3 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
4 branch with an instruction that uses $at, in case the branch is
6 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
7 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
8 to make it pcrel_offset.
9 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
10 reloc->address; another gruesome hack to get gas reloc handling to
13 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
15 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
18 (emit_insn): New function.
19 (md_assemble): Call it.
20 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
22 (lituse_pending): New variable. Set by anything that generates a
23 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
24 tested by code that might want to emit a LITUSE reloc.
25 (emit_unaligned_io): New function. Currently calls md_assemble,
26 but it should eventually be converted to generate the insn itself
27 and call emit_insn directly.
28 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
29 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
30 emit_bis_r): Likewise.
31 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
32 (alpha_ip, label get_macro): Don't emit the final instruction if
34 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
35 unaligned memory access macros.
36 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
37 the value can't be resolved.
39 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
41 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
42 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
43 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
45 (mips_force_relocation): New function.
46 (md_apply_fix): Set fixP->fx_done appropriately.
47 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to
49 * config/tc-mips.h (TC_FORCE_RELOCATION): Define.
50 (mips_force_relocation): Declare.
51 (TC_HANDLE_FX_DONE): Define.
53 Tue Mar 22 13:58:37 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
55 * config/tc-mips.c (enum mips_pic_level): New enum.
56 (mips_pic): Change from int to enum mips_pic_level. Change all
57 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
58 (load_address): Handle EMBEDDED_PIC.
59 (macro): Handle EMBEDDED_PIC in all PIC cases.
60 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
61 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
62 -non_shared to use NO_PIC (this is how the Irix 5 assembler
63 works). Do not permit -G with SVR4_PIC.
64 (s_abicalls): Warn if -G was used, and force -G 0.
65 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
66 anything but a.out, not just for ELF. For ECOFF, don't generate a
67 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
69 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
71 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
73 * config/tc-hppa.c (create_new_space): Use ints, not chars as
74 parameters to avoid losing when compiling with HP CC.
75 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
77 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
79 * Makefile.in (config-stamp): If `defs' is defined, emit a
80 preprocessor directive to create a macro named by this value into
81 config.new; don't explicitly go for BFD_ASSEMBLER.
82 * configure.in: Define `defs', not `BFDDEF'. Set it to
83 MANY_SEGMENTS for any obj-coffbfd target.
84 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
85 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
87 (LOCAL_LOADLIBES): Deleted.
88 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
89 * config/m88kcoff.mt (TDEFINES): Ditto.
90 * config/ebmon29k.mt: Deleted.
91 * config/h8300hds.mt: Deleted.
92 * config/ic960coff.mt: Deleted.
93 * config/sparc.mt: Deleted.
94 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
95 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

115 bfd_set_symtab is called.
116 (dump_section_relocs): Note whether a symbol is a section symbol
118 (adjust_reloc_syms): For now, always supply an absolute symbol for
119 fixups without symbols but not yet `done'. Use section_symbol to
120 get the symbol, instead of going directly for abs_symbol.
121 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
122 reloc is not a section symbol and is not in the symbol table.
123 (set_symtab): New function, broken out from write_object_file.
124 Counts symbol table instead of relying on an earlier count.
125 (write_object_file): Call set_symtab, but do it after potentially
126 invoking the *_frob_file macros. Don't bother counting symbols.
127 Call symbol_remove, instead of expanding it in place. Moved the
128 conditionalized `object_file_size' declaration down to
129 conditionalized block where it's used. When using the absolute
130 symbol for a fixup without a symbol, set sy_used_in_reloc.
131 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
132 the correct symbol for the absolute section.
134 * subsegs.c (section_symbol): Use symbol_new instead of
135 symbol_make, since we may want it to go into the symbol table.
136 Make the new symbol have internal linkage. If
137 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
138 symbol with the newly created GAS symbol.
139 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
140 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

145 (in_signed_range): New function.
147 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
148 (sparc_ip, label "immediate"): Reject constants for pcrel
149 instructions only if the relocation type indicates a "call"
150 instruction and the offset is within range of a "jmpl %g0". If
151 it's not in range, use the absolute section symbol plus an offset.
152 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
154 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
156 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
159 * configure.in: Eliminated all targets using obj-coff but not
160 defining BFD_ASSEMBLER; I think all such targets that are
161 supported will be matched by real CPU-OS combinations earlier in
163 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
164 some comments about the dpx2 configuration, but left it disabled,
165 since it couldn't be reached before.
166 (target a29k-amd-ebmonold): Deleted.
168 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

175 * config/tc-mips.c (mips_ip): Only accept overly large values for
176 the 'j' operand if there are no further alternatives for this
179 * config/obj-coffbfd.c (adjust_stab_section): Initialize
180 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
181 is not SEG_UNKNOWN rather than checking whether it is >= 0.
183 * config/tc-mips.c (mips_align): Take new argument, label, and use
184 it instead of global insn_label.
185 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
186 call to mips_emit_delay and pass it to mips_align.
188 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
190 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
192 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
193 argument to a .callinfo directive. Don't loop forever on errors.
195 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
196 use pre-defined registers as arguments.
198 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
200 * write.c (write_object_file): Check both S_IS_LOCAL and
201 S_IS_EXTERNAL when deciding whether to discard a symbol.
203 * config-gas.com: Scan Makefile.in, not version.c, for current
204 version number. Delete all versions of temp files when finished
205 with them. Create config.h.
207 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
208 values to reduce number of lookups with S_GET_VALUE. Skip debug
209 symbols to avoid "a really nasty bug". (From Holger Teutsch,
210 holger@botbso.rhein-main.de.)
211 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
212 field. (Also from Holger Teutsch.) Watch for a would-be register
213 mask that spans frags.
215 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
216 this_base, not line_base. (Patch from Andreas Arens,
217 ari@obelix.av.rwth-aachen.de.)
219 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
220 look local if they're exported or undefined. Used to be done for
223 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
224 Get it from the looked-up symbol, instead of using the string from
225 the input stream, which is no longer null-terminated.
226 (LEX_PCT): New macro, defaults to 0.
227 (lex_type): Use it for `%'.
229 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
230 (vip_op): Now static, and returns void. Callers changed. Added
232 (vip): Ditto. Call as_fatal directly if a program bug is

2232 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2233 the table, require that the one without bit 0x1000000 set come

2347 still being worked on. Mark Elf configurations (except sparc and
2348 i386) as developmental. Deleted cases matching some generic names
2349 in favor of more specific names. (E.g., when we get Alpha

2367 for functions only used within tc-hppa.c, likewise for structures,
2368 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2369 conditional code in a few small places.
2371 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2372 structures, global variables, forward declarations together.

3527 * Extensive changes to permit symbols to contain any expression
3528 type and to delay the computation of the expression until the
3529 value is actually needed. This permits setting symbols to values
3530 calculated based on object code size. Expressions were changed to
3531 no longer be in a section, to stop the overloading of segment and
3532 expression type that previously occurred.
3534 * as.c (big_section, pass1_section, diff_section, absent_section):
3536 (expr_section): Added (used for dummy symbols which hold

3620 (previous_section, previous_subsection): New vars.
3621 (obj_elf_section): Save current place in case DWARF code wants us
3622 to pop back to it. Handle unquoted section name as well as quoted
3623 section name. Don't crash on invalid strings.

3645 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
3646 calculating opP->isiz; this permits the expression size to be
3647 determined as well, later on.
3649 * expr.c (clean_up_expression): Don't cancel the subtraction of
3652 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

3661 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
3663 * read.c (float_cons): Simplified parsing logic. If
3664 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
3666 * symbols.c (colon): Rather than a special case for TC_HPPA,
3667 use new macro tc_frob_label.
3668 * config/tc-hppa.h (tc_frob_label): Define.

3707 * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust

4826 source directory, if that's not the current directory.
4828 * configure.in (per-host): Accept MIPS host with BSD version

4854 avoid some redefinition complaints on some systems.
4855 (const, volatile): Don't need these conditionally defined if we
4856 use CONST and VOLATILE from ansidecl.h.
4857 (seg_name): Use CONST, not const.
4859 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4861 * config/tc-mips.c: Reindented to GNU standards.

4865 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4866 (fixup_segment): Add a29k special case; the linker is not prepared
4867 to see a segment offset here.

4872 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4874 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4875 srcdir, might be in objdir.

4894 * Makefile.in (targ-cpu.o): Depend on config.h.
4896 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4898 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4899 dropping a space immediately following an identifier.
4900 * expr.c, write.c: Rewrote assert expressions to not use multiple
4901 lines; I don't think that can be done portably.
4902 * config/tc-mips.c (macro): Use $AT if target register is zero in
4903 load instruction, which it can be for a floating point load.
4905 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4926 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4928 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4929 to be on a single line.
4931 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4933 * Makefile.in (config.h): Create file, writing out definitions of

4977 prototypes for all static functions. Moved existing minimal
4978 debugging format support info #ifndef OBJ_ECOFF blocks.

5027 * make-gas.com: Find obstack.obj if it's not in the current
5029 * read.c (s_ignore): Don't declare is_end_of_line. It's
5030 redundant, and triggers a VMS gcc compiler bug.
5032 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5033 current segment as an argument. (Ignored in all cases but VMS.)
5034 All callers and definitions changed.

5163 * read.c: Don't include ctype.h.
5164 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
5165 for now; should be machine-dependent.
5167 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format

5331 md_relax_table): Use default zero initialization.
5332 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5333 latter, instead of selecting with preprocessor conditionals.
5335 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5337 * configure.in: recognise all sparclite variants

5347 * expr.c (operand): If character other than comma or newline is a
5348 logical end-of-line character, use the newline case.
5349 From Eric Youngdale:
5350 (operand): Set X_add_number field for floating-point numbers.
5351 (operand): Treat zero byte as end-of-operand.
5353 * configure.in (per-target): Look for with_bfd_assembler option.
5354 For now, only accept "no", until the merge is done.
5356 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5357 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5363 * expr.c: Add "const" modifier to hex_value.
5364 * symbols.c: Finish conversion to S_* macros in the VMS only
5365 parts of the program. Add "const" modifier to
5366 md_[long,short]_jump_size. Remove declaration of const_flag
5367 (which will be declared in obj-vms.h).
5368 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5369 Fix arguments to VMS_write_object_file.
5370 * config-gas.com: New file. Script for VMS systems to set up the
5371 configuration to build gas for VMS, and create config.status.
5372 * make-gas.com: Redone to work with new scheme.
5373 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5375 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5376 will swap bytes if needed on a big endian system. Use throughout
5378 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5379 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5380 types of malformed stabs. Change parsing algorithm so that we are
5381 more certain of having all of the information that we need on hand.
5382 * obj-vms.c (final_forward_reference): New function, used to help
5383 resolve the data types of as many struct elements as possible
5384 when some part of the struct is not fully defined by the compiler.

5387 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5388 as symbols as well in the object file. Look for external functions
5389 that start with "__vt.", and turn them into variables, since the
5390 g++ compiler is incapable of doing this.
5391 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5393 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5394 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5395 have the name of the source file yet.
5396 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5398 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5400 * read.c (s_data): Always use "data_section", since it'll map to
5401 SEG_DATA or SEG_E1 if needed.
5402 (s_lcomm): Likewise with bss_section.
5403 (s_fill): Use memset, not bzero.
5405 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5427 (big_section, reg_section, pass1_section, diff_section,
5428 absent_section, text_section, data_section, bss_section): If
5429 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5430 mapping to segT enum values.
5431 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5432 if these are used or defined, if BFD_ASSEMBLER.
5433 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5434 subseg_new split into two functions.
5435 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5437 * as.h (volatile): Don't define if already defined.
5438 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5440 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5441 declare with format attribute for -Wformat checking.
5443 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5445 * app.c, config/tc-*.c: Don't include read.h, since it is already
5448 * These are based on patches from Minh Tran-le
5449 <mtranle@paris.intellicorp.com>.
5450 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5451 obj_format coffbfd and gas_target i386coff for target.
5452 (i[34]86-*-isc*): New host (uses sysv).
5453 * config/i386aix.mt: Removed (no longer used).
5454 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5456 (LDFLAGS): Added, defined as -shlib.
5457 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5458 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5459 (DOT_LABEL_PREFIX): Define.
5460 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5461 name rather than L0\001.
5462 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5464 * symbols.c, symbols.h (local_bss_counter): Removed.
5465 * write.c (write_object_file): bss no longer uses

5473 (size_section): Restored sanity check.
5474 (do_relocs_for): Base section address on s_paddr rather than
5475 computing it. Adjust a29k R_IHIHALF special case to account for
5476 section paddr (used to require paddr to be zero). If there are no
5477 reclos, set s_relptr to 0. Set relocation size in object_headers.
5478 (fill_section): Always set s_vaddr here, removing
5479 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5480 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5481 Set STYP_INFO for .comment.
5482 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5483 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5485 H_{SET,GET}_* macros.
5486 (do_linenos_for): Set lineno size in object_headers.
5487 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5488 set s_vaddr here. If string_byte_count remains 4, set it back to
5489 0, and only write strings out if there are some. Call
5490 fill_section before do_relocs_for and do_linenos_for.
5491 (obj_coff_section): Handle optional quoted second argument giving
5492 section characteristics.
5493 (obj_coff_bss): Added to handle .bss.
5494 (obj_coff_ident): Added to handle .ident (puts string in .comment

5514 (do_scrub_next_char): For \", return " not '.
5515 (symbol_chars): Now const.
5517 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5518 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5520 * config/obj-coff.h: Don't use #elif.
5522 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5523 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5525 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5527 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5547 SEG_BSS, fill with NOP_OPCODE.
5548 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5549 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5550 using ZERO_BASED_SEGMENTS.
5551 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5552 never set segment address for SEG_E2 (.bss) and don't write out
5553 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5554 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5555 definitions, and don't merge tags with non-tags. Check for .bf
5556 rather than just checking whether the second character is b and
5557 the third character is f.
5558 (obj_coff_val): gcc can generate values which we don't handle
5559 correctly; discard information for now, since it only affects the
5560 debugging information.
5561 (tag_find_or_name): Don't insert tags in the symbol table.
5562 (yank_symbols): Don't merge labels.
5563 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5583 power-of-two alignment for .align.
5585 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
5586 and leave everything else alone.

5709 could be doing emulation.
5711 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5714 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5827 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5828 #elif, since it is not supported by old compilers.
5829 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5830 couple of expressions in tc-m68k.c.
5832 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5834 * read.c (cons): If NO_RELOC is defined, use it.

5860 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5861 sections starting from zero, rather than making them consecutive.
5862 This makes subsequent reloc calculations easier, esp if the object
5863 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5864 allocate lcomm in .data rather than in .bss. It seems that some
5865 tools can't cope with a non-zero sized bss before linkage.
5867 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5869 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5888 * Makefile.in (install): if $(tooldir) exists, install as in
5891 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5893 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5894 .word is < -32768 or > 32767. The -J flag causes the error to be
5895 ignored. This is to catch over-sized switches generated by gcc on
5896 systems which don't support the broken .word hack.
5897 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5898 write.c (fixup_segment): check for signed .word overflow if
5899 WARN_SIGNED_OVERFLOW_WORD.

5918 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5920 * input-scrub.c (input_scrub_push): call input_file_begin, not
5922 messages.c (as_perror): print ": " between the passed in error and
5923 the strerror, like perror does.

5928 From Steve Chamberlain:
5929 Makefile.in: Handle m68*-*-coff*.
5930 read.c, read.h: add mult argument to s_space
5932 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5933 Motorola and MIT syntax; gas can now assemble either type of
5935 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5941 (write_object_file) call fixup_mdeps
5942 (fixup_segment) set fx_subsy to 0.
5943 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5945 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5948 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5950 * Makefile.in (LIBS): Include opcode library.
5952 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5975 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5977 * config/tc-m68k.c (init_table): Now const. Always include 68851
5978 data, so that "bc" is available to 68040 cache instructions.
5979 Added "tt0", "tt1", and 68ec030 variants.
5980 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5981 (enum _register): Added TT0, TT1.
5982 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5983 line number correctly in "internal error" messages. Don't print
5984 architecture-mismatch message for operand errors.
5986 From Colin Smith (colin@wrs.com):
5987 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5988 than install_operand.

6004 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6005 so that we can assemble hand-written libgcc code.

6009 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6010 has already been formatted (but may still contain %-characters).
6013 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6015 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6016 written with indirection on the last two operands, which can be
6017 either data or address registers. Added a new operand type 'r'
6018 which accepts either register type. Added '(' to notend stuff in
6019 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6021 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6037 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6038 their not having symbols associated.
6040 * tc-i960.c (norelax, instrument_branches): Default initializer is
6042 (linkrelax): Delete variable definition.

6066 being used with args swapped, causing occasional lossage when
6067 refilling buffers after an include file.

6077 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6078 selected architecture, print a message saying so and listing what

6216 * write.c (write_object_file): keep the fix_tail clean, which
6217 fixes a bug in -R where relocations were being lost.
6219 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6221 * configure.in: recognize m680x0 as having sun3 emulation mode for

6268 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6270 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6271 where gcc looks for it.
6273 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6275 * Makefile.in: Changed some lines to be less confusing for some

6341 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6343 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6345 * expr.c (operand): if can't work out what sort of operand it is,
6346 then look through FLT_CHARS for a hint.
6348 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6350 * Makefile.in, configure.in: removed traces of namesubdir,

6352 copyrights to '92, changed some from Cygnus to FSF.
6354 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6355 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6356 copyrights to '92, changed some from Cygnus to FSF.
6358 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6360 * expr.c: If an expression is single comma, then return with
6361 SEG_ABSENT rather than an error - since the sparc front end does
6362 really strange things with things like fbge,a
6364 * as.h: include bfd.h if using many sections
6365 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6366 local labels didn't work.
6367 * listing.c (list_symbol_table): don't core dump when there's no
6369 * write.c, write.h: call fix_new with the right number of args on
6371 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6374 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6376 * app.c: MRI compatibility - allow single quote to start a string.
6377 * as.c: fix typo recently introduced.
6378 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6379 * expr.c: Much rewriting, to accomodate MRI syntax for
6380 expressions. Also easier to read now.
6381 * listing.c: Put back defuns
6382 * read.c: modified to accept MRI syntax, put back listing pseudo
6383 ops so that an assembler built with NO_LISTING ignores list ops
6385 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6386 machine is a SPARC or a 29K.
6387 * config/obj-aout.c: added s_sect pseudo op
6388 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6389 fill in the timestamp.
6390 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6391 anymore, define all the relocs which the tc-<x> bit will use so we
6392 can translate from them to the coff types.
6393 * config/tc-a29k.c: reloc_type isn't ane enum any more
6394 * config/tc-m68k.c: Added NO_RELOC definition.
6396 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6398 * Makefile.in: put header files before C source for TAGS; remove
6399 references to non-existent syscalls.h.
6401 * read.c, write.c subsegs.c: back out the .bss changes.
6403 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6405 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6409 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6411 * symbols.c (local_label_name): symbols now start with ^A.
6413 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6414 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6415 generate these sections. .align: will use NOP_OPCODE or 0
6416 for padding. This is just for being nice to the
6419 * expr.c (operand): changed to generate local label "\001L0"
6420 starting with a ^A so that it is recognized as a local label.
6422 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6424 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6425 i/o opcodes - inb, inw, outb and outw. string manipulation with
6426 att syntax - scmp, slod, smov, ssca, ssto.
6428 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6429 to just after .file .
6431 In obj_crawl_symbol_chain() where it tries to put the external
6432 symbols apart, with the condition:
6433 (!S_IS_DEFINED(symbolP) &&
6434 !S_IS_DEBUG(symbolP) &&
6435 !SF_GET_STATICS(symbolP))
6436 it was moving too many symbols out. So I switch it back to the
6438 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6440 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6441 so that we don't use the F_RELFLG which make the linker complain
6442 that somebody has stripped the relocation info.
6444 Also, the AIX ld program require that the relocation table
6445 is sorted by r_vaddr like the standard ATT assembler does.
6447 [he also changed the sizeof(struct ...)'s into the coff
6448 style FOOSZ macros. I'm not sure this is right, but I can't
6449 remember why. xoxorich.]
6451 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6453 * Makefile.in, configure.in, doc: use the doc. Build it, install

6458 * read.c: white space and comments only.
6460 * configure.in: use the new atof-ns32.c for ns32k.
6462 * write.c: comment change only.
6464 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6465 aren't yet integrated.
6467 * tc-i860.[hc]: blew off the dust. Something must still be done
6468 about conflicting relocation types.
6470 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6473 * tc-i960.c, tc-sparc.c: white space and comments only.
6475 * tc-a29k.h: delete duplicate macro definition.
6477 * new file atof-ns32k.c copied from hack's last unreleased gas.
6479 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6481 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6484 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6485 ChangeLog's prior to this are sketchy at best. I have logs.
6486 They just aren't ChangeLogs.
6490 version-control: never
