3 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
6 (emit_insn): New function.
7 (md_assemble): Call it.
8 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
10 (lituse_pending): New variable. Set by anything that generates a
11 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
12 tested by code that might want to emit a LITUSE reloc.
13 (emit_unaligned_io): New function. Currently calls md_assemble,
14 but it should eventually be converted to generate the insn itself
15 and call emit_insn directly.
16 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
17 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
18 emit_bis_r): Likewise.

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

33 (mips_force_relocation): New function.
34 (md_apply_fix): Set fixP->fx_done appropriately.
35 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

43 * config/tc-mips.c (enum mips_pic_level): New enum.
44 (mips_pic): Change from int to enum mips_pic_level. Change all
45 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
46 (load_address): Handle EMBEDDED_PIC.
47 (macro): Handle EMBEDDED_PIC in all PIC cases.
48 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
49 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
50 -non_shared to use NO_PIC (this is how the Irix 5 assembler
51 works). Do not permit -G with SVR4_PIC.
52 (s_abicalls): Warn if -G was used, and force -G 0.
53 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
54 anything but a.out, not just for ELF. For ECOFF, don't generate a
55 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
57 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
59 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

65 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
67 * Makefile.in (config-stamp): If `defs' is defined, emit a
68 preprocessor directive to create a macro named by this value into
69 config.new; don't explicitly go for BFD_ASSEMBLER.
70 * configure.in: Define `defs', not `BFDDEF'. Set it to
71 MANY_SEGMENTS for any obj-coffbfd target.
72 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
73 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
75 (LOCAL_LOADLIBES): Deleted.
76 * config/m68kcoff.mt (TDEFINES): Don't define those macros.

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

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

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

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

198 holger@botbso.rhein-main.de.)
199 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
200 field. (Also from Holger Teutsch.) Watch for a would-be register
201 mask that spans frags.
203 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
204 this_base, not line_base. (Patch from Andreas Arens,
205 ari@obelix.av.rwth-aachen.de.)

208 look local if they're exported or undefined. Used to be done for
211 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

213 the input stream, which is no longer null-terminated.
214 (LEX_PCT): New macro, defaults to 0.
215 (lex_type): Use it for `%'.
217 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
218 (vip_op): Now static, and returns void. Callers changed. Added

1929 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
1930 standard hpux include files to pick up various function decls.

1998 pass new argument for i, j and o cases.
1999 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2002 rather than hard coded constants.
2003 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

2220 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2221 the table, require that the one without bit 0x1000000 set come

2330 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
2332 * configure.in: Set bfd_gas for all sparc targets. Added facility
2333 for keeping or rejecting configurations still under development;
2334 default is to assume production environment, and reject configs
2335 still being worked on. Mark Elf configurations (except sparc and
2336 i386) as developmental. Deleted cases matching some generic names
2337 in favor of more specific names. (E.g., when we get Alpha
2338 support, we'll still only support VMS for Vax.)

2341 * config/tc-sparc.c (md_end): Function deleted.
2342 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2352 against placing additional object-file dependent code here. Warn
2353 against contaminating all of GAS with the internals of tc-hppa.c
2354 through inclusion of tc-hppa.h. Delete all forward declarations
2355 for functions only used within tc-hppa.c, likewise for structures,
2356 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2357 conditional code in a few small places.
2359 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2360 structures, global variables, forward declarations together.

2362 conditional code -- try to group conditional code together
2363 into a few places. Make all functions and variables which
2364 are only used within tc-hppa.c static. PARAMize all functions.
2365 Add comments to functions. Delete unused functions, variables,
2366 #defines, etc. Delete unused members within structures. Delete
2367 ldil;ble hacks -- it is believed they were installed to work
2368 around old gas bugs. Avoid using mixed case for local
2369 functions, variables, and structures. Fix formatting problems
2370 not found by GNU-indent. Add FIXME notices for things which
2371 should be worked on the near future. Delete lots of old
2372 useless (1.36 PA-SOM) code.
2374 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
2375 field of the fixS structure. Needed to build unwind

3515 * Extensive changes to permit symbols to contain any expression
3516 type and to delay the computation of the expression until the
3517 value is actually needed. This permits setting symbols to values
3518 calculated based on object code size. Expressions were changed to
3519 no longer be in a section, to stop the overloading of segment and
3520 expression type that previously occurred.
3522 * as.c (big_section, pass1_section, diff_section, absent_section):

3634 calculating opP->isiz; this permits the expression size to be
3635 determined as well, later on.

4728 than ECOFF line number information.
4729 (obj_ecoff_stab): Accept non-zero values for stabs line number.

4790 dependencies are read, not when they are used).
4792 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4793 a29k .bss section; the mondfe program doesn't like it.

4842 avoid some redefinition complaints on some systems.
4843 (const, volatile): Don't need these conditionally defined if we
4844 use CONST and VOLATILE from ansidecl.h.
4845 (seg_name): Use CONST, not const.
4847 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4849 * config/tc-mips.c: Reindented to GNU standards.

4853 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4854 (fixup_segment): Add a29k special case; the linker is not prepared
4855 to see a segment offset here.

4860 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4862 * Makefile.in: add dvi target; as-$(config).texinfo might live in

4882 * Makefile.in (targ-cpu.o): Depend on config.h.
4884 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4886 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4887 dropping a space immediately following an identifier.
4888 * expr.c, write.c: Rewrote assert expressions to not use multiple
4889 lines; I don't think that can be done portably.
4890 * config/tc-mips.c (macro): Use $AT if target register is zero in
4891 load instruction, which it can be for a floating point load.
4893 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4914 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4916 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4917 to be on a single line.

4965 prototypes for all static functions. Moved existing minimal
4966 debugging format support info #ifndef OBJ_ECOFF blocks.

4969 all callers accordingly.
4970 (tc_get_register): Renamed from get_register, and made non-static.
4972 * config/mips-big.mt, config/mips-lit.mt: New files. Define

5015 * make-gas.com: Find obstack.obj if it's not in the current
5017 * read.c (s_ignore): Don't declare is_end_of_line. It's
5018 redundant, and triggers a VMS gcc compiler bug.
5020 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5021 current segment as an argument. (Ignored in all cases but VMS.)
5022 All callers and definitions changed.

5153 for now; should be machine-dependent.
5155 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
5156 targets, forcing BFD use.

5319 md_relax_table): Use default zero initialization.
5320 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5321 latter, instead of selecting with preprocessor conditionals.
5323 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5325 * configure.in: recognise all sparclite variants

5335 * expr.c (operand): If character other than comma or newline is a
5336 logical end-of-line character, use the newline case.
5337 From Eric Youngdale:
5338 (operand): Set X_add_number field for floating-point numbers.
5339 (operand): Treat zero byte as end-of-operand.
5341 * configure.in (per-target): Look for with_bfd_assembler option.
5342 For now, only accept "no", until the merge is done.
5344 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5345 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5351 * expr.c: Add "const" modifier to hex_value.
5352 * symbols.c: Finish conversion to S_* macros in the VMS only
5353 parts of the program. Add "const" modifier to
5354 md_[long,short]_jump_size. Remove declaration of const_flag
5355 (which will be declared in obj-vms.h).
5356 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5357 Fix arguments to VMS_write_object_file.
5358 * config-gas.com: New file. Script for VMS systems to set up the
5359 configuration to build gas for VMS, and create config.status.
5360 * make-gas.com: Redone to work with new scheme.
5361 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5363 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which

5366 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5367 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5368 types of malformed stabs. Change parsing algorithm so that we are
5369 more certain of having all of the information that we need on hand.
5370 * obj-vms.c (final_forward_reference): New function, used to help
5371 resolve the data types of as many struct elements as possible
5372 when some part of the struct is not fully defined by the compiler.

5375 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5376 as symbols as well in the object file. Look for external functions

5378 g++ compiler is incapable of doing this.
5379 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5381 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5382 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5383 have the name of the source file yet.
5384 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5386 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5388 * read.c (s_data): Always use "data_section", since it'll map to
5389 SEG_DATA or SEG_E1 if needed.
5390 (s_lcomm): Likewise with bss_section.
5391 (s_fill): Use memset, not bzero.
5393 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5415 (big_section, reg_section, pass1_section, diff_section,
5416 absent_section, text_section, data_section, bss_section): If
5417 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5418 mapping to segT enum values.
5419 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5420 if these are used or defined, if BFD_ASSEMBLER.
5421 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5422 subseg_new split into two functions.
5423 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5425 * as.h (volatile): Don't define if already defined.
5426 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5428 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5429 declare with format attribute for -Wformat checking.
5431 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5433 * app.c, config/tc-*.c: Don't include read.h, since it is already
5436 * These are based on patches from Minh Tran-le
5437 <mtranle@paris.intellicorp.com>.
5438 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5439 obj_format coffbfd and gas_target i386coff for target.
5440 (i[34]86-*-isc*): New host (uses sysv).
5441 * config/i386aix.mt: Removed (no longer used).
5442 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5444 (LDFLAGS): Added, defined as -shlib.
5445 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5446 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5447 (DOT_LABEL_PREFIX): Define.
5448 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5449 name rather than L0\001.
5450 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5452 * symbols.c, symbols.h (local_bss_counter): Removed.
5453 * write.c (write_object_file): bss no longer uses

5461 (size_section): Restored sanity check.
5462 (do_relocs_for): Base section address on s_paddr rather than
5463 computing it. Adjust a29k R_IHIHALF special case to account for
5464 section paddr (used to require paddr to be zero). If there are no
5465 reclos, set s_relptr to 0. Set relocation size in object_headers.
5466 (fill_section): Always set s_vaddr here, removing
5467 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5468 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5469 Set STYP_INFO for .comment.
5470 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5471 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5473 H_{SET,GET}_* macros.
5474 (do_linenos_for): Set lineno size in object_headers.
5475 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5476 set s_vaddr here. If string_byte_count remains 4, set it back to
5477 0, and only write strings out if there are some. Call
5478 fill_section before do_relocs_for and do_linenos_for.
5479 (obj_coff_section): Handle optional quoted second argument giving
5480 section characteristics.
5481 (obj_coff_bss): Added to handle .bss.
5482 (obj_coff_ident): Added to handle .ident (puts string in .comment

5502 (do_scrub_next_char): For \", return " not '.
5503 (symbol_chars): Now const.
5505 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5506 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5508 * config/obj-coff.h: Don't use #elif.
5510 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5511 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5513 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5515 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5537 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5538 using ZERO_BASED_SEGMENTS.
5539 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5540 never set segment address for SEG_E2 (.bss) and don't write out
5541 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5542 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5543 definitions, and don't merge tags with non-tags. Check for .bf
5544 rather than just checking whether the second character is b and
5545 the third character is f.
5546 (obj_coff_val): gcc can generate values which we don't handle
5547 correctly; discard information for now, since it only affects the
5548 debugging information.
5549 (tag_find_or_name): Don't insert tags in the symbol table.
5550 (yank_symbols): Don't merge labels.
5551 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5606 options. Updated options documentation for m68k. Some minor
5607 wording/punctuation changes.

5661 xrealloc from xrealloc.c.
5662 * xrealloc.c: Deleted.
5663 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
5665 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
5668 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
5670 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

5689 * all files: Whitespace changes for GNU indentation style, done by
5690 GNU `indent'. Some cleanup still needed, especially of comments.
5692 * configure.in: No te-386bsd.h file exists; don't try to use it.
5694 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
5696 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5697 could be doing emulation.
5699 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5702 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5729 consistently const, and always initialized them. Included read.h.
5731 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5733 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5734 constant will not fit in an immediate field.
5735 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
5737 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
5739 * obj-coff.c (callj_table): Delete global variable.

5770 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5772 * Support for i386-sysv.
5773 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5774 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5775 be used to set them all to zero as was done before.

5777 (fill_section): Don't set STYP_NOLOAD for .bss section.
5778 (fixup_segment): 386 uses strange common symbol format.
5779 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
5780 compatibility with SVR3.2 linker.
5781 * configure.in: i386-sysv and i386-sco use coffbfd.
5783 * app.c (do_scrub_next_char): discard whitespace after a label.

5792 fix i960+non-bfd coff bit rot.
5793 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
5794 support for C source listings. (obj_coff_endef): look in the right

5797 * tc-m68k.c (get_num): make it work for all segments, not just the
5800 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

5811 * tc-z8k.c: lots of bug fixes
5813 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5815 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5816 #elif, since it is not supported by old compilers.
5817 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5818 couple of expressions in tc-m68k.c.
5820 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5822 * read.c (cons): If NO_RELOC is defined, use it.
5824 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5826 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5828 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5829 local labels to start with a .) and set REGISTER_PREFIX to %.
5830 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5832 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5846 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5848 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5849 sections starting from zero, rather than making them consecutive.
5850 This makes subsequent reloc calculations easier, esp if the object
5851 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5852 allocate lcomm in .data rather than in .bss. It seems that some
5853 tools can't cope with a non-zero sized bss before linkage.
5855 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5857 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5858 throughout. That enum no longer means what we thought it meant.

5861 "-mno-688[58]1" options.
5863 * tc-m68k.c: Added CPU32 support.

5872 Change LIBDEPS dependence to LIBS.
5874 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5876 * Makefile.in (install): if $(tooldir) exists, install as in
5879 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5881 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5882 .word is < -32768 or > 32767. The -J flag causes the error to be
5883 ignored. This is to catch over-sized switches generated by gcc on
5884 systems which don't support the broken .word hack.
5885 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5886 write.c (fixup_segment): check for signed .word overflow if
5887 WARN_SIGNED_OVERFLOW_WORD.
5889 * write.c (fixup_segment): fixed missing parens in expression
5890 checking for byte or word overflow.
5892 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
5893 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
5894 WARN_SIGNED_OVERFLOW_WORD.

5906 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5908 * input-scrub.c (input_scrub_push): call input_file_begin, not
5910 messages.c (as_perror): print ": " between the passed in error and
5911 the strerror, like perror does.
5913 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5915 * Makefile.in: use gas_target instead of modifying target_cpu.
5916 From Steve Chamberlain:
5917 Makefile.in: Handle m68*-*-coff*.
5918 read.c, read.h: add mult argument to s_space
5920 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5921 Motorola and MIT syntax; gas can now assemble either type of
5923 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
5924 From Steve Chamberlain:
5925 m68kcoff.mt: for m68k COFF.
5926 obj-coffbfd.c: (fixup_mdeps) added

5929 (write_object_file) call fixup_mdeps
5930 (fixup_segment) set fx_subsy to 0.
5931 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5933 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5936 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5938 * Makefile.in (LIBS): Include opcode library.
5940 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
5942 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

5960 tc-i960.c (md_ri_to_chars): Always output bout object file in
5961 little endian byte order (used to use endianness of host).
5963 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5965 * config/tc-m68k.c (init_table): Now const. Always include 68851
5966 data, so that "bc" is available to 68040 cache instructions.
5967 Added "tt0", "tt1", and 68ec030 variants.
5968 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5969 (enum _register): Added TT0, TT1.
5970 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5971 line number correctly in "internal error" messages. Don't print
5972 architecture-mismatch message for operand errors.
5974 From Colin Smith (colin@wrs.com):
5975 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5976 than install_operand.

5980 * listing.c (buffer_line): rewind to the start of include
5981 files, they might be included twice.

5988 one element of a family.
5990 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5992 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5993 so that we can assemble hand-written libgcc code.
5995 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5997 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5998 has already been formatted (but may still contain %-characters).
6001 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6003 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6004 written with indirection on the last two operands, which can be
6005 either data or address registers. Added a new operand type 'r'
6006 which accepts either register type. Added '(' to notend stuff in
6007 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6009 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
6011 * as.h (enum _relax_state): Start off at one, not zero, to better

6020 data_last_frag): No longer static.
6021 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
6022 defined, call it. Change segments before calling fixup_segment.
6023 (relax_align): If linkrelax, provide extra padding.
6025 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6026 their not having symbols associated.
6028 * tc-i960.c (norelax, instrument_branches): Default initializer is
6030 (linkrelax): Delete variable definition.

6051 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6053 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
6054 being used with args swapped, causing occasional lossage when
6055 refilling buffers after an include file.
6057 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
6059 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6060 version. Discard bogus DONTDEF version.
6061 (as_warn, as_bad, as_fatal): Likewise.
6063 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6065 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6066 selected architecture, print a message saying so and listing what
6067 processors support it, rather than saying "operands mismatch".

6084 if TN_SUN3; otherwise align to 2**N-byte bounary.
6086 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6088 * read.c (s_fill): make the .fill size clamped error a warn and
6089 fix bug where 0's were always placed.
6091 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
6092 two bytes of any constant with 0xff:
6094 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6096 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
6097 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

6106 * config/tc-sparc.c (tc_aout_fix_to_chars): If pc-relative, take
6107 fx_offset into account.
6109 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
6111 * configure.in (mips host): Accept "ultrix" with version number.
6113 * expr.c (floating_constant): Separate "=-" to avoid confusing
6114 ancient or broken compilers.
6116 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6117 processor/opcode mismatch, so reword the error message.
6118 (md_assemble): If no CPU has been set (even if FPU/PMMU
6119 characteristics have been), default to 68020. Don't need extra
6120 quotes around error string.
6122 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
6124 * read.c (potable): Revert sac's incorrect change made Jul 13.

6204 * write.c (write_object_file): keep the fix_tail clean, which
6205 fixes a bug in -R where relocations were being lost.

6256 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6258 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6259 where gcc looks for it.
6261 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6263 * Makefile.in: Changed some lines to be less confusing for some

6329 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6331 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6333 * expr.c (operand): if can't work out what sort of operand it is,
6334 then look through FLT_CHARS for a hint.
6336 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6338 * Makefile.in, configure.in: removed traces of namesubdir,

6340 copyrights to '92, changed some from Cygnus to FSF.
6342 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6343 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6344 copyrights to '92, changed some from Cygnus to FSF.
6346 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6348 * expr.c: If an expression is single comma, then return with
6349 SEG_ABSENT rather than an error - since the sparc front end does
6350 really strange things with things like fbge,a
6352 * as.h: include bfd.h if using many sections
6353 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6354 local labels didn't work.
6355 * listing.c (list_symbol_table): don't core dump when there's no
6357 * write.c, write.h: call fix_new with the right number of args on
6359 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6362 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6364 * app.c: MRI compatibility - allow single quote to start a string.
6365 * as.c: fix typo recently introduced.
6366 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6367 * expr.c: Much rewriting, to accomodate MRI syntax for
6368 expressions. Also easier to read now.
6369 * listing.c: Put back defuns
6370 * read.c: modified to accept MRI syntax, put back listing pseudo
6371 ops so that an assembler built with NO_LISTING ignores list ops
6373 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6374 machine is a SPARC or a 29K.
6375 * config/obj-aout.c: added s_sect pseudo op
6376 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6377 fill in the timestamp.
6378 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6379 anymore, define all the relocs which the tc-<x> bit will use so we
6380 can translate from them to the coff types.
6381 * config/tc-a29k.c: reloc_type isn't ane enum any more
6382 * config/tc-m68k.c: Added NO_RELOC definition.
6384 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6386 * Makefile.in: put header files before C source for TAGS; remove
6387 references to non-existent syscalls.h.
6389 * read.c, write.c subsegs.c: back out the .bss changes.
6391 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6393 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6397 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6399 * symbols.c (local_label_name): symbols now start with ^A.
6401 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6402 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6403 generate these sections. .align: will use NOP_OPCODE or 0
6404 for padding. This is just for being nice to the
6407 * expr.c (operand): changed to generate local label "\001L0"
6408 starting with a ^A so that it is recognized as a local label.
6410 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6412 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6413 i/o opcodes - inb, inw, outb and outw. string manipulation with
6414 att syntax - scmp, slod, smov, ssca, ssto.
6416 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6417 to just after .file .
6419 In obj_crawl_symbol_chain() where it tries to put the external
6420 symbols apart, with the condition:
6421 (!S_IS_DEFINED(symbolP) &&
6422 !S_IS_DEBUG(symbolP) &&
6423 !SF_GET_STATICS(symbolP))
6424 it was moving too many symbols out. So I switch it back to the
6426 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6428 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6429 so that we don't use the F_RELFLG which make the linker complain
6430 that somebody has stripped the relocation info.
6432 Also, the AIX ld program require that the relocation table
6433 is sorted by r_vaddr like the standard ATT assembler does.
6435 [he also changed the sizeof(struct ...)'s into the coff
6436 style FOOSZ macros. I'm not sure this is right, but I can't
6437 remember why. xoxorich.]
6439 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6441 * Makefile.in, configure.in, doc: use the doc. Build it, install
6444 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6446 * read.c: white space and comments only.
6448 * configure.in: use the new atof-ns32.c for ns32k.
6450 * write.c: comment change only.
6452 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6453 aren't yet integrated.
6455 * tc-i860.[hc]: blew off the dust. Something must still be done
6456 about conflicting relocation types.
6458 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6461 * tc-i960.c, tc-sparc.c: white space and comments only.
6463 * tc-a29k.h: delete duplicate macro definition.
6465 * new file atof-ns32k.c copied from hack's last unreleased gas.
6467 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6469 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6472 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6473 ChangeLog's prior to this are sketchy at best. I have logs.
6474 They just aren't ChangeLogs.
6478 version-control: never
