3 * syms.c (bfd_decode_symclass): Return 'A'
4 for symbols that are both absolute and global.
5 * archive.c (bfd_special_undocumented_glue): Return NULL
6 if bfd_ar_hdr_from_filesystem returns NULL.

10 * Makefile.in: added coff-h8300
11 * configure.in: now h8 is a coff target
12 * cpu-h8300.c: fix various disassembly problems
13 * libcoff.h: took out some code which has been #0ed for a long
14 time.
15 * targets.c: added h8 coff
16 * coff-a29k.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c
17 added new macro RTYPE2HOWTO to take a load of #ifdefs out of
18 coffcode.h
19 * coffcode.h: Started to change the way machine dependencies are
20 handled, from the nest of #ifdefs to macros defined in the
21 including coff-<foo>.c

JG
25 * aoutx.h (some_aout_object_p): Set the `executable' bit
26 if the entry point is contained in the text segment, even if the
27 text segment is at location 0.
28
853f0a70
JG
29 * coff-mips.c, coffcode.h: Peter Schauer's patch to kludge in
30 nonstandard MIPS sections (.rdata, .sdata, etc).
31
f8adc62d 32 * aoutx.h, bfd.c, coffcode.h, ieee.c, oasys.c, targets.c: CONST lint.
8c4a1ace
JG
33 * libbfd-in.h, libbfd.h, aoutx.h, coffcode.h, elf.c, libaout.h:
34 Rename ALIGN to BFD_ALIGN to avoid conflict with BSD <sys/param.h>.
1e310759 35 * libbfd.c: Lint.
f39eae7b

36 * host-aout.c, trad-core.c: Fix write_armap prototypes. Lint.

39
40 * stab-syms.c, syms.c: Moved bfd_stab_name() and bfd_stab_names[]
41 from syms.c to new file stab-syms.c. Also, since GNU extended
42 type codes such as N_SETT are no longer in ../include/stab.def,
43 include them manually.
44 * stab-syms.c, aoutx.h: Renamed bfd_stab_name() and
45 bfd_stab_names[] to aout_stab_name() and aout_stab_names[].
46 * libaout.h: Added prototype for aout_stab_name().
47 * Makefile.in: Update Makefile for new stab-syms.[co].

50
51 * libaout.h (WORK_OUT_FILE_POSITIONS): One more try at this
52 rather complicated seeming problem. Eliminate LOGICAL_ versions,
53 just make N_XXX work by excluding the header from the text segment.
54 * aoutx.h: Fix comments to match.
55
56Tue Nov 19 18:49:01 1991 Per Bothner (bothner at cygnus.com)
57
58 * libaout.h (WORK_OUT_FILE_POSITIONS): Use new LOGICAL_TXTADDR,
59 LOGICAL_TXTOFF, LOGICAL_TXTSIZE macros to figure out numbers
60 for the "logical" text segment (i.e. never consider the exec
61 header to be part of the text segment). This change is
62 needed for consistency with various other parts of bfd and ld.
63 * aoutx.h (NAME(aout,soe_aout_object_p)): Fix comment,
64 and move calculation of obj_textsec(abfd)->size to libaout.h.
65 * bfd-in.h: Removed bogus ';'.
66
67 * Makefile.in: Add MINIMIZE flag to select lean
68 or bloated target_vector.
69 * targets.c: Use new MINIMIZE macro, and add trad_core if needed.
70 * newsos3.c: Fixes to ../include/aout64.h remove need
71 for special N_TXTOFF macro, but require N_HEADER_IN_TEXT.
72
73Mon Nov 18 12:00:59 1991 Per Bothner (bothner at cygnus.com)
74
75 * aout-target.h, aoutf1.h, newsos3.c: Make aout-target.h
76 handle both little and big-endian targets, with little
77 the default unless TARGET_IS_BIG_ENDIAN_P is defined.
78 * host-aout.c: Add FIXME note.
79
80Sun Nov 17 13:29:39 1991 Per Bothner (bothner at cygnus.com)
81
82 * targets.c: Make the default target_vector contain
83 just &DEFAULT_VECTOR. This makes executables a lot smaller.
84 Old behavior can be gotten by defining ALL_TARGETS.
85 * aoutf1.h, demo64.c, i386aout.c, newsos3.c, sunos.c:
86 Factored out common code into new file aout-target.h.
87 Saves a lot of duplicate code for a.out variants.
88
89Fri Nov 15 13:00:43 1991 Per Bothner (bothner at cygnus.com)
90
91 Get 'make headers' to work when configured with +subdirs.
92 * Makefile.in: Add $(subdir) to docdir path.
93 * doc/Makefile.in (protos): Add $(srcdir) prefix
94 to name of sed scripts.

99 * syms.c (bfd_stab_names): Turn on new GNU_EXTRA_STABS macro
100 to include names of N_SETT etc.

104 * elf.c: Add minimal support for ELF symbol tables. Generates
105 canonical bfd symbol tables from ELF symbol tables. Change the
106 name of some functions from bfd_<name> to elf_<name>.

108 * syms.c: Trivial fix to comment to remove a redundant "to".

113 form that GDB recognizes as COFF.

129 * coff-m88k.c: create coff armaps instead of bsd ones.
130 * opncls.c (bfd_close_all_done), (bfd_close): Mask out random bits
131 when calling chmod.

133Mon Nov 11 19:07:32 1991 Fred Fish (fnf at cygnus.com)
134
135 * elf.c: Additions to support ELF format core files.
136 * config/mh-amix: Add -DHAVE_PROCFS to HDEFINES, since host
137 has support for /proc (all the include files in particular).

141 * aoutx.h (NAME(aout,find_nearest_line)): Handle the case
142 of two N_SO stabs, one for directory, and one for filename.
143
144 * bfd-in.h (print_vma): Factor out duplicate definition.
145
146 Exit a little more gracefully when malloc returns NULL.
147 * libbfd.c: New function bfd_xmalloc (malloc wrapper).
148 * opncls.c, syms.c, bout.c, aoutx.h: Replace malloc by bfd_xmalloc.
149 * libbfd.h: Rre-generated due to libbfd.c update.

161 core files, when compiling native.
162 * hosts/h-rs6000.h: Define FASCIST_FDOPEN for bfd_fdopenr.
163

165 to the way it was.

167Thu Nov 7 11:03:55 1991 Steve Chamberlain (sac at rtl.cygnus.com)
168
169 * coffcode.h: Defined new macros [PUT|GET]LINENO_LNNO for
170 manipulation of lnno fields in lineno structs in a coff-<f>.h
171 independent way. Override it in coff-<f>.h to your favourite
172 number if you don't have a 16bit lnno field. (coff_swap_lineno_in)
173 (coff_swap_lineno_out): modified to use the new macros.
174
175Mon Nov 4 11:38:33 1991 Steve Chamberlain (sac at cygnus.com)
176
177 * aoutf1.h (sunos4_callback): Now defaults to 68020 rather than
178 unknown arch when the magic number doesn't specify the
179 architecture, since some OSs (eg old sun3s) don't set the number, and
180 020 is probably the right answer anyway.

182Sun Nov 3 12:07:08 1991 Per Bothner (bothner at cygnus.com)
183
184 * hosts/h-news.h, hosts/h-rtbsd.h:
185 Get rid of MISSING_VFPRINTF, since libiberty provides one.
186 * bfd-in.h (bfd_print_symbol_type_hopw enum): Add new option
187 bfd_print_symbol_nm, for use by nm.
188 * aoutx.h (NAME(aout,print_symbol)): Add code for new
189 bfd_print_symbol_nm option, to print in nm format.
190 * coffcode.h (coff_print_symbol), ieee.c (ieee_print_symbol)
191 oasys.c (oasys_print_symbol): Provide stub implementations
192 for bfd_print_symbol_nm.
193 * syms.c: New function bfd_decode_symclass, used by nm printer.
194 New function bfd_stab_name to look up string name of stab code.

197
198 * Makefile.in: Added ctor.c
199 * archures.c (bfd_default_arch_struct) added
200 bfd_default_reloc_type_lookup.
201 * coffcode.h: removed a load of #if 0ed code.
202 (coff_compute_file_section_positions): now works out the section
203 alignment and size correctly in all cases.
285dbe19 204 (coff_get_symtab): looks for constructor symbols and calls the
522e0ead 205 right function when they're found. (coff_canonicalize_reloc):
285dbe19 206 knows when a section is full of constructors and does the right
522e0ead
SC
207 thing.
208 * cpu-m88k.c: Added default_reloc_type lookup to the architecture
209 description.
210 * libbfd-in.h: (bfd_default_reloc_type_lookup) defun added.
211 * libcoff.h: removed #if 0ed code

285dbe19 213 arch independent constructor relocation type.
522e0ead
SC
214 (bfd_reloc_type_lookup): removed the comment "this will go away"
215 since it won't. (bfd_howto_32): stolen from 88k, this is a 32bit
216 reloc which is used when BFD_RELOC_CTOR falls through to give a
285dbe19 217 default 32bit reloc for constructors.
522e0ead
SC
218 (bfd_default_reloc_type_lookup): added.
