15 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
16 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
18 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
19 branch with an instruction that uses $at, in case the branch is
21 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
22 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
23 to make it pcrel_offset.
24 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
25 reloc->address; another gruesome hack to get gas reloc handling to
28 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
30 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
33 (emit_insn): New function.
34 (md_assemble): Call it.
35 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
37 (lituse_pending): New variable. Set by anything that generates a
38 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
39 tested by code that might want to emit a LITUSE reloc.
40 (emit_unaligned_io): New function. Currently calls md_assemble,
41 but it should eventually be converted to generate the insn itself
42 and call emit_insn directly.
43 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
44 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
45 emit_bis_r): Likewise.
46 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.

50 unaligned memory access macros.
51 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
52 the value can't be resolved.
54 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
56 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
57 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
58 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
60 (mips_force_relocation): New function.
61 (md_apply_fix): Set fixP->fx_done appropriately.
62 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

70 * config/tc-mips.c (enum mips_pic_level): New enum.
71 (mips_pic): Change from int to enum mips_pic_level. Change all
72 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
73 (load_address): Handle EMBEDDED_PIC.
74 (macro): Handle EMBEDDED_PIC in all PIC cases.
75 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
76 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
77 -non_shared to use NO_PIC (this is how the Irix 5 assembler
78 works). Do not permit -G with SVR4_PIC.
79 (s_abicalls): Warn if -G was used, and force -G 0.
80 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
81 anything but a.out, not just for ELF. For ECOFF, don't generate a
82 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
84 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
86 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
88 * config/tc-hppa.c (create_new_space): Use ints, not chars as
89 parameters to avoid losing when compiling with HP CC.
90 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
92 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
94 * Makefile.in (config-stamp): If `defs' is defined, emit a
95 preprocessor directive to create a macro named by this value into
96 config.new; don't explicitly go for BFD_ASSEMBLER.
97 * configure.in: Define `defs', not `BFDDEF'. Set it to
98 MANY_SEGMENTS for any obj-coffbfd target.
99 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
100 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
102 (LOCAL_LOADLIBES): Deleted.
103 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
104 * config/m88kcoff.mt (TDEFINES): Ditto.

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

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

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

2363 i386) as developmental. Deleted cases matching some generic names
2364 in favor of more specific names. (E.g., when we get Alpha

2375 * read.c (next_char_of_string): Limit octal character constants to
2378 * config/tc-hppa.h: Major cleanup. Use GNU-style comments. Warn
2379 against placing additional object-file dependent code here. Warn
2380 against contaminating all of GAS with the internals of tc-hppa.c
2381 through inclusion of tc-hppa.h. Delete all forward declarations
2382 for functions only used within tc-hppa.c, likewise for structures,
2383 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2384 conditional code in a few small places.
2386 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2387 structures, global variables, forward declarations together.

2389 conditional code -- try to group conditional code together
2390 into a few places. Make all functions and variables which
2391 are only used within tc-hppa.c static. PARAMize all functions.
2392 Add comments to functions. Delete unused functions, variables,
2393 #defines, etc. Delete unused members within structures. Delete
2394 ldil;ble hacks -- it is believed they were installed to work
2395 around old gas bugs. Avoid using mixed case for local
2396 functions, variables, and structures. Fix formatting problems
2397 not found by GNU-indent. Add FIXME notices for things which
2398 should be worked on the near future. Delete lots of old
2399 useless (1.36 PA-SOM) code.

2411 which do not involve function symbols.
2413 * config/tc-hppa.h: Reindent with GNU-indent. Delete references

2428 a multiple of the section alignment rather than always a
2431 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

3542 * Extensive changes to permit symbols to contain any expression
3543 type and to delay the computation of the expression until the
3544 value is actually needed. This permits setting symbols to values
3545 calculated based on object code size. Expressions were changed to
3546 no longer be in a section, to stop the overloading of segment and
3547 expression type that previously occurred.
3549 * as.c (big_section, pass1_section, diff_section, absent_section):
3551 (expr_section): Added (used for dummy symbols which hold

3635 (previous_section, previous_subsection): New vars.
3636 (obj_elf_section): Save current place in case DWARF code wants us
3637 to pop back to it. Handle unquoted section name as well as quoted
3638 section name. Don't crash on invalid strings.

3660 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
3661 calculating opP->isiz; this permits the expression size to be
3662 determined as well, later on.
3664 * expr.c (clean_up_expression): Don't cancel the subtraction of
3667 * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R,

3676 Fri Jul 16 08:56:04 1993 Ian Lance Taylor (ian@cygnus.com)
3678 * read.c (float_cons): Simplified parsing logic. If
3679 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
3681 * symbols.c (colon): Rather than a special case for TC_HPPA,
3682 use new macro tc_frob_label.
3683 * config/tc-hppa.h (tc_frob_label): Define.
3685 * config/tc-mips.c: Many changes to support simple assembler

4841 source directory, if that's not the current directory.

4869 avoid some redefinition complaints on some systems.
4870 (const, volatile): Don't need these conditionally defined if we
4871 use CONST and VOLATILE from ansidecl.h.
4872 (seg_name): Use CONST, not const.
4874 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4876 * config/tc-mips.c: Reindented to GNU standards.

4909 * Makefile.in (targ-cpu.o): Depend on config.h.
4911 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4913 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4914 dropping a space immediately following an identifier.

4916 lines; I don't think that can be done portably.
4917 * config/tc-mips.c (macro): Use $AT if target register is zero in
4918 load instruction, which it can be for a floating point load.
4920 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4941 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4943 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4944 to be on a single line.

4992 prototypes for all static functions. Moved existing minimal
4993 debugging format support info #ifndef OBJ_ECOFF blocks.

5042 * make-gas.com: Find obstack.obj if it's not in the current
5044 * read.c (s_ignore): Don't declare is_end_of_line. It's
5045 redundant, and triggers a VMS gcc compiler bug.
5047 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5048 current segment as an argument. (Ignored in all cases but VMS.)
5049 All callers and definitions changed.

5346 md_relax_table): Use default zero initialization.
5347 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5348 latter, instead of selecting with preprocessor conditionals.
5350 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5352 * configure.in: recognise all sparclite variants
5354 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5362 * expr.c (operand): If character other than comma or newline is a
5363 logical end-of-line character, use the newline case.
5364 From Eric Youngdale:
5365 (operand): Set X_add_number field for floating-point numbers.
5366 (operand): Treat zero byte as end-of-operand.
5368 * configure.in (per-target): Look for with_bfd_assembler option.
5369 For now, only accept "no", until the merge is done.
5371 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5372 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5374 * read.c: Finish conversion to S_* macros in the VMS only
5375 parts of the program. Add "const" modifier to hex_value.
5376 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5378 * expr.c: Add "const" modifier to hex_value.
5379 * symbols.c: Finish conversion to S_* macros in the VMS only
5380 parts of the program. Add "const" modifier to
5381 md_[long,short]_jump_size. Remove declaration of const_flag
5382 (which will be declared in obj-vms.h).
5383 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5384 Fix arguments to VMS_write_object_file.
5385 * config-gas.com: New file. Script for VMS systems to set up the
5386 configuration to build gas for VMS, and create config.status.
5387 * make-gas.com: Redone to work with new scheme.
5388 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5390 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5391 will swap bytes if needed on a big endian system. Use throughout
5393 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5394 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5395 types of malformed stabs. Change parsing algorithm so that we are
5396 more certain of having all of the information that we need on hand.
5397 * obj-vms.c (final_forward_reference): New function, used to help
5398 resolve the data types of as many struct elements as possible
5399 when some part of the struct is not fully defined by the compiler.

5402 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5403 as symbols as well in the object file. Look for external functions
5404 that start with "__vt.", and turn them into variables, since the
5405 g++ compiler is incapable of doing this.
5406 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5408 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5409 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5410 have the name of the source file yet.
5411 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5413 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5415 * read.c (s_data): Always use "data_section", since it'll map to
5416 SEG_DATA or SEG_E1 if needed.
5417 (s_lcomm): Likewise with bss_section.
5418 (s_fill): Use memset, not bzero.
5420 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5442 (big_section, reg_section, pass1_section, diff_section,
5443 absent_section, text_section, data_section, bss_section): If
5444 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5445 mapping to segT enum values.
5446 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5447 if these are used or defined, if BFD_ASSEMBLER.
5448 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5449 subseg_new split into two functions.
5450 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5452 * as.h (volatile): Don't define if already defined.
5453 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5455 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5456 declare with format attribute for -Wformat checking.
5458 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5460 * app.c, config/tc-*.c: Don't include read.h, since it is already
5463 * These are based on patches from Minh Tran-le
5464 <mtranle@paris.intellicorp.com>.
5465 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5466 obj_format coffbfd and gas_target i386coff for target.
5467 (i[34]86-*-isc*): New host (uses sysv).
5468 * config/i386aix.mt: Removed (no longer used).
5469 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5471 (LDFLAGS): Added, defined as -shlib.
5472 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5473 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5474 (DOT_LABEL_PREFIX): Define.
5475 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5476 name rather than L0\001.
5477 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5479 * symbols.c, symbols.h (local_bss_counter): Removed.
5480 * write.c (write_object_file): bss no longer uses

5488 (size_section): Restored sanity check.
5489 (do_relocs_for): Base section address on s_paddr rather than
5490 computing it. Adjust a29k R_IHIHALF special case to account for
5491 section paddr (used to require paddr to be zero). If there are no
5492 reclos, set s_relptr to 0. Set relocation size in object_headers.
5493 (fill_section): Always set s_vaddr here, removing
5494 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5495 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5496 Set STYP_INFO for .comment.
5497 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5498 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5500 H_{SET,GET}_* macros.
5501 (do_linenos_for): Set lineno size in object_headers.
5502 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5503 set s_vaddr here. If string_byte_count remains 4, set it back to
5504 0, and only write strings out if there are some. Call
5505 fill_section before do_relocs_for and do_linenos_for.
5506 (obj_coff_section): Handle optional quoted second argument giving
5507 section characteristics.
5508 (obj_coff_bss): Added to handle .bss.
5509 (obj_coff_ident): Added to handle .ident (puts string in .comment

5529 (do_scrub_next_char): For \", return " not '.
5530 (symbol_chars): Now const.
5532 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5533 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5535 * config/obj-coff.h: Don't use #elif.
5537 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5538 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5540 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5542 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5562 SEG_BSS, fill with NOP_OPCODE.
5563 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5564 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5565 using ZERO_BASED_SEGMENTS.
5566 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5567 never set segment address for SEG_E2 (.bss) and don't write out
5568 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5569 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5570 definitions, and don't merge tags with non-tags. Check for .bf
5571 rather than just checking whether the second character is b and
5572 the third character is f.
5573 (obj_coff_val): gcc can generate values which we don't handle
5574 correctly; discard information for now, since it only affects the
5575 debugging information.
5576 (tag_find_or_name): Don't insert tags in the symbol table.
5577 (yank_symbols): Don't merge labels.
5578 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5598 power-of-two alignment for .align.
5600 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
5601 and leave everything else alone.

5724 could be doing emulation.
5726 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5729 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5758 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5760 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5761 constant will not fit in an immediate field.
5762 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5799 * Support for i386-sysv.
5800 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5838 * tc-z8k.c: lots of bug fixes
5840 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5842 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5843 #elif, since it is not supported by old compilers.
5844 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5845 couple of expressions in tc-m68k.c.
5847 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5849 * read.c (cons): If NO_RELOC is defined, use it.
5851 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5853 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5855 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5856 local labels to start with a .) and set REGISTER_PREFIX to %.
5857 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5859 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5873 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5875 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5876 sections starting from zero, rather than making them consecutive.
5877 This makes subsequent reloc calculations easier, esp if the object
5878 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5879 allocate lcomm in .data rather than in .bss. It seems that some
5880 tools can't cope with a non-zero sized bss before linkage.
5882 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5884 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5903 * Makefile.in (install): if $(tooldir) exists, install as in
5906 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5908 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5909 .word is < -32768 or > 32767. The -J flag causes the error to be
5910 ignored. This is to catch over-sized switches generated by gcc on
5911 systems which don't support the broken .word hack.
5912 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5913 write.c (fixup_segment): check for signed .word overflow if
5914 WARN_SIGNED_OVERFLOW_WORD.
5916 * write.c (fixup_segment): fixed missing parens in expression
5917 checking for byte or word overflow.

5933 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5935 * input-scrub.c (input_scrub_push): call input_file_begin, not
5937 messages.c (as_perror): print ": " between the passed in error and
5938 the strerror, like perror does.

5943 From Steve Chamberlain:
5944 Makefile.in: Handle m68*-*-coff*.
5945 read.c, read.h: add mult argument to s_space
5947 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5948 Motorola and MIT syntax; gas can now assemble either type of
5950 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5957 (fixup_segment) set fx_subsy to 0.
5958 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5960 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5963 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5965 * Makefile.in (LIBS): Include opcode library.
5967 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5990 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5992 * config/tc-m68k.c (init_table): Now const. Always include 68851
5993 data, so that "bc" is available to 68040 cache instructions.
5994 Added "tt0", "tt1", and 68ec030 variants.
5995 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5996 (enum _register): Added TT0, TT1.
5997 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5998 line number correctly in "internal error" messages. Don't print
5999 architecture-mismatch message for operand errors.
6001 From Colin Smith (colin@wrs.com):
6002 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6003 than install_operand.

6019 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6020 so that we can assemble hand-written libgcc code.

6024 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6025 has already been formatted (but may still contain %-characters).
6028 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6030 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6031 written with indirection on the last two operands, which can be
6032 either data or address registers. Added a new operand type 'r'
6033 which accepts either register type. Added '(' to notend stuff in
6034 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6036 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6052 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6053 their not having symbols associated.
6055 * tc-i960.c (norelax, instrument_branches): Default initializer is
6057 (linkrelax): Delete variable definition.

6086 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6087 version. Discard bogus DONTDEF version.

6092 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6093 selected architecture, print a message saying so and listing what

6144 processor/opcode mismatch, so reword the error message.
6145 (md_assemble): If no CPU has been set (even if FPU/PMMU
6146 characteristics have been), default to 68020. Don't need extra
6147 quotes around error string.

6229 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6231 * write.c (write_object_file): keep the fix_tail clean, which
6232 fixes a bug in -R where relocations were being lost.
6234 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6236 * configure.in: recognize m680x0 as having sun3 emulation mode for

6281 start addresses to match required alignment.
6283 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6285 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6286 where gcc looks for it.
6288 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6290 * Makefile.in: Changed some lines to be less confusing for some

6356 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6358 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6360 * expr.c (operand): if can't work out what sort of operand it is,
6361 then look through FLT_CHARS for a hint.
6363 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6365 * Makefile.in, configure.in: removed traces of namesubdir,
6366 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6367 copyrights to '92, changed some from Cygnus to FSF.
6369 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6370 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6371 copyrights to '92, changed some from Cygnus to FSF.
6373 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6375 * expr.c: If an expression is single comma, then return with
6376 SEG_ABSENT rather than an error - since the sparc front end does
6377 really strange things with things like fbge,a
6379 * as.h: include bfd.h if using many sections
6380 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6381 local labels didn't work.
6382 * listing.c (list_symbol_table): don't core dump when there's no
6384 * write.c, write.h: call fix_new with the right number of args on
6386 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6389 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6391 * app.c: MRI compatibility - allow single quote to start a string.
6392 * as.c: fix typo recently introduced.
6393 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6394 * expr.c: Much rewriting, to accomodate MRI syntax for
6395 expressions. Also easier to read now.
6396 * listing.c: Put back defuns
6397 * read.c: modified to accept MRI syntax, put back listing pseudo
6398 ops so that an assembler built with NO_LISTING ignores list ops
6400 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6401 machine is a SPARC or a 29K.
6402 * config/obj-aout.c: added s_sect pseudo op
6403 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6404 fill in the timestamp.
6405 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6406 anymore, define all the relocs which the tc-<x> bit will use so we
6407 can translate from them to the coff types.
6408 * config/tc-a29k.c: reloc_type isn't ane enum any more
6409 * config/tc-m68k.c: Added NO_RELOC definition.
6411 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6413 * Makefile.in: put header files before C source for TAGS; remove
6414 references to non-existent syscalls.h.
6416 * read.c, write.c subsegs.c: back out the .bss changes.
6418 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6420 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6424 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6426 * symbols.c (local_label_name): symbols now start with ^A.
6428 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6429 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6430 generate these sections. .align: will use NOP_OPCODE or 0
6431 for padding. This is just for being nice to the
6434 * expr.c (operand): changed to generate local label "\001L0"
6435 starting with a ^A so that it is recognized as a local label.
6437 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6439 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6440 i/o opcodes - inb, inw, outb and outw. string manipulation with
6441 att syntax - scmp, slod, smov, ssca, ssto.
6443 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6444 to just after .file .
6446 In obj_crawl_symbol_chain() where it tries to put the external
6447 symbols apart, with the condition:
6448 (!S_IS_DEFINED(symbolP) &&
6449 !S_IS_DEBUG(symbolP) &&
6450 !SF_GET_STATICS(symbolP))
6451 it was moving too many symbols out. So I switch it back to the
6453 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6455 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6456 so that we don't use the F_RELFLG which make the linker complain
6457 that somebody has stripped the relocation info.
6459 Also, the AIX ld program require that the relocation table
6460 is sorted by r_vaddr like the standard ATT assembler does.
6462 [he also changed the sizeof(struct ...)'s into the coff
6463 style FOOSZ macros. I'm not sure this is right, but I can't
6464 remember why. xoxorich.]
6466 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6468 * Makefile.in, configure.in, doc: use the doc. Build it, install
6471 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6473 * read.c: white space and comments only.
6475 * configure.in: use the new atof-ns32.c for ns32k.
6477 * write.c: comment change only.
6479 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6480 aren't yet integrated.
6482 * tc-i860.[hc]: blew off the dust. Something must still be done
6483 about conflicting relocation types.
6485 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6488 * tc-i960.c, tc-sparc.c: white space and comments only.
6490 * tc-a29k.h: delete duplicate macro definition.
6492 * new file atof-ns32k.c copied from hack's last unreleased gas.
6494 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6496 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6499 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6500 ChangeLog's prior to this are sketchy at best. I have logs.
6501 They just aren't ChangeLogs.
6505 version-control: never
