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

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

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

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

438 (size_section): Restored sanity check.
439 (do_relocs_for): Base section address on s_paddr rather than
440 computing it. Adjust a29k R_IHIHALF special case to account for

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

520 definitions, and don't merge tags with non-tags. Check for .bf
521 rather than just checking whether the second character is b and
522 the third character is f.
523 (obj_coff_val): gcc can generate values which we don't handle
524 correctly; discard information for now, since it only affects the
525 debugging information.

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

666 * all files: Whitespace changes for GNU indentation style, done by
667 GNU `indent'. Some cleanup still needed, especially of comments.
669 * configure.in: No te-386bsd.h file exists; don't try to use it.
671 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
673 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
674 could be doing emulation.

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

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

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

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

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

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

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

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

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

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

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

1181 * write.c (write_object_file): keep the fix_tail clean, which
1182 fixes a bug in -R where relocations were being lost.

1233 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
1235 * Makefile.in (install): Install into $(tooldir)/bin, since that's
1236 where gcc looks for it.
1238 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
1240 * Makefile.in: Changed some lines to be less confusing for some

1310 * expr.c (operand): if can't work out what sort of operand it is,
1311 then look through FLT_CHARS for a hint.
1313 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
1315 * Makefile.in, configure.in: removed traces of namesubdir,

1319 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
1320 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1321 copyrights to '92, changed some from Cygnus to FSF.
1323 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1325 * expr.c: If an expression is single comma, then return with
1326 SEG_ABSENT rather than an error - since the sparc front end does
1327 really strange things with things like fbge,a
1329 * as.h: include bfd.h if using many sections
1330 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1331 local labels didn't work.
1332 * listing.c (list_symbol_table): don't core dump when there's no
1334 * write.c, write.h: call fix_new with the right number of args on
1336 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
1339 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1341 * app.c: MRI compatibility - allow single quote to start a string.
1342 * as.c: fix typo recently introduced.
1343 * as.h : Don't include aout/reloc.h - it's not right for COFF!
1344 * expr.c: Much rewriting, to accomodate MRI syntax for
1345 expressions. Also easier to read now.
1346 * listing.c: Put back defuns
1347 * read.c: modified to accept MRI syntax, put back listing pseudo
1348 ops so that an assembler built with NO_LISTING ignores list ops
1350 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1351 machine is a SPARC or a 29K.
1352 * config/obj-aout.c: added s_sect pseudo op
1353 * config/obj-coffbfd.c: lints, set the filehdr flags right and
1354 fill in the timestamp.
1355 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1356 anymore, define all the relocs which the tc-<x> bit will use so we
1357 can translate from them to the coff types.
1358 * config/tc-a29k.c: reloc_type isn't ane enum any more
1359 * config/tc-m68k.c: Added NO_RELOC definition.
1361 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1363 * Makefile.in: put header files before C source for TAGS; remove
1364 references to non-existent syscalls.h.
1366 * read.c, write.c subsegs.c: back out the .bss changes.
1368 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1370 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1374 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
1376 * symbols.c (local_label_name): symbols now start with ^A.
1378 * read.c, subsegs.c, write.c obj-coff.c: added handling of
1379 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1380 generate these sections. .align: will use NOP_OPCODE or 0
1381 for padding. This is just for being nice to the
1384 * expr.c (operand): changed to generate local label "\001L0"
1385 starting with a ^A so that it is recognized as a local label.
1387 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1389 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1390 i/o opcodes - inb, inw, outb and outw. string manipulation with
1391 att syntax - scmp, slod, smov, ssca, ssto.
1393 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1394 to just after .file .
1396 In obj_crawl_symbol_chain() where it tries to put the external
1397 symbols apart, with the condition:
1398 (!S_IS_DEFINED(symbolP) &&
1399 !S_IS_DEBUG(symbolP) &&
1400 !SF_GET_STATICS(symbolP))
1401 it was moving too many symbols out. So I switch it back to the
1403 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1405 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1406 so that we don't use the F_RELFLG which make the linker complain
1407 that somebody has stripped the relocation info.
1409 Also, the AIX ld program require that the relocation table
1410 is sorted by r_vaddr like the standard ATT assembler does.
1412 [he also changed the sizeof(struct ...)'s into the coff
1413 style FOOSZ macros. I'm not sure this is right, but I can't
1414 remember why. xoxorich.]
1416 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
1418 * Makefile.in, configure.in, doc: use the doc. Build it, install

1423 * read.c: white space and comments only.
1425 * configure.in: use the new atof-ns32.c for ns32k.
1427 * write.c: comment change only.
1429 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
1430 aren't yet integrated.
1432 * tc-i860.[hc]: blew off the dust. Something must still be done
1433 about conflicting relocation types.
1435 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1438 * tc-i960.c, tc-sparc.c: white space and comments only.
1440 * tc-a29k.h: delete duplicate macro definition.
1442 * new file atof-ns32k.c copied from hack's last unreleased gas.
1444 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
1446 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1449 * nearly everything. flush ChangeLog, package as gas-1.92.1.
1450 ChangeLog's prior to this are sketchy at best. I have logs.
1451 They just aren't ChangeLogs.
