3 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
4 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
5 the header with an empty list.

19 and bfd_ecoff_set_regmasks to set the GP value and the register
20 masks, rather than using the now obsolete fake .reginfo section.
22 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
24 * listing.c (list_symbol_table): Don't print register symbols as
27 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
28 underscores, since symbol_new will already have done it.
29 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
31 * as.c (main): If tc_init_after_args is defined, invoke it after
32 all arguments have been processed.
34 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
35 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
36 section instead of .text. Call create_target_segments.
37 * read.c (demand_copy_string): No longer static.
39 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
41 * config/tc-mips.c (append_insn): Permit branches to be switched
42 with the preceding instruction even if .set nobopt has been seen.
43 .set nobopt actually controls whether to bring up an instruction
44 from the branch target, which gas does not currently support.

61 * config/tc-sparc.c (md_section_align): Always round up to
62 multiple of alignment power specified in bfd target vector.
64 * gasp.c: Include ctype.h.

85 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
86 defaults for defined, private, and spnum fields for the
87 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
88 not reset the segment if just updating a space.
89 (pa_spaces_begin): Set BFD section flags for all built-in
92 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

95 (add_procedure): Set first_proc_ptr if it hasn't been set.
96 (ecoff_build_lineno): If the first procedure does not start at
97 address zero, insert a dummy line to compensate.
99 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
102 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
104 * expr.c (operand): Try to parse "0f" and "0b" sequences as
105 floating point and binary numbers respectively; if it doesn't
106 work, treat them as local labels.
108 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
109 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
111 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
113 * vmsconf.sh: In generated file, get ".obj" suffix right, build
114 source files from other directories into objects in the current
115 directory, and specify PSECT attributes explicitly to linker.
116 Also added missing label.
117 * Makefile.in (stamp-mk.com): Reference new variable
118 VMS_OTHER_OBJS for list of non-local object files, instead of
120 (VMS_OTHER_OBJS): New variable, added more libiberty files.
121 * make-gas.com: Regenerated.
123 * config/ho-vms.h (unlink): Define as delete.
125 * config-gas.com: Fix quoting on TARGET_CANONICAL definition.

133 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
134 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
135 argument, the reloc type.
136 (load_register): Pass reloc type to macro_build for 'u'.
137 (macro): Likewise. For M_LA_AB permit a difference expression
138 when generating embedded PIC code between an arbitrary symbol and
139 a symbol in the .text section.
140 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
141 BFD_RELOC_PCREL_LO16 to be emitted.
142 (md_apply_fix): Check that most relocs are not PC relative.
143 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.
144 (tc_gen_reloc): Change #error to as_fatal. Handle
145 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.
147 Tue Apr 12 18:25:13 1994 Stan Shebs (shebs@andros.cygnus.com)
149 * subsegs.c (subsegs_begin): Call memset with args in the correct
151 (subseg_get): Clear newly allocated seginfo, set its pointer slots
152 to NULL instead of 0.
154 Mon Apr 11 09:00:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
156 * config/tc-hppa.c (pa_procend): Handle case where label was
157 defined after the .proc directive.
159 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
160 procend for a procedure without a name.

181 (hppa_tc_symbol): Likewise.
183 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
184 elf_tc_make_sections stuff. It was there to support PA braindamage
185 which has been fixed, and in the case of elf_tc_make_sections is
186 redundant with elf_tc_final_processing.
188 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
190 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

200 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
201 value into the file if the fixup will not generate a reloc.
203 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
205 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
206 don't spew remainder of input file in error message.
207 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
208 message with reloc type and try to process remainder of file.
210 * doc/Makefile.in (install-info-as, install-info-gasp): New
211 targets, now explicitly checking $(srcdir) for info files.
212 (install-info): Depend on both of them; do nothing more.
214 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
216 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
218 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
220 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
221 flag rather than signedp field. Only permit extended range if
222 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
223 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
225 * config/tc-ppc.c (ppc_size): New static variable.
226 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
227 (md_begin): If an instruction has a size specific flag set, only
228 add it if we are assembling that size.
230 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
232 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
233 cross section PC relative relocs right for COFF and ELF.
235 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
237 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
238 (OBJ_PROCESS_STAB): Don't define.
240 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
242 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
243 the type of symbol set symbols which happen to be in the absolute
244 or undefined section.
246 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
248 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
249 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
250 and -many (all architectures).
252 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

258 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
260 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
261 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
263 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
264 branch with an instruction that uses $at, in case the branch is
266 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
267 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
268 to make it pcrel_offset.
269 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
270 reloc->address; another gruesome hack to get gas reloc handling to
273 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
275 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
278 (emit_insn): New function.
279 (md_assemble): Call it.
280 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
282 (lituse_pending): New variable. Set by anything that generates a
283 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
284 tested by code that might want to emit a LITUSE reloc.
285 (emit_unaligned_io): New function. Currently calls md_assemble,
286 but it should eventually be converted to generate the insn itself
287 and call emit_insn directly.
288 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
289 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
290 emit_bis_r): Likewise.
291 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
292 (alpha_ip, label get_macro): Don't emit the final instruction if
294 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
295 unaligned memory access macros.

297 the value can't be resolved.
299 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
301 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
302 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
303 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
305 (mips_force_relocation): New function.
306 (md_apply_fix): Set fixP->fx_done appropriately.
307 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

315 * config/tc-mips.c (enum mips_pic_level): New enum.
316 (mips_pic): Change from int to enum mips_pic_level. Change all
317 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
318 (load_address): Handle EMBEDDED_PIC.
319 (macro): Handle EMBEDDED_PIC in all PIC cases.
320 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
321 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
322 -non_shared to use NO_PIC (this is how the Irix 5 assembler
323 works). Do not permit -G with SVR4_PIC.
324 (s_abicalls): Warn if -G was used, and force -G 0.
325 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
326 anything but a.out, not just for ELF. For ECOFF, don't generate a
327 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
329 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
331 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
333 * config/tc-hppa.c (create_new_space): Use ints, not chars as
334 parameters to avoid losing when compiling with HP CC.
335 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
337 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
339 * Makefile.in (config-stamp): If `defs' is defined, emit a
340 preprocessor directive to create a macro named by this value into
341 config.new; don't explicitly go for BFD_ASSEMBLER.
342 * configure.in: Define `defs', not `BFDDEF'. Set it to
343 MANY_SEGMENTS for any obj-coffbfd target.
344 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
345 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
347 (LOCAL_LOADLIBES): Deleted.
348 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
349 * config/m88kcoff.mt (TDEFINES): Ditto.
350 * config/ebmon29k.mt: Deleted.
351 * config/h8300hds.mt: Deleted.
352 * config/ic960coff.mt: Deleted.
353 * config/sparc.mt: Deleted.
354 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
355 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
356 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
357 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

375 bfd_set_symtab is called.
376 (dump_section_relocs): Note whether a symbol is a section symbol
378 (adjust_reloc_syms): For now, always supply an absolute symbol for
379 fixups without symbols but not yet `done'. Use section_symbol to
380 get the symbol, instead of going directly for abs_symbol.
381 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
382 reloc is not a section symbol and is not in the symbol table.
383 (set_symtab): New function, broken out from write_object_file.
384 Counts symbol table instead of relying on an earlier count.
385 (write_object_file): Call set_symtab, but do it after potentially
386 invoking the *_frob_file macros. Don't bother counting symbols.
387 Call symbol_remove, instead of expanding it in place. Moved the
388 conditionalized `object_file_size' declaration down to
389 conditionalized block where it's used. When using the absolute
390 symbol for a fixup without a symbol, set sy_used_in_reloc.
391 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
392 the correct symbol for the absolute section.
394 * subsegs.c (section_symbol): Use symbol_new instead of
395 symbol_make, since we may want it to go into the symbol table.
396 Make the new symbol have internal linkage. If
397 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
398 symbol with the newly created GAS symbol.
399 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
400 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
402 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
404 * config/tc-sparc.c: Include subsegs.h.
405 (in_signed_range): New function.
407 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
408 (sparc_ip, label "immediate"): Reject constants for pcrel
409 instructions only if the relocation type indicates a "call"
410 instruction and the offset is within range of a "jmpl %g0". If
411 it's not in range, use the absolute section symbol plus an offset.
412 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
414 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
416 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
419 * configure.in: Eliminated all targets using obj-coff but not
420 defining BFD_ASSEMBLER; I think all such targets that are
421 supported will be matched by real CPU-OS combinations earlier in
423 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
424 some comments about the dpx2 configuration, but left it disabled,
425 since it couldn't be reached before.
426 (target a29k-amd-ebmonold): Deleted.
428 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
430 * config/tc-hppa.c (pa_import): Correctly handle importing of an
431 already defined symbol.
433 Wed Mar 16 17:11:37 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
435 * config/tc-mips.c (mips_ip): Only accept overly large values for
436 the 'j' operand if there are no further alternatives for this
439 * config/obj-coffbfd.c (adjust_stab_section): Initialize
440 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
441 is not SEG_UNKNOWN rather than checking whether it is >= 0.
443 * config/tc-mips.c (mips_align): Take new argument, label, and use
444 it instead of global insn_label.
445 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
446 call to mips_emit_delay and pass it to mips_align.
448 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
450 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
452 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
453 argument to a .callinfo directive. Don't loop forever on errors.
455 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
456 use pre-defined registers as arguments.
458 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
460 * write.c (write_object_file): Check both S_IS_LOCAL and
461 S_IS_EXTERNAL when deciding whether to discard a symbol.
463 * config-gas.com: Scan Makefile.in, not version.c, for current
464 version number. Delete all versions of temp files when finished
465 with them. Create config.h.
467 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
468 values to reduce number of lookups with S_GET_VALUE. Skip debug
469 symbols to avoid "a really nasty bug". (From Holger Teutsch,
470 holger@botbso.rhein-main.de.)
471 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
472 field. (Also from Holger Teutsch.) Watch for a would-be register
473 mask that spans frags.
475 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with

2198 empty string case like the HP assembler -- assume a value of
2201 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
2202 standard hpux include files to pick up various function decls.
2204 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

2218 descriptor information to the BFD symbol.
2219 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

2238 an example of marker relocations.
2239 * write.c (write_relocs): Instead of assuming size of a relocation
2240 is 4 bytes, pick up the size from relocation itself.

2270 pass new argument for i, j and o cases.
2271 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2605 for keeping or rejecting configurations still under development;
2606 default is to assume production environment, and reject configs
2607 still being worked on. Mark Elf configurations (except sparc and
2608 i386) as developmental. Deleted cases matching some generic names
2609 in favor of more specific names. (E.g., when we get Alpha

2626 through inclusion of tc-hppa.h. Delete all forward declarations
2627 for functions only used within tc-hppa.c, likewise for structures,
2628 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2629 conditional code in a few small places.
2631 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2632 structures, global variables, forward declarations together.

2634 conditional code -- try to group conditional code together
2635 into a few places. Make all functions and variables which
2636 are only used within tc-hppa.c static. PARAMize all functions.
2637 Add comments to functions. Delete unused functions, variables,
2638 #defines, etc. Delete unused members within structures. Delete
2639 ldil;ble hacks -- it is believed they were installed to work
2640 around old gas bugs. Avoid using mixed case for local
2641 functions, variables, and structures. Fix formatting problems
2642 not found by GNU-indent. Add FIXME notices for things which
2643 should be worked on the near future. Delete lots of old
2644 useless (1.36 PA-SOM) code.

2717 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2719 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2720 ELF, since the ELF object format does not have these type of
2721 relocations. Change the abort into as as_bad and return
2722 BFD_RELOC_NONE to silence compiler warnings.
2723 (md_assemble): Keep track of the instruction size. Allow white
2724 space between the $ and the constant for compatibility with older
2725 gases and other assemblers.
2726 (i386_operand): Skip spaces between $ and expression.

3736 * expr.c (expr): Don't let absolute_section override
3737 undefined_section for the return value.
3739 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3740 pseudo-op with a poc_handler field of NULL, ignore it and treat it
3741 as an instruction instead.
3742 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
3745 * config/tc-h8500.c (md_begin): Use a local variable when

3757 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3758 case to set obj_format=elf. Must go before i386-*-sysv* case that
3759 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3760 *-*-solaris case, and move to before *-sysv* case that wants to
3761 set obj_format to coff.

3787 * Extensive changes to permit symbols to contain any expression
3788 type and to delay the computation of the expression until the
3789 value is actually needed. This permits setting symbols to values
3790 calculated based on object code size. Expressions were changed to
3791 no longer be in a section, to stop the overloading of segment and
3792 expression type that previously occurred.
3794 * as.c (big_section, pass1_section, diff_section, absent_section):
3796 (expr_section): Added (used for dummy symbols which hold

3880 (previous_section, previous_subsection): New vars.
3881 (obj_elf_section): Save current place in case DWARF code wants us
3882 to pop back to it. Handle unquoted section name as well as quoted
3883 section name. Don't crash on invalid strings.
3884 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3887 * config/obj-elf.h: Don't include struc-symbol.h.

3996 sy_resolved and sy_resolving single bit fields.
3997 * symbols.c (symbol_new): Don't initialize sy_forward field.

5159 dropping a space immediately following an identifier.
5160 * expr.c, write.c: Rewrote assert expressions to not use multiple
5161 lines; I don't think that can be done portably.
5162 * config/tc-mips.c (macro): Use $AT if target register is zero in
5163 load instruction, which it can be for a floating point load.

5237 prototypes for all static functions. Moved existing minimal
5238 debugging format support info #ifndef OBJ_ECOFF blocks.

5289 * read.c (s_ignore): Don't declare is_end_of_line. It's
5290 redundant, and triggers a VMS gcc compiler bug.
5292 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5293 current segment as an argument. (Ignored in all cases but VMS.)
5294 All callers and definitions changed.

5638 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5639 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5640 types of malformed stabs. Change parsing algorithm so that we are
5641 more certain of having all of the information that we need on hand.
5642 * obj-vms.c (final_forward_reference): New function, used to help
5643 resolve the data types of as many struct elements as possible
5644 when some part of the struct is not fully defined by the compiler.
5645 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5647 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5648 as symbols as well in the object file. Look for external functions
5649 that start with "__vt.", and turn them into variables, since the
5650 g++ compiler is incapable of doing this.
5651 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5653 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5654 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5655 have the name of the source file yet.

5658 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5660 * read.c (s_data): Always use "data_section", since it'll map to
5661 SEG_DATA or SEG_E1 if needed.
5662 (s_lcomm): Likewise with bss_section.
5663 (s_fill): Use memset, not bzero.
5665 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5681 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5682 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5687 (big_section, reg_section, pass1_section, diff_section,
5688 absent_section, text_section, data_section, bss_section): If
5689 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5690 mapping to segT enum values.
5691 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5692 if these are used or defined, if BFD_ASSEMBLER.
5693 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5694 subseg_new split into two functions.
5695 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5697 * as.h (volatile): Don't define if already defined.
5698 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5700 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5701 declare with format attribute for -Wformat checking.
5703 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5705 * app.c, config/tc-*.c: Don't include read.h, since it is already
5708 * These are based on patches from Minh Tran-le
5709 <mtranle@paris.intellicorp.com>.
5710 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5711 obj_format coffbfd and gas_target i386coff for target.
5712 (i[34]86-*-isc*): New host (uses sysv).
5713 * config/i386aix.mt: Removed (no longer used).
5714 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5716 (LDFLAGS): Added, defined as -shlib.
5717 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5718 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5719 (DOT_LABEL_PREFIX): Define.
5720 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5721 name rather than L0\001.
5722 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5724 * symbols.c, symbols.h (local_bss_counter): Removed.

5733 (size_section): Restored sanity check.
5734 (do_relocs_for): Base section address on s_paddr rather than
5735 computing it. Adjust a29k R_IHIHALF special case to account for
5736 section paddr (used to require paddr to be zero). If there are no
5737 reclos, set s_relptr to 0. Set relocation size in object_headers.
5738 (fill_section): Always set s_vaddr here, removing
5739 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5740 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5741 Set STYP_INFO for .comment.

5745 H_{SET,GET}_* macros.
5746 (do_linenos_for): Set lineno size in object_headers.
5747 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5748 set s_vaddr here. If string_byte_count remains 4, set it back to
5749 0, and only write strings out if there are some. Call
5750 fill_section before do_relocs_for and do_linenos_for.
5751 (obj_coff_section): Handle optional quoted second argument giving
5752 section characteristics.
5753 (obj_coff_bss): Added to handle .bss.
5754 (obj_coff_ident): Added to handle .ident (puts string in .comment

5774 (do_scrub_next_char): For \", return " not '.
5775 (symbol_chars): Now const.
5777 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5778 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5780 * config/obj-coff.h: Don't use #elif.
5782 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5783 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5812 never set segment address for SEG_E2 (.bss) and don't write out
5813 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5814 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5815 definitions, and don't merge tags with non-tags. Check for .bf
5816 rather than just checking whether the second character is b and
5817 the third character is f.
5818 (obj_coff_val): gcc can generate values which we don't handle
5819 correctly; discard information for now, since it only affects the
5820 debugging information.

5822 (yank_symbols): Don't merge labels.
5823 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6120 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6121 sections starting from zero, rather than making them consecutive.
6122 This makes subsequent reloc calculations easier, esp if the object
6123 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6124 allocate lcomm in .data rather than in .bss. It seems that some
6125 tools can't cope with a non-zero sized bss before linkage.
6127 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6129 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6130 throughout. That enum no longer means what we thought it meant.

6151 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6153 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6154 .word is < -32768 or > 32767. The -J flag causes the error to be
6155 ignored. This is to catch over-sized switches generated by gcc on
6156 systems which don't support the broken .word hack.
6157 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6158 write.c (fixup_segment): check for signed .word overflow if
6159 WARN_SIGNED_OVERFLOW_WORD.

6188 From Steve Chamberlain:
6189 Makefile.in: Handle m68*-*-coff*.
6190 read.c, read.h: add mult argument to s_space
6192 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge

6203 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6205 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6208 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6210 * Makefile.in (LIBS): Include opcode library.

6237 * config/tc-m68k.c (init_table): Now const. Always include 68851
6238 data, so that "bc" is available to 68040 cache instructions.
6239 Added "tt0", "tt1", and 68ec030 variants.
6240 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6241 (enum _register): Added TT0, TT1.
6242 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6243 line number correctly in "internal error" messages. Don't print
6244 architecture-mismatch message for operand errors.

6269 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6270 has already been formatted (but may still contain %-characters).
6273 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6275 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6276 written with indirection on the last two operands, which can be
6277 either data or address registers. Added a new operand type 'r'
6278 which accepts either register type. Added '(' to notend stuff in
6279 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6612 copyrights to '92, changed some from Cygnus to FSF.
6614 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6615 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6616 copyrights to '92, changed some from Cygnus to FSF.

6620 * expr.c: If an expression is single comma, then return with
6621 SEG_ABSENT rather than an error - since the sparc front end does
6622 really strange things with things like fbge,a
6624 * as.h: include bfd.h if using many sections
6625 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6626 local labels didn't work.
6627 * listing.c (list_symbol_table): don't core dump when there's no
6629 * write.c, write.h: call fix_new with the right number of args on
6631 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6634 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6636 * app.c: MRI compatibility - allow single quote to start a string.
6637 * as.c: fix typo recently introduced.
6638 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6639 * expr.c: Much rewriting, to accomodate MRI syntax for
6640 expressions. Also easier to read now.
6641 * listing.c: Put back defuns
6642 * read.c: modified to accept MRI syntax, put back listing pseudo
6643 ops so that an assembler built with NO_LISTING ignores list ops
6645 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6646 machine is a SPARC or a 29K.
6647 * config/obj-aout.c: added s_sect pseudo op
6648 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6649 fill in the timestamp.
6650 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6651 anymore, define all the relocs which the tc-<x> bit will use so we
6652 can translate from them to the coff types.
6653 * config/tc-a29k.c: reloc_type isn't ane enum any more
6654 * config/tc-m68k.c: Added NO_RELOC definition.
6656 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6658 * Makefile.in: put header files before C source for TAGS; remove
6659 references to non-existent syscalls.h.
6661 * read.c, write.c subsegs.c: back out the .bss changes.
6663 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6665 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6669 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6671 * symbols.c (local_label_name): symbols now start with ^A.
6673 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6674 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6675 generate these sections. .align: will use NOP_OPCODE or 0
6676 for padding. This is just for being nice to the
6679 * expr.c (operand): changed to generate local label "\001L0"
6680 starting with a ^A so that it is recognized as a local label.
6682 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6684 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6685 i/o opcodes - inb, inw, outb and outw. string manipulation with
6686 att syntax - scmp, slod, smov, ssca, ssto.
6688 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6689 to just after .file .
6691 In obj_crawl_symbol_chain() where it tries to put the external
6692 symbols apart, with the condition:
6693 (!S_IS_DEFINED(symbolP) &&
6694 !S_IS_DEBUG(symbolP) &&
6695 !SF_GET_STATICS(symbolP))
6696 it was moving too many symbols out. So I switch it back to the
6698 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6700 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6701 so that we don't use the F_RELFLG which make the linker complain
6702 that somebody has stripped the relocation info.
6704 Also, the AIX ld program require that the relocation table
6705 is sorted by r_vaddr like the standard ATT assembler does.
6707 [he also changed the sizeof(struct ...)'s into the coff
6708 style FOOSZ macros. I'm not sure this is right, but I can't
6709 remember why. xoxorich.]
6711 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6713 * Makefile.in, configure.in, doc: use the doc. Build it, install
6716 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6718 * read.c: white space and comments only.
6720 * configure.in: use the new atof-ns32.c for ns32k.
6722 * write.c: comment change only.
6724 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6725 aren't yet integrated.
6727 * tc-i860.[hc]: blew off the dust. Something must still be done
6728 about conflicting relocation types.
6730 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6733 * tc-i960.c, tc-sparc.c: white space and comments only.
6735 * tc-a29k.h: delete duplicate macro definition.
6737 * new file atof-ns32k.c copied from hack's last unreleased gas.
6739 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6741 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6744 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6745 ChangeLog's prior to this are sketchy at best. I have logs.
6746 They just aren't ChangeLogs.
6750 version-control: never
