323 * expr.c: Add "const" modifier to hex_value.
324 * symbols.c: Finish conversion to S_* macros in the VMS only
325 parts of the program. Add "const" modifier to
326 md_[long,short]_jump_size. Remove declaration of const_flag
327 (which will be declared in obj-vms.h).
328 * write.c: Add "const" modifier to md_[long,short]_jump_size.
329 Fix arguments to VMS_write_object_file.
330 * config-gas.com: New file. Script for VMS systems to set up the

347 * obj-vms.c (VMS_write_object_file): Define all vtable psects
348 as symbols as well in the object file. Look for external functions

390 mapping to segT enum values.
391 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
392 if these are used or defined, if BFD_ASSEMBLER.
393 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
394 subseg_new split into two functions.
395 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
397 * as.h (volatile): Don't define if already defined.
398 (had_errors, had_warnings): Provide prototypes for ANSI C even if
400 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,

405 * app.c, config/tc-*.c: Don't include read.h, since it is already
408 * These are based on patches from Minh Tran-le
409 <mtranle@paris.intellicorp.com>.
410 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use

433 (size_section): Restored sanity check.
434 (do_relocs_for): Base section address on s_paddr rather than
435 computing it. Adjust a29k R_IHIHALF special case to account for
436 section paddr (used to require paddr to be zero). If there are no
437 reclos, set s_relptr to 0. Set relocation size in object_headers.
438 (fill_section): Always set s_vaddr here, removing
439 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set

447 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
448 set s_vaddr here. If string_byte_count remains 4, set it back to
449 0, and only write strings out if there are some. Call
450 fill_section before do_relocs_for and do_linenos_for.
451 (obj_coff_section): Handle optional quoted second argument giving
452 section characteristics.
453 (obj_coff_bss): Added to handle .bss.
454 (obj_coff_ident): Added to handle .ident (puts string in .comment

513 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
514 (obj_coff_endef): Don't merge labels or symbols awaiting forward
515 definitions, and don't merge tags with non-tags. Check for .bf
516 rather than just checking whether the second character is b and
517 the third character is f.
518 (obj_coff_val): gcc can generate values which we don't handle
519 correctly; discard information for now, since it only affects the
520 debugging information.

522 (yank_symbols): Don't merge labels.
523 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

526 (obj_coff_section): Accept and ignore a trailing quoted string, as
527 used in AT&T i386 syntax.
528 (fixup_segment): Take segment as argument. On the i386, adjust PC
529 relative addends by the segment vaddr.

661 * all files: Whitespace changes for GNU indentation style, done by
662 GNU `indent'. Some cleanup still needed, especially of comments.
664 * configure.in: No te-386bsd.h file exists; don't try to use it.
666 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
668 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
669 could be doing emulation.
671 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
674 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

700 comment_chars, line_comment_chars and line_seperator_chars
701 consistently const, and always initialized them. Included read.h.
703 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)

735 printed rep of null character.
737 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
739 * obj-coffbfd.c (write_object_file): check return value of
742 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
744 * Support for i386-sysv.
745 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

764 fix i960+non-bfd coff bit rot.
765 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
766 support for C source listings. (obj_coff_endef): look in the right
767 part of the symbol for the symbol name
769 * tc-m68k.c (get_num): make it work for all segments, not just the

783 * tc-z8k.c: lots of bug fixes
785 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
787 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
788 #elif, since it is not supported by old compilers.
789 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
790 couple of expressions in tc-m68k.c.
792 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
794 * read.c (cons): If NO_RELOC is defined, use it.
796 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
798 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
800 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require

815 * listing.c (debugging_pseudo): Add stabs and stabn as things to
818 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
820 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
821 sections starting from zero, rather than making them consecutive.
822 This makes subsequent reloc calculations easier, esp if the object
823 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
824 allocate lcomm in .data rather than in .bss. It seems that some
825 tools can't cope with a non-zero sized bss before linkage.

844 Change LIBDEPS dependence to LIBS.
846 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
848 * Makefile.in (install): if $(tooldir) exists, install as in
851 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
853 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
854 .word is < -32768 or > 32767. The -J flag causes the error to be
855 ignored. This is to catch over-sized switches generated by gcc on
856 systems which don't support the broken .word hack.
857 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
858 write.c (fixup_segment): check for signed .word overflow if
859 WARN_SIGNED_OVERFLOW_WORD.
861 * write.c (fixup_segment): fixed missing parens in expression
862 checking for byte or word overflow.

878 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
880 * input-scrub.c (input_scrub_push): call input_file_begin, not
882 messages.c (as_perror): print ": " between the passed in error and
883 the strerror, like perror does.
885 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
887 * Makefile.in: use gas_target instead of modifying target_cpu.
888 From Steve Chamberlain:
889 Makefile.in: Handle m68*-*-coff*.
890 read.c, read.h: add mult argument to s_space
892 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
893 Motorola and MIT syntax; gas can now assemble either type of

901 (write_object_file) call fixup_mdeps
902 (fixup_segment) set fx_subsy to 0.
903 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
905 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
908 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
910 * Makefile.in (LIBS): Include opcode library.
912 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
914 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
915 including zero are accepted, pass +0.0.

932 tc-i960.c (md_ri_to_chars): Always output bout object file in
933 little endian byte order (used to use endianness of host).
935 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
937 * config/tc-m68k.c (init_table): Now const. Always include 68851
938 data, so that "bc" is available to 68040 cache instructions.
939 Added "tt0", "tt1", and 68ec030 variants.
940 (md_assemble): Complain if 68000 (only) and 68881 are specified.
941 (enum _register): Added TT0, TT1.
942 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
943 line number correctly in "internal error" messages. Don't print
944 architecture-mismatch message for operand errors.
946 From Colin Smith (colin@wrs.com):
947 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
948 than install_operand.
950 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
952 * listing.c (buffer_line): rewind to the start of include
953 files, they might be included twice.
955 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
957 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)

960 one element of a family.
962 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
964 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
965 so that we can assemble hand-written libgcc code.

969 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
970 has already been formatted (but may still contain %-characters).
973 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
975 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
976 written with indirection on the last two operands, which can be
977 either data or address registers. Added a new operand type 'r'
978 which accepts either register type. Added '(' to notend stuff in
979 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
981 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
983 * as.h (enum _relax_state): Start off at one, not zero, to better

992 data_last_frag): No longer static.
993 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
994 defined, call it. Change segments before calling fixup_segment.
995 (relax_align): If linkrelax, provide extra padding.

1228 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
1230 * Makefile.in (install): Install into $(tooldir)/bin, since that's
1231 where gcc looks for it.
1233 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
1235 * Makefile.in: Changed some lines to be less confusing for some

1305 * expr.c (operand): if can't work out what sort of operand it is,
1306 then look through FLT_CHARS for a hint.
1308 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
1310 * Makefile.in, configure.in: removed traces of namesubdir,

1314 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
1315 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1316 copyrights to '92, changed some from Cygnus to FSF.
1318 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1320 * expr.c: If an expression is single comma, then return with
1321 SEG_ABSENT rather than an error - since the sparc front end does
1322 really strange things with things like fbge,a
1324 * as.h: include bfd.h if using many sections
1325 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1326 local labels didn't work.
1327 * listing.c (list_symbol_table): don't core dump when there's no
1329 * write.c, write.h: call fix_new with the right number of args on
1331 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
1334 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1336 * app.c: MRI compatibility - allow single quote to start a string.
1337 * as.c: fix typo recently introduced.
1338 * as.h : Don't include aout/reloc.h - it's not right for COFF!
1339 * expr.c: Much rewriting, to accomodate MRI syntax for
1340 expressions. Also easier to read now.
1341 * listing.c: Put back defuns
1342 * read.c: modified to accept MRI syntax, put back listing pseudo
1343 ops so that an assembler built with NO_LISTING ignores list ops
1345 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1346 machine is a SPARC or a 29K.
1347 * config/obj-aout.c: added s_sect pseudo op
1348 * config/obj-coffbfd.c: lints, set the filehdr flags right and
1349 fill in the timestamp.
1350 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1351 anymore, define all the relocs which the tc-<x> bit will use so we
1352 can translate from them to the coff types.
1353 * config/tc-a29k.c: reloc_type isn't ane enum any more
1354 * config/tc-m68k.c: Added NO_RELOC definition.
1356 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1358 * Makefile.in: put header files before C source for TAGS; remove
1359 references to non-existent syscalls.h.
1361 * read.c, write.c subsegs.c: back out the .bss changes.
1363 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1365 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1369 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
1371 * symbols.c (local_label_name): symbols now start with ^A.
1373 * read.c, subsegs.c, write.c obj-coff.c: added handling of
1374 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1375 generate these sections. .align: will use NOP_OPCODE or 0
1376 for padding. This is just for being nice to the
1379 * expr.c (operand): changed to generate local label "\001L0"
1380 starting with a ^A so that it is recognized as a local label.
1382 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1384 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1385 i/o opcodes - inb, inw, outb and outw. string manipulation with
1386 att syntax - scmp, slod, smov, ssca, ssto.
1388 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1389 to just after .file .
1391 In obj_crawl_symbol_chain() where it tries to put the external
1392 symbols apart, with the condition:
1393 (!S_IS_DEFINED(symbolP) &&
1394 !S_IS_DEBUG(symbolP) &&
1395 !SF_GET_STATICS(symbolP))
1396 it was moving too many symbols out. So I switch it back to the
1398 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1400 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1401 so that we don't use the F_RELFLG which make the linker complain
1402 that somebody has stripped the relocation info.
1404 Also, the AIX ld program require that the relocation table
1405 is sorted by r_vaddr like the standard ATT assembler does.
1407 [he also changed the sizeof(struct ...)'s into the coff
1408 style FOOSZ macros. I'm not sure this is right, but I can't
1409 remember why. xoxorich.]
1411 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
1413 * Makefile.in, configure.in, doc: use the doc. Build it, install

1418 * read.c: white space and comments only.
1420 * configure.in: use the new atof-ns32.c for ns32k.
1422 * write.c: comment change only.
1424 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
1425 aren't yet integrated.
1427 * tc-i860.[hc]: blew off the dust. Something must still be done
1428 about conflicting relocation types.
1430 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1433 * tc-i960.c, tc-sparc.c: white space and comments only.
1435 * tc-a29k.h: delete duplicate macro definition.
1437 * new file atof-ns32k.c copied from hack's last unreleased gas.
1439 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
1441 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1444 * nearly everything. flush ChangeLog, package as gas-1.92.1.
1445 ChangeLog's prior to this are sketchy at best. I have logs.
1446 They just aren't ChangeLogs.
