Raw Blame History

Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com)
* coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux,
bfd_coff_swap_lineno): Export the routines that byte-swap COFF
symbol tables if necessary when reading them in, so gdb can use
them. Add "bfd_coff_" to the names so they won't conflict with
names in calling programs. FIXME-soon: if coff-code.h is
included in two BFD modules, this will cause duplicate
definitions; the routines should be exported to a separate,
common, module (probably along with a mess of other ones).
Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com)
Improve modtime support.
* bfd.h: Add boolean mtime_set, and declare bfd_get_mtime.
Remove #define for bfd_get_mtime. Remove gratuitous comment.
* bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached.
BUG: archive members still do not get correct mod times.
Improve floating point support for core files.
* sunos.c (struct core): Change void *fpa_dummy to double fp_stuff.
(sunos4_core_file_p): Create a second registers section in the
core file, called ".reg2", for the float registers.
Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
* many changes to improve archive handling; found a logic flaw in
bfd_check_format which only just happened to work by cooncidence.
Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* bfd.c (bfd_perform_relocation): fixed to use output_offsets
correctly.
* bfd.h: changed type of udata in asymbol to void *, like it
should be. Added bfd_reloc_dangerous enum member.
* coff-code.h: Fixed it so that internally generated symbols get
their values relocated correctly in all cases. Removed calls to
xmalloc.
* icoff.c: Not understanding the destination symbol of a reloc is
not a failure any more, just 'dangerous'. This allows linking of
b.out and coff images.
* sunos.c: Cleaned up the way that ZMAGIC section sizes are
calculated.
Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* sunos.c (translate_to_native_sym_flags): fixed
sym_pointer->n_value so that symbols on the way out get their
section relative values calculated correctly.
* coff-code.h (mangle_symbols): fixed problem where tags were not
being relocated for structs, enums, unions. Also various lints.
Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
* archive.c (get_elt_at_filepos): system_call_error returned
incorrectly.
Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com)
* Resolve the use of no_error and system_call_error.
The bfd library itself now will never set bfd_error to
no_error.
The code still needs to be combed to make sure all the error
codes are correct. I suspect they are not always set correctly.
* The names of all the messages have _ prepended because the sun
bundled compiler can't distinguish from a macro which takes an
argument and the same identifier in a non-macro context.
* The reason for the above being that entry points which used to
be trampoline functions are now just macros which expand to a
direct call through the bfd's xfer vector.
* (../include/intel-coff.h) F_AR32WR: fix this constant. Why
must gas have its own version of everything (the gas version
had the correct value)
Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com)
* b.out.c: Added patches supplied by chrisb@mipon2.intel.com to
properly support i960 architecture and output correct reloc stuff.
* bfd.h: added prototype for bfd_printable_arch_mach, added
BFD_FAIL
* coff-code.h: Applied patches from chrisb to support i960
architecture, zero relocs and swap them correcly and conditionally
compiled the timestamp.
* sunos.c: Made the default section alignment 2^3 so that doubles
are done properly. Fixed the same reloc bug that was in b.out.c
* sysdep.h: Now compiles on a Posix box
Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com)
* icoff.c: Fix comment on big-endian version.
* coff-code.h: Make HAS_RELOC really work (it's backwards from
F_RELFLG). Set F_AR32WR in output files if little endian
architecture.
Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com
* archures.c fixed =/== typo
* sunos.c added architecture stuff for output. Fixed
bug where files where vma(data) != size(text)
were processed wrong.
* coff-code.h added a lint cast
* (../include/a.out.sun4.h) fixed it so zmagic
worked
Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com
* archive.c removed loads of includes, and fixed bug where string
table didn't have a null at the end.
* bfd.c fixed includes, added symbols argument to
canonicalize_reloc entry point.
* libbfd.c fixed includes and added some lint patches.
* targets.c added both sorts of intel coff.
* b.out.c fixed included, changed was the canonical
relocs were done.
* icoff.c added support for callj and big and little
enidian tables.
* opncls.c added chmod+xing for files with EXEC_P set.
* sunos.c fixed includes. Changed default section
alignement to words. Fixed relocation stuff to work with
new scheme
* bfd.h various new types added, prototype for new
reloc calls, changed bfd->iostream to a void *
to including files don't need stdio.h.
* libcoff.h added conversion table to tie relocs to
canonical symbols
* sysdep.h created
* coff-code.h fixed includes. Added code to support
big and little endian formats. Various lints. Better
processing of symbols. Changed reloc stuff to new
order
* libbfd.h fixed includes
Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com
* bfd.h changed name of alignment entry in sec_struct to
alignment_power, because of conflicting uses within bfd.
Now it should be obvious that it's a 2**n alignment
specifier. Removed start_pad, end_alignment, block, minsize,
output_file_alignment, subsection_alignment and original_vma fields.
Added align_power() macro. Fixed bfd_section_alignment
acessor macros. Added bfd_symbol_same_target macro.
* b.out.c (b_out_write_object_contents) fixed to use
new alignment member. Fixed (callj_callback) to use section
relative symbols properly.
* sunos.c (sunos4_object_p) fixed to use new alignment_power.
Fixed (translate_from_native_sym_flags) to correctly make
symbols section relative.
* bfd.c (bfd_errmsg) fixed various enum cast problems.
(bfd_make_section) took out initialization of obsolete members.
(bfd_print_symbol_vandf) added
* opncls.c (bfd_create) created.
* coff-code.h (coff_new_section_hook) took away refs
to obsolete members. (make_a_section_from_file) added
conversion between alignment types. (coff_symbol_from)
added. (coff_count_linenumbers) only counts linenumbers
if symbol is of coff-type. (coff_mangle_symbols) only
heavily mangles symbols if symbol is coff-type.
(coff_write_symbols) various lints. (coff_write_object_contents)
various lints and modification for alignment conversion.
(coff_slurp_relocs) fixed for use with new asection shape.
Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com
* archive.c lots of lint
* b.out.c added callj relocation support, upgrated reloc howto.
Fixed so that asymbol and reloc records are output
correctly.
* bfd.c lots of lint, support for new bfd entry point
bfd_print_symbol.
* bfd.h changed definition of asymbol to contain pointer to
owning bfd, removed target dependencies.
* cache.c took out print statements, put in BFD_ASSERT calls.
* coff-code.h various lints, corrected linenumber output
functionality. Added support for new style asymbols and
bfd_print_symbol. Fixed so that asymbol and
reloc records are handled correctly. Added timestamp.
* icoff.c Added support for new howto shape.
* liba.out.h Added support for new asymbol shape
* libbfd.c various lints
* libbfd.h various lints

and bfd_print_symbol.
Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com
* b.out.c removed prototype of sunos4_ennativate_symtab, lots of
pointer lint. Added support for callj relocation. Fixed bug where
the last 32 bytes of the text section were overwritten by data. Fixed bug
where archives of b.out didn't work due bfd_slurp_extended_name_table
returning false.
* sunos.c added support for n_other field. Braced the howto table so
that it won't be affected by any lengthing of the howto struct typedef.
Various lints
* bfd.h added support for n_other field, added special_function
reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x
macros.
* bfd.c upgraded bfd_perform_relocation, various lints.
Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl)
* ChangeLog: Started ChangeLog for BFD.
* ToDo: Create file for suggestions.
* Makefile: Support easy loading into Saber C.
Add dependencies for icoff.o and bcs88kcoff.o.
Rename coff.c to coff-code.h. Change callers.
* bfd.c (bfd_check_format): Allow the check_format routines
to return the desired target vector, rather than just a Boolean.
bfd.h (bfd_check_format): Change function pointer return type.
archive.c (bfd_generic_archive_p): change callee.
b.out.c (b_out_little_object_p, b_out_big_object_p,
b_out_real_object_p): change callee.
libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false
in check_format transfer vectors that need a filler.
libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls.
bcs88kcoff.c: change callee.
coff-code.h (coff_real_object_p, coff_big_object_p): change callee.
icoff.c: change callee.
sunos.c (sunos4_object_p, sunos4_core_file_p): change callee.
* libbfd.c (zalloc): It should actually zero the storage!
This was commented out for some reason.
* libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls.
This is so callers can avoid <stdlib.h> which doesn't exist
on older systems.
* bfd.c (map_over_sections): Add debugging code, since I
noticed the section count for sunos core files was bad, but only
GDB had detected the problem.
(bfd_set_section_lineno_size, bfd_set_section_linenos,
bfd_get_section_linenos): Remove obsolete functions.
(bfd_apply_relocations): Use longs, not ints, for the math.
* bfd.h: Declare enum boolean and struct bfd_target as well
as typedefs for them. Remove obsolete
bfd_get_section_lineno_size.
* cache.c: Make the "fdopen" support work. Keep better track
of how many files are open. Centralize the opening of files
and be sure bfd_open[rw] actually try to open the file. Evade
linked list initialization problems.
* b.out.c, coff-code.h, opncls.c, sunos.c: lint.
* coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names.
* cplus-dem.c: Delete file, since it is not part of BFD.
* opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
(bfd_openr, bfd_openw): Actually open the file, give error now.
* sunos.c (sunos4_core_file_p): Set section count.
(sunos4_set_section_linenos, stab_names, fprint_name): Eliminiate
obsolete definitions.
(_write_symbol_table): Initialize <idx> counter.
(foop): Eliminate debugging code.
