3 Merged in changes from gas-2.3 net release:
5 * Makefile.in (VERSION): Updated to cygnus-2.3.1.
7 * config/obj-vms.c: Replaced unchecked uses of malloc with
10 * listing.c (list_symbol_table): Only test BFD64, not
13 * config/obj-coff.c (fixup_segment) [DIFF_EXPR_OK]: Don't check
14 pcrel, just convert it.
16 * config/obj-vms.c: Removed lots of extra semicolons after
18 (strchr): Don't declare here.
20 * config/ho-vax.h (realloc): Declare.
22 * config/ho-vms.h (strchr, strdup): Declare.
24 * config/tc-sparc.c (md_parse_option) [OBJ_ELF]: Accept and ignore

29 * config/obj-vms.h (DBG_S_C_SQUAD, DBG_S_C_UQUAD): define these
30 new VMS symbol-type macros; signed and unsigned quadword integers,
31 for `long long' support. Their values come from the existing
32 DSC$K_DTYPE_QU and DSC$K_DTYPE_Q macros in <descrip.h>. The
33 VMS debugger now recognizes `long long' variables correctly.
34 config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
35 for gcc2's predefined types "long double" (same as double, as
36 per gcc's current state), "long long int", "long long unsigned
37 int", and final `otherwise' case (to avoid uninitialized type
38 and size fields). [caveat: predefined types "complex int",
39 "complex float", "complex double", and "complex long double" are
42 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
43 of 0, because the latter indicates success rather than failure
44 when passed to `exit' or return from `main' compiled by gcc2.
46 * config/obj-vms.c (array_suffix, generate_suffix): replace two
47 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.
48 (VMS_typedef_parse): eliminate redundant if-then-else when
49 allocating new symbol entry and linking it to VMS_Symbol_type_list.
51 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
53 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret
54 the contents of the GAS_VERSION string when falling back to it for
55 language processor identification.
57 * make-gas.com, vmsconf.sh (ENVIRON): fix misspelling of
58 `psect_attr' in linker options.

288 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
290 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
291 can be used within a label name.

499 don't spew remainder of input file in error message.
500 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
501 message with reloc type and try to process remainder of file.

513 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
514 flag rather than signedp field. Only permit extended range if
515 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
516 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
518 * config/tc-ppc.c (ppc_size): New static variable.
519 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
520 (md_begin): If an instruction has a size specific flag set, only
521 add it if we are assembling that size.
523 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
525 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get

541 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
542 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
543 and -many (all architectures).

554 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
556 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
557 branch with an instruction that uses $at, in case the branch is
559 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
560 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
561 to make it pcrel_offset.
562 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
563 reloc->address; another gruesome hack to get gas reloc handling to
566 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
568 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

572 (md_assemble): Call it.
573 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
575 (lituse_pending): New variable. Set by anything that generates a
576 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
577 tested by code that might want to emit a LITUSE reloc.
578 (emit_unaligned_io): New function. Currently calls md_assemble,
579 but it should eventually be converted to generate the insn itself
580 and call emit_insn directly.
581 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
582 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
583 emit_bis_r): Likewise.

590 the value can't be resolved.
592 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
594 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
595 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

608 * config/tc-mips.c (enum mips_pic_level): New enum.
609 (mips_pic): Change from int to enum mips_pic_level. Change all
610 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
611 (load_address): Handle EMBEDDED_PIC.
612 (macro): Handle EMBEDDED_PIC in all PIC cases.
613 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
614 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
615 -non_shared to use NO_PIC (this is how the Irix 5 assembler
616 works). Do not permit -G with SVR4_PIC.
617 (s_abicalls): Warn if -G was used, and force -G 0.
618 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
619 anything but a.out, not just for ELF. For ECOFF, don't generate a
620 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
622 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
624 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

630 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
632 * Makefile.in (config-stamp): If `defs' is defined, emit a
633 preprocessor directive to create a macro named by this value into
634 config.new; don't explicitly go for BFD_ASSEMBLER.
635 * configure.in: Define `defs', not `BFDDEF'. Set it to
636 MANY_SEGMENTS for any obj-coffbfd target.
637 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
638 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
640 (LOCAL_LOADLIBES): Deleted.
641 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
642 * config/m88kcoff.mt (TDEFINES): Ditto.

668 bfd_set_symtab is called.
669 (dump_section_relocs): Note whether a symbol is a section symbol
671 (adjust_reloc_syms): For now, always supply an absolute symbol for
672 fixups without symbols but not yet `done'. Use section_symbol to
673 get the symbol, instead of going directly for abs_symbol.
674 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
675 reloc is not a section symbol and is not in the symbol table.
676 (set_symtab): New function, broken out from write_object_file.
677 Counts symbol table instead of relying on an earlier count.
678 (write_object_file): Call set_symtab, but do it after potentially
679 invoking the *_frob_file macros. Don't bother counting symbols.
680 Call symbol_remove, instead of expanding it in place. Moved the
681 conditionalized `object_file_size' declaration down to
682 conditionalized block where it's used. When using the absolute
683 symbol for a fixup without a symbol, set sy_used_in_reloc.
684 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
685 the correct symbol for the absolute section.
687 * subsegs.c (section_symbol): Use symbol_new instead of
688 symbol_make, since we may want it to go into the symbol table.
689 Make the new symbol have internal linkage. If
690 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
691 symbol with the newly created GAS symbol.
692 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
693 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

698 (in_signed_range): New function.
700 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
701 (sparc_ip, label "immediate"): Reject constants for pcrel
702 instructions only if the relocation type indicates a "call"
703 instruction and the offset is within range of a "jmpl %g0". If
704 it's not in range, use the absolute section symbol plus an offset.
705 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
707 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
709 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
712 * configure.in: Eliminated all targets using obj-coff but not
713 defining BFD_ASSEMBLER; I think all such targets that are
714 supported will be matched by real CPU-OS combinations earlier in
716 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
717 some comments about the dpx2 configuration, but left it disabled,
718 since it couldn't be reached before.
719 (target a29k-amd-ebmonold): Deleted.
721 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

729 the 'j' operand if there are no further alternatives for this
732 * config/obj-coffbfd.c (adjust_stab_section): Initialize
733 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
734 is not SEG_UNKNOWN rather than checking whether it is >= 0.
736 * config/tc-mips.c (mips_align): Take new argument, label, and use
737 it instead of global insn_label.
738 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
739 call to mips_emit_delay and pass it to mips_align.
741 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
743 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
745 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
746 argument to a .callinfo directive. Don't loop forever on errors.
748 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
749 use pre-defined registers as arguments.
751 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
753 * write.c (write_object_file): Check both S_IS_LOCAL and
754 S_IS_EXTERNAL when deciding whether to discard a symbol.
756 * config-gas.com: Scan Makefile.in, not version.c, for current
757 version number. Delete all versions of temp files when finished
758 with them. Create config.h.
760 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
761 values to reduce number of lookups with S_GET_VALUE. Skip debug
762 symbols to avoid "a really nasty bug". (From Holger Teutsch,
763 holger@botbso.rhein-main.de.)
764 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
765 field. (Also from Holger Teutsch.) Watch for a would-be register
766 mask that spans frags.
768 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
769 this_base, not line_base. (Patch from Andreas Arens,
770 ari@obelix.av.rwth-aachen.de.)
772 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
773 look local if they're exported or undefined. Used to be done for
776 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
777 Get it from the looked-up symbol, instead of using the string from
778 the input stream, which is no longer null-terminated.

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

2897 * configure.in: Set bfd_gas for all sparc targets. Added facility
2898 for keeping or rejecting configurations still under development;
2899 default is to assume production environment, and reject configs
2900 still being worked on. Mark Elf configurations (except sparc and
2901 i386) as developmental. Deleted cases matching some generic names
2902 in favor of more specific names. (E.g., when we get Alpha

2920 for functions only used within tc-hppa.c, likewise for structures,
2921 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2922 conditional code in a few small places.
2924 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2925 structures, global variables, forward declarations together.

2928 into a few places. Make all functions and variables which
2929 are only used within tc-hppa.c static. PARAMize all functions.
2930 Add comments to functions. Delete unused functions, variables,
2931 #defines, etc. Delete unused members within structures. Delete
2932 ldil;ble hacks -- it is believed they were installed to work
2933 around old gas bugs. Avoid using mixed case for local
2934 functions, variables, and structures. Fix formatting problems
2935 not found by GNU-indent. Add FIXME notices for things which
2936 should be worked on the near future. Delete lots of old

2954 * config/tc-hppa.c: Likewise.
2956 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2957 of elf32_symbol_type.
2958 (pa_export_args): Likewise.
2959 (elf_hppa_final_processing): Likewise.

3010 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3012 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3013 ELF, since the ELF object format does not have these type of
3014 relocations. Change the abort into as as_bad and return
3015 BFD_RELOC_NONE to silence compiler warnings.
3016 (md_assemble): Keep track of the instruction size. Allow white
3017 space between the $ and the constant for compatibility with older
3018 gases and other assemblers.

5407 avoid some redefinition complaints on some systems.
5408 (const, volatile): Don't need these conditionally defined if we
5409 use CONST and VOLATILE from ansidecl.h.
5410 (seg_name): Use CONST, not const.

5418 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5419 (fixup_segment): Add a29k special case; the linker is not prepared
5420 to see a segment offset here.

5425 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5427 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5428 srcdir, might be in objdir.

5447 * Makefile.in (targ-cpu.o): Depend on config.h.
5449 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5451 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5452 dropping a space immediately following an identifier.
5453 * expr.c, write.c: Rewrote assert expressions to not use multiple
5454 lines; I don't think that can be done portably.
5455 * config/tc-mips.c (macro): Use $AT if target register is zero in
5456 load instruction, which it can be for a floating point load.
5458 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5479 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5481 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5482 to be on a single line.

5530 prototypes for all static functions. Moved existing minimal
5531 debugging format support info #ifndef OBJ_ECOFF blocks.

5580 * make-gas.com: Find obstack.obj if it's not in the current
5582 * read.c (s_ignore): Don't declare is_end_of_line. It's
5583 redundant, and triggers a VMS gcc compiler bug.
5585 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5586 current segment as an argument. (Ignored in all cases but VMS.)
5587 All callers and definitions changed.

5884 md_relax_table): Use default zero initialization.
5885 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

5900 * expr.c (operand): If character other than comma or newline is a
5901 logical end-of-line character, use the newline case.

5903 (operand): Set X_add_number field for floating-point numbers.
5904 (operand): Treat zero byte as end-of-operand.
5906 * configure.in (per-target): Look for with_bfd_assembler option.
5907 For now, only accept "no", until the merge is done.
5909 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5910 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5919 md_[long,short]_jump_size. Remove declaration of const_flag
5920 (which will be declared in obj-vms.h).
5921 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5922 Fix arguments to VMS_write_object_file.
5923 * config-gas.com: New file. Script for VMS systems to set up the

5931 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5932 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5933 types of malformed stabs. Change parsing algorithm so that we are
5934 more certain of having all of the information that we need on hand.
5935 * obj-vms.c (final_forward_reference): New function, used to help
5936 resolve the data types of as many struct elements as possible

5940 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5941 as symbols as well in the object file. Look for external functions

5944 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5946 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

5954 SEG_DATA or SEG_E1 if needed.
5955 (s_lcomm): Likewise with bss_section.
5956 (s_fill): Use memset, not bzero.

5983 mapping to segT enum values.
5984 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5985 if these are used or defined, if BFD_ASSEMBLER.
5986 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5987 subseg_new split into two functions.
5988 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5990 * as.h (volatile): Don't define if already defined.
5991 (had_errors, had_warnings): Provide prototypes for ANSI C even if

6011 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6012 (DOT_LABEL_PREFIX): Define.

6014 name rather than L0\001.
6015 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6017 * symbols.c, symbols.h (local_bss_counter): Removed.
6018 * write.c (write_object_file): bss no longer uses

6026 (size_section): Restored sanity check.
6027 (do_relocs_for): Base section address on s_paddr rather than
6028 computing it. Adjust a29k R_IHIHALF special case to account for

6030 reclos, set s_relptr to 0. Set relocation size in object_headers.
6031 (fill_section): Always set s_vaddr here, removing
6032 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6033 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6034 Set STYP_INFO for .comment.

6038 H_{SET,GET}_* macros.
6039 (do_linenos_for): Set lineno size in object_headers.
6040 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6041 set s_vaddr here. If string_byte_count remains 4, set it back to
6042 0, and only write strings out if there are some. Call
6043 fill_section before do_relocs_for and do_linenos_for.
6044 (obj_coff_section): Handle optional quoted second argument giving
6045 section characteristics.
6046 (obj_coff_bss): Added to handle .bss.
6047 (obj_coff_ident): Added to handle .ident (puts string in .comment

6073 * config/obj-coff.h: Don't use #elif.
6075 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6076 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

6094 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
6096 * listing.c: Call xmalloc, not malloc; don't declare malloc.
6098 * Changes to support SCO 3.2v4:
6099 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
6100 SEG_BSS, fill with NOP_OPCODE.
6101 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6102 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6103 using ZERO_BASED_SEGMENTS.

6105 never set segment address for SEG_E2 (.bss) and don't write out
6106 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6107 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6108 definitions, and don't merge tags with non-tags. Check for .bf
6109 rather than just checking whether the second character is b and
6110 the third character is f.
6111 (obj_coff_val): gcc can generate values which we don't handle
6112 correctly; discard information for now, since it only affects the
6113 debugging information.

6115 (yank_symbols): Don't merge labels.
6116 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6118 set segment address if ZERO_BASED_SEGMENTS.
6119 (obj_coff_section): Accept and ignore a trailing quoted string, as
6120 used in AT&T i386 syntax.

6122 relative addends by the segment vaddr.
6123 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6124 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
6125 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

6228 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
6230 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
6233 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
6235 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

6254 * all files: Whitespace changes for GNU indentation style, done by
6255 GNU `indent'. Some cleanup still needed, especially of comments.

6261 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6262 could be doing emulation.
6264 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6267 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6270 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
6272 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

6296 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6298 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6299 constant will not fit in an immediate field.
6300 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

6335 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6337 * Support for i386-sysv.
6338 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6357 fix i960+non-bfd coff bit rot.
6358 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
6359 support for C source listings. (obj_coff_endef): look in the right

6376 * tc-z8k.c: lots of bug fixes
6378 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6380 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6381 #elif, since it is not supported by old compilers.
6382 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6383 couple of expressions in tc-m68k.c.
6385 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6387 * read.c (cons): If NO_RELOC is defined, use it.
6389 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6391 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6393 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6394 local labels to start with a .) and set REGISTER_PREFIX to %.
6395 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6397 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

6404 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6406 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6408 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6411 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6413 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6414 sections starting from zero, rather than making them consecutive.
6415 This makes subsequent reloc calculations easier, esp if the object
6416 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6417 allocate lcomm in .data rather than in .bss. It seems that some
6418 tools can't cope with a non-zero sized bss before linkage.
6420 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6422 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6423 throughout. That enum no longer means what we thought it meant.

6426 "-mno-688[58]1" options.
6428 * tc-m68k.c: Added CPU32 support.

6436 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6437 Change LIBDEPS dependence to LIBS.
6439 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6441 * Makefile.in (install): if $(tooldir) exists, install as in
6444 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6446 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6447 .word is < -32768 or > 32767. The -J flag causes the error to be
6448 ignored. This is to catch over-sized switches generated by gcc on
6449 systems which don't support the broken .word hack.
6450 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6451 write.c (fixup_segment): check for signed .word overflow if
6452 WARN_SIGNED_OVERFLOW_WORD.
6454 * write.c (fixup_segment): fixed missing parens in expression
6455 checking for byte or word overflow.
6457 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6458 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6459 WARN_SIGNED_OVERFLOW_WORD.

6467 * obj-coffbfd.h : added stuff
6468 * tc-i386.c (tc_coff_fix2rtype): new function
6469 * tc-i386.h : new coff defines
6471 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6473 * input-scrub.c (input_scrub_push): call input_file_begin, not
6475 messages.c (as_perror): print ": " between the passed in error and
6476 the strerror, like perror does.
6478 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6480 * Makefile.in: use gas_target instead of modifying target_cpu.
6481 From Steve Chamberlain:
6482 Makefile.in: Handle m68*-*-coff*.
6483 read.c, read.h: add mult argument to s_space
6485 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6486 Motorola and MIT syntax; gas can now assemble either type of
6488 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6489 From Steve Chamberlain:
6490 m68kcoff.mt: for m68k COFF.
6491 obj-coffbfd.c: (fixup_mdeps) added

6493 (fill_section) added rs_machine_dependent case
6494 (write_object_file) call fixup_mdeps
6495 (fixup_segment) set fx_subsy to 0.
6496 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6498 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6501 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6503 * Makefile.in (LIBS): Include opcode library.
6505 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
6507 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

6525 tc-i960.c (md_ri_to_chars): Always output bout object file in
6526 little endian byte order (used to use endianness of host).
6528 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6530 * config/tc-m68k.c (init_table): Now const. Always include 68851
6531 data, so that "bc" is available to 68040 cache instructions.
6532 Added "tt0", "tt1", and 68ec030 variants.
6533 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6534 (enum _register): Added TT0, TT1.
6535 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6536 line number correctly in "internal error" messages. Don't print
6537 architecture-mismatch message for operand errors.
6539 From Colin Smith (colin@wrs.com):
6540 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6541 than install_operand.
6543 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6545 * listing.c (buffer_line): rewind to the start of include
6546 files, they might be included twice.
6548 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
6550 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
6552 * Makefile.in: defined TARGET_CPU for C code so that it can choose
6553 one element of a family.
6555 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6557 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6558 so that we can assemble hand-written libgcc code.
6560 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6562 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6563 has already been formatted (but may still contain %-characters).
6566 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6568 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6569 written with indirection on the last two operands, which can be
6570 either data or address registers. Added a new operand type 'r'
6571 which accepts either register type. Added '(' to notend stuff in
6572 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6574 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
6576 * as.h (enum _relax_state): Start off at one, not zero, to better
6577 catch uninitialized-variable errors.

6821 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6823 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6824 where gcc looks for it.
6826 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6828 * Makefile.in: Changed some lines to be less confusing for some

6901 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6903 * Makefile.in, configure.in: removed traces of namesubdir,

6907 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6908 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6909 copyrights to '92, changed some from Cygnus to FSF.
6911 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6913 * expr.c: If an expression is single comma, then return with
6914 SEG_ABSENT rather than an error - since the sparc front end does
6915 really strange things with things like fbge,a
6917 * as.h: include bfd.h if using many sections
6918 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6919 local labels didn't work.
6920 * listing.c (list_symbol_table): don't core dump when there's no
6922 * write.c, write.h: call fix_new with the right number of args on
6924 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6927 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6929 * app.c: MRI compatibility - allow single quote to start a string.
6930 * as.c: fix typo recently introduced.
6931 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6932 * expr.c: Much rewriting, to accomodate MRI syntax for
6933 expressions. Also easier to read now.
6934 * listing.c: Put back defuns
6935 * read.c: modified to accept MRI syntax, put back listing pseudo
6936 ops so that an assembler built with NO_LISTING ignores list ops
6938 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6939 machine is a SPARC or a 29K.
6940 * config/obj-aout.c: added s_sect pseudo op
6941 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6942 fill in the timestamp.
6943 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6944 anymore, define all the relocs which the tc-<x> bit will use so we
6945 can translate from them to the coff types.
6946 * config/tc-a29k.c: reloc_type isn't ane enum any more
6947 * config/tc-m68k.c: Added NO_RELOC definition.
6949 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6951 * Makefile.in: put header files before C source for TAGS; remove
6952 references to non-existent syscalls.h.
6954 * read.c, write.c subsegs.c: back out the .bss changes.
6956 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6958 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6962 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6964 * symbols.c (local_label_name): symbols now start with ^A.
6966 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6967 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6968 generate these sections. .align: will use NOP_OPCODE or 0
6969 for padding. This is just for being nice to the
6972 * expr.c (operand): changed to generate local label "\001L0"
6973 starting with a ^A so that it is recognized as a local label.
6975 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6977 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6978 i/o opcodes - inb, inw, outb and outw. string manipulation with
6979 att syntax - scmp, slod, smov, ssca, ssto.
6981 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6982 to just after .file .
6984 In obj_crawl_symbol_chain() where it tries to put the external
6985 symbols apart, with the condition:
6986 (!S_IS_DEFINED(symbolP) &&
6987 !S_IS_DEBUG(symbolP) &&
6988 !SF_GET_STATICS(symbolP))
6989 it was moving too many symbols out. So I switch it back to the
6991 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6993 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6994 so that we don't use the F_RELFLG which make the linker complain
6995 that somebody has stripped the relocation info.
6997 Also, the AIX ld program require that the relocation table
6998 is sorted by r_vaddr like the standard ATT assembler does.
7000 [he also changed the sizeof(struct ...)'s into the coff
7001 style FOOSZ macros. I'm not sure this is right, but I can't
7002 remember why. xoxorich.]
7004 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
7006 * Makefile.in, configure.in, doc: use the doc. Build it, install

7013 * configure.in: use the new atof-ns32.c for ns32k.
7015 * write.c: comment change only.
7017 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7018 aren't yet integrated.
7020 * tc-i860.[hc]: blew off the dust. Something must still be done
7021 about conflicting relocation types.
7023 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7026 * tc-i960.c, tc-sparc.c: white space and comments only.
7028 * tc-a29k.h: delete duplicate macro definition.
7030 * new file atof-ns32k.c copied from hack's last unreleased gas.
7032 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7034 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7037 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7038 ChangeLog's prior to this are sketchy at best. I have logs.
7039 They just aren't ChangeLogs.
7043 version-control: never
