165 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
167 * Extensive changes to permit symbols to contain any expression
168 type and to delay the computation of the expression until the
169 value is actually needed. This permits setting symbols to values
170 calculated based on object code size. Expressions were changed to

324 (macro): Call mips_emit_delays before setting mips_noreorder.
325 Increment and decrement mips_noreorder rather than using

400 segment rather than sy_forward.
401 * config/obj-vms.c (VMS_Check_For_Main): Don't initialize
402 sy_forward; do initialize sy_resolved and sy_resolving.
403 * config/tc-hppa.h (STAB_FIXUP): Use sy_value, not sy_forward.
405 * Changes to keep a full expression as the value of a symbol, not

1541 lines; I don't think that can be done portably.
1542 * config/tc-mips.c (macro): Use $AT if target register is zero in
1543 load instruction, which it can be for a floating point load.

1669 * read.c (s_ignore): Don't declare is_end_of_line. It's
1670 redundant, and triggers a VMS gcc compiler bug.
1672 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1673 current segment as an argument. (Ignored in all cases but VMS.)
1674 All callers and definitions changed.

1970 * config/tc-sparc.c (architecture_requested, warn_on_bump,
1971 md_relax_table): Use default zero initialization.
1972 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
1973 latter, instead of selecting with preprocessor conditionals.
1975 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1977 * configure.in: recognise all sparclite variants

1985 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
1987 * expr.c (operand): If character other than comma or newline is a
1988 logical end-of-line character, use the newline case.
1989 From Eric Youngdale:
1990 (operand): Set X_add_number field for floating-point numbers.
1991 (operand): Treat zero byte as end-of-operand.
1993 * configure.in (per-target): Look for with_bfd_assembler option.
1994 For now, only accept "no", until the merge is done.
1996 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1997 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1998 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1999 * read.c: Finish conversion to S_* macros in the VMS only
2000 parts of the program. Add "const" modifier to hex_value.

2003 * expr.c: Add "const" modifier to hex_value.
2004 * symbols.c: Finish conversion to S_* macros in the VMS only
2005 parts of the program. Add "const" modifier to
2006 md_[long,short]_jump_size. Remove declaration of const_flag
2007 (which will be declared in obj-vms.h).
2008 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2009 Fix arguments to VMS_write_object_file.
2010 * config-gas.com: New file. Script for VMS systems to set up the
2011 configuration to build gas for VMS, and create config.status.
2012 * make-gas.com: Redone to work with new scheme.
2013 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2015 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2016 will swap bytes if needed on a big endian system. Use throughout
2018 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2019 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2020 types of malformed stabs. Change parsing algorithm so that we are
2021 more certain of having all of the information that we need on hand.
2022 * obj-vms.c (final_forward_reference): New function, used to help
2023 resolve the data types of as many struct elements as possible
2024 when some part of the struct is not fully defined by the compiler.
2025 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
2027 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2028 as symbols as well in the object file. Look for external functions
2029 that start with "__vt.", and turn them into variables, since the
2030 g++ compiler is incapable of doing this.
2031 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2033 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2034 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2035 have the name of the source file yet.
2036 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2038 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2040 * read.c (s_data): Always use "data_section", since it'll map to
2041 SEG_DATA or SEG_E1 if needed.
2042 (s_lcomm): Likewise with bss_section.
2043 (s_fill): Use memset, not bzero.
2045 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2066 (section_alignment): Declare only if not BFD_ASSEMBLER.
2067 (big_section, reg_section, pass1_section, diff_section,
2068 absent_section, text_section, data_section, bss_section): If
2069 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2070 mapping to segT enum values.
2071 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2072 if these are used or defined, if BFD_ASSEMBLER.
2073 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2074 subseg_new split into two functions.
2075 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2077 * as.h (volatile): Don't define if already defined.
2078 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2080 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2081 declare with format attribute for -Wformat checking.
2083 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2085 * app.c, config/tc-*.c: Don't include read.h, since it is already
2088 * These are based on patches from Minh Tran-le
2089 <mtranle@paris.intellicorp.com>.
2090 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2091 obj_format coffbfd and gas_target i386coff for target.
2092 (i[34]86-*-isc*): New host (uses sysv).
2093 * config/i386aix.mt: Removed (no longer used).
2094 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2096 (LDFLAGS): Added, defined as -shlib.
2097 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2098 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2099 (DOT_LABEL_PREFIX): Define.
2100 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2101 name rather than L0\001.

2104 * symbols.c, symbols.h (local_bss_counter): Removed.
2105 * write.c (write_object_file): bss no longer uses
2106 local_bss_counter. Pass correct data and bss size to

2113 (size_section): Restored sanity check.
2114 (do_relocs_for): Base section address on s_paddr rather than
2115 computing it. Adjust a29k R_IHIHALF special case to account for
2116 section paddr (used to require paddr to be zero). If there are no
2117 reclos, set s_relptr to 0. Set relocation size in object_headers.
2118 (fill_section): Always set s_vaddr here, removing
2119 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2120 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2121 Set STYP_INFO for .comment.

2125 H_{SET,GET}_* macros.
2126 (do_linenos_for): Set lineno size in object_headers.
2127 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2128 set s_vaddr here. If string_byte_count remains 4, set it back to
2129 0, and only write strings out if there are some. Call
2130 fill_section before do_relocs_for and do_linenos_for.
2131 (obj_coff_section): Handle optional quoted second argument giving
2132 section characteristics.
2133 (obj_coff_bss): Added to handle .bss.
2134 (obj_coff_ident): Added to handle .ident (puts string in .comment

2154 (do_scrub_next_char): For \", return " not '.
2155 (symbol_chars): Now const.
2157 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2158 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2160 * config/obj-coff.h: Don't use #elif.
2162 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2163 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2189 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
2190 using ZERO_BASED_SEGMENTS.
2191 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2192 never set segment address for SEG_E2 (.bss) and don't write out
2193 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2194 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2195 definitions, and don't merge tags with non-tags. Check for .bf
2196 rather than just checking whether the second character is b and
2197 the third character is f.
2198 (obj_coff_val): gcc can generate values which we don't handle
2199 correctly; discard information for now, since it only affects the
2200 debugging information.

2202 (yank_symbols): Don't merge labels.
2203 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2430 (fixup_segment): 386 uses strange common symbol format.
2431 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
2432 compatibility with SVR3.2 linker.
2433 * configure.in: i386-sysv and i386-sco use coffbfd.

2444 fix i960+non-bfd coff bit rot.
2445 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
2446 support for C source listings. (obj_coff_endef): look in the right
2447 part of the symbol for the symbol name
2449 * tc-m68k.c (get_num): make it work for all segments, not just the
2452 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

2463 * tc-z8k.c: lots of bug fixes
2465 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2467 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2468 #elif, since it is not supported by old compilers.
2469 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2470 couple of expressions in tc-m68k.c.
2472 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2474 * read.c (cons): If NO_RELOC is defined, use it.
2476 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2478 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2480 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2481 local labels to start with a .) and set REGISTER_PREFIX to %.
2482 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2484 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

2500 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2501 sections starting from zero, rather than making them consecutive.
2502 This makes subsequent reloc calculations easier, esp if the object
2503 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2504 allocate lcomm in .data rather than in .bss. It seems that some
2505 tools can't cope with a non-zero sized bss before linkage.
2507 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2509 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

2531 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2533 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2534 .word is < -32768 or > 32767. The -J flag causes the error to be
2535 ignored. This is to catch over-sized switches generated by gcc on
2536 systems which don't support the broken .word hack.
2537 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2538 write.c (fixup_segment): check for signed .word overflow if
2539 WARN_SIGNED_OVERFLOW_WORD.
2541 * write.c (fixup_segment): fixed missing parens in expression
2542 checking for byte or word overflow.

2558 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2560 * input-scrub.c (input_scrub_push): call input_file_begin, not
2562 messages.c (as_perror): print ": " between the passed in error and
2563 the strerror, like perror does.
2565 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

2568 From Steve Chamberlain:
2569 Makefile.in: Handle m68*-*-coff*.
2570 read.c, read.h: add mult argument to s_space
2572 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2573 Motorola and MIT syntax; gas can now assemble either type of
2575 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2582 (fixup_segment) set fx_subsy to 0.
2583 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2585 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2588 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2590 * Makefile.in (LIBS): Include opcode library.

2615 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2617 * config/tc-m68k.c (init_table): Now const. Always include 68851
2618 data, so that "bc" is available to 68040 cache instructions.
2619 Added "tt0", "tt1", and 68ec030 variants.
2620 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2621 (enum _register): Added TT0, TT1.
2622 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2623 line number correctly in "internal error" messages. Don't print
2624 architecture-mismatch message for operand errors.

2649 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2650 has already been formatted (but may still contain %-characters).
2653 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2655 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2656 written with indirection on the last two operands, which can be
2657 either data or address registers. Added a new operand type 'r'
2658 which accepts either register type. Added '(' to notend stuff in
2659 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2913 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
2915 * Makefile.in: Changed some lines to be less confusing for some
2918 * input-file.c: Conditionalize on _IOFBF, not VMS.
2920 * read.c, write.c: Change a series of ifdef/elif to
2921 ifdef/else/ifdef etc.
2923 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
2925 * symbols.c (fb_label_init): fix sizeof to memset.
2927 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
2929 * Makefile.in: install the man page.
2931 * Makefile.in: pass down MAKEINFO explicitly on info.
2933 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
2935 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2937 * flonum-const.c: renamed flonum-konst.c to stop dos name
2940 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
2942 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
2943 tc-m68k.h to te-sun3.h.
2945 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
2947 * configure.in: vxworks68 gets te-sun3.h.
2949 * expr.c: remove limitation that local_labels_dollar or
2950 local_labels_fb must be < 10.
2952 * symbols.c: remove local_labels_dollar, replace with a function
2953 interface for a sparse array. All users adjusted.
2955 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
2957 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2959 * doc/Makefile.in: commented out line for building as-all.texinfo.
2962 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
2964 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
2966 * Makefile.in: added check target.
2968 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2970 * Makefile.in: added tooldir and program_prefix.
2972 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
2974 * write.{c,h} (fix_new): Make these declarations consistent.
2976 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
2978 * Makefile.in (strerror.o): Add rule so that broken Sun make can
2981 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
2983 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
2985 * expr.c (operand): if can't work out what sort of operand it is,
2986 then look through FLT_CHARS for a hint.
2988 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
2990 * Makefile.in, configure.in: removed traces of namesubdir,
2991 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2992 copyrights to '92, changed some from Cygnus to FSF.
2994 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
2995 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2996 copyrights to '92, changed some from Cygnus to FSF.
2998 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3000 * expr.c: If an expression is single comma, then return with
3001 SEG_ABSENT rather than an error - since the sparc front end does
3002 really strange things with things like fbge,a
3004 * as.h: include bfd.h if using many sections
3005 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3006 local labels didn't work.
3007 * listing.c (list_symbol_table): don't core dump when there's no
3009 * write.c, write.h: call fix_new with the right number of args on
3011 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3014 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3016 * app.c: MRI compatibility - allow single quote to start a string.
3017 * as.c: fix typo recently introduced.
3018 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3019 * expr.c: Much rewriting, to accomodate MRI syntax for
3020 expressions. Also easier to read now.
3021 * listing.c: Put back defuns
3022 * read.c: modified to accept MRI syntax, put back listing pseudo
3023 ops so that an assembler built with NO_LISTING ignores list ops
3025 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3026 machine is a SPARC or a 29K.
3027 * config/obj-aout.c: added s_sect pseudo op
3028 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3029 fill in the timestamp.
3030 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3031 anymore, define all the relocs which the tc-<x> bit will use so we
3032 can translate from them to the coff types.
3033 * config/tc-a29k.c: reloc_type isn't ane enum any more
3034 * config/tc-m68k.c: Added NO_RELOC definition.
3036 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3038 * Makefile.in: put header files before C source for TAGS; remove
3039 references to non-existent syscalls.h.
3041 * read.c, write.c subsegs.c: back out the .bss changes.
3043 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3045 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3049 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3051 * symbols.c (local_label_name): symbols now start with ^A.
3053 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3054 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3055 generate these sections. .align: will use NOP_OPCODE or 0
3056 for padding. This is just for being nice to the
3059 * expr.c (operand): changed to generate local label "\001L0"
3060 starting with a ^A so that it is recognized as a local label.
3062 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3064 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3065 i/o opcodes - inb, inw, outb and outw. string manipulation with
3066 att syntax - scmp, slod, smov, ssca, ssto.
3068 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3069 to just after .file .
3071 In obj_crawl_symbol_chain() where it tries to put the external
3072 symbols apart, with the condition:
3073 (!S_IS_DEFINED(symbolP) &&
3074 !S_IS_DEBUG(symbolP) &&
3075 !SF_GET_STATICS(symbolP))
3076 it was moving too many symbols out. So I switch it back to the
3078 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3080 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3081 so that we don't use the F_RELFLG which make the linker complain
3082 that somebody has stripped the relocation info.
3084 Also, the AIX ld program require that the relocation table
3085 is sorted by r_vaddr like the standard ATT assembler does.
3087 [he also changed the sizeof(struct ...)'s into the coff
3088 style FOOSZ macros. I'm not sure this is right, but I can't
3089 remember why. xoxorich.]
3091 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3093 * Makefile.in, configure.in, doc: use the doc. Build it, install
3096 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3098 * read.c: white space and comments only.
3100 * configure.in: use the new atof-ns32.c for ns32k.
3102 * write.c: comment change only.
3104 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3105 aren't yet integrated.
3107 * tc-i860.[hc]: blew off the dust. Something must still be done
3108 about conflicting relocation types.
3110 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3113 * tc-i960.c, tc-sparc.c: white space and comments only.
3115 * tc-a29k.h: delete duplicate macro definition.
3117 * new file atof-ns32k.c copied from hack's last unreleased gas.
3119 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3121 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3124 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3125 ChangeLog's prior to this are sketchy at best. I have logs.
3126 They just aren't ChangeLogs.
