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

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

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

1495 prototypes for all static functions. Moved existing minimal
1496 debugging format support info #ifndef OBJ_ECOFF blocks.

1545 * make-gas.com: Find obstack.obj if it's not in the current
1547 * read.c (s_ignore): Don't declare is_end_of_line. It's
1548 redundant, and triggers a VMS gcc compiler bug.
1550 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1551 current segment as an argument. (Ignored in all cases but VMS.)
1552 All callers and definitions changed.

1869 (operand): Treat zero byte as end-of-operand.
1871 * configure.in (per-target): Look for with_bfd_assembler option.
1872 For now, only accept "no", until the merge is done.
1874 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1875 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1876 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1877 * read.c: Finish conversion to S_* macros in the VMS only
1878 parts of the program. Add "const" modifier to hex_value.

1881 * expr.c: Add "const" modifier to hex_value.
1882 * symbols.c: Finish conversion to S_* macros in the VMS only
1883 parts of the program. Add "const" modifier to
1884 md_[long,short]_jump_size. Remove declaration of const_flag
1885 (which will be declared in obj-vms.h).
1886 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1887 Fix arguments to VMS_write_object_file.
1888 * config-gas.com: New file. Script for VMS systems to set up the
1889 configuration to build gas for VMS, and create config.status.

1948 mapping to segT enum values.
1949 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1950 if these are used or defined, if BFD_ASSEMBLER.
1951 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

1955 * as.h (volatile): Don't define if already defined.
1956 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1958 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1959 declare with format attribute for -Wformat checking.
1961 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
1963 * app.c, config/tc-*.c: Don't include read.h, since it is already
1966 * These are based on patches from Minh Tran-le
1967 <mtranle@paris.intellicorp.com>.
1968 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1969 obj_format coffbfd and gas_target i386coff for target.
1970 (i[34]86-*-isc*): New host (uses sysv).
1971 * config/i386aix.mt: Removed (no longer used).
1972 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
1974 (LDFLAGS): Added, defined as -shlib.
1975 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1976 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1977 (DOT_LABEL_PREFIX): Define.
1978 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1979 name rather than L0\001.
1980 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
1982 * symbols.c, symbols.h (local_bss_counter): Removed.
1983 * write.c (write_object_file): bss no longer uses
1984 local_bss_counter. Pass correct data and bss size to
1985 VMS_write_object_file.

1991 (size_section): Restored sanity check.
1992 (do_relocs_for): Base section address on s_paddr rather than
1993 computing it. Adjust a29k R_IHIHALF special case to account for
1994 section paddr (used to require paddr to be zero). If there are no
1995 reclos, set s_relptr to 0. Set relocation size in object_headers.
1996 (fill_section): Always set s_vaddr here, removing
1997 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
1998 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
1999 Set STYP_INFO for .comment.

2004 (do_linenos_for): Set lineno size in object_headers.
2005 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2006 set s_vaddr here. If string_byte_count remains 4, set it back to
2007 0, and only write strings out if there are some. Call
2008 fill_section before do_relocs_for and do_linenos_for.
2009 (obj_coff_section): Handle optional quoted second argument giving
2010 section characteristics.
2011 (obj_coff_bss): Added to handle .bss.
2012 (obj_coff_ident): Added to handle .ident (puts string in .comment
2014 (obj_coff_lcomm): Put common symbols in .bss, not .data.
2015 (fixup_mdeps): Change to segment. Call frag_wane after
2017 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2018 adjustment (already happened only for common symbols, but this is

2032 (do_scrub_next_char): For \", return " not '.
2033 (symbol_chars): Now const.
2035 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2036 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2038 * config/obj-coff.h: Don't use #elif.
2040 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2041 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2068 using ZERO_BASED_SEGMENTS.
2069 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2070 never set segment address for SEG_E2 (.bss) and don't write out
2071 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2072 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2073 definitions, and don't merge tags with non-tags. Check for .bf
2074 rather than just checking whether the second character is b and
2075 the third character is f.
2076 (obj_coff_val): gcc can generate values which we don't handle
2077 correctly; discard information for now, since it only affects the
2078 debugging information.

2080 (yank_symbols): Don't merge labels.
2081 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2226 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
2227 could be doing emulation.
2229 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2232 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2261 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2263 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2264 constant will not fit in an immediate field.
2265 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2300 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2302 * Support for i386-sysv.
2303 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

2307 (fill_section): Don't set STYP_NOLOAD for .bss section.
2308 (fixup_segment): 386 uses strange common symbol format.

2327 * tc-m68k.c (get_num): make it work for all segments, not just the
2330 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

2341 * tc-z8k.c: lots of bug fixes
2343 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2345 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2346 #elif, since it is not supported by old compilers.
2347 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2348 couple of expressions in tc-m68k.c.
2350 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2352 * read.c (cons): If NO_RELOC is defined, use it.
2354 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2356 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2358 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2359 local labels to start with a .) and set REGISTER_PREFIX to %.
2360 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2362 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2364 * messages.c: Comment changes.
2366 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

2373 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2376 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2378 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2379 sections starting from zero, rather than making them consecutive.
2380 This makes subsequent reloc calculations easier, esp if the object
2381 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2382 allocate lcomm in .data rather than in .bss. It seems that some
2383 tools can't cope with a non-zero sized bss before linkage.
2385 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2387 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2388 throughout. That enum no longer means what we thought it meant.
2390 * tc-m68k.c (md_assemble, md_parse_option): Handle new
2391 "-mno-688[58]1" options.
2393 * tc-m68k.c: Added CPU32 support.

2401 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
2402 Change LIBDEPS dependence to LIBS.
2404 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
2406 * Makefile.in (install): if $(tooldir) exists, install as in
2409 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2411 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2412 .word is < -32768 or > 32767. The -J flag causes the error to be
2413 ignored. This is to catch over-sized switches generated by gcc on
2414 systems which don't support the broken .word hack.
2415 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2416 write.c (fixup_segment): check for signed .word overflow if
2417 WARN_SIGNED_OVERFLOW_WORD.
2419 * write.c (fixup_segment): fixed missing parens in expression
2420 checking for byte or word overflow.
2422 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
2423 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
2424 WARN_SIGNED_OVERFLOW_WORD.

2904 machine is a SPARC or a 29K.
2905 * config/obj-aout.c: added s_sect pseudo op
2906 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2907 fill in the timestamp.
2908 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2909 anymore, define all the relocs which the tc-<x> bit will use so we

2912 * config/tc-m68k.c: Added NO_RELOC definition.

2929 * symbols.c (local_label_name): symbols now start with ^A.
2931 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2932 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2933 generate these sections. .align: will use NOP_OPCODE or 0
2934 for padding. This is just for being nice to the
2937 * expr.c (operand): changed to generate local label "\001L0"
2938 starting with a ^A so that it is recognized as a local label.
2940 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2942 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2943 i/o opcodes - inb, inw, outb and outw. string manipulation with
2944 att syntax - scmp, slod, smov, ssca, ssto.
2946 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2947 to just after .file .
2949 In obj_crawl_symbol_chain() where it tries to put the external
2950 symbols apart, with the condition:
2951 (!S_IS_DEFINED(symbolP) &&
2952 !S_IS_DEBUG(symbolP) &&
2953 !SF_GET_STATICS(symbolP))
2954 it was moving too many symbols out. So I switch it back to the
2956 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2958 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2959 so that we don't use the F_RELFLG which make the linker complain
2960 that somebody has stripped the relocation info.
2962 Also, the AIX ld program require that the relocation table
2963 is sorted by r_vaddr like the standard ATT assembler does.
2965 [he also changed the sizeof(struct ...)'s into the coff
2966 style FOOSZ macros. I'm not sure this is right, but I can't
2967 remember why. xoxorich.]

2971 * Makefile.in, configure.in, doc: use the doc. Build it, install
2974 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2976 * read.c: white space and comments only.
2978 * configure.in: use the new atof-ns32.c for ns32k.
2980 * write.c: comment change only.
2982 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2983 aren't yet integrated.
2985 * tc-i860.[hc]: blew off the dust. Something must still be done
2986 about conflicting relocation types.
2988 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2991 * tc-i960.c, tc-sparc.c: white space and comments only.
2993 * tc-a29k.h: delete duplicate macro definition.
2995 * new file atof-ns32k.c copied from hack's last unreleased gas.
2997 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
2999 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3002 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3003 ChangeLog's prior to this are sketchy at best. I have logs.
3004 They just aren't ChangeLogs.
