217 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
219 * Extensive changes to permit symbols to contain any expression
220 type and to delay the computation of the expression until the
221 value is actually needed. This permits setting symbols to values
222 calculated based on object code size. Expressions were changed to

315 section name. Don't crash on invalid strings.
316 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
319 * config/obj-elf.h: Don't include struc-symbol.h.

376 (macro): Call mips_emit_delays before setting mips_noreorder.
377 Increment and decrement mips_noreorder rather than using

428 sy_resolved and sy_resolving single bit fields.
429 * symbols.c (symbol_new): Don't initialize sy_forward field.

452 segment rather than sy_forward.

454 sy_forward; do initialize sy_resolved and sy_resolving.
455 * config/tc-hppa.h (STAB_FIXUP): Use sy_value, not sy_forward.
457 * Changes to keep a full expression as the value of a symbol, not
459 * struc-symbol.h: New field sy_value.

1465 * doc/as.texinfo: First pass at using new texinfo features --
1466 variables, conditional tests. Far from complete.

1494 dependencies are read, not when they are used).
1496 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
1497 a29k .bss section; the mondfe program doesn't like it.

1542 process relocs if there aren't any relocs to process. Avoids
1543 malloc/free bug on SCO too.

1546 avoid some redefinition complaints on some systems.
1547 (const, volatile): Don't need these conditionally defined if we
1548 use CONST and VOLATILE from ansidecl.h.
1549 (seg_name): Use CONST, not const.
1551 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
1553 * config/tc-mips.c: Reindented to GNU standards.

1557 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
1558 (fixup_segment): Add a29k special case; the linker is not prepared
1559 to see a segment offset here.
1561 * app.c (do_scrub_next_char): Added new state, 10, modifying state

1564 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
1566 * Makefile.in: add dvi target; as-$(config).texinfo might live in

1582 bignums, but don't emit error message.
1584 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
1586 * Makefile.in (targ-cpu.o): Depend on config.h.
1588 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
1590 * app.c (do_scrub_next_char): Added new state, 9, to avoid
1591 dropping a space immediately following an identifier.
1592 * expr.c, write.c: Rewrote assert expressions to not use multiple
1593 lines; I don't think that can be done portably.
1594 * config/tc-mips.c (macro): Use $AT if target register is zero in
1595 load instruction, which it can be for a floating point load.
1597 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

1618 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
1620 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
1621 to be on a single line.
1623 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

1669 prototypes for all static functions. Moved existing minimal
1670 debugging format support info #ifndef OBJ_ECOFF blocks.

1674 (tc_get_register): Renamed from get_register, and made non-static.
1676 * config/mips-big.mt, config/mips-lit.mt: New files. Define

1719 * make-gas.com: Find obstack.obj if it's not in the current
1721 * read.c (s_ignore): Don't declare is_end_of_line. It's
1722 redundant, and triggers a VMS gcc compiler bug.
1724 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1725 current segment as an argument. (Ignored in all cases but VMS.)
1726 All callers and definitions changed.

2023 md_relax_table): Use default zero initialization.
2024 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
2025 latter, instead of selecting with preprocessor conditionals.
2027 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
2029 * configure.in: recognise all sparclite variants

2039 * expr.c (operand): If character other than comma or newline is a
2040 logical end-of-line character, use the newline case.
2041 From Eric Youngdale:
2042 (operand): Set X_add_number field for floating-point numbers.
2043 (operand): Treat zero byte as end-of-operand.
2045 * configure.in (per-target): Look for with_bfd_assembler option.
2046 For now, only accept "no", until the merge is done.
2048 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
2049 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

2055 * expr.c: Add "const" modifier to hex_value.
2056 * symbols.c: Finish conversion to S_* macros in the VMS only
2057 parts of the program. Add "const" modifier to
2058 md_[long,short]_jump_size. Remove declaration of const_flag
2059 (which will be declared in obj-vms.h).
2060 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2061 Fix arguments to VMS_write_object_file.
2062 * config-gas.com: New file. Script for VMS systems to set up the
2063 configuration to build gas for VMS, and create config.status.
2064 * make-gas.com: Redone to work with new scheme.
2065 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2067 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2068 will swap bytes if needed on a big endian system. Use throughout
2070 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2071 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2072 types of malformed stabs. Change parsing algorithm so that we are
2073 more certain of having all of the information that we need on hand.
2074 * obj-vms.c (final_forward_reference): New function, used to help
2075 resolve the data types of as many struct elements as possible
2076 when some part of the struct is not fully defined by the compiler.

2079 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2080 as symbols as well in the object file. Look for external functions
2081 that start with "__vt.", and turn them into variables, since the
2082 g++ compiler is incapable of doing this.
2083 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2085 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2086 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2087 have the name of the source file yet.
2088 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2090 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2092 * read.c (s_data): Always use "data_section", since it'll map to
2093 SEG_DATA or SEG_E1 if needed.
2094 (s_lcomm): Likewise with bss_section.
2095 (s_fill): Use memset, not bzero.
2097 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2119 (big_section, reg_section, pass1_section, diff_section,
2120 absent_section, text_section, data_section, bss_section): If
2121 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2122 mapping to segT enum values.
2123 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2124 if these are used or defined, if BFD_ASSEMBLER.
2125 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2126 subseg_new split into two functions.
2127 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2129 * as.h (volatile): Don't define if already defined.
2130 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2132 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2133 declare with format attribute for -Wformat checking.
2135 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2137 * app.c, config/tc-*.c: Don't include read.h, since it is already
2140 * These are based on patches from Minh Tran-le
2141 <mtranle@paris.intellicorp.com>.
2142 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2143 obj_format coffbfd and gas_target i386coff for target.
2144 (i[34]86-*-isc*): New host (uses sysv).
2145 * config/i386aix.mt: Removed (no longer used).
2146 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2148 (LDFLAGS): Added, defined as -shlib.
2149 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2150 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2151 (DOT_LABEL_PREFIX): Define.
2152 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2153 name rather than L0\001.

2165 (size_section): Restored sanity check.
2166 (do_relocs_for): Base section address on s_paddr rather than
2167 computing it. Adjust a29k R_IHIHALF special case to account for
2168 section paddr (used to require paddr to be zero). If there are no
2169 reclos, set s_relptr to 0. Set relocation size in object_headers.
2170 (fill_section): Always set s_vaddr here, removing
2171 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2172 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2173 Set STYP_INFO for .comment.

2177 H_{SET,GET}_* macros.
2178 (do_linenos_for): Set lineno size in object_headers.
2179 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2180 set s_vaddr here. If string_byte_count remains 4, set it back to
2181 0, and only write strings out if there are some. Call
2182 fill_section before do_relocs_for and do_linenos_for.
2183 (obj_coff_section): Handle optional quoted second argument giving
2184 section characteristics.
2185 (obj_coff_bss): Added to handle .bss.
2186 (obj_coff_ident): Added to handle .ident (puts string in .comment

2206 (do_scrub_next_char): For \", return " not '.
2207 (symbol_chars): Now const.
2209 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2210 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2212 * config/obj-coff.h: Don't use #elif.
2214 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2215 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2241 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
2242 using ZERO_BASED_SEGMENTS.
2243 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2244 never set segment address for SEG_E2 (.bss) and don't write out
2245 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2246 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2247 definitions, and don't merge tags with non-tags. Check for .bf
2248 rather than just checking whether the second character is b and
2249 the third character is f.
2250 (obj_coff_val): gcc can generate values which we don't handle
2251 correctly; discard information for now, since it only affects the
2252 debugging information.

2254 (yank_symbols): Don't merge labels.
2255 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2433 consistently const, and always initialized them. Included read.h.
2435 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2437 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2438 constant will not fit in an immediate field.
2439 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
2441 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

2466 * app.c (do_scrub_next_char): Need double-\ before `000' to show
2467 printed rep of null character.
2469 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
2471 * obj-coffbfd.c (write_object_file): check return value of
2474 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2476 * Support for i386-sysv.
2477 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
2478 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
2479 be used to set them all to zero as was done before.

2481 (fill_section): Don't set STYP_NOLOAD for .bss section.
2482 (fixup_segment): 386 uses strange common symbol format.

2515 * tc-z8k.c: lots of bug fixes
2517 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2519 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2520 #elif, since it is not supported by old compilers.
2521 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2522 couple of expressions in tc-m68k.c.
2524 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2526 * read.c (cons): If NO_RELOC is defined, use it.
2528 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2530 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2532 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2533 local labels to start with a .) and set REGISTER_PREFIX to %.
2534 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

2552 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2553 sections starting from zero, rather than making them consecutive.
2554 This makes subsequent reloc calculations easier, esp if the object
2555 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2556 allocate lcomm in .data rather than in .bss. It seems that some
2557 tools can't cope with a non-zero sized bss before linkage.
2559 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2561 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

2580 * Makefile.in (install): if $(tooldir) exists, install as in
2583 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2585 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2586 .word is < -32768 or > 32767. The -J flag causes the error to be
2587 ignored. This is to catch over-sized switches generated by gcc on
2588 systems which don't support the broken .word hack.
2589 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2590 write.c (fixup_segment): check for signed .word overflow if
2591 WARN_SIGNED_OVERFLOW_WORD.
2593 * write.c (fixup_segment): fixed missing parens in expression
2594 checking for byte or word overflow.

2610 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2612 * input-scrub.c (input_scrub_push): call input_file_begin, not
2614 messages.c (as_perror): print ": " between the passed in error and
2615 the strerror, like perror does.
2617 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

2620 From Steve Chamberlain:
2621 Makefile.in: Handle m68*-*-coff*.
2622 read.c, read.h: add mult argument to s_space
2624 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2625 Motorola and MIT syntax; gas can now assemble either type of
2627 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2634 (fixup_segment) set fx_subsy to 0.
2635 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2637 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2640 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2642 * Makefile.in (LIBS): Include opcode library.

2665 little endian byte order (used to use endianness of host).
2667 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2669 * config/tc-m68k.c (init_table): Now const. Always include 68851
2670 data, so that "bc" is available to 68040 cache instructions.
2671 Added "tt0", "tt1", and 68ec030 variants.
2672 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2673 (enum _register): Added TT0, TT1.
2674 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2675 line number correctly in "internal error" messages. Don't print
2676 architecture-mismatch message for operand errors.
2678 From Colin Smith (colin@wrs.com):
2679 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
2680 than install_operand.

2701 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2702 has already been formatted (but may still contain %-characters).
2705 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2707 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2708 written with indirection on the last two operands, which can be
2709 either data or address registers. Added a new operand type 'r'
2710 which accepts either register type. Added '(' to notend stuff in
2711 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2730 their not having symbols associated.
2732 * tc-i960.c (norelax, instrument_branches): Default initializer is

2758 being used with args swapped, causing occasional lossage when
2759 refilling buffers after an include file.

2817 * expr.c (floating_constant): Separate "=-" to avoid confusing
2818 ancient or broken compilers.
2820 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
2821 processor/opcode mismatch, so reword the error message.
2822 (md_assemble): If no CPU has been set (even if FPU/PMMU
2823 characteristics have been), default to 68020. Don't need extra
2824 quotes around error string.

2882 * write.c (write_object_file): various changes to handle data in
2883 the BSS segment in much the same was as stuff in the DATA segment.

2960 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
2962 * Makefile.in (install): Install into $(tooldir)/bin, since that's

3040 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3042 * Makefile.in, configure.in: removed traces of namesubdir,

3048 copyrights to '92, changed some from Cygnus to FSF.
3050 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3052 * expr.c: If an expression is single comma, then return with
3053 SEG_ABSENT rather than an error - since the sparc front end does
3054 really strange things with things like fbge,a
3056 * as.h: include bfd.h if using many sections
3057 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3058 local labels didn't work.
3059 * listing.c (list_symbol_table): don't core dump when there's no
3061 * write.c, write.h: call fix_new with the right number of args on
3063 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3066 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3068 * app.c: MRI compatibility - allow single quote to start a string.
3069 * as.c: fix typo recently introduced.
3070 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3071 * expr.c: Much rewriting, to accomodate MRI syntax for
3072 expressions. Also easier to read now.
3073 * listing.c: Put back defuns
3074 * read.c: modified to accept MRI syntax, put back listing pseudo
3075 ops so that an assembler built with NO_LISTING ignores list ops
3077 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3078 machine is a SPARC or a 29K.
3079 * config/obj-aout.c: added s_sect pseudo op
3080 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3081 fill in the timestamp.
3082 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3083 anymore, define all the relocs which the tc-<x> bit will use so we
3084 can translate from them to the coff types.
3085 * config/tc-a29k.c: reloc_type isn't ane enum any more
3086 * config/tc-m68k.c: Added NO_RELOC definition.
3088 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3090 * Makefile.in: put header files before C source for TAGS; remove
3091 references to non-existent syscalls.h.
3093 * read.c, write.c subsegs.c: back out the .bss changes.
3095 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3097 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3101 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3103 * symbols.c (local_label_name): symbols now start with ^A.
3105 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3106 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3107 generate these sections. .align: will use NOP_OPCODE or 0
3108 for padding. This is just for being nice to the
3111 * expr.c (operand): changed to generate local label "\001L0"
3112 starting with a ^A so that it is recognized as a local label.
3114 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3116 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3117 i/o opcodes - inb, inw, outb and outw. string manipulation with
3118 att syntax - scmp, slod, smov, ssca, ssto.
3120 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3121 to just after .file .
3123 In obj_crawl_symbol_chain() where it tries to put the external
3124 symbols apart, with the condition:
3125 (!S_IS_DEFINED(symbolP) &&
3126 !S_IS_DEBUG(symbolP) &&
3127 !SF_GET_STATICS(symbolP))
3128 it was moving too many symbols out. So I switch it back to the
3130 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3132 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3133 so that we don't use the F_RELFLG which make the linker complain
3134 that somebody has stripped the relocation info.
3136 Also, the AIX ld program require that the relocation table
3137 is sorted by r_vaddr like the standard ATT assembler does.
3139 [he also changed the sizeof(struct ...)'s into the coff
3140 style FOOSZ macros. I'm not sure this is right, but I can't
3141 remember why. xoxorich.]
3143 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3145 * Makefile.in, configure.in, doc: use the doc. Build it, install
3148 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3150 * read.c: white space and comments only.
3152 * configure.in: use the new atof-ns32.c for ns32k.
3154 * write.c: comment change only.
3156 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3157 aren't yet integrated.
3159 * tc-i860.[hc]: blew off the dust. Something must still be done
3160 about conflicting relocation types.
3162 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3165 * tc-i960.c, tc-sparc.c: white space and comments only.
3167 * tc-a29k.h: delete duplicate macro definition.
3169 * new file atof-ns32k.c copied from hack's last unreleased gas.
3171 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3173 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3176 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3177 ChangeLog's prior to this are sketchy at best. I have logs.
3178 They just aren't ChangeLogs.
