_to_reference_type by lookup_reference_type. + + * mipsread.c (parse_symbol, upgrade_type, parse_procedure, + _initialize_mipsread): corresponding changes. + + * symtab.c (smash_to_{pointer,reference,function}_type): eliminate. + + * source.c (mod_path): Do tilde_expand on each component of the path, + rather than on the (list of) paths as a whole. + (print_source_lines): Set first_line_listed in addition to + current_source_symtab and current_source_line. If the source was + not findable, after a "dir" command to fix the problem, + a "list" would get the wrong lines. + + While I was there... (gnu): + + * dbxread.c (read_type): Change error to complaint. + +Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com) + + First attempt at detailed understanding of symbol table memory alloc. + + * dbxread.c (dbx_symfile_read): Free our string table if we + aren't the mainline. Free the "info" struct since we're done with + it. + (init_psymbol_list): Free any previously allocated psymbol lists. + (): FIXME: Should realloc-down the psymbol lists when done reading + the main symbol file? + + * symmisc.c (free_symtab): Free fullname field too. + + * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D. + (REGISTER_ADDR): Make result type unsigned int. + + * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that + define REGEX must also define REGEX1 (its dependency). + +Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com) + + * tconfig/i960: No longer works, points you at vxworks960 or + nindy960. + + * xgdb.c, XGDB-README: Remove file. Users can get the much + better xxgdb. + * Makefile.dist: Remove all trace of xgdb. + + * breakpoint.c (breakpoint_1): Pass demangle arg to + print_address_symbolic. + (clear_breakpoints): Remove unused function. + (breakpoint_re_set_one): Guts of breakpoint_re_set. + (breakpoint_re_set): Use catch_errors to do them all anyway. + + * gdb-int.texinfo (Host versus Target): Add section on what is + a "host" feature versus what is a "target" feature. + + * infcmd.c (path_command, path_info): Handle the PATH variable + (object search path) as conveniently as the source search path. + * environ.c (set_in_environ): Set some vars in GDB's environment, + in addition to the child's.

Used by path_command. + (directory_command): Call it. + * defs.h (strsave): Declare. + + * utils.c (sevenbit_strings): Add new printing option. + (printchar): Use it. + (strsave): Provide this handy helper routine. + (set_width_command): Rename set_screen_width_command. + (_initialize_utils): "set screen-width" => "set width"; + "set screen-height" => "set height"; add sevenbit-strings. + + * infcmd.c (do_registers_info): Print floating point registers + in raw hex as well as float format, regardless of whether it is + a "virtual" convertible register. + * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float + regs as a double, just in case it's being used that way. + * values.c (unpack_long): Comment on array/function coercion. + (unpack_double): Argument is in target byte order now. For + integer arguments, just call unpack_long and float the result. + * m68k-tdep.c: include defs.h for "const" handling. + * remote-nindy.c: Use ieee-float stuff. + (nindy_fetch_registers): Unpack double regs to host double, then + to extended. + (nindy_store_registers): Pack extendeds to host double, flip + around by misusing unpack_double, send as target double. + + * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of + zero, as when stopped at the first instruction of a process. + + * blockframe.c: Fix filename in comment (param.h => tm.h). + * sparc-tdep.c (skip_prologue): More explicit nudging comments. + * tm-68k.h: Fix typos. + +Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com) + + Changes from a bringup on the DEC Vax under Ultrix 4.0. + + * coredep.c (fetch_core_registers): Pass end-address of register + section to register_addr as expected. Don't call supply_register + if we'd just pass it garbage. + + * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix. + + * exec.c (xfer_memory): Use boolean xfer_fn result, not int. + + * target.c (push_target, target_info): Cast enums to int for < or + > comparison. + + * stack.c (print_frame_info): Identify source file & line + even if we can't print it. + + * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0. + +Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com) + + Clean up IEEE floating point support. + + * ieee-float.h: New file. + * ieee-float.c: Write real routines to convert between host + doubles and various target IEEE extendeds. + * m68k-xdep.c: Eliminate assembler code for extended floats. + * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3, + sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o. + * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL, + REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and + double_to_ieee_extended. + * i960-tdep.c: Define ext_format_i960. + * m68k-tdep.c: Define ext_format_68881. + * sparc-tdep.c: Define ext_format_sparc, though unused. + * Makefile.dist (HFILES): Add ieee-float.h. + * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT + macros. + + Obsolete the "coffstrip" program in favor of using BFD's strip. + + * nindy-share/coffstrip.c: Remove file. + * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip. + * Makefile.dist: Remove references to nindy-share/coffstrip.c. + * tconfig/nindy960: Remove reference to coffstrip.o. + + * Makefile.dist: Roll version number to 3.94.1 (not yet final). + +Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com) + + * symfile.h: Add symfile_bfd, common between dbxread and coffread. + * dbxread.c: Remove static symfile_bfd. + * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though + it is not used yet. + * inftarg.c (child_detach): Pop the child_ops vector if the + detach is successful. + * remote-nindy.c (nindy_create_inferior): Don't push a new + nindy_ops since nindy uses the same one for execution and memory + examination anyway. + * core.c (core_ops): Use child_attach and child_create_inferior + rather than default attach and create_inferior functions. + + Handle floating point registers in core files. + + * sparc-xdep.c (fetch_core_registers): Rewrite for float support. + * sun3-xdep.c (fetch_core_registers): Rewrite for float support. + This version untested since BFD doesn't yet support sun3 core + files. + * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling + conventions. Fix comments and style. This version has not + been compiled yet, since we have no HP inhouse. + * core.c (get_core_registers): Look for two sections, ".reg" + and ".reg2", and pass both to fetch_core_registers sequentially. + + Revise directory path yet again. + + * source.c (forget_cached_source_info): Not static any more. + (init_source_path): New default source path is "$cdir:$cwd". + (dir_command): Handle variable arguments ($cdir, $cwd). + (source_info): Print "Compilation directory" rather than + "Originally compiled in" to remind people of $cdir. + (openp): If the path contains $cwd, use current directory. + (open_source_file): If compilation directory is known, replace + first $cdir in path with the compilation directory. + (print_source_lines): Even if we can't print the lines, set the + current symtab and line for future commands like "info source" or + "breakpoint".

Byte-swap LOC_CONST and + LOC_LABEL values to target order. Add LOC_LOCAL_ARG. + (locate_var_value): Use read_var_value and use its lazy address + as the location of the var's value. Lint. + + * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning + instructions. + + * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove + obsolete Intel versions in favor of vxgdb versions. + (check_host, byteswap, byteswap_val, reorder_val): Eliminate + code dealing with byte order of values, which Intel did in host byte + order rather than gdb-4's target byte order. + (i960_frame_chain_valid): Move to nindy-tdep.c. + (examine_prologue, skip_prologue, frame_find_saved_regs, + frame_args_address, leafproc_return, saved_pc_after_call, + pop_frame): Add vxgdb versions from Mark Fox. + (examine_prologue, frame_struct_result_address): Add code + to deal with the saved value of G13 (struct return address + pointer). + (frame_args_address): Modify Mark's version to prefer the + saved value over the current value in the topmost frame. + Cache result in the frame info to avoid performance hair in + callers. + (print_fault): Add gdb960 code for printing faults. + (_initialize_i960): Actually call check_host. + + * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended): + add stub routines.

Lint. + (ptype_command, display_command): Eliminate have_inferior_p and + have_core_file_p in favor of target_has_stack or + target_has_execution. + (print_frame_args): Handle LOC_LOCAL_ARG.

Allow load + to be interrupted. + (net_ptrace): Remove unused routine. + (vx_wait): Adopt code from vxgdb960 to cope with broken + connections to target machine and prompt to disconnect. Remove + debug printouts. Map some EVENT_'s to SIGnals. + (add_symbol_stub, vx_open): Print names of object files we found, + and "ok" if we read their symbols OK. Clarify output in general. + (vx_attach, vx_detach, vx_kill): Add these commands. + (vx_convert_from_virtual, vx_convert_to_virtual): Simplify. + (vx_run_ops): Turn off all_mem, to avoid spurious msg in the + "info files" output, and create_inferior, since we already have + an inferior. + + * stack.c (frame_info): Replace Frame_unknown with 0. + (print_frame_arg_vars): Handle LOC_LOCAL_ARG. + (return_command): Pop until the PC matches as well as the FP, + so it works even if the FP is shared with another function, + as in "frameless" or "leaf" procedures. + + * symfile.c (load_command): renamed from add_file_target_command. + (add_syms_addr_command): renamed from add_file_addr_command. + (add_syms_command): Stub to call target_add_syms. + (_initialize_symfile): Change command names and descriptions, + add-file => add-syms, and load from alias to its own command. + + * target.c (kill_or_be_killed, maybe_kill_then_attach, + maybe_kill_then_create_inferior): Default for attempts to start + a process, if one is already running, is to ask about killing + it and retry if yes. + (upstack_create_inferior): #if-0 it, strata obsolete it. + (push_target, unpush_target, pop_target): to_close() a target + before unstacking it. + (target_info): Renamed from target_files_info. + (_initialize_targets): Rename "i files" as "i target", accessible + under both names. + + * target.h: Improve comments about the target_ vectored routines. + + * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h. + Convert commenting style to standard GNU style. + (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized. + (SKIP_PROLOGUE): No longer a no-op. + (SAVED_PC_AFTER_CALL): Now handles leaf procedures. + (*_REGNUM): Sort register numbers. + (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE, + MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE, + REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs + are now 10 byte extendeds, not 8 byte doubles. + (FRAME_CHAIN_VALID): Make this config-dependent, since it differs + for nindy versus vxworks targets. FIXME, this should possibly go + in the target vector. + (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both + frame_saved_regs and arg pointer with each frame. + (FRAMELESS_FUNCTION_INVOCATION): New leafproc support. + (FRAME_ARGS_ADDRESS): Use cached result. + (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing. + (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn. + (PRINT_RAMDON_SIGNAL): Call print_fault. + (POP_FRAME): Now works. + + * tm-nindy960.h: Break this off tm-i960.h.

The rest is Bothner speaking: + + The next message is a merger of Alessando Forin's mips port with + mine. I've tried to use my good if biased judgment to get + the best of both. It *does* need testing. + + Some of the changes are general, *not* mips-specific. + + param.h: + Didn't believe in little-endian bit order. + There are still inconsistencies about whether flags + like BITS_BIG_ENDIAN are integer (#if ...) or + boolean (#ifdef ...). I tried to paper over them. + + dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h: + Moved some misc_function code that was common to + {dbx,coff,mips}read.c to symtab.c. + In the process, I think I cleaned things up a bit. + At the same time, moved obsavestring and obconcat to symtab.c. + + dbxread.c: + Removed obsolete condense_addl_misc_bunches (use + condense_misc_bunches(1) instead). + + exec.c: + Needed to include <sys/dir>, at least on DECstations. + + valops.c, mips-tdep.c, tm-mips.h: + Added PUSH_ARGUMENTS macro to support funny argument-pushing + conventions (when STACK_ALIGN is insufficient). + Needed on mips, where doubles need 8-byte alignment, + but ints only need 4. + + mips-opcode.h: + Removed cruft that was not being used. + Merged in many fixes (most from Frank Yellin, fy@lucid.com). + + mips-pinsn.c: + Print $ before register-names (I think that makes things a little + more consistent). + Never print two instructions, even if one delays. + Removed hex-disassemble set_cmd. (This is not mips-specific, + so I think the argument is whether it is generally worthwhile or not. + I'm inclined to think not, given how easy it is to + convert between radixes in gdb.) + + mipsread.c: + This is basically Alessando's code. + It doesn't use obstacks; I changed it to use obstacks + in a few minor places where using malloc causes a + memory leak. (Probably, more places could/should be changed.) + I added record_misc_function where it was missing. + In symbol_file_command and add_file_command, I tried + to make the code consistent with more recent versions. + Minor sylistic changes in parse_procedure. + Make a .gdbinfo. psuedo-symbol point back to the real + procedure symbol (using the isym field). + + mips-tdep.c: + This is basically from my port, but with a lot of details + and a number of routines merged in from Alessando's version. + I basically used my code "raw" backtrace (use heuristics + from the actual code, rather than symbol table info) - though + the idea is Alessandro's. I feel my code is a little cleaner + here, particularly in being a little more flexible, such as being + able to handle gcc-produced code (which it now can). + It also doesn't do frame caching (which is not useful + more recent gdb versions). + I also used my code for push_/pop_dummy, more or less. + I tried to incorporate AF's code for testing sigtramp + while backtracing; I probably got it wrong. + Added mips_print_register, which tries to scrunch as much + information as possible on a screen... + Removed the skip-prologue set_cmd. As with hex-disassemble (see + under mips-pinsn.c), I don't see anything mips-specific here, + and I don't see it being all that useful anyway. + + tm-mips.h: + Added a $fp psuedo-reg distinct from $fp (nice for gcc). + Use more register names (rather than hard-cases numbers). + +Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint) + + * Hack up 3.90.11 changes: + + * Makefile.dist (depend): parameterize $(GCC). + Add solib.c and solib.o. + (readline): Fix vpath for both absolute or relative SRCDIR. + + * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs. + Also, let the part I didn't understand at least compile so + I can test the rest.

Here are my suggestions. + + These patches all attempt to handle TYPE_CODE_REF (as in C++) better. + + findvar.c: + Do automatic de-reference when taking the address of a reference. + printcmd.c: + Don't deref_ref when printing parameter lists. + valops.c: + More attempts at treating refernences properly. + valprint.c: + In val_print, if deref_ref==0, don't print dangling " = ". + value.h: + Add COERCE_REF macro, which de-references an REF. + + * Merge changes from Per Bothner: + +* Fixed (Sony news)-specific configuration problems. +* Fixed other problems with using vanilla pcc and libc (enum problems; +assumption that vsprintf exists). +* Some major speed-ups (finc_pc_partial_function now caches a match; +parsing avoids duplicate symbol_lookup calls). +* Changed handling of baseclasses (no longer use baseclasses field +of struct type, use the first n_baseclasses fields instead). +* Various minor changes/fixes, most C++-related. + +blockframe.c: +Cache the most previous match from find_pc_partial_function. +(Save both low and high ends of matching function's pc range.) +This speeds up the loop of infrun.c:wait_for_inferior quite +a bit, and makes step/next commands much zippier. +command.c: +Added an enum->int cast (otherwise, some compilers barf). +dbxread.c: +No longer set baseclass offset to 0, since multiple +inheritance now mostly works. +Added a number of casts, to shut up compiler warnings +(after stabs where made enums, not ints). +When discarding a symbol table (in symbol_file_command), +must clear the cache introduced in blockframe.c. +Don't convert $vtbl_ptr_type to vtbl any more. +Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h). +Mask off sign bit emitted by g++ for virtual table offset. +Set voffset to -1 (not 1) for static member functions. +expread.y: +Changed parsing/lexing of names to avoid doing symbol lookup twice +(once when lexing to determine symbol class, once for real). +Now only call symbol_lookup once. Fields of 'this' win especially big. +printcmd.c: +Subpress printing addr twice in the case of 'x/s addr'. +symtab.c: +lookup_basetype_type is no longer used. +Add find_methods as recursive helper function to decode_line_1. +This allows multiple inheritance to work. +Also, once one or more matches has been found, do not look in +base-classes. (Baseclass methods would be overridden, anyway.) +symtab.h: +Removed baseclasses array in struct type. +Instead of using baseclasses[i], use fields[i-1]. +Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual. +Changed sign convention of voffset (previous was inconsistent). +tm-news.h: +Some macros (CALL_DUMMY and relatives) were missing. Put them back. +utils.c: +Used to assume existence of vsprintf. Re-written to not need it +if HAVE_VPRINTF is undefined. +valops.c: +typecmp was too pessimistic. Made it less so. +valprint.c: +Don't print space after address. +If vtable points to a misc symbol (with 0 offset), print it, +since that indicates the actual class of the object. +Changed ype_print_derivation_info to use new inheritance +scheme (without baseclasses vector). +values.c: +In value_primitive_field, fixed some bugs left over from previous set of fixes. +Also, changes needed because TYPE_BASECLASSES were removed. +xm-news.h: +REGISTER_U_ADDR didn't work for PC. Rewrote to use an array. + +Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint) + + * source.c: + If there is no path set, and the symbols don't indicate what directory + a file was compiled in, look in the current directory. But either + a path or a known compilation directory will prevent this. + + * dbxread.c: + Three independent bug fixes: + * Remove the #if 0 block that breaks some stuff. + * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C; + adapt gdb to either SunOS 4.0.* or 4.1. + * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think. + + * symtab.c: + Instantiate the class T when looking for methods in it. (Tiemann@sun) + + * valprint.c: + (type_print) Demangle the name being printed. + (type_print_base) Handle botched demangling without coredump (tiemann). + + * values.c: + (check_stub_method): Document routine. + (tiemann) fix bug for no-arg functions + Avoid clobbering beyond end of malloc'd storage. + Terminate the argument list properly. + +Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu) + + * Changes merged by John Gilmore: + +breakpoint.c: + In breakpoint_1, use new print_address_symbolic instead + of find_pc_partial_function. (This forces use of assembler-level + addresses, and avoids misleading non-mangled source-level names.) +cplus-dem.c: + Generalize ansi argument such that -1 means skip arglist totally. + Removed global variable print_ansi_qualifiers (which made + code non-reentrant), in favor of extra explicit arguments + to internal routines. +printcmd.c: + Add new helper function print_address_symbolic. + Use find_pc_misc_function instead of find_pc_partial_function + (since we want assembler-level symbols here). +stack.c: + Print unknown function as just "f (...)", not "f (...) (...)". + Use new fputs_demangled explicitly. +symtab.c: + Fixed a typing violation (problem: value.h cannot be imported + without renaming many variable in this file). + lookup_symbol: If no matching misc_func, look for a C++-mangled name. + decode_line_1: Moved forward some never-reached code. + Made decode_line_2 skip function prologues correctly. +utils.c: + fputs_filtered should not demangle by default. + Add new fputs_demangled to demangle on demand.. +valops.c: + Change value_struct_elt to use value_primitive_field (using recursive + utility function search_struct_field). This allows foo.bar to work + for multiple inheritance (so far only for data fields). + Change check_field in the same way (recursive helper function + to support multiple inheritance). + (Note: there are more of these problems that I haven't fixed. + Any code that says TYPE_BASECLASS (t, 1) is probably wrong.) + value_of_this: 'this' symbol name is now just "this", note "$this". +valprint.c: + Don't print static members. + Avoid printing "members of <type>" if there are none. + Simplified type_print_derivation_info by merging duplicate code. + Remove useless blank lines in type_print_base (ptype command). +value.h: + Added declaration of new routine value_primitive_field. +values.c: + Added value_primitive_field which is generalized version of + value_field that can handle multiple inheritance (non-zero offsets etc). + Re-implemented value_field to call value_primitive_field. + +Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint) + + * infcmd.c -- insert else to avoid 'delete env' coredump when you + delete the whole environment.
