3 * config/tc-mips.c (mips_optimize): New static variable.
4 (append_insn): If mips_optimize == 0, always insert NOP
5 instructions. If mips_optimize < 2, don't swap branches.

25 are also magic, and have special default flag settings.
26 (obj_elf_frob_symbol): Since the return value from this function
27 isn't used, don't bother calling obj_elf_write_symbol_p, since it
28 doesn't accomplish anything else.

84 r_offset field of the reloc to the fixup offset.
85 (fixup_segments): If TC_M88K, don't warn about fixup overflows.
86 * doc/as.texinfo: Minor updates.
88 Tue Jul 20 19:28:56 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
90 * Extensive changes to permit symbols to contain any expression
91 type and to delay the computation of the expression until the
92 value is actually needed. This permits setting symbols to values
93 calculated based on object code size. Expressions were changed to
94 no longer be in a section, to stop the overloading of segment and
95 expression type that previously occurred.

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

226 * read.c (float_cons): Simplified parsing logic. If
227 REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count.
229 * symbols.c (colon): Rather than a special case for TC_HPPA,

247 (macro): Call mips_emit_delays before setting mips_noreorder.
248 Increment and decrement mips_noreorder rather than using
249 save_reorder_condition. Don't bother to use noreorder in

1435 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
1437 * Makefile.in: add dvi target; as-$(config).texinfo might live in
1438 srcdir, might be in objdir.

1462 dropping a space immediately following an identifier.

1465 * config/tc-mips.c (macro): Use $AT if target register is zero in
1466 load instruction, which it can be for a floating point load.

1953 g++ compiler is incapable of doing this.
1954 * tc-vax.c: Add '1' option for backward compatibility with older GCC
1956 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
1957 * input-scrub.c (as_where): Fix bug where as would crash if we did not
1958 have the name of the source file yet.
1959 * config/ho-vms.h: define HO_VMS, not HO_VAX.
1961 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
1963 * read.c (s_data): Always use "data_section", since it'll map to
1964 SEG_DATA or SEG_E1 if needed.
1965 (s_lcomm): Likewise with bss_section.
1966 (s_fill): Use memset, not bzero.
1968 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1970 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

1977 * config/obj-coff.h (segment_name): Ditto.
1978 * config/obj-coffbfd.h (segment_name): Ditto.
1980 * Changes for BFD_ASSEMBLER:
1981 * obj.h (obj_crawl_symbol_chain): Declare only if not
1983 (obj_header_append, obj_pre_write_hook): Ditto.
1984 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
1985 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
1986 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
1987 otherwise, use seg_name array.
1988 (seg_name): Declare only if not BFD_ASSEMBLER.
1989 (section_alignment): Declare only if not BFD_ASSEMBLER.
1990 (big_section, reg_section, pass1_section, diff_section,
1991 absent_section, text_section, data_section, bss_section): If
1992 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
1993 mapping to segT enum values.
1994 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1995 if these are used or defined, if BFD_ASSEMBLER.
1996 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
1997 subseg_new split into two functions.
1998 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2000 * as.h (volatile): Don't define if already defined.
2001 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2003 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2004 declare with format attribute for -Wformat checking.
2006 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2008 * app.c, config/tc-*.c: Don't include read.h, since it is already
2011 * These are based on patches from Minh Tran-le
2012 <mtranle@paris.intellicorp.com>.
2013 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2014 obj_format coffbfd and gas_target i386coff for target.
2015 (i[34]86-*-isc*): New host (uses sysv).
2016 * config/i386aix.mt: Removed (no longer used).
2017 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2019 (LDFLAGS): Added, defined as -shlib.
2020 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2021 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2022 (DOT_LABEL_PREFIX): Define.
2023 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
2024 name rather than L0\001.
2025 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2027 * symbols.c, symbols.h (local_bss_counter): Removed.
2028 * write.c (write_object_file): bss no longer uses
2029 local_bss_counter. Pass correct data and bss size to
2030 VMS_write_object_file.

2036 (size_section): Restored sanity check.
2037 (do_relocs_for): Base section address on s_paddr rather than
2038 computing it. Adjust a29k R_IHIHALF special case to account for
2039 section paddr (used to require paddr to be zero). If there are no
2040 reclos, set s_relptr to 0. Set relocation size in object_headers.
2041 (fill_section): Always set s_vaddr here, removing
2042 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2043 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2044 Set STYP_INFO for .comment.
2045 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
2046 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
2047 (crawl_symbols): Handle 8 character section name correctly. Use
2048 H_{SET,GET}_* macros.
2049 (do_linenos_for): Set lineno size in object_headers.
2050 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2051 set s_vaddr here. If string_byte_count remains 4, set it back to
2052 0, and only write strings out if there are some. Call
2053 fill_section before do_relocs_for and do_linenos_for.
2054 (obj_coff_section): Handle optional quoted second argument giving
2055 section characteristics.
2056 (obj_coff_bss): Added to handle .bss.
2057 (obj_coff_ident): Added to handle .ident (puts string in .comment

2060 (fixup_mdeps): Change to segment. Call frag_wane after
2062 (fixup_segment): Explicitly check S_IS_COMMON before making 386
2063 adjustment (already happened only for common symbols, but this is
2065 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

2077 (do_scrub_next_char): For \", return " not '.
2078 (symbol_chars): Now const.
2080 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2081 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2083 * config/obj-coff.h: Don't use #elif.
2085 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2086 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
2088 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

2113 using ZERO_BASED_SEGMENTS.
2114 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2115 never set segment address for SEG_E2 (.bss) and don't write out
2116 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2117 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2118 definitions, and don't merge tags with non-tags. Check for .bf
2119 rather than just checking whether the second character is b and
2120 the third character is f.
2121 (obj_coff_val): gcc can generate values which we don't handle
2122 correctly; discard information for now, since it only affects the
2123 debugging information.

2125 (yank_symbols): Don't merge labels.
2126 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2274 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2277 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2306 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2308 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2309 constant will not fit in an immediate field.
2310 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
2312 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

2383 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2385 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
2386 * tc-z8k.c: lots of bug fixes
2388 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2390 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2391 #elif, since it is not supported by old compilers.
2392 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2393 couple of expressions in tc-m68k.c.
2395 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2397 * read.c (cons): If NO_RELOC is defined, use it.
2399 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2401 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2403 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2404 local labels to start with a .) and set REGISTER_PREFIX to %.
2405 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2407 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2409 * messages.c: Comment changes.
2411 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)
2413 * as.h: Test if __STDC__ is defined only, don't test its value.

2418 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2421 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2423 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2424 sections starting from zero, rather than making them consecutive.
2425 This makes subsequent reloc calculations easier, esp if the object
2426 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2427 allocate lcomm in .data rather than in .bss. It seems that some
2428 tools can't cope with a non-zero sized bss before linkage.
2430 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2432 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2433 throughout. That enum no longer means what we thought it meant.

2454 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2456 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2457 .word is < -32768 or > 32767. The -J flag causes the error to be
2458 ignored. This is to catch over-sized switches generated by gcc on
2459 systems which don't support the broken .word hack.
2460 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2461 write.c (fixup_segment): check for signed .word overflow if
2462 WARN_SIGNED_OVERFLOW_WORD.

2491 From Steve Chamberlain:
2492 Makefile.in: Handle m68*-*-coff*.
2493 read.c, read.h: add mult argument to s_space
2495 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2496 Motorola and MIT syntax; gas can now assemble either type of

2540 * config/tc-m68k.c (init_table): Now const. Always include 68851
2541 data, so that "bc" is available to 68040 cache instructions.
2542 Added "tt0", "tt1", and 68ec030 variants.
2543 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2544 (enum _register): Added TT0, TT1.
2545 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2546 line number correctly in "internal error" messages. Don't print
2547 architecture-mismatch message for operand errors.

2572 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2573 has already been formatted (but may still contain %-characters).
2576 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2578 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2579 written with indirection on the last two operands, which can be
2580 either data or address registers. Added a new operand type 'r'
2581 which accepts either register type. Added '(' to notend stuff in
2582 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2928 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2929 local labels didn't work.
2930 * listing.c (list_symbol_table): don't core dump when there's no
2932 * write.c, write.h: call fix_new with the right number of args on
2934 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2937 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2939 * app.c: MRI compatibility - allow single quote to start a string.
2940 * as.c: fix typo recently introduced.
2941 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2942 * expr.c: Much rewriting, to accomodate MRI syntax for
2943 expressions. Also easier to read now.
2944 * listing.c: Put back defuns
2945 * read.c: modified to accept MRI syntax, put back listing pseudo
2946 ops so that an assembler built with NO_LISTING ignores list ops
2948 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2949 machine is a SPARC or a 29K.
2950 * config/obj-aout.c: added s_sect pseudo op
2951 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2952 fill in the timestamp.
2953 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2954 anymore, define all the relocs which the tc-<x> bit will use so we
2955 can translate from them to the coff types.
2956 * config/tc-a29k.c: reloc_type isn't ane enum any more
2957 * config/tc-m68k.c: Added NO_RELOC definition.
2959 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2961 * Makefile.in: put header files before C source for TAGS; remove
2962 references to non-existent syscalls.h.
2964 * read.c, write.c subsegs.c: back out the .bss changes.
2966 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2968 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2972 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2974 * symbols.c (local_label_name): symbols now start with ^A.
2976 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2977 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2978 generate these sections. .align: will use NOP_OPCODE or 0
2979 for padding. This is just for being nice to the
2982 * expr.c (operand): changed to generate local label "\001L0"
2983 starting with a ^A so that it is recognized as a local label.
2985 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2987 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2988 i/o opcodes - inb, inw, outb and outw. string manipulation with
2989 att syntax - scmp, slod, smov, ssca, ssto.
2991 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2992 to just after .file .
2994 In obj_crawl_symbol_chain() where it tries to put the external
2995 symbols apart, with the condition:
2996 (!S_IS_DEFINED(symbolP) &&
2997 !S_IS_DEBUG(symbolP) &&
2998 !SF_GET_STATICS(symbolP))
2999 it was moving too many symbols out. So I switch it back to the
3001 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3003 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3004 so that we don't use the F_RELFLG which make the linker complain
3005 that somebody has stripped the relocation info.
3007 Also, the AIX ld program require that the relocation table
3008 is sorted by r_vaddr like the standard ATT assembler does.
3010 [he also changed the sizeof(struct ...)'s into the coff
3011 style FOOSZ macros. I'm not sure this is right, but I can't
3012 remember why. xoxorich.]
3014 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3016 * Makefile.in, configure.in, doc: use the doc. Build it, install
3019 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3021 * read.c: white space and comments only.
3023 * configure.in: use the new atof-ns32.c for ns32k.
3025 * write.c: comment change only.
3027 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3028 aren't yet integrated.
3030 * tc-i860.[hc]: blew off the dust. Something must still be done
3031 about conflicting relocation types.
3033 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3036 * tc-i960.c, tc-sparc.c: white space and comments only.
3038 * tc-a29k.h: delete duplicate macro definition.
3040 * new file atof-ns32k.c copied from hack's last unreleased gas.
3042 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3044 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3047 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3048 ChangeLog's prior to this are sketchy at best. I have logs.
3049 They just aren't ChangeLogs.
