18 are also magic, and have special default flag settings.
19 (obj_elf_frob_symbol): Since the return value from this function
20 isn't used, don't bother calling obj_elf_write_symbol_p, since it
21 doesn't accomplish anything else.

26 * symbols.c: Don't define DEBUG by default.
28 Thu Jul 22 12:09:41 1993 Ian Lance Taylor (ian@cygnus.com)

32 * expr.c (expr): Don't let absolute_section override
33 undefined_section for the return value.

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

77 r_offset field of the reloc to the fixup offset.
78 (fixup_segments): If TC_M88K, don't warn about fixup overflows.
79 * doc/as.texinfo: Minor updates.
81 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
83 * Extensive changes to permit symbols to contain any expression
84 type and to delay the computation of the expression until the
85 value is actually needed. This permits setting symbols to values
86 calculated based on object code size. Expressions were changed to
87 no longer be in a section, to stop the overloading of segment and
88 expression type that previously occurred.

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

1428 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
1430 * Makefile.in: add dvi target; as-$(config).texinfo might live in
1431 srcdir, might be in objdir.

1586 redundant, and triggers a VMS gcc compiler bug.
1588 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1589 current segment as an argument. (Ignored in all cases but VMS.)

1907 (operand): Treat zero byte as end-of-operand.
1909 * configure.in (per-target): Look for with_bfd_assembler option.
1910 For now, only accept "no", until the merge is done.
1912 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1913 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1914 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1915 * read.c: Finish conversion to S_* macros in the VMS only
1916 parts of the program. Add "const" modifier to hex_value.
1917 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
1919 * expr.c: Add "const" modifier to hex_value.
1920 * symbols.c: Finish conversion to S_* macros in the VMS only
1921 parts of the program. Add "const" modifier to
1922 md_[long,short]_jump_size. Remove declaration of const_flag
1923 (which will be declared in obj-vms.h).
1924 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1925 Fix arguments to VMS_write_object_file.
1926 * config-gas.com: New file. Script for VMS systems to set up the
1927 configuration to build gas for VMS, and create config.status.

1943 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1944 as symbols as well in the object file. Look for external functions

1954 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
1956 * read.c (s_data): Always use "data_section", since it'll map to
1957 SEG_DATA or SEG_E1 if needed.
1958 (s_lcomm): Likewise with bss_section.
1959 (s_fill): Use memset, not bzero.
1961 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

1977 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
1978 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

1997 declare with format attribute for -Wformat checking.
1999 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2001 * app.c, config/tc-*.c: Don't include read.h, since it is already
2004 * These are based on patches from Minh Tran-le
2005 <mtranle@paris.intellicorp.com>.
2006 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2007 obj_format coffbfd and gas_target i386coff for target.
2008 (i[34]86-*-isc*): New host (uses sysv).
2009 * config/i386aix.mt: Removed (no longer used).
2010 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2012 (LDFLAGS): Added, defined as -shlib.
2013 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2014 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2015 (DOT_LABEL_PREFIX): Define.
2016 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2017 name rather than L0\001.

2029 (size_section): Restored sanity check.
2030 (do_relocs_for): Base section address on s_paddr rather than
2031 computing it. Adjust a29k R_IHIHALF special case to account for
2032 section paddr (used to require paddr to be zero). If there are no
2033 reclos, set s_relptr to 0. Set relocation size in object_headers.
2034 (fill_section): Always set s_vaddr here, removing
2035 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set

2043 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2044 set s_vaddr here. If string_byte_count remains 4, set it back to
2045 0, and only write strings out if there are some. Call
2046 fill_section before do_relocs_for and do_linenos_for.
2047 (obj_coff_section): Handle optional quoted second argument giving
2048 section characteristics.
2049 (obj_coff_bss): Added to handle .bss.
2050 (obj_coff_ident): Added to handle .ident (puts string in .comment

2053 (fixup_mdeps): Change to segment. Call frag_wane after
2055 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2056 adjustment (already happened only for common symbols, but this is

2070 (do_scrub_next_char): For \", return " not '.
2071 (symbol_chars): Now const.
2073 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2074 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2076 * config/obj-coff.h: Don't use #elif.
2078 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2079 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2108 never set segment address for SEG_E2 (.bss) and don't write out
2109 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2110 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2111 definitions, and don't merge tags with non-tags. Check for .bf
2112 rather than just checking whether the second character is b and
2113 the third character is f.
2114 (obj_coff_val): gcc can generate values which we don't handle
2115 correctly; discard information for now, since it only affects the
2116 debugging information.

2118 (yank_symbols): Don't merge labels.
2119 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2267 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2270 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2301 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2302 constant will not fit in an immediate field.
2303 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2379 * tc-z8k.c: lots of bug fixes
2381 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2383 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2384 #elif, since it is not supported by old compilers.
2385 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2386 couple of expressions in tc-m68k.c.
2388 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2390 * read.c (cons): If NO_RELOC is defined, use it.
2392 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2394 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2396 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2397 local labels to start with a .) and set REGISTER_PREFIX to %.
2398 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2400 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2402 * messages.c: Comment changes.

2414 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2416 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2417 sections starting from zero, rather than making them consecutive.
2418 This makes subsequent reloc calculations easier, esp if the object
2419 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2420 allocate lcomm in .data rather than in .bss. It seems that some
2421 tools can't cope with a non-zero sized bss before linkage.
2423 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2425 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

2449 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2450 .word is < -32768 or > 32767. The -J flag causes the error to be
2451 ignored. This is to catch over-sized switches generated by gcc on
2452 systems which don't support the broken .word hack.
2453 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.

2533 * config/tc-m68k.c (init_table): Now const. Always include 68851
2534 data, so that "bc" is available to 68040 cache instructions.
2535 Added "tt0", "tt1", and 68ec030 variants.
2536 (md_assemble): Complain if 68000 (only) and 68881 are specified.

2565 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2566 has already been formatted (but may still contain %-characters).
2569 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2571 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2572 written with indirection on the last two operands, which can be
2573 either data or address registers. Added a new operand type 'r'
2574 which accepts either register type. Added '(' to notend stuff in
2575 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2932 * app.c: MRI compatibility - allow single quote to start a string.
2933 * as.c: fix typo recently introduced.
2934 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2935 * expr.c: Much rewriting, to accomodate MRI syntax for
2936 expressions. Also easier to read now.
2937 * listing.c: Put back defuns
2938 * read.c: modified to accept MRI syntax, put back listing pseudo
2939 ops so that an assembler built with NO_LISTING ignores list ops
2941 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2942 machine is a SPARC or a 29K.
2943 * config/obj-aout.c: added s_sect pseudo op
2944 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2945 fill in the timestamp.
2946 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2947 anymore, define all the relocs which the tc-<x> bit will use so we
2948 can translate from them to the coff types.
2949 * config/tc-a29k.c: reloc_type isn't ane enum any more
2950 * config/tc-m68k.c: Added NO_RELOC definition.

2954 * Makefile.in: put header files before C source for TAGS; remove
2955 references to non-existent syscalls.h.
2957 * read.c, write.c subsegs.c: back out the .bss changes.
2959 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2961 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2965 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2967 * symbols.c (local_label_name): symbols now start with ^A.
2969 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2970 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2971 generate these sections. .align: will use NOP_OPCODE or 0
2972 for padding. This is just for being nice to the
2975 * expr.c (operand): changed to generate local label "\001L0"
2976 starting with a ^A so that it is recognized as a local label.
2978 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2980 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2981 i/o opcodes - inb, inw, outb and outw. string manipulation with
2982 att syntax - scmp, slod, smov, ssca, ssto.
2984 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2985 to just after .file .
2987 In obj_crawl_symbol_chain() where it tries to put the external
2988 symbols apart, with the condition:
2989 (!S_IS_DEFINED(symbolP) &&
2990 !S_IS_DEBUG(symbolP) &&
2991 !SF_GET_STATICS(symbolP))
2992 it was moving too many symbols out. So I switch it back to the
2994 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2996 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2997 so that we don't use the F_RELFLG which make the linker complain
2998 that somebody has stripped the relocation info.
3000 Also, the AIX ld program require that the relocation table
3001 is sorted by r_vaddr like the standard ATT assembler does.
3003 [he also changed the sizeof(struct ...)'s into the coff
3004 style FOOSZ macros. I'm not sure this is right, but I can't
3005 remember why. xoxorich.]
3007 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3009 * Makefile.in, configure.in, doc: use the doc. Build it, install
3012 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3014 * read.c: white space and comments only.
3016 * configure.in: use the new atof-ns32.c for ns32k.
3018 * write.c: comment change only.
3020 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3021 aren't yet integrated.
3023 * tc-i860.[hc]: blew off the dust. Something must still be done
3024 about conflicting relocation types.
3026 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3029 * tc-i960.c, tc-sparc.c: white space and comments only.
3031 * tc-a29k.h: delete duplicate macro definition.
3033 * new file atof-ns32k.c copied from hack's last unreleased gas.
3035 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3037 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3040 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3041 ChangeLog's prior to this are sketchy at best. I have logs.
3042 They just aren't ChangeLogs.
