1355 pass new argument for i, j and o cases.
1356 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

1577 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1578 the table, require that the one without bit 0x1000000 set come

1690 for keeping or rejecting configurations still under development;
1691 default is to assume production environment, and reject configs
1692 still being worked on. Mark Elf configurations (except sparc and
1693 i386) as developmental. Deleted cases matching some generic names
1694 in favor of more specific names. (E.g., when we get Alpha

1711 through inclusion of tc-hppa.h. Delete all forward declarations
1712 for functions only used within tc-hppa.c, likewise for structures,
1713 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1714 conditional code in a few small places.
1716 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1717 structures, global variables, forward declarations together.

1719 conditional code -- try to group conditional code together
1720 into a few places. Make all functions and variables which
1721 are only used within tc-hppa.c static. PARAMize all functions.
1722 Add comments to functions. Delete unused functions, variables,
1723 #defines, etc. Delete unused members within structures. Delete
1724 ldil;ble hacks -- it is believed they were installed to work
1725 around old gas bugs. Avoid using mixed case for local
1726 functions, variables, and structures. Fix formatting problems
1727 not found by GNU-indent. Add FIXME notices for things which
1728 should be worked on the near future. Delete lots of old
1729 useless (1.36 PA-SOM) code.

1802 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1804 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1805 ELF, since the ELF object format does not have these type of
1806 relocations. Change the abort into as as_bad and return
1807 BFD_RELOC_NONE to silence compiler warnings.
1808 (md_assemble): Keep track of the instruction size. Allow white
1809 space between the $ and the constant for compatibility with older
1810 gases and other assemblers.
1811 (i386_operand): Skip spaces between $ and expression.

2808 (obj_elf_frob_symbol): Since the return value from this function
2809 isn't used, don't bother calling obj_elf_write_symbol_p, since it
2810 doesn't accomplish anything else.
2812 * config/tc-sparc.c (md_section_align): Round up section size only
2815 * symbols.c: Don't define DEBUG by default.

2822 undefined_section for the return value.
2824 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
2825 pseudo-op with a poc_handler field of NULL, ignore it and treat it
2826 as an instruction instead.

2842 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
2843 case to set obj_format=elf. Must go before i386-*-sysv* case that
2844 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
2845 *-*-solaris case, and move to before *-sysv* case that wants to
2846 set obj_format to coff.

2872 * Extensive changes to permit symbols to contain any expression
2873 type and to delay the computation of the expression until the
2874 value is actually needed. This permits setting symbols to values
2875 calculated based on object code size. Expressions were changed to
2876 no longer be in a section, to stop the overloading of segment and
2877 expression type that previously occurred.
2879 * as.c (big_section, pass1_section, diff_section, absent_section):
2881 (expr_section): Added (used for dummy symbols which hold

2965 (previous_section, previous_subsection): New vars.
2966 (obj_elf_section): Save current place in case DWARF code wants us
2967 to pop back to it. Handle unquoted section name as well as quoted
2968 section name. Don't crash on invalid strings.
2969 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
2972 * config/obj-elf.h: Don't include struc-symbol.h.

3081 sy_resolved and sy_resolving single bit fields.
3082 * symbols.c (symbol_new): Don't initialize sy_forward field.

4244 dropping a space immediately following an identifier.
4245 * expr.c, write.c: Rewrote assert expressions to not use multiple
4246 lines; I don't think that can be done portably.
4247 * config/tc-mips.c (macro): Use $AT if target register is zero in
4248 load instruction, which it can be for a floating point load.

4322 prototypes for all static functions. Moved existing minimal
4323 debugging format support info #ifndef OBJ_ECOFF blocks.

4374 * read.c (s_ignore): Don't declare is_end_of_line. It's
4375 redundant, and triggers a VMS gcc compiler bug.
4377 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4378 current segment as an argument. (Ignored in all cases but VMS.)
4379 All callers and definitions changed.

4715 * config-gas.com: New file. Script for VMS systems to set up the
4716 configuration to build gas for VMS, and create config.status.
4717 * make-gas.com: Redone to work with new scheme.
4718 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4720 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4721 will swap bytes if needed on a big endian system. Use throughout
4723 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4724 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4725 types of malformed stabs. Change parsing algorithm so that we are
4726 more certain of having all of the information that we need on hand.
4727 * obj-vms.c (final_forward_reference): New function, used to help
4728 resolve the data types of as many struct elements as possible
4729 when some part of the struct is not fully defined by the compiler.
4730 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4732 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4733 as symbols as well in the object file. Look for external functions
4734 that start with "__vt.", and turn them into variables, since the
4735 g++ compiler is incapable of doing this.
4736 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4738 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4739 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4740 have the name of the source file yet.

4746 SEG_DATA or SEG_E1 if needed.
4747 (s_lcomm): Likewise with bss_section.
4748 (s_fill): Use memset, not bzero.
4750 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4774 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4775 mapping to segT enum values.
4776 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4777 if these are used or defined, if BFD_ASSEMBLER.
4778 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4779 subseg_new split into two functions.
4780 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4782 * as.h (volatile): Don't define if already defined.
4783 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4785 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4786 declare with format attribute for -Wformat checking.
4788 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4790 * app.c, config/tc-*.c: Don't include read.h, since it is already
4793 * These are based on patches from Minh Tran-le
4794 <mtranle@paris.intellicorp.com>.
4795 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4796 obj_format coffbfd and gas_target i386coff for target.
4797 (i[34]86-*-isc*): New host (uses sysv).
4798 * config/i386aix.mt: Removed (no longer used).
4799 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4801 (LDFLAGS): Added, defined as -shlib.
4802 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4803 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4804 (DOT_LABEL_PREFIX): Define.
4805 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4806 name rather than L0\001.
4807 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4809 * symbols.c, symbols.h (local_bss_counter): Removed.

4818 (size_section): Restored sanity check.
4819 (do_relocs_for): Base section address on s_paddr rather than
4820 computing it. Adjust a29k R_IHIHALF special case to account for
4821 section paddr (used to require paddr to be zero). If there are no
4822 reclos, set s_relptr to 0. Set relocation size in object_headers.
4823 (fill_section): Always set s_vaddr here, removing
4824 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4825 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4826 Set STYP_INFO for .comment.

4830 H_{SET,GET}_* macros.
4831 (do_linenos_for): Set lineno size in object_headers.
4832 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4833 set s_vaddr here. If string_byte_count remains 4, set it back to
4834 0, and only write strings out if there are some. Call
4835 fill_section before do_relocs_for and do_linenos_for.
4836 (obj_coff_section): Handle optional quoted second argument giving
4837 section characteristics.
4838 (obj_coff_bss): Added to handle .bss.

4859 (do_scrub_next_char): For \", return " not '.
4860 (symbol_chars): Now const.
4862 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4863 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4865 * config/obj-coff.h: Don't use #elif.
4867 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4868 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

4897 never set segment address for SEG_E2 (.bss) and don't write out
4898 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4899 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4900 definitions, and don't merge tags with non-tags. Check for .bf
4901 rather than just checking whether the second character is b and
4902 the third character is f.
4903 (obj_coff_val): gcc can generate values which we don't handle
4904 correctly; discard information for now, since it only affects the
4905 debugging information.

4907 (yank_symbols): Don't merge labels.
4908 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5205 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5206 sections starting from zero, rather than making them consecutive.
5207 This makes subsequent reloc calculations easier, esp if the object
5208 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5209 allocate lcomm in .data rather than in .bss. It seems that some
5210 tools can't cope with a non-zero sized bss before linkage.
5212 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5214 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5236 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5238 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5239 .word is < -32768 or > 32767. The -J flag causes the error to be
5240 ignored. This is to catch over-sized switches generated by gcc on
5241 systems which don't support the broken .word hack.
5242 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5243 write.c (fixup_segment): check for signed .word overflow if
5244 WARN_SIGNED_OVERFLOW_WORD.

5273 From Steve Chamberlain:
5274 Makefile.in: Handle m68*-*-coff*.
5275 read.c, read.h: add mult argument to s_space
5277 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

5288 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5290 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5293 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5295 * Makefile.in (LIBS): Include opcode library.

5322 * config/tc-m68k.c (init_table): Now const. Always include 68851
5323 data, so that "bc" is available to 68040 cache instructions.
5324 Added "tt0", "tt1", and 68ec030 variants.
5325 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5326 (enum _register): Added TT0, TT1.
5327 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5328 line number correctly in "internal error" messages. Don't print
5329 architecture-mismatch message for operand errors.

5354 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5355 has already been formatted (but may still contain %-characters).
5358 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5360 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5361 written with indirection on the last two operands, which can be
5362 either data or address registers. Added a new operand type 'r'
5363 which accepts either register type. Added '(' to notend stuff in
5364 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5688 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5690 * expr.c (operand): if can't work out what sort of operand it is,
5691 then look through FLT_CHARS for a hint.
5693 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5695 * Makefile.in, configure.in: removed traces of namesubdir,
5696 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5697 copyrights to '92, changed some from Cygnus to FSF.
5699 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5700 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5701 copyrights to '92, changed some from Cygnus to FSF.
5703 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5705 * expr.c: If an expression is single comma, then return with
5706 SEG_ABSENT rather than an error - since the sparc front end does
5707 really strange things with things like fbge,a
5709 * as.h: include bfd.h if using many sections
5710 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5711 local labels didn't work.
5712 * listing.c (list_symbol_table): don't core dump when there's no
5714 * write.c, write.h: call fix_new with the right number of args on
5716 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5719 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5721 * app.c: MRI compatibility - allow single quote to start a string.
5722 * as.c: fix typo recently introduced.
5723 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5724 * expr.c: Much rewriting, to accomodate MRI syntax for
5725 expressions. Also easier to read now.
5726 * listing.c: Put back defuns
5727 * read.c: modified to accept MRI syntax, put back listing pseudo
5728 ops so that an assembler built with NO_LISTING ignores list ops
5730 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5731 machine is a SPARC or a 29K.
5732 * config/obj-aout.c: added s_sect pseudo op
5733 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5734 fill in the timestamp.
5735 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5736 anymore, define all the relocs which the tc-<x> bit will use so we
5737 can translate from them to the coff types.
5738 * config/tc-a29k.c: reloc_type isn't ane enum any more
5739 * config/tc-m68k.c: Added NO_RELOC definition.
5741 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5743 * Makefile.in: put header files before C source for TAGS; remove
5744 references to non-existent syscalls.h.
5746 * read.c, write.c subsegs.c: back out the .bss changes.
5748 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5750 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5754 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5756 * symbols.c (local_label_name): symbols now start with ^A.
5758 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5759 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5760 generate these sections. .align: will use NOP_OPCODE or 0
5761 for padding. This is just for being nice to the
5764 * expr.c (operand): changed to generate local label "\001L0"
5765 starting with a ^A so that it is recognized as a local label.
5767 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5769 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5770 i/o opcodes - inb, inw, outb and outw. string manipulation with
5771 att syntax - scmp, slod, smov, ssca, ssto.
5773 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5774 to just after .file .
5776 In obj_crawl_symbol_chain() where it tries to put the external
5777 symbols apart, with the condition:
5778 (!S_IS_DEFINED(symbolP) &&
5779 !S_IS_DEBUG(symbolP) &&
5780 !SF_GET_STATICS(symbolP))
5781 it was moving too many symbols out. So I switch it back to the
5783 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5785 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5786 so that we don't use the F_RELFLG which make the linker complain
5787 that somebody has stripped the relocation info.
5789 Also, the AIX ld program require that the relocation table
5790 is sorted by r_vaddr like the standard ATT assembler does.
5792 [he also changed the sizeof(struct ...)'s into the coff
5793 style FOOSZ macros. I'm not sure this is right, but I can't
5794 remember why. xoxorich.]
5796 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5798 * Makefile.in, configure.in, doc: use the doc. Build it, install
5801 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5803 * read.c: white space and comments only.
5805 * configure.in: use the new atof-ns32.c for ns32k.
5807 * write.c: comment change only.
5809 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5810 aren't yet integrated.
5812 * tc-i860.[hc]: blew off the dust. Something must still be done
5813 about conflicting relocation types.
5815 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5818 * tc-i960.c, tc-sparc.c: white space and comments only.
5820 * tc-a29k.h: delete duplicate macro definition.
5822 * new file atof-ns32k.c copied from hack's last unreleased gas.
5824 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5826 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5829 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5830 ChangeLog's prior to this are sketchy at best. I have logs.
5831 They just aren't ChangeLogs.
