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

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

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

367 segment rather than sy_forward.

1506 dropping a space immediately following an identifier.
1507 * expr.c, write.c: Rewrote assert expressions to not use multiple
1508 lines; I don't think that can be done portably.
1509 * config/tc-mips.c (macro): Use $AT if target register is zero in
1510 load instruction, which it can be for a floating point load.

1584 prototypes for all static functions. Moved existing minimal
1585 debugging format support info #ifndef OBJ_ECOFF blocks.

1634 * make-gas.com: Find obstack.obj if it's not in the current
1636 * read.c (s_ignore): Don't declare is_end_of_line. It's
1637 redundant, and triggers a VMS gcc compiler bug.
1639 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1640 current segment as an argument. (Ignored in all cases but VMS.)
1641 All callers and definitions changed.

1960 * configure.in (per-target): Look for with_bfd_assembler option.
1961 For now, only accept "no", until the merge is done.
1963 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1964 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1965 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1966 * read.c: Finish conversion to S_* macros in the VMS only
1967 parts of the program. Add "const" modifier to hex_value.
1968 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
1970 * expr.c: Add "const" modifier to hex_value.
1971 * symbols.c: Finish conversion to S_* macros in the VMS only
1972 parts of the program. Add "const" modifier to
1973 md_[long,short]_jump_size. Remove declaration of const_flag
1974 (which will be declared in obj-vms.h).
1975 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1976 Fix arguments to VMS_write_object_file.
1977 * config-gas.com: New file. Script for VMS systems to set up the
1978 configuration to build gas for VMS, and create config.status.
1979 * make-gas.com: Redone to work with new scheme.
1980 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
1982 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
1983 will swap bytes if needed on a big endian system. Use throughout
1985 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
1986 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1987 types of malformed stabs. Change parsing algorithm so that we are
1988 more certain of having all of the information that we need on hand.
1989 * obj-vms.c (final_forward_reference): New function, used to help
1990 resolve the data types of as many struct elements as possible
1991 when some part of the struct is not fully defined by the compiler.
1992 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
1994 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1995 as symbols as well in the object file. Look for external functions
1996 that start with "__vt.", and turn them into variables, since the
1997 g++ compiler is incapable of doing this.
1998 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2000 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2001 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2002 have the name of the source file yet.
2003 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2005 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
2007 * read.c (s_data): Always use "data_section", since it'll map to
2008 SEG_DATA or SEG_E1 if needed.
2009 (s_lcomm): Likewise with bss_section.
2010 (s_fill): Use memset, not bzero.
2012 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2037 mapping to segT enum values.
2038 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2039 if these are used or defined, if BFD_ASSEMBLER.
2040 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2041 subseg_new split into two functions.
2042 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2044 * as.h (volatile): Don't define if already defined.
2045 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2047 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2048 declare with format attribute for -Wformat checking.
2050 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2052 * app.c, config/tc-*.c: Don't include read.h, since it is already
2055 * These are based on patches from Minh Tran-le
2056 <mtranle@paris.intellicorp.com>.
2057 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2058 obj_format coffbfd and gas_target i386coff for target.
2059 (i[34]86-*-isc*): New host (uses sysv).
2060 * config/i386aix.mt: Removed (no longer used).
2061 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2063 (LDFLAGS): Added, defined as -shlib.
2064 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2065 * config/te-sco386.h (LOCAL_LABEL): Don't define.

2080 (size_section): Restored sanity check.
2081 (do_relocs_for): Base section address on s_paddr rather than
2082 computing it. Adjust a29k R_IHIHALF special case to account for
2083 section paddr (used to require paddr to be zero). If there are no
2084 reclos, set s_relptr to 0. Set relocation size in object_headers.
2085 (fill_section): Always set s_vaddr here, removing
2086 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2087 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2088 Set STYP_INFO for .comment.

2093 (do_linenos_for): Set lineno size in object_headers.
2094 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2095 set s_vaddr here. If string_byte_count remains 4, set it back to
2096 0, and only write strings out if there are some. Call
2097 fill_section before do_relocs_for and do_linenos_for.
2098 (obj_coff_section): Handle optional quoted second argument giving
2099 section characteristics.
2100 (obj_coff_bss): Added to handle .bss.
2101 (obj_coff_ident): Added to handle .ident (puts string in .comment

2122 (symbol_chars): Now const.
2124 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2125 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2127 * config/obj-coff.h: Don't use #elif.
2129 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2130 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2159 never set segment address for SEG_E2 (.bss) and don't write out
2160 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2161 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2162 definitions, and don't merge tags with non-tags. Check for .bf
2163 rather than just checking whether the second character is b and
2164 the third character is f.
2165 (obj_coff_val): gcc can generate values which we don't handle
2166 correctly; discard information for now, since it only affects the

2169 (yank_symbols): Don't merge labels.
2170 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2432 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2434 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2435 #elif, since it is not supported by old compilers.
2436 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2437 couple of expressions in tc-m68k.c.
2439 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2441 * read.c (cons): If NO_RELOC is defined, use it.
2443 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2445 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2447 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2448 local labels to start with a .) and set REGISTER_PREFIX to %.
2449 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2451 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

2462 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2465 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2467 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2468 sections starting from zero, rather than making them consecutive.
2469 This makes subsequent reloc calculations easier, esp if the object
2470 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2471 allocate lcomm in .data rather than in .bss. It seems that some
2472 tools can't cope with a non-zero sized bss before linkage.
2474 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2476 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2477 throughout. That enum no longer means what we thought it meant.

2480 "-mno-688[58]1" options.
2482 * tc-m68k.c: Added CPU32 support.

2495 * Makefile.in (install): if $(tooldir) exists, install as in
2498 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2500 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2501 .word is < -32768 or > 32767. The -J flag causes the error to be
2502 ignored. This is to catch over-sized switches generated by gcc on
2503 systems which don't support the broken .word hack.
2504 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2505 write.c (fixup_segment): check for signed .word overflow if
2506 WARN_SIGNED_OVERFLOW_WORD.
2508 * write.c (fixup_segment): fixed missing parens in expression
2509 checking for byte or word overflow.
2511 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

2525 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2527 * input-scrub.c (input_scrub_push): call input_file_begin, not
2529 messages.c (as_perror): print ": " between the passed in error and
2530 the strerror, like perror does.
2532 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

2535 From Steve Chamberlain:
2536 Makefile.in: Handle m68*-*-coff*.
2537 read.c, read.h: add mult argument to s_space
2539 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2540 Motorola and MIT syntax; gas can now assemble either type of
2542 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2548 (write_object_file) call fixup_mdeps
2549 (fixup_segment) set fx_subsy to 0.
2550 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2552 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2555 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2557 * Makefile.in (LIBS): Include opcode library.

2582 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2584 * config/tc-m68k.c (init_table): Now const. Always include 68851
2585 data, so that "bc" is available to 68040 cache instructions.
2586 Added "tt0", "tt1", and 68ec030 variants.
2587 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2588 (enum _register): Added TT0, TT1.
2589 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2590 line number correctly in "internal error" messages. Don't print
2591 architecture-mismatch message for operand errors.
2593 From Colin Smith (colin@wrs.com):
2594 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
2595 than install_operand.

2616 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2617 has already been formatted (but may still contain %-characters).
2620 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2622 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2623 written with indirection on the last two operands, which can be
2624 either data or address registers. Added a new operand type 'r'
2625 which accepts either register type. Added '(' to notend stuff in
2626 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2924 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2926 * doc/Makefile.in: commented out line for building as-all.texinfo.
2929 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
2931 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
2933 * Makefile.in: added check target.
2935 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2937 * Makefile.in: added tooldir and program_prefix.
2939 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
2941 * write.{c,h} (fix_new): Make these declarations consistent.
2943 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
2945 * Makefile.in (strerror.o): Add rule so that broken Sun make can
2948 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
2950 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
2952 * expr.c (operand): if can't work out what sort of operand it is,
2953 then look through FLT_CHARS for a hint.
2955 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
2957 * Makefile.in, configure.in: removed traces of namesubdir,
2958 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2959 copyrights to '92, changed some from Cygnus to FSF.
2961 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
2962 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2963 copyrights to '92, changed some from Cygnus to FSF.
2965 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2967 * expr.c: If an expression is single comma, then return with
2968 SEG_ABSENT rather than an error - since the sparc front end does
2969 really strange things with things like fbge,a
2971 * as.h: include bfd.h if using many sections
2972 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2973 local labels didn't work.
2974 * listing.c (list_symbol_table): don't core dump when there's no
2976 * write.c, write.h: call fix_new with the right number of args on
2978 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2981 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2983 * app.c: MRI compatibility - allow single quote to start a string.
2984 * as.c: fix typo recently introduced.
2985 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2986 * expr.c: Much rewriting, to accomodate MRI syntax for
2987 expressions. Also easier to read now.
2988 * listing.c: Put back defuns
2989 * read.c: modified to accept MRI syntax, put back listing pseudo
2990 ops so that an assembler built with NO_LISTING ignores list ops
2992 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2993 machine is a SPARC or a 29K.
2994 * config/obj-aout.c: added s_sect pseudo op
2995 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2996 fill in the timestamp.
2997 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2998 anymore, define all the relocs which the tc-<x> bit will use so we
2999 can translate from them to the coff types.
3000 * config/tc-a29k.c: reloc_type isn't ane enum any more
3001 * config/tc-m68k.c: Added NO_RELOC definition.
3003 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3005 * Makefile.in: put header files before C source for TAGS; remove
3006 references to non-existent syscalls.h.
3008 * read.c, write.c subsegs.c: back out the .bss changes.
3010 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3012 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3016 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3018 * symbols.c (local_label_name): symbols now start with ^A.
3020 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3021 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3022 generate these sections. .align: will use NOP_OPCODE or 0
3023 for padding. This is just for being nice to the
3026 * expr.c (operand): changed to generate local label "\001L0"
3027 starting with a ^A so that it is recognized as a local label.
3029 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3031 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3032 i/o opcodes - inb, inw, outb and outw. string manipulation with
3033 att syntax - scmp, slod, smov, ssca, ssto.
3035 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3036 to just after .file .
3038 In obj_crawl_symbol_chain() where it tries to put the external
3039 symbols apart, with the condition:
3040 (!S_IS_DEFINED(symbolP) &&
3041 !S_IS_DEBUG(symbolP) &&
3042 !SF_GET_STATICS(symbolP))
3043 it was moving too many symbols out. So I switch it back to the
3045 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3047 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3048 so that we don't use the F_RELFLG which make the linker complain
3049 that somebody has stripped the relocation info.
3051 Also, the AIX ld program require that the relocation table
3052 is sorted by r_vaddr like the standard ATT assembler does.
3054 [he also changed the sizeof(struct ...)'s into the coff
3055 style FOOSZ macros. I'm not sure this is right, but I can't
3056 remember why. xoxorich.]
3058 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3060 * Makefile.in, configure.in, doc: use the doc. Build it, install
3063 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3065 * read.c: white space and comments only.
3067 * configure.in: use the new atof-ns32.c for ns32k.
3069 * write.c: comment change only.
3071 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3072 aren't yet integrated.
3074 * tc-i860.[hc]: blew off the dust. Something must still be done
3075 about conflicting relocation types.
3077 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3080 * tc-i960.c, tc-sparc.c: white space and comments only.
3082 * tc-a29k.h: delete duplicate macro definition.
3084 * new file atof-ns32k.c copied from hack's last unreleased gas.
3086 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3088 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3091 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3092 ChangeLog's prior to this are sketchy at best. I have logs.
3093 They just aren't ChangeLogs.
