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

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

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

373 segment rather than sy_forward.

1512 dropping a space immediately following an identifier.
1513 * expr.c, write.c: Rewrote assert expressions to not use multiple
1514 lines; I don't think that can be done portably.
1515 * config/tc-mips.c (macro): Use $AT if target register is zero in
1516 load instruction, which it can be for a floating point load.

1590 prototypes for all static functions. Moved existing minimal
1591 debugging format support info #ifndef OBJ_ECOFF blocks.

1640 * make-gas.com: Find obstack.obj if it's not in the current
1642 * read.c (s_ignore): Don't declare is_end_of_line. It's
1643 redundant, and triggers a VMS gcc compiler bug.
1645 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1646 current segment as an argument. (Ignored in all cases but VMS.)
1647 All callers and definitions changed.

1961 logical end-of-line character, use the newline case.
1962 From Eric Youngdale:
1963 (operand): Set X_add_number field for floating-point numbers.
1964 (operand): Treat zero byte as end-of-operand.
1966 * configure.in (per-target): Look for with_bfd_assembler option.
1967 For now, only accept "no", until the merge is done.
1969 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1970 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1971 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1972 * read.c: Finish conversion to S_* macros in the VMS only
1973 parts of the program. Add "const" modifier to hex_value.
1974 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
1976 * expr.c: Add "const" modifier to hex_value.
1977 * symbols.c: Finish conversion to S_* macros in the VMS only
1978 parts of the program. Add "const" modifier to
1979 md_[long,short]_jump_size. Remove declaration of const_flag
1980 (which will be declared in obj-vms.h).
1981 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1982 Fix arguments to VMS_write_object_file.
1983 * config-gas.com: New file. Script for VMS systems to set up the
1984 configuration to build gas for VMS, and create config.status.
1985 * make-gas.com: Redone to work with new scheme.
1986 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
1988 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
1989 will swap bytes if needed on a big endian system. Use throughout
1991 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
1992 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1993 types of malformed stabs. Change parsing algorithm so that we are
1994 more certain of having all of the information that we need on hand.
1995 * obj-vms.c (final_forward_reference): New function, used to help
1996 resolve the data types of as many struct elements as possible
1997 when some part of the struct is not fully defined by the compiler.
1998 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
2000 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2001 as symbols as well in the object file. Look for external functions
2002 that start with "__vt.", and turn them into variables, since the
2003 g++ compiler is incapable of doing this.
2004 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2006 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2007 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2008 have the name of the source file yet.
2009 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2011 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2013 * read.c (s_data): Always use "data_section", since it'll map to
2014 SEG_DATA or SEG_E1 if needed.
2015 (s_lcomm): Likewise with bss_section.
2016 (s_fill): Use memset, not bzero.
2018 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2040 (big_section, reg_section, pass1_section, diff_section,
2041 absent_section, text_section, data_section, bss_section): If
2042 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2043 mapping to segT enum values.
2044 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2045 if these are used or defined, if BFD_ASSEMBLER.
2046 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2047 subseg_new split into two functions.
2048 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2050 * as.h (volatile): Don't define if already defined.
2051 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2053 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2054 declare with format attribute for -Wformat checking.
2056 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2058 * app.c, config/tc-*.c: Don't include read.h, since it is already
2061 * These are based on patches from Minh Tran-le
2062 <mtranle@paris.intellicorp.com>.
2063 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2064 obj_format coffbfd and gas_target i386coff for target.
2065 (i[34]86-*-isc*): New host (uses sysv).
2066 * config/i386aix.mt: Removed (no longer used).
2067 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2069 (LDFLAGS): Added, defined as -shlib.
2070 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2071 * config/te-sco386.h (LOCAL_LABEL): Don't define.
2072 (DOT_LABEL_PREFIX): Define.

2086 (size_section): Restored sanity check.
2087 (do_relocs_for): Base section address on s_paddr rather than
2088 computing it. Adjust a29k R_IHIHALF special case to account for
2089 section paddr (used to require paddr to be zero). If there are no
2090 reclos, set s_relptr to 0. Set relocation size in object_headers.
2091 (fill_section): Always set s_vaddr here, removing
2092 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2093 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2094 Set STYP_INFO for .comment.

2098 H_{SET,GET}_* macros.
2099 (do_linenos_for): Set lineno size in object_headers.
2100 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2101 set s_vaddr here. If string_byte_count remains 4, set it back to
2102 0, and only write strings out if there are some. Call
2103 fill_section before do_relocs_for and do_linenos_for.
2104 (obj_coff_section): Handle optional quoted second argument giving
2105 section characteristics.
2106 (obj_coff_bss): Added to handle .bss.
2107 (obj_coff_ident): Added to handle .ident (puts string in .comment

2128 (symbol_chars): Now const.
2130 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2131 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2133 * config/obj-coff.h: Don't use #elif.
2135 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2136 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2165 never set segment address for SEG_E2 (.bss) and don't write out
2166 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2167 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2168 definitions, and don't merge tags with non-tags. Check for .bf
2169 rather than just checking whether the second character is b and
2170 the third character is f.
2171 (obj_coff_val): gcc can generate values which we don't handle
2172 correctly; discard information for now, since it only affects the

2175 (yank_symbols): Don't merge labels.
2176 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2433 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2435 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
2436 * tc-z8k.c: lots of bug fixes
2438 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2440 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2441 #elif, since it is not supported by old compilers.
2442 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2443 couple of expressions in tc-m68k.c.
2445 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2447 * read.c (cons): If NO_RELOC is defined, use it.
2449 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2451 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2453 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2454 local labels to start with a .) and set REGISTER_PREFIX to %.
2455 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2457 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

2468 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2471 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2473 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2474 sections starting from zero, rather than making them consecutive.
2475 This makes subsequent reloc calculations easier, esp if the object
2476 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2477 allocate lcomm in .data rather than in .bss. It seems that some
2478 tools can't cope with a non-zero sized bss before linkage.
2480 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2482 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2483 throughout. That enum no longer means what we thought it meant.

2486 "-mno-688[58]1" options.
2488 * tc-m68k.c: Added CPU32 support.

2501 * Makefile.in (install): if $(tooldir) exists, install as in
2504 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2506 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2507 .word is < -32768 or > 32767. The -J flag causes the error to be
2508 ignored. This is to catch over-sized switches generated by gcc on
2509 systems which don't support the broken .word hack.
2510 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2511 write.c (fixup_segment): check for signed .word overflow if
2512 WARN_SIGNED_OVERFLOW_WORD.
2514 * write.c (fixup_segment): fixed missing parens in expression
2515 checking for byte or word overflow.
2517 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
2518 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
2519 WARN_SIGNED_OVERFLOW_WORD.

2529 * tc-i386.h : new coff defines
2531 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2533 * input-scrub.c (input_scrub_push): call input_file_begin, not
2535 messages.c (as_perror): print ": " between the passed in error and
2536 the strerror, like perror does.
2538 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
2540 * Makefile.in: use gas_target instead of modifying target_cpu.
2541 From Steve Chamberlain:
2542 Makefile.in: Handle m68*-*-coff*.
2543 read.c, read.h: add mult argument to s_space
2545 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2546 Motorola and MIT syntax; gas can now assemble either type of
2548 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2554 (write_object_file) call fixup_mdeps
2555 (fixup_segment) set fx_subsy to 0.
2556 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2558 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2561 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2563 * Makefile.in (LIBS): Include opcode library.

2586 little endian byte order (used to use endianness of host).
2588 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2590 * config/tc-m68k.c (init_table): Now const. Always include 68851
2591 data, so that "bc" is available to 68040 cache instructions.
2592 Added "tt0", "tt1", and 68ec030 variants.
2593 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2594 (enum _register): Added TT0, TT1.
2595 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2596 line number correctly in "internal error" messages. Don't print
2597 architecture-mismatch message for operand errors.
2599 From Colin Smith (colin@wrs.com):
2600 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
2601 than install_operand.

2622 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2623 has already been formatted (but may still contain %-characters).
2626 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2628 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2629 written with indirection on the last two operands, which can be
2630 either data or address registers. Added a new operand type 'r'
2631 which accepts either register type. Added '(' to notend stuff in
2632 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2922 * expr.c: remove limitation that local_labels_dollar or
2923 local_labels_fb must be < 10.
2925 * symbols.c: remove local_labels_dollar, replace with a function
2926 interface for a sparse array. All users adjusted.
2928 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
2930 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2932 * doc/Makefile.in: commented out line for building as-all.texinfo.
2935 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
2937 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
2939 * Makefile.in: added check target.
2941 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2943 * Makefile.in: added tooldir and program_prefix.
2945 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
2947 * write.{c,h} (fix_new): Make these declarations consistent.
2949 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
2951 * Makefile.in (strerror.o): Add rule so that broken Sun make can
2954 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
2956 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
2958 * expr.c (operand): if can't work out what sort of operand it is,
2959 then look through FLT_CHARS for a hint.
2961 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
2963 * Makefile.in, configure.in: removed traces of namesubdir,
2964 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2965 copyrights to '92, changed some from Cygnus to FSF.
2967 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
2968 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2969 copyrights to '92, changed some from Cygnus to FSF.
2971 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2973 * expr.c: If an expression is single comma, then return with
2974 SEG_ABSENT rather than an error - since the sparc front end does
2975 really strange things with things like fbge,a
2977 * as.h: include bfd.h if using many sections
2978 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2979 local labels didn't work.
2980 * listing.c (list_symbol_table): don't core dump when there's no
2982 * write.c, write.h: call fix_new with the right number of args on
2984 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2987 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2989 * app.c: MRI compatibility - allow single quote to start a string.
2990 * as.c: fix typo recently introduced.
2991 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2992 * expr.c: Much rewriting, to accomodate MRI syntax for
2993 expressions. Also easier to read now.
2994 * listing.c: Put back defuns
2995 * read.c: modified to accept MRI syntax, put back listing pseudo
2996 ops so that an assembler built with NO_LISTING ignores list ops
2998 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2999 machine is a SPARC or a 29K.
3000 * config/obj-aout.c: added s_sect pseudo op
3001 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3002 fill in the timestamp.
3003 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3004 anymore, define all the relocs which the tc-<x> bit will use so we
3005 can translate from them to the coff types.
3006 * config/tc-a29k.c: reloc_type isn't ane enum any more
3007 * config/tc-m68k.c: Added NO_RELOC definition.
3009 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3011 * Makefile.in: put header files before C source for TAGS; remove
3012 references to non-existent syscalls.h.
3014 * read.c, write.c subsegs.c: back out the .bss changes.
3016 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3018 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3022 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3024 * symbols.c (local_label_name): symbols now start with ^A.
3026 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3027 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3028 generate these sections. .align: will use NOP_OPCODE or 0
3029 for padding. This is just for being nice to the
3032 * expr.c (operand): changed to generate local label "\001L0"
3033 starting with a ^A so that it is recognized as a local label.
3035 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3037 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3038 i/o opcodes - inb, inw, outb and outw. string manipulation with
3039 att syntax - scmp, slod, smov, ssca, ssto.
3041 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3042 to just after .file .
3044 In obj_crawl_symbol_chain() where it tries to put the external
3045 symbols apart, with the condition:
3046 (!S_IS_DEFINED(symbolP) &&
3047 !S_IS_DEBUG(symbolP) &&
3048 !SF_GET_STATICS(symbolP))
3049 it was moving too many symbols out. So I switch it back to the
3051 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3053 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3054 so that we don't use the F_RELFLG which make the linker complain
3055 that somebody has stripped the relocation info.
3057 Also, the AIX ld program require that the relocation table
3058 is sorted by r_vaddr like the standard ATT assembler does.
3060 [he also changed the sizeof(struct ...)'s into the coff
3061 style FOOSZ macros. I'm not sure this is right, but I can't
3062 remember why. xoxorich.]
3064 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3066 * Makefile.in, configure.in, doc: use the doc. Build it, install
3069 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3071 * read.c: white space and comments only.
3073 * configure.in: use the new atof-ns32.c for ns32k.
3075 * write.c: comment change only.
3077 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3078 aren't yet integrated.
3080 * tc-i860.[hc]: blew off the dust. Something must still be done
3081 about conflicting relocation types.
3083 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3086 * tc-i960.c, tc-sparc.c: white space and comments only.
3088 * tc-a29k.h: delete duplicate macro definition.
3090 * new file atof-ns32k.c copied from hack's last unreleased gas.
3092 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3094 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3097 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3098 ChangeLog's prior to this are sketchy at best. I have logs.
3099 They just aren't ChangeLogs.
