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

42 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only
43 when BFD_ASSEMBLER is not defined, and all conditionals relating
44 to such code. No such targets remain.

79 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
80 defaults for defined, private, and spnum fields for the
81 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
82 not reset the segment if just updating a space.
83 (pa_spaces_begin): Set BFD section flags for all built-in
86 Fri Apr 15 10:51:51 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

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

127 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
128 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
129 argument, the reloc type.
130 (load_register): Pass reloc type to macro_build for 'u'.
131 (macro): Likewise. For M_LA_AB permit a difference expression
132 when generating embedded PIC code between an arbitrary symbol and
133 a symbol in the .text section.
134 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
135 BFD_RELOC_PCREL_LO16 to be emitted.
136 (md_apply_fix): Check that most relocs are not PC relative.
137 Handle BFD_RELOC_PCREL_HI16_S and BFD_RELOC_PCREL_LO16.
138 (tc_gen_reloc): Change #error to as_fatal. Handle
139 BFD_RELOC_PCREL_LO16 and BFD_RELOC_PCREL_HI16_S.

143 * subsegs.c (subsegs_begin): Call memset with args in the correct
145 (subseg_get): Clear newly allocated seginfo, set its pointer slots
146 to NULL instead of 0.
148 Mon Apr 11 09:00:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
150 * config/tc-hppa.c (pa_procend): Handle case where label was
151 defined after the .proc directive.
153 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
154 procend for a procedure without a name.

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

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

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

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

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

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

369 bfd_set_symtab is called.
370 (dump_section_relocs): Note whether a symbol is a section symbol
372 (adjust_reloc_syms): For now, always supply an absolute symbol for
373 fixups without symbols but not yet `done'. Use section_symbol to
374 get the symbol, instead of going directly for abs_symbol.
375 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
376 reloc is not a section symbol and is not in the symbol table.
377 (set_symtab): New function, broken out from write_object_file.
378 Counts symbol table instead of relying on an earlier count.
379 (write_object_file): Call set_symtab, but do it after potentially
380 invoking the *_frob_file macros. Don't bother counting symbols.
381 Call symbol_remove, instead of expanding it in place. Moved the
382 conditionalized `object_file_size' declaration down to
383 conditionalized block where it's used. When using the absolute
384 symbol for a fixup without a symbol, set sy_used_in_reloc.
385 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
386 the correct symbol for the absolute section.
388 * subsegs.c (section_symbol): Use symbol_new instead of
389 symbol_make, since we may want it to go into the symbol table.
390 Make the new symbol have internal linkage. If
391 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
392 symbol with the newly created GAS symbol.
393 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
394 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

398 * config/tc-sparc.c: Include subsegs.h.
399 (in_signed_range): New function.
401 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
402 (sparc_ip, label "immediate"): Reject constants for pcrel
403 instructions only if the relocation type indicates a "call"
404 instruction and the offset is within range of a "jmpl %g0". If
405 it's not in range, use the absolute section symbol plus an offset.
406 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
408 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
410 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
413 * configure.in: Eliminated all targets using obj-coff but not
414 defining BFD_ASSEMBLER; I think all such targets that are
415 supported will be matched by real CPU-OS combinations earlier in
417 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
418 some comments about the dpx2 configuration, but left it disabled,
419 since it couldn't be reached before.
420 (target a29k-amd-ebmonold): Deleted.
422 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
424 * config/tc-hppa.c (pa_import): Correctly handle importing of an
425 already defined symbol.

429 * config/tc-mips.c (mips_ip): Only accept overly large values for
430 the 'j' operand if there are no further alternatives for this
433 * config/obj-coffbfd.c (adjust_stab_section): Initialize
434 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
435 is not SEG_UNKNOWN rather than checking whether it is >= 0.
437 * config/tc-mips.c (mips_align): Take new argument, label, and use
438 it instead of global insn_label.
439 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
440 call to mips_emit_delay and pass it to mips_align.
442 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
444 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
446 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
447 argument to a .callinfo directive. Don't loop forever on errors.
449 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
450 use pre-defined registers as arguments.
452 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
454 * write.c (write_object_file): Check both S_IS_LOCAL and
455 S_IS_EXTERNAL when deciding whether to discard a symbol.
457 * config-gas.com: Scan Makefile.in, not version.c, for current
458 version number. Delete all versions of temp files when finished
459 with them. Create config.h.
461 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
462 values to reduce number of lookups with S_GET_VALUE. Skip debug
463 symbols to avoid "a really nasty bug". (From Holger Teutsch,
464 holger@botbso.rhein-main.de.)
465 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
466 field. (Also from Holger Teutsch.) Watch for a would-be register
467 mask that spans frags.
469 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
470 this_base, not line_base. (Patch from Andreas Arens,
471 ari@obelix.av.rwth-aachen.de.)
473 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
474 look local if they're exported or undefined. Used to be done for

2212 descriptor information to the BFD symbol.
2213 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

2232 an example of marker relocations.
2233 * write.c (write_relocs): Instead of assuming size of a relocation
2234 is 4 bytes, pick up the size from relocation itself.

2264 pass new argument for i, j and o cases.
2265 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2486 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2487 the table, require that the one without bit 0x1000000 set come

2599 for keeping or rejecting configurations still under development;
2600 default is to assume production environment, and reject configs
2601 still being worked on. Mark Elf configurations (except sparc and
2602 i386) as developmental. Deleted cases matching some generic names
2603 in favor of more specific names. (E.g., when we get Alpha

2620 through inclusion of tc-hppa.h. Delete all forward declarations
2621 for functions only used within tc-hppa.c, likewise for structures,
2622 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2623 conditional code in a few small places.
2625 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2626 structures, global variables, forward declarations together.

2628 conditional code -- try to group conditional code together
2629 into a few places. Make all functions and variables which
2630 are only used within tc-hppa.c static. PARAMize all functions.
2631 Add comments to functions. Delete unused functions, variables,
2632 #defines, etc. Delete unused members within structures. Delete
2633 ldil;ble hacks -- it is believed they were installed to work
2634 around old gas bugs. Avoid using mixed case for local
2635 functions, variables, and structures. Fix formatting problems
2636 not found by GNU-indent. Add FIXME notices for things which
2637 should be worked on the near future. Delete lots of old
2638 useless (1.36 PA-SOM) code.

2667 a multiple of the section alignment rather than always a
2670 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2711 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2713 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2714 ELF, since the ELF object format does not have these type of
2715 relocations. Change the abort into as as_bad and return
2716 BFD_RELOC_NONE to silence compiler warnings.
2717 (md_assemble): Keep track of the instruction size. Allow white
2718 space between the $ and the constant for compatibility with older
2719 gases and other assemblers.
2720 (i386_operand): Skip spaces between $ and expression.

3753 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3754 *-*-solaris case, and move to before *-sysv* case that wants to

3781 * Extensive changes to permit symbols to contain any expression
3782 type and to delay the computation of the expression until the
3783 value is actually needed. This permits setting symbols to values
3784 calculated based on object code size. Expressions were changed to
3785 no longer be in a section, to stop the overloading of segment and
3786 expression type that previously occurred.
3788 * as.c (big_section, pass1_section, diff_section, absent_section):
3790 (expr_section): Added (used for dummy symbols which hold

3874 (previous_section, previous_subsection): New vars.
3875 (obj_elf_section): Save current place in case DWARF code wants us
3876 to pop back to it. Handle unquoted section name as well as quoted
3877 section name. Don't crash on invalid strings.
3878 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3881 * config/obj-elf.h: Don't include struc-symbol.h.

3966 (omagic): Removed unused variable.
3968 * Preliminary support for m88k-coff.

3990 sy_resolved and sy_resolving single bit fields.
3991 * symbols.c (symbol_new): Don't initialize sy_forward field.

5108 avoid some redefinition complaints on some systems.

5126 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
5128 * Makefile.in: add dvi target; as-$(config).texinfo might live in
5129 srcdir, might be in objdir.

5153 dropping a space immediately following an identifier.

5641 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5642 as symbols as well in the object file. Look for external functions
5643 that start with "__vt.", and turn them into variables, since the
5644 g++ compiler is incapable of doing this.
5645 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5647 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5648 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5649 have the name of the source file yet.
5650 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5652 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5654 * read.c (s_data): Always use "data_section", since it'll map to
5655 SEG_DATA or SEG_E1 if needed.
5656 (s_lcomm): Likewise with bss_section.
5657 (s_fill): Use memset, not bzero.
5659 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5675 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5676 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5680 (section_alignment): Declare only if not BFD_ASSEMBLER.
5681 (big_section, reg_section, pass1_section, diff_section,
5682 absent_section, text_section, data_section, bss_section): If
5683 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5684 mapping to segT enum values.
5685 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5686 if these are used or defined, if BFD_ASSEMBLER.
5687 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5688 subseg_new split into two functions.
5689 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5691 * as.h (volatile): Don't define if already defined.
5692 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5694 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5695 declare with format attribute for -Wformat checking.
5697 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5699 * app.c, config/tc-*.c: Don't include read.h, since it is already
5702 * These are based on patches from Minh Tran-le
5703 <mtranle@paris.intellicorp.com>.
5704 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5705 obj_format coffbfd and gas_target i386coff for target.
5706 (i[34]86-*-isc*): New host (uses sysv).
5707 * config/i386aix.mt: Removed (no longer used).
5708 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5710 (LDFLAGS): Added, defined as -shlib.
5711 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5712 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5713 (DOT_LABEL_PREFIX): Define.
5714 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5715 name rather than L0\001.
5716 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5718 * symbols.c, symbols.h (local_bss_counter): Removed.
5719 * write.c (write_object_file): bss no longer uses

5727 (size_section): Restored sanity check.
5728 (do_relocs_for): Base section address on s_paddr rather than
5729 computing it. Adjust a29k R_IHIHALF special case to account for
5730 section paddr (used to require paddr to be zero). If there are no
5731 reclos, set s_relptr to 0. Set relocation size in object_headers.
5732 (fill_section): Always set s_vaddr here, removing
5733 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5734 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5735 Set STYP_INFO for .comment.
5736 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5737 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5739 H_{SET,GET}_* macros.
5740 (do_linenos_for): Set lineno size in object_headers.
5741 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5742 set s_vaddr here. If string_byte_count remains 4, set it back to
5743 0, and only write strings out if there are some. Call
5744 fill_section before do_relocs_for and do_linenos_for.
5745 (obj_coff_section): Handle optional quoted second argument giving
5746 section characteristics.
5747 (obj_coff_bss): Added to handle .bss.
5748 (obj_coff_ident): Added to handle .ident (puts string in .comment

5751 (fixup_mdeps): Change to segment. Call frag_wane after
5753 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5754 adjustment (already happened only for common symbols, but this is
5756 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

5768 (do_scrub_next_char): For \", return " not '.
5769 (symbol_chars): Now const.
5771 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5772 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5774 * config/obj-coff.h: Don't use #elif.
5776 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5777 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5804 using ZERO_BASED_SEGMENTS.
5805 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5806 never set segment address for SEG_E2 (.bss) and don't write out
5807 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5808 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5809 definitions, and don't merge tags with non-tags. Check for .bf
5810 rather than just checking whether the second character is b and
5811 the third character is f.
5812 (obj_coff_val): gcc can generate values which we don't handle
5813 correctly; discard information for now, since it only affects the
5814 debugging information.
5815 (tag_find_or_name): Don't insert tags in the symbol table.
5816 (yank_symbols): Don't merge labels.
5817 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6115 sections starting from zero, rather than making them consecutive.
6116 This makes subsequent reloc calculations easier, esp if the object
6117 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6118 allocate lcomm in .data rather than in .bss. It seems that some
6119 tools can't cope with a non-zero sized bss before linkage.
6121 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6123 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
6124 throughout. That enum no longer means what we thought it meant.

6145 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6147 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6148 .word is < -32768 or > 32767. The -J flag causes the error to be
6149 ignored. This is to catch over-sized switches generated by gcc on
6150 systems which don't support the broken .word hack.
6151 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6152 write.c (fixup_segment): check for signed .word overflow if
6153 WARN_SIGNED_OVERFLOW_WORD.

6182 From Steve Chamberlain:
6183 Makefile.in: Handle m68*-*-coff*.
6184 read.c, read.h: add mult argument to s_space
6186 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6187 Motorola and MIT syntax; gas can now assemble either type of
6189 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6197 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6199 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6202 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6204 * Makefile.in (LIBS): Include opcode library.

6229 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6231 * config/tc-m68k.c (init_table): Now const. Always include 68851
6232 data, so that "bc" is available to 68040 cache instructions.
6233 Added "tt0", "tt1", and 68ec030 variants.
6234 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6235 (enum _register): Added TT0, TT1.
6236 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6237 line number correctly in "internal error" messages. Don't print
6238 architecture-mismatch message for operand errors.
6240 From Colin Smith (colin@wrs.com):
6241 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

6263 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6264 has already been formatted (but may still contain %-characters).
6267 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6269 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6270 written with indirection on the last two operands, which can be
6271 either data or address registers. Added a new operand type 'r'
6272 which accepts either register type. Added '(' to notend stuff in
6273 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6614 * expr.c: If an expression is single comma, then return with
6615 SEG_ABSENT rather than an error - since the sparc front end does
6616 really strange things with things like fbge,a
6618 * as.h: include bfd.h if using many sections
6619 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6620 local labels didn't work.
6621 * listing.c (list_symbol_table): don't core dump when there's no
6623 * write.c, write.h: call fix_new with the right number of args on
6625 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6628 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6630 * app.c: MRI compatibility - allow single quote to start a string.
6631 * as.c: fix typo recently introduced.
6632 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6633 * expr.c: Much rewriting, to accomodate MRI syntax for
6634 expressions. Also easier to read now.
6635 * listing.c: Put back defuns
6636 * read.c: modified to accept MRI syntax, put back listing pseudo
6637 ops so that an assembler built with NO_LISTING ignores list ops
6639 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6640 machine is a SPARC or a 29K.
6641 * config/obj-aout.c: added s_sect pseudo op
6642 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6643 fill in the timestamp.
6644 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6645 anymore, define all the relocs which the tc-<x> bit will use so we
6646 can translate from them to the coff types.
6647 * config/tc-a29k.c: reloc_type isn't ane enum any more
6648 * config/tc-m68k.c: Added NO_RELOC definition.
6650 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6652 * Makefile.in: put header files before C source for TAGS; remove
6653 references to non-existent syscalls.h.
6655 * read.c, write.c subsegs.c: back out the .bss changes.
6657 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6659 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6663 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6665 * symbols.c (local_label_name): symbols now start with ^A.
6667 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6668 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6669 generate these sections. .align: will use NOP_OPCODE or 0
6670 for padding. This is just for being nice to the
6673 * expr.c (operand): changed to generate local label "\001L0"
6674 starting with a ^A so that it is recognized as a local label.
6676 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6678 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6679 i/o opcodes - inb, inw, outb and outw. string manipulation with
6680 att syntax - scmp, slod, smov, ssca, ssto.
6682 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6683 to just after .file .
6685 In obj_crawl_symbol_chain() where it tries to put the external
6686 symbols apart, with the condition:
6687 (!S_IS_DEFINED(symbolP) &&
6688 !S_IS_DEBUG(symbolP) &&
6689 !SF_GET_STATICS(symbolP))
6690 it was moving too many symbols out. So I switch it back to the
6692 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6694 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6695 so that we don't use the F_RELFLG which make the linker complain
6696 that somebody has stripped the relocation info.
6698 Also, the AIX ld program require that the relocation table
6699 is sorted by r_vaddr like the standard ATT assembler does.
6701 [he also changed the sizeof(struct ...)'s into the coff
6702 style FOOSZ macros. I'm not sure this is right, but I can't
6703 remember why. xoxorich.]
6705 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6707 * Makefile.in, configure.in, doc: use the doc. Build it, install
6710 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6712 * read.c: white space and comments only.
6714 * configure.in: use the new atof-ns32.c for ns32k.
6716 * write.c: comment change only.
6718 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6719 aren't yet integrated.
6721 * tc-i860.[hc]: blew off the dust. Something must still be done
6722 about conflicting relocation types.
6724 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6727 * tc-i960.c, tc-sparc.c: white space and comments only.
6729 * tc-a29k.h: delete duplicate macro definition.
6731 * new file atof-ns32k.c copied from hack's last unreleased gas.
6733 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6735 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6738 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6739 ChangeLog's prior to this are sketchy at best. I have logs.
6740 They just aren't ChangeLogs.
6744 version-control: never
