1201 Delete dead code. Simplify.
1202 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
1203 applied are in range. Use bfd_put_32 rather than inserting each
1204 byte of the fixed instrution into the buffer ourselves.

1273 predefined register table.
1274 (pa_parse_number): Handle %rp in common register shortcut code.
1275 Consistently set return value to -1 for an error. Clean up error
1276 messages and only print them when "print_errors" is true. Handle
1277 empty string case like the HP assembler -- assume a value of
1280 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
1281 standard hpux include files to pick up various function decls.
1283 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in
1284 stdio.h. Delete bogus declaration of free. Get path to
1285 alloca-conf.h right.

1295 so GAS can attach unwind descriptor information to a BFD symbol.
1296 * config/tc-hppa.c (fix_new_hppa): If necessary attach unwind
1297 descriptor information to the BFD symbol.
1298 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",
1299 they are simply markers. Make R_HPPA_UNWIND_* handling OBJ_ELF

1316 of interest to the linker. ENTRY/EXIT relocations for SOM are
1317 an example of marker relocations.
1318 * write.c (write_relocs): Instead of assuming size of a relocation
1319 is 4 bytes, pick up the size from relocation itself.

1347 BFD_RELOC_MIPS_GPREL. Added new case a.
1348 (set_at, load_register, macro): Changed calls to macro_build to
1349 pass new argument for i, j and o cases.
1350 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1351 special handling when generating SVR4 PIC code.
1352 (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
1353 rather than hard coded constants.
1354 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

1372 Fix typo in space/subspace rework.
1373 (is_defined_subspace): Delete unused 2nd arg. All callers changed.
1375 * config/tc-hppa.c (pa_import): If currently in the text segment

1399 (FAKE_LABEL_NAME): New macro. Defines the default name used for
1401 * expr.c (make_expr_symbol): Delete DOT_LABEL_PREFIX code
1402 and instead simply use the string defined by FAKE_LABEL_NAME.
1403 (operand): Likewise.
1404 * read.c (s_stab_generic): Likewise.
1405 * config/tc-hppa.h (FAKE_LABEL_NAME): Define as L$0\001 so it's
1406 known to be a local label.
1407 * config/tc-i386.h (DOT_LABEL_PREFIX): Delete.
1408 (LOCAL_LABEL, FAKE_LABEL_NAME): Define.

1417 to control the use of space/subspace name aliases.
1418 (update_subspace): Accept space chain entry for containing space
1419 as a new parameter. All callers changed.
1420 (pa_get_label): Use current_space rather than pa_segment_to_space.

1423 (md_begin): Change into the (possibly modified) text_section.
1424 (pa_parse_space_stmt): Create a new segment/space if create_flag
1425 is true, and the space name is not one of the two predefined spaces.

1430 (pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES
1431 is true. When not using aliases, create a BFD section for each
1432 subspace encountered. When not using aliases replace the default
1433 text, data, and bss segments with new ones.

1571 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1572 the table, require that the one without bit 0x1000000 set come

1684 for keeping or rejecting configurations still under development;
1685 default is to assume production environment, and reject configs
1686 still being worked on. Mark Elf configurations (except sparc and
1687 i386) as developmental. Deleted cases matching some generic names
1688 in favor of more specific names. (E.g., when we get Alpha

1706 for functions only used within tc-hppa.c, likewise for structures,
1707 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1708 conditional code in a few small places.
1710 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1711 structures, global variables, forward declarations together.

1713 conditional code -- try to group conditional code together
1714 into a few places. Make all functions and variables which
1715 are only used within tc-hppa.c static. PARAMize all functions.
1716 Add comments to functions. Delete unused functions, variables,
1717 #defines, etc. Delete unused members within structures. Delete
1718 ldil;ble hacks -- it is believed they were installed to work
1719 around old gas bugs. Avoid using mixed case for local
1720 functions, variables, and structures. Fix formatting problems
1721 not found by GNU-indent. Add FIXME notices for things which
1722 should be worked on the near future. Delete lots of old
1723 useless (1.36 PA-SOM) code.

1796 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1798 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1799 ELF, since the ELF object format does not have these type of
1800 relocations. Change the abort into as as_bad and return
1801 BFD_RELOC_NONE to silence compiler warnings.
1802 (md_assemble): Keep track of the instruction size. Allow white
1803 space between the $ and the constant for compatibility with older
1804 gases and other assemblers.
1805 (i386_operand): Skip spaces between $ and expression.

2816 undefined_section for the return value.
2818 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
2819 pseudo-op with a poc_handler field of NULL, ignore it and treat it
2820 as an instruction instead.

2836 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
2837 case to set obj_format=elf. Must go before i386-*-sysv* case that
2838 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
2839 *-*-solaris case, and move to before *-sysv* case that wants to

2866 * Extensive changes to permit symbols to contain any expression
2867 type and to delay the computation of the expression until the
2868 value is actually needed. This permits setting symbols to values
2869 calculated based on object code size. Expressions were changed to
2870 no longer be in a section, to stop the overloading of segment and
2871 expression type that previously occurred.
2873 * as.c (big_section, pass1_section, diff_section, absent_section):
2875 (expr_section): Added (used for dummy symbols which hold

2959 (previous_section, previous_subsection): New vars.
2960 (obj_elf_section): Save current place in case DWARF code wants us
2961 to pop back to it. Handle unquoted section name as well as quoted
2962 section name. Don't crash on invalid strings.
2963 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

3075 sy_resolved and sy_resolving single bit fields.
3076 * symbols.c (symbol_new): Don't initialize sy_forward field.

4238 dropping a space immediately following an identifier.
4239 * expr.c, write.c: Rewrote assert expressions to not use multiple
4240 lines; I don't think that can be done portably.
4241 * config/tc-mips.c (macro): Use $AT if target register is zero in
4242 load instruction, which it can be for a floating point load.

4316 prototypes for all static functions. Moved existing minimal
4317 debugging format support info #ifndef OBJ_ECOFF blocks.

4368 * read.c (s_ignore): Don't declare is_end_of_line. It's
4369 redundant, and triggers a VMS gcc compiler bug.
4371 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4372 current segment as an argument. (Ignored in all cases but VMS.)

4715 will swap bytes if needed on a big endian system. Use throughout
4717 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4718 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4719 types of malformed stabs. Change parsing algorithm so that we are
4720 more certain of having all of the information that we need on hand.
4721 * obj-vms.c (final_forward_reference): New function, used to help
4722 resolve the data types of as many struct elements as possible
4723 when some part of the struct is not fully defined by the compiler.
4724 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4726 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4727 as symbols as well in the object file. Look for external functions
4728 that start with "__vt.", and turn them into variables, since the
4729 g++ compiler is incapable of doing this.
4730 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4732 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4733 * input-scrub.c (as_where): Fix bug where as would crash if we did not

4737 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4739 * read.c (s_data): Always use "data_section", since it'll map to
4740 SEG_DATA or SEG_E1 if needed.
4741 (s_lcomm): Likewise with bss_section.
4742 (s_fill): Use memset, not bzero.
4744 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4766 (big_section, reg_section, pass1_section, diff_section,
4767 absent_section, text_section, data_section, bss_section): If
4768 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4769 mapping to segT enum values.
4770 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4771 if these are used or defined, if BFD_ASSEMBLER.
4772 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4773 subseg_new split into two functions.
4774 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4776 * as.h (volatile): Don't define if already defined.
4777 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4779 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4780 declare with format attribute for -Wformat checking.
4782 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4784 * app.c, config/tc-*.c: Don't include read.h, since it is already
4787 * These are based on patches from Minh Tran-le
4788 <mtranle@paris.intellicorp.com>.
4789 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4790 obj_format coffbfd and gas_target i386coff for target.
4791 (i[34]86-*-isc*): New host (uses sysv).
4792 * config/i386aix.mt: Removed (no longer used).
4793 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4795 (LDFLAGS): Added, defined as -shlib.
4796 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4797 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4798 (DOT_LABEL_PREFIX): Define.
4799 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4800 name rather than L0\001.
4801 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4803 * symbols.c, symbols.h (local_bss_counter): Removed.

4812 (size_section): Restored sanity check.
4813 (do_relocs_for): Base section address on s_paddr rather than
4814 computing it. Adjust a29k R_IHIHALF special case to account for
4815 section paddr (used to require paddr to be zero). If there are no
4816 reclos, set s_relptr to 0. Set relocation size in object_headers.
4817 (fill_section): Always set s_vaddr here, removing
4818 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4819 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4820 Set STYP_INFO for .comment.

4824 H_{SET,GET}_* macros.
4825 (do_linenos_for): Set lineno size in object_headers.
4826 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4827 set s_vaddr here. If string_byte_count remains 4, set it back to
4828 0, and only write strings out if there are some. Call
4829 fill_section before do_relocs_for and do_linenos_for.
4830 (obj_coff_section): Handle optional quoted second argument giving
4831 section characteristics.
4832 (obj_coff_bss): Added to handle .bss.
4833 (obj_coff_ident): Added to handle .ident (puts string in .comment

4853 (do_scrub_next_char): For \", return " not '.
4854 (symbol_chars): Now const.
4856 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4857 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4859 * config/obj-coff.h: Don't use #elif.
4861 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4862 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

4891 never set segment address for SEG_E2 (.bss) and don't write out
4892 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4893 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4894 definitions, and don't merge tags with non-tags. Check for .bf
4895 rather than just checking whether the second character is b and
4896 the third character is f.
4897 (obj_coff_val): gcc can generate values which we don't handle
4898 correctly; discard information for now, since it only affects the
4899 debugging information.

4901 (yank_symbols): Don't merge labels.
4902 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5199 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5200 sections starting from zero, rather than making them consecutive.
5201 This makes subsequent reloc calculations easier, esp if the object
5202 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5203 allocate lcomm in .data rather than in .bss. It seems that some
5204 tools can't cope with a non-zero sized bss before linkage.
5206 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5208 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5209 throughout. That enum no longer means what we thought it meant.

5230 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5232 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5233 .word is < -32768 or > 32767. The -J flag causes the error to be
5234 ignored. This is to catch over-sized switches generated by gcc on
5235 systems which don't support the broken .word hack.
5236 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5237 write.c (fixup_segment): check for signed .word overflow if
5238 WARN_SIGNED_OVERFLOW_WORD.
5240 * write.c (fixup_segment): fixed missing parens in expression
5241 checking for byte or word overflow.

5267 From Steve Chamberlain:
5268 Makefile.in: Handle m68*-*-coff*.
5269 read.c, read.h: add mult argument to s_space
5271 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5272 Motorola and MIT syntax; gas can now assemble either type of

5282 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5284 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5287 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5289 * Makefile.in (LIBS): Include opcode library.

5316 * config/tc-m68k.c (init_table): Now const. Always include 68851
5317 data, so that "bc" is available to 68040 cache instructions.
5318 Added "tt0", "tt1", and 68ec030 variants.
5319 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5320 (enum _register): Added TT0, TT1.
5321 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5322 line number correctly in "internal error" messages. Don't print
5323 architecture-mismatch message for operand errors.
5325 From Colin Smith (colin@wrs.com):
5326 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

5348 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5349 has already been formatted (but may still contain %-characters).
5352 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5354 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5355 written with indirection on the last two operands, which can be
5356 either data or address registers. Added a new operand type 'r'
5357 which accepts either register type. Added '(' to notend stuff in
5358 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5689 * Makefile.in, configure.in: removed traces of namesubdir,
5690 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5691 copyrights to '92, changed some from Cygnus to FSF.
5693 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5694 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5695 copyrights to '92, changed some from Cygnus to FSF.
5697 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5699 * expr.c: If an expression is single comma, then return with
5700 SEG_ABSENT rather than an error - since the sparc front end does
5701 really strange things with things like fbge,a
5703 * as.h: include bfd.h if using many sections
5704 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5705 local labels didn't work.
5706 * listing.c (list_symbol_table): don't core dump when there's no
5708 * write.c, write.h: call fix_new with the right number of args on
5710 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5713 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5715 * app.c: MRI compatibility - allow single quote to start a string.
5716 * as.c: fix typo recently introduced.
5717 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5718 * expr.c: Much rewriting, to accomodate MRI syntax for
5719 expressions. Also easier to read now.
5720 * listing.c: Put back defuns
5721 * read.c: modified to accept MRI syntax, put back listing pseudo
5722 ops so that an assembler built with NO_LISTING ignores list ops
5724 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5725 machine is a SPARC or a 29K.
5726 * config/obj-aout.c: added s_sect pseudo op
5727 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5728 fill in the timestamp.
5729 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5730 anymore, define all the relocs which the tc-<x> bit will use so we
5731 can translate from them to the coff types.
5732 * config/tc-a29k.c: reloc_type isn't ane enum any more
5733 * config/tc-m68k.c: Added NO_RELOC definition.
5735 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5737 * Makefile.in: put header files before C source for TAGS; remove
5738 references to non-existent syscalls.h.
5740 * read.c, write.c subsegs.c: back out the .bss changes.
5742 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5744 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5748 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5750 * symbols.c (local_label_name): symbols now start with ^A.
5752 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5753 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5754 generate these sections. .align: will use NOP_OPCODE or 0
5755 for padding. This is just for being nice to the
5758 * expr.c (operand): changed to generate local label "\001L0"
5759 starting with a ^A so that it is recognized as a local label.
5761 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5763 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5764 i/o opcodes - inb, inw, outb and outw. string manipulation with
5765 att syntax - scmp, slod, smov, ssca, ssto.
5767 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5768 to just after .file .
5770 In obj_crawl_symbol_chain() where it tries to put the external
5771 symbols apart, with the condition:
5772 (!S_IS_DEFINED(symbolP) &&
5773 !S_IS_DEBUG(symbolP) &&
5774 !SF_GET_STATICS(symbolP))
5775 it was moving too many symbols out. So I switch it back to the
5777 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5779 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5780 so that we don't use the F_RELFLG which make the linker complain
5781 that somebody has stripped the relocation info.
5783 Also, the AIX ld program require that the relocation table
5784 is sorted by r_vaddr like the standard ATT assembler does.
5786 [he also changed the sizeof(struct ...)'s into the coff
5787 style FOOSZ macros. I'm not sure this is right, but I can't
5788 remember why. xoxorich.]
5790 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5792 * Makefile.in, configure.in, doc: use the doc. Build it, install
5795 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5797 * read.c: white space and comments only.
5799 * configure.in: use the new atof-ns32.c for ns32k.
5801 * write.c: comment change only.
5803 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5804 aren't yet integrated.
5806 * tc-i860.[hc]: blew off the dust. Something must still be done
5807 about conflicting relocation types.
5809 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5812 * tc-i960.c, tc-sparc.c: white space and comments only.
5814 * tc-a29k.h: delete duplicate macro definition.
5816 * new file atof-ns32k.c copied from hack's last unreleased gas.
5818 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5820 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5823 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5824 ChangeLog's prior to this are sketchy at best. I have logs.
5825 They just aren't ChangeLogs.
