1877 BFD_RELOC_MIPS_GPREL. Added new case a.
1878 (set_at, load_register, macro): Changed calls to macro_build to
1879 pass new argument for i, j and o cases.
1880 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1881 special handling when generating SVR4 PIC code.

2214 for keeping or rejecting configurations still under development;
2215 default is to assume production environment, and reject configs
2216 still being worked on. Mark Elf configurations (except sparc and
2217 i386) as developmental. Deleted cases matching some generic names
2218 in favor of more specific names. (E.g., when we get Alpha

2235 through inclusion of tc-hppa.h. Delete all forward declarations
2236 for functions only used within tc-hppa.c, likewise for structures,
2237 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2238 conditional code in a few small places.
2240 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

2243 conditional code -- try to group conditional code together
2244 into a few places. Make all functions and variables which
2245 are only used within tc-hppa.c static. PARAMize all functions.
2246 Add comments to functions. Delete unused functions, variables,
2247 #defines, etc. Delete unused members within structures. Delete
2248 ldil;ble hacks -- it is believed they were installed to work
2249 around old gas bugs. Avoid using mixed case for local
2250 functions, variables, and structures. Fix formatting problems
2251 not found by GNU-indent. Add FIXME notices for things which
2252 should be worked on the near future. Delete lots of old
2253 useless (1.36 PA-SOM) code.

2326 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2328 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2329 ELF, since the ELF object format does not have these type of
2330 relocations. Change the abort into as as_bad and return
2331 BFD_RELOC_NONE to silence compiler warnings.
2332 (md_assemble): Keep track of the instruction size. Allow white
2333 space between the $ and the constant for compatibility with older
2334 gases and other assemblers.
2335 (i386_operand): Skip spaces between $ and expression.

3284 * config/ho-sunos.h: remove some old function decls that conflict
3285 w/ ANSI, and which weren't needed anyway
3287 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3289 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

3331 are also magic, and have special default flag settings.
3332 (obj_elf_frob_symbol): Since the return value from this function
3333 isn't used, don't bother calling obj_elf_write_symbol_p, since it
3334 doesn't accomplish anything else.

3346 undefined_section for the return value.
3348 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3349 pseudo-op with a poc_handler field of NULL, ignore it and treat it
3350 as an instruction instead.

3366 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3367 case to set obj_format=elf. Must go before i386-*-sysv* case that
3368 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3369 *-*-solaris case, and move to before *-sysv* case that wants to
3370 set obj_format to coff.

3396 * Extensive changes to permit symbols to contain any expression
3397 type and to delay the computation of the expression until the
3398 value is actually needed. This permits setting symbols to values
3399 calculated based on object code size. Expressions were changed to
3400 no longer be in a section, to stop the overloading of segment and
3401 expression type that previously occurred.
3403 * as.c (big_section, pass1_section, diff_section, absent_section):
3405 (expr_section): Added (used for dummy symbols which hold

3489 (previous_section, previous_subsection): New vars.
3490 (obj_elf_section): Save current place in case DWARF code wants us
3491 to pop back to it. Handle unquoted section name as well as quoted
3492 section name. Don't crash on invalid strings.
3493 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

3605 sy_resolved and sy_resolving single bit fields.
3606 * symbols.c (symbol_new): Don't initialize sy_forward field.

4719 process relocs if there aren't any relocs to process. Avoids
4720 malloc/free bug on SCO too.

4768 dropping a space immediately following an identifier.
4769 * expr.c, write.c: Rewrote assert expressions to not use multiple
4770 lines; I don't think that can be done portably.
4771 * config/tc-mips.c (macro): Use $AT if target register is zero in
4772 load instruction, which it can be for a floating point load.

4898 * read.c (s_ignore): Don't declare is_end_of_line. It's
4899 redundant, and triggers a VMS gcc compiler bug.
4901 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4902 current segment as an argument. (Ignored in all cases but VMS.)
4903 All callers and definitions changed.

5195 offset field is set.
5197 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5199 * config/tc-sparc.c (architecture_requested, warn_on_bump,
5200 md_relax_table): Use default zero initialization.
5201 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5202 latter, instead of selecting with preprocessor conditionals.
5204 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5206 * configure.in: recognise all sparclite variants
5208 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5210 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
5211 accidentally changed to use subseg_change where it should have
5214 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5216 * expr.c (operand): If character other than comma or newline is a
5217 logical end-of-line character, use the newline case.
5218 From Eric Youngdale:
5219 (operand): Set X_add_number field for floating-point numbers.
5220 (operand): Treat zero byte as end-of-operand.
5222 * configure.in (per-target): Look for with_bfd_assembler option.
5223 For now, only accept "no", until the merge is done.
5225 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5226 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5227 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5228 * read.c: Finish conversion to S_* macros in the VMS only
5229 parts of the program. Add "const" modifier to hex_value.
5230 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5232 * expr.c: Add "const" modifier to hex_value.
5233 * symbols.c: Finish conversion to S_* macros in the VMS only
5234 parts of the program. Add "const" modifier to
5235 md_[long,short]_jump_size. Remove declaration of const_flag
5236 (which will be declared in obj-vms.h).
5237 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5238 Fix arguments to VMS_write_object_file.
5239 * config-gas.com: New file. Script for VMS systems to set up the
5240 configuration to build gas for VMS, and create config.status.
5241 * make-gas.com: Redone to work with new scheme.
5242 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5244 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5245 will swap bytes if needed on a big endian system. Use throughout
5247 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5248 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5249 types of malformed stabs. Change parsing algorithm so that we are
5250 more certain of having all of the information that we need on hand.
5251 * obj-vms.c (final_forward_reference): New function, used to help
5252 resolve the data types of as many struct elements as possible
5253 when some part of the struct is not fully defined by the compiler.
5254 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5256 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5257 as symbols as well in the object file. Look for external functions
5258 that start with "__vt.", and turn them into variables, since the
5259 g++ compiler is incapable of doing this.
5260 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5262 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5263 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5264 have the name of the source file yet.
5265 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5267 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5269 * read.c (s_data): Always use "data_section", since it'll map to
5270 SEG_DATA or SEG_E1 if needed.
5271 (s_lcomm): Likewise with bss_section.
5272 (s_fill): Use memset, not bzero.
5274 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
5276 * read.c: Deleted some code under "#ifdef DONTDEF" that was for
5277 handling GDB symbol table data.

5290 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5291 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
5292 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
5293 otherwise, use seg_name array.

5295 (section_alignment): Declare only if not BFD_ASSEMBLER.
5296 (big_section, reg_section, pass1_section, diff_section,
5297 absent_section, text_section, data_section, bss_section): If
5298 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5299 mapping to segT enum values.
5300 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5301 if these are used or defined, if BFD_ASSEMBLER.
5302 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5303 subseg_new split into two functions.
5304 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5306 * as.h (volatile): Don't define if already defined.
5307 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5309 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5310 declare with format attribute for -Wformat checking.
5312 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5314 * app.c, config/tc-*.c: Don't include read.h, since it is already
5317 * These are based on patches from Minh Tran-le
5318 <mtranle@paris.intellicorp.com>.
5319 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5320 obj_format coffbfd and gas_target i386coff for target.
5321 (i[34]86-*-isc*): New host (uses sysv).
5322 * config/i386aix.mt: Removed (no longer used).
5323 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5325 (LDFLAGS): Added, defined as -shlib.
5326 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5327 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5328 (DOT_LABEL_PREFIX): Define.
5329 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5330 name rather than L0\001.
5331 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5333 * symbols.c, symbols.h (local_bss_counter): Removed.
5334 * write.c (write_object_file): bss no longer uses
5335 local_bss_counter. Pass correct data and bss size to
5336 VMS_write_object_file.

5340 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
5341 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
5342 (size_section): Restored sanity check.
5343 (do_relocs_for): Base section address on s_paddr rather than
5344 computing it. Adjust a29k R_IHIHALF special case to account for
5345 section paddr (used to require paddr to be zero). If there are no
5346 reclos, set s_relptr to 0. Set relocation size in object_headers.
5347 (fill_section): Always set s_vaddr here, removing
5348 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5349 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5350 Set STYP_INFO for .comment.
5351 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5352 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5354 H_{SET,GET}_* macros.
5355 (do_linenos_for): Set lineno size in object_headers.
5356 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5357 set s_vaddr here. If string_byte_count remains 4, set it back to
5358 0, and only write strings out if there are some. Call
5359 fill_section before do_relocs_for and do_linenos_for.
5360 (obj_coff_section): Handle optional quoted second argument giving
5361 section characteristics.
5362 (obj_coff_bss): Added to handle .bss.
5363 (obj_coff_ident): Added to handle .ident (puts string in .comment
5365 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5366 (fixup_mdeps): Change to segment. Call frag_wane after
5368 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5369 adjustment (already happened only for common symbols, but this is
5371 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
5372 * config/tc-i386.c (s_bss): Don't use if I386COFF.

5383 (do_scrub_next_char): For \", return " not '.
5384 (symbol_chars): Now const.
5386 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5387 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5389 * config/obj-coff.h: Don't use #elif.
5391 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5392 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5394 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5416 SEG_BSS, fill with NOP_OPCODE.
5417 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5418 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5419 using ZERO_BASED_SEGMENTS.
5420 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5421 never set segment address for SEG_E2 (.bss) and don't write out
5422 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5423 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5424 definitions, and don't merge tags with non-tags. Check for .bf
5425 rather than just checking whether the second character is b and
5426 the third character is f.
5427 (obj_coff_val): gcc can generate values which we don't handle
5428 correctly; discard information for now, since it only affects the
5429 debugging information.
5430 (tag_find_or_name): Don't insert tags in the symbol table.
5431 (yank_symbols): Don't merge labels.
5432 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5614 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5615 constant will not fit in an immediate field.
5616 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5674 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
5675 support for C source listings. (obj_coff_endef): look in the right
5676 part of the symbol for the symbol name
5678 * tc-m68k.c (get_num): make it work for all segments, not just the
5681 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

5692 * tc-z8k.c: lots of bug fixes
5694 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5696 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5697 #elif, since it is not supported by old compilers.
5698 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5699 couple of expressions in tc-m68k.c.
5701 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5703 * read.c (cons): If NO_RELOC is defined, use it.
5705 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5707 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5709 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5710 local labels to start with a .) and set REGISTER_PREFIX to %.
5711 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5729 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5730 sections starting from zero, rather than making them consecutive.
5731 This makes subsequent reloc calculations easier, esp if the object
5732 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5733 allocate lcomm in .data rather than in .bss. It seems that some
5734 tools can't cope with a non-zero sized bss before linkage.
5736 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5738 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5760 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5762 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5763 .word is < -32768 or > 32767. The -J flag causes the error to be
5764 ignored. This is to catch over-sized switches generated by gcc on
5765 systems which don't support the broken .word hack.
5766 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5767 write.c (fixup_segment): check for signed .word overflow if
5768 WARN_SIGNED_OVERFLOW_WORD.
5770 * write.c (fixup_segment): fixed missing parens in expression
5771 checking for byte or word overflow.

5787 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5789 * input-scrub.c (input_scrub_push): call input_file_begin, not
5791 messages.c (as_perror): print ": " between the passed in error and
5792 the strerror, like perror does.

5797 From Steve Chamberlain:
5798 Makefile.in: Handle m68*-*-coff*.
5799 read.c, read.h: add mult argument to s_space
5801 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5802 Motorola and MIT syntax; gas can now assemble either type of
5804 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5810 (write_object_file) call fixup_mdeps
5811 (fixup_segment) set fx_subsy to 0.
5812 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5814 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5817 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5819 * Makefile.in (LIBS): Include opcode library.

5844 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5846 * config/tc-m68k.c (init_table): Now const. Always include 68851
5847 data, so that "bc" is available to 68040 cache instructions.
5848 Added "tt0", "tt1", and 68ec030 variants.
5849 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5850 (enum _register): Added TT0, TT1.
5851 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5852 line number correctly in "internal error" messages. Don't print
5853 architecture-mismatch message for operand errors.
5855 From Colin Smith (colin@wrs.com):
5856 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

5878 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5879 has already been formatted (but may still contain %-characters).
5882 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5884 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5885 written with indirection on the last two operands, which can be
5886 either data or address registers. Added a new operand type 'r'
5887 which accepts either register type. Added '(' to notend stuff in
5888 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5907 their not having symbols associated.
5909 * tc-i960.c (norelax, instrument_branches): Default initializer is

6152 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
6154 * symbols.c (fb_label_init): fix sizeof to memset.
6156 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
6158 * Makefile.in: install the man page.
6160 * Makefile.in: pass down MAKEINFO explicitly on info.
6162 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
6164 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6166 * flonum-const.c: renamed flonum-konst.c to stop dos name
6169 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6171 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6172 tc-m68k.h to te-sun3.h.
6174 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6176 * configure.in: vxworks68 gets te-sun3.h.
6178 * expr.c: remove limitation that local_labels_dollar or
6179 local_labels_fb must be < 10.
6181 * symbols.c: remove local_labels_dollar, replace with a function
6182 interface for a sparse array. All users adjusted.
6184 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6186 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6188 * doc/Makefile.in: commented out line for building as-all.texinfo.
6191 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6193 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6195 * Makefile.in: added check target.
6197 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6199 * Makefile.in: added tooldir and program_prefix.
6201 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6203 * write.{c,h} (fix_new): Make these declarations consistent.
6205 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6207 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6210 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6212 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6214 * expr.c (operand): if can't work out what sort of operand it is,
6215 then look through FLT_CHARS for a hint.
6217 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6219 * Makefile.in, configure.in: removed traces of namesubdir,
6220 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6221 copyrights to '92, changed some from Cygnus to FSF.
6223 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6224 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6225 copyrights to '92, changed some from Cygnus to FSF.
6227 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6229 * expr.c: If an expression is single comma, then return with
6230 SEG_ABSENT rather than an error - since the sparc front end does
6231 really strange things with things like fbge,a
6233 * as.h: include bfd.h if using many sections
6234 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6235 local labels didn't work.
6236 * listing.c (list_symbol_table): don't core dump when there's no
6238 * write.c, write.h: call fix_new with the right number of args on
6240 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6243 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6245 * app.c: MRI compatibility - allow single quote to start a string.
6246 * as.c: fix typo recently introduced.
6247 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6248 * expr.c: Much rewriting, to accomodate MRI syntax for
6249 expressions. Also easier to read now.
6250 * listing.c: Put back defuns
6251 * read.c: modified to accept MRI syntax, put back listing pseudo
6252 ops so that an assembler built with NO_LISTING ignores list ops
6254 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6255 machine is a SPARC or a 29K.
6256 * config/obj-aout.c: added s_sect pseudo op
6257 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6258 fill in the timestamp.
6259 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6260 anymore, define all the relocs which the tc-<x> bit will use so we
6261 can translate from them to the coff types.
6262 * config/tc-a29k.c: reloc_type isn't ane enum any more
6263 * config/tc-m68k.c: Added NO_RELOC definition.
6265 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6267 * Makefile.in: put header files before C source for TAGS; remove
6268 references to non-existent syscalls.h.
6270 * read.c, write.c subsegs.c: back out the .bss changes.
6272 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6274 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6278 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6280 * symbols.c (local_label_name): symbols now start with ^A.
6282 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6283 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6284 generate these sections. .align: will use NOP_OPCODE or 0
6285 for padding. This is just for being nice to the
6288 * expr.c (operand): changed to generate local label "\001L0"
6289 starting with a ^A so that it is recognized as a local label.
6291 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6293 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6294 i/o opcodes - inb, inw, outb and outw. string manipulation with
6295 att syntax - scmp, slod, smov, ssca, ssto.
6297 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6298 to just after .file .
6300 In obj_crawl_symbol_chain() where it tries to put the external
6301 symbols apart, with the condition:
6302 (!S_IS_DEFINED(symbolP) &&
6303 !S_IS_DEBUG(symbolP) &&
6304 !SF_GET_STATICS(symbolP))
6305 it was moving too many symbols out. So I switch it back to the
6307 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6309 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6310 so that we don't use the F_RELFLG which make the linker complain
6311 that somebody has stripped the relocation info.
6313 Also, the AIX ld program require that the relocation table
6314 is sorted by r_vaddr like the standard ATT assembler does.
6316 [he also changed the sizeof(struct ...)'s into the coff
6317 style FOOSZ macros. I'm not sure this is right, but I can't
6318 remember why. xoxorich.]
6320 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6322 * Makefile.in, configure.in, doc: use the doc. Build it, install
6325 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6327 * read.c: white space and comments only.
6329 * configure.in: use the new atof-ns32.c for ns32k.
6331 * write.c: comment change only.
6333 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6334 aren't yet integrated.
6336 * tc-i860.[hc]: blew off the dust. Something must still be done
6337 about conflicting relocation types.
6339 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6342 * tc-i960.c, tc-sparc.c: white space and comments only.
6344 * tc-a29k.h: delete duplicate macro definition.
6346 * new file atof-ns32k.c copied from hack's last unreleased gas.
6348 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6350 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6353 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6354 ChangeLog's prior to this are sketchy at best. I have logs.
6355 They just aren't ChangeLogs.
6359 version-control: never
