119 (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
120 rather than hard coded constants.
121 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

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

453 still being worked on. Mark Elf configurations (except sparc and
454 i386) as developmental. Deleted cases matching some generic names
455 in favor of more specific names. (E.g., when we get Alpha
456 support, we'll still only support VMS for Vax.)

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

470 against placing additional object-file dependent code here. Warn
471 against contaminating all of GAS with the internals of tc-hppa.c
472 through inclusion of tc-hppa.h. Delete all forward declarations
473 for functions only used within tc-hppa.c, likewise for structures,
474 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
475 conditional code in a few small places.
477 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
478 structures, global variables, forward declarations together.
479 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
480 conditional code -- try to group conditional code together
481 into a few places. Make all functions and variables which
482 are only used within tc-hppa.c static. PARAMize all functions.
483 Add comments to functions. Delete unused functions, variables,
484 #defines, etc. Delete unused members within structures. Delete
485 ldil;ble hacks -- it is believed they were installed to work
486 around old gas bugs. Avoid using mixed case for local
487 functions, variables, and structures. Fix formatting problems
488 not found by GNU-indent. Add FIXME notices for things which
489 should be worked on the near future. Delete lots of old
490 useless (1.36 PA-SOM) code.
492 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
493 field of the fixS structure. Needed to build unwind
494 descriptors correctly.

1633 * Extensive changes to permit symbols to contain any expression
1634 type and to delay the computation of the expression until the
1635 value is actually needed. This permits setting symbols to values
1636 calculated based on object code size. Expressions were changed to
1637 no longer be in a section, to stop the overloading of segment and
1638 expression type that previously occurred.
1640 * as.c (big_section, pass1_section, diff_section, absent_section):
1642 (expr_section): Added (used for dummy symbols which hold

1726 (previous_section, previous_subsection): New vars.
1727 (obj_elf_section): Save current place in case DWARF code wants us
1728 to pop back to it. Handle unquoted section name as well as quoted
1729 section name. Don't crash on invalid strings.
1730 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

1751 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
1752 calculating opP->isiz; this permits the expression size to be
1753 determined as well, later on.

1839 * Removed sy_forward and replaced it with an undefined expression
1840 as the value of a symbol.
1841 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
1842 sy_resolved and sy_resolving single bit fields.
1843 * symbols.c (symbol_new): Don't initialize sy_forward field.
1844 (resolve_symbol_value): New function to adjust symbol value by
1845 fragment address, using recursion to resolve forward symbols.

1847 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
1848 expression rather than setting symbolP->sy_forward.
1849 * write.c (write_object_file): Use resolve_symbol_value on
1850 symbols, keeping the common case (the old behaviour) inline.
1851 * config/obj-aout.c (obj_aout_frob_symbol): Removed sy_forward
1852 handling (subsumed by write.c change).
1853 * config/obj-coff.c, config/obj-coffbfd.c (obj_coff_val): Set

2846 than ECOFF line number information.
2847 (obj_ecoff_stab): Accept non-zero values for stabs line number.

2879 * doc/as.texinfo: First pass at using new texinfo features --
2880 variables, conditional tests. Far from complete.

2908 dependencies are read, not when they are used).
2910 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
2911 a29k .bss section; the mondfe program doesn't like it.

2956 process relocs if there aren't any relocs to process. Avoids
2957 malloc/free bug on SCO too.

2960 avoid some redefinition complaints on some systems.
2961 (const, volatile): Don't need these conditionally defined if we
2962 use CONST and VOLATILE from ansidecl.h.
2963 (seg_name): Use CONST, not const.
2965 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
2967 * config/tc-mips.c: Reindented to GNU standards.

2971 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
2972 (fixup_segment): Add a29k special case; the linker is not prepared
2973 to see a segment offset here.

2978 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2980 * Makefile.in: add dvi target; as-$(config).texinfo might live in

2996 bignums, but don't emit error message.
2998 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3000 * Makefile.in (targ-cpu.o): Depend on config.h.
3002 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3004 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3005 dropping a space immediately following an identifier.
3006 * expr.c, write.c: Rewrote assert expressions to not use multiple
3007 lines; I don't think that can be done portably.
3008 * config/tc-mips.c (macro): Use $AT if target register is zero in
3009 load instruction, which it can be for a floating point load.
3011 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3032 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3034 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3035 to be on a single line.

3083 prototypes for all static functions. Moved existing minimal
3084 debugging format support info #ifndef OBJ_ECOFF blocks.

3086 does not support a non sign extended high 16 bits reloc. Adjusted
3087 all callers accordingly.
3088 (tc_get_register): Renamed from get_register, and made non-static.
3090 * config/mips-big.mt, config/mips-lit.mt: New files. Define

3133 * make-gas.com: Find obstack.obj if it's not in the current
3135 * read.c (s_ignore): Don't declare is_end_of_line. It's
3136 redundant, and triggers a VMS gcc compiler bug.
3138 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3139 current segment as an argument. (Ignored in all cases but VMS.)
3140 All callers and definitions changed.

3437 md_relax_table): Use default zero initialization.
3438 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3439 latter, instead of selecting with preprocessor conditionals.
3441 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3443 * configure.in: recognise all sparclite variants

3451 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3453 * expr.c (operand): If character other than comma or newline is a
3454 logical end-of-line character, use the newline case.
3455 From Eric Youngdale:
3456 (operand): Set X_add_number field for floating-point numbers.
3457 (operand): Treat zero byte as end-of-operand.
3459 * configure.in (per-target): Look for with_bfd_assembler option.
3460 For now, only accept "no", until the merge is done.
3462 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3463 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3469 * expr.c: Add "const" modifier to hex_value.
3470 * symbols.c: Finish conversion to S_* macros in the VMS only
3471 parts of the program. Add "const" modifier to
3472 md_[long,short]_jump_size. Remove declaration of const_flag
3473 (which will be declared in obj-vms.h).
3474 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3475 Fix arguments to VMS_write_object_file.
3476 * config-gas.com: New file. Script for VMS systems to set up the
3477 configuration to build gas for VMS, and create config.status.
3478 * make-gas.com: Redone to work with new scheme.
3479 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3481 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3482 will swap bytes if needed on a big endian system. Use throughout
3484 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3485 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3486 types of malformed stabs. Change parsing algorithm so that we are
3487 more certain of having all of the information that we need on hand.
3488 * obj-vms.c (final_forward_reference): New function, used to help
3489 resolve the data types of as many struct elements as possible
3490 when some part of the struct is not fully defined by the compiler.

3493 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3494 as symbols as well in the object file. Look for external functions
3495 that start with "__vt.", and turn them into variables, since the
3496 g++ compiler is incapable of doing this.
3497 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3499 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3500 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3501 have the name of the source file yet.
3502 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3504 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3506 * read.c (s_data): Always use "data_section", since it'll map to
3507 SEG_DATA or SEG_E1 if needed.
3508 (s_lcomm): Likewise with bss_section.
3509 (s_fill): Use memset, not bzero.
3511 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3532 (section_alignment): Declare only if not BFD_ASSEMBLER.
3533 (big_section, reg_section, pass1_section, diff_section,
3534 absent_section, text_section, data_section, bss_section): If
3535 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3536 mapping to segT enum values.
3537 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3538 if these are used or defined, if BFD_ASSEMBLER.
3539 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3540 subseg_new split into two functions.
3541 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3543 * as.h (volatile): Don't define if already defined.
3544 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3546 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3547 declare with format attribute for -Wformat checking.
3549 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3551 * app.c, config/tc-*.c: Don't include read.h, since it is already
3554 * These are based on patches from Minh Tran-le
3555 <mtranle@paris.intellicorp.com>.
3556 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3557 obj_format coffbfd and gas_target i386coff for target.
3558 (i[34]86-*-isc*): New host (uses sysv).
3559 * config/i386aix.mt: Removed (no longer used).
3560 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3562 (LDFLAGS): Added, defined as -shlib.
3563 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3564 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3565 (DOT_LABEL_PREFIX): Define.
3566 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3567 name rather than L0\001.
3568 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3570 * symbols.c, symbols.h (local_bss_counter): Removed.
3571 * write.c (write_object_file): bss no longer uses
3572 local_bss_counter. Pass correct data and bss size to
3573 VMS_write_object_file.

3579 (size_section): Restored sanity check.
3580 (do_relocs_for): Base section address on s_paddr rather than
3581 computing it. Adjust a29k R_IHIHALF special case to account for
3582 section paddr (used to require paddr to be zero). If there are no
3583 reclos, set s_relptr to 0. Set relocation size in object_headers.
3584 (fill_section): Always set s_vaddr here, removing
3585 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3586 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3587 Set STYP_INFO for .comment.
3588 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3589 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3591 H_{SET,GET}_* macros.
3592 (do_linenos_for): Set lineno size in object_headers.
3593 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3594 set s_vaddr here. If string_byte_count remains 4, set it back to
3595 0, and only write strings out if there are some. Call
3596 fill_section before do_relocs_for and do_linenos_for.
3597 (obj_coff_section): Handle optional quoted second argument giving
3598 section characteristics.
3599 (obj_coff_bss): Added to handle .bss.
3600 (obj_coff_ident): Added to handle .ident (puts string in .comment

3620 (do_scrub_next_char): For \", return " not '.
3621 (symbol_chars): Now const.
3623 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3624 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3626 * config/obj-coff.h: Don't use #elif.
3628 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3629 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3631 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
3633 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

3655 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3656 using ZERO_BASED_SEGMENTS.
3657 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3658 never set segment address for SEG_E2 (.bss) and don't write out
3659 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3660 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3661 definitions, and don't merge tags with non-tags. Check for .bf
3662 rather than just checking whether the second character is b and
3663 the third character is f.
3664 (obj_coff_val): gcc can generate values which we don't handle
3665 correctly; discard information for now, since it only affects the
3666 debugging information.
3667 (tag_find_or_name): Don't insert tags in the symbol table.
3668 (yank_symbols): Don't merge labels.
3669 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3807 * all files: Whitespace changes for GNU indentation style, done by
3808 GNU `indent'. Some cleanup still needed, especially of comments.
3810 * configure.in: No te-386bsd.h file exists; don't try to use it.
3812 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
3814 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
3815 could be doing emulation.
3817 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3820 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

3847 consistently const, and always initialized them. Included read.h.
3849 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
3851 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
3852 constant will not fit in an immediate field.
3853 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
3855 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
3857 * obj-coff.c (callj_table): Delete global variable.

3872 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
3873 so widening works consistently.
3875 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
3877 * version.c: Put conditional "const" before version_string, not
3878 before dummy function for VMS. Now version 1.91.03.
3880 * app.c (do_scrub_next_char): Need double-\ before `000' to show
3881 printed rep of null character.
3883 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
3885 * obj-coffbfd.c (write_object_file): check return value of
3888 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3890 * Support for i386-sysv.
3891 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
3892 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
3893 be used to set them all to zero as was done before.
3894 (fill_section): segment addresses now set in write_object_file.
3895 (fill_section): Don't set STYP_NOLOAD for .bss section.
3896 (fixup_segment): 386 uses strange common symbol format.
3897 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
3898 compatibility with SVR3.2 linker.
3899 * configure.in: i386-sysv and i386-sco use coffbfd.
3901 * app.c (do_scrub_next_char): discard whitespace after a label.

3915 * tc-m68k.c (get_num): make it work for all segments, not just the
3918 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

3929 * tc-z8k.c: lots of bug fixes
3931 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3933 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3934 #elif, since it is not supported by old compilers.
3935 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3936 couple of expressions in tc-m68k.c.
3938 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3940 * read.c (cons): If NO_RELOC is defined, use it.
3942 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3944 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3946 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3947 local labels to start with a .) and set REGISTER_PREFIX to %.
3948 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3950 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

3964 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
3966 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3967 sections starting from zero, rather than making them consecutive.
3968 This makes subsequent reloc calculations easier, esp if the object
3969 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3970 allocate lcomm in .data rather than in .bss. It seems that some
3971 tools can't cope with a non-zero sized bss before linkage.
3973 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3975 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3976 throughout. That enum no longer means what we thought it meant.

3992 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
3994 * Makefile.in (install): if $(tooldir) exists, install as in
3997 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3999 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4000 .word is < -32768 or > 32767. The -J flag causes the error to be
4001 ignored. This is to catch over-sized switches generated by gcc on
4002 systems which don't support the broken .word hack.
4003 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4004 write.c (fixup_segment): check for signed .word overflow if
4005 WARN_SIGNED_OVERFLOW_WORD.
4007 * write.c (fixup_segment): fixed missing parens in expression
4008 checking for byte or word overflow.

4022 * tc-i386.h : new coff defines
4024 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4026 * input-scrub.c (input_scrub_push): call input_file_begin, not
4028 messages.c (as_perror): print ": " between the passed in error and
4029 the strerror, like perror does.
4031 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4033 * Makefile.in: use gas_target instead of modifying target_cpu.
4034 From Steve Chamberlain:
4035 Makefile.in: Handle m68*-*-coff*.
4036 read.c, read.h: add mult argument to s_space
4038 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4039 Motorola and MIT syntax; gas can now assemble either type of
4041 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4047 (write_object_file) call fixup_mdeps
4048 (fixup_segment) set fx_subsy to 0.
4049 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4051 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4054 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4056 * Makefile.in (LIBS): Include opcode library.
4058 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

4078 tc-i960.c (md_ri_to_chars): Always output bout object file in
4079 little endian byte order (used to use endianness of host).
4081 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4083 * config/tc-m68k.c (init_table): Now const. Always include 68851
4084 data, so that "bc" is available to 68040 cache instructions.
4085 Added "tt0", "tt1", and 68ec030 variants.
4086 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4087 (enum _register): Added TT0, TT1.
4088 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4089 line number correctly in "internal error" messages. Don't print
4090 architecture-mismatch message for operand errors.
4092 From Colin Smith (colin@wrs.com):
4093 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4094 than install_operand.

4098 * listing.c (buffer_line): rewind to the start of include
4099 files, they might be included twice.

4108 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4110 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4111 so that we can assemble hand-written libgcc code.
4113 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4115 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4116 has already been formatted (but may still contain %-characters).
4119 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4121 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4122 written with indirection on the last two operands, which can be
4123 either data or address registers. Added a new operand type 'r'
4124 which accepts either register type. Added '(' to notend stuff in
4125 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4127 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

4141 (relax_align): If linkrelax, provide extra padding.
4143 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4144 their not having symbols associated.
4146 * tc-i960.c (norelax, instrument_branches): Default initializer is
4148 (linkrelax): Delete variable definition.

4171 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
4172 being used with args swapped, causing occasional lossage when
4173 refilling buffers after an include file.
4175 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
4177 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4178 version. Discard bogus DONTDEF version.

4183 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
4184 selected architecture, print a message saying so and listing what

4229 * configure.in (mips host): Accept "ultrix" with version number.
4231 * expr.c (floating_constant): Separate "=-" to avoid confusing
4232 ancient or broken compilers.
4234 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
4235 processor/opcode mismatch, so reword the error message.
4236 (md_assemble): If no CPU has been set (even if FPU/PMMU
4237 characteristics have been), default to 68020. Don't need extra
4238 quotes around error string.
4240 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4242 * read.c (potable): Revert sac's incorrect change made Jul 13.

4320 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4322 * write.c (write_object_file): keep the fix_tail clean, which
4323 fixes a bug in -R where relocations were being lost.
4325 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4327 * configure.in: recognize m680x0 as having sun3 emulation mode for

4350 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4352 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
4353 calc the base of relocs correctly.
4354 * tc-a29k.c (parse_operand): allow expressions to be in any section.
4356 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
4358 * as.c, write.c: use -K rather than -k for the broken word warning

4371 * write.c (write_object_file): For b.out format, round up section
4372 start addresses to match required alignment.
4374 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4376 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4377 where gcc looks for it.
4379 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4381 * Makefile.in: Changed some lines to be less confusing for some

4421 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4423 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)

4447 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4449 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4451 * expr.c (operand): if can't work out what sort of operand it is,
4452 then look through FLT_CHARS for a hint.
4454 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4456 * Makefile.in, configure.in: removed traces of namesubdir,
4457 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4458 copyrights to '92, changed some from Cygnus to FSF.
4460 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4461 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4462 copyrights to '92, changed some from Cygnus to FSF.
4464 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4466 * expr.c: If an expression is single comma, then return with
4467 SEG_ABSENT rather than an error - since the sparc front end does
4468 really strange things with things like fbge,a
4470 * as.h: include bfd.h if using many sections
4471 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4472 local labels didn't work.
4473 * listing.c (list_symbol_table): don't core dump when there's no
4475 * write.c, write.h: call fix_new with the right number of args on
4477 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4480 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4482 * app.c: MRI compatibility - allow single quote to start a string.
4483 * as.c: fix typo recently introduced.
4484 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4485 * expr.c: Much rewriting, to accomodate MRI syntax for
4486 expressions. Also easier to read now.
4487 * listing.c: Put back defuns
4488 * read.c: modified to accept MRI syntax, put back listing pseudo
4489 ops so that an assembler built with NO_LISTING ignores list ops
4491 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4492 machine is a SPARC or a 29K.
4493 * config/obj-aout.c: added s_sect pseudo op
4494 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4495 fill in the timestamp.
4496 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4497 anymore, define all the relocs which the tc-<x> bit will use so we
4498 can translate from them to the coff types.
4499 * config/tc-a29k.c: reloc_type isn't ane enum any more
4500 * config/tc-m68k.c: Added NO_RELOC definition.
4502 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4504 * Makefile.in: put header files before C source for TAGS; remove
4505 references to non-existent syscalls.h.
4507 * read.c, write.c subsegs.c: back out the .bss changes.
4509 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4511 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4515 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4517 * symbols.c (local_label_name): symbols now start with ^A.
4519 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4520 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4521 generate these sections. .align: will use NOP_OPCODE or 0
4522 for padding. This is just for being nice to the
4525 * expr.c (operand): changed to generate local label "\001L0"
4526 starting with a ^A so that it is recognized as a local label.
4528 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4530 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4531 i/o opcodes - inb, inw, outb and outw. string manipulation with
4532 att syntax - scmp, slod, smov, ssca, ssto.
4534 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4535 to just after .file .
4537 In obj_crawl_symbol_chain() where it tries to put the external
4538 symbols apart, with the condition:
4539 (!S_IS_DEFINED(symbolP) &&
4540 !S_IS_DEBUG(symbolP) &&
4541 !SF_GET_STATICS(symbolP))
4542 it was moving too many symbols out. So I switch it back to the
4544 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4546 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4547 so that we don't use the F_RELFLG which make the linker complain
4548 that somebody has stripped the relocation info.
4550 Also, the AIX ld program require that the relocation table
4551 is sorted by r_vaddr like the standard ATT assembler does.
4553 [he also changed the sizeof(struct ...)'s into the coff
4554 style FOOSZ macros. I'm not sure this is right, but I can't
4555 remember why. xoxorich.]
4557 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4559 * Makefile.in, configure.in, doc: use the doc. Build it, install
4562 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4564 * read.c: white space and comments only.
4566 * configure.in: use the new atof-ns32.c for ns32k.
4568 * write.c: comment change only.
4570 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4571 aren't yet integrated.
4573 * tc-i860.[hc]: blew off the dust. Something must still be done
4574 about conflicting relocation types.
4576 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4579 * tc-i960.c, tc-sparc.c: white space and comments only.
4581 * tc-a29k.h: delete duplicate macro definition.
4583 * new file atof-ns32k.c copied from hack's last unreleased gas.
4585 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4587 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4590 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4591 ChangeLog's prior to this are sketchy at best. I have logs.
4592 They just aren't ChangeLogs.
