This yields correct C++ semantics, and - preserves the location information, which has the nice effect - that &(&R) given the location containing R. - * values.c (value_copy): Make non-static (used by value_addr). - * eval.c (evaluate_subexp_for_address): Use the default - scheme (with value_addr) for a variable if it has TYPE_CODE_REF. - * valops.c (value_addr), eval.c (evaluate_subexp_for_address, - evaluate_subexp_with_coercion): Factor out some common - expressions into variables, for easier reading. - * findvar.c (locate_var_value): Remove code to handle - TYPE_CODE_REF - it should no longer be needed. - * valops.c (value_assign): Do a COERCE_REF on the - destination operand, for correct C++ semantics. - * valarith.c (value_x_binop): Ditto: De-reference C++ - references in the arguments. - * valops.c: ANSI-fy: bcopy->memcpy, bzero->memset. - -Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com) - - * dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC. - * symtab.c (gdb_mangle_name): Recognize and handle - constructors specially. - * symtab.c (check_stub_method): Test for failure from - cplus-demangle by calling error() instead of seg-faulting ... - -Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com) - - * defs.h: Add definition of null_cleanup() - - * procfs.c: Many small changes to add base support for a new - "info proc" command (currently only printing of the address - space mapping is implemented) and allow iteration over the - address space mapping, calling an arbitrary function for each - mapping (used for shared library support). - - * solib.c: Change all ifdefs that checked for "sun" to check - for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to - handle locating the debug base address even when not currently - stopped at the dynamic linker entry point. - - * utils.c: Add null_cleanup() as a known function that does - nothing to serve as a base for possibly long cleanup chains - with no specific "first cleanup" to serve as an anchor. - - * xm-sysv4.h: Add define of SVR4_SHARED_LIBS - -Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com) - - * arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h, - pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed - - these are all essentially the same as the versions - in ../include/opcode. The remaining *-opcode.h here - are not quite so obviously the same, and need study. - * arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c, - tahoe-pinsn.c, vax-pinsn.c: Change so these include - opcode/FOO.h (actually ../include/opcode/FOO.h) - instead of the recenntly departed opcode-FOO.h files. - * sparc-pinsn.c: Now that we're using the much tighter - opcode table in ../include/opcode/sparc.h, we shouldn't - need to sort the opcodes before dis-assembly. - - * symtab.h, symmisc.c: Make cplus_struct_default be const. - * symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro. - * symmisc.c: Remove unused 'nfields' variable. - * buildsym.h: Add extern decl of unknown_symtype_complaint, - since it used used by partial-stab.h (included two places). - * partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that - we should never hit the default case (until new stab codes - are added). Hence, we can leave the complaint in the - default case in even when DBXREAD_ONLY is off. - * partial_stab.h: Recognize a pair of N_SO stabs (one for the - directory, one for the filename proper) without peeking ahead. - * dbxread.c, mipsread.c: Because of previous change, don't need - ugly CHECK_SECOND_N_SO macro. - * buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a - macro that invokes a function pointer in next_symbol_text_func. - * mipsread.c: Added comments various places to - explain what is going on. - * mipsread.c (parse_symbol): Support the new (SGI-specific?) - symbol types stStruct, stUnion, and stEnum. - Also, some fixes in the code for dealing with tags. - * mipsread.c: Change handling of startup_file_start and _end - - now just use the textlow and texhigh of a psymtab - to check if we've found the startup-file. - * mipsread.c: Replace s_idx by global cur_sdx in many places. - This is so mips_next_symbol_text can get at it. - -Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com) - - * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from - dbxread.c to symmisc and change name to add_psymbol_to_list. - Ditto for add_psymbol_addr_to_plist(). Also expand their - body to not use ADD_PSYMBOL_VT_TO_LIST. - - * dwarfread.c: Remove add_psymbol_to_list() and convert usages - to the ADD_PSYMBOL_TO_LIST macro. - - * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG" - to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST. - - * partial-stab.h, symfile.h: Move definitions of the macros - ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from - partial-stab.h to symfile.h. They aren't stab specific. - Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy. - -Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com) - - * Makefile.in: Roll VERSION to 4.3.2. - -Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com) - - * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted. - * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c: - Include <opcode/FOO.h> instead of <FOO-opcode.h>. - - * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c, - dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only - allocated when it is needed. Until it is needed, it points - to a shared statically allocated structure. - - * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code - in read_ofile_symtab to recognize two initial N_SO stabs, - and let process_on_symbol handle it. This is cleaner, more - efficient, and lets mipsread.c share the same code. - - * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST - and related macros to here ... - * dbxread.c: ... from here. - * symmisc.c: Move the "overflow" handling from - ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list. - * dwarfread.c: Re-write add_psymbol_to_list to use - ADD_PSYMBOL_VT_TO_LIST macro. - - * mipsread.c: Extend mipsread.c to handle stabs-style symbols - encapsulated in ecoff symbols. This enable full g++ debugging. - * partial-stab.h: Move the code for pre-scanning symbols - and building psymtabs to an include file, out from dbxread.c. - This way, the same code can also be used by mipsread.c. - * dbxread.c, buildsym.h: Various changes to allow some functions - to be used by mipsread.c (also some arguable stylistic changes). - - * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now, - since mips-tfile puts relocatable addresses into LBRAC/RBRAC - stabs. - - * mipsread.c: Replace code to handle ambiguous tag blocks. - Instead of allocating a TYPE_CODE_UNDEF, guess (by looking - at types and offsets) if a tag is a struct, union, or enum. - Still patch it later if we find out for sure. - * mipsread.c: In various ways, replace Forin's - ideo-syncratic code by code that fits better with the - rest of gdb, for both stabs-based and ecoff-based symtabs. - E.g. use end_psymtab; don't do extra passes over FDR table to - pre-partition global data; don't use external symbols to - create static/global symbols (just put them in the - misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't - sort psymtabs or symtabs; use obstacks more. - - * symtab.c, mipsread.c, dbxread.c, buildsym.c: - ANSIfy: Replace bcopy by memcpy, bzero by memset. - -Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com) - - * solib.c (locate_base): Fix uninitialized variable that was - causing return of random value to callee. - - * config/mh-amix, config/mh-i386v4: Change to find alloca by - compiling and linking alloca.c, even when it is not strictly - required. Also arrange to link with -ltermlib rather than - -ltermcap. - - * Makefile.in: Move TERMCAP definition to prior to inclusion - of host makefile fragments so it can be overridden. - -Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com) - - * xcoffread.c (read_symbol_lineno): Logic error in incrementing - symbol table entry number. (From Metin Ozisik.) - -Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com) - - * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a" - so compiles with native compilers (without builtin alloca) can - pick up the version from the bsd emulation library. However, we - search the standard C library first so we don't pick up lots of - other broken stuff from libucb.a, that we *don't* want. - - * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h: - Change svr4 references to sysv4. - - * source.c: Move declaration of external function index to - front of file so it is in scope for all references. - - * utils.c (error, fatal): Make definitions consistent with - defs.h declarations (declared as "volatile void"). - -Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com) - - * rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow. - -Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com) - - * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c, - sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h, - vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums. - -Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com) - - * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES - for these SVR4 systems. - - * symfile.c (symbol_file_add): When verbose is set, print - the names of files from which symbols are being loaded, as - when from_tty is true. - - * solib.c: Completely reorganized (rewritten) to support - SVR4 shared libraries in a manner very close to the original - SunOS implementation. This support is expected to change and - become more general at some future time. The SVR4 version - does not yet work for attached processes, for example. - - * dwarfread.c: Arrange in dwarf_build_psymtabs() for the - relocation address to be valid whether or not symbols are - being read from a shared library or an executable. Use the - relocation address recorded in the psymtab when reading - full symbol tables (in read_ofile_symtab). Ensure that the - relocated address ranges are recorded in partial symtabs. - - * elfread.c: Add new function elf_interpreter() to return the - string from the ELF ".interp" section. This is the interpreter - that the kernel tries to run and feed the executable to. - Expand arguments to record_misc_function to include a type arg. - Modify elf_symtab_read() to supply the type arg, and to do symbol - relocations for symbols read in from shared libraries. - - * procfs.c: Add new functions proc_base_address() and - proc_address_to_fd(), used by shared library support. - - * tm-svr4.h: Add macros to support SVR4 shared libraries. - Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK, - CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK. - -Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com) - - * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove - unused START_INFERIOR_HOOK. - - * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte) - to account for slow loading from floppies. - (eb_create_inferior): New fn, from eb_start and - nindy_create_inferior. - (eb_close): Only use log_file if nonzero. - (eb_xfer_inferior_memory): If not writing, then read! - (eb_read_inferior_memory, eb_write_inferior_memory): Return length. - (eb_kill): A new no-op. - (eb_mourn_inferior): Remove breakpoints, then generically weep. - -Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com) - - * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix - miscellaneous comparisons of integer with NULL that elicit - compiler warnings about comparison of integer with pointer, when - NULL is ((void *) 0) rather than just a bare 0. - -Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com) - - * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint - while we reset it, in case of problems. Print breakpoint number - in error messages. - - * buildsym.c (read_struct_type): Avoid sun3 compiler bug with - foo[--n]. - - * source.c (find_source_lines): If getting file mod time fails, - don't warn. - - * target.c (target_xfer_memory): If errno is set, return it, - rather than EIO. - -Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com) - - * Makefile.in: infodir belongs in datadir. - -Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com) - - * symtab.h (struct fn_field): Add new fields `is_private', - `is_protected', `is_stub', making room by reducing the size of - `voffset'. - (struct fn_fieldlist): Delete the fields `private_fn_field_bits' - and `protected_fn_field_bits'. - (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted. - (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted. - (TYPE_FN_{PRIVATE,PROTECTED}): Deleted. - (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros. - * valops.c, valprint.c, symtab.c: All callers updated. - - * buildsym.c (read_struct_type): Delete the `visibility' field - from `struct next_fnfield', and rework code so that visibility - info is stored into the fn_field directly. Also, hacked to set - TYPE_FN_FIELD_STUB for both static and normal member functions. - -Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com) - - * i386-tdep.c: Fix a problem on i386 systems where buffered code - stream access was failing to take into account the minimum size - granularity of the code section. For now, the buffering is simply - disabled. There is a similar problem in the i386 disassember code - that has not yet been fixed (FIXME). - - * gmalloc.c: Use macros to hide some of the ugly casting required - in the previously applied fix for pointers with high bits set. - -Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com) - - * Makefile.in: Roll VERSION to 4.3.1. - -Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com) - - GDB-4.3 release! - - * Makefile.in: Roll VERSION to 4.3 - * README, TODO, WHATS.NEW, depend: Update. - - * inflow.c (terminal_inferior): Avoid error msg if attached. - - * gmalloc.c: Fix bug that causes malloc & free to - fail on systems where pointers have the high bit set (0x800efcf0 - for example). The problem is that the difference between two - pointers is a signed integer, so the computation - - (char *) 0x800efcf0 - (char *) 0 - - yields a negative value. The sign of the result of the modulus - operator is machine dependent for negative operands, thus it is - possible for it to end up negative. From Fred Fish. - -Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com) - - * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA. - added clean-info. added some standards.text support and made it - look like our other Makefiles. - - * configure.in: mark this directory target dependent. configure - now runs entirely in objdir so make existence tests and - references against ${srcdir}. - -Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com) - - * dwarfread.c (enum_type, struct_type): Fixes for opaque and - anonymous enumerations, structures, and unions. Now passes all - the current gdb test suite tests. - -Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com) - - * Makefile.in: idestdir and ddestdir go away. Added copyrights - and shift gpl to v2. Added ChangeLog if it didn't exist. docdir - and mandir now keyed off datadir by default. - -Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com) - - * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in - mid-line, be more careful about possibly advancing to the next line. - -Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com) - - * cplus-dem.c (cplus_demangle): Call `string_need' when - null-terminating a partially-computed string. - -Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com) - - * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a - symbol to the symbol table for each member of the enum. - - * dwarfread.c (struct_type): Build a correct TYPE_NAME. - - * dwarfread.c (add_enum_psymbol): New function to extract enum - member names and add them to the partial symbol table while - building partial symbol tables. - -Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com) - - * symtab.c (check_stub_method): Must allocate two extra argument - slots (one for `this', one for arglist terminator). - -Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com) - - * inflow.c (child_terminal_info): Supply missing '"' character. - - * buildsym.c (define_symbol): Supply missing parenthesis. - -Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com) - - * coredep.c (fetch_core_registers): Fencepost error. Fixed by - Jay Lepreau <lepreau@cs.utah.edu>. - - * inflow.c: Remember whether GDB has a terminal. Avoid switching - terminals back and forth if we don't have one. - - * c-exp.y (parse_number): Zero is not an unsigned int constant! - * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form. - - Improve type parsing. - * buildsym.c (define_symbol, read_range_type): Add - long_kludge_name that passes the names of range types being - defined, down to where we must choose between 'int' and 'long' - variants. This fails on Sun C anyway since the compiler itself is - confused between int and long. - (read_array_type, cleanup_undefined_types): Correct the size of - array type whose element-type size isn't immediately known. - - Early preparation to blow away many builtin types, building them - on the fly as needed. Don't compare types to builtin types with - ==; examine the relevant fields instead. - * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==. - * buildsym.c (define_symbol, case 'p'): Avoid ==. - * valops.c (value_arg_coerce): Avoid ==.

Breaks out symbol-table-building routines - from dbxread.c, so they can be shared with xcoffread.c. - * buildsym.h: New file. Declarations for buildsym.c users. - * dbxread.c: Remove large chunks into buildsym.c. - * Makefile.in: Add buildsym.c and buildsym.h. - - * symfile.c (syms_from_bfd): New routine. - (add_symbol_file): Call it to do the real work. - (syms_from_bfd): Initialize entry_point before calling symfile_init. - * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c: - Avoid declaring or setting entry_point (symfile.h & symfile.c cope). - -Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com) - - * cplus-dem.c (cplus-demangle): added support for templates, static - data, and the new (correct) mangling for destructors. - - * dwarfread.c: (dwarfwarn): created a varargs version of - dwarfwarn, for non __STDC__ compilers. - - * c-exp.y: (yylex): added match for "template" token. - (typebase): added TEMPLATE name '<' type '>' clause, for explicit - specification of template types. - - * symtab.c: (lookup_template_type): new function for finding - templates in symbol table. - (type_name_no_tag): changed to explicitly check for s/u/e at the - beginning of the symbol - if it is a template, none of these will - be there (but the name will still contain spaces.) - -Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com) - - Various fixes to improve g++ debugging. - * symtab.h: Add is_const and is_volatile flags for each method. - These are bit fields - take their space from voffset, - which shrinks to 30 bits. Since voffset is now a bitfield, - make it unsigned for portability. This changes its interpretation - slightly: Static methods now have voffset 1 instead of -1, - and virtual offsets start at 2, not 1. - * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name, - since it now returns an entire magled method name, not just - the type part. This avoids some duplication. - It also allows us to correctly mangle const and volatile - methods (using the new is_const and is_volatile bit fields - mentioned above). - * valprint.c (type_print_base), values.c (check_stub_method): - Simplify by using new gdb_mangle_name. - * values.c (value_headof): Fix to correctly handle single - inheritance (actually two fixes, either of which suffices). - * dbxread.c (read_struct_type): Handle const and volatile - method specifiers. - * dbxread.c (read_struct_type): Yet one more place where - we must handle '\\' continuations. - * valprint.c (vtbl_ptr_name): Add final '\0'. - -Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com) - - * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of - short return values for sparc and 68k. Patch from Paul Eggert. - - * coffread.c, coredep.c, i386-xdep.c: install patches for - SysV/386 3.2 from Mauro DePalma. - -Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com) - - * core.c (core_file_info), exec.c (exec_file_info): Print file - type. Use printf_filtered. - - * valops.c (value_fetch_lazy): Avoid 0-length fetches. - -Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com) - - * dwarfread.c: Add casts to remove compiler warnings. - - * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h, - tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h, - tm-sun3.h: Remove locally duplicated code for calling functions - in the inferior. The only differences were in the specific trap - vectors used and whether or not an fpu was present. These are - now handled by appropriate definitions of BPT_VECTOR and - HAVE_68881 respectively. Other minor obvious cleanups. - - * valops.c: Correct a minor misspelling. - - * utils.c: Remove local BSD/USG hacks that are now in libiberty. - - * dwarfread.c: Remove prototype for dwarfwarn. Does not work - with <varargs.h>. - -Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com) - - * stack.c (frame_command): Always print. Use new - frame_select_command to select a frame without printing. - - * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable. - -Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com) - - * dwarfread.c: New file for DWARF debugging format support. - - * elfread.c: New file for ELF object file format support. - - * procfs.c: New file for SVR4 /proc (process file system) support. - - * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for - Amiga UNIX support. - - * xm-svr4.h, tm-svr4.h: New files for SVR4 support. - - * xm-m68k.h: New file for host machines with m68k cpu. - - * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR. - Add elfread.o and dwarfread.o to OBS. - - * symfile.h: Add "elf" to list of supported formats in comment. - - * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin - types to gdb, builtin_type_long_double, builtin_type_complex, and - builtin_type_double_complex. Add and use new TARGET_SHORT_BIT, - TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT, - TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and - TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated - types on the target machine (ala the existing TARGET_LONG_LONG_BIT). - - * infrun.c: When using SVR4 /proc interface instead of ptrace(), - call proc_set_exec_trap() to setup child to stop at first instruction. - - * inftarg.c: When using SVR4 /proc interface, call proc_wait() - rather than wait(). - - * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(), - supply_fpregset(), and fill_fpregset(), which are machine - dependent support routines for SVR4 /proc interface. - - * utils.c: Add warning_setup() and warning(). Warning() behaves - the same as error() except that it returns normally rather than - jumping back to command level. Modules that don't want to call - warning() for some reason, but want to produce their own warnings, - can call warning_setup() to ensure compatibility with the way - warning() and error() deal with the terminal. - - * symtab.c: Make internal errors produce more useful messages. - - * tm-68k.h: Move code that is duplicated in almost every single - m68k based machine's configuration files to this common file. - Duplications in the configuration files still need to be removed - (FIXME). - - * infrun.c (child_create_inferior): System V versions must call - setpgrp() with no arguments, to comply with prototyping typically - in <unistd.h>. - - * munch: Add support for SVR4 style nm output. - - * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object - file specific fields from the partial symbol table structure and - replace them with a pointer to private data for each different - flavor of object file reader to initialize appropriately. - -Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com) - - * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c - and previous. - - * mipsread.c (fixup_undef_type): New function. If a struct / - union / enum is defined in a header file but nowhere else used, - (by typedefing, pointer referencing or declaration) the mipsread code - builds the complete tree for the structure but leaves its code as - TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is. - Guess its type based on the details of the members. - -Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com) - - * infrun.c (wait_for_inferior): Check return value from - find_pc_line. - -Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com) - - * infrun.c (wait_for_inferior): fix stepi/nexti that was broken - by my last edit to this routine. - -Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com) - - * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging. - FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap - the values before putting them into the dummy code. (From Peter - Schauer) - -Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com) - - * configure.in: added ebmon target. - -Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com) - - GDB-4.2 release! - - * Makefile.in: Roll VERSION to 4.2. - * README, TODO, WHATS.NEW: Update. - - * core.c (core_open): Improve error message for bad file. - Pass .reg virtual memory address to fetch_core_registers to help - it find the registers in the core-file header. - * coredep.c (fetch_core_registers): Take new argument, use it, - and pass it to register_addr to locate the block of registers. - * xm-mips.h: Update KERNEL_U_ADDR for new scheme.

His ChangeLog - entries are enclosed herein. Not all of these changes - have been merged into the master GDB sources -- check the - ChangeLog above here for the merge log. - -Mon Jun 3 17:05:45 EDT 1991 - - m2-exp.y Created. Tested outside of GDB for a few days. Proper - operators were added, C specific operators and tokens - removed. yylex() revamped to some extent. Still things - missing from the grammar, such as sets. - Tested for two weeks in GDB v3.5. - -Tue Jun 11 17:23:48 EDT 1991 - - m2-exp.y Added boolean constants TRUE and FALSE to the grammar - so they are built-in. Sort of a hack. - -Fri Jun 14 12:53:51 EDT 1991 - - m2-exp.y Added range checking for numeric constants. Any numeric - constant is assumed to be of builtin type INTEGER unless: - (1) it is octal or hexadecimal, in which case it is a - CARDINAL; (2) it is too big to fit into an INTEGER, in - which case it is a CARDINAL. - eval.c Added simple range checking for +, -, and * on integers. - Doesn't work very well for *, since 6 * 1,000,000,000 = - 1,705,032,704, which fails the simple test of result >= - first_operand, no matter in what order the operands are. - -Tue Jun 18 14:11:30 EDT 1991 - - Broke the parser into parts, one containing the C grammar and the other - containing code to be shared by all of the grammars. - - The following files no longer exist: - - expread.y - expread.tab.c - - The following files were added: - - c-exp.y (The C grammar) - m2-exp.y (The Modula-2 grammar) - parser-code.c (Code that is shared by the above grammar) - parser-code.h - parser-defs.h - - Makefile.dist Changed to reflect the above dependencies. NOTE: It is - now necessary to use the Bison compiler compiler, since it - will generate function/variable prefixes other than yy. - -Tue Jun 18 16:47:49 EDT 1991 - - symtab.[ch] Added the external variable working_lang, than holds the - value of the current working language. - Added the ennumerated type language_mode, with the values - language_auto and language_manual, the former meaning that - GDB sets working_lang as needed, and the latter meaning - that the value of working_lang is totally under user - control. - symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL, - REAL, BOOLEAN and CHAR. Also added the type codes - TYPE_CODE_BOOL and TYPE_CODE_CHAR. - utils.c Added set_language_command and show_language_command to - implement the GDB support commands "set language" and - "show language". - expression.h A number of identifiers were added to the type exp_opcode - to facilitate Modula-2 builtin functions, integer - division, and array indexing. - -Wed Jun 19 13:25:58 EDT 1991 - - language.h Added the macro STRICT_TYPE, which evaluates to non-zero - if the language specified by working_lang requires the use - of strict typing of expressions. Eventually, even this - will be able to be changed by the user. - Added the macro RANGE_CHECK, which evaluates to non-zero - if the language specified by working_lang requires the - checking of a value against the domain of its type. - Eventually, even this will be able to be changed by the - user. - language.[ch] Predicates involving types (simple_type, ordered_type, - same_type, integral_type, numeric_type, character_type, - boolean_type, float_type) are added. These predicates are - based on the current value of working_lang, and are handy - in type-checking. - -Wed Jun 19 15:39:34 EDT 1991 - - eval.c Added the function type_array_rank which computes the rank - of an array type. - valarith.c Added the funtion value_bool, which when given a integer - value.h value (ie. struct value *) as an argument, it returns a - boolean value (ie. struct value *) true if that integer - is non-zero, and a boolean value false otherwise. - valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values - will print out properly. - -Wed Jun 19 16:36:34 EDT 1991 - - valops.c Added the function value_capitalize, which returns it - value.h argument capitalized if its argument is a lowercase - letter, or the argument unchanged if its argument is not a - letter. - valarith.c Added the function range_check_p, which returns non-zero - value.h if its value argument is between the integral bounds upper - and lower. - Added the function range_check_enum_p, which makes sure - that its value argument is a valid member of the domain of - its type argument. - Added the function range_check_range_p, which makes sure - its value argument lies between the upper and lower bounds - of its type argument, which must be a ranged type. - Added the function check_array_index, which range and type - checks an index of an array. - Added the function value_multi_subscript, which computes - array[idx1,idx2...idxN], given a value array and an array - of values representing indicies. - values.c Changed value_from_long to work with TYPE_CODE_CHAR and - unpack_long to work with TYPE_CODE_BOOL and - TYPE_CODE_CHAR. - -Wed Jun 19 18:04:08 EDT 1991 - - symtab.c Stored pervasive types in a structure and make - lookup_pervasive_type() a lookup function that was based - on working_lang. If lookup_pervasive_type() returned - non-zero, then that value was returned (a fix, since - before it simply wouldn't return the pervasive type.) - language.h Added the macro CAST_IS_CONVERSION, which evaluates to - non-zero if the language specified by working_lang means - "conversion" when it says "cast". - valops.c Added the function value_real_cast(), which performs a - value.h *cast*, not a *conversion*, which is what value_cast() - does when it can. In particular, - value_cast(<float_type>,4) = 4.0, while - value_real_cast(<float_type>,4) = some mess. - eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR, - parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL. - expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX - and MIN on integral types. *NOTE*: These are currently - hardcoded to work only if there are 8 bits per storage - unit. FIXME. - eval.c Made logical functions call value_bool to return a - properly typed boolean value, based on working_lang. - -Thu Jun 20 11:55:27 EDT 1991 - - valprint.c Types now print out in a Modula-2 fashion. This works for - the cases when the type is printed out step-by-step, that - is, it doesn't work when the name of a structured type - (which includes the keyword "struct", etc.) is simply - displayed. - FIXME: Perhaps this is bad. Parts of it seem to kludgey, - since type specifications in C and Modula-2 are very - different. The C printing of a type is very recursive, - whereas in Modula-2 it is generally very simple. C has - type prefixes and suffixes, which have no real analogue in - Modula-2. Maybe type_print() should call a language - specific type printer. This is also advantageous if we - compile GDB to exclude some of the languages. We'll just - leave those functions out. - -Thu Jun 20 16:57:10 EDT 1991 - - dbxread.c When reading the complete symbol table in (via - psymtab_to_symtab()), the number and types of function - arguments are added to a function type. define_symbol() - calls add_param_to_type() to accomplish this. - Assumption: when we come across a function definition - (N_FUN symbol with an 'f' or 'F' in the name), its - arguments will appear before another function definition. - When a function is found, a pointer to its type is placed - in the global in_function_type. Changes that - add_param_to_type() makes are to this global. - valprint.c The type of a function now includes (for Modula-2) the - types of its parameters. - eval.c Type checking and a check for the proper number of - arguments is now done for function calls. Not sure of the - impact this has on C++ member function yet. - -Thu Jun 20 19:58:48 EDT 1991 - - valprint.c Rewrote the type printer. Broke it into two language - specific parts, adding the functions type_print_m2() and - type_print_m2_1(). - An unfortunate consequence is this: if you debugging a C - program in Modula-2 mode (why?), info types does not work - well with regular expressions, since the types are printed - out in Modula-2 terminology, but stored in C terminology. - language.[ch] Added the functions new_type_last(), type_keyword(), and - type_sep() to aid in the printing of typedefs. - symtab.c Made the printing of typedefs as language independent as - possible through calls to new_type_last(), type_keyword(), - and type_sep(). - -Fri Jun 21 11:50:26 EDT 1991 - - dbxread.c Check all incoming ennumerated types. If it looks like - Modula-2's BOOLEAN type, then change the type_code of the - type to TYPE_CODE_BOOL so we can process it as a boolean - variable. - valprint.c Replaced some of the 0x%x with calls to sprintf and - hexformat() in val_print(). - language.[ch] Added the function hex_to_string(), which converts its - integral argument to a hexadecimal number (format is - language based) and returns the result as a string. - -Mon Jun 24 12:25:07 EDT 1991 - - valprint.c Some functions call type_print_1() directly, instead of - value.h using type_print(), so they can specify where (column) to - print things. Since type_print() takes care of language - dependence, that needs to be called first. Added a - parameter depth to type_print() (so it is now like - type_print_1). Changed type_print to type_print_at, and - made type_print a macro that passes a depth argument of - zero. - symmisc.c Changed all calls to type_print_1 to calls to - type_print_at. - Makefile.dist Made it possible to build GDB for a specific set of - depend languages. Do this by passing a definition for the macro - LANGS to make. LANGS should be a string containing a - space-separated list of language names (ie. LANGS="c m2"). - The default is to build all languages. Note that grammar - files must follow the naming convention of <lang>-exp.y. - gdb.lang This holds the current value of the LANGS macro. It is - examined every time make is called, and is updated if - necessary. - eval.c Added #ifdef _LANG_<lang> to these files. - expread.c Still need to add them to dbxread.c and coffread.c. - main.c - source.c - symtab.c - utils.c - valarith.c - valprint.c - -Mon Jun 24 16:33:11 EDT 1991 - - language.[ch] Added the functions hexformat_pre() and - hex_to_string_pre(), which take a prefix argument to - include in the format string. Thus, hexformat_pre("08") will - return "0x08x" (if the working language is language_c). - Made hexformat() and hex_to_string() calls to the above - with "" as the prefix argument. - - am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c, - dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c, - infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c, - mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c, - pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c, - stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c, - valprint.c, vax-pinsn.c - - Changed all occurences of 0x%[0-9]*l*x in printf format strings to - calls to hexformat() and hex_to_string(). Format strings without - the leading "0x" were ignored. - - depend Updated to take the above into account. - - -Tue Jun 25 15:27:18 EDT 1991 - - symtab.h Added the types range_mode_t, range_check_t, type_mode_t, - and type_check_t to keep track of the current state of - range and type checking. - main.c Added the variables range_mode, range_check, type_mode, - and type_check to record the current state of range and - type checking. Added initialization code to main(). - language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine - the above variables. - - -Tue Jun 25 17:57:08 EDT 1991 - - dbxread.c process_one_symbol() updates the variable (enum language) - source_lang based on the extension of the filename - contained in the N_SO sybmol that started this symtab. - When end_symtab() is called, the value of source_lang is - put into the language field. - stack.c select_frame() sets working_lang (and possibly type_check - and range_check) to the language field of the symtab - associated with the frame that is selected if working_mode - is language_auto. If working_mode is language_manual, a - warning is printed and working_lang is not set. - language.c Added the function set_type_range(), which sets the value of - type_check and range_check (if their modes call for - automatic setting) based on the current value of - working_lang. A non-zero argument will cause the current - settings to be output. - - -Wed Jun 26 14:51:40 EDT 1991 - - eval.c Added range checks on assignment. - m2-exp.y Added the grammar for sets to the language. Currently, - these do not do anything except print an error message. - -Wed Jun 26 17:01:04 EDT 1991 - - m2-exp.y Added the ability for parse_number() to parse negative - numbers. A global flag is set upon encountering a unary - minus. This was done to make, for example, 1 parse as a - CARDINAL, and not as an integer, per Wirth's examples in - Programming in Modula-2 ed.4. - valprint.c Added support for "set radix 2" by then setting - output_format to 't'. - eval.c Implemented range checking on subrange types. Added calls - to range_check_range_p for BINOP_ASSIGN and BINOP_VAL. - Implemented MIN and MAX for ennumerated types. The - minimum value of an ennumerated type is defined by Wirth - as the first identifier, and the maximum as the last. - m2-exp.y Made octal numbers ending with "B" be characters and those - ending with "C" be numbers, per Wirth's book. (p. 34) - -Thu Jun 27 14:11:52 EDT 1991 - - stack.c select_frame() now only sets working_lang, it does not - notify the user. If working_mode is language_manual, then - a warning is issued once. - main.c At the end of each call to execute_command(), working_lang - is checked against the local static (enum language) - current. If they differ and working_mode is - language_auto, the new settings of language, type and - range checking are printed out. - stack.c Modified frame_info() to include the language of the - current frame in the output of "info frame". - language.[ch] Added the function language_str() which returns the name - of the current language. - -Fri Jun 28 15:33:14 EDT 1991 - - m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to - the language. INCL and DECL currently cause an error, - since sets are not implemented yet. INC and DEC are - implemented as PREINCREMENT/PREDECREMENT with one - argument, and as ASSIGN_MODIFY with two arguments. - eval.c Added type checking to the above cases. - value.h Added not_lval_constant to the lval_type ennumerated type. - not_lval_constant means that the value is a constant - value; that is 3 or 'a' or TRUE, not as in a constant - identifier. This is used to help coerce numbers such as 3 - to either signed or unsigned numbers. - valops.c Added the function value_coerce_constants() which coerces - constant integers as following: if one is a constant and - the other is not, the constant's type is set to the type - of the other argument. If both are constants and one is - signed, the other is converted to a signed constant. - -Sat Jun 29 17:26:29 EDT 1991 - - valarith.c Added a better range checker. It now checks range - (successfully) on integral operations [+-] (signed and - unsigned) for any C sized type. Still does not work well - for multiplication.) - int_in_size() returns an integer that is coerced to fit into - specified number of bytes. - -Mon Jul 1 13:04:14 EDT 1991 - - language.[ch] Added the function binop_result_type(), which returns the - builtin (struct type *) type that would be the result of a - binop on the two values V1 and V2. - -Wed Jul 3 19:22:53 EDT 1991 - - source.c Extended source_info() to include the source language in - the output from "info source". - -Fri Jul 5 13:48:52 EDT 1991 - - utils.c Moved the support functions for the GDB set/show commands - dealing with language into language.c. - language.c Added the function language_info(), which displays info - about the current working language, type and range check - settings. Called via the GDB command "info language". - Added an initialization routine _initialize_language(), - that sets defaults for the language, type and range - variables and sets up the new GDB commands. - main.c Language setup moved to language.c. - depend Rebuilt. - -Mon Jul 8 10:10:22 EDT 1991 - - valarith.c Debugged the range checker for arithmetic. Still does not - work for multiplication very well. - -Mon Jul 8 12:40:37 EDT 1991 - - language.[ch] Added the function value_true() which returns non-zero if - its argument represents a boolean true value. - breakpoint.c Changed breakpoint_cond_eval() to call value_true() to - check the truth of an expression. - -Thu Jul 11 12:51:34 EDT 1991 - - language.[ch] Added the predicate structured_type(), which returns - non-zero if the argument is a structured type. - Added the predicate pointer_type(), which returns non-zero - if the argument is a pointer type. - eval.c Added the ability to do addition and substraction on - pointers and integers. This case simply bypasses the - type checker. - -Thu Jul 11 14:41:42 EDT 1991 - - include/stab.def - Added the symbol N_DEFD (0x4a) which is a definition - module dependency that is used by the GNU Modula-2 - compiler and the linker. It is not important to GDB, - except that [dbx|coff|mips]read.c should ignore these - symbols. - -Fri Jul 12 16:07:00 EDT 1991 - - valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) > - 0 in val_print(). Also added statements to the else part - to coerce type (argument to val_print) to a pointer type - if it is an "array of unspecified length". - valops.c Added the function value_m2_string(), which returns a - (value) value which is a constant string, whose type is - (ARRAY [0..n] OF CHAR). The length field of the type - structure is set to zero, so it will be interpreted as an - "array of unspecified length". - stack.c Moved the language/frame mismatch check to - main.c:execute_command(). - main.c The working language is recorded each time - execute_command() is executed. If working lang has - changed during its execution, then the new - language/type/range info is printed out for the user. If - the working language does not match the language of the - frame, a warning is issued. - -Sat Jul 13 16:16:39 EDT 1991 - - eval.c Moved all the type-checking stuff for operators to - language.[ch] language.c. This is so we can keep language-specific - stuff (like for what type operators are defined) in - language.c. - language.[ch] Added the function binop_type_check(), which checks to see - if its two (value) arguments are type-compatible with its - opcode argument. The opcode should represent an operation - involving an operator. Also added the macro function - unop_type_check, which calls binop_type_check with a - NULL second argument. - expprint.c Added Modula-2 operators to the op_print_tab, so info - expression.h break works correctly. Also added "op_string", which - returns the string corresponding to the (enum exp_opcode) - opcode that is its argument. - - -Sat Jul 13 18:26:18 EDT 1991 - - coffread.c Added code to record the type of function arguments with - each paricular function. Code is very similar to that - added to dbxread.c. - dbxread.c Moved add_param_to_type() to symtab.c - symtab.[ch] Added function add_param_to_type() from dbxread.c - - *** NOTE: The above additions have not been tested. - -Mon Jul 15 12:50:47 EDT 1991 - - langauge.[ch] Added the functions type_error and range_error, which work - like error() except if the type/range mode is set to - *_mode_warn, then they do not do a return_to_top_level(), - but merely print a warning. - Also changed [set|show]_[type|range]_command() to support - the new "warn" feature. - -Thu Jul 18 17:50:54 EDT 1991 - - mipsread.c Added code to record the type of function arguments with - each particular function. Code is very similar to that - added to dbxread.c. - - *** NOTE: The above additions have not been tested. - -Fri Jul 19 11:19:10 EDT 1991 - - defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and - UMIN_OF_SIZE, which when given a size of a numeric type, - return the maximum and minimum value it can hold. UMAX... - and UMIN... return the result for unsigned types. - symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on - struct types.

This (somewhat) fixes display of - expressions that include misc_function_vector names. Try `cond 1 - !strcmp("a","b")' then `i b'. - - * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume(). - The child can be proceeded from inside wait_for_inferior in - evaluating breakpoint conditions, and DO_DEFERRED_STORES was - getting skipped in that case. - - * expprint.c (print_subexp): Use filtered output, since the - subroutines we call use it, otherwise the output is horribly - mangled, since output of wrappable stuff comes out late. - - * Makefile.in: Bump VERSION to 3.98.1 - - * infrun.c (child_create_process): Use execlp to find the - shell to exec our target program.

Assume that alldeps.mak and depend are already built in - srcdir, and avoid running "make" (particularly "make depend", - which involves "gcc") from inside configure. Build Makefile - directly rather than building Makefile.conf first. - * configure: Regenerate with above changes. - * Makefile.in: Use $(BISON) to find bison. Roll VERSION - to 3.98. Revise gdb.tar.Z procedure to produce a file - called gdb-$(VERSION).tar.Z but which unpacks into a - directory called "gdb". Move non-source files out of - $(SFILES_SUBDIR). Pretty up alldeps.mak with comments. - (depend): Don't try to do "gcc expread.y". - (expread.o): Update dependencies by hand. - -Mon Jul 29 15:21:09 1991 Roland H.

Pesch (pesch at cygint.cygnus.com) - - * doc/gdb.texinfo: - (1) Applied some fixes due to comments from Larry Breed (easier ones - through chapsec 5.2) - (2) Eliminated use of @footnote---had my doubts about it anyways, and - it's broken in latest texinfo - (3) Introduced *some* use of [] for optional arguments, where - explanation is not simpler by listing cmd w arg and cmd w/out arg - separately. Still not using @deffn. - (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a - couple of headings are too long. Need patches to texinfo or revision - to GPL-2. - - * Partial update to README (which still needs work for this - release!): (1) use of configure corrected for new script, - (2) "make gdb.dvi" and "make gdb.info" mentioned. - -Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com) - - * symtab.c (lookup_symbol): Don't complain right off about - no debug symbols; use the misc function vector first. - (list_symbols): Use misc function vector to find symbols - that don't have debug info, and print them. - (find_pc_symtab): Temporarily avoid fatal() when psymtab - PC range doesn't match symtab PC range, as it does on the - MIPS because our symtab reading isn't perfect. - - * dbxread.c (dbx_symfile_read): Make warning about - "no debug symbols" slightly nicer. - - * source.c (select_source_symtab): If "main" symbol exists, - but decode_line_spec can't find line info, don't just return - a zero; try other source symtabs or give an error. - - * mipsread.c (parse_partial_symbols): Sort the psymtabs by - their low addresses first, then rip through fixing high addrs. - - * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd, - <runene@ifi.uio.no>. - (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef. - -Tue Jul 23 18:52:43 1991 Roland H.

This code - is not the problem, the problem is in parse_fdr where the psymtabs - are set up. - (cross_ref): Result should indicate that we used one aux entry - normally, or two if we encountered a "next" entry. This used - to leave the caller pointing at the wrong aux entry. - (add_symbol): If overflowed cur_block, reallocate it larger, - chase all pointers to it, and complain(), rather than clobber memory. - (shrink_block): Use xrealloc rather than xmalloc-and-copy. - (new_field): Only allocate one field initially, not two. - Pull ++ out of macro argument.

Allocate and parse - static symbols as well as external symbols. FIXME, enum values - are not handled in this pass, but should be. Inline new_psymbol. - Use SYMBOL_VALUE_ADDRESS. - (psymtab_to_symtab_1): Read symbols into global static block - by default (until enter some function's local block context). - (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK. - (destroy_all_symtabs, new_psymbol): Eliminate, unused. - - * source.c (select_source_symtab): Select a source symtab - from either the symtabs or, failing that, the psymtabs. - (list_command): Update error message. - (forward_search_command, reverse_search_command): Use getc, not - fgetc, for speed. FIXME, add comment about buffers that die if - overrun by long line. - - * values.c (unpack_field_as_long, modify_field): Avoid shifting - by an entire word, which is not portable, if we have a 32-bit - field.

Pesch (pesch at fowanton.cygnus.com) - - * Makefile.dist, doc/gdb.texinfo: respectively create, and use, - the new target "rdl-apps.texinfo" which captures the Makefile - variable that records where to find the Readline libraries. - -Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com) - - * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h". - * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters. - * defs.h (const, volatile): Only define if not already defined. - * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud. - - * README: Update for release 3.95. - * config.gdb: Don't create readline dir in subdir builds. - * main.c: Include with "..." form for non-system include files, - so "gcc -MM" for "make depend" works. - Include readline files with "...h" rather than <readline/...h>. - * mipsread.c: Include "ecoff.h" rather than "intel-coff.h". - - * coffread.c: Undo minor damage done by Rich Pixley. Use - different internal and external representations of COFF - data structures. Use new BFD routines for swapping them in and - out. - * symfile.c (free_named_symtabs): Avoid freeing file names that - are null or empty. Old i960 tools seem to produce files that - claim to have empty names, causing each successive file read - to blow away the previous one. - * sparc-xdep.c (deferred_stores): Repair minor damage by Rich. - Move deferred_stores to top of file, but don't separate its - #define's from its variable.

These are ordinary info - files, formatted from gdb.texinfo (via gdb-all.texinfo, see - Makefile)---but due to use of texinfo 2, can't count on makeinfo - to generate these, so we distribute them already formatted. - - * gdb.texinfo: included full Info node and menu crud (as generated - by C-u M-x texinfo-master-menu using the texinfo-2 elisp code). - - * Makefile: updated "gdb.dvi" target to use M4 preprocessor; - put in comments-for-future gdb.info target (one day makeinfo will - work again). - -Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com) - - * gdb.texinfo: Updated to include new or old undocumented - commands, at least the following (perhaps some others I forgot to - record): info f, info float, info path, info program, info s, info - set, info source, info terminal, info types, info user, set/show - print object. - Also covered all recent GDB command renames for v4. - -Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com) - - * mipsread.c: Rather than keeping count of how many symtabs - and psymtabs we have, for sorting purposes, count them when - we need to sort.

Don't repeat it. - * remote-nindy.c (nindy_detach): Don't need dont_repeat() now. - * expprint.c (print_subexp): Avoid switch fallthru on - BINOP_ASSIGN_MODIFY, so we can print += and such. - * frame.h: Fix typo. - * inflow.c (kill_command): After killing inferior, print our - current frame in the core file, if we have one. - (generic_mourn_inferior): When inferior dies, either select - the current frame (in the new target, e.g. core file), or - set both the current and selected frames to NULL. - - Changes from Peter Schauer. - - * infptrace.c: Avoid <sys/ptrace.h> on USG. - - * Make all file names fit in 14 characters (sigh and damn!): - mv hp300hpux-xdep.c hp300ux-xdep.c - mv symmetry-xdep.c symm-xdep.c - mv symmetry-tdep.c symm-tdep.c - mv convex-opcode.h convx-opcode.h - mv tm-vxworks960.h tm-vx960.h - mv tm-vxworks68.h tm-vx68.h - mv Makefile.srcdir Makefile.sdir - mv gdb-int.texinfo gdbint.texinfo - mv remote-sa.m68k.shar rem-m68k.shar - mv remote-multi.shar rem-multi.shar - * Makefile.dist, README, config.gdb, convex-pinsn.c, - tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68, - xconfig/hp300hpux, xconfig/symmetry: Change names to shorter - names. - - * command.c (user_info_1, user_info): New command for listing - the user-defined commands. - -Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com) - - * dbxread.c (really_free_pendings): Clear file_symbols - and global_symbols after freeing them; otherwise, running - this function twice (if it appears twice on the cleanup - chain), we try to free things twice. - - * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr - based on text_addr (the address of text in core), not on addr (the - offset between text in the .o file and in core). This change - is from Peter Schauer. - - * main.c: Define ALL_CLEANUPS as a cast of zero. - (return_to_top_level): Use it. - (main): Do all cleanups after each command run as part - of the gdb startup sequence. Also do all cleanups before - entering the command loop, and every time we exit the command - loop and reenter. Before, the cleanups from the startup sequence - were being left undone until the first error! - (command_loop): Rename do_nothing cleanup to command_loop_marker - so we can see it easily when examining the cleanup chain. - (init_signals): Add another do_nothing for signal handling. - (quit_command): Only try to kill target if it has execution. - Problems in the target stack got us into a state where - inferior_pid was nonzero but none of the targets had execution. - In this state you couldn't exit gdb. - - * dbxread.c: Two changes from Peter Schauer. - (echo_command): Fflush output after an echo command. - (show_history): Pass all args to cmd_show_list. - - * utils.c (init_malloc): Call mtrace to turn on tracing - if the environment variable MALLOC_TRACE is set to a file name. - * mtrace.c: Add source file which provides a log of every malloc, - free, and realloc to a trace file. - * mtrace.awk: Add source file which analyzes the trace file. - * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}. - (VERSION): Roll to 3.94.3. - - * breakpoint.c (breakpoint_1): Add a space to "i watch" output. - (check_duplicates): Don't bother with watchpoints. - (set_raw_breakpoint): Comment about danger of this routine. - (watch_command): Parse and eval all args before calling - set_raw_breakpoint. - - * solib.c (find_solib): Avoid error in referencing memory to - see if any more shared libraries have been added. This is - particularly useful if the target has terminated. Bug reported - by Peter Schauer. - - Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de> - in bringing up 3.94.2 on the Sun-3. - - * Makefile.dist: Include CFLAGS in rule for cplus-dem.o. - * breakpoint.c (enable_breakpoint): Check for valid watchpoint - expression (in scope) before reenabling watchpoint. - * signame.c (init_sigs): Add missing declaration of i, fix - sys_siglist declaration. - * source.c (list_command): Fixed range computation to use - lines_to_list (). - * stack.c (backtrace_command): Do not allow command if target has - no stack, print informative error message. - * target.c (target_command): Do not write into command line - because this fails if the target command is used in a user defined - command. [This change was enhanced by gnu to support any- - unique-prefix matching on target names.] - * valops.c (value_struct_elt): Avoid infinite loop on an - erroneous attempt to print the member of function (try p main.p). - -Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com) - - * expread.y (name_no_typename): Avoid reduce/reduce errors - caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT. - Since the GDB parser really doesn't use name_no_typename in a - name-only context, the parser can't tell the diff between - names and numbers here. Avoid allowing a name_no_typename - to be a NAME_OR_*INT to resolve the conflict. - -Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com) - - Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c): - - * valprint.c (val_print_fields): bitfield printing didn't handle - byte order. Indirect through a few more fns to cope. - - * values.c (modify_field): also cope with byte order. - -Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com) - - Cleanup for release 3.94.2: - - * Makefile.dist: Pull REMOTE_OBS. 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. PATH, G960BASE, G960BIN for starters. - * source.c (mod_path): New function, from guts of - directory_command, modifies a path. 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.

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.

Use printf, not fprintf, when not passing a file - pointer... - (compare_opcodes): Check that identical instructions have - identical opcodes, complain otherwise. - - * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This - was reported by Roland McGrath. - (unimp): Only match if exactly zero instruction.

Changed callers. - - * stack.c (frame_info): Use filtered output, and indicate wrap - points. Remove kludgy formatting designed to avoid line wrap. - - * utils.c (wrap_here): If the line is already full (because - we had printed a long indent or long wrapped string), do an - immediate newline-and-indent. - - * m68k-pinsn.c (print_insn_arg): Bugfix from - ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0' - instruction is incorrectly disassembled as bkpt #8. - - * dbxread.c (end_psymtab): Bugfix from Peter Schauer - <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a - breakpoint in a *.y file gdb will say Reading in symbols for *.y... - and then will dump core (sometimes). I traced it back to an - uninitialized symfile_name in psymtab_to_symtab. - (const_vol_complaint): Add quotes to message. - (define_symbol): Only believe line number if gcc_compiled. - Avoid allocating symbol if we will not return it. - - Add target strata support so that newly established targets go - into their right place in the target stack (e.g. a new exec file - doesn't wipe out the ability to access the running process). - - * target.h, core.c, exec.c, inftarg.c, remote-eb.c, - remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum - and initialize it properly in all the targets. - - * target.h: Document strata. Change return type of push_target. - - * target.c (nomemory): new function for dummy memory access. - (tcomplain): Rename complain, now also used in symfile.c. - (push_target): Push targets within strata.

Change doc of -q since - gdb no longer prints the copyright and blurb if you specify a file - name to be debugged (just like Emacs). Add doc for Nindy-specific - command line flags for specifying target serial port and such. - Update copyright to 1991. - - * gdbcore.h: Remove a large mass of now-useless crud, since BFD - has taken over for us the job of ripping up executable files. The - crud caused Per Bothner's port to not compile. - - * infrun.c (normal_stop): Avoid printing "Program exited - normally" if we are in batch mode. This allows a GDB which - executes a program on a target system, to behave like a Unix - command (input from stdin, output to stdout, no extraneous - output). - - * main.c (main): Allow additional machine-dependent command line - options to be specified with the ADDITIONAL_OPTIONS, - ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and - ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent - processing to occur just before the main loop with - BEFORE_MAIN_LOOP_HOOK. - (main): If a "core file" argument is specified, and it is not a - core file, try it as a process ID to attach. - (symbol_completion_function): Attempt to cope with - "show screen-" TAB, not very successfully. This needs more work, - FIXME. - (batch_file): New function, returns whether we are reading - commands from an interactive tty on stdin, or from somewhere else. - Called by normal_stop since it doesn't get from_tty passed down - to it like many commands do. - - * remote-nindy.c: Handle command line options for nindy - connection. - (nindy_before_main_loop): Prompt user for tty name if they - don't specify it before getting to the interactive command loop. - - * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk, - and -r command line options. Also add hook before main loop - to make it easy to specify a tty. - - * TODO: More things to do, one done. - -Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com) - - * dbxread.c: Make complaint() calls pass pointer, not struct. - Add complaints about badly formatted C++ type information - (const/volatile indicator, and parse errors resulting in - error_type). Fix C++ virtual member fn comment. - (read_struct_type): Avoid bumping pointer if we got a parse - error; this prevents our walking beyond the end of a string. - Terminate loop on null char as well as semicolon. - (process_one_symbol): Fix the LBRAC fix so that it uses the - last previous SLINE, FUN, or SO record's PC address. C++ debug - symbols did not have SLINE records in a useful order compared - to the LBRAC records. - (define_symbol): Handle "catch" records. - - * symtab.c (check_stub_type): Added new complain - `stub_noname_complain' and added a consistency check to - keep the debugger from crashing when finishing from an - exception frame.

Turned out that the - problem was the SunOS 4.1.1 (and previous) C compiler outputs - the LBRAC symbol with an address in the *data* segment, which - blew our binary search through the blocks. - - * dbxread.c: Use the complain() facility consistently to bitch - about problems in the symbol file we are reading. - (finish_block): Add code to check the nesting of the blocks; - complain and Procrust them to fit if wrong. - (make_blockvector): Check the order of the blocks, complain - [but don't cope] if wrong. - (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC - symbols to be sure their PC value is greater than the last SLINE - (line number) symbol we've seen, complaining and adopting the - SLINE PC value if wrong. - - * symfile.h (struct complaint, complaint_root, complain, - clear_complaints): Add. - * symfile.c (complain, complaint_root, clear_complaints): Add - facility to deal with non-fatal complaints and to regularize their - suppression. - (symbol_file_add): Clear complaint counters to allow new complaints. - (initialize_symfile): Add 'set complaints' and 'show complaints'. - - * dbxread.c (dbx_symfile_read): Remember the address and size - of the string table for the main symbol file, so we won't read it - more than once. - (dbx_psymtab_to_symtab): Fix the check for main symbol file, - to avoid reading the string table yet again. Lint. - (throughout): Improve filtered output, including word wrap. - (read_range_type): Improve Bothner's fix to handle other types too. - - * utils.c: Improve line wrap implementation. Handle unlimited - width by making chars_per_line unsigned. - (puts_filtered): New, easy, function. - - * defs.h (puts_filtered): add. - - * mipsread.c (compare_symbols, sort_symtab): Remove these fns, - call the identical sort_symtab_syms() in symfile.c instead. - - * expread.y: Suggest the `file' command rather than `symbol-file'. - - * command.h (enum var_types): Add zinteger for seroable - unsigned integer. - * command.c (do_setshow_command): Handle var_zinteger. Restructure - nested if's into a switch. - - * breakpoint.c (bpstat_print): If bpstat "print" flag is not set, - we did not stop because of a breakpoint (it must have been for - some other reason, like a "stepi"), so don't print anything. - - * symtab.c: Include <sys/types.h> all the time. Now that BFD - doesn't include <sys/types.h>, old SunOS's require it for - <sys/stat.h>. - -Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu) - - A test port of gdb-3.92.6 to the Sony NEWS. - - * Makefile.dist - Don't normally link in remote- or vx stuff. - Some of it doesn't compile, and it wastes space for 99% of the users. - Remove reference to no-longer-used HAVE_VPRINTF. - Fixed BFD_DEP typo to BFD_DIR. - * dbxread.c - Fix cast in arg to bfd_h_getlong. - Make char *prefix be const. - Fix how certain range types are mapped into builtin unsigned int types. - * infrun.c - Remove 2 #includes. They cause errors (on Sony, at least), - and aren't needed (they wern't in earlier versions). - * printcmd.c - print_address_symbolic should never demangle labels - (since it prints *assembler-level* labels). - - [This was superseded by the change to printcmd below.] - - * utils.c - Add some "volatile" return types to avoid warnings. - If MISSING_VPRINTF add vprintf function and not just macro - (since vprintf is used in printcmd.c). - * valprint.c - Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow. - (The latter isn't grokked by some PCC-based compilers.) - - [This change is in abeyance, we prefer to fix obstack_ptr_grow.] - - Make chunk size of dont_print_obstack 32*4 instead of default 4096. - * nindy-share/coffstrip.c - Added some forward declarations (otherwise, gcc complains - about implicit extern redefined as static). - -Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com) - - Changes inspired by Per Bothner: - * printcmd.c (print_address_symbolic): Take additional parameter - specifying whether to demangle. - (print_address): Pass in asm_demangle to control demangling. - (print_address_demangle): New fn, takes explicit arg to control - demangling. - * utils.c: Add new vars demangle and asm_demangle, and let them - be set and shown. - (fputs_demangled): If !demangle, just print the argument. - (fprint_symbol): If !demangle, just print raw symbol. - * valprint.c (val_print): Call print_address_demangle rather than - print_address, to cause demangling to depend on the global - rather than assembler-level demangling setting. - * WHATS.NEW, gdb.texinfo: Document. - - * main.c (show_command): Show all settings if no arg. - (initialize_main): Make "info set" the same as naked "show". - * command.c (cmd_show_list): Handle prefix commands in the - list, and print the name of the setting as well as its English - description and value. - - Allow gdb functions to specify where a line should wrap if it - exceeds the size of a terminal line.

This really - needs to be generalized to a timestamp per file. - - * core.c (cleanup_core): Avoid coredump if no core file. - - * config.gdb: Accept -host or -target in place of +host or - +target. - - * coffread.c (find_linenos): Avoid desupported BFD interface - to line numbers. We still read them manually rather than using - BFD's "generic" features. - - * gdbrc.tex, threecol.tex: Add GDB reference card and its - formatting code. - Makefile.dist: Add refcard to OTHERS list for creating tar files. - - * Makefile.dist: Eliminate use of $< in explicit targets. - - * readline/Makefile: Use $< rather than $*.c, which does not - include the VPATH in GNU Make. - - * tconfig/i960-bout, tconfig/i960-coff: These are identical - copies of tconfig/i960, added for global configuration - compatability. All i960 versions can read both coff and b.out. - - * tm-88k.h: Fix multiline macro that lacked \'s. Remove - COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled - automaticaly. - - * TODO: Think of more things to do. - -Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com) - - tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config - of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to - 64-bit float conversion. - - tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make - equivalent to sun?os4 so global config works. - -Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com) - - Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de> - - * main.c: Only declare linesize once; declare pagesize not at - all, since it is never used. - (main): Clear newly allocated line before it is used. - -Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint) - - Further stabilization for the Intel 960. - - * Makefile.dist: Parameterize the location of the "include" - and "bfd" directories, as well as "getopt". Add symfile.c. - Link in both dbxread and coffread. Fix up "make depend" to - rewack the locations of include, bfd, and getopt in its output. - - * README: Document moving include files, improve some of - the other doc. - - * coffread.c: Move common code out to symfile.c. Change - symbol_file_command style interface to use new *_symfile_init - and *_symfile_read interface under BFD. Use BFD internal - info to locate line table, symbols, etc. - - * core.c (core_fetch_registers): Rename to get_core_registers - to avoid confusion with fetch_core_registers. - (register_addr): Move to coredep.c, which is already machine - dependent. This leaves core.c pretty clean of dependencies. - - * coredep.c (register_addr): Accept this routine from core.c. - - * dbxread.c: Move common code (with coffread.c, etc) into new - symfile.c. Each psymtab now contains a pointer to the - format-dependent function that knows how to read it in. Make - some things static. - (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2. - (process_one_symbol): Add code to complain about a "compiler bug - we muzzle here", if we actually see it. - - * eval.c (evaluate_subexp): Insert missing "break" statements - in code that determines whether a variable is an lvalue in - memory, register, or whatever. I detected this via a compiler - bug in which it *almost* mashed out the whole switch statement. - - * gdb-int.texinfo: Add minor sections on configuring gdb for - release, and about the README file. - - * infcmd.c (registers_info): Fix formatting somewhat. Still - not as pretty as before, but it handles byte swapping. - - * remote-nindy.c: If data cache routines are interrupted while - waiting for the remote end, be sure that any uninitialized cache - blocks are on the free list, not on the valid list! - - * symfile.h: Flesh out this header file with all the various - routines and variables that have been merged in from dbxread.c - coffread.c, and symtab.c to symfile.c. - - * symfile.c: New file, containing code common to dbxread.c, - coffread.c, and some code from symtab.c. All generic code for - reading symbol files should be in here now. - (unrecord_misc_function): Remove unused function. - - * symtab.h: Remove file-reading things to symfile.h. - - * symtab.c: Remove file-reading things to symfile.c. - - * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL - to decode i960 fault types. - - * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c, - target.c: Change type of the "resume" function from int to void, - since its result was never used. - -Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint) - - * main.c: Replace "stupid" with "caution"; you now "set caution - on or off". - - * printcmd.c (print_scalar_formatted): Fix typo in 'g' format - - * infcmd.c (do_registers_info): Call val_print to deal with the - byte order of the registers being printed. FIXME, this makes - the formatting of the output uglier. - - * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is - defined, call it for signals the debugger doesn't itself use. - The i960 uses this for more detailed fault information. - - * remote.c (remote_open): If arg is null, print help rather than - dumping core. - - * sparc-xdep.c (register_valid): Avoid declaring size, since - various modules will think of various sizes depending on the - architecture of their tm-file. FIXME, we need protection against - actually entering one of those modules, which would clobber - storage if not for the target architecture compiled into gdb. - - * stack.c (up_command, down_command): Always print the frame - you arrive at. - (up_silently_command, down_silently_command): New commands - for use in scripts. - - * i960-pinsn.c (reg), i960-tdep.c: Lint. - - * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes - more parameters than it used to. - - * findvar.c (registers): Increase slop to 256 bytes, which should - protect us against even most RISC machines with large register - sets. - (locate_var_value): Move declaration inside related ifdef. - - * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP - throughout, to avoid throwing away buffered input from the board. - (nindy_wait): Supply_register takes addr_of_value, not value. - (i960_print_fault): Renamed from i80960_fault. - (nindy_fetch_registers): Avoid have_regs stuff, just get them. - (nindy_store_registers): Avoid regs_changed stuff, just stuff - them. - (nindy_create_inferior): Don't bother to write PC_REGNUM since - we can set the PC in the call to proceed(). Unpush nindy_ops - before pushing it on top, to avoid message to user. Eliminate - commentary from Unix machines that just misleads here. - (reset_command): Fix error message to suggest target command. - -Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint) - - Release 3.92.5 as frozen. - - Stabilize the merged release...with help from lint, Saber C, - gcc -W, etc. - - Everywhere: Add include files needed to declare return types - of functions called. - - * gdb.texinfo: Roland Pesch is documenting gdb, glory be! - - * breakpoint.h: Add undeclared breakpoint functions, and some - functions for display handling since I couldn't think of a better - .h to put them in. - - * breakpoint.c (insert_breakpoints): Make code for disabling - shared library bkpts more likely to work. It's used when we - rerun a program and stop before the shared library has been - mapped in. - (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int, - cast from pointer, so it squeezes through catch_errors. - (bpstat_stop_status): Fix logic broken some time ago. We now - always create a bpstat if the stop address matches a breakpoint, - even if we don't stop there -- just like the old code used to do - before I got my fingers into it (sigh). - (breakpoint_1): Print "ignore count" after "stop only if" - condition, since that's how it actually works. - (mention): Handle watchpoints as well as breakpoints. - (watch_command): use set_raw_breakpoint and mention to do most - of the work (and initialize all the fields!). Only pass one - arg to parse_c_expression, since that's all it takes. - - * command.c (not_just_help_class_command): Rename arg to args - since we ignore "unused argument" warnings on vars named "args". - inflow.c (child_terminal_info): ditto. - infptrace.c (kill_inferior): ditto - main.c (catch_errors, version_info, quit_command, pwd_command, - source_command, dump_me_command, editing_info, - set_history_size_command, set_history, show_history, - set_verbose): ditto - stack.c (locals_info): ditto - target.c (target_files_info): ditto - valprint.c (set_input_radix, set_output_radix): ditto - - * core.c: Remove old variables for handling core and exec file - sections (data_start, data_end, stack_start, stack_end, - reg_stack_start, reg_stack_end, reg_stack_offset, text_start, - text_end, exec_data_start, exec_data_end, text_offset, - exec_data_offset, data_offset, stack_offset). They're - superseded the more general build_section_table and - xfer_memory. - (get_exec_file): Mention the `file' command. - (read_memory_check): Rename to memory_error, and only call it - in the case of an actual error. - (read_memory, write_memory): call memory_error. - (core_fetch_registers): Register section name is ".reg". - - coredep.c: Remove a bunch of crud now that all this file does - is pull the registers out of a core file. - (fetch_core_registers): Rewrite to actually work, I hope. - - dbxread.c: Use a.out.gnu.h, not system a.out, now. - Replace index() with strchr(). Remove all the pre-BFD macro - definitions for accessing the symbol file. - (struct dbx_symfile_info): Encapsulate the information that - dbx_symfile_init needs to pass to dbx_symfile_read in this - struct. - - (dbx_new_init, dbx_symfile_init, dbx_symfile_read, - dbx_symfile_discard): Rearrange symbol file reading to divide - the format-specific part from the format-independent part, - leaving the format-independent part such as file name expansion - and opening in symtab.c. This replaces - partial_symbol_file_open and partial_symbol_file_read. - Symbol_file_read, add_file, add_file_target_command, - add_file_addr_command move to symtab.c. Pass an explicit - "mainline" flag for when reading the main symbol table, rather - than relying on the offset address to be zero or nonzero. - - (dbx_symfile_read): Don't allow void *'s to be printed as - typedefs. - (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols. - (ADD_PSYMBOL_TO_LIST): Make the "function call rather than - macro" debug version really work. - (read_dbx_symtab): Remove unref'd parameter inclink. - Avoid swapping N_SLINE symbols, for speed. - Merge N_TEXT!N_EXT case with the other external symbol - definitions' case. Add comments. - (start_psymtab): Allocate the symfile name in the psymtab on - the psymbol_obstack, rather than using the caller's storage. - (end_psymtab): Only allocate a dependencies list if there are - more than zero. - (psymtab_to_symtab_2): Use BFD when reopening file to read - its symbols for real. - (read_struct_type): Add FIXME comments where it needs work - for C++ bogosity. - (read_huge_number): Add FIXME about overflows. - (read_range_type): Add FIXME about comparing a long to 1<<32. - - * coffread.c: Minor changes to move things closer to the new - regime with symtab.c and dbxread.c Major work is still needed - here. - - * exec.c (exec_file_command): Remove old variables (see core.c - above). - (xfer_memory): If memory transfer is right at the end of a - section, don't lose. - - * findvar.c (get_saved_register): If value is in a real - register, LVAL is lval_register, not lval_memory. - - frame.h: Declare print_sel_frame and record_selected_frame. - - gdb-int.texinfo: New file, for GDB internals documentation. - Very simple, unformatted doc of cleanups is there for now. - - gdbcore.h: Remove obsolete variables that described a.out - section addresses and offsets. (See core.c above.) - Declare fetch_core_registers and registers_fetched. - - getopt.c: Declare char *alloca(); even on SPARC. - - infcmd.c (run_command): Call target_kill rather than - kill_inferior. - (step_command, next_command, stepi_command, nexti_command): - Declare from_tty parameter even though we don't use it. - (run_stack_dummy): argument BUFFER is a char array, not - a pointer to REGISTER_TYPE. - (finish_command): using_struct_return needed a value *, - not a struct symbol *. - - * infptrace.c (child_xfer_memory): To avoid dependency on - where sections are in memory, try PT_WRITE_D and if that fails, - try PT_WRITE_I. Most Unixes don't care which you use. - - * infrun.c (step_resume_break_shadow): Change to array to - match other breakpoint shadow storage. - (clear_proceed_status): Pass address of bpstat to - bpstat_clear, not the bpstat itself. - (child_create_inferior): FIXME comment about if the child - exits. - (start_inferior): Remove old function. - (child_open): Use target_kill rather than kill_inferior. - (wait_for_inferior): Ditto. - (insert_step_breakpoint, remote_step_breakpoint): Use - new step_resume_break_shadow. - - * inftarg.c (child_wait): If all child processes die, - pretend that the one being waited for exited with signal 42. - - * main.c (command_line_input): When scanning for comments, - don't coredump on unclosed quotes. - (quit_command): Use target_kill rther than kill_inferior. - (_initialize_main): Rename class_user from "user" to - "user-defined". - - * printcmd.c (print_command_1): Initialize "fmt" if no format - is specified by the user. - (print_frame_args): Only add to args_printed if we are - actually fetching args from the stack (avoiding undefined - arg_size). - (_initialize_printcmd): Remove bogus \{ from string. - - * remote-eb.c (eb_open): Avoid coredump on no argument. - - * remote-nindy.c: Bring out of Intel environment into new - target environment.

Print program counter - register's actual name rather than "pc", since it's called the - "ip" (instruction pointer) on the i960 (sigh). - - * target.c (target_command): Add command for selecting a target - type and calling its open routine. This is used for initiating - communication with a particular target, in a generic way. - - * tm-i960.h: Update for modern gdb. Remove semicolons from - various macros.

Uses - RPC routines that are shared with the target system, in directory - ${srcdir}/vx-share. - - remote.c: Vectorize remote interface. - - source.c: Globalize source_path, and make an alias "l" for "list" - since we now have the "load" command. - - sparc-xdep.c: Use new param-no-tm.h. - - symmisc.c (free_named_symtab): Add new function from Wind River. - However, ifdef it out for now while we think about what it should - really be doing. - - tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move - PREPARE_TO_STORE to - the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since - non-Unix-children handle this with their own code in the target - transfer vector. - - Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to - source and target lists. Add vx-share to default list of include - directories. Add new files to src and target lists: mem-break, - target, inftarg, remote-eb, remote-vx, targ-vx.

In some - places it was used as a flag, in others as a stack level (?). - - * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the - default is to use the portable (vprintf) version rather than the - kludge version. - * xm-news.h (MISSING_VPRINTF): Add. - - * valprint.c (val_print): Demangle fancy vtbl printouts. Lint. - -Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint) - - * Remove stuff that forces -Bstatic linking of gdb, and warnings - about linking debugged programs -Bstatic in the sun?os4 config - files in tconfig and xconfig subdirectories. - - * main.c (main): Remove unreached exit(0) now that we exit - via quit_command(). - - * Create TODO file for online bug list. There are too many - "little" bugs to keep track of on paper. - - * Change Projects file to refer to bug-gdb@cygnus.com - rather than kingdon@ai. - -Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint) - - * Makefile.dist (VERSION): 3.91.4 now. - - * symtab.c (init_misc_bunches): Rename from init_misc_functions. - (condense_misc_bunches): Add sanity check that misc_count is - the same as the number of symbols in the bunch. - - * coffread.c: rename init_misc_bunches. Pass an argument - to condense_misc_bunches (a zero). - - * dbxread.c (partial_symbol_file_read): Call init_misc_bunches - every time we are called; don't rely on our caller to do it. - (add_file): Remove call to init_misc_bunches. - - * mipsread.c: Only warn, don't error, if unknown symbol types. - This keeps an old gdb from falling on its face if it sees newly - extended symbol info. Rename init_misc_bunches. - -Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint) - - * Merge in changes from Per Bothner for DECstations and other - MIPS stuff. 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. FIXME. - - * dbxread.c: Fix thinko using strcmp. - (init_psymbol_list): declare static. - (partial_symbol_file_open): Comment cleanups better, avoid - cleaning up the string table since the caller will do that. - Move the stat for mod time into symbol_file_command, temporarily. - (There should be a mod time for each symbol file, eventually, - to control its rereading. FIXME.) - - * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for - SunOS, which gives error for shared libs otherwise. (From - Schaefer, probably FIXME needs work for portability.) - - * solib.c: Move #include "param.h" to work. - Lowercase all the Uppercase Letters In the Messages. - (find_solib): Clean up inferior_so_name for debug printouts. - Allow no argument, to mean all shared libraries. - - * symmisc.c: include param.h to get CLEAR_SOLIB. - -Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint) - - * Merge in Kingdon's changes from FSF: the diffs from 3.90.9 - to 3.90.11.

No callers need the stop_bpstat - between clear_proceed_status and proceed. - - infcmd.c: Add breakpoint_proceeded definition and comment. - (cont_command, jump_command, signal_command): Move call to - clear_proceed_status right next to call to proceed. - - breakpoint.c (bpstat_do_actions): Avoid clobbering our - caller's argument while running down the chain of breakpoints. - Use new variable "breakpoint_proceeded" to determine when - a command that it executes moves the inferior past the - breakpoint. - (bpstat_clear): Handle NULL argument. - (bpstat_clear_actions): Avoid useless call to - breakpoint_auto_delete. - (delete_breakpoint): Clean up bpstat's that are pointing to - the deleted breakpoint from the stop_bpstat chain. - (breakpoint_auto_delete): Simplify. - - * Clean up handling of EOF, error on stdin, etc. This was - prompted by a network problem that caused gdb to go into an - infinite loop filling up its malloc'd memory. - - main.c (return_to_top_level): Cleanup: call bpstat_clear_actions, - not clear_breakpoints_commands, which is now gone. - (main): If command_loop returns (e.g. from EOF on stdin), do - a quit_command (looping back to command_loop if quit_command - doesn't really quit). - (command_loop): check result from command_line_input and - exit if it returns NULL, rather than passing the NULL to - execute_command. - (gdb_readline): Free malloc'd result space before returning - NULL for EOF. - - * utils.c (query): Handle C-d to mean "yes", just as if the - input was not a terminal.

Rearrange reference-printing - code so it prints: - @0xaddr: value (print w/addressprint) - value (print w/~addressprint) - @0xaddr (parameter lists w/addressprint) - or nothing (parameter lists w/o addressprint) - -Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint) - - * Merge more changes from Per Bothner: - -Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise -annoying) that I tried to improve it. 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. Karl Berry reported the bug. - * source.c - fix openp to avoid //'s in filenames, which - trigger an Emacs bug causing it to not be able to find files - when running gdb in a window. - * dbxread.c - zap the #if 0 that botches the add-file code. - It seems to work a lot better without all the code commented out. - -Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com) - - * Merge Tiemann's and Ted Goldstein's changes, detailed below, - into gdb-3.90.9. - -Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem) - - * Makefile - added a ${CFLAGS} to a couple of entries, - added remote-sa.sparc.c - * added remote.sa-sparc.c, a modification of remote.c - which conducts a dialog directly with the SparcStation prom. - * breakpoint.c, infrun.c, sparcdep.c added - remote_insert_breakpoint(), and remote_remove_breakpoint() - to breakpoint.c instead of directly writing breakpoint instructions. - * sparcdep.c on remote_debugging,there is no need - to remove signle step breakpoint instructions. - * main.c added "-epoch" flag and "int epoch_interface" to main.c - global variable - * printcmd.c - epoch interface sends lisp expressions to open up - epoch windows on inspection. - * valprint.c - added arrayprint, and addressprint and made adding - format controls easier - * wait.h added a couple of undef's because we were getting - complaints about WSTOPSIG and WTERMSIG begin redefined. - - -Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham) - - * symtab.c (decode_line_1): Add support for handling method stubs - in the type information. - -Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham) - - * values.c (baseclass_addr): Run loop from INDEX+1 to - N_BASECLASSES; otherwise, we can still get into a loop. - @@ This should be restructured to use a cleaner search strategy. - -Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham) - - * dbxread.c (define_symbol,read_type): Grok GNU C++'s new - abbreviation "Tt" for tags which have the same name as their - typedecls. - -Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham) - - * symtab.c (list_symbols): add ability to set breakpoints on all - the functions which match a particular regular expression. - -Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham) - - * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we - should print ANSI qualifiers (such as `const' and `volatile'). - All callers changed to call with ANSI == 1, except from - `check_method_stub', which uses old-style syntax. - - * symseg.h (struct fn_field): Remove unneccessary `args' field. - * symtab.h (TYPE_FN_FIELD_ARGS): Redefined. - - * values.c (check_stub_method): New function. - - * cplus-dem.c (do_type): Handle "long long" (encoded as 'x'). - - * dbxread.c (read_type): Handle new GNU C++ method type stubs. - * valprint (type_print_base): Ditto. - - * symtab.c (gdb_mangle_typename): New function. - -Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla) - - * breakpoint.c (catch_command): New function.
