3 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4 sections starting from zero, rather than making them consecutive.
5 This makes subsequent reloc calculations easier, esp if the object
6 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7 allocate lcomm in .data rather than in .bss. It seems that some
8 tools can't cope with a non-zero sized bss before linkage.
10 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
12 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
13 throughout. That enum no longer means what we thought it meant.
15 * tc-m68k.c (md_assemble, md_parse_option): Handle new
16 "-mno-688[58]1" options.
18 * tc-m68k.c: Added CPU32 support.
20 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
22 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
24 Sun Sep 13 20:29:39 1992 Ian Lance Taylor (ian@cygnus.com)
26 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
27 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
28 WARN_SIGNED_OVERFLOW_WORD.
30 * obj-coffbfd.c (fixup_segment): fixed missing parens in
31 expression checking for byte or word overflow.
33 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
36 * obj-coffbfd.h : added stuff
37 * tc-i386.c (tc_coff_fix2rtype): new function
38 * tc-i386.h : new coff defines
40 Wed Sep 9 11:10:24 1992 Ian Lance Taylor (ian@cygnus.com)
42 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
43 Motorola and MIT syntax; gas can now assemble either type of
45 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
46 From Steve Chamberlain:
47 m68kcoff.mt: for m68k COFF.
48 obj-coffbfd.c: (fixup_mdeps) added
49 (size_section) removed bad sanity check
50 (fill_section) added rs_machine_dependent case
51 (write_object_file) call fixup_mdeps
52 (fixup_segment) set fx_subsy to 0.
53 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
55 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
58 Fri Aug 28 16:25:22 1992 Ian Lance Taylor (ian@cygnus.com)
60 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
61 tc-i960.c (md_ri_to_chars): Always output bout object file in
62 little endian byte order (used to use endianness of host).
64 Tue Aug 25 15:11:08 1992 Steve Chamberlain (sac@thepub.cygnus.com)
66 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
68 Mon Aug 24 12:45:12 1992 Ian Lance Taylor (ian@cygnus.com)
70 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
72 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
73 so that we can assemble hand-written libgcc code.
75 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
77 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
78 written with indirection on the last two operands, which can be
79 either data or address registers. Added a new operand type 'r'
80 which accepts either register type. Added '(' to notend stuff in
81 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
83 Tue Aug 11 12:58:14 1992 Ken Raeburn (raeburn@cygnus.com)
87 Mon Aug 10 14:37:08 1992 Per Bothner (bothner@cygnus.com)
89 * tc-m68k.c: ".align N" means align to N-byte boundary *only*
90 if TN_SUN3; otherwise align to 2**N-byte bounary.
92 Thu Aug 6 12:08:42 1992 Steve Chamberlain (sac@thepub.cygnus.com)
94 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
95 two bytes of any constant with 0xff:
97 Wed Aug 5 01:54:34 1992 John Gilmore (gnu at cygnus.com)
99 * tc-m68k.c (try_index): Error if index scaling specified and
100 assembling for an older CPU than a 68020.
102 Mon Jul 6 17:09:32 1992 Steve Chamberlain (sac@cygnus.com)
104 * obj-coffbfd.c (fill_section): mark .lit sections as STYP_LIT
106 Tue Jun 9 07:50:46 1992 Steve Chamberlain (sac@thepub.cygnus.com)
108 * tc-m68k.c (m68kip): Fix typo so that only arch's >=68020 do
109 pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
110 68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
111 the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put
114 Thu May 28 11:20:27 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
116 * tc-sparc.c: Use new ARCHITECTURES_CONFLICT_P macro. Mention new
119 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
121 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
122 calc the base of relocs correctly.
123 * tc-a29k.c (parse_operand): allow expressions to be in any section.
125 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
127 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
128 tc-m68k.h to te-sun3.h.
130 Wed Mar 11 23:34:46 1992 K. Richard Pixley (rich@cygnus.com)
132 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
134 Fri Feb 21 06:22:15 1992 K. Richard Pixley (rich@rtl.cygnus.com)
136 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
138 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
142 Fri Feb 21 02:17:22 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
144 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
145 i/o opcodes - inb, inw, outb and outw. string manipulation with
146 att syntax - scmp, slod, smov, ssca, ssto.
148 Fri Feb 21 01:53:50 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
150 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
151 to just after .file .
153 In obj_crawl_symbol_chain() where it tries to put the external
154 symbols apart, with the condition:
155 (!S_IS_DEFINED(symbolP) &&
156 !S_IS_DEBUG(symbolP) &&
157 !SF_GET_STATICS(symbolP))
158 it was moving too many symbols out. So I switch it back to the
160 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
162 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
163 so that we don't use the F_RELFLG which make the linker complain
164 that somebody has stripped the relocation info.
166 Also, the AIX ld program require that the relocation table
167 is sorted by r_vaddr like the standard ATT assembler does.
169 [he also changed the sizeof(struct ...)'s into the coff
170 style FOOSZ macros. I'm not sure this is right, but I can't
171 remember why. xoxorich.]
173 Tue Feb 18 02:11:10 1992 K. Richard Pixley (rich at cygnus.com)
175 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
176 aren't yet integrated.
178 * tc-i860.[hc]: blew off the dust. Something must still be done
179 about conflicting relocation types.
181 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
184 * tc-i960.c, tc-sparc.c: white space and comments only.
186 * tc-a29k.h: delete duplicate macro definition.
188 * new file atof-ns32k.c copied from hack's last unreleased gas.
