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

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

135 section name. Don't crash on invalid strings.
136 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
139 * config/obj-elf.h: Don't include struc-symbol.h.

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

1489 prototypes for all static functions. Moved existing minimal
1490 debugging format support info #ifndef OBJ_ECOFF blocks.

1539 * make-gas.com: Find obstack.obj if it's not in the current
1541 * read.c (s_ignore): Don't declare is_end_of_line. It's
1542 redundant, and triggers a VMS gcc compiler bug.
1544 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1545 current segment as an argument. (Ignored in all cases but VMS.)
1546 All callers and definitions changed.

1863 (operand): Treat zero byte as end-of-operand.
1865 * configure.in (per-target): Look for with_bfd_assembler option.
1866 For now, only accept "no", until the merge is done.
1868 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1869 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

1875 * expr.c: Add "const" modifier to hex_value.
1876 * symbols.c: Finish conversion to S_* macros in the VMS only
1877 parts of the program. Add "const" modifier to
1878 md_[long,short]_jump_size. Remove declaration of const_flag
1879 (which will be declared in obj-vms.h).
1880 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1881 Fix arguments to VMS_write_object_file.
1882 * config-gas.com: New file. Script for VMS systems to set up the
1883 configuration to build gas for VMS, and create config.status.

1891 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1892 types of malformed stabs. Change parsing algorithm so that we are

1899 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1900 as symbols as well in the object file. Look for external functions

1902 g++ compiler is incapable of doing this.
1903 * tc-vax.c: Add '1' option for backward compatibility with older GCC
1905 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

1942 mapping to segT enum values.
1943 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1944 if these are used or defined, if BFD_ASSEMBLER.
1945 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
1946 subseg_new split into two functions.
1947 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
1949 * as.h (volatile): Don't define if already defined.
1950 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1952 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1953 declare with format attribute for -Wformat checking.
1955 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
1957 * app.c, config/tc-*.c: Don't include read.h, since it is already
1960 * These are based on patches from Minh Tran-le
1961 <mtranle@paris.intellicorp.com>.
1962 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1963 obj_format coffbfd and gas_target i386coff for target.
1964 (i[34]86-*-isc*): New host (uses sysv).
1965 * config/i386aix.mt: Removed (no longer used).
1966 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
1968 (LDFLAGS): Added, defined as -shlib.
1969 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1970 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1971 (DOT_LABEL_PREFIX): Define.
1972 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1973 name rather than L0\001.
1974 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
1976 * symbols.c, symbols.h (local_bss_counter): Removed.
1977 * write.c (write_object_file): bss no longer uses
1978 local_bss_counter. Pass correct data and bss size to
1979 VMS_write_object_file.

1985 (size_section): Restored sanity check.
1986 (do_relocs_for): Base section address on s_paddr rather than
1987 computing it. Adjust a29k R_IHIHALF special case to account for
1988 section paddr (used to require paddr to be zero). If there are no
1989 reclos, set s_relptr to 0. Set relocation size in object_headers.
1990 (fill_section): Always set s_vaddr here, removing
1991 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
1992 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
1993 Set STYP_INFO for .comment.

1997 H_{SET,GET}_* macros.
1998 (do_linenos_for): Set lineno size in object_headers.
1999 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2000 set s_vaddr here. If string_byte_count remains 4, set it back to
2001 0, and only write strings out if there are some. Call
2002 fill_section before do_relocs_for and do_linenos_for.
2003 (obj_coff_section): Handle optional quoted second argument giving
2004 section characteristics.
2005 (obj_coff_bss): Added to handle .bss.
2006 (obj_coff_ident): Added to handle .ident (puts string in .comment
2008 (obj_coff_lcomm): Put common symbols in .bss, not .data.
2009 (fixup_mdeps): Change to segment. Call frag_wane after
2011 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2012 adjustment (already happened only for common symbols, but this is
2014 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

2026 (do_scrub_next_char): For \", return " not '.
2027 (symbol_chars): Now const.
2029 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2030 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2032 * config/obj-coff.h: Don't use #elif.
2034 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2035 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2062 using ZERO_BASED_SEGMENTS.
2063 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2064 never set segment address for SEG_E2 (.bss) and don't write out
2065 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2066 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2067 definitions, and don't merge tags with non-tags. Check for .bf
2068 rather than just checking whether the second character is b and
2069 the third character is f.
2070 (obj_coff_val): gcc can generate values which we don't handle
2071 correctly; discard information for now, since it only affects the
2072 debugging information.

2074 (yank_symbols): Don't merge labels.
2075 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2220 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
2221 could be doing emulation.
2223 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2226 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
2229 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
2231 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

2255 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2257 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2258 constant will not fit in an immediate field.
2259 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2294 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2296 * Support for i386-sysv.
2297 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

2321 * tc-m68k.c (get_num): make it work for all segments, not just the
2324 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
2326 * configure.in: recognize i386-*-bsd emulation.

2335 * tc-z8k.c: lots of bug fixes
2337 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2339 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2340 #elif, since it is not supported by old compilers.
2341 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2342 couple of expressions in tc-m68k.c.
2344 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2346 * read.c (cons): If NO_RELOC is defined, use it.
2348 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2350 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2352 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2353 local labels to start with a .) and set REGISTER_PREFIX to %.
2354 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2356 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2358 * messages.c: Comment changes.
2360 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

2363 * messages.c: If __STDC__ is not defined, define NO_STDARG.
2365 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
2367 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2370 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2372 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2373 sections starting from zero, rather than making them consecutive.
2374 This makes subsequent reloc calculations easier, esp if the object
2375 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2376 allocate lcomm in .data rather than in .bss. It seems that some
2377 tools can't cope with a non-zero sized bss before linkage.
2379 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2381 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2382 throughout. That enum no longer means what we thought it meant.
2384 * tc-m68k.c (md_assemble, md_parse_option): Handle new
2385 "-mno-688[58]1" options.
2387 * tc-m68k.c: Added CPU32 support.
2389 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

2395 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
2396 Change LIBDEPS dependence to LIBS.
2398 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
2400 * Makefile.in (install): if $(tooldir) exists, install as in
2403 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2405 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2406 .word is < -32768 or > 32767. The -J flag causes the error to be
2407 ignored. This is to catch over-sized switches generated by gcc on
2408 systems which don't support the broken .word hack.
2409 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2410 write.c (fixup_segment): check for signed .word overflow if
2411 WARN_SIGNED_OVERFLOW_WORD.
2413 * write.c (fixup_segment): fixed missing parens in expression
2414 checking for byte or word overflow.
2416 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
2417 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
2418 WARN_SIGNED_OVERFLOW_WORD.

2421 expression checking for byte or word overflow.
2423 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2425 Support for i386 coff
2426 * obj-coffbfd.h : added stuff
2427 * tc-i386.c (tc_coff_fix2rtype): new function

2527 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2528 written with indirection on the last two operands, which can be

2530 which accepts either register type. Added '(' to notend stuff in
2531 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2870 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2872 * expr.c: If an expression is single comma, then return with
2873 SEG_ABSENT rather than an error - since the sparc front end does
2874 really strange things with things like fbge,a
2876 * as.h: include bfd.h if using many sections
2877 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2878 local labels didn't work.
2879 * listing.c (list_symbol_table): don't core dump when there's no
2881 * write.c, write.h: call fix_new with the right number of args on
2883 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2886 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2888 * app.c: MRI compatibility - allow single quote to start a string.
2889 * as.c: fix typo recently introduced.
2890 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2891 * expr.c: Much rewriting, to accomodate MRI syntax for
2892 expressions. Also easier to read now.
2893 * listing.c: Put back defuns
2894 * read.c: modified to accept MRI syntax, put back listing pseudo
2895 ops so that an assembler built with NO_LISTING ignores list ops
2897 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2898 machine is a SPARC or a 29K.
2899 * config/obj-aout.c: added s_sect pseudo op
2900 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2901 fill in the timestamp.
2902 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2903 anymore, define all the relocs which the tc-<x> bit will use so we
2904 can translate from them to the coff types.
2905 * config/tc-a29k.c: reloc_type isn't ane enum any more
2906 * config/tc-m68k.c: Added NO_RELOC definition.

2921 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2923 * symbols.c (local_label_name): symbols now start with ^A.
2925 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2926 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2927 generate these sections. .align: will use NOP_OPCODE or 0
2928 for padding. This is just for being nice to the
2931 * expr.c (operand): changed to generate local label "\001L0"
2932 starting with a ^A so that it is recognized as a local label.
2934 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2936 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2937 i/o opcodes - inb, inw, outb and outw. string manipulation with
2938 att syntax - scmp, slod, smov, ssca, ssto.
2940 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2941 to just after .file .
2943 In obj_crawl_symbol_chain() where it tries to put the external
2944 symbols apart, with the condition:
2945 (!S_IS_DEFINED(symbolP) &&
2946 !S_IS_DEBUG(symbolP) &&
2947 !SF_GET_STATICS(symbolP))
2948 it was moving too many symbols out. So I switch it back to the
2950 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2952 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2953 so that we don't use the F_RELFLG which make the linker complain
2954 that somebody has stripped the relocation info.
2956 Also, the AIX ld program require that the relocation table
2957 is sorted by r_vaddr like the standard ATT assembler does.
2959 [he also changed the sizeof(struct ...)'s into the coff
2960 style FOOSZ macros. I'm not sure this is right, but I can't
2961 remember why. xoxorich.]

2965 * Makefile.in, configure.in, doc: use the doc. Build it, install
2968 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2970 * read.c: white space and comments only.
2972 * configure.in: use the new atof-ns32.c for ns32k.
2974 * write.c: comment change only.
2976 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2977 aren't yet integrated.
2979 * tc-i860.[hc]: blew off the dust. Something must still be done
2980 about conflicting relocation types.
2982 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2985 * tc-i960.c, tc-sparc.c: white space and comments only.
2987 * tc-a29k.h: delete duplicate macro definition.
2989 * new file atof-ns32k.c copied from hack's last unreleased gas.
2991 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
2993 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
2996 * nearly everything. flush ChangeLog, package as gas-1.92.1.
2997 ChangeLog's prior to this are sketchy at best. I have logs.
2998 They just aren't ChangeLogs.
