3 * config/tc-mips.c (mips_ip): Force floating point values to be
6 Fri May 27 10:05:53 1994 Ken Raeburn (raeburn@cygnus.com)
8 Merged in changes from gas-2.3 net release:
10 * Makefile.in (VERSION): Updated to cygnus-2.3.1.
12 * config/obj-vms.c: Replaced unchecked uses of malloc with
15 * listing.c (list_symbol_table): Only test BFD64, not
18 * config/obj-coff.c (fixup_segment) [DIFF_EXPR_OK]: Don't check
19 pcrel, just convert it.
21 * config/obj-vms.c: Removed lots of extra semicolons after
23 (strchr): Don't declare here.
25 * config/ho-vax.h (realloc): Declare.
27 * config/ho-vms.h (strchr, strdup): Declare.

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

282 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
283 Define as macros instead of enumerators, since the Apollo compiler
284 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum

293 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
295 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
296 can be used within a label name.
298 * config/tc-m68k.h (m68k_init_after_args): Declare.

330 all arguments have been processed.

413 directory, and specify PSECT attributes explicitly to linker.
414 Also added missing label.

506 message with reloc type and try to process remainder of file.
508 * doc/Makefile.in (install-info-as, install-info-gasp): New
509 targets, now explicitly checking $(srcdir) for info files.

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

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

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

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

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

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

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

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

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

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

785 (lex_type): Use it for `%'.
787 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
788 (vip_op): Now static, and returns void. Callers changed. Added

2902 * configure.in: Set bfd_gas for all sparc targets. Added facility
2903 for keeping or rejecting configurations still under development;
2904 default is to assume production environment, and reject configs
2905 still being worked on. Mark Elf configurations (except sparc and
2906 i386) as developmental. Deleted cases matching some generic names
2907 in favor of more specific names. (E.g., when we get Alpha

2926 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2927 conditional code in a few small places.

2933 into a few places. Make all functions and variables which
2934 are only used within tc-hppa.c static. PARAMize all functions.
2935 Add comments to functions. Delete unused functions, variables,
2936 #defines, etc. Delete unused members within structures. Delete
2937 ldil;ble hacks -- it is believed they were installed to work
2938 around old gas bugs. Avoid using mixed case for local
2939 functions, variables, and structures. Fix formatting problems
2940 not found by GNU-indent. Add FIXME notices for things which
2941 should be worked on the near future. Delete lots of old

2962 of elf32_symbol_type.
2963 (pa_export_args): Likewise.

2971 a multiple of the section alignment rather than always a
2974 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

3017 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3018 ELF, since the ELF object format does not have these type of
3019 relocations. Change the abort into as as_bad and return
3020 BFD_RELOC_NONE to silence compiler warnings.
3021 (md_assemble): Keep track of the instruction size. Allow white
3022 space between the $ and the constant for compatibility with older

5363 a29k .bss section; the mondfe program doesn't like it.

5384 source directory, if that's not the current directory.
5386 * configure.in (per-host): Accept MIPS host with BSD version

5412 avoid some redefinition complaints on some systems.
5413 (const, volatile): Don't need these conditionally defined if we
5414 use CONST and VOLATILE from ansidecl.h.
5415 (seg_name): Use CONST, not const.
5417 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
5419 * config/tc-mips.c: Reindented to GNU standards.

5423 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
5424 (fixup_segment): Add a29k special case; the linker is not prepared
5425 to see a segment offset here.
5427 * app.c (do_scrub_next_char): Added new state, 10, modifying state

5430 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5432 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5433 srcdir, might be in objdir.

5452 * Makefile.in (targ-cpu.o): Depend on config.h.
5454 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5456 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5457 dropping a space immediately following an identifier.
5458 * expr.c, write.c: Rewrote assert expressions to not use multiple
5459 lines; I don't think that can be done portably.
5460 * config/tc-mips.c (macro): Use $AT if target register is zero in
5461 load instruction, which it can be for a floating point load.
5463 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5484 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5486 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5487 to be on a single line.

5535 prototypes for all static functions. Moved existing minimal
5536 debugging format support info #ifndef OBJ_ECOFF blocks.

5585 * make-gas.com: Find obstack.obj if it's not in the current
5587 * read.c (s_ignore): Don't declare is_end_of_line. It's
5588 redundant, and triggers a VMS gcc compiler bug.
5590 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5591 current segment as an argument. (Ignored in all cases but VMS.)
5592 All callers and definitions changed.

5610 argument to s_ignore. Put "#if 0" around unused code.
5611 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5612 Call elf_xstabs for .stabs and .xstabs operators.
5614 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5616 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
5619 * configure.in: mips-bsd configuration was missing format spec.
5622 * Makefile.in (Makefile): Depends on configure.in.
5624 * config/tc-mips.c (append_insn): Don't check for alignment of
5625 frag in memory; alignment of instructions in section is a separate
5628 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
5631 * listing.h: Always provide function declarations, not macros, so

5889 md_relax_table): Use default zero initialization.
5890 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5891 latter, instead of selecting with preprocessor conditionals.
5893 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

5905 * expr.c (operand): If character other than comma or newline is a
5906 logical end-of-line character, use the newline case.
5907 From Eric Youngdale:
5908 (operand): Set X_add_number field for floating-point numbers.
5909 (operand): Treat zero byte as end-of-operand.
5911 * configure.in (per-target): Look for with_bfd_assembler option.
5912 For now, only accept "no", until the merge is done.
5914 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5915 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5918 parts of the program. Add "const" modifier to hex_value.
5919 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5921 * expr.c: Add "const" modifier to hex_value.
5922 * symbols.c: Finish conversion to S_* macros in the VMS only
5923 parts of the program. Add "const" modifier to
5924 md_[long,short]_jump_size. Remove declaration of const_flag
5925 (which will be declared in obj-vms.h).
5926 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5927 Fix arguments to VMS_write_object_file.
5928 * config-gas.com: New file. Script for VMS systems to set up the
5929 configuration to build gas for VMS, and create config.status.
5930 * make-gas.com: Redone to work with new scheme.
5931 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

5936 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5937 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5938 types of malformed stabs. Change parsing algorithm so that we are
5939 more certain of having all of the information that we need on hand.
5940 * obj-vms.c (final_forward_reference): New function, used to help
5941 resolve the data types of as many struct elements as possible

5945 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5946 as symbols as well in the object file. Look for external functions

5949 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5951 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

5959 SEG_DATA or SEG_E1 if needed.
5960 (s_lcomm): Likewise with bss_section.
5961 (s_fill): Use memset, not bzero.
5963 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5986 absent_section, text_section, data_section, bss_section): If
5987 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5988 mapping to segT enum values.
5989 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5990 if these are used or defined, if BFD_ASSEMBLER.
5991 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5992 subseg_new split into two functions.
5993 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5995 * as.h (volatile): Don't define if already defined.
5996 (had_errors, had_warnings): Provide prototypes for ANSI C even if

6019 name rather than L0\001.
6020 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6022 * symbols.c, symbols.h (local_bss_counter): Removed.
6023 * write.c (write_object_file): bss no longer uses

6031 (size_section): Restored sanity check.
6032 (do_relocs_for): Base section address on s_paddr rather than
6033 computing it. Adjust a29k R_IHIHALF special case to account for

6035 reclos, set s_relptr to 0. Set relocation size in object_headers.
6036 (fill_section): Always set s_vaddr here, removing
6037 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6038 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6039 Set STYP_INFO for .comment.

6043 H_{SET,GET}_* macros.
6044 (do_linenos_for): Set lineno size in object_headers.
6045 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6046 set s_vaddr here. If string_byte_count remains 4, set it back to
6047 0, and only write strings out if there are some. Call
6048 fill_section before do_relocs_for and do_linenos_for.
6049 (obj_coff_section): Handle optional quoted second argument giving
6050 section characteristics.
6051 (obj_coff_bss): Added to handle .bss.

6076 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
6078 * config/obj-coff.h: Don't use #elif.
6080 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
6081 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
6083 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

6095 Sun Dec 13 00:04:38 1992 Ian Lance Taylor (ian@cygnus.com)
6097 * read.c (read_a_source_file): avoid calling xmalloc (0).
6099 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
6101 * listing.c: Call xmalloc, not malloc; don't declare malloc.
6103 * Changes to support SCO 3.2v4:
6104 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
6105 SEG_BSS, fill with NOP_OPCODE.
6106 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
6107 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
6108 using ZERO_BASED_SEGMENTS.
6109 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
6110 never set segment address for SEG_E2 (.bss) and don't write out
6111 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
6112 (obj_coff_endef): Don't merge labels or symbols awaiting forward
6113 definitions, and don't merge tags with non-tags. Check for .bf
6114 rather than just checking whether the second character is b and
6115 the third character is f.
6116 (obj_coff_val): gcc can generate values which we don't handle
6117 correctly; discard information for now, since it only affects the
6118 debugging information.

6120 (yank_symbols): Don't merge labels.
6121 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6123 set segment address if ZERO_BASED_SEGMENTS.
6124 (obj_coff_section): Accept and ignore a trailing quoted string, as
6125 used in AT&T i386 syntax.
6126 (fixup_segment): Take segment as argument. On the i386, adjust PC
6127 relative addends by the segment vaddr.
6128 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
6129 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
6130 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

6231 xrealloc from xrealloc.c.
6232 * xrealloc.c: Deleted.
6233 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
6235 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
6238 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
6240 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

6259 * all files: Whitespace changes for GNU indentation style, done by
6260 GNU `indent'. Some cleanup still needed, especially of comments.
6262 * configure.in: No te-386bsd.h file exists; don't try to use it.
6264 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
6266 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
6267 could be doing emulation.
6269 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6272 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
6275 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
6277 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

6301 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6303 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
6304 constant will not fit in an immediate field.
6305 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
6307 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
6309 * obj-coff.c (callj_table): Delete global variable.

6327 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
6329 * version.c: Put conditional "const" before version_string, not

6340 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
6342 * Support for i386-sysv.
6343 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

6347 (fill_section): Don't set STYP_NOLOAD for .bss section.
6348 (fixup_segment): 386 uses strange common symbol format.

6381 * tc-z8k.c: lots of bug fixes
6383 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6385 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6386 #elif, since it is not supported by old compilers.
6387 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6388 couple of expressions in tc-m68k.c.
6390 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6392 * read.c (cons): If NO_RELOC is defined, use it.
6394 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6396 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6398 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6399 local labels to start with a .) and set REGISTER_PREFIX to %.
6400 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
6402 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
6404 * messages.c: Comment changes.
6406 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

6409 * messages.c: If __STDC__ is not defined, define NO_STDARG.
6411 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
6413 * listing.c (debugging_pseudo): Add stabs and stabn as things to
6416 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
6418 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6419 sections starting from zero, rather than making them consecutive.
6420 This makes subsequent reloc calculations easier, esp if the object
6421 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6422 allocate lcomm in .data rather than in .bss. It seems that some
6423 tools can't cope with a non-zero sized bss before linkage.
6425 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6427 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6428 throughout. That enum no longer means what we thought it meant.

6431 "-mno-688[58]1" options.
6433 * tc-m68k.c: Added CPU32 support.

6441 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
6442 Change LIBDEPS dependence to LIBS.
6444 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
6446 * Makefile.in (install): if $(tooldir) exists, install as in
6449 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6451 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6452 .word is < -32768 or > 32767. The -J flag causes the error to be
6453 ignored. This is to catch over-sized switches generated by gcc on
6454 systems which don't support the broken .word hack.
6455 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6456 write.c (fixup_segment): check for signed .word overflow if
6457 WARN_SIGNED_OVERFLOW_WORD.
6459 * write.c (fixup_segment): fixed missing parens in expression
6460 checking for byte or word overflow.
6462 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
6463 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
6464 WARN_SIGNED_OVERFLOW_WORD.

6472 * obj-coffbfd.h : added stuff
6473 * tc-i386.c (tc_coff_fix2rtype): new function
6474 * tc-i386.h : new coff defines
6476 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6478 * input-scrub.c (input_scrub_push): call input_file_begin, not
6480 messages.c (as_perror): print ": " between the passed in error and
6481 the strerror, like perror does.
6483 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6485 * Makefile.in: use gas_target instead of modifying target_cpu.
6486 From Steve Chamberlain:
6487 Makefile.in: Handle m68*-*-coff*.
6488 read.c, read.h: add mult argument to s_space
6490 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6491 Motorola and MIT syntax; gas can now assemble either type of
6493 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
6494 From Steve Chamberlain:
6495 m68kcoff.mt: for m68k COFF.
6496 obj-coffbfd.c: (fixup_mdeps) added
6497 (size_section) removed bad sanity check
6498 (fill_section) added rs_machine_dependent case
6499 (write_object_file) call fixup_mdeps
6500 (fixup_segment) set fx_subsy to 0.
6501 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6503 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6506 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6508 * Makefile.in (LIBS): Include opcode library.
6510 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
6512 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
6513 including zero are accepted, pass +0.0.

6517 * Makefile.in: map "as" through program_transform_name when
6520 * doc/Makefile.in: map "as" through program_transform_name when
6523 Sat Aug 29 12:11:12 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6525 * Makefile.in (as.new): Depend on LOCAL_LOADLIBES.
6527 Fri Aug 28 16:25:22 1992 Ian Lance Taylor (ian@cygnus.com)

6530 tc-i960.c (md_ri_to_chars): Always output bout object file in
6531 little endian byte order (used to use endianness of host).
6533 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6535 * config/tc-m68k.c (init_table): Now const. Always include 68851
6536 data, so that "bc" is available to 68040 cache instructions.
6537 Added "tt0", "tt1", and 68ec030 variants.
6538 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6539 (enum _register): Added TT0, TT1.
6540 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6541 line number correctly in "internal error" messages. Don't print
6542 architecture-mismatch message for operand errors.
6544 From Colin Smith (colin@wrs.com):
6545 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6546 than install_operand.
6548 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6550 * listing.c (buffer_line): rewind to the start of include
6551 files, they might be included twice.
6553 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
6555 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
6557 * Makefile.in: defined TARGET_CPU for C code so that it can choose
6558 one element of a family.
6560 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6562 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6563 so that we can assemble hand-written libgcc code.
6565 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6567 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6568 has already been formatted (but may still contain %-characters).
6571 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6573 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6574 written with indirection on the last two operands, which can be
6575 either data or address registers. Added a new operand type 'r'

6826 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6828 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6829 where gcc looks for it.
6831 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6833 * Makefile.in: Changed some lines to be less confusing for some

6903 * expr.c (operand): if can't work out what sort of operand it is,
6904 then look through FLT_CHARS for a hint.
6906 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6908 * Makefile.in, configure.in: removed traces of namesubdir,

6912 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6913 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6914 copyrights to '92, changed some from Cygnus to FSF.
6916 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6918 * expr.c: If an expression is single comma, then return with
6919 SEG_ABSENT rather than an error - since the sparc front end does
6920 really strange things with things like fbge,a
6922 * as.h: include bfd.h if using many sections
6923 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6924 local labels didn't work.
6925 * listing.c (list_symbol_table): don't core dump when there's no
6927 * write.c, write.h: call fix_new with the right number of args on

6932 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6934 * app.c: MRI compatibility - allow single quote to start a string.
6935 * as.c: fix typo recently introduced.
6936 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6937 * expr.c: Much rewriting, to accomodate MRI syntax for
6938 expressions. Also easier to read now.
6939 * listing.c: Put back defuns
6940 * read.c: modified to accept MRI syntax, put back listing pseudo
6941 ops so that an assembler built with NO_LISTING ignores list ops
6943 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6944 machine is a SPARC or a 29K.
6945 * config/obj-aout.c: added s_sect pseudo op
6946 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6947 fill in the timestamp.
6948 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6949 anymore, define all the relocs which the tc-<x> bit will use so we
6950 can translate from them to the coff types.
6951 * config/tc-a29k.c: reloc_type isn't ane enum any more
6952 * config/tc-m68k.c: Added NO_RELOC definition.
6954 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6956 * Makefile.in: put header files before C source for TAGS; remove
6957 references to non-existent syscalls.h.
6959 * read.c, write.c subsegs.c: back out the .bss changes.
6961 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6963 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6967 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6969 * symbols.c (local_label_name): symbols now start with ^A.
6971 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6972 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6973 generate these sections. .align: will use NOP_OPCODE or 0
6974 for padding. This is just for being nice to the
6977 * expr.c (operand): changed to generate local label "\001L0"
6978 starting with a ^A so that it is recognized as a local label.
6980 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6982 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6983 i/o opcodes - inb, inw, outb and outw. string manipulation with
6984 att syntax - scmp, slod, smov, ssca, ssto.
6986 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6987 to just after .file .
6989 In obj_crawl_symbol_chain() where it tries to put the external
6990 symbols apart, with the condition:
6991 (!S_IS_DEFINED(symbolP) &&
6992 !S_IS_DEBUG(symbolP) &&
6993 !SF_GET_STATICS(symbolP))
6994 it was moving too many symbols out. So I switch it back to the
6996 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6998 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6999 so that we don't use the F_RELFLG which make the linker complain
7000 that somebody has stripped the relocation info.
7002 Also, the AIX ld program require that the relocation table
7003 is sorted by r_vaddr like the standard ATT assembler does.
7005 [he also changed the sizeof(struct ...)'s into the coff
7006 style FOOSZ macros. I'm not sure this is right, but I can't
7007 remember why. xoxorich.]
7009 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

7018 * configure.in: use the new atof-ns32.c for ns32k.
7020 * write.c: comment change only.
7022 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7023 aren't yet integrated.
7025 * tc-i860.[hc]: blew off the dust. Something must still be done
7026 about conflicting relocation types.
7028 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7031 * tc-i960.c, tc-sparc.c: white space and comments only.
7033 * tc-a29k.h: delete duplicate macro definition.
7035 * new file atof-ns32k.c copied from hack's last unreleased gas.
7037 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7039 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7042 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7043 ChangeLog's prior to this are sketchy at best. I have logs.
7044 They just aren't ChangeLogs.
7048 version-control: never
