63 elf_tc_make_sections stuff. It was there to support PA braindamage
64 which has been fixed, and in the case of elf_tc_make_sections is
65 redundant with elf_tc_final_processing.

99 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
100 flag rather than signedp field. Only permit extended range if
101 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
102 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
104 * config/tc-ppc.c (ppc_size): New static variable.
105 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.

127 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
128 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
129 and -many (all architectures).

139 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
140 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
142 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
143 branch with an instruction that uses $at, in case the branch is
145 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
146 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
147 to make it pcrel_offset.
148 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
149 reloc->address; another gruesome hack to get gas reloc handling to
152 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
154 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

161 (lituse_pending): New variable. Set by anything that generates a
162 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
163 tested by code that might want to emit a LITUSE reloc.
164 (emit_unaligned_io): New function. Currently calls md_assemble,
165 but it should eventually be converted to generate the insn itself
166 and call emit_insn directly.
167 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
168 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
169 emit_bis_r): Likewise.

176 the value can't be resolved.
178 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
180 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
181 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

197 (load_address): Handle EMBEDDED_PIC.
198 (macro): Handle EMBEDDED_PIC in all PIC cases.
199 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
200 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
201 -non_shared to use NO_PIC (this is how the Irix 5 assembler
202 works). Do not permit -G with SVR4_PIC.
203 (s_abicalls): Warn if -G was used, and force -G 0.
204 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
205 anything but a.out, not just for ELF. For ECOFF, don't generate a
206 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
208 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
210 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

216 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
218 * Makefile.in (config-stamp): If `defs' is defined, emit a
219 preprocessor directive to create a macro named by this value into
220 config.new; don't explicitly go for BFD_ASSEMBLER.
221 * configure.in: Define `defs', not `BFDDEF'. Set it to
222 MANY_SEGMENTS for any obj-coffbfd target.
223 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
224 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
226 (LOCAL_LOADLIBES): Deleted.
227 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
228 * config/m88kcoff.mt (TDEFINES): Ditto.

254 bfd_set_symtab is called.
255 (dump_section_relocs): Note whether a symbol is a section symbol
257 (adjust_reloc_syms): For now, always supply an absolute symbol for
258 fixups without symbols but not yet `done'. Use section_symbol to
259 get the symbol, instead of going directly for abs_symbol.
260 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
261 reloc is not a section symbol and is not in the symbol table.
262 (set_symtab): New function, broken out from write_object_file.
263 Counts symbol table instead of relying on an earlier count.
264 (write_object_file): Call set_symtab, but do it after potentially
265 invoking the *_frob_file macros. Don't bother counting symbols.
266 Call symbol_remove, instead of expanding it in place. Moved the
267 conditionalized `object_file_size' declaration down to
268 conditionalized block where it's used. When using the absolute
269 symbol for a fixup without a symbol, set sy_used_in_reloc.
270 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
271 the correct symbol for the absolute section.
273 * subsegs.c (section_symbol): Use symbol_new instead of
274 symbol_make, since we may want it to go into the symbol table.
275 Make the new symbol have internal linkage. If
276 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
277 symbol with the newly created GAS symbol.
278 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
279 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

284 (in_signed_range): New function.
286 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
287 (sparc_ip, label "immediate"): Reject constants for pcrel
288 instructions only if the relocation type indicates a "call"
289 instruction and the offset is within range of a "jmpl %g0". If
290 it's not in range, use the absolute section symbol plus an offset.
291 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
293 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
295 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
298 * configure.in: Eliminated all targets using obj-coff but not
299 defining BFD_ASSEMBLER; I think all such targets that are
300 supported will be matched by real CPU-OS combinations earlier in
302 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
303 some comments about the dpx2 configuration, but left it disabled,
304 since it couldn't be reached before.
305 (target a29k-amd-ebmonold): Deleted.
307 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
309 * config/tc-hppa.c (pa_import): Correctly handle importing of an
310 already defined symbol.

315 the 'j' operand if there are no further alternatives for this
318 * config/obj-coffbfd.c (adjust_stab_section): Initialize
319 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
320 is not SEG_UNKNOWN rather than checking whether it is >= 0.
322 * config/tc-mips.c (mips_align): Take new argument, label, and use
323 it instead of global insn_label.
324 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
325 call to mips_emit_delay and pass it to mips_align.
327 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
329 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
331 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
332 argument to a .callinfo directive. Don't loop forever on errors.
334 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
335 use pre-defined registers as arguments.
337 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
339 * write.c (write_object_file): Check both S_IS_LOCAL and
340 S_IS_EXTERNAL when deciding whether to discard a symbol.
342 * config-gas.com: Scan Makefile.in, not version.c, for current
343 version number. Delete all versions of temp files when finished
344 with them. Create config.h.
346 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
347 values to reduce number of lookups with S_GET_VALUE. Skip debug

349 holger@botbso.rhein-main.de.)
350 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
351 field. (Also from Holger Teutsch.) Watch for a would-be register
352 mask that spans frags.
354 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
355 this_base, not line_base. (Patch from Andreas Arens,
356 ari@obelix.av.rwth-aachen.de.)
358 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
359 look local if they're exported or undefined. Used to be done for
362 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
363 Get it from the looked-up symbol, instead of using the string from
364 the input stream, which is no longer null-terminated.

366 (lex_type): Use it for `%'.
368 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
369 (vip_op): Now static, and returns void. Callers changed. Added

429 (obj_coff_section): Declare.
430 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
431 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

433 silently compiling to do nothing.
434 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define only if
436 (OBJ_PROCESS_STAB) [! MANY_SECTIONS]: New macro, just emits

2371 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2372 the table, require that the one without bit 0x1000000 set come
2373 first. Require further that it be case 'b' or 'P'. The a29k
2374 opcode table already meets these constraints.
2375 (machine_ip): When handling case 'i' or 'A', make sure that the

2427 * write.c (write_relocs): For relocs that are pc_relative and
2428 pcrel_offset and not partial_inplace, adjust reloc->addend to

2483 * configure.in: Set bfd_gas for all sparc targets. Added facility
2484 for keeping or rejecting configurations still under development;
2485 default is to assume production environment, and reject configs
2486 still being worked on. Mark Elf configurations (except sparc and
2487 i386) as developmental. Deleted cases matching some generic names
2488 in favor of more specific names. (E.g., when we get Alpha

2505 through inclusion of tc-hppa.h. Delete all forward declarations
2506 for functions only used within tc-hppa.c, likewise for structures,
2507 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2508 conditional code in a few small places.
2510 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2511 structures, global variables, forward declarations together.

2513 conditional code -- try to group conditional code together
2514 into a few places. Make all functions and variables which
2515 are only used within tc-hppa.c static. PARAMize all functions.
2516 Add comments to functions. Delete unused functions, variables,
2517 #defines, etc. Delete unused members within structures. Delete
2518 ldil;ble hacks -- it is believed they were installed to work
2519 around old gas bugs. Avoid using mixed case for local
2520 functions, variables, and structures. Fix formatting problems
2521 not found by GNU-indent. Add FIXME notices for things which
2522 should be worked on the near future. Delete lots of old
2523 useless (1.36 PA-SOM) code.

2540 * config/tc-hppa.c: Likewise.
2542 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2543 of elf32_symbol_type.
2544 (pa_export_args): Likewise.
2545 (elf_hppa_final_processing): Likewise.
2546 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

2551 * config/tc-hppa.c: (md_section_align): Align all sections to
2552 a multiple of the section alignment rather than always a
2555 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2596 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2598 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2599 ELF, since the ELF object format does not have these type of
2600 relocations. Change the abort into as as_bad and return
2601 BFD_RELOC_NONE to silence compiler warnings.
2602 (md_assemble): Keep track of the instruction size. Allow white
2603 space between the $ and the constant for compatibility with older
2604 gases and other assemblers.
2605 (i386_operand): Skip spaces between $ and expression.
2606 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

4993 avoid some redefinition complaints on some systems.

5166 * make-gas.com: Find obstack.obj if it's not in the current
5168 * read.c (s_ignore): Don't declare is_end_of_line. It's
5169 redundant, and triggers a VMS gcc compiler bug.
5171 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5172 current segment as an argument. (Ignored in all cases but VMS.)
5173 All callers and definitions changed.

5490 (operand): Treat zero byte as end-of-operand.
5492 * configure.in (per-target): Look for with_bfd_assembler option.
5493 For now, only accept "no", until the merge is done.
5495 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5496 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5502 * expr.c: Add "const" modifier to hex_value.
5503 * symbols.c: Finish conversion to S_* macros in the VMS only
5504 parts of the program. Add "const" modifier to
5505 md_[long,short]_jump_size. Remove declaration of const_flag
5506 (which will be declared in obj-vms.h).
5507 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5508 Fix arguments to VMS_write_object_file.
5509 * config-gas.com: New file. Script for VMS systems to set up the
5510 configuration to build gas for VMS, and create config.status.

5526 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5527 as symbols as well in the object file. Look for external functions

5540 SEG_DATA or SEG_E1 if needed.
5541 (s_lcomm): Likewise with bss_section.
5542 (s_fill): Use memset, not bzero.
5544 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5569 mapping to segT enum values.
5570 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5571 if these are used or defined, if BFD_ASSEMBLER.
5572 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5573 subseg_new split into two functions.
5574 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5576 * as.h (volatile): Don't define if already defined.
5577 (had_errors, had_warnings): Provide prototypes for ANSI C even if

5613 (do_relocs_for): Base section address on s_paddr rather than
5614 computing it. Adjust a29k R_IHIHALF special case to account for
5615 section paddr (used to require paddr to be zero). If there are no
5616 reclos, set s_relptr to 0. Set relocation size in object_headers.
5617 (fill_section): Always set s_vaddr here, removing
5618 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5619 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5620 Set STYP_INFO for .comment.
5621 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5622 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
5623 (crawl_symbols): Handle 8 character section name correctly. Use
5624 H_{SET,GET}_* macros.
5625 (do_linenos_for): Set lineno size in object_headers.
5626 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5627 set s_vaddr here. If string_byte_count remains 4, set it back to
5628 0, and only write strings out if there are some. Call
5629 fill_section before do_relocs_for and do_linenos_for.
5630 (obj_coff_section): Handle optional quoted second argument giving
5631 section characteristics.
5632 (obj_coff_bss): Added to handle .bss.
5633 (obj_coff_ident): Added to handle .ident (puts string in .comment
5635 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5636 (fixup_mdeps): Change to segment. Call frag_wane after
5638 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5639 adjustment (already happened only for common symbols, but this is

5653 (do_scrub_next_char): For \", return " not '.
5654 (symbol_chars): Now const.
5656 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5657 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5659 * config/obj-coff.h: Don't use #elif.
5661 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5662 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5692 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5693 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5694 definitions, and don't merge tags with non-tags. Check for .bf
5695 rather than just checking whether the second character is b and
5696 the third character is f.
5697 (obj_coff_val): gcc can generate values which we don't handle
5698 correctly; discard information for now, since it only affects the
5699 debugging information.

5701 (yank_symbols): Don't merge labels.
5702 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5848 could be doing emulation.
5850 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5853 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5923 * Support for i386-sysv.
5924 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5962 * tc-z8k.c: lots of bug fixes
5964 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5966 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5967 #elif, since it is not supported by old compilers.
5968 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5969 couple of expressions in tc-m68k.c.
5971 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5973 * read.c (cons): If NO_RELOC is defined, use it.

5979 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5980 local labels to start with a .) and set REGISTER_PREFIX to %.
5981 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5983 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5997 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5999 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6000 sections starting from zero, rather than making them consecutive.
6001 This makes subsequent reloc calculations easier, esp if the object
6002 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6003 allocate lcomm in .data rather than in .bss. It seems that some
6004 tools can't cope with a non-zero sized bss before linkage.
6006 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6008 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6009 throughout. That enum no longer means what we thought it meant.

6012 "-mno-688[58]1" options.
6014 * tc-m68k.c: Added CPU32 support.

6027 * Makefile.in (install): if $(tooldir) exists, install as in
6030 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6032 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6033 .word is < -32768 or > 32767. The -J flag causes the error to be
6034 ignored. This is to catch over-sized switches generated by gcc on
6035 systems which don't support the broken .word hack.
6036 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6037 write.c (fixup_segment): check for signed .word overflow if
6038 WARN_SIGNED_OVERFLOW_WORD.
6040 * write.c (fixup_segment): fixed missing parens in expression
6041 checking for byte or word overflow.

6055 * tc-i386.h : new coff defines
6057 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6059 * input-scrub.c (input_scrub_push): call input_file_begin, not
6061 messages.c (as_perror): print ": " between the passed in error and
6062 the strerror, like perror does.
6064 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6066 * Makefile.in: use gas_target instead of modifying target_cpu.
6067 From Steve Chamberlain:
6068 Makefile.in: Handle m68*-*-coff*.
6069 read.c, read.h: add mult argument to s_space
6071 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6072 Motorola and MIT syntax; gas can now assemble either type of
6074 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6079 (fill_section) added rs_machine_dependent case
6080 (write_object_file) call fixup_mdeps
6081 (fixup_segment) set fx_subsy to 0.
6082 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6084 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6087 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6089 * Makefile.in (LIBS): Include opcode library.

6116 * config/tc-m68k.c (init_table): Now const. Always include 68851
6117 data, so that "bc" is available to 68040 cache instructions.
6118 Added "tt0", "tt1", and 68ec030 variants.
6119 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6120 (enum _register): Added TT0, TT1.

6152 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6154 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6155 written with indirection on the last two operands, which can be
6156 either data or address registers. Added a new operand type 'r'
6157 which accepts either register type. Added '(' to notend stuff in
6158 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6270 characteristics have been), default to 68020. Don't need extra
6271 quotes around error string.

6275 * read.c (potable): Revert sac's incorrect change made Jul 13.

6353 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6355 * write.c (write_object_file): keep the fix_tail clean, which
6356 fixes a bug in -R where relocations were being lost.
6358 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6360 * configure.in: recognize m680x0 as having sun3 emulation mode for

6404 * write.c (write_object_file): For b.out format, round up section
6405 start addresses to match required alignment.
6407 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6409 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6410 where gcc looks for it.
6412 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6414 * Makefile.in: Changed some lines to be less confusing for some

6487 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6489 * Makefile.in, configure.in: removed traces of namesubdir,

6493 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6494 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6495 copyrights to '92, changed some from Cygnus to FSF.
6497 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6499 * expr.c: If an expression is single comma, then return with
6500 SEG_ABSENT rather than an error - since the sparc front end does
6501 really strange things with things like fbge,a
6503 * as.h: include bfd.h if using many sections
6504 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6505 local labels didn't work.
6506 * listing.c (list_symbol_table): don't core dump when there's no
6508 * write.c, write.h: call fix_new with the right number of args on
6510 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6513 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6515 * app.c: MRI compatibility - allow single quote to start a string.
6516 * as.c: fix typo recently introduced.
6517 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6518 * expr.c: Much rewriting, to accomodate MRI syntax for
6519 expressions. Also easier to read now.
6520 * listing.c: Put back defuns
6521 * read.c: modified to accept MRI syntax, put back listing pseudo
6522 ops so that an assembler built with NO_LISTING ignores list ops
6524 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6525 machine is a SPARC or a 29K.
6526 * config/obj-aout.c: added s_sect pseudo op
6527 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6528 fill in the timestamp.
6529 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6530 anymore, define all the relocs which the tc-<x> bit will use so we
6531 can translate from them to the coff types.
6532 * config/tc-a29k.c: reloc_type isn't ane enum any more
6533 * config/tc-m68k.c: Added NO_RELOC definition.
6535 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6537 * Makefile.in: put header files before C source for TAGS; remove
6538 references to non-existent syscalls.h.
6540 * read.c, write.c subsegs.c: back out the .bss changes.
6542 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6544 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6548 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6550 * symbols.c (local_label_name): symbols now start with ^A.
6552 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6553 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6554 generate these sections. .align: will use NOP_OPCODE or 0
6555 for padding. This is just for being nice to the
6558 * expr.c (operand): changed to generate local label "\001L0"
6559 starting with a ^A so that it is recognized as a local label.
6561 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6563 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6564 i/o opcodes - inb, inw, outb and outw. string manipulation with
6565 att syntax - scmp, slod, smov, ssca, ssto.
6567 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6568 to just after .file .
6570 In obj_crawl_symbol_chain() where it tries to put the external
6571 symbols apart, with the condition:
6572 (!S_IS_DEFINED(symbolP) &&
6573 !S_IS_DEBUG(symbolP) &&
6574 !SF_GET_STATICS(symbolP))
6575 it was moving too many symbols out. So I switch it back to the
6577 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6579 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6580 so that we don't use the F_RELFLG which make the linker complain
6581 that somebody has stripped the relocation info.
6583 Also, the AIX ld program require that the relocation table
6584 is sorted by r_vaddr like the standard ATT assembler does.
6586 [he also changed the sizeof(struct ...)'s into the coff
6587 style FOOSZ macros. I'm not sure this is right, but I can't
6588 remember why. xoxorich.]
6590 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6592 * Makefile.in, configure.in, doc: use the doc. Build it, install

6597 * read.c: white space and comments only.
6599 * configure.in: use the new atof-ns32.c for ns32k.
6601 * write.c: comment change only.
6603 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6604 aren't yet integrated.
6606 * tc-i860.[hc]: blew off the dust. Something must still be done
6607 about conflicting relocation types.
6609 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
