8 * config/obj-ecoff.c (ecoff_frob_file): Use bfd_ecoff_set_gp_value
9 and bfd_ecoff_set_regmasks to set the GP value and the register
10 masks, rather than using the now obsolete fake .reginfo section.
12 Fri Apr 22 15:17:06 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
14 * listing.c (list_symbol_table): Don't print register symbols as
17 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
18 underscores, since symbol_new will already have done it.
19 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
21 * as.c (main): If tc_init_after_args is defined, invoke it after
22 all arguments have been processed.
24 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
25 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
26 section instead of .text. Call create_target_segments.
27 * read.c (demand_copy_string): No longer static.

31 * config/tc-mips.c (append_insn): Permit branches to be switched
32 with the preceding instruction even if .set nobopt has been seen.
33 .set nobopt actually controls whether to bring up an instruction
34 from the branch target, which gas does not currently support.

75 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
76 defaults for defined, private, and spnum fields for the
77 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
78 not reset the segment if just updating a space.
79 (pa_spaces_begin): Set BFD section flags for all built-in
82 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

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

125 argument, the reloc type.
126 (load_register): Pass reloc type to macro_build for 'u'.
127 (macro): Likewise. For M_LA_AB permit a difference expression
128 when generating embedded PIC code between an arbitrary symbol and
129 a symbol in the .text section.
130 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
131 BFD_RELOC_PCREL_LO16 to be emitted.
132 (md_apply_fix): Check that most relocs are not PC relative.
133 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.
134 (tc_gen_reloc): Change #error to as_fatal. Handle
135 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.
137 Tue Apr 12 18:25:13 1994 Stan Shebs (shebs@andros.cygnus.com)
139 * subsegs.c (subsegs_begin): Call memset with args in the correct
141 (subseg_get): Clear newly allocated seginfo, set its pointer slots
142 to NULL instead of 0.
144 Mon Apr 11 09:00:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
146 * config/tc-hppa.c (pa_procend): Handle case where label was
147 defined after the .proc directive.
149 * config/tc-hppa.c (pa_procend): Give an error if we encounter a

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

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

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

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

305 * config/tc-mips.c (enum mips_pic_level): New enum.
306 (mips_pic): Change from int to enum mips_pic_level. Change all
307 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
308 (load_address): Handle EMBEDDED_PIC.
309 (macro): Handle EMBEDDED_PIC in all PIC cases.
310 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
311 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
312 -non_shared to use NO_PIC (this is how the Irix 5 assembler
313 works). Do not permit -G with SVR4_PIC.
314 (s_abicalls): Warn if -G was used, and force -G 0.
315 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
316 anything but a.out, not just for ELF. For ECOFF, don't generate a
317 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
319 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
321 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
323 * config/tc-hppa.c (create_new_space): Use ints, not chars as
324 parameters to avoid losing when compiling with HP CC.

327 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
329 * Makefile.in (config-stamp): If `defs' is defined, emit a
330 preprocessor directive to create a macro named by this value into
331 config.new; don't explicitly go for BFD_ASSEMBLER.
332 * configure.in: Define `defs', not `BFDDEF'. Set it to
333 MANY_SEGMENTS for any obj-coffbfd target.
334 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
335 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
337 (LOCAL_LOADLIBES): Deleted.
338 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
339 * config/m88kcoff.mt (TDEFINES): Ditto.
340 * config/ebmon29k.mt: Deleted.
341 * config/h8300hds.mt: Deleted.
342 * config/ic960coff.mt: Deleted.
343 * config/sparc.mt: Deleted.
344 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
345 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
346 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
347 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.

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

2260 pass new argument for i, j and o cases.
2261 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2482 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2483 the table, require that the one without bit 0x1000000 set come
2484 first. Require further that it be case 'b' or 'P'. The a29k

2596 default is to assume production environment, and reject configs
2597 still being worked on. Mark Elf configurations (except sparc and
2598 i386) as developmental. Deleted cases matching some generic names
2599 in favor of more specific names. (E.g., when we get Alpha

2616 through inclusion of tc-hppa.h. Delete all forward declarations
2617 for functions only used within tc-hppa.c, likewise for structures,
2618 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2619 conditional code in a few small places.
2621 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2622 structures, global variables, forward declarations together.

2624 conditional code -- try to group conditional code together
2625 into a few places. Make all functions and variables which
2626 are only used within tc-hppa.c static. PARAMize all functions.
2627 Add comments to functions. Delete unused functions, variables,
2628 #defines, etc. Delete unused members within structures. Delete
2629 ldil;ble hacks -- it is believed they were installed to work
2630 around old gas bugs. Avoid using mixed case for local
2631 functions, variables, and structures. Fix formatting problems
2632 not found by GNU-indent. Add FIXME notices for things which
2633 should be worked on the near future. Delete lots of old
2634 useless (1.36 PA-SOM) code.

2663 a multiple of the section alignment rather than always a
2666 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2707 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2709 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2710 ELF, since the ELF object format does not have these type of
2711 relocations. Change the abort into as as_bad and return
2712 BFD_RELOC_NONE to silence compiler warnings.
2713 (md_assemble): Keep track of the instruction size. Allow white
2714 space between the $ and the constant for compatibility with older
2715 gases and other assemblers.
2716 (i386_operand): Skip spaces between $ and expression.

3747 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3748 case to set obj_format=elf. Must go before i386-*-sysv* case that
3749 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3750 *-*-solaris case, and move to before *-sysv* case that wants to
3751 set obj_format to coff.

3777 * Extensive changes to permit symbols to contain any expression
3778 type and to delay the computation of the expression until the
3779 value is actually needed. This permits setting symbols to values
3780 calculated based on object code size. Expressions were changed to
3781 no longer be in a section, to stop the overloading of segment and
3782 expression type that previously occurred.
3784 * as.c (big_section, pass1_section, diff_section, absent_section):
3786 (expr_section): Added (used for dummy symbols which hold

3870 (previous_section, previous_subsection): New vars.
3871 (obj_elf_section): Save current place in case DWARF code wants us
3872 to pop back to it. Handle unquoted section name as well as quoted
3873 section name. Don't crash on invalid strings.
3874 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3877 * config/obj-elf.h: Don't include struc-symbol.h.

3917 use new macro tc_frob_label.
3918 * config/tc-hppa.h (tc_frob_label): Define.
3920 * config/tc-mips.c: Many changes to support simple assembler

3986 sy_resolved and sy_resolving single bit fields.
3987 * symbols.c (symbol_new): Don't initialize sy_forward field.

5076 source directory, if that's not the current directory.
5078 * configure.in (per-host): Accept MIPS host with BSD version

5104 avoid some redefinition complaints on some systems.
5105 (const, volatile): Don't need these conditionally defined if we
5106 use CONST and VOLATILE from ansidecl.h.
5107 (seg_name): Use CONST, not const.

5115 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

5122 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5124 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5125 srcdir, might be in objdir.

5144 * Makefile.in (targ-cpu.o): Depend on config.h.
5146 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
5148 * app.c (do_scrub_next_char): Added new state, 9, to avoid
5149 dropping a space immediately following an identifier.

5151 lines; I don't think that can be done portably.

5638 as symbols as well in the object file. Look for external functions
5639 that start with "__vt.", and turn them into variables, since the
5640 g++ compiler is incapable of doing this.
5641 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5643 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5644 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5645 have the name of the source file yet.
5646 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5648 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5650 * read.c (s_data): Always use "data_section", since it'll map to
5651 SEG_DATA or SEG_E1 if needed.
5652 (s_lcomm): Likewise with bss_section.
5653 (s_fill): Use memset, not bzero.
5655 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5671 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5672 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5676 (section_alignment): Declare only if not BFD_ASSEMBLER.
5677 (big_section, reg_section, pass1_section, diff_section,
5678 absent_section, text_section, data_section, bss_section): If
5679 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5680 mapping to segT enum values.
5681 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5682 if these are used or defined, if BFD_ASSEMBLER.
5683 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5684 subseg_new split into two functions.
5685 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5687 * as.h (volatile): Don't define if already defined.
5688 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5690 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5691 declare with format attribute for -Wformat checking.
5693 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5695 * app.c, config/tc-*.c: Don't include read.h, since it is already
5698 * These are based on patches from Minh Tran-le
5699 <mtranle@paris.intellicorp.com>.
5700 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5701 obj_format coffbfd and gas_target i386coff for target.
5702 (i[34]86-*-isc*): New host (uses sysv).
5703 * config/i386aix.mt: Removed (no longer used).
5704 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5706 (LDFLAGS): Added, defined as -shlib.
5707 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5708 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5709 (DOT_LABEL_PREFIX): Define.
5710 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5711 name rather than L0\001.
5712 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5714 * symbols.c, symbols.h (local_bss_counter): Removed.
5715 * write.c (write_object_file): bss no longer uses
5716 local_bss_counter. Pass correct data and bss size to
5717 VMS_write_object_file.

5723 (size_section): Restored sanity check.
5724 (do_relocs_for): Base section address on s_paddr rather than
5725 computing it. Adjust a29k R_IHIHALF special case to account for
5726 section paddr (used to require paddr to be zero). If there are no
5727 reclos, set s_relptr to 0. Set relocation size in object_headers.
5728 (fill_section): Always set s_vaddr here, removing
5729 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5730 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5731 Set STYP_INFO for .comment.
5732 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5733 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
5734 (crawl_symbols): Handle 8 character section name correctly. Use
5735 H_{SET,GET}_* macros.
5736 (do_linenos_for): Set lineno size in object_headers.
5737 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5738 set s_vaddr here. If string_byte_count remains 4, set it back to
5739 0, and only write strings out if there are some. Call
5740 fill_section before do_relocs_for and do_linenos_for.
5741 (obj_coff_section): Handle optional quoted second argument giving
5742 section characteristics.
5743 (obj_coff_bss): Added to handle .bss.
5744 (obj_coff_ident): Added to handle .ident (puts string in .comment

5747 (fixup_mdeps): Change to segment. Call frag_wane after
5749 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5750 adjustment (already happened only for common symbols, but this is
5752 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

5764 (do_scrub_next_char): For \", return " not '.
5765 (symbol_chars): Now const.
5767 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5768 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5770 * config/obj-coff.h: Don't use #elif.
5772 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5773 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5800 using ZERO_BASED_SEGMENTS.
5801 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5802 never set segment address for SEG_E2 (.bss) and don't write out
5803 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5804 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5805 definitions, and don't merge tags with non-tags. Check for .bf
5806 rather than just checking whether the second character is b and
5807 the third character is f.
5808 (obj_coff_val): gcc can generate values which we don't handle
5809 correctly; discard information for now, since it only affects the
5810 debugging information.
5811 (tag_find_or_name): Don't insert tags in the symbol table.
5812 (yank_symbols): Don't merge labels.
5813 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6078 #elif, since it is not supported by old compilers.
6079 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6080 couple of expressions in tc-m68k.c.

6111 sections starting from zero, rather than making them consecutive.
6112 This makes subsequent reloc calculations easier, esp if the object
6113 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6114 allocate lcomm in .data rather than in .bss. It seems that some
6115 tools can't cope with a non-zero sized bss before linkage.
6117 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6119 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6120 throughout. That enum no longer means what we thought it meant.

6141 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6143 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6144 .word is < -32768 or > 32767. The -J flag causes the error to be
6145 ignored. This is to catch over-sized switches generated by gcc on
6146 systems which don't support the broken .word hack.
6147 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6148 write.c (fixup_segment): check for signed .word overflow if
6149 WARN_SIGNED_OVERFLOW_WORD.

6178 From Steve Chamberlain:
6179 Makefile.in: Handle m68*-*-coff*.
6180 read.c, read.h: add mult argument to s_space
6182 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6183 Motorola and MIT syntax; gas can now assemble either type of

6195 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6198 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6200 * Makefile.in (LIBS): Include opcode library.

6227 * config/tc-m68k.c (init_table): Now const. Always include 68851
6228 data, so that "bc" is available to 68040 cache instructions.
6229 Added "tt0", "tt1", and 68ec030 variants.
6230 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6231 (enum _register): Added TT0, TT1.
6232 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6233 line number correctly in "internal error" messages. Don't print
6234 architecture-mismatch message for operand errors.

6259 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6260 has already been formatted (but may still contain %-characters).
6263 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6265 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6266 written with indirection on the last two operands, which can be
6267 either data or address registers. Added a new operand type 'r'
6268 which accepts either register type. Added '(' to notend stuff in
6269 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6612 really strange things with things like fbge,a
6614 * as.h: include bfd.h if using many sections
6615 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6616 local labels didn't work.
6617 * listing.c (list_symbol_table): don't core dump when there's no
6619 * write.c, write.h: call fix_new with the right number of args on
6621 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make

6626 * app.c: MRI compatibility - allow single quote to start a string.
6627 * as.c: fix typo recently introduced.
6628 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6629 * expr.c: Much rewriting, to accomodate MRI syntax for
6630 expressions. Also easier to read now.
6631 * listing.c: Put back defuns
6632 * read.c: modified to accept MRI syntax, put back listing pseudo
6633 ops so that an assembler built with NO_LISTING ignores list ops
6635 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6636 machine is a SPARC or a 29K.
6637 * config/obj-aout.c: added s_sect pseudo op
6638 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6639 fill in the timestamp.
6640 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6641 anymore, define all the relocs which the tc-<x> bit will use so we
6642 can translate from them to the coff types.
6643 * config/tc-a29k.c: reloc_type isn't ane enum any more
6644 * config/tc-m68k.c: Added NO_RELOC definition.
6646 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6648 * Makefile.in: put header files before C source for TAGS; remove
6649 references to non-existent syscalls.h.
6651 * read.c, write.c subsegs.c: back out the .bss changes.
6653 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6655 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6659 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6661 * symbols.c (local_label_name): symbols now start with ^A.
6663 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6664 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6665 generate these sections. .align: will use NOP_OPCODE or 0
6666 for padding. This is just for being nice to the
6669 * expr.c (operand): changed to generate local label "\001L0"
6670 starting with a ^A so that it is recognized as a local label.
6672 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6674 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6675 i/o opcodes - inb, inw, outb and outw. string manipulation with
6676 att syntax - scmp, slod, smov, ssca, ssto.
6678 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6679 to just after .file .
6681 In obj_crawl_symbol_chain() where it tries to put the external
6682 symbols apart, with the condition:
6683 (!S_IS_DEFINED(symbolP) &&
6684 !S_IS_DEBUG(symbolP) &&
6685 !SF_GET_STATICS(symbolP))
6686 it was moving too many symbols out. So I switch it back to the
6688 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6690 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6691 so that we don't use the F_RELFLG which make the linker complain
6692 that somebody has stripped the relocation info.
6694 Also, the AIX ld program require that the relocation table
6695 is sorted by r_vaddr like the standard ATT assembler does.
6697 [he also changed the sizeof(struct ...)'s into the coff
6698 style FOOSZ macros. I'm not sure this is right, but I can't
6699 remember why. xoxorich.]
6701 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6703 * Makefile.in, configure.in, doc: use the doc. Build it, install
6706 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6708 * read.c: white space and comments only.
6710 * configure.in: use the new atof-ns32.c for ns32k.
6712 * write.c: comment change only.
6714 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6715 aren't yet integrated.
6717 * tc-i860.[hc]: blew off the dust. Something must still be done
6718 about conflicting relocation types.
6720 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6723 * tc-i960.c, tc-sparc.c: white space and comments only.
6725 * tc-a29k.h: delete duplicate macro definition.
6727 * new file atof-ns32k.c copied from hack's last unreleased gas.
6729 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6731 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6734 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6735 ChangeLog's prior to this are sketchy at best. I have logs.
6736 They just aren't ChangeLogs.
6740 version-control: never
