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

74 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
75 flag rather than signedp field. Only permit extended range if
76 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
77 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
79 * config/tc-ppc.c (ppc_size): New static variable.
80 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
81 (md_begin): If an instruction has a size specific flag set, only
82 add it if we are assembling that size.

102 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
103 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),

115 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
117 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
118 branch with an instruction that uses $at, in case the branch is
120 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
121 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
122 to make it pcrel_offset.
123 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
124 reloc->address; another gruesome hack to get gas reloc handling to
127 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

136 (lituse_pending): New variable. Set by anything that generates a
137 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
138 tested by code that might want to emit a LITUSE reloc.
139 (emit_unaligned_io): New function. Currently calls md_assemble,
140 but it should eventually be converted to generate the insn itself
141 and call emit_insn directly.
142 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
143 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
144 emit_bis_r): Likewise.

155 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
156 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

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

193 * Makefile.in (config-stamp): If `defs' is defined, emit a
194 preprocessor directive to create a macro named by this value into
195 config.new; don't explicitly go for BFD_ASSEMBLER.
196 * configure.in: Define `defs', not `BFDDEF'. Set it to
197 MANY_SEGMENTS for any obj-coffbfd target.
198 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
199 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

229 bfd_set_symtab is called.
230 (dump_section_relocs): Note whether a symbol is a section symbol
232 (adjust_reloc_syms): For now, always supply an absolute symbol for
233 fixups without symbols but not yet `done'. Use section_symbol to
234 get the symbol, instead of going directly for abs_symbol.
235 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
236 reloc is not a section symbol and is not in the symbol table.
237 (set_symtab): New function, broken out from write_object_file.
238 Counts symbol table instead of relying on an earlier count.
239 (write_object_file): Call set_symtab, but do it after potentially
240 invoking the *_frob_file macros. Don't bother counting symbols.
241 Call symbol_remove, instead of expanding it in place. Moved the
242 conditionalized `object_file_size' declaration down to
243 conditionalized block where it's used. When using the absolute
244 symbol for a fixup without a symbol, set sy_used_in_reloc.
245 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
246 the correct symbol for the absolute section.
248 * subsegs.c (section_symbol): Use symbol_new instead of
249 symbol_make, since we may want it to go into the symbol table.
250 Make the new symbol have internal linkage. If
251 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
252 symbol with the newly created GAS symbol.
253 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
254 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

259 (in_signed_range): New function.
261 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
262 (sparc_ip, label "immediate"): Reject constants for pcrel
263 instructions only if the relocation type indicates a "call"
264 instruction and the offset is within range of a "jmpl %g0". If
265 it's not in range, use the absolute section symbol plus an offset.
266 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
268 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
270 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
273 * configure.in: Eliminated all targets using obj-coff but not
274 defining BFD_ASSEMBLER; I think all such targets that are
275 supported will be matched by real CPU-OS combinations earlier in
277 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
278 some comments about the dpx2 configuration, but left it disabled,
279 since it couldn't be reached before.
280 (target a29k-amd-ebmonold): Deleted.
282 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

290 the 'j' operand if there are no further alternatives for this
293 * config/obj-coffbfd.c (adjust_stab_section): Initialize
294 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
295 is not SEG_UNKNOWN rather than checking whether it is >= 0.
297 * config/tc-mips.c (mips_align): Take new argument, label, and use
298 it instead of global insn_label.
299 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
300 call to mips_emit_delay and pass it to mips_align.
302 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
304 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
306 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
307 argument to a .callinfo directive. Don't loop forever on errors.
309 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
310 use pre-defined registers as arguments.
312 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
314 * write.c (write_object_file): Check both S_IS_LOCAL and
315 S_IS_EXTERNAL when deciding whether to discard a symbol.
317 * config-gas.com: Scan Makefile.in, not version.c, for current
318 version number. Delete all versions of temp files when finished
319 with them. Create config.h.
321 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
322 values to reduce number of lookups with S_GET_VALUE. Skip debug
323 symbols to avoid "a really nasty bug". (From Holger Teutsch,
324 holger@botbso.rhein-main.de.)
325 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
326 field. (Also from Holger Teutsch.) Watch for a would-be register
327 mask that spans frags.
329 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
330 this_base, not line_base. (Patch from Andreas Arens,
331 ari@obelix.av.rwth-aachen.de.)
333 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
334 look local if they're exported or undefined. Used to be done for
337 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
338 Get it from the looked-up symbol, instead of using the string from
339 the input stream, which is no longer null-terminated.

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

350 * Makefile.in (literal.o): Provide dependencies.
352 * configure.in: Set new makefile variable OPCODES_LIB.

405 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
406 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2460 default is to assume production environment, and reject configs
2461 still being worked on. Mark Elf configurations (except sparc and
2462 i386) as developmental. Deleted cases matching some generic names
2463 in favor of more specific names. (E.g., when we get Alpha

2481 for functions only used within tc-hppa.c, likewise for structures,
2482 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2483 conditional code in a few small places.
2485 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2486 structures, global variables, forward declarations together.

2488 conditional code -- try to group conditional code together
2489 into a few places. Make all functions and variables which
2490 are only used within tc-hppa.c static. PARAMize all functions.
2491 Add comments to functions. Delete unused functions, variables,
2492 #defines, etc. Delete unused members within structures. Delete
2493 ldil;ble hacks -- it is believed they were installed to work
2494 around old gas bugs. Avoid using mixed case for local
2495 functions, variables, and structures. Fix formatting problems
2496 not found by GNU-indent. Add FIXME notices for things which
2497 should be worked on the near future. Delete lots of old
2498 useless (1.36 PA-SOM) code.

2515 * config/tc-hppa.c: Likewise.
2517 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2518 of elf32_symbol_type.
2519 (pa_export_args): Likewise.
2520 (elf_hppa_final_processing): Likewise.

2527 a multiple of the section alignment rather than always a
2530 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2571 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2573 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2574 ELF, since the ELF object format does not have these type of
2575 relocations. Change the abort into as as_bad and return
2576 BFD_RELOC_NONE to silence compiler warnings.
2577 (md_assemble): Keep track of the instruction size. Allow white
2578 space between the $ and the constant for compatibility with older
2579 gases and other assemblers.

4968 avoid some redefinition complaints on some systems.
4969 (const, volatile): Don't need these conditionally defined if we
4970 use CONST and VOLATILE from ansidecl.h.
4971 (seg_name): Use CONST, not const.

4979 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4980 (fixup_segment): Add a29k special case; the linker is not prepared
4981 to see a segment offset here.
4983 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4986 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4988 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4989 srcdir, might be in objdir.

5008 * Makefile.in (targ-cpu.o): Depend on config.h.
5010 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5012 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5013 dropping a space immediately following an identifier.

5015 lines; I don't think that can be done portably.
5016 * config/tc-mips.c (macro): Use $AT if target register is zero in
5017 load instruction, which it can be for a floating point load.
5019 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5040 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5042 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5043 to be on a single line.

5091 prototypes for all static functions. Moved existing minimal
5092 debugging format support info #ifndef OBJ_ECOFF blocks.

5141 * make-gas.com: Find obstack.obj if it's not in the current
5143 * read.c (s_ignore): Don't declare is_end_of_line. It's
5144 redundant, and triggers a VMS gcc compiler bug.
5146 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5147 current segment as an argument. (Ignored in all cases but VMS.)
5148 All callers and definitions changed.

5445 md_relax_table): Use default zero initialization.
5446 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5447 latter, instead of selecting with preprocessor conditionals.
5449 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5451 * configure.in: recognise all sparclite variants

5461 * expr.c (operand): If character other than comma or newline is a
5462 logical end-of-line character, use the newline case.
5463 From Eric Youngdale:
5464 (operand): Set X_add_number field for floating-point numbers.
5465 (operand): Treat zero byte as end-of-operand.
5467 * configure.in (per-target): Look for with_bfd_assembler option.
5468 For now, only accept "no", until the merge is done.
5470 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5471 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5477 * expr.c: Add "const" modifier to hex_value.
5478 * symbols.c: Finish conversion to S_* macros in the VMS only
5479 parts of the program. Add "const" modifier to
5480 md_[long,short]_jump_size. Remove declaration of const_flag
5481 (which will be declared in obj-vms.h).
5482 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5483 Fix arguments to VMS_write_object_file.
5484 * config-gas.com: New file. Script for VMS systems to set up the
5485 configuration to build gas for VMS, and create config.status.
5486 * make-gas.com: Redone to work with new scheme.
5487 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

5492 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5493 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5494 types of malformed stabs. Change parsing algorithm so that we are
5495 more certain of having all of the information that we need on hand.
5496 * obj-vms.c (final_forward_reference): New function, used to help
5497 resolve the data types of as many struct elements as possible
5498 when some part of the struct is not fully defined by the compiler.

5501 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5502 as symbols as well in the object file. Look for external functions
5503 that start with "__vt.", and turn them into variables, since the
5504 g++ compiler is incapable of doing this.
5505 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5507 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

5515 SEG_DATA or SEG_E1 if needed.
5516 (s_lcomm): Likewise with bss_section.
5517 (s_fill): Use memset, not bzero.
5519 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5542 absent_section, text_section, data_section, bss_section): If
5543 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5544 mapping to segT enum values.
5545 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5546 if these are used or defined, if BFD_ASSEMBLER.
5547 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5548 subseg_new split into two functions.
5549 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5551 * as.h (volatile): Don't define if already defined.
5552 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5554 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5555 declare with format attribute for -Wformat checking.
5557 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5559 * app.c, config/tc-*.c: Don't include read.h, since it is already
5562 * These are based on patches from Minh Tran-le
5563 <mtranle@paris.intellicorp.com>.
5564 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5565 obj_format coffbfd and gas_target i386coff for target.

5567 * config/i386aix.mt: Removed (no longer used).
5568 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5570 (LDFLAGS): Added, defined as -shlib.
5571 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5572 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5573 (DOT_LABEL_PREFIX): Define.
5574 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5575 name rather than L0\001.
5576 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5578 * symbols.c, symbols.h (local_bss_counter): Removed.
5579 * write.c (write_object_file): bss no longer uses
5580 local_bss_counter. Pass correct data and bss size to
5581 VMS_write_object_file.

5587 (size_section): Restored sanity check.
5588 (do_relocs_for): Base section address on s_paddr rather than
5589 computing it. Adjust a29k R_IHIHALF special case to account for
5590 section paddr (used to require paddr to be zero). If there are no
5591 reclos, set s_relptr to 0. Set relocation size in object_headers.
5592 (fill_section): Always set s_vaddr here, removing
5593 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5594 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5595 Set STYP_INFO for .comment.
5596 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5597 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5599 H_{SET,GET}_* macros.
5600 (do_linenos_for): Set lineno size in object_headers.
5601 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5602 set s_vaddr here. If string_byte_count remains 4, set it back to
5603 0, and only write strings out if there are some. Call
5604 fill_section before do_relocs_for and do_linenos_for.
5605 (obj_coff_section): Handle optional quoted second argument giving
5606 section characteristics.
5607 (obj_coff_bss): Added to handle .bss.
5608 (obj_coff_ident): Added to handle .ident (puts string in .comment
5610 (obj_coff_lcomm): Put common symbols in .bss, not .data.
5611 (fixup_mdeps): Change to segment. Call frag_wane after

5634 * config/obj-coff.h: Don't use #elif.
5636 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

5823 could be doing emulation.
5825 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5828 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5898 * Support for i386-sysv.
5899 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5937 * tc-z8k.c: lots of bug fixes
5939 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5941 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5942 #elif, since it is not supported by old compilers.
5943 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5944 couple of expressions in tc-m68k.c.
5946 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

5972 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5974 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5975 sections starting from zero, rather than making them consecutive.
5976 This makes subsequent reloc calculations easier, esp if the object
5977 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5978 allocate lcomm in .data rather than in .bss. It seems that some
5979 tools can't cope with a non-zero sized bss before linkage.

6002 * Makefile.in (install): if $(tooldir) exists, install as in
6005 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6007 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6008 .word is < -32768 or > 32767. The -J flag causes the error to be
6009 ignored. This is to catch over-sized switches generated by gcc on
6010 systems which don't support the broken .word hack.
6011 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6012 write.c (fixup_segment): check for signed .word overflow if
6013 WARN_SIGNED_OVERFLOW_WORD.
6015 * write.c (fixup_segment): fixed missing parens in expression
6016 checking for byte or word overflow.

6032 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6034 * input-scrub.c (input_scrub_push): call input_file_begin, not
6036 messages.c (as_perror): print ": " between the passed in error and
6037 the strerror, like perror does.
6039 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

6057 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6059 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6062 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6064 * Makefile.in (LIBS): Include opcode library.

6089 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6091 * config/tc-m68k.c (init_table): Now const. Always include 68851
6092 data, so that "bc" is available to 68040 cache instructions.
6093 Added "tt0", "tt1", and 68ec030 variants.
6094 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6095 (enum _register): Added TT0, TT1.
6096 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6097 line number correctly in "internal error" messages. Don't print
6098 architecture-mismatch message for operand errors.
6100 From Colin Smith (colin@wrs.com):
6101 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6102 than install_operand.

6127 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6129 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6130 written with indirection on the last two operands, which can be
6131 either data or address registers. Added a new operand type 'r'
6132 which accepts either register type. Added '(' to notend stuff in
6133 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6245 characteristics have been), default to 68020. Don't need extra
6246 quotes around error string.

6328 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6330 * write.c (write_object_file): keep the fix_tail clean, which
6331 fixes a bug in -R where relocations were being lost.
6333 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6335 * configure.in: recognize m680x0 as having sun3 emulation mode for

6379 * write.c (write_object_file): For b.out format, round up section
6380 start addresses to match required alignment.
6382 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6384 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6385 where gcc looks for it.
6387 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6389 * Makefile.in: Changed some lines to be less confusing for some

6455 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6457 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6459 * expr.c (operand): if can't work out what sort of operand it is,
6460 then look through FLT_CHARS for a hint.
6462 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6464 * Makefile.in, configure.in: removed traces of namesubdir,

6466 copyrights to '92, changed some from Cygnus to FSF.
6468 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6469 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6470 copyrights to '92, changed some from Cygnus to FSF.
6472 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6474 * expr.c: If an expression is single comma, then return with
6475 SEG_ABSENT rather than an error - since the sparc front end does
6476 really strange things with things like fbge,a
6478 * as.h: include bfd.h if using many sections
6479 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6480 local labels didn't work.
6481 * listing.c (list_symbol_table): don't core dump when there's no
6483 * write.c, write.h: call fix_new with the right number of args on
6485 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6488 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6490 * app.c: MRI compatibility - allow single quote to start a string.
6491 * as.c: fix typo recently introduced.
6492 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6493 * expr.c: Much rewriting, to accomodate MRI syntax for
6494 expressions. Also easier to read now.
6495 * listing.c: Put back defuns
6496 * read.c: modified to accept MRI syntax, put back listing pseudo
6497 ops so that an assembler built with NO_LISTING ignores list ops
6499 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6500 machine is a SPARC or a 29K.
6501 * config/obj-aout.c: added s_sect pseudo op
6502 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6503 fill in the timestamp.
6504 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6505 anymore, define all the relocs which the tc-<x> bit will use so we
6506 can translate from them to the coff types.
6507 * config/tc-a29k.c: reloc_type isn't ane enum any more
6508 * config/tc-m68k.c: Added NO_RELOC definition.
6510 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6512 * Makefile.in: put header files before C source for TAGS; remove
6513 references to non-existent syscalls.h.
6515 * read.c, write.c subsegs.c: back out the .bss changes.
6517 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6519 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6523 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6525 * symbols.c (local_label_name): symbols now start with ^A.
6527 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6528 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6529 generate these sections. .align: will use NOP_OPCODE or 0
6530 for padding. This is just for being nice to the
6533 * expr.c (operand): changed to generate local label "\001L0"
6534 starting with a ^A so that it is recognized as a local label.
6536 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6538 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6539 i/o opcodes - inb, inw, outb and outw. string manipulation with
6540 att syntax - scmp, slod, smov, ssca, ssto.
6542 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6543 to just after .file .
6545 In obj_crawl_symbol_chain() where it tries to put the external
6546 symbols apart, with the condition:
6547 (!S_IS_DEFINED(symbolP) &&
6548 !S_IS_DEBUG(symbolP) &&
6549 !SF_GET_STATICS(symbolP))
6550 it was moving too many symbols out. So I switch it back to the
6552 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6554 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6555 so that we don't use the F_RELFLG which make the linker complain
6556 that somebody has stripped the relocation info.
6558 Also, the AIX ld program require that the relocation table
6559 is sorted by r_vaddr like the standard ATT assembler does.
6561 [he also changed the sizeof(struct ...)'s into the coff
6562 style FOOSZ macros. I'm not sure this is right, but I can't
6563 remember why. xoxorich.]
6565 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

6572 * read.c: white space and comments only.
6574 * configure.in: use the new atof-ns32.c for ns32k.
6576 * write.c: comment change only.
6578 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6579 aren't yet integrated.
6581 * tc-i860.[hc]: blew off the dust. Something must still be done
6582 about conflicting relocation types.
6584 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6587 * tc-i960.c, tc-sparc.c: white space and comments only.
6589 * tc-a29k.h: delete duplicate macro definition.
6591 * new file atof-ns32k.c copied from hack's last unreleased gas.
6593 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6595 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6598 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6599 ChangeLog's prior to this are sketchy at best. I have logs.
6600 They just aren't ChangeLogs.
6604 version-control: never
