27 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
29 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
30 branch with an instruction that uses $at, in case the branch is
32 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
33 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
34 to make it pcrel_offset.
35 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
36 reloc->address; another gruesome hack to get gas reloc handling to
39 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
41 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
44 (emit_insn): New function.
45 (md_assemble): Call it.
46 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
48 (lituse_pending): New variable. Set by anything that generates a
49 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
50 tested by code that might want to emit a LITUSE reloc.
51 (emit_unaligned_io): New function. Currently calls md_assemble,
52 but it should eventually be converted to generate the insn itself
53 and call emit_insn directly.
54 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
55 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
56 emit_bis_r): Likewise.

67 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
68 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

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

103 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
105 * Makefile.in (config-stamp): If `defs' is defined, emit a
106 preprocessor directive to create a macro named by this value into
107 config.new; don't explicitly go for BFD_ASSEMBLER.
108 * configure.in: Define `defs', not `BFDDEF'. Set it to
109 MANY_SEGMENTS for any obj-coffbfd target.
110 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
111 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
113 (LOCAL_LOADLIBES): Deleted.
114 * config/m68kcoff.mt (TDEFINES): Don't define those macros.

141 bfd_set_symtab is called.
142 (dump_section_relocs): Note whether a symbol is a section symbol
144 (adjust_reloc_syms): For now, always supply an absolute symbol for
145 fixups without symbols but not yet `done'. Use section_symbol to
146 get the symbol, instead of going directly for abs_symbol.
147 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
148 reloc is not a section symbol and is not in the symbol table.
149 (set_symtab): New function, broken out from write_object_file.
150 Counts symbol table instead of relying on an earlier count.
151 (write_object_file): Call set_symtab, but do it after potentially
152 invoking the *_frob_file macros. Don't bother counting symbols.
153 Call symbol_remove, instead of expanding it in place. Moved the
154 conditionalized `object_file_size' declaration down to
155 conditionalized block where it's used. When using the absolute
156 symbol for a fixup without a symbol, set sy_used_in_reloc.
157 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
158 the correct symbol for the absolute section.
160 * subsegs.c (section_symbol): Use symbol_new instead of
161 symbol_make, since we may want it to go into the symbol table.
162 Make the new symbol have internal linkage. If
163 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
164 symbol with the newly created GAS symbol.
165 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
166 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

173 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
174 (sparc_ip, label "immediate"): Reject constants for pcrel
175 instructions only if the relocation type indicates a "call"
176 instruction and the offset is within range of a "jmpl %g0". If
177 it's not in range, use the absolute section symbol plus an offset.
178 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
180 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
182 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
185 * configure.in: Eliminated all targets using obj-coff but not
186 defining BFD_ASSEMBLER; I think all such targets that are
187 supported will be matched by real CPU-OS combinations earlier in
189 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
190 some comments about the dpx2 configuration, but left it disabled,
191 since it couldn't be reached before.
192 (target a29k-amd-ebmonold): Deleted.
194 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

202 the 'j' operand if there are no further alternatives for this
205 * config/obj-coffbfd.c (adjust_stab_section): Initialize
206 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
207 is not SEG_UNKNOWN rather than checking whether it is >= 0.
209 * config/tc-mips.c (mips_align): Take new argument, label, and use
210 it instead of global insn_label.
211 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
212 call to mips_emit_delay and pass it to mips_align.
214 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
216 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
218 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
219 argument to a .callinfo directive. Don't loop forever on errors.
221 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
222 use pre-defined registers as arguments.
224 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

227 S_IS_EXTERNAL when deciding whether to discard a symbol.
229 * config-gas.com: Scan Makefile.in, not version.c, for current
230 version number. Delete all versions of temp files when finished
231 with them. Create config.h.
233 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
234 values to reduce number of lookups with S_GET_VALUE. Skip debug

236 holger@botbso.rhein-main.de.)
237 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
238 field. (Also from Holger Teutsch.) Watch for a would-be register
239 mask that spans frags.
241 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
242 this_base, not line_base. (Patch from Andreas Arens,
243 ari@obelix.av.rwth-aachen.de.)
245 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
246 look local if they're exported or undefined. Used to be done for
249 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

253 (lex_type): Use it for `%'.
255 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2373 still being worked on. Mark Elf configurations (except sparc and
2374 i386) as developmental. Deleted cases matching some generic names
2375 in favor of more specific names. (E.g., when we get Alpha
2376 support, we'll still only support VMS for Vax.)
2378 * config/tc-sparc.h (md_end): New macro.
2379 * config/tc-sparc.c (md_end): Function deleted.
2380 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd
2381 version compiling. All sparc targets will use bfd now.

2386 * read.c (next_char_of_string): Limit octal character constants to
2389 * config/tc-hppa.h: Major cleanup. Use GNU-style comments. Warn
2390 against placing additional object-file dependent code here. Warn
2391 against contaminating all of GAS with the internals of tc-hppa.c
2392 through inclusion of tc-hppa.h. Delete all forward declarations
2393 for functions only used within tc-hppa.c, likewise for structures,
2394 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2395 conditional code in a few small places.
2397 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2398 structures, global variables, forward declarations together.
2399 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2400 conditional code -- try to group conditional code together
2401 into a few places. Make all functions and variables which
2402 are only used within tc-hppa.c static. PARAMize all functions.
2403 Add comments to functions. Delete unused functions, variables,
2404 #defines, etc. Delete unused members within structures. Delete
2405 ldil;ble hacks -- it is believed they were installed to work
2406 around old gas bugs. Avoid using mixed case for local
2407 functions, variables, and structures. Fix formatting problems
2408 not found by GNU-indent. Add FIXME notices for things which
2409 should be worked on the near future. Delete lots of old
2410 useless (1.36 PA-SOM) code.
2412 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
2413 field of the fixS structure. Needed to build unwind

2422 which do not involve function symbols.
2424 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
2425 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
2427 * config/tc-hppa.c: Likewise.
2429 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2430 of elf32_symbol_type.
2431 (pa_export_args): Likewise.
2432 (elf_hppa_final_processing): Likewise.
2433 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

2438 * config/tc-hppa.c: (md_section_align): Align all sections to
2439 a multiple of the section alignment rather than always a
2442 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2443 bits are zero (eg they specify no relocations), then do not even
2444 bother adding their entries to thesymextn section.

2483 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2485 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2486 ELF, since the ELF object format does not have these type of
2487 relocations. Change the abort into as as_bad and return
2488 BFD_RELOC_NONE to silence compiler warnings.
2489 (md_assemble): Keep track of the instruction size. Allow white
2490 space between the $ and the constant for compatibility with older
2491 gases and other assemblers.

4852 source directory, if that's not the current directory.
4854 * configure.in (per-host): Accept MIPS host with BSD version

4880 avoid some redefinition complaints on some systems.
4881 (const, volatile): Don't need these conditionally defined if we
4882 use CONST and VOLATILE from ansidecl.h.
4883 (seg_name): Use CONST, not const.
4885 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4887 * config/tc-mips.c: Reindented to GNU standards.

4891 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4892 (fixup_segment): Add a29k special case; the linker is not prepared
4893 to see a segment offset here.
4895 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4898 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4900 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4901 srcdir, might be in objdir.

4920 * Makefile.in (targ-cpu.o): Depend on config.h.
4922 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4924 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4925 dropping a space immediately following an identifier.
4926 * expr.c, write.c: Rewrote assert expressions to not use multiple
4927 lines; I don't think that can be done portably.
4928 * config/tc-mips.c (macro): Use $AT if target register is zero in
4929 load instruction, which it can be for a floating point load.
4931 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4952 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4954 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4955 to be on a single line.

5003 prototypes for all static functions. Moved existing minimal
5004 debugging format support info #ifndef OBJ_ECOFF blocks.

5053 * make-gas.com: Find obstack.obj if it's not in the current
5055 * read.c (s_ignore): Don't declare is_end_of_line. It's
5056 redundant, and triggers a VMS gcc compiler bug.
5058 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5059 current segment as an argument. (Ignored in all cases but VMS.)
5060 All callers and definitions changed.

5079 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5080 Call elf_xstabs for .stabs and .xstabs operators.

5357 md_relax_table): Use default zero initialization.
5358 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5359 latter, instead of selecting with preprocessor conditionals.
5361 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5363 * configure.in: recognise all sparclite variants

5373 * expr.c (operand): If character other than comma or newline is a
5374 logical end-of-line character, use the newline case.
5375 From Eric Youngdale:
5376 (operand): Set X_add_number field for floating-point numbers.
5377 (operand): Treat zero byte as end-of-operand.
5379 * configure.in (per-target): Look for with_bfd_assembler option.
5380 For now, only accept "no", until the merge is done.
5382 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5383 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5389 * expr.c: Add "const" modifier to hex_value.
5390 * symbols.c: Finish conversion to S_* macros in the VMS only
5391 parts of the program. Add "const" modifier to
5392 md_[long,short]_jump_size. Remove declaration of const_flag
5393 (which will be declared in obj-vms.h).
5394 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5395 Fix arguments to VMS_write_object_file.
5396 * config-gas.com: New file. Script for VMS systems to set up the
5397 configuration to build gas for VMS, and create config.status.
5398 * make-gas.com: Redone to work with new scheme.
5399 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5401 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

5404 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5405 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5406 types of malformed stabs. Change parsing algorithm so that we are
5407 more certain of having all of the information that we need on hand.
5408 * obj-vms.c (final_forward_reference): New function, used to help
5409 resolve the data types of as many struct elements as possible
5410 when some part of the struct is not fully defined by the compiler.

5413 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5414 as symbols as well in the object file. Look for external functions
5415 that start with "__vt.", and turn them into variables, since the
5416 g++ compiler is incapable of doing this.
5417 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5419 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5420 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5421 have the name of the source file yet.
5422 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5424 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5426 * read.c (s_data): Always use "data_section", since it'll map to
5427 SEG_DATA or SEG_E1 if needed.
5428 (s_lcomm): Likewise with bss_section.
5429 (s_fill): Use memset, not bzero.
5431 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5453 (big_section, reg_section, pass1_section, diff_section,
5454 absent_section, text_section, data_section, bss_section): If
5455 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5456 mapping to segT enum values.
5457 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5458 if these are used or defined, if BFD_ASSEMBLER.
5459 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5460 subseg_new split into two functions.
5461 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5463 * as.h (volatile): Don't define if already defined.
5464 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5466 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5467 declare with format attribute for -Wformat checking.
5469 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5471 * app.c, config/tc-*.c: Don't include read.h, since it is already
5474 * These are based on patches from Minh Tran-le
5475 <mtranle@paris.intellicorp.com>.
5476 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5477 obj_format coffbfd and gas_target i386coff for target.
5478 (i[34]86-*-isc*): New host (uses sysv).
5479 * config/i386aix.mt: Removed (no longer used).
5480 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5482 (LDFLAGS): Added, defined as -shlib.
5483 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5484 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5485 (DOT_LABEL_PREFIX): Define.
5486 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5487 name rather than L0\001.
5488 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5490 * symbols.c, symbols.h (local_bss_counter): Removed.
5491 * write.c (write_object_file): bss no longer uses

5499 (size_section): Restored sanity check.
5500 (do_relocs_for): Base section address on s_paddr rather than
5501 computing it. Adjust a29k R_IHIHALF special case to account for
5502 section paddr (used to require paddr to be zero). If there are no
5503 reclos, set s_relptr to 0. Set relocation size in object_headers.
5504 (fill_section): Always set s_vaddr here, removing
5505 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5506 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5507 Set STYP_INFO for .comment.
5508 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5509 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5511 H_{SET,GET}_* macros.
5512 (do_linenos_for): Set lineno size in object_headers.
5513 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5514 set s_vaddr here. If string_byte_count remains 4, set it back to
5515 0, and only write strings out if there are some. Call
5516 fill_section before do_relocs_for and do_linenos_for.
5517 (obj_coff_section): Handle optional quoted second argument giving
5518 section characteristics.
5519 (obj_coff_bss): Added to handle .bss.
5520 (obj_coff_ident): Added to handle .ident (puts string in .comment

5540 (do_scrub_next_char): For \", return " not '.
5541 (symbol_chars): Now const.
5543 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5544 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5546 * config/obj-coff.h: Don't use #elif.
5548 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5549 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5551 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5553 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5573 SEG_BSS, fill with NOP_OPCODE.
5574 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5575 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5576 using ZERO_BASED_SEGMENTS.
5577 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5578 never set segment address for SEG_E2 (.bss) and don't write out
5579 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5580 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5581 definitions, and don't merge tags with non-tags. Check for .bf
5582 rather than just checking whether the second character is b and
5583 the third character is f.
5584 (obj_coff_val): gcc can generate values which we don't handle
5585 correctly; discard information for now, since it only affects the
5586 debugging information.
5587 (tag_find_or_name): Don't insert tags in the symbol table.
5588 (yank_symbols): Don't merge labels.
5589 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5608 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
5609 power-of-two alignment for .align.
5611 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
5612 and leave everything else alone.
5614 Fri Dec 4 16:58:42 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

5735 could be doing emulation.
5737 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5740 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5769 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5771 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5772 constant will not fit in an immediate field.
5773 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5810 * Support for i386-sysv.
5811 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5851 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5853 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5854 #elif, since it is not supported by old compilers.
5855 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5856 couple of expressions in tc-m68k.c.
5858 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5860 * read.c (cons): If NO_RELOC is defined, use it.
5862 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5864 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5866 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5867 local labels to start with a .) and set REGISTER_PREFIX to %.
5868 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5870 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5884 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5886 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5887 sections starting from zero, rather than making them consecutive.
5888 This makes subsequent reloc calculations easier, esp if the object
5889 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5890 allocate lcomm in .data rather than in .bss. It seems that some
5891 tools can't cope with a non-zero sized bss before linkage.
5893 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5895 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5914 * Makefile.in (install): if $(tooldir) exists, install as in
5917 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5919 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5920 .word is < -32768 or > 32767. The -J flag causes the error to be
5921 ignored. This is to catch over-sized switches generated by gcc on
5922 systems which don't support the broken .word hack.
5923 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5924 write.c (fixup_segment): check for signed .word overflow if
5925 WARN_SIGNED_OVERFLOW_WORD.
5927 * write.c (fixup_segment): fixed missing parens in expression
5928 checking for byte or word overflow.

5944 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5946 * input-scrub.c (input_scrub_push): call input_file_begin, not
5948 messages.c (as_perror): print ": " between the passed in error and
5949 the strerror, like perror does.

5954 From Steve Chamberlain:
5955 Makefile.in: Handle m68*-*-coff*.
5956 read.c, read.h: add mult argument to s_space
5958 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5959 Motorola and MIT syntax; gas can now assemble either type of

5968 (fixup_segment) set fx_subsy to 0.
5969 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5971 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5974 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5976 * Makefile.in (LIBS): Include opcode library.

6001 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6003 * config/tc-m68k.c (init_table): Now const. Always include 68851
6004 data, so that "bc" is available to 68040 cache instructions.
6005 Added "tt0", "tt1", and 68ec030 variants.
6006 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6007 (enum _register): Added TT0, TT1.
6008 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6009 line number correctly in "internal error" messages. Don't print
6010 architecture-mismatch message for operand errors.
6012 From Colin Smith (colin@wrs.com):
6013 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6014 than install_operand.

6030 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6031 so that we can assemble hand-written libgcc code.

6035 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6036 has already been formatted (but may still contain %-characters).
6039 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6041 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6042 written with indirection on the last two operands, which can be
6043 either data or address registers. Added a new operand type 'r'
6044 which accepts either register type. Added '(' to notend stuff in
6045 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6047 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6061 (relax_align): If linkrelax, provide extra padding.
6063 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6064 their not having symbols associated.
6066 * tc-i960.c (norelax, instrument_branches): Default initializer is
6068 (linkrelax): Delete variable definition.

6092 being used with args swapped, causing occasional lossage when
6093 refilling buffers after an include file.

6097 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6098 version. Discard bogus DONTDEF version.

6101 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6103 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6104 selected architecture, print a message saying so and listing what

6155 processor/opcode mismatch, so reword the error message.
6156 (md_assemble): If no CPU has been set (even if FPU/PMMU
6157 characteristics have been), default to 68020. Don't need extra
6158 quotes around error string.

6240 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6242 * write.c (write_object_file): keep the fix_tail clean, which
6243 fixes a bug in -R where relocations were being lost.
6245 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6247 * configure.in: recognize m680x0 as having sun3 emulation mode for

6292 start addresses to match required alignment.
6294 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6296 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6297 where gcc looks for it.
6299 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6301 * Makefile.in: Changed some lines to be less confusing for some

6367 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6369 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6371 * expr.c (operand): if can't work out what sort of operand it is,
6372 then look through FLT_CHARS for a hint.
6374 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6376 * Makefile.in, configure.in: removed traces of namesubdir,
6377 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6378 copyrights to '92, changed some from Cygnus to FSF.
6380 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6381 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6382 copyrights to '92, changed some from Cygnus to FSF.
6384 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6386 * expr.c: If an expression is single comma, then return with
6387 SEG_ABSENT rather than an error - since the sparc front end does
6388 really strange things with things like fbge,a
6390 * as.h: include bfd.h if using many sections
6391 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6392 local labels didn't work.
6393 * listing.c (list_symbol_table): don't core dump when there's no
6395 * write.c, write.h: call fix_new with the right number of args on
6397 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6400 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6402 * app.c: MRI compatibility - allow single quote to start a string.
6403 * as.c: fix typo recently introduced.
6404 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6405 * expr.c: Much rewriting, to accomodate MRI syntax for
6406 expressions. Also easier to read now.
6407 * listing.c: Put back defuns
6408 * read.c: modified to accept MRI syntax, put back listing pseudo
6409 ops so that an assembler built with NO_LISTING ignores list ops
6411 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6412 machine is a SPARC or a 29K.
6413 * config/obj-aout.c: added s_sect pseudo op
6414 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6415 fill in the timestamp.
6416 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6417 anymore, define all the relocs which the tc-<x> bit will use so we
6418 can translate from them to the coff types.
6419 * config/tc-a29k.c: reloc_type isn't ane enum any more
6420 * config/tc-m68k.c: Added NO_RELOC definition.
6422 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6424 * Makefile.in: put header files before C source for TAGS; remove
6425 references to non-existent syscalls.h.
6427 * read.c, write.c subsegs.c: back out the .bss changes.
6429 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6431 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6435 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6437 * symbols.c (local_label_name): symbols now start with ^A.
6439 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6440 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6441 generate these sections. .align: will use NOP_OPCODE or 0
6442 for padding. This is just for being nice to the
6445 * expr.c (operand): changed to generate local label "\001L0"
6446 starting with a ^A so that it is recognized as a local label.
6448 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6450 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6451 i/o opcodes - inb, inw, outb and outw. string manipulation with
6452 att syntax - scmp, slod, smov, ssca, ssto.
6454 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6455 to just after .file .
6457 In obj_crawl_symbol_chain() where it tries to put the external
6458 symbols apart, with the condition:
6459 (!S_IS_DEFINED(symbolP) &&
6460 !S_IS_DEBUG(symbolP) &&
6461 !SF_GET_STATICS(symbolP))
6462 it was moving too many symbols out. So I switch it back to the
6464 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6466 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6467 so that we don't use the F_RELFLG which make the linker complain
6468 that somebody has stripped the relocation info.
6470 Also, the AIX ld program require that the relocation table
6471 is sorted by r_vaddr like the standard ATT assembler does.
6473 [he also changed the sizeof(struct ...)'s into the coff
6474 style FOOSZ macros. I'm not sure this is right, but I can't
6475 remember why. xoxorich.]
6477 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6479 * Makefile.in, configure.in, doc: use the doc. Build it, install

6484 * read.c: white space and comments only.
6486 * configure.in: use the new atof-ns32.c for ns32k.
6488 * write.c: comment change only.
6490 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6491 aren't yet integrated.
6493 * tc-i860.[hc]: blew off the dust. Something must still be done
6494 about conflicting relocation types.
6496 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6499 * tc-i960.c, tc-sparc.c: white space and comments only.
6501 * tc-a29k.h: delete duplicate macro definition.
6503 * new file atof-ns32k.c copied from hack's last unreleased gas.
6505 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6507 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6510 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6511 ChangeLog's prior to this are sketchy at best. I have logs.
6512 They just aren't ChangeLogs.
6516 version-control: never
