873 through inclusion of tc-hppa.h. Delete all forward declarations
874 for functions only used within tc-hppa.c, likewise for structures,
875 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
876 conditional code in a few small places.
878 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
879 structures, global variables, forward declarations together.

881 conditional code -- try to group conditional code together
882 into a few places. Make all functions and variables which
883 are only used within tc-hppa.c static. PARAMize all functions.
884 Add comments to functions. Delete unused functions, variables,
885 #defines, etc. Delete unused members within structures. Delete
886 ldil;ble hacks -- it is believed they were installed to work
887 around old gas bugs. Avoid using mixed case for local
888 functions, variables, and structures. Fix formatting problems
889 not found by GNU-indent. Add FIXME notices for things which
890 should be worked on the near future. Delete lots of old

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

964 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
966 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
967 ELF, since the ELF object format does not have these type of
968 relocations. Change the abort into as as_bad and return
969 BFD_RELOC_NONE to silence compiler warnings.
970 (md_assemble): Keep track of the instruction size. Allow white
971 space between the $ and the constant for compatibility with older
972 gases and other assemblers.
973 (i386_operand): Skip spaces between $ and expression.
974 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

2034 * Extensive changes to permit symbols to contain any expression
2035 type and to delay the computation of the expression until the
2036 value is actually needed. This permits setting symbols to values
2037 calculated based on object code size. Expressions were changed to
2038 no longer be in a section, to stop the overloading of segment and
2039 expression type that previously occurred.
2041 * as.c (big_section, pass1_section, diff_section, absent_section):
2043 (expr_section): Added (used for dummy symbols which hold

2243 sy_resolved and sy_resolving single bit fields.
2244 * symbols.c (symbol_new): Don't initialize sy_forward field.

3361 avoid some redefinition complaints on some systems.
3362 (const, volatile): Don't need these conditionally defined if we
3363 use CONST and VOLATILE from ansidecl.h.
3364 (seg_name): Use CONST, not const.
3366 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3368 * config/tc-mips.c: Reindented to GNU standards.

3379 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3381 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3401 * Makefile.in (targ-cpu.o): Depend on config.h.
3403 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3405 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3406 dropping a space immediately following an identifier.
3407 * expr.c, write.c: Rewrote assert expressions to not use multiple
3408 lines; I don't think that can be done portably.
3409 * config/tc-mips.c (macro): Use $AT if target register is zero in
3410 load instruction, which it can be for a floating point load.
3412 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3433 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3435 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3436 to be on a single line.

3484 prototypes for all static functions. Moved existing minimal
3485 debugging format support info #ifndef OBJ_ECOFF blocks.

3536 * read.c (s_ignore): Don't declare is_end_of_line. It's
3537 redundant, and triggers a VMS gcc compiler bug.
3539 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3540 current segment as an argument. (Ignored in all cases but VMS.)
3541 All callers and definitions changed.

3838 md_relax_table): Use default zero initialization.
3839 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3840 latter, instead of selecting with preprocessor conditionals.
3842 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3844 * configure.in: recognise all sparclite variants
3846 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3852 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3854 * expr.c (operand): If character other than comma or newline is a
3855 logical end-of-line character, use the newline case.
3856 From Eric Youngdale:
3857 (operand): Set X_add_number field for floating-point numbers.
3858 (operand): Treat zero byte as end-of-operand.
3860 * configure.in (per-target): Look for with_bfd_assembler option.
3861 For now, only accept "no", until the merge is done.
3863 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3864 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3865 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3866 * read.c: Finish conversion to S_* macros in the VMS only
3867 parts of the program. Add "const" modifier to hex_value.

3870 * expr.c: Add "const" modifier to hex_value.
3871 * symbols.c: Finish conversion to S_* macros in the VMS only
3872 parts of the program. Add "const" modifier to
3873 md_[long,short]_jump_size. Remove declaration of const_flag
3874 (which will be declared in obj-vms.h).
3875 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3876 Fix arguments to VMS_write_object_file.
3877 * config-gas.com: New file. Script for VMS systems to set up the
3878 configuration to build gas for VMS, and create config.status.
3879 * make-gas.com: Redone to work with new scheme.
3880 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3882 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3883 will swap bytes if needed on a big endian system. Use throughout
3885 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3886 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3887 types of malformed stabs. Change parsing algorithm so that we are
3888 more certain of having all of the information that we need on hand.
3889 * obj-vms.c (final_forward_reference): New function, used to help
3890 resolve the data types of as many struct elements as possible
3891 when some part of the struct is not fully defined by the compiler.

3894 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3895 as symbols as well in the object file. Look for external functions
3896 that start with "__vt.", and turn them into variables, since the
3897 g++ compiler is incapable of doing this.
3898 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3900 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3901 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3902 have the name of the source file yet.
3903 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3905 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3907 * read.c (s_data): Always use "data_section", since it'll map to
3908 SEG_DATA or SEG_E1 if needed.
3909 (s_lcomm): Likewise with bss_section.
3910 (s_fill): Use memset, not bzero.
3912 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3933 (section_alignment): Declare only if not BFD_ASSEMBLER.
3934 (big_section, reg_section, pass1_section, diff_section,
3935 absent_section, text_section, data_section, bss_section): If
3936 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3937 mapping to segT enum values.
3938 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3939 if these are used or defined, if BFD_ASSEMBLER.
3940 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3941 subseg_new split into two functions.
3942 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3944 * as.h (volatile): Don't define if already defined.
3945 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3947 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3948 declare with format attribute for -Wformat checking.
3950 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3952 * app.c, config/tc-*.c: Don't include read.h, since it is already
3955 * These are based on patches from Minh Tran-le
3956 <mtranle@paris.intellicorp.com>.
3957 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3958 obj_format coffbfd and gas_target i386coff for target.
3959 (i[34]86-*-isc*): New host (uses sysv).
3960 * config/i386aix.mt: Removed (no longer used).
3961 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3963 (LDFLAGS): Added, defined as -shlib.
3964 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3965 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3966 (DOT_LABEL_PREFIX): Define.
3967 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3968 name rather than L0\001.

3980 (size_section): Restored sanity check.
3981 (do_relocs_for): Base section address on s_paddr rather than
3982 computing it. Adjust a29k R_IHIHALF special case to account for
3983 section paddr (used to require paddr to be zero). If there are no
3984 reclos, set s_relptr to 0. Set relocation size in object_headers.
3985 (fill_section): Always set s_vaddr here, removing
3986 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3987 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3988 Set STYP_INFO for .comment.

3992 H_{SET,GET}_* macros.
3993 (do_linenos_for): Set lineno size in object_headers.
3994 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3995 set s_vaddr here. If string_byte_count remains 4, set it back to
3996 0, and only write strings out if there are some. Call
3997 fill_section before do_relocs_for and do_linenos_for.
3998 (obj_coff_section): Handle optional quoted second argument giving
3999 section characteristics.
4000 (obj_coff_bss): Added to handle .bss.
4001 (obj_coff_ident): Added to handle .ident (puts string in .comment

4021 (do_scrub_next_char): For \", return " not '.
4022 (symbol_chars): Now const.
4024 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4025 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4027 * config/obj-coff.h: Don't use #elif.
4029 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4030 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

4056 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4057 using ZERO_BASED_SEGMENTS.
4058 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4059 never set segment address for SEG_E2 (.bss) and don't write out
4060 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4061 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4062 definitions, and don't merge tags with non-tags. Check for .bf
4063 rather than just checking whether the second character is b and
4064 the third character is f.
4065 (obj_coff_val): gcc can generate values which we don't handle
4066 correctly; discard information for now, since it only affects the
4067 debugging information.
4068 (tag_find_or_name): Don't insert tags in the symbol table.
4069 (yank_symbols): Don't merge labels.
4070 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4273 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4274 so widening works consistently.
4276 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4278 * version.c: Put conditional "const" before version_string, not
4279 before dummy function for VMS. Now version 1.91.03.
4281 * app.c (do_scrub_next_char): Need double-\ before `000' to show
4282 printed rep of null character.
4284 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
4286 * obj-coffbfd.c (write_object_file): check return value of
4289 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4291 * Support for i386-sysv.
4292 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4293 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4294 be used to set them all to zero as was done before.
4295 (fill_section): segment addresses now set in write_object_file.
4296 (fill_section): Don't set STYP_NOLOAD for .bss section.
4297 (fixup_segment): 386 uses strange common symbol format.
4298 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for

4334 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4335 #elif, since it is not supported by old compilers.
4336 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4337 couple of expressions in tc-m68k.c.
4339 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4341 * read.c (cons): If NO_RELOC is defined, use it.
4343 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4345 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4347 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4348 local labels to start with a .) and set REGISTER_PREFIX to %.
4349 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4367 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4368 sections starting from zero, rather than making them consecutive.
4369 This makes subsequent reloc calculations easier, esp if the object
4370 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4371 allocate lcomm in .data rather than in .bss. It seems that some
4372 tools can't cope with a non-zero sized bss before linkage.
4374 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4376 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4395 * Makefile.in (install): if $(tooldir) exists, install as in
4398 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4400 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4401 .word is < -32768 or > 32767. The -J flag causes the error to be
4402 ignored. This is to catch over-sized switches generated by gcc on
4403 systems which don't support the broken .word hack.
4404 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4405 write.c (fixup_segment): check for signed .word overflow if
4406 WARN_SIGNED_OVERFLOW_WORD.

4425 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4427 * input-scrub.c (input_scrub_push): call input_file_begin, not
4429 messages.c (as_perror): print ": " between the passed in error and
4430 the strerror, like perror does.

4435 From Steve Chamberlain:
4436 Makefile.in: Handle m68*-*-coff*.
4437 read.c, read.h: add mult argument to s_space
4439 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4440 Motorola and MIT syntax; gas can now assemble either type of

4450 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4452 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4455 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4457 * Makefile.in (LIBS): Include opcode library.

4482 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4484 * config/tc-m68k.c (init_table): Now const. Always include 68851
4485 data, so that "bc" is available to 68040 cache instructions.
4486 Added "tt0", "tt1", and 68ec030 variants.
4487 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4488 (enum _register): Added TT0, TT1.
4489 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4490 line number correctly in "internal error" messages. Don't print
4491 architecture-mismatch message for operand errors.
4493 From Colin Smith (colin@wrs.com):
4494 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

4516 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4517 has already been formatted (but may still contain %-characters).
4520 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4522 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4523 written with indirection on the last two operands, which can be
4524 either data or address registers. Added a new operand type 'r'
4525 which accepts either register type. Added '(' to notend stuff in
4526 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4545 their not having symbols associated.
4547 * tc-i960.c (norelax, instrument_branches): Default initializer is

4633 ancient or broken compilers.
4635 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
4636 processor/opcode mismatch, so reword the error message.

4751 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4753 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
4754 calc the base of relocs correctly.
4755 * tc-a29k.c (parse_operand): allow expressions to be in any section.
4757 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
4759 * as.c, write.c: use -K rather than -k for the broken word warning
4762 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
4764 * Makefile.in: do not print recursion lines.
4766 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)

4770 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4772 * write.c (write_object_file): For b.out format, round up section
4773 start addresses to match required alignment.
4775 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4777 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4778 where gcc looks for it.
4780 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4782 * Makefile.in: Changed some lines to be less confusing for some
4785 * input-file.c: Conditionalize on _IOFBF, not VMS.
4787 * read.c, write.c: Change a series of ifdef/elif to
4788 ifdef/else/ifdef etc.
4790 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
4792 * symbols.c (fb_label_init): fix sizeof to memset.
4794 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
4796 * Makefile.in: install the man page.
4798 * Makefile.in: pass down MAKEINFO explicitly on info.

4802 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4804 * flonum-const.c: renamed flonum-konst.c to stop dos name
4807 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
4809 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
4810 tc-m68k.h to te-sun3.h.
4812 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
4814 * configure.in: vxworks68 gets te-sun3.h.
4816 * expr.c: remove limitation that local_labels_dollar or
4817 local_labels_fb must be < 10.
4819 * symbols.c: remove local_labels_dollar, replace with a function
4820 interface for a sparse array. All users adjusted.
4822 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4824 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4826 * doc/Makefile.in: commented out line for building as-all.texinfo.
4829 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
4831 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

4843 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4845 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4848 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4850 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4852 * expr.c (operand): if can't work out what sort of operand it is,
4853 then look through FLT_CHARS for a hint.
4855 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4857 * Makefile.in, configure.in: removed traces of namesubdir,
4858 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4859 copyrights to '92, changed some from Cygnus to FSF.
4861 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4862 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4863 copyrights to '92, changed some from Cygnus to FSF.
4865 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4867 * expr.c: If an expression is single comma, then return with
4868 SEG_ABSENT rather than an error - since the sparc front end does
4869 really strange things with things like fbge,a
4871 * as.h: include bfd.h if using many sections
4872 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4873 local labels didn't work.
4874 * listing.c (list_symbol_table): don't core dump when there's no
4876 * write.c, write.h: call fix_new with the right number of args on
4878 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4881 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4883 * app.c: MRI compatibility - allow single quote to start a string.
4884 * as.c: fix typo recently introduced.
4885 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4886 * expr.c: Much rewriting, to accomodate MRI syntax for
4887 expressions. Also easier to read now.
4888 * listing.c: Put back defuns
4889 * read.c: modified to accept MRI syntax, put back listing pseudo
4890 ops so that an assembler built with NO_LISTING ignores list ops
4892 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4893 machine is a SPARC or a 29K.
4894 * config/obj-aout.c: added s_sect pseudo op
4895 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4896 fill in the timestamp.
4897 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4898 anymore, define all the relocs which the tc-<x> bit will use so we
4899 can translate from them to the coff types.
4900 * config/tc-a29k.c: reloc_type isn't ane enum any more
4901 * config/tc-m68k.c: Added NO_RELOC definition.
4903 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4905 * Makefile.in: put header files before C source for TAGS; remove
4906 references to non-existent syscalls.h.
4908 * read.c, write.c subsegs.c: back out the .bss changes.
4910 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4912 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4916 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4918 * symbols.c (local_label_name): symbols now start with ^A.
4920 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4921 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4922 generate these sections. .align: will use NOP_OPCODE or 0
4923 for padding. This is just for being nice to the
4926 * expr.c (operand): changed to generate local label "\001L0"
4927 starting with a ^A so that it is recognized as a local label.
4929 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4931 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4932 i/o opcodes - inb, inw, outb and outw. string manipulation with
4933 att syntax - scmp, slod, smov, ssca, ssto.
4935 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4936 to just after .file .
4938 In obj_crawl_symbol_chain() where it tries to put the external
4939 symbols apart, with the condition:
4940 (!S_IS_DEFINED(symbolP) &&
4941 !S_IS_DEBUG(symbolP) &&
4942 !SF_GET_STATICS(symbolP))
4943 it was moving too many symbols out. So I switch it back to the
4945 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4947 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4948 so that we don't use the F_RELFLG which make the linker complain
4949 that somebody has stripped the relocation info.
4951 Also, the AIX ld program require that the relocation table
4952 is sorted by r_vaddr like the standard ATT assembler does.
4954 [he also changed the sizeof(struct ...)'s into the coff
4955 style FOOSZ macros. I'm not sure this is right, but I can't
4956 remember why. xoxorich.]
4958 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4960 * Makefile.in, configure.in, doc: use the doc. Build it, install
4963 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4965 * read.c: white space and comments only.
4967 * configure.in: use the new atof-ns32.c for ns32k.
4969 * write.c: comment change only.
4971 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4972 aren't yet integrated.
4974 * tc-i860.[hc]: blew off the dust. Something must still be done
4975 about conflicting relocation types.
4977 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4980 * tc-i960.c, tc-sparc.c: white space and comments only.
4982 * tc-a29k.h: delete duplicate macro definition.
4984 * new file atof-ns32k.c copied from hack's last unreleased gas.
4986 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4988 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4991 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4992 ChangeLog's prior to this are sketchy at best. I have logs.
4993 They just aren't ChangeLogs.
