21 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
22 case to set obj_format=elf. Must go before i386-*-sysv* case that
23 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and

51 * Extensive changes to permit symbols to contain any expression
52 type and to delay the computation of the expression until the
53 value is actually needed. This permits setting symbols to values
54 calculated based on object code size. Expressions were changed to
55 no longer be in a section, to stop the overloading of segment and

208 (macro): Call mips_emit_delays before setting mips_noreorder.
209 Increment and decrement mips_noreorder rather than using
210 save_reorder_condition. Don't bother to use noreorder in

1501 prototypes for all static functions. Moved existing minimal
1502 debugging format support info #ifndef OBJ_ECOFF blocks.

1553 * read.c (s_ignore): Don't declare is_end_of_line. It's
1554 redundant, and triggers a VMS gcc compiler bug.
1556 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1557 current segment as an argument. (Ignored in all cases but VMS.)
1558 All callers and definitions changed.

1875 (operand): Treat zero byte as end-of-operand.
1877 * configure.in (per-target): Look for with_bfd_assembler option.
1878 For now, only accept "no", until the merge is done.
1880 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1881 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1882 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1883 * read.c: Finish conversion to S_* macros in the VMS only
1884 parts of the program. Add "const" modifier to hex_value.
1885 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
1887 * expr.c: Add "const" modifier to hex_value.
1888 * symbols.c: Finish conversion to S_* macros in the VMS only
1889 parts of the program. Add "const" modifier to
1890 md_[long,short]_jump_size. Remove declaration of const_flag
1891 (which will be declared in obj-vms.h).
1892 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1893 Fix arguments to VMS_write_object_file.
1894 * config-gas.com: New file. Script for VMS systems to set up the
1895 configuration to build gas for VMS, and create config.status.

1911 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1912 as symbols as well in the object file. Look for external functions

1951 (big_section, reg_section, pass1_section, diff_section,
1952 absent_section, text_section, data_section, bss_section): If
1953 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
1954 mapping to segT enum values.
1955 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1956 if these are used or defined, if BFD_ASSEMBLER.
1957 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

1962 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1964 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1965 declare with format attribute for -Wformat checking.
1967 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
1969 * app.c, config/tc-*.c: Don't include read.h, since it is already
1972 * These are based on patches from Minh Tran-le
1973 <mtranle@paris.intellicorp.com>.
1974 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1975 obj_format coffbfd and gas_target i386coff for target.
1976 (i[34]86-*-isc*): New host (uses sysv).
1977 * config/i386aix.mt: Removed (no longer used).
1978 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
1980 (LDFLAGS): Added, defined as -shlib.
1981 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1982 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1983 (DOT_LABEL_PREFIX): Define.
1984 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1985 name rather than L0\001.
1986 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
1988 * symbols.c, symbols.h (local_bss_counter): Removed.
1989 * write.c (write_object_file): bss no longer uses

1997 (size_section): Restored sanity check.
1998 (do_relocs_for): Base section address on s_paddr rather than
1999 computing it. Adjust a29k R_IHIHALF special case to account for
2000 section paddr (used to require paddr to be zero). If there are no
2001 reclos, set s_relptr to 0. Set relocation size in object_headers.
2002 (fill_section): Always set s_vaddr here, removing
2003 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2004 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2005 Set STYP_INFO for .comment.

2009 H_{SET,GET}_* macros.
2010 (do_linenos_for): Set lineno size in object_headers.
2011 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2012 set s_vaddr here. If string_byte_count remains 4, set it back to
2013 0, and only write strings out if there are some. Call
2014 fill_section before do_relocs_for and do_linenos_for.
2015 (obj_coff_section): Handle optional quoted second argument giving
2016 section characteristics.
2017 (obj_coff_bss): Added to handle .bss.
2018 (obj_coff_ident): Added to handle .ident (puts string in .comment
2020 (obj_coff_lcomm): Put common symbols in .bss, not .data.
2021 (fixup_mdeps): Change to segment. Call frag_wane after
2023 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2024 adjustment (already happened only for common symbols, but this is

2038 (do_scrub_next_char): For \", return " not '.
2039 (symbol_chars): Now const.
2041 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2042 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2044 * config/obj-coff.h: Don't use #elif.
2046 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2047 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2074 using ZERO_BASED_SEGMENTS.
2075 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2076 never set segment address for SEG_E2 (.bss) and don't write out
2077 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2078 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2079 definitions, and don't merge tags with non-tags. Check for .bf
2080 rather than just checking whether the second character is b and
2081 the third character is f.
2082 (obj_coff_val): gcc can generate values which we don't handle
2083 correctly; discard information for now, since it only affects the
2084 debugging information.

2086 (yank_symbols): Don't merge labels.
2087 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2232 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
2233 could be doing emulation.
2235 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2238 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2267 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2269 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2270 constant will not fit in an immediate field.
2271 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2306 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2308 * Support for i386-sysv.
2309 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

2333 * tc-m68k.c (get_num): make it work for all segments, not just the
2336 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

2347 * tc-z8k.c: lots of bug fixes
2349 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2351 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2352 #elif, since it is not supported by old compilers.
2353 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2354 couple of expressions in tc-m68k.c.
2356 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2358 * read.c (cons): If NO_RELOC is defined, use it.
2360 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2362 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2364 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2365 local labels to start with a .) and set REGISTER_PREFIX to %.
2366 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2368 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2370 * messages.c: Comment changes.
2372 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

2379 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2382 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2384 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2385 sections starting from zero, rather than making them consecutive.
2386 This makes subsequent reloc calculations easier, esp if the object
2387 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2388 allocate lcomm in .data rather than in .bss. It seems that some
2389 tools can't cope with a non-zero sized bss before linkage.
2391 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2393 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2394 throughout. That enum no longer means what we thought it meant.
2396 * tc-m68k.c (md_assemble, md_parse_option): Handle new
2397 "-mno-688[58]1" options.
2399 * tc-m68k.c: Added CPU32 support.
2401 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

2407 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
2408 Change LIBDEPS dependence to LIBS.
2410 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
2412 * Makefile.in (install): if $(tooldir) exists, install as in
2415 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2417 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2418 .word is < -32768 or > 32767. The -J flag causes the error to be
2419 ignored. This is to catch over-sized switches generated by gcc on
2420 systems which don't support the broken .word hack.
2421 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2422 write.c (fixup_segment): check for signed .word overflow if
2423 WARN_SIGNED_OVERFLOW_WORD.
2425 * write.c (fixup_segment): fixed missing parens in expression
2426 checking for byte or word overflow.
2428 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

2910 machine is a SPARC or a 29K.
2911 * config/obj-aout.c: added s_sect pseudo op
2912 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2913 fill in the timestamp.

2925 * read.c, write.c subsegs.c: back out the .bss changes.
2927 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2929 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

2935 * symbols.c (local_label_name): symbols now start with ^A.
2937 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2938 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2939 generate these sections. .align: will use NOP_OPCODE or 0
2940 for padding. This is just for being nice to the
2943 * expr.c (operand): changed to generate local label "\001L0"
2944 starting with a ^A so that it is recognized as a local label.
2946 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2948 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2949 i/o opcodes - inb, inw, outb and outw. string manipulation with
2950 att syntax - scmp, slod, smov, ssca, ssto.
2952 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2953 to just after .file .
2955 In obj_crawl_symbol_chain() where it tries to put the external
2956 symbols apart, with the condition:
2957 (!S_IS_DEFINED(symbolP) &&
2958 !S_IS_DEBUG(symbolP) &&
2959 !SF_GET_STATICS(symbolP))
2960 it was moving too many symbols out. So I switch it back to the
2962 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2964 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2965 so that we don't use the F_RELFLG which make the linker complain
2966 that somebody has stripped the relocation info.
2968 Also, the AIX ld program require that the relocation table
2969 is sorted by r_vaddr like the standard ATT assembler does.
2971 [he also changed the sizeof(struct ...)'s into the coff
2972 style FOOSZ macros. I'm not sure this is right, but I can't
2973 remember why. xoxorich.]

2977 * Makefile.in, configure.in, doc: use the doc. Build it, install
2980 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2982 * read.c: white space and comments only.
2984 * configure.in: use the new atof-ns32.c for ns32k.
2986 * write.c: comment change only.
2988 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2989 aren't yet integrated.
2991 * tc-i860.[hc]: blew off the dust. Something must still be done
2992 about conflicting relocation types.
2994 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2997 * tc-i960.c, tc-sparc.c: white space and comments only.
2999 * tc-a29k.h: delete duplicate macro definition.
3001 * new file atof-ns32k.c copied from hack's last unreleased gas.
3003 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3005 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3008 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3009 ChangeLog's prior to this are sketchy at best. I have logs.
3010 They just aren't ChangeLogs.
