43 is 4 bytes, pick up the size from relocation itself.
44 (fixup_segment): Do not complain that a value is too small for

71 BFD_RELOC_MIPS_GPREL. Added new case a.
72 (set_at, load_register, macro): Changed calls to macro_build to
73 pass new argument for i, j and o cases.

152 the .subspace directive. Likewise for the section alignment.
153 Pass the current space to update_subspace and create_new_subspace.
154 (pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES

429 through inclusion of tc-hppa.h. Delete all forward declarations
430 for functions only used within tc-hppa.c, likewise for structures,
431 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
432 conditional code in a few small places.

440 Add comments to functions. Delete unused functions, variables,
441 #defines, etc. Delete unused members within structures. Delete
442 ldil;ble hacks -- it is believed they were installed to work
443 around old gas bugs. Avoid using mixed case for local
444 functions, variables, and structures. Fix formatting problems
445 not found by GNU-indent. Add FIXME notices for things which
446 should be worked on the near future. Delete lots of old
447 useless (1.36 PA-SOM) code.

1525 are also magic, and have special default flag settings.
1526 (obj_elf_frob_symbol): Since the return value from this function

1590 * Extensive changes to permit symbols to contain any expression
1591 type and to delay the computation of the expression until the
1592 value is actually needed. This permits setting symbols to values
1593 calculated based on object code size. Expressions were changed to
1594 no longer be in a section, to stop the overloading of segment and
1595 expression type that previously occurred.
1597 * as.c (big_section, pass1_section, diff_section, absent_section):
1599 (expr_section): Added (used for dummy symbols which hold

1683 (previous_section, previous_subsection): New vars.
1684 (obj_elf_section): Save current place in case DWARF code wants us
1685 to pop back to it. Handle unquoted section name as well as quoted
1686 section name. Don't crash on invalid strings.

1799 sy_resolved and sy_resolving single bit fields.
1800 * symbols.c (symbol_new): Don't initialize sy_forward field.

2833 * as.h (const, volatile): Put these definitions back, and use
2836 * doc/as.texinfo: First pass at using new texinfo features --
2837 variables, conditional tests. Far from complete.

2865 dependencies are read, not when they are used).
2867 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
2868 a29k .bss section; the mondfe program doesn't like it.

2889 source directory, if that's not the current directory.
2891 * configure.in (per-host): Accept MIPS host with BSD version

2917 avoid some redefinition complaints on some systems.
2918 (const, volatile): Don't need these conditionally defined if we
2919 use CONST and VOLATILE from ansidecl.h.
2920 (seg_name): Use CONST, not const.
2922 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
2924 * config/tc-mips.c: Reindented to GNU standards.

2928 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
2929 (fixup_segment): Add a29k special case; the linker is not prepared
2930 to see a segment offset here.
2932 * app.c (do_scrub_next_char): Added new state, 10, modifying state

2935 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2937 * Makefile.in: add dvi target; as-$(config).texinfo might live in

2953 bignums, but don't emit error message.
2955 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
2957 * Makefile.in (targ-cpu.o): Depend on config.h.
2959 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
2961 * app.c (do_scrub_next_char): Added new state, 9, to avoid
2962 dropping a space immediately following an identifier.
2963 * expr.c, write.c: Rewrote assert expressions to not use multiple
2964 lines; I don't think that can be done portably.
2965 * config/tc-mips.c (macro): Use $AT if target register is zero in
2966 load instruction, which it can be for a floating point load.
2968 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

2989 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
2991 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
2992 to be on a single line.
2994 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
2996 * Makefile.in (config.h): Create file, writing out definitions of

3040 prototypes for all static functions. Moved existing minimal
3041 debugging format support info #ifndef OBJ_ECOFF blocks.

3090 * make-gas.com: Find obstack.obj if it's not in the current
3092 * read.c (s_ignore): Don't declare is_end_of_line. It's
3093 redundant, and triggers a VMS gcc compiler bug.
3095 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3096 current segment as an argument. (Ignored in all cases but VMS.)
3097 All callers and definitions changed.

3394 md_relax_table): Use default zero initialization.
3395 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3396 latter, instead of selecting with preprocessor conditionals.
3398 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3400 * configure.in: recognise all sparclite variants
3402 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3408 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3410 * expr.c (operand): If character other than comma or newline is a
3411 logical end-of-line character, use the newline case.
3412 From Eric Youngdale:
3413 (operand): Set X_add_number field for floating-point numbers.
3414 (operand): Treat zero byte as end-of-operand.
3416 * configure.in (per-target): Look for with_bfd_assembler option.
3417 For now, only accept "no", until the merge is done.
3419 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3420 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3421 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3422 * read.c: Finish conversion to S_* macros in the VMS only
3423 parts of the program. Add "const" modifier to hex_value.
3424 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3426 * expr.c: Add "const" modifier to hex_value.
3427 * symbols.c: Finish conversion to S_* macros in the VMS only
3428 parts of the program. Add "const" modifier to
3429 md_[long,short]_jump_size. Remove declaration of const_flag
3430 (which will be declared in obj-vms.h).
3431 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3432 Fix arguments to VMS_write_object_file.
3433 * config-gas.com: New file. Script for VMS systems to set up the
3434 configuration to build gas for VMS, and create config.status.
3435 * make-gas.com: Redone to work with new scheme.
3436 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3438 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3439 will swap bytes if needed on a big endian system. Use throughout
3441 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3442 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3443 types of malformed stabs. Change parsing algorithm so that we are
3444 more certain of having all of the information that we need on hand.
3445 * obj-vms.c (final_forward_reference): New function, used to help
3446 resolve the data types of as many struct elements as possible
3447 when some part of the struct is not fully defined by the compiler.

3450 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3451 as symbols as well in the object file. Look for external functions
3452 that start with "__vt.", and turn them into variables, since the
3453 g++ compiler is incapable of doing this.
3454 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3456 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3457 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3458 have the name of the source file yet.
3459 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3461 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3463 * read.c (s_data): Always use "data_section", since it'll map to
3464 SEG_DATA or SEG_E1 if needed.
3465 (s_lcomm): Likewise with bss_section.
3466 (s_fill): Use memset, not bzero.
3468 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3490 (big_section, reg_section, pass1_section, diff_section,
3491 absent_section, text_section, data_section, bss_section): If
3492 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3493 mapping to segT enum values.
3494 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3495 if these are used or defined, if BFD_ASSEMBLER.
3496 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3497 subseg_new split into two functions.
3498 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3500 * as.h (volatile): Don't define if already defined.
3501 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3503 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3504 declare with format attribute for -Wformat checking.
3506 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3508 * app.c, config/tc-*.c: Don't include read.h, since it is already
3511 * These are based on patches from Minh Tran-le
3512 <mtranle@paris.intellicorp.com>.
3513 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3514 obj_format coffbfd and gas_target i386coff for target.
3515 (i[34]86-*-isc*): New host (uses sysv).
3516 * config/i386aix.mt: Removed (no longer used).
3517 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3519 (LDFLAGS): Added, defined as -shlib.
3520 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3521 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3522 (DOT_LABEL_PREFIX): Define.
3523 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3524 name rather than L0\001.
3525 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3527 * symbols.c, symbols.h (local_bss_counter): Removed.
3528 * write.c (write_object_file): bss no longer uses
3529 local_bss_counter. Pass correct data and bss size to
3530 VMS_write_object_file.

3536 (size_section): Restored sanity check.
3537 (do_relocs_for): Base section address on s_paddr rather than
3538 computing it. Adjust a29k R_IHIHALF special case to account for
3539 section paddr (used to require paddr to be zero). If there are no
3540 reclos, set s_relptr to 0. Set relocation size in object_headers.
3541 (fill_section): Always set s_vaddr here, removing
3542 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3543 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3544 Set STYP_INFO for .comment.

3548 H_{SET,GET}_* macros.
3549 (do_linenos_for): Set lineno size in object_headers.
3550 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3551 set s_vaddr here. If string_byte_count remains 4, set it back to
3552 0, and only write strings out if there are some. Call
3553 fill_section before do_relocs_for and do_linenos_for.
3554 (obj_coff_section): Handle optional quoted second argument giving
3555 section characteristics.
3556 (obj_coff_bss): Added to handle .bss.
3557 (obj_coff_ident): Added to handle .ident (puts string in .comment

3577 (do_scrub_next_char): For \", return " not '.
3578 (symbol_chars): Now const.
3580 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3581 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3583 * config/obj-coff.h: Don't use #elif.
3585 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3586 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3588 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
3590 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

3612 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3613 using ZERO_BASED_SEGMENTS.
3614 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3615 never set segment address for SEG_E2 (.bss) and don't write out
3616 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3617 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3618 definitions, and don't merge tags with non-tags. Check for .bf
3619 rather than just checking whether the second character is b and
3620 the third character is f.
3621 (obj_coff_val): gcc can generate values which we don't handle
3622 correctly; discard information for now, since it only affects the
3623 debugging information.
3624 (tag_find_or_name): Don't insert tags in the symbol table.
3625 (yank_symbols): Don't merge labels.
3626 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3804 consistently const, and always initialized them. Included read.h.
3806 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
3808 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
3809 constant will not fit in an immediate field.
3810 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
3812 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
3814 * obj-coff.c (callj_table): Delete global variable.

3829 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
3830 so widening works consistently.
3832 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
3834 * version.c: Put conditional "const" before version_string, not
3835 before dummy function for VMS. Now version 1.91.03.
3837 * app.c (do_scrub_next_char): Need double-\ before `000' to show
3838 printed rep of null character.
3840 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
3842 * obj-coffbfd.c (write_object_file): check return value of
3845 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3847 * Support for i386-sysv.
3848 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
3849 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
3850 be used to set them all to zero as was done before.
3851 (fill_section): segment addresses now set in write_object_file.
3852 (fill_section): Don't set STYP_NOLOAD for .bss section.
3853 (fixup_segment): 386 uses strange common symbol format.
3854 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
3855 compatibility with SVR3.2 linker.
3856 * configure.in: i386-sysv and i386-sco use coffbfd.

3872 * tc-m68k.c (get_num): make it work for all segments, not just the
3875 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

3886 * tc-z8k.c: lots of bug fixes
3888 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3890 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3891 #elif, since it is not supported by old compilers.
3892 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3893 couple of expressions in tc-m68k.c.
3895 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3897 * read.c (cons): If NO_RELOC is defined, use it.
3899 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3901 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3903 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3904 local labels to start with a .) and set REGISTER_PREFIX to %.
3905 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
3907 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

3921 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
3923 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3924 sections starting from zero, rather than making them consecutive.
3925 This makes subsequent reloc calculations easier, esp if the object
3926 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3927 allocate lcomm in .data rather than in .bss. It seems that some
3928 tools can't cope with a non-zero sized bss before linkage.
3930 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3932 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
3933 throughout. That enum no longer means what we thought it meant.

3951 * Makefile.in (install): if $(tooldir) exists, install as in
3954 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3956 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3957 .word is < -32768 or > 32767. The -J flag causes the error to be
3958 ignored. This is to catch over-sized switches generated by gcc on
3959 systems which don't support the broken .word hack.
3960 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3961 write.c (fixup_segment): check for signed .word overflow if
3962 WARN_SIGNED_OVERFLOW_WORD.
3964 * write.c (fixup_segment): fixed missing parens in expression
3965 checking for byte or word overflow.

3981 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
3983 * input-scrub.c (input_scrub_push): call input_file_begin, not
3985 messages.c (as_perror): print ": " between the passed in error and
3986 the strerror, like perror does.
3988 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

3991 From Steve Chamberlain:
3992 Makefile.in: Handle m68*-*-coff*.
3993 read.c, read.h: add mult argument to s_space
3995 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3996 Motorola and MIT syntax; gas can now assemble either type of
3998 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4005 (fixup_segment) set fx_subsy to 0.
4006 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4008 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4011 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4013 * Makefile.in (LIBS): Include opcode library.

4038 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4040 * config/tc-m68k.c (init_table): Now const. Always include 68851
4041 data, so that "bc" is available to 68040 cache instructions.
4042 Added "tt0", "tt1", and 68ec030 variants.
4043 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4044 (enum _register): Added TT0, TT1.
4045 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4046 line number correctly in "internal error" messages. Don't print
4047 architecture-mismatch message for operand errors.
4049 From Colin Smith (colin@wrs.com):
4050 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4051 than install_operand.

4072 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4073 has already been formatted (but may still contain %-characters).
4076 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4078 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4079 written with indirection on the last two operands, which can be
4080 either data or address registers. Added a new operand type 'r'
4081 which accepts either register type. Added '(' to notend stuff in
4082 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4101 their not having symbols associated.
4103 * tc-i960.c (norelax, instrument_branches): Default initializer is
4105 (linkrelax): Delete variable definition.

4129 being used with args swapped, causing occasional lossage when
4130 refilling buffers after an include file.

4188 * expr.c (floating_constant): Separate "=-" to avoid confusing
4189 ancient or broken compilers.
4191 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
4192 processor/opcode mismatch, so reword the error message.
4193 (md_assemble): If no CPU has been set (even if FPU/PMMU
4194 characteristics have been), default to 68020. Don't need extra
4195 quotes around error string.

4272 subsegment with a value which might interfere with out -R hackery.
4273 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
4274 rather than use ugly if tree. (init_regtable): insert register
4275 names into symbol table.
4277 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
4279 * write.c (write_object_file): keep the fix_tail clean, which
4280 fixes a bug in -R where relocations were being lost.
4282 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
4284 * configure.in: recognize m680x0 as having sun3 emulation mode for
4285 vxworks environment.
4287 Sun May 31 05:33:00 1992 david d `zoo' zuhn (zoo@cygnus.com)

4307 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4309 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
4310 calc the base of relocs correctly.
4311 * tc-a29k.c (parse_operand): allow expressions to be in any section.
4313 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
4315 * as.c, write.c: use -K rather than -k for the broken word warning
4318 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
4320 * Makefile.in: do not print recursion lines.
4322 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)

4326 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4328 * write.c (write_object_file): For b.out format, round up section
4329 start addresses to match required alignment.
4331 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4333 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4334 where gcc looks for it.
4336 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4338 * Makefile.in: Changed some lines to be less confusing for some
4341 * input-file.c: Conditionalize on _IOFBF, not VMS.
4343 * read.c, write.c: Change a series of ifdef/elif to
4344 ifdef/else/ifdef etc.
4346 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
4348 * symbols.c (fb_label_init): fix sizeof to memset.

4358 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4360 * flonum-const.c: renamed flonum-konst.c to stop dos name
4363 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
4365 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
4366 tc-m68k.h to te-sun3.h.
4368 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
4370 * configure.in: vxworks68 gets te-sun3.h.
4372 * expr.c: remove limitation that local_labels_dollar or
4373 local_labels_fb must be < 10.
4375 * symbols.c: remove local_labels_dollar, replace with a function
4376 interface for a sparse array. All users adjusted.
4378 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4380 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4382 * doc/Makefile.in: commented out line for building as-all.texinfo.
4385 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
4387 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

4399 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4401 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4404 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4406 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4408 * expr.c (operand): if can't work out what sort of operand it is,
4409 then look through FLT_CHARS for a hint.
4411 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4413 * Makefile.in, configure.in: removed traces of namesubdir,
4414 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4415 copyrights to '92, changed some from Cygnus to FSF.
4417 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4418 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4419 copyrights to '92, changed some from Cygnus to FSF.
4421 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4423 * expr.c: If an expression is single comma, then return with
4424 SEG_ABSENT rather than an error - since the sparc front end does
4425 really strange things with things like fbge,a
4427 * as.h: include bfd.h if using many sections
4428 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4429 local labels didn't work.
4430 * listing.c (list_symbol_table): don't core dump when there's no
4432 * write.c, write.h: call fix_new with the right number of args on
4434 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4437 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4439 * app.c: MRI compatibility - allow single quote to start a string.
4440 * as.c: fix typo recently introduced.
4441 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4442 * expr.c: Much rewriting, to accomodate MRI syntax for
4443 expressions. Also easier to read now.
4444 * listing.c: Put back defuns
4445 * read.c: modified to accept MRI syntax, put back listing pseudo
4446 ops so that an assembler built with NO_LISTING ignores list ops
4448 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4449 machine is a SPARC or a 29K.
4450 * config/obj-aout.c: added s_sect pseudo op
4451 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4452 fill in the timestamp.
4453 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4454 anymore, define all the relocs which the tc-<x> bit will use so we
4455 can translate from them to the coff types.
4456 * config/tc-a29k.c: reloc_type isn't ane enum any more
4457 * config/tc-m68k.c: Added NO_RELOC definition.
4459 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4461 * Makefile.in: put header files before C source for TAGS; remove
4462 references to non-existent syscalls.h.
4464 * read.c, write.c subsegs.c: back out the .bss changes.
4466 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4468 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4472 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4474 * symbols.c (local_label_name): symbols now start with ^A.
4476 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4477 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4478 generate these sections. .align: will use NOP_OPCODE or 0
4479 for padding. This is just for being nice to the
4482 * expr.c (operand): changed to generate local label "\001L0"
4483 starting with a ^A so that it is recognized as a local label.
4485 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4487 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4488 i/o opcodes - inb, inw, outb and outw. string manipulation with
4489 att syntax - scmp, slod, smov, ssca, ssto.
4491 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4492 to just after .file .
4494 In obj_crawl_symbol_chain() where it tries to put the external
4495 symbols apart, with the condition:
4496 (!S_IS_DEFINED(symbolP) &&
4497 !S_IS_DEBUG(symbolP) &&
4498 !SF_GET_STATICS(symbolP))
4499 it was moving too many symbols out. So I switch it back to the
4501 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4503 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4504 so that we don't use the F_RELFLG which make the linker complain
4505 that somebody has stripped the relocation info.
4507 Also, the AIX ld program require that the relocation table
4508 is sorted by r_vaddr like the standard ATT assembler does.
4510 [he also changed the sizeof(struct ...)'s into the coff
4511 style FOOSZ macros. I'm not sure this is right, but I can't
4512 remember why. xoxorich.]
4514 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4516 * Makefile.in, configure.in, doc: use the doc. Build it, install
4519 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4521 * read.c: white space and comments only.
4523 * configure.in: use the new atof-ns32.c for ns32k.
4525 * write.c: comment change only.
4527 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4528 aren't yet integrated.
4530 * tc-i860.[hc]: blew off the dust. Something must still be done
4531 about conflicting relocation types.
4533 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4536 * tc-i960.c, tc-sparc.c: white space and comments only.
4538 * tc-a29k.h: delete duplicate macro definition.
4540 * new file atof-ns32k.c copied from hack's last unreleased gas.
4542 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4544 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4547 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4548 ChangeLog's prior to this are sketchy at best. I have logs.
4549 They just aren't ChangeLogs.
