1838 pass new argument for i, j and o cases.
1839 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2060 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2061 the table, require that the one without bit 0x1000000 set come

2173 for keeping or rejecting configurations still under development;
2174 default is to assume production environment, and reject configs
2175 still being worked on. Mark Elf configurations (except sparc and
2176 i386) as developmental. Deleted cases matching some generic names
2177 in favor of more specific names. (E.g., when we get Alpha

2194 through inclusion of tc-hppa.h. Delete all forward declarations
2195 for functions only used within tc-hppa.c, likewise for structures,
2196 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2197 conditional code in a few small places.
2199 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2200 structures, global variables, forward declarations together.

2202 conditional code -- try to group conditional code together
2203 into a few places. Make all functions and variables which
2204 are only used within tc-hppa.c static. PARAMize all functions.
2205 Add comments to functions. Delete unused functions, variables,
2206 #defines, etc. Delete unused members within structures. Delete
2207 ldil;ble hacks -- it is believed they were installed to work
2208 around old gas bugs. Avoid using mixed case for local
2209 functions, variables, and structures. Fix formatting problems
2210 not found by GNU-indent. Add FIXME notices for things which
2211 should be worked on the near future. Delete lots of old
2212 useless (1.36 PA-SOM) code.

2285 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2287 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2288 ELF, since the ELF object format does not have these type of
2289 relocations. Change the abort into as as_bad and return
2290 BFD_RELOC_NONE to silence compiler warnings.
2291 (md_assemble): Keep track of the instruction size. Allow white
2292 space between the $ and the constant for compatibility with older
2293 gases and other assemblers.
2294 (i386_operand): Skip spaces between $ and expression.

3287 Fri Jul 23 13:09:44 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3289 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
3290 are also magic, and have special default flag settings.
3291 (obj_elf_frob_symbol): Since the return value from this function
3292 isn't used, don't bother calling obj_elf_write_symbol_p, since it
3293 doesn't accomplish anything else.

3305 undefined_section for the return value.
3307 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3308 pseudo-op with a poc_handler field of NULL, ignore it and treat it

3325 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3326 case to set obj_format=elf. Must go before i386-*-sysv* case that
3327 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3328 *-*-solaris case, and move to before *-sysv* case that wants to

3355 * Extensive changes to permit symbols to contain any expression
3356 type and to delay the computation of the expression until the
3357 value is actually needed. This permits setting symbols to values
3358 calculated based on object code size. Expressions were changed to
3359 no longer be in a section, to stop the overloading of segment and
3360 expression type that previously occurred.
3362 * as.c (big_section, pass1_section, diff_section, absent_section):
3364 (expr_section): Added (used for dummy symbols which hold

3448 (previous_section, previous_subsection): New vars.
3449 (obj_elf_section): Save current place in case DWARF code wants us
3450 to pop back to it. Handle unquoted section name as well as quoted
3451 section name. Don't crash on invalid strings.
3452 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3455 * config/obj-elf.h: Don't include struc-symbol.h.

3564 sy_resolved and sy_resolving single bit fields.
3565 * symbols.c (symbol_new): Don't initialize sy_forward field.

4727 dropping a space immediately following an identifier.
4728 * expr.c, write.c: Rewrote assert expressions to not use multiple
4729 lines; I don't think that can be done portably.
4730 * config/tc-mips.c (macro): Use $AT if target register is zero in
4731 load instruction, which it can be for a floating point load.

4805 prototypes for all static functions. Moved existing minimal
4806 debugging format support info #ifndef OBJ_ECOFF blocks.

4855 * make-gas.com: Find obstack.obj if it's not in the current
4857 * read.c (s_ignore): Don't declare is_end_of_line. It's
4858 redundant, and triggers a VMS gcc compiler bug.
4860 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4861 current segment as an argument. (Ignored in all cases but VMS.)
4862 All callers and definitions changed.

5192 * symbols.c: Finish conversion to S_* macros in the VMS only
5193 parts of the program. Add "const" modifier to
5194 md_[long,short]_jump_size. Remove declaration of const_flag
5195 (which will be declared in obj-vms.h).
5196 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5197 Fix arguments to VMS_write_object_file.
5198 * config-gas.com: New file. Script for VMS systems to set up the
5199 configuration to build gas for VMS, and create config.status.
5200 * make-gas.com: Redone to work with new scheme.
5201 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5203 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5204 will swap bytes if needed on a big endian system. Use throughout
5206 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5207 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5208 types of malformed stabs. Change parsing algorithm so that we are
5209 more certain of having all of the information that we need on hand.
5210 * obj-vms.c (final_forward_reference): New function, used to help
5211 resolve the data types of as many struct elements as possible
5212 when some part of the struct is not fully defined by the compiler.
5213 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5215 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5216 as symbols as well in the object file. Look for external functions
5217 that start with "__vt.", and turn them into variables, since the
5218 g++ compiler is incapable of doing this.
5219 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5221 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5222 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5223 have the name of the source file yet.

5229 SEG_DATA or SEG_E1 if needed.
5230 (s_lcomm): Likewise with bss_section.
5231 (s_fill): Use memset, not bzero.
5233 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5255 (big_section, reg_section, pass1_section, diff_section,
5256 absent_section, text_section, data_section, bss_section): If
5257 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5258 mapping to segT enum values.
5259 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5260 if these are used or defined, if BFD_ASSEMBLER.
5261 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5262 subseg_new split into two functions.
5263 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5265 * as.h (volatile): Don't define if already defined.
5266 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5268 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5269 declare with format attribute for -Wformat checking.
5271 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5273 * app.c, config/tc-*.c: Don't include read.h, since it is already
5276 * These are based on patches from Minh Tran-le
5277 <mtranle@paris.intellicorp.com>.
5278 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5279 obj_format coffbfd and gas_target i386coff for target.
5280 (i[34]86-*-isc*): New host (uses sysv).
5281 * config/i386aix.mt: Removed (no longer used).
5282 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5284 (LDFLAGS): Added, defined as -shlib.
5285 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5286 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5287 (DOT_LABEL_PREFIX): Define.
5288 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5289 name rather than L0\001.
5290 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5292 * symbols.c, symbols.h (local_bss_counter): Removed.

5301 (size_section): Restored sanity check.
5302 (do_relocs_for): Base section address on s_paddr rather than
5303 computing it. Adjust a29k R_IHIHALF special case to account for
5304 section paddr (used to require paddr to be zero). If there are no
5305 reclos, set s_relptr to 0. Set relocation size in object_headers.
5306 (fill_section): Always set s_vaddr here, removing
5307 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5308 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5309 Set STYP_INFO for .comment.

5313 H_{SET,GET}_* macros.
5314 (do_linenos_for): Set lineno size in object_headers.
5315 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5316 set s_vaddr here. If string_byte_count remains 4, set it back to
5317 0, and only write strings out if there are some. Call
5318 fill_section before do_relocs_for and do_linenos_for.
5319 (obj_coff_section): Handle optional quoted second argument giving
5320 section characteristics.
5321 (obj_coff_bss): Added to handle .bss.
5322 (obj_coff_ident): Added to handle .ident (puts string in .comment

5342 (do_scrub_next_char): For \", return " not '.
5343 (symbol_chars): Now const.
5345 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5346 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5348 * config/obj-coff.h: Don't use #elif.
5350 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5351 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5380 never set segment address for SEG_E2 (.bss) and don't write out
5381 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5382 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5383 definitions, and don't merge tags with non-tags. Check for .bf
5384 rather than just checking whether the second character is b and
5385 the third character is f.
5386 (obj_coff_val): gcc can generate values which we don't handle
5387 correctly; discard information for now, since it only affects the
5388 debugging information.

5390 (yank_symbols): Don't merge labels.
5391 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5666 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5668 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5669 local labels to start with a .) and set REGISTER_PREFIX to %.
5670 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5688 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5689 sections starting from zero, rather than making them consecutive.
5690 This makes subsequent reloc calculations easier, esp if the object
5691 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5692 allocate lcomm in .data rather than in .bss. It seems that some
5693 tools can't cope with a non-zero sized bss before linkage.
5695 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5697 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5719 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5721 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5722 .word is < -32768 or > 32767. The -J flag causes the error to be
5723 ignored. This is to catch over-sized switches generated by gcc on
5724 systems which don't support the broken .word hack.
5725 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5726 write.c (fixup_segment): check for signed .word overflow if
5727 WARN_SIGNED_OVERFLOW_WORD.

5756 From Steve Chamberlain:
5757 Makefile.in: Handle m68*-*-coff*.
5758 read.c, read.h: add mult argument to s_space
5760 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

5771 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5773 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5776 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

5805 * config/tc-m68k.c (init_table): Now const. Always include 68851
5806 data, so that "bc" is available to 68040 cache instructions.
5807 Added "tt0", "tt1", and 68ec030 variants.
5808 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5809 (enum _register): Added TT0, TT1.
5810 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5811 line number correctly in "internal error" messages. Don't print
5812 architecture-mismatch message for operand errors.

5837 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5838 has already been formatted (but may still contain %-characters).
5841 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5843 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5844 written with indirection on the last two operands, which can be
5845 either data or address registers. Added a new operand type 'r'
5846 which accepts either register type. Added '(' to notend stuff in
5847 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6162 * write.{c,h} (fix_new): Make these declarations consistent.
6164 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6166 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6169 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6171 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6173 * expr.c (operand): if can't work out what sort of operand it is,
6174 then look through FLT_CHARS for a hint.
6176 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6178 * Makefile.in, configure.in: removed traces of namesubdir,
6179 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6180 copyrights to '92, changed some from Cygnus to FSF.
6182 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6183 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6184 copyrights to '92, changed some from Cygnus to FSF.
6186 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6188 * expr.c: If an expression is single comma, then return with
6189 SEG_ABSENT rather than an error - since the sparc front end does
6190 really strange things with things like fbge,a
6192 * as.h: include bfd.h if using many sections
6193 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6194 local labels didn't work.
6195 * listing.c (list_symbol_table): don't core dump when there's no
6197 * write.c, write.h: call fix_new with the right number of args on
6199 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6202 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6204 * app.c: MRI compatibility - allow single quote to start a string.
6205 * as.c: fix typo recently introduced.
6206 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6207 * expr.c: Much rewriting, to accomodate MRI syntax for
6208 expressions. Also easier to read now.
6209 * listing.c: Put back defuns
6210 * read.c: modified to accept MRI syntax, put back listing pseudo
6211 ops so that an assembler built with NO_LISTING ignores list ops
6213 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6214 machine is a SPARC or a 29K.
6215 * config/obj-aout.c: added s_sect pseudo op
6216 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6217 fill in the timestamp.
6218 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6219 anymore, define all the relocs which the tc-<x> bit will use so we
6220 can translate from them to the coff types.
6221 * config/tc-a29k.c: reloc_type isn't ane enum any more
6222 * config/tc-m68k.c: Added NO_RELOC definition.
6224 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6226 * Makefile.in: put header files before C source for TAGS; remove
6227 references to non-existent syscalls.h.
6229 * read.c, write.c subsegs.c: back out the .bss changes.
6231 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6233 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6237 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6239 * symbols.c (local_label_name): symbols now start with ^A.
6241 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6242 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6243 generate these sections. .align: will use NOP_OPCODE or 0
6244 for padding. This is just for being nice to the
6247 * expr.c (operand): changed to generate local label "\001L0"
6248 starting with a ^A so that it is recognized as a local label.
6250 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6252 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6253 i/o opcodes - inb, inw, outb and outw. string manipulation with
6254 att syntax - scmp, slod, smov, ssca, ssto.
6256 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6257 to just after .file .
6259 In obj_crawl_symbol_chain() where it tries to put the external
6260 symbols apart, with the condition:
6261 (!S_IS_DEFINED(symbolP) &&
6262 !S_IS_DEBUG(symbolP) &&
6263 !SF_GET_STATICS(symbolP))
6264 it was moving too many symbols out. So I switch it back to the
6266 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6268 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6269 so that we don't use the F_RELFLG which make the linker complain
6270 that somebody has stripped the relocation info.
6272 Also, the AIX ld program require that the relocation table
6273 is sorted by r_vaddr like the standard ATT assembler does.
6275 [he also changed the sizeof(struct ...)'s into the coff
6276 style FOOSZ macros. I'm not sure this is right, but I can't
6277 remember why. xoxorich.]
6279 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6281 * Makefile.in, configure.in, doc: use the doc. Build it, install
6284 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6286 * read.c: white space and comments only.
6288 * configure.in: use the new atof-ns32.c for ns32k.
6290 * write.c: comment change only.
6292 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6293 aren't yet integrated.
6295 * tc-i860.[hc]: blew off the dust. Something must still be done
6296 about conflicting relocation types.
6298 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6301 * tc-i960.c, tc-sparc.c: white space and comments only.
6303 * tc-a29k.h: delete duplicate macro definition.
6305 * new file atof-ns32k.c copied from hack's last unreleased gas.
6307 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6309 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6312 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6313 ChangeLog's prior to this are sketchy at best. I have logs.
6314 They just aren't ChangeLogs.
6318 version-control: never
