|
||
|
|
|
||
|
|
* 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
|
||
|
|
|

|
||
|
|
|
||
|
|
* 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.
|
||
|
|
|
||
|
|

|
|
* coff-code.h added a lint cast

||
|
|
worked
|
||
|
|
|
||
|

|
|
table didn't have a null at the end.

|
|
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.

to obsolete members. (make_a_section_from_file) added
|
||
|
|
conversion between alignment types. (coff_symbol_from)
|
||

added. (coff_count_linenumbers) only counts linenumbers

|
||
|
|
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.
|
||
|
|
|
||
|

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.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
