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

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

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

1639 * Extensive changes to permit symbols to contain any expression
1640 type and to delay the computation of the expression until the
1641 value is actually needed. This permits setting symbols to values
1642 calculated based on object code size. Expressions were changed to
1643 no longer be in a section, to stop the overloading of segment and
1644 expression type that previously occurred.
1646 * as.c (big_section, pass1_section, diff_section, absent_section):
1648 (expr_section): Added (used for dummy symbols which hold

1732 (previous_section, previous_subsection): New vars.
1733 (obj_elf_section): Save current place in case DWARF code wants us
1734 to pop back to it. Handle unquoted section name as well as quoted
1735 section name. Don't crash on invalid strings.
1736 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

1758 calculating opP->isiz; this permits the expression size to be
1759 determined as well, later on.

1845 * Removed sy_forward and replaced it with an undefined expression
1846 as the value of a symbol.
1847 * struc-symbol.h (struct symbol): Removed sy_forward field. Added
1848 sy_resolved and sy_resolving single bit fields.
1849 * symbols.c (symbol_new): Don't initialize sy_forward field.
1850 (resolve_symbol_value): New function to adjust symbol value by
1851 fragment address, using recursion to resolve forward symbols.

1853 * read.c (pseudo_set): Set symbolP->sy_value to an undefined
1854 expression rather than setting symbolP->sy_forward.
1855 * write.c (write_object_file): Use resolve_symbol_value on
1856 symbols, keeping the common case (the old behaviour) inline.

2852 than ECOFF line number information.
2853 (obj_ecoff_stab): Accept non-zero values for stabs line number.

2914 dependencies are read, not when they are used).
2916 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
2917 a29k .bss section; the mondfe program doesn't like it.

2962 process relocs if there aren't any relocs to process. Avoids
2963 malloc/free bug on SCO too.

2966 avoid some redefinition complaints on some systems.
2967 (const, volatile): Don't need these conditionally defined if we
2968 use CONST and VOLATILE from ansidecl.h.
2969 (seg_name): Use CONST, not const.
2971 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
2973 * config/tc-mips.c: Reindented to GNU standards.

2977 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
2978 (fixup_segment): Add a29k special case; the linker is not prepared
2979 to see a segment offset here.

2984 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2986 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3006 * Makefile.in (targ-cpu.o): Depend on config.h.
3008 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3010 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3011 dropping a space immediately following an identifier.
3012 * expr.c, write.c: Rewrote assert expressions to not use multiple
3013 lines; I don't think that can be done portably.
3014 * config/tc-mips.c (macro): Use $AT if target register is zero in
3015 load instruction, which it can be for a floating point load.
3017 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3038 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3040 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3041 to be on a single line.

3089 prototypes for all static functions. Moved existing minimal
3090 debugging format support info #ifndef OBJ_ECOFF blocks.

3093 all callers accordingly.
3094 (tc_get_register): Renamed from get_register, and made non-static.
3096 * config/mips-big.mt, config/mips-lit.mt: New files. Define

3139 * make-gas.com: Find obstack.obj if it's not in the current
3141 * read.c (s_ignore): Don't declare is_end_of_line. It's
3142 redundant, and triggers a VMS gcc compiler bug.
3144 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3145 current segment as an argument. (Ignored in all cases but VMS.)
3146 All callers and definitions changed.

3443 md_relax_table): Use default zero initialization.
3444 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3445 latter, instead of selecting with preprocessor conditionals.
3447 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3449 * configure.in: recognise all sparclite variants

3459 * expr.c (operand): If character other than comma or newline is a
3460 logical end-of-line character, use the newline case.
3461 From Eric Youngdale:
3462 (operand): Set X_add_number field for floating-point numbers.
3463 (operand): Treat zero byte as end-of-operand.
3465 * configure.in (per-target): Look for with_bfd_assembler option.
3466 For now, only accept "no", until the merge is done.
3468 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3469 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

3475 * expr.c: Add "const" modifier to hex_value.
3476 * symbols.c: Finish conversion to S_* macros in the VMS only
3477 parts of the program. Add "const" modifier to
3478 md_[long,short]_jump_size. Remove declaration of const_flag
3479 (which will be declared in obj-vms.h).
3480 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3481 Fix arguments to VMS_write_object_file.
3482 * config-gas.com: New file. Script for VMS systems to set up the
3483 configuration to build gas for VMS, and create config.status.
3484 * make-gas.com: Redone to work with new scheme.
3485 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3487 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3488 will swap bytes if needed on a big endian system. Use throughout
3490 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3491 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3492 types of malformed stabs. Change parsing algorithm so that we are
3493 more certain of having all of the information that we need on hand.
3494 * obj-vms.c (final_forward_reference): New function, used to help
3495 resolve the data types of as many struct elements as possible
3496 when some part of the struct is not fully defined by the compiler.

3499 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3500 as symbols as well in the object file. Look for external functions
3501 that start with "__vt.", and turn them into variables, since the
3502 g++ compiler is incapable of doing this.
3503 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3505 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3506 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3507 have the name of the source file yet.
3508 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3510 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3512 * read.c (s_data): Always use "data_section", since it'll map to
3513 SEG_DATA or SEG_E1 if needed.
3514 (s_lcomm): Likewise with bss_section.
3515 (s_fill): Use memset, not bzero.
3517 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3538 (section_alignment): Declare only if not BFD_ASSEMBLER.
3539 (big_section, reg_section, pass1_section, diff_section,
3540 absent_section, text_section, data_section, bss_section): If
3541 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3542 mapping to segT enum values.
3543 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3544 if these are used or defined, if BFD_ASSEMBLER.
3545 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3546 subseg_new split into two functions.
3547 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3549 * as.h (volatile): Don't define if already defined.
3550 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3552 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3553 declare with format attribute for -Wformat checking.
3555 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3557 * app.c, config/tc-*.c: Don't include read.h, since it is already
3560 * These are based on patches from Minh Tran-le
3561 <mtranle@paris.intellicorp.com>.
3562 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3563 obj_format coffbfd and gas_target i386coff for target.
3564 (i[34]86-*-isc*): New host (uses sysv).
3565 * config/i386aix.mt: Removed (no longer used).
3566 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3568 (LDFLAGS): Added, defined as -shlib.
3569 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3570 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3571 (DOT_LABEL_PREFIX): Define.
3572 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3573 name rather than L0\001.
3574 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3576 * symbols.c, symbols.h (local_bss_counter): Removed.
3577 * write.c (write_object_file): bss no longer uses

3585 (size_section): Restored sanity check.
3586 (do_relocs_for): Base section address on s_paddr rather than
3587 computing it. Adjust a29k R_IHIHALF special case to account for
3588 section paddr (used to require paddr to be zero). If there are no
3589 reclos, set s_relptr to 0. Set relocation size in object_headers.
3590 (fill_section): Always set s_vaddr here, removing
3591 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3592 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3593 Set STYP_INFO for .comment.

3597 H_{SET,GET}_* macros.
3598 (do_linenos_for): Set lineno size in object_headers.
3599 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3600 set s_vaddr here. If string_byte_count remains 4, set it back to
3601 0, and only write strings out if there are some. Call
3602 fill_section before do_relocs_for and do_linenos_for.
3603 (obj_coff_section): Handle optional quoted second argument giving
3604 section characteristics.
3605 (obj_coff_bss): Added to handle .bss.
3606 (obj_coff_ident): Added to handle .ident (puts string in .comment

3626 (do_scrub_next_char): For \", return " not '.
3627 (symbol_chars): Now const.
3629 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3630 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3632 * config/obj-coff.h: Don't use #elif.
3634 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3635 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3637 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
3639 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

3661 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3662 using ZERO_BASED_SEGMENTS.
3663 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3664 never set segment address for SEG_E2 (.bss) and don't write out
3665 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3666 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3667 definitions, and don't merge tags with non-tags. Check for .bf
3668 rather than just checking whether the second character is b and
3669 the third character is f.
3670 (obj_coff_val): gcc can generate values which we don't handle
3671 correctly; discard information for now, since it only affects the
3672 debugging information.

3674 (yank_symbols): Don't merge labels.
3675 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3730 options. Updated options documentation for m68k. Some minor
3731 wording/punctuation changes.

3813 * all files: Whitespace changes for GNU indentation style, done by
3814 GNU `indent'. Some cleanup still needed, especially of comments.
3816 * configure.in: No te-386bsd.h file exists; don't try to use it.
3818 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
3820 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
3821 could be doing emulation.
3823 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3826 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

3853 consistently const, and always initialized them. Included read.h.
3855 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
3857 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
3858 constant will not fit in an immediate field.
3859 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
3861 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
3863 * obj-coff.c (callj_table): Delete global variable.

3870 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
3871 with a single set using PARAMS macro.
3873 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

3878 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
3879 so widening works consistently.
3881 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
3883 * version.c: Put conditional "const" before version_string, not
3884 before dummy function for VMS. Now version 1.91.03.
3886 * app.c (do_scrub_next_char): Need double-\ before `000' to show
3887 printed rep of null character.
3889 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
3891 * obj-coffbfd.c (write_object_file): check return value of
3894 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3896 * Support for i386-sysv.
3897 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
3898 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
3899 be used to set them all to zero as was done before.
3900 (fill_section): segment addresses now set in write_object_file.
3901 (fill_section): Don't set STYP_NOLOAD for .bss section.
3902 (fixup_segment): 386 uses strange common symbol format.
3903 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
3904 compatibility with SVR3.2 linker.
3905 * configure.in: i386-sysv and i386-sco use coffbfd.
3907 * app.c (do_scrub_next_char): discard whitespace after a label.

3916 fix i960+non-bfd coff bit rot.
3917 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
3918 support for C source listings. (obj_coff_endef): look in the right
3919 part of the symbol for the symbol name
3921 * tc-m68k.c (get_num): make it work for all segments, not just the
3924 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
3926 * configure.in: recognize i386-*-bsd emulation.

3935 * tc-z8k.c: lots of bug fixes
3937 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3939 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3940 #elif, since it is not supported by old compilers.
3941 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3942 couple of expressions in tc-m68k.c.
3944 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3946 * read.c (cons): If NO_RELOC is defined, use it.
3948 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3950 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3952 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3953 local labels to start with a .) and set REGISTER_PREFIX to %.
3954 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3956 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

3970 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
3972 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3973 sections starting from zero, rather than making them consecutive.
3974 This makes subsequent reloc calculations easier, esp if the object
3975 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3976 allocate lcomm in .data rather than in .bss. It seems that some
3977 tools can't cope with a non-zero sized bss before linkage.
3979 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3981 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3982 throughout. That enum no longer means what we thought it meant.

3985 "-mno-688[58]1" options.
3987 * tc-m68k.c: Added CPU32 support.

3996 Change LIBDEPS dependence to LIBS.
3998 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4000 * Makefile.in (install): if $(tooldir) exists, install as in
4003 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4005 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4006 .word is < -32768 or > 32767. The -J flag causes the error to be
4007 ignored. This is to catch over-sized switches generated by gcc on
4008 systems which don't support the broken .word hack.
4009 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4010 write.c (fixup_segment): check for signed .word overflow if
4011 WARN_SIGNED_OVERFLOW_WORD.
4013 * write.c (fixup_segment): fixed missing parens in expression
4014 checking for byte or word overflow.
4016 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
4017 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
4018 WARN_SIGNED_OVERFLOW_WORD.

4026 * obj-coffbfd.h : added stuff
4027 * tc-i386.c (tc_coff_fix2rtype): new function
4028 * tc-i386.h : new coff defines
4030 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4032 * input-scrub.c (input_scrub_push): call input_file_begin, not
4034 messages.c (as_perror): print ": " between the passed in error and
4035 the strerror, like perror does.
4037 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4039 * Makefile.in: use gas_target instead of modifying target_cpu.
4040 From Steve Chamberlain:
4041 Makefile.in: Handle m68*-*-coff*.
4042 read.c, read.h: add mult argument to s_space
4044 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4045 Motorola and MIT syntax; gas can now assemble either type of
4047 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
4048 From Steve Chamberlain:
4049 m68kcoff.mt: for m68k COFF.
4050 obj-coffbfd.c: (fixup_mdeps) added

4053 (write_object_file) call fixup_mdeps
4054 (fixup_segment) set fx_subsy to 0.
4055 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4057 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4060 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4062 * Makefile.in (LIBS): Include opcode library.
4064 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
4066 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

4084 tc-i960.c (md_ri_to_chars): Always output bout object file in
4085 little endian byte order (used to use endianness of host).
4087 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4089 * config/tc-m68k.c (init_table): Now const. Always include 68851
4090 data, so that "bc" is available to 68040 cache instructions.
4091 Added "tt0", "tt1", and 68ec030 variants.
4092 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4093 (enum _register): Added TT0, TT1.
4094 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4095 line number correctly in "internal error" messages. Don't print
4096 architecture-mismatch message for operand errors.
4098 From Colin Smith (colin@wrs.com):
4099 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4100 than install_operand.

4104 * listing.c (buffer_line): rewind to the start of include
4105 files, they might be included twice.

4112 one element of a family.
4114 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
4116 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
4117 so that we can assemble hand-written libgcc code.
4119 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4121 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4122 has already been formatted (but may still contain %-characters).
4125 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4127 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4128 written with indirection on the last two operands, which can be
4129 either data or address registers. Added a new operand type 'r'
4130 which accepts either register type. Added '(' to notend stuff in
4131 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
4133 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
4135 * as.h (enum _relax_state): Start off at one, not zero, to better

4145 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
4146 defined, call it. Change segments before calling fixup_segment.
4147 (relax_align): If linkrelax, provide extra padding.
4149 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
4150 their not having symbols associated.
4152 * tc-i960.c (norelax, instrument_branches): Default initializer is
4154 (linkrelax): Delete variable definition.

4177 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
4178 being used with args swapped, causing occasional lossage when
4179 refilling buffers after an include file.
4181 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
4183 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
4184 version. Discard bogus DONTDEF version.
4185 (as_warn, as_bad, as_fatal): Likewise.
4187 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
4189 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
4190 selected architecture, print a message saying so and listing what

4208 if TN_SUN3; otherwise align to 2**N-byte bounary.
4210 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4212 * read.c (s_fill): make the .fill size clamped error a warn and
4213 fix bug where 0's were always placed.
4215 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
4216 two bytes of any constant with 0xff:

4220 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
4221 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

4231 fx_offset into account.
4233 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
4235 * configure.in (mips host): Accept "ultrix" with version number.
4237 * expr.c (floating_constant): Separate "=-" to avoid confusing
4238 ancient or broken compilers.
4240 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
4241 processor/opcode mismatch, so reword the error message.
4242 (md_assemble): If no CPU has been set (even if FPU/PMMU
4243 characteristics have been), default to 68020. Don't need extra
4244 quotes around error string.
4246 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4248 * read.c (potable): Revert sac's incorrect change made Jul 13.

4326 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4328 * write.c (write_object_file): keep the fix_tail clean, which
4329 fixes a bug in -R where relocations were being lost.

4378 start addresses to match required alignment.
4380 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4382 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4383 where gcc looks for it.
4385 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4387 * Makefile.in: Changed some lines to be less confusing for some

4453 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4455 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4457 * expr.c (operand): if can't work out what sort of operand it is,
4458 then look through FLT_CHARS for a hint.
4460 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4462 * Makefile.in, configure.in: removed traces of namesubdir,

4466 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4467 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4468 copyrights to '92, changed some from Cygnus to FSF.
4470 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4472 * expr.c: If an expression is single comma, then return with
4473 SEG_ABSENT rather than an error - since the sparc front end does
4474 really strange things with things like fbge,a
4476 * as.h: include bfd.h if using many sections
4477 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4478 local labels didn't work.
4479 * listing.c (list_symbol_table): don't core dump when there's no
4481 * write.c, write.h: call fix_new with the right number of args on
4483 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4486 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4488 * app.c: MRI compatibility - allow single quote to start a string.
4489 * as.c: fix typo recently introduced.
4490 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4491 * expr.c: Much rewriting, to accomodate MRI syntax for
4492 expressions. Also easier to read now.
4493 * listing.c: Put back defuns
4494 * read.c: modified to accept MRI syntax, put back listing pseudo
4495 ops so that an assembler built with NO_LISTING ignores list ops
4497 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4498 machine is a SPARC or a 29K.
4499 * config/obj-aout.c: added s_sect pseudo op
4500 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4501 fill in the timestamp.
4502 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4503 anymore, define all the relocs which the tc-<x> bit will use so we
4504 can translate from them to the coff types.
4505 * config/tc-a29k.c: reloc_type isn't ane enum any more
4506 * config/tc-m68k.c: Added NO_RELOC definition.
4508 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4510 * Makefile.in: put header files before C source for TAGS; remove
4511 references to non-existent syscalls.h.
4513 * read.c, write.c subsegs.c: back out the .bss changes.
4515 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4517 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4521 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4523 * symbols.c (local_label_name): symbols now start with ^A.
4525 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4526 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4527 generate these sections. .align: will use NOP_OPCODE or 0
4528 for padding. This is just for being nice to the
4531 * expr.c (operand): changed to generate local label "\001L0"
4532 starting with a ^A so that it is recognized as a local label.
4534 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4536 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4537 i/o opcodes - inb, inw, outb and outw. string manipulation with
4538 att syntax - scmp, slod, smov, ssca, ssto.
4540 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4541 to just after .file .
4543 In obj_crawl_symbol_chain() where it tries to put the external
4544 symbols apart, with the condition:
4545 (!S_IS_DEFINED(symbolP) &&
4546 !S_IS_DEBUG(symbolP) &&
4547 !SF_GET_STATICS(symbolP))
4548 it was moving too many symbols out. So I switch it back to the
4550 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4552 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4553 so that we don't use the F_RELFLG which make the linker complain
4554 that somebody has stripped the relocation info.
4556 Also, the AIX ld program require that the relocation table
4557 is sorted by r_vaddr like the standard ATT assembler does.
4559 [he also changed the sizeof(struct ...)'s into the coff
4560 style FOOSZ macros. I'm not sure this is right, but I can't
4561 remember why. xoxorich.]
4563 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4565 * Makefile.in, configure.in, doc: use the doc. Build it, install
4568 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4570 * read.c: white space and comments only.
4572 * configure.in: use the new atof-ns32.c for ns32k.
4574 * write.c: comment change only.
4576 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4577 aren't yet integrated.
4579 * tc-i860.[hc]: blew off the dust. Something must still be done
4580 about conflicting relocation types.
4582 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4585 * tc-i960.c, tc-sparc.c: white space and comments only.
4587 * tc-a29k.h: delete duplicate macro definition.
4589 * new file atof-ns32k.c copied from hack's last unreleased gas.
4591 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4593 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4596 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4597 ChangeLog's prior to this are sketchy at best. I have logs.
4598 They just aren't ChangeLogs.
