symbol table and add symbol information to the misc function vector. This allows minimum functionality with non -g compiled code, and is vital for use with shared libraries (non of which are currently compiled with -g). Note to anyone doing any SVR4/gdb work. This bug was introduced into gdb just prior to the gdb 4.4 release, thus any versions currently in the field will have broken shared library support since no symbol information at all will be available for the shared library. This fix, along with one about to go into bfd's elf.c should fix that problem.

<mccanne@horse.ee.lbl.gov>.
|

Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
|
||
|
||
* mipsread.c (parse_partial_symbols): Handle dependencies
|
||
between partial symbol tables (when not doing stabs-in-ecoff).
|
||
(This used to be handled by parse_fdr, but parse_fdr was
|
||
incompatible with handling stabs-in-ecoff, so the code
|
||
was re-written to not use parse_fdr. Unfortunately,
|
||
the logic to handle dependencies was overlooked.)
|
||
|
||
Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
|
||
|
||
* coffread.c (read_enum_type): Use the size of a target int when
|
||
describing enum.
|
||
* defs.h: added new #define for TARGET_PTR_BIT, defaults to size
|
||
of target int.
|
||
* h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
|
||
* symtab.c (lookup_reference_type, lookup_ptr_type): use
|
||
TARGET_PTR_BIT to determine size of a pointer
|
||
* values.c (unpack_long): when unpacking a REF or a PTR don't
|
||
assume the size of the type.
|
||
|
||
Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
|
||
|
||
* mipsread.c (parse_symbol): Avoid clobbering enum pointer when
|
||
looking at its members. Improve guess between struct and union,
|
||
only assuming union if multiple members have offsets of zero.
|
||
|
||
Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
|
||
|
||
* mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
|
||
(This is just for clarity - and one day permitting us to
|
||
change FP0_REGNUM from 38 to 32, which would make more sense.)
|
||
* tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
|
||
register numbers in stabs-in-ecoff get handled correctly.
|
||
|
||
Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
|
||
config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
|
||
into BSD and Ultrix.
|
||
|
||
Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
|

* dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
|
||
|
||
Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* Makefile.in: Increment version to 4.4.1.
|
||
* main.c (print_gdb_version): Update copyright notice.
|
||
|
||
Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
|
||
|
||
* mipsread.c: Prepend "struct " to the names of structure
|
||
types, and similarly for enums and unions. (This used
|
||
to be done, but got lost in the re-write to "guess" the
|
||
difference between enum/struct/union.)
|
||
Also, guess that a tag is an enum if the first member
|
||
has type btNil.
|
||
|
||
Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* xm-vax.h: #ifndef ultrix around #include of endian.h and
|
||
limits.h (sigh).
|
||
|
||
Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
|
||
|
||
* Projects: Patching executables is done.
|
||
* Makefile.in (VERSION): Roll to gdb-4.4.
|
||
* README, WHATS.NEW: Update for gdb-4.4.
|
||
|
||
* symfile.c (reread_symbols): Whenever we reread one object
|
||
file's symbols, we must restart the scan, because the object_files
|
||
chain has been permuted.
|
||
|
||
* exec.c (exec_files_info): Split out into print_section_info.
|
||
Print BFD filename of each section if it's not the default one.
|
||
* core.c (core_files_info): Call print_section_info.
|
||
|
||
* xm-vax.h: Include a few system header files whose definitions
|
||
must precede defs.h.
|
||
* language.c, language.h: Make some things const.
|
||
* expression.h, main.c: const spreads like ooze.
|
||
|
||
* mem-break.c (break_insn, break_insn_size): Use unsigned chars,
|
||
since BREAKPOINT values can be >0x80.
|
||
|
||
Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* infrun.c, xm-i386sco.h: SCO needs to use setpgid().
|
||
|
||
Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
|
||
|
||
* sparc-pinsn.c: Remove kludge for preferring architectures.
|
||
Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
|
||
and forever. Add `add' instruction to the set that get checked
|
||
for a preceding `sethi' in order to print an absolute address.
|
||
Corresponding changes in ../include/opcode/sparc.h needed
|
||
to eliminate garbage instructions.
|
||
|
||
Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
|
||
|
||
* mipsread.c (parse_partial_symbols): Make sure partial
|
||
symbols are created for external symbols (as used to be
|
||
the case). This is a bit of a pain with the mips-coff.
|
||
It uses a table which points to all of the external
|
||
symbols belonging to a particular FDR or psymtab.
|
||
Once we've generated this table, we might as well save
|
||
it, and then use it in psymtab_to_symtab_1 to find
|
||
the symbols to pass to parse_external().
|
||
* symfile.c, symfile.c: New function start_psymtab_common
|
||
to share the common parts of allocating a new psymtab
|
||
for dbxread, mipsread (and later dwarfread). Its code
|
||
was pulled out from start_psymtab in dbxread.c.
|
||
* dbxread.c (start_psymtab): Use start_psymtab_common().
|
||
|
||
* valprint.c (val_print): If there is an error when trying
|
||
to print a string, check to see if there really is a problem
|
||
by reading just one character. If that works, assume
|
||
things are ok.
|
||
|
||
Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
|
||
cypress, v8 mnemonics in that order.
|
||
|
||
Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
|
||
|
||
* sparc-pinsn.c: Put the qsort() back in.
|
||
|
||
Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
|
||
|
||
* findvar.c (read_register, write_register): Handle machines
|
||
where REGISTER_TYPE is not the same size as "int".
|
||
|
||
Handle debug symbols in dynamically loaded (relocated) code:
|
||
|
||
* dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
|
||
offset to process_one_symbol.
|
||
(process_one_symbol): Take new offset parameter. Add it into
|
||
appropriate symbol types to relocate symbols to loaded addresses.
|
||
Handle all possible symbol types, and complain() about types that
|
||
we don't expect to see.
|
||
* mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
|
||
process_one_symbol (FIXME, should pass real offset).
|
||
|
||
Misc bugfixes:
|
||
|
||
* breakpoint.c (resolve_sal_pc): Split out code to resolve a
|
||
sal's PC value.
|
||
(set_breakpoint, break_command_1, until_break_command,
|
||
catch_command_1, breakpoint_re_set_one): Use it.
|
||
* symtab.h (resolve_sal_pc): Declare.
|
||
* infcmd.c (jump_command): Use resolve_sal_pc.
|
||
|
||
* source.c (list_command): Shorten "FILE, line N" to "FILE:N".
|
||
|
||
* putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
|
||
|
||
* c-exp.y (yylex): `this' and `template' are only tokens in C++.
|
||
|
||
* xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
|
||
xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
|
||
Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
|
||
|
||
Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* dbxread.c (process_one_symbol): Make a first cut at handling
|
||
symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
|
||
|
||
* symtab.c (find_pc_line): Fix stepping into and out of #included
|
||
files.
|
||
|
||
Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
|
||
no longer any need to copy ../include/opcode/* into gdb.
|
||
|
||
Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)

|
||
|
||
* valprint.c (type_print_base, type_print_method_args):
|
||
Print C++ constructor methods without bogus "return type."
|
||
|
||
Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||
* infptrace.c (child_xfer_memory): Parameter "target" should
|
||
be a pointer to a structure, not the entire structure.
|
||
|
||
Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||
* depend: Convert the couple of references to ansidecl.h that
|
||
used the local gdb version to use the ../include version.
|
||
|
||
Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||
* procfs.c
|
||
(child_xfer_memory): Takes pointer to a struct, not entire struct.
|
||
(inferior_proc_init): Fix non-ANSI version of args.
|
||
(attach): Call print_sys_errmsg with correct number of args.
|
||
(mappingflags): Make static, does not need to be global.
|
||
|
||
* i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
|
||
not the entire struct itself.
|
||
|
||
* valops.c (value_assign): Cast some args to modify_field() and
|
||
{read,write}_register_bytes() correctly.
|
||
|
||
* ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
|
||
|
||
* Makefile.in (MALLOCSRC): Removed reference to removed local
|
||
copy of ansidecl.h.
|
||
|
||
* dwarfread.c (list_in_scope): Needs an initial value, use file
|
||
scope.
|
||
|
||
Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
|
||
|

|
||
|
||
* cplus-dem.c (cplus_demangle): Correctly demangle destructors.
|
||
|
||
Sat Jan 18 17:17:45 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* Makefile.in (HFILES): Add partial-stab.h.
|
||
|
||
Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||
* config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
|
||
New files for stratus. Not complete enough to actually build
|
||
on the Stratus machine; that awaits copyright assignment for
|
||
i860 changes.
|
||
|
||
* Makefile.in (USER_CFLAGS): Add macro specifically reserved
|
||
for getting custom flags into CFLAGS when doing makes.
|
||
|
||
* configure.in: Add config information for stratus.
|
||
|
||
Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dbxread.c (process_one_symbol): Pass address of structure
|
||
to complain(), rather than the whole structure.
|
||
|
||
Wed Jan 15 09:56:16 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||
* solib.c (solib_add_common_symbols): Only compile in when not
|
||
using SVR4 style shared libraries.
|
||
|
||
Tue Jan 14 22:34:00 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||

|
||
values that are computed off a base register.
|
||
|
||
* dwarfread.c (new_symbol): Rework TAG_global_variable and
|
||
TAG_local_variable cases to account for static variables

||
Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
|

|
||
doesn't exist on some systems.
|
||
|
||
* infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
|
||
nexting over recursive function calls.
|
||
|
||
* target.c (target_read_string): Create this routine to read null
|
||
terminated strings from the target. It deals with running off the
|
||
end of memory elegantly as well. solib.c (find_solib): Use
|
||
target_read_string() to avoid problems with running off the end of
|
||
memory.
|
||
|
||
* inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
|
||
that reference pgrp_inferior.
|
||
|
||
Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)
|
||
|
||
* tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that

||
mips-tfile has been hacked to act more "traditionally."
|
||
* dbxread.c: Fixed typo in comment.
|
||
|
||
Sun Jan 12 13:08:36 1992 Per Bothner (bothner at cygnus.com)
|
||
|
||
* mips-tdep.c (mips_skip_prologue): Add some number of
|
||
'sw' instructions before 'addiu' adjusts the stack.
|
||
|
||
Fri Jan 10 13:47:06 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||
* dwarfread.c (start_symtab, end_symtab, scopecount, openscope,

||
freescope, buildblock closescope, record_line, add_symbol_to_list,
|
||
gatherblocks, make_blockvector): Extensive changes to switch
|

to generic symbol table building code in buildsym.c. Remove
|
||
scope tree structures and functions, symbol table building
|
||
functions, and lots of other small changes.
|
||
|
||
* dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove
|
||
GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.
|

Tue Jan 7 13:09:57 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* buildsym.c (cleanup_undefined_types): Add support for enums.
|

|
||
bad type' problem.

||
|
||
Sun Jan 5 09:47:50 1992 Stu Grossman (grossman at cygnus.com)
|
||
|
||
* dbxread.c: detect gcc2 compilations.
|
||
|
||
Thu Jan 2 15:07:41 1992 John Gilmore (gnu at cygnus.com)
|
||
|
||
* sparc-pinsn.c: Rename bitfields that overlap with macro names
|
||
in ../include/opcode/sparc.h.
|
||
|
||
Wed Jan 1 04:29:00 1992 Fred Fish (fnf at cygnus.com)
|
||
|
||
* Makefile.in: Change tm-svr4.h to tm-sysv4.h. Change xm-svr4.h
|
||
to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
|
||
to reflect actual locations of opcode files, so TAGS target will
|
||
be buildable.
|
||
|
||
* i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
|
||
|
||
* i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
|
||
code.
|
||
|
||
