1843 pass new argument for i, j and o cases.
1844 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1845 special handling when generating SVR4 PIC code.

2179 default is to assume production environment, and reject configs
2180 still being worked on. Mark Elf configurations (except sparc and
2181 i386) as developmental. Deleted cases matching some generic names
2182 in favor of more specific names. (E.g., when we get Alpha

2199 through inclusion of tc-hppa.h. Delete all forward declarations
2200 for functions only used within tc-hppa.c, likewise for structures,
2201 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2202 conditional code in a few small places.
2204 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

2207 conditional code -- try to group conditional code together
2208 into a few places. Make all functions and variables which
2209 are only used within tc-hppa.c static. PARAMize all functions.
2210 Add comments to functions. Delete unused functions, variables,
2211 #defines, etc. Delete unused members within structures. Delete
2212 ldil;ble hacks -- it is believed they were installed to work
2213 around old gas bugs. Avoid using mixed case for local
2214 functions, variables, and structures. Fix formatting problems
2215 not found by GNU-indent. Add FIXME notices for things which
2216 should be worked on the near future. Delete lots of old
2217 useless (1.36 PA-SOM) code.

2290 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2292 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2293 ELF, since the ELF object format does not have these type of
2294 relocations. Change the abort into as as_bad and return
2295 BFD_RELOC_NONE to silence compiler warnings.
2296 (md_assemble): Keep track of the instruction size. Allow white
2297 space between the $ and the constant for compatibility with older
2298 gases and other assemblers.
2299 (i386_operand): Skip spaces between $ and expression.

3292 Fri Jul 23 13:09:44 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3294 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
3295 are also magic, and have special default flag settings.
3296 (obj_elf_frob_symbol): Since the return value from this function
3297 isn't used, don't bother calling obj_elf_write_symbol_p, since it
3298 doesn't accomplish anything else.
3300 * config/tc-sparc.c (md_section_align): Round up section size only
3303 * symbols.c: Don't define DEBUG by default.

3309 * expr.c (expr): Don't let absolute_section override
3310 undefined_section for the return value.
3312 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3313 pseudo-op with a poc_handler field of NULL, ignore it and treat it
3314 as an instruction instead.
3315 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
3318 * config/tc-h8500.c (md_begin): Use a local variable when

3330 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3331 case to set obj_format=elf. Must go before i386-*-sysv* case that
3332 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3333 *-*-solaris case, and move to before *-sysv* case that wants to
3334 set obj_format to coff.

3360 * Extensive changes to permit symbols to contain any expression
3361 type and to delay the computation of the expression until the
3362 value is actually needed. This permits setting symbols to values
3363 calculated based on object code size. Expressions were changed to
3364 no longer be in a section, to stop the overloading of segment and
3365 expression type that previously occurred.
3367 * as.c (big_section, pass1_section, diff_section, absent_section):
3369 (expr_section): Added (used for dummy symbols which hold

3453 (previous_section, previous_subsection): New vars.
3454 (obj_elf_section): Save current place in case DWARF code wants us
3455 to pop back to it. Handle unquoted section name as well as quoted
3456 section name. Don't crash on invalid strings.
3457 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

3569 sy_resolved and sy_resolving single bit fields.
3570 * symbols.c (symbol_new): Don't initialize sy_forward field.

4732 dropping a space immediately following an identifier.
4733 * expr.c, write.c: Rewrote assert expressions to not use multiple
4734 lines; I don't think that can be done portably.
4735 * config/tc-mips.c (macro): Use $AT if target register is zero in
4736 load instruction, which it can be for a floating point load.

4810 prototypes for all static functions. Moved existing minimal
4811 debugging format support info #ifndef OBJ_ECOFF blocks.

4860 * make-gas.com: Find obstack.obj if it's not in the current
4862 * read.c (s_ignore): Don't declare is_end_of_line. It's
4863 redundant, and triggers a VMS gcc compiler bug.
4865 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4866 current segment as an argument. (Ignored in all cases but VMS.)
4867 All callers and definitions changed.

5196 * expr.c: Add "const" modifier to hex_value.
5197 * symbols.c: Finish conversion to S_* macros in the VMS only
5198 parts of the program. Add "const" modifier to
5199 md_[long,short]_jump_size. Remove declaration of const_flag
5200 (which will be declared in obj-vms.h).
5201 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5202 Fix arguments to VMS_write_object_file.
5203 * config-gas.com: New file. Script for VMS systems to set up the
5204 configuration to build gas for VMS, and create config.status.
5205 * make-gas.com: Redone to work with new scheme.
5206 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5208 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5209 will swap bytes if needed on a big endian system. Use throughout
5211 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5212 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5213 types of malformed stabs. Change parsing algorithm so that we are
5214 more certain of having all of the information that we need on hand.
5215 * obj-vms.c (final_forward_reference): New function, used to help
5216 resolve the data types of as many struct elements as possible
5217 when some part of the struct is not fully defined by the compiler.
5218 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5220 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5221 as symbols as well in the object file. Look for external functions
5222 that start with "__vt.", and turn them into variables, since the
5223 g++ compiler is incapable of doing this.
5224 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5226 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5227 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5228 have the name of the source file yet.

5234 SEG_DATA or SEG_E1 if needed.
5235 (s_lcomm): Likewise with bss_section.
5236 (s_fill): Use memset, not bzero.
5238 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5260 (big_section, reg_section, pass1_section, diff_section,
5261 absent_section, text_section, data_section, bss_section): If
5262 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5263 mapping to segT enum values.
5264 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5265 if these are used or defined, if BFD_ASSEMBLER.
5266 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5267 subseg_new split into two functions.
5268 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5270 * as.h (volatile): Don't define if already defined.
5271 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5273 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5274 declare with format attribute for -Wformat checking.
5276 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5278 * app.c, config/tc-*.c: Don't include read.h, since it is already
5281 * These are based on patches from Minh Tran-le
5282 <mtranle@paris.intellicorp.com>.
5283 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5284 obj_format coffbfd and gas_target i386coff for target.
5285 (i[34]86-*-isc*): New host (uses sysv).
5286 * config/i386aix.mt: Removed (no longer used).
5287 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5289 (LDFLAGS): Added, defined as -shlib.
5290 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5291 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5292 (DOT_LABEL_PREFIX): Define.
5293 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5294 name rather than L0\001.
5295 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5297 * symbols.c, symbols.h (local_bss_counter): Removed.

5306 (size_section): Restored sanity check.
5307 (do_relocs_for): Base section address on s_paddr rather than
5308 computing it. Adjust a29k R_IHIHALF special case to account for
5309 section paddr (used to require paddr to be zero). If there are no
5310 reclos, set s_relptr to 0. Set relocation size in object_headers.
5311 (fill_section): Always set s_vaddr here, removing
5312 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5313 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5314 Set STYP_INFO for .comment.

5318 H_{SET,GET}_* macros.
5319 (do_linenos_for): Set lineno size in object_headers.
5320 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5321 set s_vaddr here. If string_byte_count remains 4, set it back to
5322 0, and only write strings out if there are some. Call
5323 fill_section before do_relocs_for and do_linenos_for.
5324 (obj_coff_section): Handle optional quoted second argument giving
5325 section characteristics.
5326 (obj_coff_bss): Added to handle .bss.
5327 (obj_coff_ident): Added to handle .ident (puts string in .comment

5347 (do_scrub_next_char): For \", return " not '.
5348 (symbol_chars): Now const.
5350 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5351 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5353 * config/obj-coff.h: Don't use #elif.
5355 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5356 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5385 never set segment address for SEG_E2 (.bss) and don't write out
5386 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5387 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5388 definitions, and don't merge tags with non-tags. Check for .bf
5389 rather than just checking whether the second character is b and
5390 the third character is f.
5391 (obj_coff_val): gcc can generate values which we don't handle
5392 correctly; discard information for now, since it only affects the
5393 debugging information.

5395 (yank_symbols): Don't merge labels.
5396 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5667 * read.c (cons): If NO_RELOC is defined, use it.
5669 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5671 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5673 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5674 local labels to start with a .) and set REGISTER_PREFIX to %.
5675 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5693 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5694 sections starting from zero, rather than making them consecutive.
5695 This makes subsequent reloc calculations easier, esp if the object
5696 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5697 allocate lcomm in .data rather than in .bss. It seems that some
5698 tools can't cope with a non-zero sized bss before linkage.

5726 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5727 .word is < -32768 or > 32767. The -J flag causes the error to be
5728 ignored. This is to catch over-sized switches generated by gcc on
5729 systems which don't support the broken .word hack.
5730 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5731 write.c (fixup_segment): check for signed .word overflow if
5732 WARN_SIGNED_OVERFLOW_WORD.

5761 From Steve Chamberlain:
5762 Makefile.in: Handle m68*-*-coff*.

5776 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5778 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5781 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5783 * Makefile.in (LIBS): Include opcode library.

5810 * config/tc-m68k.c (init_table): Now const. Always include 68851
5811 data, so that "bc" is available to 68040 cache instructions.
5812 Added "tt0", "tt1", and 68ec030 variants.
5813 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5814 (enum _register): Added TT0, TT1.
5815 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5816 line number correctly in "internal error" messages. Don't print
5817 architecture-mismatch message for operand errors.

5842 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5843 has already been formatted (but may still contain %-characters).
5846 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5848 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5849 written with indirection on the last two operands, which can be
5850 either data or address registers. Added a new operand type 'r'
5851 which accepts either register type. Added '(' to notend stuff in
5852 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6163 * Makefile.in: added tooldir and program_prefix.
6165 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6167 * write.{c,h} (fix_new): Make these declarations consistent.
6169 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6171 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6174 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6176 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6178 * expr.c (operand): if can't work out what sort of operand it is,
6179 then look through FLT_CHARS for a hint.
6181 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6183 * Makefile.in, configure.in: removed traces of namesubdir,
6184 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6185 copyrights to '92, changed some from Cygnus to FSF.
6187 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6188 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6189 copyrights to '92, changed some from Cygnus to FSF.
6191 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6193 * expr.c: If an expression is single comma, then return with
6194 SEG_ABSENT rather than an error - since the sparc front end does
6195 really strange things with things like fbge,a
6197 * as.h: include bfd.h if using many sections
6198 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6199 local labels didn't work.
6200 * listing.c (list_symbol_table): don't core dump when there's no
6202 * write.c, write.h: call fix_new with the right number of args on
6204 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6207 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6209 * app.c: MRI compatibility - allow single quote to start a string.
6210 * as.c: fix typo recently introduced.
6211 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6212 * expr.c: Much rewriting, to accomodate MRI syntax for
6213 expressions. Also easier to read now.
6214 * listing.c: Put back defuns
6215 * read.c: modified to accept MRI syntax, put back listing pseudo
6216 ops so that an assembler built with NO_LISTING ignores list ops
6218 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6219 machine is a SPARC or a 29K.
6220 * config/obj-aout.c: added s_sect pseudo op
6221 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6222 fill in the timestamp.
6223 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6224 anymore, define all the relocs which the tc-<x> bit will use so we
6225 can translate from them to the coff types.
6226 * config/tc-a29k.c: reloc_type isn't ane enum any more
6227 * config/tc-m68k.c: Added NO_RELOC definition.
6229 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6231 * Makefile.in: put header files before C source for TAGS; remove
6232 references to non-existent syscalls.h.
6234 * read.c, write.c subsegs.c: back out the .bss changes.
6236 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6238 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6242 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6244 * symbols.c (local_label_name): symbols now start with ^A.
6246 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6247 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6248 generate these sections. .align: will use NOP_OPCODE or 0
6249 for padding. This is just for being nice to the
6252 * expr.c (operand): changed to generate local label "\001L0"
6253 starting with a ^A so that it is recognized as a local label.
6255 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6257 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6258 i/o opcodes - inb, inw, outb and outw. string manipulation with
6259 att syntax - scmp, slod, smov, ssca, ssto.
6261 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6262 to just after .file .
6264 In obj_crawl_symbol_chain() where it tries to put the external
6265 symbols apart, with the condition:
6266 (!S_IS_DEFINED(symbolP) &&
6267 !S_IS_DEBUG(symbolP) &&
6268 !SF_GET_STATICS(symbolP))
6269 it was moving too many symbols out. So I switch it back to the
6271 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6273 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6274 so that we don't use the F_RELFLG which make the linker complain
6275 that somebody has stripped the relocation info.
6277 Also, the AIX ld program require that the relocation table
6278 is sorted by r_vaddr like the standard ATT assembler does.
6280 [he also changed the sizeof(struct ...)'s into the coff
6281 style FOOSZ macros. I'm not sure this is right, but I can't
6282 remember why. xoxorich.]
6284 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6286 * Makefile.in, configure.in, doc: use the doc. Build it, install
6289 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6291 * read.c: white space and comments only.
6293 * configure.in: use the new atof-ns32.c for ns32k.
6295 * write.c: comment change only.
6297 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6298 aren't yet integrated.
6300 * tc-i860.[hc]: blew off the dust. Something must still be done
6301 about conflicting relocation types.
6303 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6306 * tc-i960.c, tc-sparc.c: white space and comments only.
6308 * tc-a29k.h: delete duplicate macro definition.
6310 * new file atof-ns32k.c copied from hack's last unreleased gas.
6312 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6314 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6317 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6318 ChangeLog's prior to this are sketchy at best. I have logs.
6319 They just aren't ChangeLogs.
6323 version-control: never
