Tue Oct 20 13:02:25 1992 Ian Lance Taylor (ian@cygnus.com)
* Support for i386-sysv.
obj-coffbfd.c (do_relocs_for, write_object_file): set segment
addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
be used to set them all to zero as was done before.
(fill_section): segment addresses now set in write_object_file.
(fill_section): Don't set STYP_NOLOAD for .bss section.
(fixup_segment): 386 uses strange common symbol format.
tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
compatibility with SVR3.2 linker.
Mon Oct 5 09:28:57 1992 Steve Chamberlain (sac@thepub.cygnus.com)
fix i960+non-bfd coff bit rot.
* obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
support for C source listings. (obj_coff_endef): look in the right
part of the symbol for the symbol name
* tc-m68k.c (get_num): make it work for all segments, not just the
first three.
Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* obj-coffbfd.c (write_object_file): don't fixup for the z8k
* tc-z8k.c: lots of bug fixes
Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
* tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
#elif, since it is not supported by old compilers.
ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
couple of expressions in tc-m68k.c.
Mon Sep 28 21:16:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
* tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
* tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
local labels to start with a .) and set REGISTER_PREFIX to %.
tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
* obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
sections starting from zero, rather than making them consecutive.
This makes subsequent reloc calculations easier, esp if the object
format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
allocate lcomm in .data rather than in .bss. It seems that some
tools can't cope with a non-zero sized bss before linkage.
Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
* tc-m68k.c: Replace "enum m68k_architecture" with "int"
throughout. That enum no longer means what we thought it meant.
* tc-m68k.c (md_assemble, md_parse_option): Handle new
"-mno-688[58]1" options.
* tc-m68k.c: Added CPU32 support.
Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* tc-m68k.c (m68k_ip): An(disp) is not pc relative.
Sun Sep 13 20:29:39 1992 Ian Lance Taylor (ian@cygnus.com)
* obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
obj-coffbfd.c (fixup_segment): check for signed .word overflow if
WARN_SIGNED_OVERFLOW_WORD.
* obj-coffbfd.c (fixup_segment): fixed missing parens in
expression checking for byte or word overflow.
Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
Support for i386 coff
* obj-coffbfd.h : added stuff
* tc-i386.c (tc_coff_fix2rtype): new function
* tc-i386.h : new coff defines
Wed Sep 9 11:10:24 1992 Ian Lance Taylor (ian@cygnus.com)
* tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
Motorola and MIT syntax; gas can now assemble either type of
file.
tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
From Steve Chamberlain:
m68kcoff.mt: for m68k COFF.
obj-coffbfd.c: (fixup_mdeps) added
(size_section) removed bad sanity check
(fill_section) added rs_machine_dependent case
(write_object_file) call fixup_mdeps
(fixup_segment) set fx_subsy to 0.
obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
handle m68k.
tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
pseudo ops.
Fri Aug 28 16:25:22 1992 Ian Lance Taylor (ian@cygnus.com)
* obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
tc-i960.c (md_ri_to_chars): Always output bout object file in
little endian byte order (used to use endianness of host).
Tue Aug 25 15:11:08 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* z8k.c, z8k.h, z8k.mt: z8000 support stuff
Mon Aug 24 12:45:12 1992 Ian Lance Taylor (ian@cygnus.com)
* tc-m68k.c: use TARGET_CPU to choose default cpu type.
* te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
so that we can assemble hand-written libgcc code.
Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
* tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
written with indirection on the last two operands, which can be
either data or address registers. Added a new operand type 'r'
which accepts either register type. Added '(' to notend stuff in
tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
Tue Aug 11 12:58:14 1992 Ken Raeburn (raeburn@cygnus.com)
* sparc.mt: New file.
Mon Aug 10 14:37:08 1992 Per Bothner (bothner@cygnus.com)
* tc-m68k.c: ".align N" means align to N-byte boundary *only*
if TN_SUN3; otherwise align to 2**N-byte bounary.
Thu Aug 6 12:08:42 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* config/tc-h8300.c: if a :8 is seen after an operand, fill top
two bytes of any constant with 0xff:
Wed Aug 5 01:54:34 1992 John Gilmore (gnu at cygnus.com)
* tc-m68k.c (try_index): Error if index scaling specified and
assembling for an older CPU than a 68020.
Mon Jul 6 17:09:32 1992 Steve Chamberlain (sac@cygnus.com)
* obj-coffbfd.c (fill_section): mark .lit sections as STYP_LIT
Tue Jun 9 07:50:46 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* tc-m68k.c (m68kip): Fix typo so that only arch's >=68020 do
pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put
it into SEG_BSS
Thu May 28 11:20:27 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
* tc-sparc.c: Use new ARCHITECTURES_CONFLICT_P macro. Mention new
-Asparclite flag.
Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
calc the base of relocs correctly.
* tc-a29k.c (parse_operand): allow expressions to be in any section.
Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
* tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
tc-m68k.h to te-sun3.h.
Wed Mar 11 23:34:46 1992 K. Richard Pixley (rich@cygnus.com)
* te-sun3.h: add LOCAL_LABELS_DOLLAR.
Fri Feb 21 06:22:15 1992 K. Richard Pixley (rich@rtl.cygnus.com)
* obj-aout.c: do not include stab.gnu.h if NO_LISTING.
* tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
* a.out.h: removed.
Fri Feb 21 02:17:22 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
* tc-i386.c: tc-i386.c: added handling of the following opcodes:
i/o opcodes - inb, inw, outb and outw. string manipulation with
att syntax - scmp, slod, smov, ssca, ssto.
Fri Feb 21 01:53:50 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
* obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
to just after .file .
In obj_crawl_symbol_chain() where it tries to put the external
symbols apart, with the condition:
(!S_IS_DEFINED(symbolP) &&
!S_IS_DEBUG(symbolP) &&
!SF_GET_STATICS(symbolP))
it was moving too many symbols out. So I switch it back to the
condition:
(S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
so that we don't use the F_RELFLG which make the linker complain
that somebody has stripped the relocation info.
Also, the AIX ld program require that the relocation table
is sorted by r_vaddr like the standard ATT assembler does.
[he also changed the sizeof(struct ...)'s into the coff
style FOOSZ macros. I'm not sure this is right, but I can't
remember why. xoxorich.]
Tue Feb 18 02:11:10 1992 K. Richard Pixley (rich at cygnus.com)
* tc-m88k.[hc]: pulled in from hack's unfinished work. These
aren't yet integrated.
* tc-i860.[hc]: blew off the dust. Something must still be done
about conflicting relocation types.
* tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
real thing.
* tc-i960.c, tc-sparc.c: white space and comments only.
* tc-a29k.h: delete duplicate macro definition.
* new file atof-ns32k.c copied from hack's last unreleased gas.
