221 all arguments have been processed.

490 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
491 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

494 (mips_force_relocation): New function.
495 (md_apply_fix): Set fixP->fx_done appropriately.

507 (load_address): Handle EMBEDDED_PIC.
508 (macro): Handle EMBEDDED_PIC in all PIC cases.
509 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
510 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
511 -non_shared to use NO_PIC (this is how the Irix 5 assembler
512 works). Do not permit -G with SVR4_PIC.
513 (s_abicalls): Warn if -G was used, and force -G 0.
514 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
515 anything but a.out, not just for ELF. For ECOFF, don't generate a
516 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
518 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
520 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

526 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
528 * Makefile.in (config-stamp): If `defs' is defined, emit a
529 preprocessor directive to create a macro named by this value into
530 config.new; don't explicitly go for BFD_ASSEMBLER.
531 * configure.in: Define `defs', not `BFDDEF'. Set it to
532 MANY_SEGMENTS for any obj-coffbfd target.
533 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
534 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
536 (LOCAL_LOADLIBES): Deleted.
537 * config/m68kcoff.mt (TDEFINES): Don't define those macros.

564 bfd_set_symtab is called.
565 (dump_section_relocs): Note whether a symbol is a section symbol
567 (adjust_reloc_syms): For now, always supply an absolute symbol for
568 fixups without symbols but not yet `done'. Use section_symbol to
569 get the symbol, instead of going directly for abs_symbol.
570 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
571 reloc is not a section symbol and is not in the symbol table.
572 (set_symtab): New function, broken out from write_object_file.
573 Counts symbol table instead of relying on an earlier count.
574 (write_object_file): Call set_symtab, but do it after potentially
575 invoking the *_frob_file macros. Don't bother counting symbols.
576 Call symbol_remove, instead of expanding it in place. Moved the
577 conditionalized `object_file_size' declaration down to
578 conditionalized block where it's used. When using the absolute
579 symbol for a fixup without a symbol, set sy_used_in_reloc.
580 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
581 the correct symbol for the absolute section.
583 * subsegs.c (section_symbol): Use symbol_new instead of
584 symbol_make, since we may want it to go into the symbol table.
585 Make the new symbol have internal linkage. If
586 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
587 symbol with the newly created GAS symbol.
588 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
589 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

596 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
597 (sparc_ip, label "immediate"): Reject constants for pcrel
598 instructions only if the relocation type indicates a "call"
599 instruction and the offset is within range of a "jmpl %g0". If
600 it's not in range, use the absolute section symbol plus an offset.
601 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
603 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
605 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
608 * configure.in: Eliminated all targets using obj-coff but not
609 defining BFD_ASSEMBLER; I think all such targets that are
610 supported will be matched by real CPU-OS combinations earlier in
612 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
613 some comments about the dpx2 configuration, but left it disabled,
614 since it couldn't be reached before.
615 (target a29k-amd-ebmonold): Deleted.
617 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

625 the 'j' operand if there are no further alternatives for this
628 * config/obj-coffbfd.c (adjust_stab_section): Initialize
629 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
630 is not SEG_UNKNOWN rather than checking whether it is >= 0.
632 * config/tc-mips.c (mips_align): Take new argument, label, and use
633 it instead of global insn_label.
634 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
635 call to mips_emit_delay and pass it to mips_align.
637 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
639 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
641 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
642 argument to a .callinfo directive. Don't loop forever on errors.
644 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
645 use pre-defined registers as arguments.
647 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
649 * write.c (write_object_file): Check both S_IS_LOCAL and
650 S_IS_EXTERNAL when deciding whether to discard a symbol.
652 * config-gas.com: Scan Makefile.in, not version.c, for current
653 version number. Delete all versions of temp files when finished
654 with them. Create config.h.
656 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
657 values to reduce number of lookups with S_GET_VALUE. Skip debug

659 holger@botbso.rhein-main.de.)
660 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
661 field. (Also from Holger Teutsch.) Watch for a would-be register
662 mask that spans frags.
664 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
665 this_base, not line_base. (Patch from Andreas Arens,
666 ari@obelix.av.rwth-aachen.de.)
668 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
669 look local if they're exported or undefined. Used to be done for
672 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

676 (lex_type): Use it for `%'.
678 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2390 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
2391 standard hpux include files to pick up various function decls.

2459 pass new argument for i, j and o cases.
2460 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2463 rather than hard coded constants.
2464 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

2681 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2682 the table, require that the one without bit 0x1000000 set come

2791 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
2793 * configure.in: Set bfd_gas for all sparc targets. Added facility
2794 for keeping or rejecting configurations still under development;
2795 default is to assume production environment, and reject configs
2796 still being worked on. Mark Elf configurations (except sparc and
2797 i386) as developmental. Deleted cases matching some generic names
2798 in favor of more specific names. (E.g., when we get Alpha
2799 support, we'll still only support VMS for Vax.)

2802 * config/tc-sparc.c (md_end): Function deleted.
2803 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2813 against placing additional object-file dependent code here. Warn
2814 against contaminating all of GAS with the internals of tc-hppa.c
2815 through inclusion of tc-hppa.h. Delete all forward declarations
2816 for functions only used within tc-hppa.c, likewise for structures,
2817 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2818 conditional code in a few small places.
2820 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2821 structures, global variables, forward declarations together.
2822 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2823 conditional code -- try to group conditional code together
2824 into a few places. Make all functions and variables which
2825 are only used within tc-hppa.c static. PARAMize all functions.
2826 Add comments to functions. Delete unused functions, variables,
2827 #defines, etc. Delete unused members within structures. Delete
2828 ldil;ble hacks -- it is believed they were installed to work
2829 around old gas bugs. Avoid using mixed case for local
2830 functions, variables, and structures. Fix formatting problems
2831 not found by GNU-indent. Add FIXME notices for things which
2832 should be worked on the near future. Delete lots of old
2833 useless (1.36 PA-SOM) code.
2835 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type

3976 * Extensive changes to permit symbols to contain any expression
3977 type and to delay the computation of the expression until the
3978 value is actually needed. This permits setting symbols to values
3979 calculated based on object code size. Expressions were changed to
3980 no longer be in a section, to stop the overloading of segment and
3981 expression type that previously occurred.
3983 * as.c (big_section, pass1_section, diff_section, absent_section):
3985 (expr_section): Added (used for dummy symbols which hold

4094 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
4095 calculating opP->isiz; this permits the expression size to be
4096 determined as well, later on.

5251 dependencies are read, not when they are used).
5253 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
5254 a29k .bss section; the mondfe program doesn't like it.

5303 avoid some redefinition complaints on some systems.
5304 (const, volatile): Don't need these conditionally defined if we
5305 use CONST and VOLATILE from ansidecl.h.
5306 (seg_name): Use CONST, not const.
5308 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5310 * config/tc-mips.c: Reindented to GNU standards.

5314 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5315 (fixup_segment): Add a29k special case; the linker is not prepared
5316 to see a segment offset here.

5321 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5323 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5324 srcdir, might be in objdir.

5343 * Makefile.in (targ-cpu.o): Depend on config.h.
5345 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5347 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5348 dropping a space immediately following an identifier.
5349 * expr.c, write.c: Rewrote assert expressions to not use multiple
5350 lines; I don't think that can be done portably.
5351 * config/tc-mips.c (macro): Use $AT if target register is zero in
5352 load instruction, which it can be for a floating point load.
5354 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5375 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5377 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5378 to be on a single line.
5380 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5426 prototypes for all static functions. Moved existing minimal
5427 debugging format support info #ifndef OBJ_ECOFF blocks.

5430 all callers accordingly.
5431 (tc_get_register): Renamed from get_register, and made non-static.
5433 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5476 * make-gas.com: Find obstack.obj if it's not in the current
5478 * read.c (s_ignore): Don't declare is_end_of_line. It's
5479 redundant, and triggers a VMS gcc compiler bug.
5481 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5482 current segment as an argument. (Ignored in all cases but VMS.)
5483 All callers and definitions changed.

5614 for now; should be machine-dependent.
5616 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
5617 targets, forcing BFD use.

5780 md_relax_table): Use default zero initialization.
5781 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5782 latter, instead of selecting with preprocessor conditionals.
5784 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5786 * configure.in: recognise all sparclite variants

5796 * expr.c (operand): If character other than comma or newline is a
5797 logical end-of-line character, use the newline case.
5798 From Eric Youngdale:
5799 (operand): Set X_add_number field for floating-point numbers.
5800 (operand): Treat zero byte as end-of-operand.
5802 * configure.in (per-target): Look for with_bfd_assembler option.
5803 For now, only accept "no", until the merge is done.
5805 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5806 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5812 * expr.c: Add "const" modifier to hex_value.
5813 * symbols.c: Finish conversion to S_* macros in the VMS only
5814 parts of the program. Add "const" modifier to
5815 md_[long,short]_jump_size. Remove declaration of const_flag
5816 (which will be declared in obj-vms.h).
5817 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5818 Fix arguments to VMS_write_object_file.
5819 * config-gas.com: New file. Script for VMS systems to set up the
5820 configuration to build gas for VMS, and create config.status.
5821 * make-gas.com: Redone to work with new scheme.
5822 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5824 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5825 will swap bytes if needed on a big endian system. Use throughout
5827 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5828 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5829 types of malformed stabs. Change parsing algorithm so that we are
5830 more certain of having all of the information that we need on hand.
5831 * obj-vms.c (final_forward_reference): New function, used to help
5832 resolve the data types of as many struct elements as possible
5833 when some part of the struct is not fully defined by the compiler.

5836 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5837 as symbols as well in the object file. Look for external functions
5838 that start with "__vt.", and turn them into variables, since the
5839 g++ compiler is incapable of doing this.
5840 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5842 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5843 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5844 have the name of the source file yet.
5845 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5847 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5849 * read.c (s_data): Always use "data_section", since it'll map to
5850 SEG_DATA or SEG_E1 if needed.
5851 (s_lcomm): Likewise with bss_section.
5852 (s_fill): Use memset, not bzero.
5854 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5876 (big_section, reg_section, pass1_section, diff_section,
5877 absent_section, text_section, data_section, bss_section): If
5878 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5879 mapping to segT enum values.
5880 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5881 if these are used or defined, if BFD_ASSEMBLER.
5882 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5883 subseg_new split into two functions.
5884 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5886 * as.h (volatile): Don't define if already defined.
5887 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5889 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5890 declare with format attribute for -Wformat checking.
5892 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5894 * app.c, config/tc-*.c: Don't include read.h, since it is already
5897 * These are based on patches from Minh Tran-le
5898 <mtranle@paris.intellicorp.com>.
5899 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5900 obj_format coffbfd and gas_target i386coff for target.
5901 (i[34]86-*-isc*): New host (uses sysv).
5902 * config/i386aix.mt: Removed (no longer used).
5903 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5905 (LDFLAGS): Added, defined as -shlib.
5906 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5907 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5908 (DOT_LABEL_PREFIX): Define.
5909 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5910 name rather than L0\001.
5911 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5913 * symbols.c, symbols.h (local_bss_counter): Removed.
5914 * write.c (write_object_file): bss no longer uses

5922 (size_section): Restored sanity check.
5923 (do_relocs_for): Base section address on s_paddr rather than
5924 computing it. Adjust a29k R_IHIHALF special case to account for
5925 section paddr (used to require paddr to be zero). If there are no
5926 reclos, set s_relptr to 0. Set relocation size in object_headers.
5927 (fill_section): Always set s_vaddr here, removing
5928 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5929 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5930 Set STYP_INFO for .comment.
5931 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5932 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5934 H_{SET,GET}_* macros.
5935 (do_linenos_for): Set lineno size in object_headers.
5936 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5937 set s_vaddr here. If string_byte_count remains 4, set it back to
5938 0, and only write strings out if there are some. Call
5939 fill_section before do_relocs_for and do_linenos_for.
5940 (obj_coff_section): Handle optional quoted second argument giving
5941 section characteristics.
5942 (obj_coff_bss): Added to handle .bss.
5943 (obj_coff_ident): Added to handle .ident (puts string in .comment

5963 (do_scrub_next_char): For \", return " not '.
5964 (symbol_chars): Now const.
5966 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5967 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5969 * config/obj-coff.h: Don't use #elif.
5971 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5972 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5974 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5976 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5998 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5999 using ZERO_BASED_SEGMENTS.
6000 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6001 never set segment address for SEG_E2 (.bss) and don't write out
6002 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6003 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6004 definitions, and don't merge tags with non-tags. Check for .bf
6005 rather than just checking whether the second character is b and
6006 the third character is f.
6007 (obj_coff_val): gcc can generate values which we don't handle
6008 correctly; discard information for now, since it only affects the
6009 debugging information.

6011 (yank_symbols): Don't merge labels.
6012 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6067 options. Updated options documentation for m68k. Some minor
6068 wording/punctuation changes.
6070 Mon Nov 30 11:42:11 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6072 * configure.in: Accept target OS "vms".

6122 xrealloc from xrealloc.c.
6123 * xrealloc.c: Deleted.
6124 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
6126 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
6129 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
6131 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

6150 * all files: Whitespace changes for GNU indentation style, done by
6151 GNU `indent'. Some cleanup still needed, especially of comments.
6153 * configure.in: No te-386bsd.h file exists; don't try to use it.
6155 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
6157 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6158 could be doing emulation.
6160 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6163 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6166 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

6190 consistently const, and always initialized them. Included read.h.
6192 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6194 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6195 constant will not fit in an immediate field.
6196 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6198 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
6200 * obj-coff.c (callj_table): Delete global variable.

6218 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
6220 * version.c: Put conditional "const" before version_string, not

6224 printed rep of null character.
6226 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
6228 * obj-coffbfd.c (write_object_file): check return value of
6231 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6233 * Support for i386-sysv.
6234 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
6235 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
6236 be used to set them all to zero as was done before.

6238 (fill_section): Don't set STYP_NOLOAD for .bss section.
6239 (fixup_segment): 386 uses strange common symbol format.
6240 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
6241 compatibility with SVR3.2 linker.
6242 * configure.in: i386-sysv and i386-sco use coffbfd.
6244 * app.c (do_scrub_next_char): discard whitespace after a label.

6253 fix i960+non-bfd coff bit rot.
6254 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
6255 support for C source listings. (obj_coff_endef): look in the right

6258 * tc-m68k.c (get_num): make it work for all segments, not just the
6261 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6263 * configure.in: recognize i386-*-bsd emulation.

6272 * tc-z8k.c: lots of bug fixes
6274 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6276 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6277 #elif, since it is not supported by old compilers.
6278 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6279 couple of expressions in tc-m68k.c.
6281 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6283 * read.c (cons): If NO_RELOC is defined, use it.
6285 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6287 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6289 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6290 local labels to start with a .) and set REGISTER_PREFIX to %.
6291 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6293 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6304 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6307 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6309 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6310 sections starting from zero, rather than making them consecutive.
6311 This makes subsequent reloc calculations easier, esp if the object
6312 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6313 allocate lcomm in .data rather than in .bss. It seems that some
6314 tools can't cope with a non-zero sized bss before linkage.
6316 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6318 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6319 throughout. That enum no longer means what we thought it meant.

6322 "-mno-688[58]1" options.
6324 * tc-m68k.c: Added CPU32 support.

6333 Change LIBDEPS dependence to LIBS.
6335 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6337 * Makefile.in (install): if $(tooldir) exists, install as in
6340 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6342 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6343 .word is < -32768 or > 32767. The -J flag causes the error to be
6344 ignored. This is to catch over-sized switches generated by gcc on
6345 systems which don't support the broken .word hack.
6346 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6347 write.c (fixup_segment): check for signed .word overflow if
6348 WARN_SIGNED_OVERFLOW_WORD.
6350 * write.c (fixup_segment): fixed missing parens in expression
6351 checking for byte or word overflow.
6353 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6354 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6355 WARN_SIGNED_OVERFLOW_WORD.

6365 * tc-i386.h : new coff defines
6367 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6369 * input-scrub.c (input_scrub_push): call input_file_begin, not
6371 messages.c (as_perror): print ": " between the passed in error and
6372 the strerror, like perror does.
6374 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6376 * Makefile.in: use gas_target instead of modifying target_cpu.
6377 From Steve Chamberlain:
6378 Makefile.in: Handle m68*-*-coff*.
6379 read.c, read.h: add mult argument to s_space
6381 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6382 Motorola and MIT syntax; gas can now assemble either type of
6384 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6385 From Steve Chamberlain:
6386 m68kcoff.mt: for m68k COFF.
6387 obj-coffbfd.c: (fixup_mdeps) added
6388 (size_section) removed bad sanity check

6390 (write_object_file) call fixup_mdeps
6391 (fixup_segment) set fx_subsy to 0.
6392 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6394 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6397 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6399 * Makefile.in (LIBS): Include opcode library.
6401 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
6403 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
6404 including zero are accepted, pass +0.0.

6421 tc-i960.c (md_ri_to_chars): Always output bout object file in
6422 little endian byte order (used to use endianness of host).
6424 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6426 * config/tc-m68k.c (init_table): Now const. Always include 68851
6427 data, so that "bc" is available to 68040 cache instructions.
6428 Added "tt0", "tt1", and 68ec030 variants.
6429 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6430 (enum _register): Added TT0, TT1.
6431 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6432 line number correctly in "internal error" messages. Don't print
6433 architecture-mismatch message for operand errors.
6435 From Colin Smith (colin@wrs.com):
6436 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6437 than install_operand.
6439 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6441 * listing.c (buffer_line): rewind to the start of include
6442 files, they might be included twice.

6446 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
6448 * Makefile.in: defined TARGET_CPU for C code so that it can choose
6449 one element of a family.
6451 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6453 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6454 so that we can assemble hand-written libgcc code.
6456 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6458 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6459 has already been formatted (but may still contain %-characters).
6462 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6464 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6465 written with indirection on the last two operands, which can be
6466 either data or address registers. Added a new operand type 'r'
6467 which accepts either register type. Added '(' to notend stuff in
6468 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6470 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
6472 * as.h (enum _relax_state): Start off at one, not zero, to better

6481 data_last_frag): No longer static.
6482 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
6483 defined, call it. Change segments before calling fixup_segment.
6484 (relax_align): If linkrelax, provide extra padding.
6486 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6487 their not having symbols associated.
6489 * tc-i960.c (norelax, instrument_branches): Default initializer is
6491 (linkrelax): Delete variable definition.
6492 (mem_fmt): Call fix_new with NO_RELOC.

6512 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6514 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
6515 being used with args swapped, causing occasional lossage when
6516 refilling buffers after an include file.
6518 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6520 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6521 version. Discard bogus DONTDEF version.
6522 (as_warn, as_bad, as_fatal): Likewise.
6524 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6526 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6527 selected architecture, print a message saying so and listing what
6528 processors support it, rather than saying "operands mismatch".
6530 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)
6532 * as.h [BROKEN_ASSERT]: If defined, turn off all assertion checks.

6544 * tc-m68k.c: ".align N" means align to N-byte boundary *only*
6545 if TN_SUN3; otherwise align to 2**N-byte bounary.
6547 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6549 * read.c (s_fill): make the .fill size clamped error a warn and
6550 fix bug where 0's were always placed.
6552 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
6553 two bytes of any constant with 0xff:
6555 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6557 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
6558 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

6567 * config/tc-sparc.c (tc_aout_fix_to_chars): If pc-relative, take
6568 fx_offset into account.
6570 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
6572 * configure.in (mips host): Accept "ultrix" with version number.
6574 * expr.c (floating_constant): Separate "=-" to avoid confusing
6575 ancient or broken compilers.
6577 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6578 processor/opcode mismatch, so reword the error message.
6579 (md_assemble): If no CPU has been set (even if FPU/PMMU
6580 characteristics have been), default to 68020. Don't need extra
6581 quotes around error string.
6583 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6585 * read.c (potable): Revert sac's incorrect change made Jul 13.

6665 * write.c (write_object_file): keep the fix_tail clean, which
6666 fixes a bug in -R where relocations were being lost.

6717 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6719 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6720 where gcc looks for it.
6722 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6724 * Makefile.in: Changed some lines to be less confusing for some

6790 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6792 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6794 * expr.c (operand): if can't work out what sort of operand it is,
6795 then look through FLT_CHARS for a hint.
6797 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6799 * Makefile.in, configure.in: removed traces of namesubdir,
6800 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6801 copyrights to '92, changed some from Cygnus to FSF.
6803 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6804 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6805 copyrights to '92, changed some from Cygnus to FSF.
6807 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6809 * expr.c: If an expression is single comma, then return with
6810 SEG_ABSENT rather than an error - since the sparc front end does
6811 really strange things with things like fbge,a
6813 * as.h: include bfd.h if using many sections
6814 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6815 local labels didn't work.
6816 * listing.c (list_symbol_table): don't core dump when there's no
6818 * write.c, write.h: call fix_new with the right number of args on
6820 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6823 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6825 * app.c: MRI compatibility - allow single quote to start a string.
6826 * as.c: fix typo recently introduced.
6827 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6828 * expr.c: Much rewriting, to accomodate MRI syntax for
6829 expressions. Also easier to read now.
6830 * listing.c: Put back defuns
6831 * read.c: modified to accept MRI syntax, put back listing pseudo
6832 ops so that an assembler built with NO_LISTING ignores list ops
6834 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6835 machine is a SPARC or a 29K.
6836 * config/obj-aout.c: added s_sect pseudo op
6837 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6838 fill in the timestamp.
6839 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6840 anymore, define all the relocs which the tc-<x> bit will use so we
6841 can translate from them to the coff types.
6842 * config/tc-a29k.c: reloc_type isn't ane enum any more
6843 * config/tc-m68k.c: Added NO_RELOC definition.
6845 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6847 * Makefile.in: put header files before C source for TAGS; remove
6848 references to non-existent syscalls.h.
6850 * read.c, write.c subsegs.c: back out the .bss changes.
6852 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6854 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6858 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6860 * symbols.c (local_label_name): symbols now start with ^A.
6862 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6863 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6864 generate these sections. .align: will use NOP_OPCODE or 0
6865 for padding. This is just for being nice to the
6868 * expr.c (operand): changed to generate local label "\001L0"
6869 starting with a ^A so that it is recognized as a local label.
6871 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6873 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6874 i/o opcodes - inb, inw, outb and outw. string manipulation with
6875 att syntax - scmp, slod, smov, ssca, ssto.
6877 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6878 to just after .file .
6880 In obj_crawl_symbol_chain() where it tries to put the external
6881 symbols apart, with the condition:
6882 (!S_IS_DEFINED(symbolP) &&
6883 !S_IS_DEBUG(symbolP) &&
6884 !SF_GET_STATICS(symbolP))
6885 it was moving too many symbols out. So I switch it back to the
6887 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6889 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6890 so that we don't use the F_RELFLG which make the linker complain
6891 that somebody has stripped the relocation info.
6893 Also, the AIX ld program require that the relocation table
6894 is sorted by r_vaddr like the standard ATT assembler does.
6896 [he also changed the sizeof(struct ...)'s into the coff
6897 style FOOSZ macros. I'm not sure this is right, but I can't
6898 remember why. xoxorich.]
6900 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6902 * Makefile.in, configure.in, doc: use the doc. Build it, install

6907 * read.c: white space and comments only.
6909 * configure.in: use the new atof-ns32.c for ns32k.
6911 * write.c: comment change only.
6913 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6914 aren't yet integrated.
6916 * tc-i860.[hc]: blew off the dust. Something must still be done
6917 about conflicting relocation types.
6919 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6922 * tc-i960.c, tc-sparc.c: white space and comments only.
6924 * tc-a29k.h: delete duplicate macro definition.
6926 * new file atof-ns32k.c copied from hack's last unreleased gas.
6928 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6930 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6933 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6934 ChangeLog's prior to this are sketchy at best. I have logs.
6935 They just aren't ChangeLogs.
6939 version-control: never
