1727 an example of marker relocations.
1728 * write.c (write_relocs): Instead of assuming size of a relocation
1729 is 4 bytes, pick up the size from relocation itself.

1759 pass new argument for i, j and o cases.

1981 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1982 the table, require that the one without bit 0x1000000 set come
1983 first. Require further that it be case 'b' or 'P'. The a29k
1984 opcode table already meets these constraints.
1985 (machine_ip): When handling case 'i' or 'A', make sure that the

2037 * write.c (write_relocs): For relocs that are pc_relative and
2038 pcrel_offset and not partial_inplace, adjust reloc->addend to

2094 for keeping or rejecting configurations still under development;
2095 default is to assume production environment, and reject configs
2096 still being worked on. Mark Elf configurations (except sparc and
2097 i386) as developmental. Deleted cases matching some generic names
2098 in favor of more specific names. (E.g., when we get Alpha

2115 through inclusion of tc-hppa.h. Delete all forward declarations
2116 for functions only used within tc-hppa.c, likewise for structures,
2117 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2118 conditional code in a few small places.
2120 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2121 structures, global variables, forward declarations together.

2123 conditional code -- try to group conditional code together
2124 into a few places. Make all functions and variables which
2125 are only used within tc-hppa.c static. PARAMize all functions.
2126 Add comments to functions. Delete unused functions, variables,
2127 #defines, etc. Delete unused members within structures. Delete
2128 ldil;ble hacks -- it is believed they were installed to work
2129 around old gas bugs. Avoid using mixed case for local
2130 functions, variables, and structures. Fix formatting problems
2131 not found by GNU-indent. Add FIXME notices for things which
2132 should be worked on the near future. Delete lots of old
2133 useless (1.36 PA-SOM) code.

2162 a multiple of the section alignment rather than always a
2165 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2206 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2208 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2209 ELF, since the ELF object format does not have these type of
2210 relocations. Change the abort into as as_bad and return
2211 BFD_RELOC_NONE to silence compiler warnings.
2212 (md_assemble): Keep track of the instruction size. Allow white
2213 space between the $ and the constant for compatibility with older
2214 gases and other assemblers.
2215 (i386_operand): Skip spaces between $ and expression.
2216 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

3276 * Extensive changes to permit symbols to contain any expression
3277 type and to delay the computation of the expression until the
3278 value is actually needed. This permits setting symbols to values
3279 calculated based on object code size. Expressions were changed to
3280 no longer be in a section, to stop the overloading of segment and
3281 expression type that previously occurred.

3485 sy_resolved and sy_resolving single bit fields.
3486 * symbols.c (symbol_new): Don't initialize sy_forward field.

4621 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4623 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4648 dropping a space immediately following an identifier.

4651 * config/tc-mips.c (macro): Use $AT if target register is zero in
4652 load instruction, which it can be for a floating point load.

4726 prototypes for all static functions. Moved existing minimal
4727 debugging format support info #ifndef OBJ_ECOFF blocks.

4776 * make-gas.com: Find obstack.obj if it's not in the current
4778 * read.c (s_ignore): Don't declare is_end_of_line. It's
4779 redundant, and triggers a VMS gcc compiler bug.
4781 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4782 current segment as an argument. (Ignored in all cases but VMS.)
4783 All callers and definitions changed.

5100 (operand): Treat zero byte as end-of-operand.
5102 * configure.in (per-target): Look for with_bfd_assembler option.
5103 For now, only accept "no", until the merge is done.
5105 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5106 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5107 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5108 * read.c: Finish conversion to S_* macros in the VMS only
5109 parts of the program. Add "const" modifier to hex_value.
5110 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5112 * expr.c: Add "const" modifier to hex_value.
5113 * symbols.c: Finish conversion to S_* macros in the VMS only
5114 parts of the program. Add "const" modifier to
5115 md_[long,short]_jump_size. Remove declaration of const_flag
5116 (which will be declared in obj-vms.h).
5117 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5118 Fix arguments to VMS_write_object_file.
5119 * config-gas.com: New file. Script for VMS systems to set up the
5120 configuration to build gas for VMS, and create config.status.

5136 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5137 as symbols as well in the object file. Look for external functions

5178 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5179 mapping to segT enum values.
5180 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5181 if these are used or defined, if BFD_ASSEMBLER.
5182 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5183 subseg_new split into two functions.
5184 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5186 * as.h (volatile): Don't define if already defined.
5187 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5189 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5190 declare with format attribute for -Wformat checking.
5192 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5194 * app.c, config/tc-*.c: Don't include read.h, since it is already
5197 * These are based on patches from Minh Tran-le
5198 <mtranle@paris.intellicorp.com>.
5199 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5200 obj_format coffbfd and gas_target i386coff for target.
5201 (i[34]86-*-isc*): New host (uses sysv).
5202 * config/i386aix.mt: Removed (no longer used).
5203 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5205 (LDFLAGS): Added, defined as -shlib.
5206 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5207 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5208 (DOT_LABEL_PREFIX): Define.
5209 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5210 name rather than L0\001.
5211 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5213 * symbols.c, symbols.h (local_bss_counter): Removed.
5214 * write.c (write_object_file): bss no longer uses
5215 local_bss_counter. Pass correct data and bss size to
5216 VMS_write_object_file.

5220 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
5221 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
5222 (size_section): Restored sanity check.
5223 (do_relocs_for): Base section address on s_paddr rather than
5224 computing it. Adjust a29k R_IHIHALF special case to account for
5225 section paddr (used to require paddr to be zero). If there are no
5226 reclos, set s_relptr to 0. Set relocation size in object_headers.
5227 (fill_section): Always set s_vaddr here, removing
5228 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5229 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5230 Set STYP_INFO for .comment.
5231 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5232 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5234 H_{SET,GET}_* macros.
5235 (do_linenos_for): Set lineno size in object_headers.
5236 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5237 set s_vaddr here. If string_byte_count remains 4, set it back to
5238 0, and only write strings out if there are some. Call
5239 fill_section before do_relocs_for and do_linenos_for.
5240 (obj_coff_section): Handle optional quoted second argument giving
5241 section characteristics.
5242 (obj_coff_bss): Added to handle .bss.
5243 (obj_coff_ident): Added to handle .ident (puts string in .comment
5245 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5246 (fixup_mdeps): Change to segment. Call frag_wane after
5248 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5249 adjustment (already happened only for common symbols, but this is
5251 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

5262 * app.c (app_push): Use memcpy, not bcopy.
5263 (do_scrub_next_char): For \", return " not '.
5264 (symbol_chars): Now const.
5266 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5267 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5269 * config/obj-coff.h: Don't use #elif.
5271 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5272 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5274 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5298 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5299 using ZERO_BASED_SEGMENTS.
5300 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5301 never set segment address for SEG_E2 (.bss) and don't write out
5302 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5303 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5304 definitions, and don't merge tags with non-tags. Check for .bf
5305 rather than just checking whether the second character is b and
5306 the third character is f.
5307 (obj_coff_val): gcc can generate values which we don't handle
5308 correctly; discard information for now, since it only affects the
5309 debugging information.
5310 (tag_find_or_name): Don't insert tags in the symbol table.
5311 (yank_symbols): Don't merge labels.
5312 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5315 (obj_coff_section): Accept and ignore a trailing quoted string, as
5316 used in AT&T i386 syntax.
5317 (fixup_segment): Take segment as argument. On the i386, adjust PC
5318 relative addends by the segment vaddr.
5319 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
5320 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

5457 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5458 could be doing emulation.
5460 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5463 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5492 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5494 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5495 constant will not fit in an immediate field.
5496 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
5498 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

5531 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5533 * Support for i386-sysv.
5534 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5538 (fill_section): Don't set STYP_NOLOAD for .bss section.
5539 (fixup_segment): 386 uses strange common symbol format.

5558 * tc-m68k.c (get_num): make it work for all segments, not just the
5561 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5563 * configure.in: recognize i386-*-bsd emulation.

5572 * tc-z8k.c: lots of bug fixes
5574 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5576 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5577 #elif, since it is not supported by old compilers.
5578 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5579 couple of expressions in tc-m68k.c.
5581 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5583 * read.c (cons): If NO_RELOC is defined, use it.
5585 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5587 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5589 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5590 local labels to start with a .) and set REGISTER_PREFIX to %.
5591 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5593 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
5595 * messages.c: Comment changes.
5597 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

5600 * messages.c: If __STDC__ is not defined, define NO_STDARG.
5602 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
5604 * listing.c (debugging_pseudo): Add stabs and stabn as things to
5607 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5609 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5610 sections starting from zero, rather than making them consecutive.
5611 This makes subsequent reloc calculations easier, esp if the object
5612 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5613 allocate lcomm in .data rather than in .bss. It seems that some
5614 tools can't cope with a non-zero sized bss before linkage.
5616 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5618 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5619 throughout. That enum no longer means what we thought it meant.
5621 * tc-m68k.c (md_assemble, md_parse_option): Handle new
5622 "-mno-688[58]1" options.
5624 * tc-m68k.c: Added CPU32 support.
5626 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)

5632 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
5633 Change LIBDEPS dependence to LIBS.
5635 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5637 * Makefile.in (install): if $(tooldir) exists, install as in
5640 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5642 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5643 .word is < -32768 or > 32767. The -J flag causes the error to be
5644 ignored. This is to catch over-sized switches generated by gcc on
5645 systems which don't support the broken .word hack.
5646 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5647 write.c (fixup_segment): check for signed .word overflow if
5648 WARN_SIGNED_OVERFLOW_WORD.
5650 * write.c (fixup_segment): fixed missing parens in expression
5651 checking for byte or word overflow.
5653 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
5654 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
5655 WARN_SIGNED_OVERFLOW_WORD.

6135 machine is a SPARC or a 29K.
6136 * config/obj-aout.c: added s_sect pseudo op
6137 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6138 fill in the timestamp.
6139 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6140 anymore, define all the relocs which the tc-<x> bit will use so we

6143 * config/tc-m68k.c: Added NO_RELOC definition.

6160 * symbols.c (local_label_name): symbols now start with ^A.
6162 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6163 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6164 generate these sections. .align: will use NOP_OPCODE or 0
6165 for padding. This is just for being nice to the
6168 * expr.c (operand): changed to generate local label "\001L0"
6169 starting with a ^A so that it is recognized as a local label.
6171 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6173 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6174 i/o opcodes - inb, inw, outb and outw. string manipulation with
6175 att syntax - scmp, slod, smov, ssca, ssto.
6177 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6178 to just after .file .
6180 In obj_crawl_symbol_chain() where it tries to put the external
6181 symbols apart, with the condition:
6182 (!S_IS_DEFINED(symbolP) &&
6183 !S_IS_DEBUG(symbolP) &&
6184 !SF_GET_STATICS(symbolP))
6185 it was moving too many symbols out. So I switch it back to the
6187 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6189 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6190 so that we don't use the F_RELFLG which make the linker complain
6191 that somebody has stripped the relocation info.
6193 Also, the AIX ld program require that the relocation table
6194 is sorted by r_vaddr like the standard ATT assembler does.
6196 [he also changed the sizeof(struct ...)'s into the coff
6197 style FOOSZ macros. I'm not sure this is right, but I can't
6198 remember why. xoxorich.]

6202 * Makefile.in, configure.in, doc: use the doc. Build it, install
6205 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6207 * read.c: white space and comments only.
6209 * configure.in: use the new atof-ns32.c for ns32k.
6211 * write.c: comment change only.
6213 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6214 aren't yet integrated.
6216 * tc-i860.[hc]: blew off the dust. Something must still be done
6217 about conflicting relocation types.
6219 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6222 * tc-i960.c, tc-sparc.c: white space and comments only.
6224 * tc-a29k.h: delete duplicate macro definition.
6226 * new file atof-ns32k.c copied from hack's last unreleased gas.
6228 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6230 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6233 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6234 ChangeLog's prior to this are sketchy at best. I have logs.
6235 They just aren't ChangeLogs.
