14 * write.c (symbol_table_frozen): New variable, to be set after
15 bfd_set_symtab is called.
16 (dump_section_relocs): Note whether a symbol is a section symbol
18 (adjust_reloc_syms): For now, always supply an absolute symbol for
19 fixups without symbols but not yet `done'. Use section_symbol to
20 get the symbol, instead of going directly for abs_symbol.
21 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
22 reloc is not a section symbol and is not in the symbol table.
23 (set_symtab): New function, broken out from write_object_file.
24 Counts symbol table instead of relying on an earlier count.
25 (write_object_file): Call set_symtab, but do it after potentially
26 invoking the *_frob_file macros. Don't bother counting symbols.
27 Call symbol_remove, instead of expanding it in place. Moved the
28 conditionalized `object_file_size' declaration down to
29 conditionalized block where it's used. When using the absolute
30 symbol for a fixup without a symbol, set sy_used_in_reloc.
31 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
32 the correct symbol for the absolute section.
34 * subsegs.c (section_symbol): Use symbol_new instead of
35 symbol_make, since we may want it to go into the symbol table.
36 Make the new symbol have internal linkage. If
37 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
38 symbol with the newly created GAS symbol.
39 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
40 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

45 (in_signed_range): New function.
47 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
48 (sparc_ip, label "immediate"): Reject constants for pcrel
49 instructions only if the relocation type indicates a "call"
50 instruction and the offset is within range of a "jmpl %g0". If
51 it's not in range, use the absolute section symbol plus an offset.
52 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
54 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
56 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
59 * configure.in: Eliminated all targets using obj-coff but not
60 defining BFD_ASSEMBLER; I think all such targets that are
61 supported will be matched by real CPU-OS combinations earlier in
63 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
64 some comments about the dpx2 configuration, but left it disabled,
65 since it couldn't be reached before.

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

104 version number. Delete all versions of temp files when finished
105 with them. Create config.h.
107 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
108 values to reduce number of lookups with S_GET_VALUE. Skip debug
109 symbols to avoid "a really nasty bug". (From Holger Teutsch,
110 holger@botbso.rhein-main.de.)
111 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
112 field. (Also from Holger Teutsch.) Watch for a would-be register
113 mask that spans frags.
115 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
116 this_base, not line_base. (Patch from Andreas Arens,
117 ari@obelix.av.rwth-aachen.de.)
119 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
120 look local if they're exported or undefined. Used to be done for
123 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

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

1908 BFD_RELOC_MIPS_GPREL. Added new case a.
1909 (set_at, load_register, macro): Changed calls to macro_build to
1910 pass new argument for i, j and o cases.
1911 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1912 special handling when generating SVR4 PIC code.

2188 * write.c (write_relocs): For relocs that are pc_relative and
2189 pcrel_offset and not partial_inplace, adjust reloc->addend to

2245 for keeping or rejecting configurations still under development;
2246 default is to assume production environment, and reject configs
2247 still being worked on. Mark Elf configurations (except sparc and
2248 i386) as developmental. Deleted cases matching some generic names
2249 in favor of more specific names. (E.g., when we get Alpha

2266 through inclusion of tc-hppa.h. Delete all forward declarations
2267 for functions only used within tc-hppa.c, likewise for structures,
2268 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2269 conditional code in a few small places.
2271 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group

2274 conditional code -- try to group conditional code together
2275 into a few places. Make all functions and variables which
2276 are only used within tc-hppa.c static. PARAMize all functions.
2277 Add comments to functions. Delete unused functions, variables,
2278 #defines, etc. Delete unused members within structures. Delete
2279 ldil;ble hacks -- it is believed they were installed to work
2280 around old gas bugs. Avoid using mixed case for local
2281 functions, variables, and structures. Fix formatting problems
2282 not found by GNU-indent. Add FIXME notices for things which
2283 should be worked on the near future. Delete lots of old
2284 useless (1.36 PA-SOM) code.

2316 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2317 bits are zero (eg they specify no relocations), then do not even
2318 bother adding their entries to thesymextn section.

2357 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2359 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2360 ELF, since the ELF object format does not have these type of
2361 relocations. Change the abort into as as_bad and return
2362 BFD_RELOC_NONE to silence compiler warnings.
2363 (md_assemble): Keep track of the instruction size. Allow white
2364 space between the $ and the constant for compatibility with older
2365 gases and other assemblers.
2366 (i386_operand): Skip spaces between $ and expression.
2367 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

3313 Thu Jul 29 18:38:37 1993 david d `zoo' zuhn (zoo@rtl.cygnus.com)
3315 * config/ho-sunos.h: remove some old function decls that conflict
3316 w/ ANSI, and which weren't needed anyway
3318 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3320 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

3427 * Extensive changes to permit symbols to contain any expression
3428 type and to delay the computation of the expression until the
3429 value is actually needed. This permits setting symbols to values
3430 calculated based on object code size. Expressions were changed to
3431 no longer be in a section, to stop the overloading of segment and
3432 expression type that previously occurred.
3434 * as.c (big_section, pass1_section, diff_section, absent_section):
3436 (expr_section): Added (used for dummy symbols which hold

4702 dependencies are read, not when they are used).
4704 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
4705 a29k .bss section; the mondfe program doesn't like it.

4754 avoid some redefinition complaints on some systems.
4755 (const, volatile): Don't need these conditionally defined if we
4756 use CONST and VOLATILE from ansidecl.h.
4757 (seg_name): Use CONST, not const.
4759 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4761 * config/tc-mips.c: Reindented to GNU standards.

4794 * Makefile.in (targ-cpu.o): Depend on config.h.
4796 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4798 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4799 dropping a space immediately following an identifier.
4800 * expr.c, write.c: Rewrote assert expressions to not use multiple
4801 lines; I don't think that can be done portably.
4802 * config/tc-mips.c (macro): Use $AT if target register is zero in
4803 load instruction, which it can be for a floating point load.
4805 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4826 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4828 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4829 to be on a single line.

4877 prototypes for all static functions. Moved existing minimal
4878 debugging format support info #ifndef OBJ_ECOFF blocks.

4927 * make-gas.com: Find obstack.obj if it's not in the current
4929 * read.c (s_ignore): Don't declare is_end_of_line. It's
4930 redundant, and triggers a VMS gcc compiler bug.
4932 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4933 current segment as an argument. (Ignored in all cases but VMS.)
4934 All callers and definitions changed.

5230 * config/tc-sparc.c (architecture_requested, warn_on_bump,
5231 md_relax_table): Use default zero initialization.
5232 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5233 latter, instead of selecting with preprocessor conditionals.
5235 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5237 * configure.in: recognise all sparclite variants
5239 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5245 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
5247 * expr.c (operand): If character other than comma or newline is a
5248 logical end-of-line character, use the newline case.
5249 From Eric Youngdale:
5250 (operand): Set X_add_number field for floating-point numbers.
5251 (operand): Treat zero byte as end-of-operand.
5253 * configure.in (per-target): Look for with_bfd_assembler option.
5254 For now, only accept "no", until the merge is done.
5256 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5257 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
5258 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
5259 * read.c: Finish conversion to S_* macros in the VMS only
5260 parts of the program. Add "const" modifier to hex_value.
5261 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
5263 * expr.c: Add "const" modifier to hex_value.
5264 * symbols.c: Finish conversion to S_* macros in the VMS only
5265 parts of the program. Add "const" modifier to
5266 md_[long,short]_jump_size. Remove declaration of const_flag
5267 (which will be declared in obj-vms.h).
5268 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5269 Fix arguments to VMS_write_object_file.
5270 * config-gas.com: New file. Script for VMS systems to set up the
5271 configuration to build gas for VMS, and create config.status.
5272 * make-gas.com: Redone to work with new scheme.
5273 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5275 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5276 will swap bytes if needed on a big endian system. Use throughout
5278 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5279 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5280 types of malformed stabs. Change parsing algorithm so that we are
5281 more certain of having all of the information that we need on hand.
5282 * obj-vms.c (final_forward_reference): New function, used to help
5283 resolve the data types of as many struct elements as possible
5284 when some part of the struct is not fully defined by the compiler.
5285 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5287 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5288 as symbols as well in the object file. Look for external functions
5289 that start with "__vt.", and turn them into variables, since the
5290 g++ compiler is incapable of doing this.
5291 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5293 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5294 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5295 have the name of the source file yet.
5296 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5298 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5300 * read.c (s_data): Always use "data_section", since it'll map to
5301 SEG_DATA or SEG_E1 if needed.
5302 (s_lcomm): Likewise with bss_section.
5303 (s_fill): Use memset, not bzero.
5305 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5326 (section_alignment): Declare only if not BFD_ASSEMBLER.
5327 (big_section, reg_section, pass1_section, diff_section,
5328 absent_section, text_section, data_section, bss_section): If
5329 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5330 mapping to segT enum values.
5331 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5332 if these are used or defined, if BFD_ASSEMBLER.
5333 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5334 subseg_new split into two functions.
5335 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5337 * as.h (volatile): Don't define if already defined.
5338 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5340 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5341 declare with format attribute for -Wformat checking.
5343 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5345 * app.c, config/tc-*.c: Don't include read.h, since it is already
5348 * These are based on patches from Minh Tran-le
5349 <mtranle@paris.intellicorp.com>.
5350 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5351 obj_format coffbfd and gas_target i386coff for target.
5352 (i[34]86-*-isc*): New host (uses sysv).
5353 * config/i386aix.mt: Removed (no longer used).
5354 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5356 (LDFLAGS): Added, defined as -shlib.
5357 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5358 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5359 (DOT_LABEL_PREFIX): Define.
5360 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5361 name rather than L0\001.
5362 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5364 * symbols.c, symbols.h (local_bss_counter): Removed.
5365 * write.c (write_object_file): bss no longer uses
5366 local_bss_counter. Pass correct data and bss size to

5373 (size_section): Restored sanity check.
5374 (do_relocs_for): Base section address on s_paddr rather than
5375 computing it. Adjust a29k R_IHIHALF special case to account for
5376 section paddr (used to require paddr to be zero). If there are no
5377 reclos, set s_relptr to 0. Set relocation size in object_headers.
5378 (fill_section): Always set s_vaddr here, removing
5379 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5380 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5381 Set STYP_INFO for .comment.

5385 H_{SET,GET}_* macros.
5386 (do_linenos_for): Set lineno size in object_headers.
5387 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5388 set s_vaddr here. If string_byte_count remains 4, set it back to
5389 0, and only write strings out if there are some. Call
5390 fill_section before do_relocs_for and do_linenos_for.
5391 (obj_coff_section): Handle optional quoted second argument giving
5392 section characteristics.
5393 (obj_coff_bss): Added to handle .bss.
5394 (obj_coff_ident): Added to handle .ident (puts string in .comment

5414 (do_scrub_next_char): For \", return " not '.
5415 (symbol_chars): Now const.
5417 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5418 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5420 * config/obj-coff.h: Don't use #elif.
5422 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5423 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5449 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5450 using ZERO_BASED_SEGMENTS.
5451 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5452 never set segment address for SEG_E2 (.bss) and don't write out
5453 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5454 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5455 definitions, and don't merge tags with non-tags. Check for .bf
5456 rather than just checking whether the second character is b and
5457 the third character is f.
5458 (obj_coff_val): gcc can generate values which we don't handle
5459 correctly; discard information for now, since it only affects the
5460 debugging information.
5461 (tag_find_or_name): Don't insert tags in the symbol table.
5462 (yank_symbols): Don't merge labels.
5463 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5666 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
5667 so widening works consistently.
5669 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
5671 * version.c: Put conditional "const" before version_string, not
5672 before dummy function for VMS. Now version 1.91.03.
5674 * app.c (do_scrub_next_char): Need double-\ before `000' to show
5675 printed rep of null character.
5677 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
5679 * obj-coffbfd.c (write_object_file): check return value of
5682 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5684 * Support for i386-sysv.
5685 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5686 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5687 be used to set them all to zero as was done before.
5688 (fill_section): segment addresses now set in write_object_file.
5689 (fill_section): Don't set STYP_NOLOAD for .bss section.
5690 (fixup_segment): 386 uses strange common symbol format.
5691 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
5692 compatibility with SVR3.2 linker.
5693 * configure.in: i386-sysv and i386-sco use coffbfd.

5704 fix i960+non-bfd coff bit rot.
5705 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
5706 support for C source listings. (obj_coff_endef): look in the right
5707 part of the symbol for the symbol name
5709 * tc-m68k.c (get_num): make it work for all segments, not just the
5712 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5714 * configure.in: recognize i386-*-bsd emulation.

5723 * tc-z8k.c: lots of bug fixes
5725 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5727 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5728 #elif, since it is not supported by old compilers.
5729 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5730 couple of expressions in tc-m68k.c.
5732 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5734 * read.c (cons): If NO_RELOC is defined, use it.
5736 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5738 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5740 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5741 local labels to start with a .) and set REGISTER_PREFIX to %.
5742 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5760 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5761 sections starting from zero, rather than making them consecutive.
5762 This makes subsequent reloc calculations easier, esp if the object
5763 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5764 allocate lcomm in .data rather than in .bss. It seems that some
5765 tools can't cope with a non-zero sized bss before linkage.
5767 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5769 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5788 * Makefile.in (install): if $(tooldir) exists, install as in
5791 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5793 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5794 .word is < -32768 or > 32767. The -J flag causes the error to be
5795 ignored. This is to catch over-sized switches generated by gcc on
5796 systems which don't support the broken .word hack.
5797 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5798 write.c (fixup_segment): check for signed .word overflow if
5799 WARN_SIGNED_OVERFLOW_WORD.
5801 * write.c (fixup_segment): fixed missing parens in expression
5802 checking for byte or word overflow.

5818 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5820 * input-scrub.c (input_scrub_push): call input_file_begin, not
5822 messages.c (as_perror): print ": " between the passed in error and
5823 the strerror, like perror does.
5825 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

5828 From Steve Chamberlain:
5829 Makefile.in: Handle m68*-*-coff*.
5830 read.c, read.h: add mult argument to s_space
5832 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5833 Motorola and MIT syntax; gas can now assemble either type of
5835 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5842 (fixup_segment) set fx_subsy to 0.
5843 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5845 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5848 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5850 * Makefile.in (LIBS): Include opcode library.

5875 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5877 * config/tc-m68k.c (init_table): Now const. Always include 68851
5878 data, so that "bc" is available to 68040 cache instructions.
5879 Added "tt0", "tt1", and 68ec030 variants.
5880 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5881 (enum _register): Added TT0, TT1.
5882 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5883 line number correctly in "internal error" messages. Don't print
5884 architecture-mismatch message for operand errors.
5886 From Colin Smith (colin@wrs.com):
5887 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5888 than install_operand.

5909 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5910 has already been formatted (but may still contain %-characters).
5913 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5915 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5916 written with indirection on the last two operands, which can be
5917 either data or address registers. Added a new operand type 'r'
5918 which accepts either register type. Added '(' to notend stuff in
5919 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5938 their not having symbols associated.
5940 * tc-i960.c (norelax, instrument_branches): Default initializer is
5942 (linkrelax): Delete variable definition.

5966 being used with args swapped, causing occasional lossage when
5967 refilling buffers after an include file.

6026 ancient or broken compilers.
6028 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
6029 processor/opcode mismatch, so reword the error message.

6144 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6146 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
6147 calc the base of relocs correctly.
6148 * tc-a29k.c (parse_operand): allow expressions to be in any section.
6150 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
6152 * as.c, write.c: use -K rather than -k for the broken word warning
6155 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
6157 * Makefile.in: do not print recursion lines.
6159 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6161 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
6163 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6165 * write.c (write_object_file): For b.out format, round up section
6166 start addresses to match required alignment.
6168 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6170 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6171 where gcc looks for it.
6173 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6175 * Makefile.in: Changed some lines to be less confusing for some
6178 * input-file.c: Conditionalize on _IOFBF, not VMS.
6180 * read.c, write.c: Change a series of ifdef/elif to
6181 ifdef/else/ifdef etc.
6183 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
6185 * symbols.c (fb_label_init): fix sizeof to memset.
6187 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
6189 * Makefile.in: install the man page.
6191 * Makefile.in: pass down MAKEINFO explicitly on info.
6193 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
6195 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6197 * flonum-const.c: renamed flonum-konst.c to stop dos name
6200 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
6202 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
6203 tc-m68k.h to te-sun3.h.
6205 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
6207 * configure.in: vxworks68 gets te-sun3.h.
6209 * expr.c: remove limitation that local_labels_dollar or
6210 local_labels_fb must be < 10.
6212 * symbols.c: remove local_labels_dollar, replace with a function
6213 interface for a sparse array. All users adjusted.
6215 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
6217 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6219 * doc/Makefile.in: commented out line for building as-all.texinfo.
6222 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
6224 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
6226 * Makefile.in: added check target.
6228 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6230 * Makefile.in: added tooldir and program_prefix.
6232 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
6234 * write.{c,h} (fix_new): Make these declarations consistent.
6236 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
6238 * Makefile.in (strerror.o): Add rule so that broken Sun make can
6241 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6243 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6245 * expr.c (operand): if can't work out what sort of operand it is,
6246 then look through FLT_CHARS for a hint.
6248 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6250 * Makefile.in, configure.in: removed traces of namesubdir,
6251 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6252 copyrights to '92, changed some from Cygnus to FSF.
6254 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6255 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6256 copyrights to '92, changed some from Cygnus to FSF.
6258 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6260 * expr.c: If an expression is single comma, then return with
6261 SEG_ABSENT rather than an error - since the sparc front end does
6262 really strange things with things like fbge,a
6264 * as.h: include bfd.h if using many sections
6265 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6266 local labels didn't work.
6267 * listing.c (list_symbol_table): don't core dump when there's no
6269 * write.c, write.h: call fix_new with the right number of args on
6271 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6274 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6276 * app.c: MRI compatibility - allow single quote to start a string.
6277 * as.c: fix typo recently introduced.
6278 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6279 * expr.c: Much rewriting, to accomodate MRI syntax for
6280 expressions. Also easier to read now.
6281 * listing.c: Put back defuns
6282 * read.c: modified to accept MRI syntax, put back listing pseudo
6283 ops so that an assembler built with NO_LISTING ignores list ops
6285 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6286 machine is a SPARC or a 29K.
6287 * config/obj-aout.c: added s_sect pseudo op
6288 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6289 fill in the timestamp.
6290 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6291 anymore, define all the relocs which the tc-<x> bit will use so we
6292 can translate from them to the coff types.
6293 * config/tc-a29k.c: reloc_type isn't ane enum any more
6294 * config/tc-m68k.c: Added NO_RELOC definition.
6296 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6298 * Makefile.in: put header files before C source for TAGS; remove
6299 references to non-existent syscalls.h.
6301 * read.c, write.c subsegs.c: back out the .bss changes.
6303 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6305 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6309 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6311 * symbols.c (local_label_name): symbols now start with ^A.
6313 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6314 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6315 generate these sections. .align: will use NOP_OPCODE or 0
6316 for padding. This is just for being nice to the
6319 * expr.c (operand): changed to generate local label "\001L0"
6320 starting with a ^A so that it is recognized as a local label.
6322 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6324 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6325 i/o opcodes - inb, inw, outb and outw. string manipulation with
6326 att syntax - scmp, slod, smov, ssca, ssto.
6328 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6329 to just after .file .
6331 In obj_crawl_symbol_chain() where it tries to put the external
6332 symbols apart, with the condition:
6333 (!S_IS_DEFINED(symbolP) &&
6334 !S_IS_DEBUG(symbolP) &&
6335 !SF_GET_STATICS(symbolP))
6336 it was moving too many symbols out. So I switch it back to the
6338 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6340 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6341 so that we don't use the F_RELFLG which make the linker complain
6342 that somebody has stripped the relocation info.
6344 Also, the AIX ld program require that the relocation table
6345 is sorted by r_vaddr like the standard ATT assembler does.
6347 [he also changed the sizeof(struct ...)'s into the coff
6348 style FOOSZ macros. I'm not sure this is right, but I can't
6349 remember why. xoxorich.]
6351 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6353 * Makefile.in, configure.in, doc: use the doc. Build it, install
6356 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6358 * read.c: white space and comments only.
6360 * configure.in: use the new atof-ns32.c for ns32k.
6362 * write.c: comment change only.
6364 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6365 aren't yet integrated.
6367 * tc-i860.[hc]: blew off the dust. Something must still be done
6368 about conflicting relocation types.
6370 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6373 * tc-i960.c, tc-sparc.c: white space and comments only.
6375 * tc-a29k.h: delete duplicate macro definition.
6377 * new file atof-ns32k.c copied from hack's last unreleased gas.
6379 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6381 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6384 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6385 ChangeLog's prior to this are sketchy at best. I have logs.
6386 They just aren't ChangeLogs.
6390 version-control: never
