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

83 r_offset field of the reloc to the fixup offset.
84 (fixup_segments): If TC_M88K, don't warn about fixup overflows.

87 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
89 * Extensive changes to permit symbols to contain any expression
90 type and to delay the computation of the expression until the
91 value is actually needed. This permits setting symbols to values
92 calculated based on object code size. Expressions were changed to
93 no longer be in a section, to stop the overloading of segment and
94 expression type that previously occurred.

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

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

1434 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
1436 * Makefile.in: add dvi target; as-$(config).texinfo might live in
1437 srcdir, might be in objdir.

1461 dropping a space immediately following an identifier.

1464 * config/tc-mips.c (macro): Use $AT if target register is zero in
1465 load instruction, which it can be for a floating point load.
1467 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

1592 redundant, and triggers a VMS gcc compiler bug.
1594 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1595 current segment as an argument. (Ignored in all cases but VMS.)

1913 (operand): Treat zero byte as end-of-operand.
1915 * configure.in (per-target): Look for with_bfd_assembler option.
1916 For now, only accept "no", until the merge is done.
1918 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1919 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1920 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1921 * read.c: Finish conversion to S_* macros in the VMS only
1922 parts of the program. Add "const" modifier to hex_value.
1923 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
1925 * expr.c: Add "const" modifier to hex_value.
1926 * symbols.c: Finish conversion to S_* macros in the VMS only
1927 parts of the program. Add "const" modifier to
1928 md_[long,short]_jump_size. Remove declaration of const_flag
1929 (which will be declared in obj-vms.h).
1930 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1931 Fix arguments to VMS_write_object_file.
1932 * config-gas.com: New file. Script for VMS systems to set up the
1933 configuration to build gas for VMS, and create config.status.

1945 resolve the data types of as many struct elements as possible
1946 when some part of the struct is not fully defined by the compiler.
1947 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
1949 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1950 as symbols as well in the object file. Look for external functions

1957 have the name of the source file yet.
1958 * config/ho-vms.h: define HO_VMS, not HO_VAX.
1960 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
1962 * read.c (s_data): Always use "data_section", since it'll map to
1963 SEG_DATA or SEG_E1 if needed.
1964 (s_lcomm): Likewise with bss_section.
1965 (s_fill): Use memset, not bzero.
1967 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

1979 * Changes for BFD_ASSEMBLER:
1980 * obj.h (obj_crawl_symbol_chain): Declare only if not
1982 (obj_header_append, obj_pre_write_hook): Ditto.
1983 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
1984 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

1994 if these are used or defined, if BFD_ASSEMBLER.
1995 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

2003 declare with format attribute for -Wformat checking.
2005 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2007 * app.c, config/tc-*.c: Don't include read.h, since it is already
2010 * These are based on patches from Minh Tran-le
2011 <mtranle@paris.intellicorp.com>.
2012 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2013 obj_format coffbfd and gas_target i386coff for target.
2014 (i[34]86-*-isc*): New host (uses sysv).
2015 * config/i386aix.mt: Removed (no longer used).
2016 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2018 (LDFLAGS): Added, defined as -shlib.
2019 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2020 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2021 (DOT_LABEL_PREFIX): Define.
2022 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2023 name rather than L0\001.

2035 (size_section): Restored sanity check.
2036 (do_relocs_for): Base section address on s_paddr rather than
2037 computing it. Adjust a29k R_IHIHALF special case to account for
2038 section paddr (used to require paddr to be zero). If there are no
2039 reclos, set s_relptr to 0. Set relocation size in object_headers.
2040 (fill_section): Always set s_vaddr here, removing
2041 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set

2048 (do_linenos_for): Set lineno size in object_headers.
2049 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2050 set s_vaddr here. If string_byte_count remains 4, set it back to
2051 0, and only write strings out if there are some. Call
2052 fill_section before do_relocs_for and do_linenos_for.
2053 (obj_coff_section): Handle optional quoted second argument giving
2054 section characteristics.
2055 (obj_coff_bss): Added to handle .bss.
2056 (obj_coff_ident): Added to handle .ident (puts string in .comment

2059 (fixup_mdeps): Change to segment. Call frag_wane after
2061 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2062 adjustment (already happened only for common symbols, but this is

2076 (do_scrub_next_char): For \", return " not '.
2077 (symbol_chars): Now const.
2079 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2080 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2082 * config/obj-coff.h: Don't use #elif.
2084 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2085 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2114 never set segment address for SEG_E2 (.bss) and don't write out
2115 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2116 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2117 definitions, and don't merge tags with non-tags. Check for .bf
2118 rather than just checking whether the second character is b and
2119 the third character is f.
2120 (obj_coff_val): gcc can generate values which we don't handle
2121 correctly; discard information for now, since it only affects the
2122 debugging information.

2124 (yank_symbols): Don't merge labels.
2125 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2273 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2276 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2305 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2307 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2308 constant will not fit in an immediate field.
2309 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2385 * tc-z8k.c: lots of bug fixes
2387 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2389 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2390 #elif, since it is not supported by old compilers.
2391 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2392 couple of expressions in tc-m68k.c.
2394 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2396 * read.c (cons): If NO_RELOC is defined, use it.
2398 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2400 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2402 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2403 local labels to start with a .) and set REGISTER_PREFIX to %.
2404 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2406 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2408 * messages.c: Comment changes.
2410 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

2420 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2422 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2423 sections starting from zero, rather than making them consecutive.
2424 This makes subsequent reloc calculations easier, esp if the object
2425 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2426 allocate lcomm in .data rather than in .bss. It seems that some
2427 tools can't cope with a non-zero sized bss before linkage.

2431 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2432 throughout. That enum no longer means what we thought it meant.

2453 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2455 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2456 .word is < -32768 or > 32767. The -J flag causes the error to be
2457 ignored. This is to catch over-sized switches generated by gcc on
2458 systems which don't support the broken .word hack.
2459 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2460 write.c (fixup_segment): check for signed .word overflow if
2461 WARN_SIGNED_OVERFLOW_WORD.

2490 From Steve Chamberlain:
2491 Makefile.in: Handle m68*-*-coff*.
2492 read.c, read.h: add mult argument to s_space
2494 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

2539 * config/tc-m68k.c (init_table): Now const. Always include 68851
2540 data, so that "bc" is available to 68040 cache instructions.
2541 Added "tt0", "tt1", and 68ec030 variants.
2542 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2543 (enum _register): Added TT0, TT1.
2544 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass

2571 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2572 has already been formatted (but may still contain %-characters).
2575 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2577 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2578 written with indirection on the last two operands, which can be
2579 either data or address registers. Added a new operand type 'r'
2580 which accepts either register type. Added '(' to notend stuff in
2581 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2928 local labels didn't work.
2929 * listing.c (list_symbol_table): don't core dump when there's no
2931 * write.c, write.h: call fix_new with the right number of args on
2933 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2936 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2938 * app.c: MRI compatibility - allow single quote to start a string.
2939 * as.c: fix typo recently introduced.
2940 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2941 * expr.c: Much rewriting, to accomodate MRI syntax for
2942 expressions. Also easier to read now.
2943 * listing.c: Put back defuns
2944 * read.c: modified to accept MRI syntax, put back listing pseudo
2945 ops so that an assembler built with NO_LISTING ignores list ops
2947 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2948 machine is a SPARC or a 29K.
2949 * config/obj-aout.c: added s_sect pseudo op
2950 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2951 fill in the timestamp.
2952 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2953 anymore, define all the relocs which the tc-<x> bit will use so we
2954 can translate from them to the coff types.
2955 * config/tc-a29k.c: reloc_type isn't ane enum any more
2956 * config/tc-m68k.c: Added NO_RELOC definition.
2958 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2960 * Makefile.in: put header files before C source for TAGS; remove
2961 references to non-existent syscalls.h.
2963 * read.c, write.c subsegs.c: back out the .bss changes.
2965 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2967 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2971 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2973 * symbols.c (local_label_name): symbols now start with ^A.
2975 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2976 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2977 generate these sections. .align: will use NOP_OPCODE or 0
2978 for padding. This is just for being nice to the
2981 * expr.c (operand): changed to generate local label "\001L0"
2982 starting with a ^A so that it is recognized as a local label.
2984 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2986 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2987 i/o opcodes - inb, inw, outb and outw. string manipulation with
2988 att syntax - scmp, slod, smov, ssca, ssto.
2990 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2991 to just after .file .
2993 In obj_crawl_symbol_chain() where it tries to put the external
2994 symbols apart, with the condition:
2995 (!S_IS_DEFINED(symbolP) &&
2996 !S_IS_DEBUG(symbolP) &&
2997 !SF_GET_STATICS(symbolP))
2998 it was moving too many symbols out. So I switch it back to the
3000 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3002 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3003 so that we don't use the F_RELFLG which make the linker complain
3004 that somebody has stripped the relocation info.
3006 Also, the AIX ld program require that the relocation table
3007 is sorted by r_vaddr like the standard ATT assembler does.
3009 [he also changed the sizeof(struct ...)'s into the coff
3010 style FOOSZ macros. I'm not sure this is right, but I can't
3011 remember why. xoxorich.]
3013 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3015 * Makefile.in, configure.in, doc: use the doc. Build it, install
3018 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3020 * read.c: white space and comments only.
3022 * configure.in: use the new atof-ns32.c for ns32k.
3024 * write.c: comment change only.
3026 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3027 aren't yet integrated.
3029 * tc-i860.[hc]: blew off the dust. Something must still be done
3030 about conflicting relocation types.
3032 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3035 * tc-i960.c, tc-sparc.c: white space and comments only.
3037 * tc-a29k.h: delete duplicate macro definition.
3039 * new file atof-ns32k.c copied from hack's last unreleased gas.
3041 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3043 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3046 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3047 ChangeLog's prior to this are sketchy at best. I have logs.
3048 They just aren't ChangeLogs.
