534 lines; I don't think that can be done portably.
535 * config/tc-mips.c (macro): Use $AT if target register is zero in

610 prototypes for all static functions. Moved existing minimal
611 debugging format support info #ifndef OBJ_ECOFF blocks.
612 (macro_build_lui): Eliminated sign_extend argument, because ECOFF

660 * make-gas.com: Find obstack.obj if it's not in the current
662 * read.c (s_ignore): Don't declare is_end_of_line. It's
663 redundant, and triggers a VMS gcc compiler bug.
665 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
666 current segment as an argument. (Ignored in all cases but VMS.)
667 All callers and definitions changed.

990 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
991 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.

996 * expr.c: Add "const" modifier to hex_value.
997 * symbols.c: Finish conversion to S_* macros in the VMS only
998 parts of the program. Add "const" modifier to
999 md_[long,short]_jump_size. Remove declaration of const_flag
1000 (which will be declared in obj-vms.h).
1001 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1002 Fix arguments to VMS_write_object_file.
1003 * config-gas.com: New file. Script for VMS systems to set up the
1004 configuration to build gas for VMS, and create config.status.

1012 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1013 types of malformed stabs. Change parsing algorithm so that we are
1014 more certain of having all of the information that we need on hand.
1015 * obj-vms.c (final_forward_reference): New function, used to help
1016 resolve the data types of as many struct elements as possible

1020 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1021 as symbols as well in the object file. Look for external functions
1022 that start with "__vt.", and turn them into variables, since the
1023 g++ compiler is incapable of doing this.
1024 * tc-vax.c: Add '1' option for backward compatibility with older GCC
1026 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
1027 * input-scrub.c (as_where): Fix bug where as would crash if we did not
1028 have the name of the source file yet.
1029 * config/ho-vms.h: define HO_VMS, not HO_VAX.
1031 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
1033 * read.c (s_data): Always use "data_section", since it'll map to
1034 SEG_DATA or SEG_E1 if needed.
1035 (s_lcomm): Likewise with bss_section.
1036 (s_fill): Use memset, not bzero.
1038 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

1050 * Changes for BFD_ASSEMBLER:
1051 * obj.h (obj_crawl_symbol_chain): Declare only if not
1053 (obj_header_append, obj_pre_write_hook): Ditto.
1054 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
1055 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
1056 (segment_name) If BFD_ASSEMBLER, look up BFD section name;

1060 (big_section, reg_section, pass1_section, diff_section,
1061 absent_section, text_section, data_section, bss_section): If
1062 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
1063 mapping to segT enum values.

1065 if these are used or defined, if BFD_ASSEMBLER.
1066 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
1067 subseg_new split into two functions.
1068 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
1070 * as.h (volatile): Don't define if already defined.
1071 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1073 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1074 declare with format attribute for -Wformat checking.
1076 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
1078 * app.c, config/tc-*.c: Don't include read.h, since it is already
1081 * These are based on patches from Minh Tran-le
1082 <mtranle@paris.intellicorp.com>.
1083 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1084 obj_format coffbfd and gas_target i386coff for target.
1085 (i[34]86-*-isc*): New host (uses sysv).
1086 * config/i386aix.mt: Removed (no longer used).
1087 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
1089 (LDFLAGS): Added, defined as -shlib.
1090 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1091 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1092 (DOT_LABEL_PREFIX): Define.
1093 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1094 name rather than L0\001.

1097 * symbols.c, symbols.h (local_bss_counter): Removed.
1098 * write.c (write_object_file): bss no longer uses

1106 (size_section): Restored sanity check.
1107 (do_relocs_for): Base section address on s_paddr rather than
1108 computing it. Adjust a29k R_IHIHALF special case to account for
1109 section paddr (used to require paddr to be zero). If there are no
1110 reclos, set s_relptr to 0. Set relocation size in object_headers.
1111 (fill_section): Always set s_vaddr here, removing
1112 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
1113 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
1114 Set STYP_INFO for .comment.

1119 (do_linenos_for): Set lineno size in object_headers.
1120 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
1121 set s_vaddr here. If string_byte_count remains 4, set it back to
1122 0, and only write strings out if there are some. Call
1123 fill_section before do_relocs_for and do_linenos_for.
1124 (obj_coff_section): Handle optional quoted second argument giving
1125 section characteristics.
1126 (obj_coff_bss): Added to handle .bss.
1127 (obj_coff_ident): Added to handle .ident (puts string in .comment

1130 (fixup_mdeps): Change to segment. Call frag_wane after
1132 (fixup_segment): Explicitly check S_IS_COMMON before making 386
1133 adjustment (already happened only for common symbols, but this is
1135 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

1147 (do_scrub_next_char): For \", return " not '.
1148 (symbol_chars): Now const.
1150 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
1151 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
1153 * config/obj-coff.h: Don't use #elif.
1155 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
1156 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

1183 using ZERO_BASED_SEGMENTS.
1184 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
1185 never set segment address for SEG_E2 (.bss) and don't write out
1186 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
1187 (obj_coff_endef): Don't merge labels or symbols awaiting forward
1188 definitions, and don't merge tags with non-tags. Check for .bf
1189 rather than just checking whether the second character is b and
1190 the third character is f.
1191 (obj_coff_val): gcc can generate values which we don't handle
1192 correctly; discard information for now, since it only affects the
1193 debugging information.

1195 (yank_symbols): Don't merge labels.
1196 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

1344 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
1347 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

1376 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
1378 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
1379 constant will not fit in an immediate field.
1380 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

1415 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
1417 * Support for i386-sysv.
1418 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

1456 * tc-z8k.c: lots of bug fixes
1458 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
1460 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
1461 #elif, since it is not supported by old compilers.
1462 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
1463 couple of expressions in tc-m68k.c.
1465 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
1467 * read.c (cons): If NO_RELOC is defined, use it.
1469 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
1471 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
1473 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
1474 local labels to start with a .) and set REGISTER_PREFIX to %.
1475 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
1477 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
1479 * messages.c: Comment changes.
1481 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

1491 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
1493 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
1494 sections starting from zero, rather than making them consecutive.
1495 This makes subsequent reloc calculations easier, esp if the object
1496 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
1497 allocate lcomm in .data rather than in .bss. It seems that some
1498 tools can't cope with a non-zero sized bss before linkage.

1502 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
1503 throughout. That enum no longer means what we thought it meant.

1524 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
1526 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
1527 .word is < -32768 or > 32767. The -J flag causes the error to be
1528 ignored. This is to catch over-sized switches generated by gcc on
1529 systems which don't support the broken .word hack.
1530 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
1531 write.c (fixup_segment): check for signed .word overflow if
1532 WARN_SIGNED_OVERFLOW_WORD.

1561 From Steve Chamberlain:
1562 Makefile.in: Handle m68*-*-coff*.
1563 read.c, read.h: add mult argument to s_space
1565 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

1610 * config/tc-m68k.c (init_table): Now const. Always include 68851
1611 data, so that "bc" is available to 68040 cache instructions.
1612 Added "tt0", "tt1", and 68ec030 variants.
1613 (md_assemble): Complain if 68000 (only) and 68881 are specified.
1614 (enum _register): Added TT0, TT1.
1615 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass

1642 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
1643 has already been formatted (but may still contain %-characters).
1646 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
1648 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
1649 written with indirection on the last two operands, which can be
1650 either data or address registers. Added a new operand type 'r'
1651 which accepts either register type. Added '(' to notend stuff in
1652 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

1999 local labels didn't work.
2000 * listing.c (list_symbol_table): don't core dump when there's no
2002 * write.c, write.h: call fix_new with the right number of args on
2004 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2007 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2009 * app.c: MRI compatibility - allow single quote to start a string.
2010 * as.c: fix typo recently introduced.
2011 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2012 * expr.c: Much rewriting, to accomodate MRI syntax for
2013 expressions. Also easier to read now.
2014 * listing.c: Put back defuns
2015 * read.c: modified to accept MRI syntax, put back listing pseudo
2016 ops so that an assembler built with NO_LISTING ignores list ops
2018 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2019 machine is a SPARC or a 29K.
2020 * config/obj-aout.c: added s_sect pseudo op
2021 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2022 fill in the timestamp.
2023 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2024 anymore, define all the relocs which the tc-<x> bit will use so we
2025 can translate from them to the coff types.
2026 * config/tc-a29k.c: reloc_type isn't ane enum any more
2027 * config/tc-m68k.c: Added NO_RELOC definition.

2031 * Makefile.in: put header files before C source for TAGS; remove
2032 references to non-existent syscalls.h.
2034 * read.c, write.c subsegs.c: back out the .bss changes.
2036 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2038 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

2044 * symbols.c (local_label_name): symbols now start with ^A.
2046 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2047 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2048 generate these sections. .align: will use NOP_OPCODE or 0
2049 for padding. This is just for being nice to the
2052 * expr.c (operand): changed to generate local label "\001L0"
2053 starting with a ^A so that it is recognized as a local label.
2055 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2057 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2058 i/o opcodes - inb, inw, outb and outw. string manipulation with
2059 att syntax - scmp, slod, smov, ssca, ssto.
2061 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2062 to just after .file .
2064 In obj_crawl_symbol_chain() where it tries to put the external
2065 symbols apart, with the condition:
2066 (!S_IS_DEFINED(symbolP) &&
2067 !S_IS_DEBUG(symbolP) &&
2068 !SF_GET_STATICS(symbolP))
2069 it was moving too many symbols out. So I switch it back to the
2071 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2073 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2074 so that we don't use the F_RELFLG which make the linker complain
2075 that somebody has stripped the relocation info.
2077 Also, the AIX ld program require that the relocation table
2078 is sorted by r_vaddr like the standard ATT assembler does.
2080 [he also changed the sizeof(struct ...)'s into the coff
2081 style FOOSZ macros. I'm not sure this is right, but I can't
2082 remember why. xoxorich.]
2084 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
2086 * Makefile.in, configure.in, doc: use the doc. Build it, install
2089 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2091 * read.c: white space and comments only.
2093 * configure.in: use the new atof-ns32.c for ns32k.
2095 * write.c: comment change only.
2097 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2098 aren't yet integrated.
2100 * tc-i860.[hc]: blew off the dust. Something must still be done
2101 about conflicting relocation types.
2103 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2106 * tc-i960.c, tc-sparc.c: white space and comments only.
2108 * tc-a29k.h: delete duplicate macro definition.
2110 * new file atof-ns32k.c copied from hack's last unreleased gas.
2112 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
2114 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
2117 * nearly everything. flush ChangeLog, package as gas-1.92.1.
2118 ChangeLog's prior to this are sketchy at best. I have logs.
2119 They just aren't ChangeLogs.
