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

45 don't spew remainder of input file in error message.
46 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
47 message with reloc type and try to process remainder of file.
49 * doc/Makefile.in (install-info-as, install-info-gasp): New
50 targets, now explicitly checking $(srcdir) for info files.

57 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
59 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
60 flag rather than signedp field. Only permit extended range if
61 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
62 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
64 * config/tc-ppc.c (ppc_size): New static variable.
65 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
66 (md_begin): If an instruction has a size specific flag set, only
67 add it if we are assembling that size.
69 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
71 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
72 cross section PC relative relocs right for COFF and ELF.

82 the type of symbol set symbols which happen to be in the absolute
85 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
87 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
88 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
89 and -many (all architectures).

100 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
102 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
103 branch with an instruction that uses $at, in case the branch is
105 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
106 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
107 to make it pcrel_offset.
108 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
109 reloc->address; another gruesome hack to get gas reloc handling to
112 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
114 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

121 (lituse_pending): New variable. Set by anything that generates a
122 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
123 tested by code that might want to emit a LITUSE reloc.
124 (emit_unaligned_io): New function. Currently calls md_assemble,
125 but it should eventually be converted to generate the insn itself
126 and call emit_insn directly.
127 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
128 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
129 emit_bis_r): Likewise.

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

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

176 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
178 * Makefile.in (config-stamp): If `defs' is defined, emit a
179 preprocessor directive to create a macro named by this value into
180 config.new; don't explicitly go for BFD_ASSEMBLER.
181 * configure.in: Define `defs', not `BFDDEF'. Set it to
182 MANY_SEGMENTS for any obj-coffbfd target.
183 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
184 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
186 (LOCAL_LOADLIBES): Deleted.
187 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
188 * config/m88kcoff.mt (TDEFINES): Ditto.

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

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

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

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

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

2445 default is to assume production environment, and reject configs
2446 still being worked on. Mark Elf configurations (except sparc and
2447 i386) as developmental. Deleted cases matching some generic names
2448 in favor of more specific names. (E.g., when we get Alpha

2466 for functions only used within tc-hppa.c, likewise for structures,
2467 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2468 conditional code in a few small places.
2470 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2471 structures, global variables, forward declarations together.

2474 into a few places. Make all functions and variables which
2475 are only used within tc-hppa.c static. PARAMize all functions.
2476 Add comments to functions. Delete unused functions, variables,
2477 #defines, etc. Delete unused members within structures. Delete
2478 ldil;ble hacks -- it is believed they were installed to work
2479 around old gas bugs. Avoid using mixed case for local
2480 functions, variables, and structures. Fix formatting problems
2481 not found by GNU-indent. Add FIXME notices for things which
2482 should be worked on the near future. Delete lots of old
2483 useless (1.36 PA-SOM) code.

2500 * config/tc-hppa.c: Likewise.
2502 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2503 of elf32_symbol_type.
2504 (pa_export_args): Likewise.
2505 (elf_hppa_final_processing): Likewise.

2512 a multiple of the section alignment rather than always a
2515 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2556 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2558 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2559 ELF, since the ELF object format does not have these type of
2560 relocations. Change the abort into as as_bad and return
2561 BFD_RELOC_NONE to silence compiler warnings.
2562 (md_assemble): Keep track of the instruction size. Allow white
2563 space between the $ and the constant for compatibility with older
2564 gases and other assemblers.

4904 a29k .bss section; the mondfe program doesn't like it.

4925 source directory, if that's not the current directory.
4927 * configure.in (per-host): Accept MIPS host with BSD version

4953 avoid some redefinition complaints on some systems.
4954 (const, volatile): Don't need these conditionally defined if we
4955 use CONST and VOLATILE from ansidecl.h.
4956 (seg_name): Use CONST, not const.
4958 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4960 * config/tc-mips.c: Reindented to GNU standards.

4964 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4965 (fixup_segment): Add a29k special case; the linker is not prepared
4966 to see a segment offset here.
4968 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4971 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4973 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4974 srcdir, might be in objdir.
4976 * doc/Makefile.in: dvi depends on as.dvi

4993 * Makefile.in (targ-cpu.o): Depend on config.h.
4995 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4997 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4998 dropping a space immediately following an identifier.
4999 * expr.c, write.c: Rewrote assert expressions to not use multiple
5000 lines; I don't think that can be done portably.
5001 * config/tc-mips.c (macro): Use $AT if target register is zero in
5002 load instruction, which it can be for a floating point load.
5004 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5021 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

5025 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5027 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5028 to be on a single line.
5030 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5032 * Makefile.in (config.h): Create file, writing out definitions of

5075 * config/tc-mips.c: Rearranged for ECOFF support. Added
5076 prototypes for all static functions. Moved existing minimal
5077 debugging format support info #ifndef OBJ_ECOFF blocks.

5126 * make-gas.com: Find obstack.obj if it's not in the current
5128 * read.c (s_ignore): Don't declare is_end_of_line. It's
5129 redundant, and triggers a VMS gcc compiler bug.
5131 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5132 current segment as an argument. (Ignored in all cases but VMS.)
5133 All callers and definitions changed.
5135 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
5137 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING

5149 (obj_elf_xstab): New routine.
5150 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
5151 argument to s_ignore. Put "#if 0" around unused code.
5152 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5153 Call elf_xstabs for .stabs and .xstabs operators.
5155 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".

5430 md_relax_table): Use default zero initialization.
5431 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5432 latter, instead of selecting with preprocessor conditionals.
5434 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5436 * configure.in: recognise all sparclite variants

5446 * expr.c (operand): If character other than comma or newline is a
5447 logical end-of-line character, use the newline case.
5448 From Eric Youngdale:
5449 (operand): Set X_add_number field for floating-point numbers.
5450 (operand): Treat zero byte as end-of-operand.
5452 * configure.in (per-target): Look for with_bfd_assembler option.
5453 For now, only accept "no", until the merge is done.
5455 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5456 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5462 * expr.c: Add "const" modifier to hex_value.
5463 * symbols.c: Finish conversion to S_* macros in the VMS only
5464 parts of the program. Add "const" modifier to
5465 md_[long,short]_jump_size. Remove declaration of const_flag
5466 (which will be declared in obj-vms.h).
5467 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5468 Fix arguments to VMS_write_object_file.
5469 * config-gas.com: New file. Script for VMS systems to set up the
5470 configuration to build gas for VMS, and create config.status.
5471 * make-gas.com: Redone to work with new scheme.
5472 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

5477 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5478 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5479 types of malformed stabs. Change parsing algorithm so that we are
5480 more certain of having all of the information that we need on hand.
5481 * obj-vms.c (final_forward_reference): New function, used to help
5482 resolve the data types of as many struct elements as possible
5483 when some part of the struct is not fully defined by the compiler.

5486 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5487 as symbols as well in the object file. Look for external functions

5490 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5492 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

5500 SEG_DATA or SEG_E1 if needed.
5501 (s_lcomm): Likewise with bss_section.
5502 (s_fill): Use memset, not bzero.
5504 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5527 absent_section, text_section, data_section, bss_section): If
5528 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5529 mapping to segT enum values.
5530 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5531 if these are used or defined, if BFD_ASSEMBLER.
5532 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5533 subseg_new split into two functions.
5534 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5536 * as.h (volatile): Don't define if already defined.
5537 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5539 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5540 declare with format attribute for -Wformat checking.
5542 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5544 * app.c, config/tc-*.c: Don't include read.h, since it is already

5548 <mtranle@paris.intellicorp.com>.
5549 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use

5557 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5558 (DOT_LABEL_PREFIX): Define.
5559 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5560 name rather than L0\001.
5561 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5563 * symbols.c, symbols.h (local_bss_counter): Removed.
5564 * write.c (write_object_file): bss no longer uses

5572 (size_section): Restored sanity check.
5573 (do_relocs_for): Base section address on s_paddr rather than
5574 computing it. Adjust a29k R_IHIHALF special case to account for

5576 reclos, set s_relptr to 0. Set relocation size in object_headers.
5577 (fill_section): Always set s_vaddr here, removing
5578 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5579 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5580 Set STYP_INFO for .comment.
5581 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5582 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5584 H_{SET,GET}_* macros.
5585 (do_linenos_for): Set lineno size in object_headers.
5586 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5587 set s_vaddr here. If string_byte_count remains 4, set it back to
5588 0, and only write strings out if there are some. Call
5589 fill_section before do_relocs_for and do_linenos_for.
5590 (obj_coff_section): Handle optional quoted second argument giving
5591 section characteristics.
5592 (obj_coff_bss): Added to handle .bss.
5593 (obj_coff_ident): Added to handle .ident (puts string in .comment

5613 (do_scrub_next_char): For \", return " not '.
5614 (symbol_chars): Now const.
5616 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5617 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5619 * config/obj-coff.h: Don't use #elif.
5621 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5622 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5652 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5653 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5654 definitions, and don't merge tags with non-tags. Check for .bf
5655 rather than just checking whether the second character is b and
5656 the third character is f.
5657 (obj_coff_val): gcc can generate values which we don't handle

5661 (yank_symbols): Don't merge labels.
5662 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5774 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
5776 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
5779 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
5781 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

5807 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5808 could be doing emulation.
5810 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5813 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
5816 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

5842 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5844 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5845 constant will not fit in an immediate field.
5846 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5881 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5883 * Support for i386-sysv.
5884 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5922 * tc-z8k.c: lots of bug fixes
5924 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5926 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5927 #elif, since it is not supported by old compilers.
5928 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5929 couple of expressions in tc-m68k.c.
5931 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5933 * read.c (cons): If NO_RELOC is defined, use it.
5935 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5937 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5939 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5940 local labels to start with a .) and set REGISTER_PREFIX to %.
5941 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5943 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5954 * listing.c (debugging_pseudo): Add stabs and stabn as things to
5957 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5959 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5960 sections starting from zero, rather than making them consecutive.
5961 This makes subsequent reloc calculations easier, esp if the object
5962 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5963 allocate lcomm in .data rather than in .bss. It seems that some
5964 tools can't cope with a non-zero sized bss before linkage.
5966 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5968 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5969 throughout. That enum no longer means what we thought it meant.

5972 "-mno-688[58]1" options.
5974 * tc-m68k.c: Added CPU32 support.

5987 * Makefile.in (install): if $(tooldir) exists, install as in
5990 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5992 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5993 .word is < -32768 or > 32767. The -J flag causes the error to be
5994 ignored. This is to catch over-sized switches generated by gcc on
5995 systems which don't support the broken .word hack.
5996 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5997 write.c (fixup_segment): check for signed .word overflow if
5998 WARN_SIGNED_OVERFLOW_WORD.
6000 * write.c (fixup_segment): fixed missing parens in expression
6001 checking for byte or word overflow.

6017 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6019 * input-scrub.c (input_scrub_push): call input_file_begin, not
6021 messages.c (as_perror): print ": " between the passed in error and
6022 the strerror, like perror does.
6024 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

6040 (write_object_file) call fixup_mdeps
6041 (fixup_segment) set fx_subsy to 0.
6042 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6044 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6047 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6049 * Makefile.in (LIBS): Include opcode library.
6051 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6071 tc-i960.c (md_ri_to_chars): Always output bout object file in
6072 little endian byte order (used to use endianness of host).
6074 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6076 * config/tc-m68k.c (init_table): Now const. Always include 68851
6077 data, so that "bc" is available to 68040 cache instructions.
6078 Added "tt0", "tt1", and 68ec030 variants.
6079 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6080 (enum _register): Added TT0, TT1.
6081 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6082 line number correctly in "internal error" messages. Don't print
6083 architecture-mismatch message for operand errors.
6085 From Colin Smith (colin@wrs.com):
6086 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6087 than install_operand.

6099 one element of a family.
6101 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6103 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6104 so that we can assemble hand-written libgcc code.
6106 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6108 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6109 has already been formatted (but may still contain %-characters).
6112 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6114 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6115 written with indirection on the last two operands, which can be
6116 either data or address registers. Added a new operand type 'r'
6117 which accepts either register type. Added '(' to notend stuff in
6118 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6230 characteristics have been), default to 68020. Don't need extra
6231 quotes around error string.

6315 * write.c (write_object_file): keep the fix_tail clean, which
6316 fixes a bug in -R where relocations were being lost.
6318 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6320 * configure.in: recognize m680x0 as having sun3 emulation mode for

6364 * write.c (write_object_file): For b.out format, round up section
6365 start addresses to match required alignment.
6367 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6369 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6370 where gcc looks for it.
6372 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6374 * Makefile.in: Changed some lines to be less confusing for some

6440 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6442 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6444 * expr.c (operand): if can't work out what sort of operand it is,
6445 then look through FLT_CHARS for a hint.
6447 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6449 * Makefile.in, configure.in: removed traces of namesubdir,

6451 copyrights to '92, changed some from Cygnus to FSF.
6453 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6454 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6455 copyrights to '92, changed some from Cygnus to FSF.
6457 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6459 * expr.c: If an expression is single comma, then return with
6460 SEG_ABSENT rather than an error - since the sparc front end does
6461 really strange things with things like fbge,a
6463 * as.h: include bfd.h if using many sections
6464 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6465 local labels didn't work.
6466 * listing.c (list_symbol_table): don't core dump when there's no
6468 * write.c, write.h: call fix_new with the right number of args on
6470 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6473 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6475 * app.c: MRI compatibility - allow single quote to start a string.
6476 * as.c: fix typo recently introduced.
6477 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6478 * expr.c: Much rewriting, to accomodate MRI syntax for
6479 expressions. Also easier to read now.
6480 * listing.c: Put back defuns
6481 * read.c: modified to accept MRI syntax, put back listing pseudo
6482 ops so that an assembler built with NO_LISTING ignores list ops
6484 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6485 machine is a SPARC or a 29K.
6486 * config/obj-aout.c: added s_sect pseudo op
6487 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6488 fill in the timestamp.
6489 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6490 anymore, define all the relocs which the tc-<x> bit will use so we
6491 can translate from them to the coff types.
6492 * config/tc-a29k.c: reloc_type isn't ane enum any more
6493 * config/tc-m68k.c: Added NO_RELOC definition.
6495 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6497 * Makefile.in: put header files before C source for TAGS; remove
6498 references to non-existent syscalls.h.
6500 * read.c, write.c subsegs.c: back out the .bss changes.
6502 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6504 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6508 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6510 * symbols.c (local_label_name): symbols now start with ^A.
6512 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6513 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6514 generate these sections. .align: will use NOP_OPCODE or 0
6515 for padding. This is just for being nice to the
6518 * expr.c (operand): changed to generate local label "\001L0"
6519 starting with a ^A so that it is recognized as a local label.
6521 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6523 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6524 i/o opcodes - inb, inw, outb and outw. string manipulation with
6525 att syntax - scmp, slod, smov, ssca, ssto.
6527 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6528 to just after .file .
6530 In obj_crawl_symbol_chain() where it tries to put the external
6531 symbols apart, with the condition:
6532 (!S_IS_DEFINED(symbolP) &&
6533 !S_IS_DEBUG(symbolP) &&
6534 !SF_GET_STATICS(symbolP))
6535 it was moving too many symbols out. So I switch it back to the
6537 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6539 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6540 so that we don't use the F_RELFLG which make the linker complain
6541 that somebody has stripped the relocation info.
6543 Also, the AIX ld program require that the relocation table
6544 is sorted by r_vaddr like the standard ATT assembler does.
6546 [he also changed the sizeof(struct ...)'s into the coff
6547 style FOOSZ macros. I'm not sure this is right, but I can't
6548 remember why. xoxorich.]
6550 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

6557 * read.c: white space and comments only.
6559 * configure.in: use the new atof-ns32.c for ns32k.
6561 * write.c: comment change only.
6563 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6564 aren't yet integrated.
6566 * tc-i860.[hc]: blew off the dust. Something must still be done
6567 about conflicting relocation types.
6569 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6572 * tc-i960.c, tc-sparc.c: white space and comments only.
6574 * tc-a29k.h: delete duplicate macro definition.
6576 * new file atof-ns32k.c copied from hack's last unreleased gas.
6578 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6580 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6583 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6584 ChangeLog's prior to this are sketchy at best. I have logs.
6585 They just aren't ChangeLogs.
6589 version-control: never
