17 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
18 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
19 the header with an empty list.
21 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
22 also before setting STYP_NOLOAD for .bss section.
24 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.
25 Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or

41 * config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
42 Define as macros instead of enumerators, since the Apollo compiler
43 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum

50 [TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
51 do include the optional header for Apollo target.
52 (COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
54 * config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
55 can be used within a label name.
57 * config/tc-m68k.h (m68k_init_after_args): Declare.

81 * listing.c (list_symbol_table): Don't print register symbols as
84 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
85 underscores, since symbol_new will already have done it.
86 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
88 * as.c (main): If tc_init_after_args is defined, invoke it after
89 all arguments have been processed.
91 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
92 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
93 section instead of .text. Call create_target_segments.
94 * read.c (demand_copy_string): No longer static.

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

119 multiple of alignment power specified in bfd target vector.
121 * gasp.c: Include ctype.h.

166 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
168 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
170 * vmsconf.sh: In generated file, get ".obj" suffix right, build
171 source files from other directories into objects in the current
172 directory, and specify PSECT attributes explicitly to linker.
173 Also added missing label.
174 * Makefile.in (stamp-mk.com): Reference new variable
175 VMS_OTHER_OBJS for list of non-local object files, instead of

192 argument, the reloc type.
193 (load_register): Pass reloc type to macro_build for 'u'.
194 (macro): Likewise. For M_LA_AB permit a difference expression
195 when generating embedded PIC code between an arbitrary symbol and
196 a symbol in the .text section.

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

262 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
263 don't spew remainder of input file in error message.
264 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
265 message with reloc type and try to process remainder of file.
267 * doc/Makefile.in (install-info-as, install-info-gasp): New
268 targets, now explicitly checking $(srcdir) for info files.
269 (install-info): Depend on both of them; do nothing more.
271 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
273 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
275 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
277 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
278 flag rather than signedp field. Only permit extended range if
279 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
280 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
282 * config/tc-ppc.c (ppc_size): New static variable.
283 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
284 (md_begin): If an instruction has a size specific flag set, only
285 add it if we are assembling that size.
287 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
289 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
290 cross section PC relative relocs right for COFF and ELF.
292 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
294 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

305 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
306 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
307 and -many (all architectures).

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

336 (md_assemble): Call it.
337 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
339 (lituse_pending): New variable. Set by anything that generates a
340 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
341 tested by code that might want to emit a LITUSE reloc.
342 (emit_unaligned_io): New function. Currently calls md_assemble,
343 but it should eventually be converted to generate the insn itself
344 and call emit_insn directly.
345 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
346 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
347 emit_bis_r): Likewise.

354 the value can't be resolved.
356 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
358 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
359 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
360 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
362 (mips_force_relocation): New function.

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

394 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
396 * Makefile.in (config-stamp): If `defs' is defined, emit a
397 preprocessor directive to create a macro named by this value into
398 config.new; don't explicitly go for BFD_ASSEMBLER.
399 * configure.in: Define `defs', not `BFDDEF'. Set it to
400 MANY_SEGMENTS for any obj-coffbfd target.
401 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
402 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
404 (LOCAL_LOADLIBES): Deleted.
405 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
406 * config/m88kcoff.mt (TDEFINES): Ditto.

432 bfd_set_symtab is called.
433 (dump_section_relocs): Note whether a symbol is a section symbol
435 (adjust_reloc_syms): For now, always supply an absolute symbol for
436 fixups without symbols but not yet `done'. Use section_symbol to
437 get the symbol, instead of going directly for abs_symbol.
438 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
439 reloc is not a section symbol and is not in the symbol table.
440 (set_symtab): New function, broken out from write_object_file.
441 Counts symbol table instead of relying on an earlier count.
442 (write_object_file): Call set_symtab, but do it after potentially
443 invoking the *_frob_file macros. Don't bother counting symbols.
444 Call symbol_remove, instead of expanding it in place. Moved the
445 conditionalized `object_file_size' declaration down to
446 conditionalized block where it's used. When using the absolute
447 symbol for a fixup without a symbol, set sy_used_in_reloc.
448 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
449 the correct symbol for the absolute section.
451 * subsegs.c (section_symbol): Use symbol_new instead of
452 symbol_make, since we may want it to go into the symbol table.
453 Make the new symbol have internal linkage. If
454 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
455 symbol with the newly created GAS symbol.
456 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
457 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

462 (in_signed_range): New function.
464 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
465 (sparc_ip, label "immediate"): Reject constants for pcrel
466 instructions only if the relocation type indicates a "call"
467 instruction and the offset is within range of a "jmpl %g0". If
468 it's not in range, use the absolute section symbol plus an offset.

2325 BFD_RELOC_MIPS_GPREL. Added new case a.
2326 (set_at, load_register, macro): Changed calls to macro_build to
2327 pass new argument for i, j and o cases.
2328 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
2329 special handling when generating SVR4 PIC code.

2549 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2550 the table, require that the one without bit 0x1000000 set come

2662 for keeping or rejecting configurations still under development;
2663 default is to assume production environment, and reject configs
2664 still being worked on. Mark Elf configurations (except sparc and
2665 i386) as developmental. Deleted cases matching some generic names
2666 in favor of more specific names. (E.g., when we get Alpha

2683 through inclusion of tc-hppa.h. Delete all forward declarations
2684 for functions only used within tc-hppa.c, likewise for structures,
2685 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2686 conditional code in a few small places.
2688 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2689 structures, global variables, forward declarations together.

2691 conditional code -- try to group conditional code together
2692 into a few places. Make all functions and variables which
2693 are only used within tc-hppa.c static. PARAMize all functions.
2694 Add comments to functions. Delete unused functions, variables,
2695 #defines, etc. Delete unused members within structures. Delete
2696 ldil;ble hacks -- it is believed they were installed to work
2697 around old gas bugs. Avoid using mixed case for local
2698 functions, variables, and structures. Fix formatting problems
2699 not found by GNU-indent. Add FIXME notices for things which
2700 should be worked on the near future. Delete lots of old
2701 useless (1.36 PA-SOM) code.

2774 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2776 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2777 ELF, since the ELF object format does not have these type of
2778 relocations. Change the abort into as as_bad and return
2779 BFD_RELOC_NONE to silence compiler warnings.
2780 (md_assemble): Keep track of the instruction size. Allow white
2781 space between the $ and the constant for compatibility with older
2782 gases and other assemblers.
2783 (i386_operand): Skip spaces between $ and expression.

3732 * config/ho-sunos.h: remove some old function decls that conflict
3733 w/ ANSI, and which weren't needed anyway
3735 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3737 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

3779 are also magic, and have special default flag settings.
3780 (obj_elf_frob_symbol): Since the return value from this function
3781 isn't used, don't bother calling obj_elf_write_symbol_p, since it
3782 doesn't accomplish anything else.

3794 undefined_section for the return value.
3796 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3797 pseudo-op with a poc_handler field of NULL, ignore it and treat it
3798 as an instruction instead.

3814 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3815 case to set obj_format=elf. Must go before i386-*-sysv* case that
3816 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3817 *-*-solaris case, and move to before *-sysv* case that wants to

3844 * Extensive changes to permit symbols to contain any expression
3845 type and to delay the computation of the expression until the
3846 value is actually needed. This permits setting symbols to values
3847 calculated based on object code size. Expressions were changed to
3848 no longer be in a section, to stop the overloading of segment and
3849 expression type that previously occurred.
3851 * as.c (big_section, pass1_section, diff_section, absent_section):
3853 (expr_section): Added (used for dummy symbols which hold

3937 (previous_section, previous_subsection): New vars.
3938 (obj_elf_section): Save current place in case DWARF code wants us
3939 to pop back to it. Handle unquoted section name as well as quoted
3940 section name. Don't crash on invalid strings.
3941 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3944 * config/obj-elf.h: Don't include struc-symbol.h.

4053 sy_resolved and sy_resolving single bit fields.
4054 * symbols.c (symbol_new): Don't initialize sy_forward field.

5167 process relocs if there aren't any relocs to process. Avoids
5168 malloc/free bug on SCO too.

5216 dropping a space immediately following an identifier.
5217 * expr.c, write.c: Rewrote assert expressions to not use multiple
5218 lines; I don't think that can be done portably.
5219 * config/tc-mips.c (macro): Use $AT if target register is zero in
5220 load instruction, which it can be for a floating point load.
5222 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5294 prototypes for all static functions. Moved existing minimal
5295 debugging format support info #ifndef OBJ_ECOFF blocks.

5346 * read.c (s_ignore): Don't declare is_end_of_line. It's
5347 redundant, and triggers a VMS gcc compiler bug.
5349 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5350 current segment as an argument. (Ignored in all cases but VMS.)
5351 All callers and definitions changed.

5643 offset field is set.
5645 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5647 * config/tc-sparc.c (architecture_requested, warn_on_bump,
5648 md_relax_table): Use default zero initialization.
5649 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5650 latter, instead of selecting with preprocessor conditionals.
5652 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5654 * configure.in: recognise all sparclite variants
5656 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5658 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
5659 accidentally changed to use subseg_change where it should have
5662 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5664 * expr.c (operand): If character other than comma or newline is a
5665 logical end-of-line character, use the newline case.
5666 From Eric Youngdale:
5667 (operand): Set X_add_number field for floating-point numbers.
5668 (operand): Treat zero byte as end-of-operand.
5670 * configure.in (per-target): Look for with_bfd_assembler option.
5671 For now, only accept "no", until the merge is done.
5673 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5674 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5675 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5676 * read.c: Finish conversion to S_* macros in the VMS only
5677 parts of the program. Add "const" modifier to hex_value.
5678 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5680 * expr.c: Add "const" modifier to hex_value.
5681 * symbols.c: Finish conversion to S_* macros in the VMS only
5682 parts of the program. Add "const" modifier to
5683 md_[long,short]_jump_size. Remove declaration of const_flag
5684 (which will be declared in obj-vms.h).
5685 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5686 Fix arguments to VMS_write_object_file.
5687 * config-gas.com: New file. Script for VMS systems to set up the
5688 configuration to build gas for VMS, and create config.status.
5689 * make-gas.com: Redone to work with new scheme.
5690 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5692 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5693 will swap bytes if needed on a big endian system. Use throughout
5695 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5696 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5697 types of malformed stabs. Change parsing algorithm so that we are
5698 more certain of having all of the information that we need on hand.
5699 * obj-vms.c (final_forward_reference): New function, used to help
5700 resolve the data types of as many struct elements as possible
5701 when some part of the struct is not fully defined by the compiler.
5702 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5704 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5705 as symbols as well in the object file. Look for external functions
5706 that start with "__vt.", and turn them into variables, since the
5707 g++ compiler is incapable of doing this.
5708 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5710 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5711 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5712 have the name of the source file yet.
5713 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5715 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5717 * read.c (s_data): Always use "data_section", since it'll map to
5718 SEG_DATA or SEG_E1 if needed.
5719 (s_lcomm): Likewise with bss_section.
5720 (s_fill): Use memset, not bzero.
5722 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
5724 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

5738 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5739 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5743 (section_alignment): Declare only if not BFD_ASSEMBLER.
5744 (big_section, reg_section, pass1_section, diff_section,
5745 absent_section, text_section, data_section, bss_section): If
5746 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5747 mapping to segT enum values.
5748 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5749 if these are used or defined, if BFD_ASSEMBLER.
5750 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5751 subseg_new split into two functions.
5752 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5754 * as.h (volatile): Don't define if already defined.
5755 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5757 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5758 declare with format attribute for -Wformat checking.
5760 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5762 * app.c, config/tc-*.c: Don't include read.h, since it is already
5765 * These are based on patches from Minh Tran-le
5766 <mtranle@paris.intellicorp.com>.
5767 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5768 obj_format coffbfd and gas_target i386coff for target.
5769 (i[34]86-*-isc*): New host (uses sysv).
5770 * config/i386aix.mt: Removed (no longer used).
5771 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5773 (LDFLAGS): Added, defined as -shlib.
5774 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5775 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5776 (DOT_LABEL_PREFIX): Define.
5777 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5778 name rather than L0\001.
5779 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5781 * symbols.c, symbols.h (local_bss_counter): Removed.
5782 * write.c (write_object_file): bss no longer uses
5783 local_bss_counter. Pass correct data and bss size to
5784 VMS_write_object_file.

5790 (size_section): Restored sanity check.
5791 (do_relocs_for): Base section address on s_paddr rather than
5792 computing it. Adjust a29k R_IHIHALF special case to account for
5793 section paddr (used to require paddr to be zero). If there are no
5794 reclos, set s_relptr to 0. Set relocation size in object_headers.
5795 (fill_section): Always set s_vaddr here, removing
5796 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5797 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5798 Set STYP_INFO for .comment.
5799 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5800 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5802 H_{SET,GET}_* macros.
5803 (do_linenos_for): Set lineno size in object_headers.
5804 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5805 set s_vaddr here. If string_byte_count remains 4, set it back to
5806 0, and only write strings out if there are some. Call
5807 fill_section before do_relocs_for and do_linenos_for.
5808 (obj_coff_section): Handle optional quoted second argument giving
5809 section characteristics.
5810 (obj_coff_bss): Added to handle .bss.
5811 (obj_coff_ident): Added to handle .ident (puts string in .comment

5814 (fixup_mdeps): Change to segment. Call frag_wane after
5816 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5817 adjustment (already happened only for common symbols, but this is
5819 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
5820 * config/tc-i386.c (s_bss): Don't use if I386COFF.

5831 (do_scrub_next_char): For \", return " not '.
5832 (symbol_chars): Now const.
5834 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5835 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5837 * config/obj-coff.h: Don't use #elif.
5839 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5840 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5842 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5866 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5867 using ZERO_BASED_SEGMENTS.
5868 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5869 never set segment address for SEG_E2 (.bss) and don't write out
5870 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5871 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5872 definitions, and don't merge tags with non-tags. Check for .bf
5873 rather than just checking whether the second character is b and
5874 the third character is f.
5875 (obj_coff_val): gcc can generate values which we don't handle
5876 correctly; discard information for now, since it only affects the
5877 debugging information.
5878 (tag_find_or_name): Don't insert tags in the symbol table.
5879 (yank_symbols): Don't merge labels.
5880 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6121 fix i960+non-bfd coff bit rot.
6122 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
6123 support for C source listings. (obj_coff_endef): look in the right
6124 part of the symbol for the symbol name
6126 * tc-m68k.c (get_num): make it work for all segments, not just the
6129 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

6140 * tc-z8k.c: lots of bug fixes
6142 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6144 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6145 #elif, since it is not supported by old compilers.
6146 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6147 couple of expressions in tc-m68k.c.
6149 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6151 * read.c (cons): If NO_RELOC is defined, use it.
6153 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6155 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6157 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6158 local labels to start with a .) and set REGISTER_PREFIX to %.
6159 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

6177 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6178 sections starting from zero, rather than making them consecutive.
6179 This makes subsequent reloc calculations easier, esp if the object
6180 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6181 allocate lcomm in .data rather than in .bss. It seems that some
6182 tools can't cope with a non-zero sized bss before linkage.
6184 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6186 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6208 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6210 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6211 .word is < -32768 or > 32767. The -J flag causes the error to be
6212 ignored. This is to catch over-sized switches generated by gcc on
6213 systems which don't support the broken .word hack.
6214 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6215 write.c (fixup_segment): check for signed .word overflow if
6216 WARN_SIGNED_OVERFLOW_WORD.
6218 * write.c (fixup_segment): fixed missing parens in expression
6219 checking for byte or word overflow.

6235 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6237 * input-scrub.c (input_scrub_push): call input_file_begin, not
6239 messages.c (as_perror): print ": " between the passed in error and
6240 the strerror, like perror does.
6242 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

6245 From Steve Chamberlain:
6246 Makefile.in: Handle m68*-*-coff*.
6247 read.c, read.h: add mult argument to s_space
6249 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6250 Motorola and MIT syntax; gas can now assemble either type of
6252 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6259 (fixup_segment) set fx_subsy to 0.
6260 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6262 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6265 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6267 * Makefile.in (LIBS): Include opcode library.

6292 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6294 * config/tc-m68k.c (init_table): Now const. Always include 68851
6295 data, so that "bc" is available to 68040 cache instructions.
6296 Added "tt0", "tt1", and 68ec030 variants.
6297 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6298 (enum _register): Added TT0, TT1.
6299 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6300 line number correctly in "internal error" messages. Don't print
6301 architecture-mismatch message for operand errors.
6303 From Colin Smith (colin@wrs.com):
6304 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

6326 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6327 has already been formatted (but may still contain %-characters).
6330 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6332 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6333 written with indirection on the last two operands, which can be
6334 either data or address registers. Added a new operand type 'r'
6335 which accepts either register type. Added '(' to notend stuff in
6336 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6600 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
6602 * symbols.c (fb_label_init): fix sizeof to memset.
6604 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
6606 * Makefile.in: install the man page.
6608 * Makefile.in: pass down MAKEINFO explicitly on info.
6610 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
6612 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6614 * flonum-const.c: renamed flonum-konst.c to stop dos name
6617 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6619 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6620 tc-m68k.h to te-sun3.h.
6622 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6624 * configure.in: vxworks68 gets te-sun3.h.
6626 * expr.c: remove limitation that local_labels_dollar or
6627 local_labels_fb must be < 10.
6629 * symbols.c: remove local_labels_dollar, replace with a function
6630 interface for a sparse array. All users adjusted.
6632 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6634 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6636 * doc/Makefile.in: commented out line for building as-all.texinfo.
6639 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6641 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6643 * Makefile.in: added check target.
6645 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6647 * Makefile.in: added tooldir and program_prefix.
6649 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6651 * write.{c,h} (fix_new): Make these declarations consistent.
6653 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6655 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6658 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6660 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6662 * expr.c (operand): if can't work out what sort of operand it is,
6663 then look through FLT_CHARS for a hint.
6665 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6667 * Makefile.in, configure.in: removed traces of namesubdir,
6668 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6669 copyrights to '92, changed some from Cygnus to FSF.
6671 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6672 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6673 copyrights to '92, changed some from Cygnus to FSF.
6675 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6677 * expr.c: If an expression is single comma, then return with
6678 SEG_ABSENT rather than an error - since the sparc front end does
6679 really strange things with things like fbge,a
6681 * as.h: include bfd.h if using many sections
6682 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6683 local labels didn't work.
6684 * listing.c (list_symbol_table): don't core dump when there's no
6686 * write.c, write.h: call fix_new with the right number of args on
6688 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6691 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6693 * app.c: MRI compatibility - allow single quote to start a string.
6694 * as.c: fix typo recently introduced.
6695 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6696 * expr.c: Much rewriting, to accomodate MRI syntax for
6697 expressions. Also easier to read now.
6698 * listing.c: Put back defuns
6699 * read.c: modified to accept MRI syntax, put back listing pseudo
6700 ops so that an assembler built with NO_LISTING ignores list ops
6702 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6703 machine is a SPARC or a 29K.
6704 * config/obj-aout.c: added s_sect pseudo op
6705 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6706 fill in the timestamp.
6707 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6708 anymore, define all the relocs which the tc-<x> bit will use so we
6709 can translate from them to the coff types.
6710 * config/tc-a29k.c: reloc_type isn't ane enum any more
6711 * config/tc-m68k.c: Added NO_RELOC definition.
6713 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6715 * Makefile.in: put header files before C source for TAGS; remove
6716 references to non-existent syscalls.h.
6718 * read.c, write.c subsegs.c: back out the .bss changes.
6720 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6722 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6726 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6728 * symbols.c (local_label_name): symbols now start with ^A.
6730 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6731 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6732 generate these sections. .align: will use NOP_OPCODE or 0
6733 for padding. This is just for being nice to the
6736 * expr.c (operand): changed to generate local label "\001L0"
6737 starting with a ^A so that it is recognized as a local label.
6739 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6741 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6742 i/o opcodes - inb, inw, outb and outw. string manipulation with
6743 att syntax - scmp, slod, smov, ssca, ssto.
6745 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6746 to just after .file .
6748 In obj_crawl_symbol_chain() where it tries to put the external
6749 symbols apart, with the condition:
6750 (!S_IS_DEFINED(symbolP) &&
6751 !S_IS_DEBUG(symbolP) &&
6752 !SF_GET_STATICS(symbolP))
6753 it was moving too many symbols out. So I switch it back to the
6755 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6757 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6758 so that we don't use the F_RELFLG which make the linker complain
6759 that somebody has stripped the relocation info.
6761 Also, the AIX ld program require that the relocation table
6762 is sorted by r_vaddr like the standard ATT assembler does.
6764 [he also changed the sizeof(struct ...)'s into the coff
6765 style FOOSZ macros. I'm not sure this is right, but I can't
6766 remember why. xoxorich.]
6768 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6770 * Makefile.in, configure.in, doc: use the doc. Build it, install
6773 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6775 * read.c: white space and comments only.
6777 * configure.in: use the new atof-ns32.c for ns32k.
6779 * write.c: comment change only.
6781 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6782 aren't yet integrated.
6784 * tc-i860.[hc]: blew off the dust. Something must still be done
6785 about conflicting relocation types.
6787 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6790 * tc-i960.c, tc-sparc.c: white space and comments only.
6792 * tc-a29k.h: delete duplicate macro definition.
6794 * new file atof-ns32k.c copied from hack's last unreleased gas.
6796 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6798 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6801 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6802 ChangeLog's prior to this are sketchy at best. I have logs.
6803 They just aren't ChangeLogs.
6807 version-control: never
