3 * listing.c (list_symbol_table): Print "NO DEFINED SYMBOLS" and
4 "NO UNDEFINED SYMBOLS" if there aren't any, instead of displaying
5 the header with an empty list.
7 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
8 also before setting STYP_NOLOAD for .bss section.
10 * config/tc-m68k.c (flag_reg_prefix_optional): New variable.

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

32 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
33 R_DIR16, and R_DIR32 relocs.

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

67 * listing.c (list_symbol_table): Don't print register symbols as
70 * config/obj-coff.c (obj_symbol_new_hook): Don't need to strip
71 underscores, since symbol_new will already have done it.
72 * config/obj-coffbfd.c (obj_symbol_new_hook): Ditto.
74 * as.c (main): If tc_init_after_args is defined, invoke it after
75 all arguments have been processed.
77 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
78 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext
79 section instead of .text. Call create_target_segments.

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

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

180 (macro): Likewise. For M_LA_AB permit a difference expression
181 when generating embedded PIC code between an arbitrary symbol and
182 a symbol in the .text section.

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

248 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
249 don't spew remainder of input file in error message.
250 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
251 message with reloc type and try to process remainder of file.
253 * doc/Makefile.in (install-info-as, install-info-gasp): New
254 targets, now explicitly checking $(srcdir) for info files.
255 (install-info): Depend on both of them; do nothing more.

263 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
264 flag rather than signedp field. Only permit extended range if
265 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
266 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
268 * config/tc-ppc.c (ppc_size): New static variable.
269 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
270 (md_begin): If an instruction has a size specific flag set, only
271 add it if we are assembling that size.
273 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
275 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
276 cross section PC relative relocs right for COFF and ELF.
278 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
280 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

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

303 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
304 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
306 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
307 branch with an instruction that uses $at, in case the branch is
309 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
310 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
311 to make it pcrel_offset.
312 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
313 reloc->address; another gruesome hack to get gas reloc handling to
316 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
318 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

322 (md_assemble): Call it.
323 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
325 (lituse_pending): New variable. Set by anything that generates a
326 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
327 tested by code that might want to emit a LITUSE reloc.
328 (emit_unaligned_io): New function. Currently calls md_assemble,
329 but it should eventually be converted to generate the insn itself
330 and call emit_insn directly.
331 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
332 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
333 emit_bis_r): Likewise.

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

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

380 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
382 * Makefile.in (config-stamp): If `defs' is defined, emit a
383 preprocessor directive to create a macro named by this value into
384 config.new; don't explicitly go for BFD_ASSEMBLER.
385 * configure.in: Define `defs', not `BFDDEF'. Set it to
386 MANY_SEGMENTS for any obj-coffbfd target.
387 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
388 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
390 (LOCAL_LOADLIBES): Deleted.
391 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
392 * config/m88kcoff.mt (TDEFINES): Ditto.
393 * config/ebmon29k.mt: Deleted.
394 * config/h8300hds.mt: Deleted.
395 * config/ic960coff.mt: Deleted.
396 * config/sparc.mt: Deleted.
397 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
398 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
399 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

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

448 (in_signed_range): New function.
450 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
451 (sparc_ip, label "immediate"): Reject constants for pcrel
452 instructions only if the relocation type indicates a "call"
453 instruction and the offset is within range of a "jmpl %g0". If
454 it's not in range, use the absolute section symbol plus an offset.
455 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
457 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
459 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
462 * configure.in: Eliminated all targets using obj-coff but not
463 defining BFD_ASSEMBLER; I think all such targets that are
464 supported will be matched by real CPU-OS combinations earlier in
466 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
467 some comments about the dpx2 configuration, but left it disabled,

2281 an example of marker relocations.
2282 * write.c (write_relocs): Instead of assuming size of a relocation
2283 is 4 bytes, pick up the size from relocation itself.

2311 BFD_RELOC_MIPS_GPREL. Added new case a.
2312 (set_at, load_register, macro): Changed calls to macro_build to
2313 pass new argument for i, j and o cases.
2314 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
2315 special handling when generating SVR4 PIC code.

2649 default is to assume production environment, and reject configs
2650 still being worked on. Mark Elf configurations (except sparc and
2651 i386) as developmental. Deleted cases matching some generic names
2652 in favor of more specific names. (E.g., when we get Alpha

2669 through inclusion of tc-hppa.h. Delete all forward declarations
2670 for functions only used within tc-hppa.c, likewise for structures,
2671 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2672 conditional code in a few small places.
2674 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

2677 conditional code -- try to group conditional code together
2678 into a few places. Make all functions and variables which
2679 are only used within tc-hppa.c static. PARAMize all functions.
2680 Add comments to functions. Delete unused functions, variables,
2681 #defines, etc. Delete unused members within structures. Delete
2682 ldil;ble hacks -- it is believed they were installed to work
2683 around old gas bugs. Avoid using mixed case for local
2684 functions, variables, and structures. Fix formatting problems
2685 not found by GNU-indent. Add FIXME notices for things which
2686 should be worked on the near future. Delete lots of old
2687 useless (1.36 PA-SOM) code.

2760 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2762 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2763 ELF, since the ELF object format does not have these type of
2764 relocations. Change the abort into as as_bad and return
2765 BFD_RELOC_NONE to silence compiler warnings.
2766 (md_assemble): Keep track of the instruction size. Allow white
2767 space between the $ and the constant for compatibility with older
2768 gases and other assemblers.
2769 (i386_operand): Skip spaces between $ and expression.

3764 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
3765 are also magic, and have special default flag settings.
3766 (obj_elf_frob_symbol): Since the return value from this function
3767 isn't used, don't bother calling obj_elf_write_symbol_p, since it
3768 doesn't accomplish anything else.

3780 undefined_section for the return value.
3782 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3783 pseudo-op with a poc_handler field of NULL, ignore it and treat it
3784 as an instruction instead.

3788 * config/tc-h8500.c (md_begin): Use a local variable when

3802 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3803 *-*-solaris case, and move to before *-sysv* case that wants to
3804 set obj_format to coff.

3830 * Extensive changes to permit symbols to contain any expression
3831 type and to delay the computation of the expression until the
3832 value is actually needed. This permits setting symbols to values
3833 calculated based on object code size. Expressions were changed to
3834 no longer be in a section, to stop the overloading of segment and
3835 expression type that previously occurred.
3837 * as.c (big_section, pass1_section, diff_section, absent_section):
3839 (expr_section): Added (used for dummy symbols which hold

3923 (previous_section, previous_subsection): New vars.
3924 (obj_elf_section): Save current place in case DWARF code wants us
3925 to pop back to it. Handle unquoted section name as well as quoted
3926 section name. Don't crash on invalid strings.
3927 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3930 * config/obj-elf.h: Don't include struc-symbol.h.

5153 process relocs if there aren't any relocs to process. Avoids
5154 malloc/free bug on SCO too.

5202 dropping a space immediately following an identifier.
5203 * expr.c, write.c: Rewrote assert expressions to not use multiple
5204 lines; I don't think that can be done portably.
5205 * config/tc-mips.c (macro): Use $AT if target register is zero in
5206 load instruction, which it can be for a floating point load.
5208 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5280 prototypes for all static functions. Moved existing minimal
5281 debugging format support info #ifndef OBJ_ECOFF blocks.

5330 * make-gas.com: Find obstack.obj if it's not in the current
5332 * read.c (s_ignore): Don't declare is_end_of_line. It's
5333 redundant, and triggers a VMS gcc compiler bug.
5335 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5336 current segment as an argument. (Ignored in all cases but VMS.)
5337 All callers and definitions changed.

5633 * config/tc-sparc.c (architecture_requested, warn_on_bump,
5634 md_relax_table): Use default zero initialization.
5635 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5636 latter, instead of selecting with preprocessor conditionals.
5638 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5640 * configure.in: recognise all sparclite variants
5642 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5644 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
5645 accidentally changed to use subseg_change where it should have
5648 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5650 * expr.c (operand): If character other than comma or newline is a
5651 logical end-of-line character, use the newline case.
5652 From Eric Youngdale:
5653 (operand): Set X_add_number field for floating-point numbers.
5654 (operand): Treat zero byte as end-of-operand.
5656 * configure.in (per-target): Look for with_bfd_assembler option.
5657 For now, only accept "no", until the merge is done.
5659 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5660 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5661 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5662 * read.c: Finish conversion to S_* macros in the VMS only
5663 parts of the program. Add "const" modifier to hex_value.
5664 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5666 * expr.c: Add "const" modifier to hex_value.
5667 * symbols.c: Finish conversion to S_* macros in the VMS only
5668 parts of the program. Add "const" modifier to
5669 md_[long,short]_jump_size. Remove declaration of const_flag
5670 (which will be declared in obj-vms.h).
5671 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5672 Fix arguments to VMS_write_object_file.
5673 * config-gas.com: New file. Script for VMS systems to set up the
5674 configuration to build gas for VMS, and create config.status.
5675 * make-gas.com: Redone to work with new scheme.
5676 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5678 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5679 will swap bytes if needed on a big endian system. Use throughout
5681 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5682 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5683 types of malformed stabs. Change parsing algorithm so that we are
5684 more certain of having all of the information that we need on hand.
5685 * obj-vms.c (final_forward_reference): New function, used to help
5686 resolve the data types of as many struct elements as possible
5687 when some part of the struct is not fully defined by the compiler.
5688 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5690 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5691 as symbols as well in the object file. Look for external functions
5692 that start with "__vt.", and turn them into variables, since the
5693 g++ compiler is incapable of doing this.
5694 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5696 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5697 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5698 have the name of the source file yet.
5699 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5701 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5703 * read.c (s_data): Always use "data_section", since it'll map to
5704 SEG_DATA or SEG_E1 if needed.
5705 (s_lcomm): Likewise with bss_section.
5706 (s_fill): Use memset, not bzero.
5708 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
5710 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

5724 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5725 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5729 (section_alignment): Declare only if not BFD_ASSEMBLER.
5730 (big_section, reg_section, pass1_section, diff_section,
5731 absent_section, text_section, data_section, bss_section): If
5732 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5733 mapping to segT enum values.
5734 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5735 if these are used or defined, if BFD_ASSEMBLER.
5736 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5737 subseg_new split into two functions.
5738 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5740 * as.h (volatile): Don't define if already defined.
5741 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5743 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5744 declare with format attribute for -Wformat checking.
5746 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5748 * app.c, config/tc-*.c: Don't include read.h, since it is already
5751 * These are based on patches from Minh Tran-le
5752 <mtranle@paris.intellicorp.com>.
5753 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5754 obj_format coffbfd and gas_target i386coff for target.
5755 (i[34]86-*-isc*): New host (uses sysv).
5756 * config/i386aix.mt: Removed (no longer used).
5757 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5759 (LDFLAGS): Added, defined as -shlib.
5760 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5761 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5762 (DOT_LABEL_PREFIX): Define.
5763 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5764 name rather than L0\001.
5765 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5767 * symbols.c, symbols.h (local_bss_counter): Removed.
5768 * write.c (write_object_file): bss no longer uses
5769 local_bss_counter. Pass correct data and bss size to
5770 VMS_write_object_file.

5776 (size_section): Restored sanity check.
5777 (do_relocs_for): Base section address on s_paddr rather than
5778 computing it. Adjust a29k R_IHIHALF special case to account for
5779 section paddr (used to require paddr to be zero). If there are no
5780 reclos, set s_relptr to 0. Set relocation size in object_headers.
5781 (fill_section): Always set s_vaddr here, removing
5782 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5783 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5784 Set STYP_INFO for .comment.
5785 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5786 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5788 H_{SET,GET}_* macros.
5789 (do_linenos_for): Set lineno size in object_headers.
5790 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5791 set s_vaddr here. If string_byte_count remains 4, set it back to
5792 0, and only write strings out if there are some. Call
5793 fill_section before do_relocs_for and do_linenos_for.
5794 (obj_coff_section): Handle optional quoted second argument giving
5795 section characteristics.
5796 (obj_coff_bss): Added to handle .bss.
5797 (obj_coff_ident): Added to handle .ident (puts string in .comment

5800 (fixup_mdeps): Change to segment. Call frag_wane after
5802 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5803 adjustment (already happened only for common symbols, but this is
5805 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

5817 (do_scrub_next_char): For \", return " not '.
5818 (symbol_chars): Now const.
5820 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5821 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5823 * config/obj-coff.h: Don't use #elif.
5825 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5826 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5828 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5852 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5853 using ZERO_BASED_SEGMENTS.
5854 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5855 never set segment address for SEG_E2 (.bss) and don't write out
5856 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5857 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5858 definitions, and don't merge tags with non-tags. Check for .bf
5859 rather than just checking whether the second character is b and
5860 the third character is f.
5861 (obj_coff_val): gcc can generate values which we don't handle
5862 correctly; discard information for now, since it only affects the
5863 debugging information.

5865 (yank_symbols): Don't merge labels.
5866 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

6107 fix i960+non-bfd coff bit rot.
6108 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
6109 support for C source listings. (obj_coff_endef): look in the right
6110 part of the symbol for the symbol name
6112 * tc-m68k.c (get_num): make it work for all segments, not just the
6115 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
6117 * configure.in: recognize i386-*-bsd emulation.

6126 * tc-z8k.c: lots of bug fixes
6128 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
6130 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
6131 #elif, since it is not supported by old compilers.
6132 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
6133 couple of expressions in tc-m68k.c.
6135 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6137 * read.c (cons): If NO_RELOC is defined, use it.
6139 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
6141 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
6143 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
6144 local labels to start with a .) and set REGISTER_PREFIX to %.
6145 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

6163 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
6164 sections starting from zero, rather than making them consecutive.
6165 This makes subsequent reloc calculations easier, esp if the object
6166 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
6167 allocate lcomm in .data rather than in .bss. It seems that some
6168 tools can't cope with a non-zero sized bss before linkage.
6170 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6172 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

6191 * Makefile.in (install): if $(tooldir) exists, install as in
6194 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
6196 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
6197 .word is < -32768 or > 32767. The -J flag causes the error to be
6198 ignored. This is to catch over-sized switches generated by gcc on
6199 systems which don't support the broken .word hack.
6200 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
6201 write.c (fixup_segment): check for signed .word overflow if
6202 WARN_SIGNED_OVERFLOW_WORD.

6221 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6223 * input-scrub.c (input_scrub_push): call input_file_begin, not
6225 messages.c (as_perror): print ": " between the passed in error and
6226 the strerror, like perror does.
6228 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

6231 From Steve Chamberlain:
6232 Makefile.in: Handle m68*-*-coff*.
6233 read.c, read.h: add mult argument to s_space
6235 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6236 Motorola and MIT syntax; gas can now assemble either type of
6238 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6244 (write_object_file) call fixup_mdeps
6245 (fixup_segment) set fx_subsy to 0.
6246 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6248 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6251 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6253 * Makefile.in (LIBS): Include opcode library.

6278 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6280 * config/tc-m68k.c (init_table): Now const. Always include 68851
6281 data, so that "bc" is available to 68040 cache instructions.
6282 Added "tt0", "tt1", and 68ec030 variants.
6283 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6284 (enum _register): Added TT0, TT1.
6285 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6286 line number correctly in "internal error" messages. Don't print
6287 architecture-mismatch message for operand errors.
6289 From Colin Smith (colin@wrs.com):
6290 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6291 than install_operand.

6312 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6313 has already been formatted (but may still contain %-characters).
6316 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6318 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6319 written with indirection on the last two operands, which can be
6320 either data or address registers. Added a new operand type 'r'
6321 which accepts either register type. Added '(' to notend stuff in
6322 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6594 * Makefile.in: pass down MAKEINFO explicitly on info.
6596 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
6598 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6600 * flonum-const.c: renamed flonum-konst.c to stop dos name
6603 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6605 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6606 tc-m68k.h to te-sun3.h.
6608 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6610 * configure.in: vxworks68 gets te-sun3.h.
6612 * expr.c: remove limitation that local_labels_dollar or
6613 local_labels_fb must be < 10.
6615 * symbols.c: remove local_labels_dollar, replace with a function
6616 interface for a sparse array. All users adjusted.
6618 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6620 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6622 * doc/Makefile.in: commented out line for building as-all.texinfo.
6625 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6627 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6629 * Makefile.in: added check target.
6631 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6633 * Makefile.in: added tooldir and program_prefix.
6635 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6637 * write.{c,h} (fix_new): Make these declarations consistent.
6639 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6641 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6644 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6646 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6648 * expr.c (operand): if can't work out what sort of operand it is,
6649 then look through FLT_CHARS for a hint.
6651 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6653 * Makefile.in, configure.in: removed traces of namesubdir,
6654 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6655 copyrights to '92, changed some from Cygnus to FSF.
6657 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6658 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6659 copyrights to '92, changed some from Cygnus to FSF.
6661 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6663 * expr.c: If an expression is single comma, then return with
6664 SEG_ABSENT rather than an error - since the sparc front end does
6665 really strange things with things like fbge,a
6667 * as.h: include bfd.h if using many sections
6668 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6669 local labels didn't work.
6670 * listing.c (list_symbol_table): don't core dump when there's no
6672 * write.c, write.h: call fix_new with the right number of args on
6674 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6677 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6679 * app.c: MRI compatibility - allow single quote to start a string.
6680 * as.c: fix typo recently introduced.
6681 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6682 * expr.c: Much rewriting, to accomodate MRI syntax for
6683 expressions. Also easier to read now.
6684 * listing.c: Put back defuns
6685 * read.c: modified to accept MRI syntax, put back listing pseudo
6686 ops so that an assembler built with NO_LISTING ignores list ops
6688 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6689 machine is a SPARC or a 29K.
6690 * config/obj-aout.c: added s_sect pseudo op
6691 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6692 fill in the timestamp.
6693 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6694 anymore, define all the relocs which the tc-<x> bit will use so we
6695 can translate from them to the coff types.
6696 * config/tc-a29k.c: reloc_type isn't ane enum any more
6697 * config/tc-m68k.c: Added NO_RELOC definition.
6699 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6701 * Makefile.in: put header files before C source for TAGS; remove
6702 references to non-existent syscalls.h.
6704 * read.c, write.c subsegs.c: back out the .bss changes.
6706 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6708 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6712 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6714 * symbols.c (local_label_name): symbols now start with ^A.
6716 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6717 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6718 generate these sections. .align: will use NOP_OPCODE or 0
6719 for padding. This is just for being nice to the
6722 * expr.c (operand): changed to generate local label "\001L0"
6723 starting with a ^A so that it is recognized as a local label.
6725 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6727 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6728 i/o opcodes - inb, inw, outb and outw. string manipulation with
6729 att syntax - scmp, slod, smov, ssca, ssto.
6731 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6732 to just after .file .
6734 In obj_crawl_symbol_chain() where it tries to put the external
6735 symbols apart, with the condition:
6736 (!S_IS_DEFINED(symbolP) &&
6737 !S_IS_DEBUG(symbolP) &&
6738 !SF_GET_STATICS(symbolP))
6739 it was moving too many symbols out. So I switch it back to the
6741 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6743 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6744 so that we don't use the F_RELFLG which make the linker complain
6745 that somebody has stripped the relocation info.
6747 Also, the AIX ld program require that the relocation table
6748 is sorted by r_vaddr like the standard ATT assembler does.
6750 [he also changed the sizeof(struct ...)'s into the coff
6751 style FOOSZ macros. I'm not sure this is right, but I can't
6752 remember why. xoxorich.]
6754 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6756 * Makefile.in, configure.in, doc: use the doc. Build it, install
6759 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6761 * read.c: white space and comments only.
6763 * configure.in: use the new atof-ns32.c for ns32k.
6765 * write.c: comment change only.
6767 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6768 aren't yet integrated.
6770 * tc-i860.[hc]: blew off the dust. Something must still be done
6771 about conflicting relocation types.
6773 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6776 * tc-i960.c, tc-sparc.c: white space and comments only.
6778 * tc-a29k.h: delete duplicate macro definition.
6780 * new file atof-ns32k.c copied from hack's last unreleased gas.
6782 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6784 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6787 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6788 ChangeLog's prior to this are sketchy at best. I have logs.
6789 They just aren't ChangeLogs.
6793 version-control: never
