9 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
10 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
12 * config/tc-ppc.c (ppc_size): New static variable.
13 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
14 (md_begin): If an instruction has a size specific flag set, only

48 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
50 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
51 branch with an instruction that uses $at, in case the branch is
53 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
54 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
55 to make it pcrel_offset.
56 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
57 reloc->address; another gruesome hack to get gas reloc handling to

62 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
65 (emit_insn): New function.
66 (md_assemble): Call it.
67 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
69 (lituse_pending): New variable. Set by anything that generates a
70 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
71 tested by code that might want to emit a LITUSE reloc.
72 (emit_unaligned_io): New function. Currently calls md_assemble,
73 but it should eventually be converted to generate the insn itself
74 and call emit_insn directly.
75 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
76 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
77 emit_bis_r): Likewise.

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

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

124 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
126 * Makefile.in (config-stamp): If `defs' is defined, emit a
127 preprocessor directive to create a macro named by this value into
128 config.new; don't explicitly go for BFD_ASSEMBLER.
129 * configure.in: Define `defs', not `BFDDEF'. Set it to
130 MANY_SEGMENTS for any obj-coffbfd target.
131 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
132 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
134 (LOCAL_LOADLIBES): Deleted.
135 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
136 * config/m88kcoff.mt (TDEFINES): Ditto.

162 bfd_set_symtab is called.
163 (dump_section_relocs): Note whether a symbol is a section symbol
165 (adjust_reloc_syms): For now, always supply an absolute symbol for
166 fixups without symbols but not yet `done'. Use section_symbol to
167 get the symbol, instead of going directly for abs_symbol.
168 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
169 reloc is not a section symbol and is not in the symbol table.
170 (set_symtab): New function, broken out from write_object_file.
171 Counts symbol table instead of relying on an earlier count.
172 (write_object_file): Call set_symtab, but do it after potentially
173 invoking the *_frob_file macros. Don't bother counting symbols.
174 Call symbol_remove, instead of expanding it in place. Moved the
175 conditionalized `object_file_size' declaration down to
176 conditionalized block where it's used. When using the absolute
177 symbol for a fixup without a symbol, set sy_used_in_reloc.
178 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
179 the correct symbol for the absolute section.
181 * subsegs.c (section_symbol): Use symbol_new instead of
182 symbol_make, since we may want it to go into the symbol table.
183 Make the new symbol have internal linkage. If
184 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
185 symbol with the newly created GAS symbol.
186 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
187 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

194 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
195 (sparc_ip, label "immediate"): Reject constants for pcrel
196 instructions only if the relocation type indicates a "call"
197 instruction and the offset is within range of a "jmpl %g0". If
198 it's not in range, use the absolute section symbol plus an offset.
199 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
201 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
203 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
206 * configure.in: Eliminated all targets using obj-coff but not
207 defining BFD_ASSEMBLER; I think all such targets that are
208 supported will be matched by real CPU-OS combinations earlier in
210 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
211 some comments about the dpx2 configuration, but left it disabled,
212 since it couldn't be reached before.
213 (target a29k-amd-ebmonold): Deleted.
215 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

223 the 'j' operand if there are no further alternatives for this
226 * config/obj-coffbfd.c (adjust_stab_section): Initialize
227 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
228 is not SEG_UNKNOWN rather than checking whether it is >= 0.
230 * config/tc-mips.c (mips_align): Take new argument, label, and use
231 it instead of global insn_label.
232 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
233 call to mips_emit_delay and pass it to mips_align.
235 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
237 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
239 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
240 argument to a .callinfo directive. Don't loop forever on errors.
242 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
243 use pre-defined registers as arguments.
245 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
247 * write.c (write_object_file): Check both S_IS_LOCAL and
248 S_IS_EXTERNAL when deciding whether to discard a symbol.
250 * config-gas.com: Scan Makefile.in, not version.c, for current
251 version number. Delete all versions of temp files when finished
252 with them. Create config.h.
254 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
255 values to reduce number of lookups with S_GET_VALUE. Skip debug

257 holger@botbso.rhein-main.de.)
258 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
259 field. (Also from Holger Teutsch.) Watch for a would-be register
260 mask that spans frags.
262 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
263 this_base, not line_base. (Patch from Andreas Arens,
264 ari@obelix.av.rwth-aachen.de.)
266 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
267 look local if they're exported or undefined. Used to be done for
270 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

274 (lex_type): Use it for `%'.
276 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2386 * config/tc-m68k.h: Don't define REGISTER_PREFIX or
2387 OPTIONAL_REGISTER_PREFIX if either is already defined.
2389 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
2391 * configure.in: Set bfd_gas for all sparc targets. Added facility
2392 for keeping or rejecting configurations still under development;
2393 default is to assume production environment, and reject configs
2394 still being worked on. Mark Elf configurations (except sparc and
2395 i386) as developmental. Deleted cases matching some generic names
2396 in favor of more specific names. (E.g., when we get Alpha
2397 support, we'll still only support VMS for Vax.)

2411 against placing additional object-file dependent code here. Warn
2412 against contaminating all of GAS with the internals of tc-hppa.c
2413 through inclusion of tc-hppa.h. Delete all forward declarations
2414 for functions only used within tc-hppa.c, likewise for structures,
2415 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2416 conditional code in a few small places.
2418 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2419 structures, global variables, forward declarations together.
2420 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2421 conditional code -- try to group conditional code together
2422 into a few places. Make all functions and variables which
2423 are only used within tc-hppa.c static. PARAMize all functions.
2424 Add comments to functions. Delete unused functions, variables,
2425 #defines, etc. Delete unused members within structures. Delete
2426 ldil;ble hacks -- it is believed they were installed to work
2427 around old gas bugs. Avoid using mixed case for local
2428 functions, variables, and structures. Fix formatting problems
2429 not found by GNU-indent. Add FIXME notices for things which
2430 should be worked on the near future. Delete lots of old
2431 useless (1.36 PA-SOM) code.

2443 which do not involve function symbols.
2445 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
2446 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
2448 * config/tc-hppa.c: Likewise.
2450 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2451 of elf32_symbol_type.
2452 (pa_export_args): Likewise.
2453 (elf_hppa_final_processing): Likewise.
2454 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

2459 * config/tc-hppa.c: (md_section_align): Align all sections to
2460 a multiple of the section alignment rather than always a
2463 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2464 bits are zero (eg they specify no relocations), then do not even
2465 bother adding their entries to thesymextn section.

2504 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2506 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2507 ELF, since the ELF object format does not have these type of
2508 relocations. Change the abort into as as_bad and return
2509 BFD_RELOC_NONE to silence compiler warnings.
2510 (md_assemble): Keep track of the instruction size. Allow white
2511 space between the $ and the constant for compatibility with older
2512 gases and other assemblers.

4849 dependencies are read, not when they are used).
4851 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4852 a29k .bss section; the mondfe program doesn't like it.

4873 source directory, if that's not the current directory.
4875 * configure.in (per-host): Accept MIPS host with BSD version

4897 process relocs if there aren't any relocs to process. Avoids
4898 malloc/free bug on SCO too.

4901 avoid some redefinition complaints on some systems.
4902 (const, volatile): Don't need these conditionally defined if we
4903 use CONST and VOLATILE from ansidecl.h.
4904 (seg_name): Use CONST, not const.
4906 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4908 * config/tc-mips.c: Reindented to GNU standards.

4912 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4913 (fixup_segment): Add a29k special case; the linker is not prepared
4914 to see a segment offset here.
4916 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4919 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4921 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4922 srcdir, might be in objdir.

4937 bignums, but don't emit error message.
4939 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4941 * Makefile.in (targ-cpu.o): Depend on config.h.
4943 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4945 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4946 dropping a space immediately following an identifier.
4947 * expr.c, write.c: Rewrote assert expressions to not use multiple
4948 lines; I don't think that can be done portably.
4949 * config/tc-mips.c (macro): Use $AT if target register is zero in
4950 load instruction, which it can be for a floating point load.
4952 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4973 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4975 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4976 to be on a single line.
4978 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5023 * config/tc-mips.c: Rearranged for ECOFF support. Added
5024 prototypes for all static functions. Moved existing minimal
5025 debugging format support info #ifndef OBJ_ECOFF blocks.

5074 * make-gas.com: Find obstack.obj if it's not in the current
5076 * read.c (s_ignore): Don't declare is_end_of_line. It's
5077 redundant, and triggers a VMS gcc compiler bug.
5079 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5080 current segment as an argument. (Ignored in all cases but VMS.)
5081 All callers and definitions changed.

5099 argument to s_ignore. Put "#if 0" around unused code.
5100 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5101 Call elf_xstabs for .stabs and .xstabs operators.
5103 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5105 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are

5111 * Makefile.in (Makefile): Depends on configure.in.
5113 * config/tc-mips.c (append_insn): Don't check for alignment of
5114 frag in memory; alignment of instructions in section is a separate

5378 md_relax_table): Use default zero initialization.
5379 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5380 latter, instead of selecting with preprocessor conditionals.
5382 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5384 * configure.in: recognise all sparclite variants

5394 * expr.c (operand): If character other than comma or newline is a
5395 logical end-of-line character, use the newline case.
5396 From Eric Youngdale:
5397 (operand): Set X_add_number field for floating-point numbers.
5398 (operand): Treat zero byte as end-of-operand.
5400 * configure.in (per-target): Look for with_bfd_assembler option.
5401 For now, only accept "no", until the merge is done.
5403 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5404 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5410 * expr.c: Add "const" modifier to hex_value.
5411 * symbols.c: Finish conversion to S_* macros in the VMS only
5412 parts of the program. Add "const" modifier to
5413 md_[long,short]_jump_size. Remove declaration of const_flag
5414 (which will be declared in obj-vms.h).
5415 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5416 Fix arguments to VMS_write_object_file.
5417 * config-gas.com: New file. Script for VMS systems to set up the
5418 configuration to build gas for VMS, and create config.status.
5419 * make-gas.com: Redone to work with new scheme.
5420 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

5425 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5426 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5427 types of malformed stabs. Change parsing algorithm so that we are
5428 more certain of having all of the information that we need on hand.
5429 * obj-vms.c (final_forward_reference): New function, used to help
5430 resolve the data types of as many struct elements as possible
5431 when some part of the struct is not fully defined by the compiler.

5434 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5435 as symbols as well in the object file. Look for external functions

5437 g++ compiler is incapable of doing this.
5438 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5440 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5441 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5442 have the name of the source file yet.
5443 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5445 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5447 * read.c (s_data): Always use "data_section", since it'll map to
5448 SEG_DATA or SEG_E1 if needed.
5449 (s_lcomm): Likewise with bss_section.
5450 (s_fill): Use memset, not bzero.
5452 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5474 (big_section, reg_section, pass1_section, diff_section,
5475 absent_section, text_section, data_section, bss_section): If
5476 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5477 mapping to segT enum values.
5478 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5479 if these are used or defined, if BFD_ASSEMBLER.
5480 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5481 subseg_new split into two functions.
5482 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5484 * as.h (volatile): Don't define if already defined.
5485 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5487 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5488 declare with format attribute for -Wformat checking.
5490 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5492 * app.c, config/tc-*.c: Don't include read.h, since it is already
5495 * These are based on patches from Minh Tran-le
5496 <mtranle@paris.intellicorp.com>.
5497 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5498 obj_format coffbfd and gas_target i386coff for target.
5499 (i[34]86-*-isc*): New host (uses sysv).
5500 * config/i386aix.mt: Removed (no longer used).
5501 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5503 (LDFLAGS): Added, defined as -shlib.
5504 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5505 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5506 (DOT_LABEL_PREFIX): Define.
5507 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5508 name rather than L0\001.
5509 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5511 * symbols.c, symbols.h (local_bss_counter): Removed.

5520 (size_section): Restored sanity check.
5521 (do_relocs_for): Base section address on s_paddr rather than
5522 computing it. Adjust a29k R_IHIHALF special case to account for
5523 section paddr (used to require paddr to be zero). If there are no
5524 reclos, set s_relptr to 0. Set relocation size in object_headers.
5525 (fill_section): Always set s_vaddr here, removing
5526 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5527 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5528 Set STYP_INFO for .comment.
5529 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5530 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5532 H_{SET,GET}_* macros.
5533 (do_linenos_for): Set lineno size in object_headers.
5534 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5535 set s_vaddr here. If string_byte_count remains 4, set it back to
5536 0, and only write strings out if there are some. Call
5537 fill_section before do_relocs_for and do_linenos_for.
5538 (obj_coff_section): Handle optional quoted second argument giving
5539 section characteristics.
5540 (obj_coff_bss): Added to handle .bss.
5541 (obj_coff_ident): Added to handle .ident (puts string in .comment

5561 (do_scrub_next_char): For \", return " not '.
5562 (symbol_chars): Now const.
5564 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5565 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5567 * config/obj-coff.h: Don't use #elif.
5569 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5570 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5572 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5574 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5594 SEG_BSS, fill with NOP_OPCODE.
5595 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5596 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5597 using ZERO_BASED_SEGMENTS.
5598 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5599 never set segment address for SEG_E2 (.bss) and don't write out
5600 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5601 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5602 definitions, and don't merge tags with non-tags. Check for .bf
5603 rather than just checking whether the second character is b and
5604 the third character is f.
5605 (obj_coff_val): gcc can generate values which we don't handle
5606 correctly; discard information for now, since it only affects the
5607 debugging information.
5608 (tag_find_or_name): Don't insert tags in the symbol table.

5756 could be doing emulation.
5758 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5761 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5790 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5792 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5793 constant will not fit in an immediate field.
5794 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5829 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5831 * Support for i386-sysv.
5832 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5872 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5874 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5875 #elif, since it is not supported by old compilers.
5876 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5877 couple of expressions in tc-m68k.c.
5879 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5881 * read.c (cons): If NO_RELOC is defined, use it.
5883 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5885 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5887 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5888 local labels to start with a .) and set REGISTER_PREFIX to %.
5889 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5891 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5905 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5907 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5908 sections starting from zero, rather than making them consecutive.
5909 This makes subsequent reloc calculations easier, esp if the object
5910 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5911 allocate lcomm in .data rather than in .bss. It seems that some
5912 tools can't cope with a non-zero sized bss before linkage.
5914 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5916 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5920 "-mno-688[58]1" options.
5922 * tc-m68k.c: Added CPU32 support.

5935 * Makefile.in (install): if $(tooldir) exists, install as in
5938 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5940 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5941 .word is < -32768 or > 32767. The -J flag causes the error to be
5942 ignored. This is to catch over-sized switches generated by gcc on
5943 systems which don't support the broken .word hack.
5944 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5945 write.c (fixup_segment): check for signed .word overflow if
5946 WARN_SIGNED_OVERFLOW_WORD.
5948 * write.c (fixup_segment): fixed missing parens in expression
5949 checking for byte or word overflow.
5951 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

5965 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5967 * input-scrub.c (input_scrub_push): call input_file_begin, not
5969 messages.c (as_perror): print ": " between the passed in error and
5970 the strerror, like perror does.

5975 From Steve Chamberlain:
5976 Makefile.in: Handle m68*-*-coff*.
5977 read.c, read.h: add mult argument to s_space
5979 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5980 Motorola and MIT syntax; gas can now assemble either type of

5989 (fixup_segment) set fx_subsy to 0.
5990 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5992 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5995 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5997 * Makefile.in (LIBS): Include opcode library.

6019 tc-i960.c (md_ri_to_chars): Always output bout object file in
6020 little endian byte order (used to use endianness of host).
6022 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6024 * config/tc-m68k.c (init_table): Now const. Always include 68851
6025 data, so that "bc" is available to 68040 cache instructions.
6026 Added "tt0", "tt1", and 68ec030 variants.
6027 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6028 (enum _register): Added TT0, TT1.
6029 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6030 line number correctly in "internal error" messages. Don't print
6031 architecture-mismatch message for operand errors.
6033 From Colin Smith (colin@wrs.com):
6034 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6035 than install_operand.
6037 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6039 * listing.c (buffer_line): rewind to the start of include
6040 files, they might be included twice.
6042 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
6044 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)

6049 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6051 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6052 so that we can assemble hand-written libgcc code.
6054 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6056 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6057 has already been formatted (but may still contain %-characters).
6060 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6062 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6063 written with indirection on the last two operands, which can be
6064 either data or address registers. Added a new operand type 'r'
6065 which accepts either register type. Added '(' to notend stuff in
6066 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6068 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6081 defined, call it. Change segments before calling fixup_segment.
6082 (relax_align): If linkrelax, provide extra padding.
6084 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6085 their not having symbols associated.
6087 * tc-i960.c (norelax, instrument_branches): Default initializer is
6089 (linkrelax): Delete variable definition.
6090 (mem_fmt): Call fix_new with NO_RELOC.

6178 characteristics have been), default to 68020. Don't need extra
6179 quotes around error string.

6263 * write.c (write_object_file): keep the fix_tail clean, which
6264 fixes a bug in -R where relocations were being lost.
6266 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6268 * configure.in: recognize m680x0 as having sun3 emulation mode for

6315 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6317 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6318 where gcc looks for it.
6320 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6322 * Makefile.in: Changed some lines to be less confusing for some

6388 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6390 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6392 * expr.c (operand): if can't work out what sort of operand it is,
6393 then look through FLT_CHARS for a hint.
6395 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6397 * Makefile.in, configure.in: removed traces of namesubdir,
6398 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6399 copyrights to '92, changed some from Cygnus to FSF.
6401 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6402 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6403 copyrights to '92, changed some from Cygnus to FSF.
6405 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6407 * expr.c: If an expression is single comma, then return with
6408 SEG_ABSENT rather than an error - since the sparc front end does
6409 really strange things with things like fbge,a
6411 * as.h: include bfd.h if using many sections
6412 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6413 local labels didn't work.
6414 * listing.c (list_symbol_table): don't core dump when there's no
6416 * write.c, write.h: call fix_new with the right number of args on
6418 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6421 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6423 * app.c: MRI compatibility - allow single quote to start a string.
6424 * as.c: fix typo recently introduced.
6425 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6426 * expr.c: Much rewriting, to accomodate MRI syntax for
6427 expressions. Also easier to read now.
6428 * listing.c: Put back defuns
6429 * read.c: modified to accept MRI syntax, put back listing pseudo
6430 ops so that an assembler built with NO_LISTING ignores list ops
6432 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6433 machine is a SPARC or a 29K.
6434 * config/obj-aout.c: added s_sect pseudo op
6435 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6436 fill in the timestamp.
6437 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6438 anymore, define all the relocs which the tc-<x> bit will use so we
6439 can translate from them to the coff types.
6440 * config/tc-a29k.c: reloc_type isn't ane enum any more
6441 * config/tc-m68k.c: Added NO_RELOC definition.
6443 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6445 * Makefile.in: put header files before C source for TAGS; remove
6446 references to non-existent syscalls.h.
6448 * read.c, write.c subsegs.c: back out the .bss changes.
6450 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6452 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6456 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6458 * symbols.c (local_label_name): symbols now start with ^A.
6460 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6461 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6462 generate these sections. .align: will use NOP_OPCODE or 0
6463 for padding. This is just for being nice to the
6466 * expr.c (operand): changed to generate local label "\001L0"
6467 starting with a ^A so that it is recognized as a local label.
6469 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6471 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6472 i/o opcodes - inb, inw, outb and outw. string manipulation with
6473 att syntax - scmp, slod, smov, ssca, ssto.
6475 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6476 to just after .file .
6478 In obj_crawl_symbol_chain() where it tries to put the external
6479 symbols apart, with the condition:
6480 (!S_IS_DEFINED(symbolP) &&
6481 !S_IS_DEBUG(symbolP) &&
6482 !SF_GET_STATICS(symbolP))
6483 it was moving too many symbols out. So I switch it back to the
6485 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6487 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6488 so that we don't use the F_RELFLG which make the linker complain
6489 that somebody has stripped the relocation info.
6491 Also, the AIX ld program require that the relocation table
6492 is sorted by r_vaddr like the standard ATT assembler does.
6494 [he also changed the sizeof(struct ...)'s into the coff
6495 style FOOSZ macros. I'm not sure this is right, but I can't
6496 remember why. xoxorich.]
6498 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6500 * Makefile.in, configure.in, doc: use the doc. Build it, install

6505 * read.c: white space and comments only.
6507 * configure.in: use the new atof-ns32.c for ns32k.
6509 * write.c: comment change only.
6511 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6512 aren't yet integrated.
6514 * tc-i860.[hc]: blew off the dust. Something must still be done
6515 about conflicting relocation types.
6517 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6520 * tc-i960.c, tc-sparc.c: white space and comments only.
6522 * tc-a29k.h: delete duplicate macro definition.
6524 * new file atof-ns32k.c copied from hack's last unreleased gas.
6526 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6528 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6531 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6532 ChangeLog's prior to this are sketchy at best. I have logs.
6533 They just aren't ChangeLogs.
6537 version-control: never
