950 Fri Jul 23 13:09:44 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
952 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
953 are also magic, and have special default flag settings.
954 (obj_elf_frob_symbol): Since the return value from this function
955 isn't used, don't bother calling obj_elf_write_symbol_p, since it
956 doesn't accomplish anything else.
958 * config/tc-sparc.c (md_section_align): Round up section size only
961 * symbols.c: Don't define DEBUG by default.
963 Thu Jul 22 12:09:41 1993 Ian Lance Taylor (ian@cygnus.com)

967 * expr.c (expr): Don't let absolute_section override
968 undefined_section for the return value.
970 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
971 pseudo-op with a poc_handler field of NULL, ignore it and treat it
972 as an instruction instead.
973 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
976 * config/tc-h8500.c (md_begin): Use a local variable when

988 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
989 case to set obj_format=elf. Must go before i386-*-sysv* case that
990 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
991 *-*-solaris case, and move to before *-sysv* case that wants to
992 set obj_format to coff.
993 * config/tc-i386.c (i386_operand): Change all 'exp.X_op' to

1018 * Extensive changes to permit symbols to contain any expression
1019 type and to delay the computation of the expression until the
1020 value is actually needed. This permits setting symbols to values
1021 calculated based on object code size. Expressions were changed to
1022 no longer be in a section, to stop the overloading of segment and
1023 expression type that previously occurred.
1025 * as.c (big_section, pass1_section, diff_section, absent_section):
1027 (expr_section): Added (used for dummy symbols which hold

1111 (previous_section, previous_subsection): New vars.
1112 (obj_elf_section): Save current place in case DWARF code wants us
1113 to pop back to it. Handle unquoted section name as well as quoted
1114 section name. Don't crash on invalid strings.
1115 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
1118 * config/obj-elf.h: Don't include struc-symbol.h.

1175 (macro): Call mips_emit_delays before setting mips_noreorder.
1176 Increment and decrement mips_noreorder rather than using

1203 (omagic): Removed unused variable.
1205 * Preliminary support for m88k-coff.

1224 * Removed sy_forward and replaced it with an undefined expression
1225 as the value of a symbol.

1227 sy_resolved and sy_resolving single bit fields.
1228 * symbols.c (symbol_new): Don't initialize sy_forward field.

2392 lines; I don't think that can be done portably.
2393 * config/tc-mips.c (macro): Use $AT if target register is zero in
2394 load instruction, which it can be for a floating point load.

2520 * read.c (s_ignore): Don't declare is_end_of_line. It's
2521 redundant, and triggers a VMS gcc compiler bug.
2523 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
2524 current segment as an argument. (Ignored in all cases but VMS.)
2525 All callers and definitions changed.

2857 md_[long,short]_jump_size. Remove declaration of const_flag
2858 (which will be declared in obj-vms.h).
2859 * write.c: Add "const" modifier to md_[long,short]_jump_size.
2860 Fix arguments to VMS_write_object_file.
2861 * config-gas.com: New file. Script for VMS systems to set up the
2862 configuration to build gas for VMS, and create config.status.
2863 * make-gas.com: Redone to work with new scheme.
2864 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
2866 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
2867 will swap bytes if needed on a big endian system. Use throughout
2869 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
2870 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
2871 types of malformed stabs. Change parsing algorithm so that we are
2872 more certain of having all of the information that we need on hand.
2873 * obj-vms.c (final_forward_reference): New function, used to help
2874 resolve the data types of as many struct elements as possible
2875 when some part of the struct is not fully defined by the compiler.
2876 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
2878 * obj-vms.c (VMS_write_object_file): Define all vtable psects
2879 as symbols as well in the object file. Look for external functions
2880 that start with "__vt.", and turn them into variables, since the
2881 g++ compiler is incapable of doing this.
2882 * tc-vax.c: Add '1' option for backward compatibility with older GCC
2884 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
2885 * input-scrub.c (as_where): Fix bug where as would crash if we did not
2886 have the name of the source file yet.
2887 * config/ho-vms.h: define HO_VMS, not HO_VAX.
2889 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)

2892 SEG_DATA or SEG_E1 if needed.
2893 (s_lcomm): Likewise with bss_section.
2894 (s_fill): Use memset, not bzero.
2896 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

2918 (big_section, reg_section, pass1_section, diff_section,
2919 absent_section, text_section, data_section, bss_section): If
2920 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
2921 mapping to segT enum values.
2922 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
2923 if these are used or defined, if BFD_ASSEMBLER.
2924 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
2925 subseg_new split into two functions.
2926 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
2928 * as.h (volatile): Don't define if already defined.
2929 (had_errors, had_warnings): Provide prototypes for ANSI C even if
2931 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
2932 declare with format attribute for -Wformat checking.
2934 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
2936 * app.c, config/tc-*.c: Don't include read.h, since it is already
2939 * These are based on patches from Minh Tran-le
2940 <mtranle@paris.intellicorp.com>.
2941 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
2942 obj_format coffbfd and gas_target i386coff for target.
2943 (i[34]86-*-isc*): New host (uses sysv).
2944 * config/i386aix.mt: Removed (no longer used).
2945 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
2947 (LDFLAGS): Added, defined as -shlib.
2948 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
2949 * config/te-sco386.h (LOCAL_LABEL): Don't define.

2952 name rather than L0\001.
2953 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
2955 * symbols.c, symbols.h (local_bss_counter): Removed.

2964 (size_section): Restored sanity check.
2965 (do_relocs_for): Base section address on s_paddr rather than
2966 computing it. Adjust a29k R_IHIHALF special case to account for
2967 section paddr (used to require paddr to be zero). If there are no
2968 reclos, set s_relptr to 0. Set relocation size in object_headers.
2969 (fill_section): Always set s_vaddr here, removing
2970 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2971 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2972 Set STYP_INFO for .comment.

2976 H_{SET,GET}_* macros.
2977 (do_linenos_for): Set lineno size in object_headers.
2978 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2979 set s_vaddr here. If string_byte_count remains 4, set it back to
2980 0, and only write strings out if there are some. Call
2981 fill_section before do_relocs_for and do_linenos_for.
2982 (obj_coff_section): Handle optional quoted second argument giving
2983 section characteristics.
2984 (obj_coff_bss): Added to handle .bss.
2985 (obj_coff_ident): Added to handle .ident (puts string in .comment

3005 (do_scrub_next_char): For \", return " not '.
3006 (symbol_chars): Now const.
3008 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3009 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3011 * config/obj-coff.h: Don't use #elif.
3013 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3014 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

3043 never set segment address for SEG_E2 (.bss) and don't write out
3044 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3045 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3046 definitions, and don't merge tags with non-tags. Check for .bf
3047 rather than just checking whether the second character is b and
3048 the third character is f.
3049 (obj_coff_val): gcc can generate values which we don't handle
3050 correctly; discard information for now, since it only affects the
3051 debugging information.

3053 (yank_symbols): Don't merge labels.
3054 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3331 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3332 local labels to start with a .) and set REGISTER_PREFIX to %.
3333 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

3351 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3352 sections starting from zero, rather than making them consecutive.
3353 This makes subsequent reloc calculations easier, esp if the object
3354 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3355 allocate lcomm in .data rather than in .bss. It seems that some
3356 tools can't cope with a non-zero sized bss before linkage.

3382 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3384 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3385 .word is < -32768 or > 32767. The -J flag causes the error to be
3386 ignored. This is to catch over-sized switches generated by gcc on
3387 systems which don't support the broken .word hack.
3388 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3389 write.c (fixup_segment): check for signed .word overflow if
3390 WARN_SIGNED_OVERFLOW_WORD.

3419 From Steve Chamberlain:
3420 Makefile.in: Handle m68*-*-coff*.

3434 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
3436 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3439 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3441 * Makefile.in (LIBS): Include opcode library.

3468 * config/tc-m68k.c (init_table): Now const. Always include 68851
3469 data, so that "bc" is available to 68040 cache instructions.
3470 Added "tt0", "tt1", and 68ec030 variants.
3471 (md_assemble): Complain if 68000 (only) and 68881 are specified.
3472 (enum _register): Added TT0, TT1.
3473 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
3474 line number correctly in "internal error" messages. Don't print
3475 architecture-mismatch message for operand errors.

3500 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
3501 has already been formatted (but may still contain %-characters).
3504 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
3506 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
3507 written with indirection on the last two operands, which can be
3508 either data or address registers. Added a new operand type 'r'
3509 which accepts either register type. Added '(' to notend stuff in
3510 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

3827 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
3829 * Makefile.in (strerror.o): Add rule so that broken Sun make can
3832 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
3834 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
3836 * expr.c (operand): if can't work out what sort of operand it is,
3837 then look through FLT_CHARS for a hint.
3839 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3841 * Makefile.in, configure.in: removed traces of namesubdir,
3842 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3843 copyrights to '92, changed some from Cygnus to FSF.
3845 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
3846 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3847 copyrights to '92, changed some from Cygnus to FSF.
3849 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3851 * expr.c: If an expression is single comma, then return with
3852 SEG_ABSENT rather than an error - since the sparc front end does
3853 really strange things with things like fbge,a
3855 * as.h: include bfd.h if using many sections
3856 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
3857 local labels didn't work.
3858 * listing.c (list_symbol_table): don't core dump when there's no
3860 * write.c, write.h: call fix_new with the right number of args on
3862 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
3865 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3867 * app.c: MRI compatibility - allow single quote to start a string.
3868 * as.c: fix typo recently introduced.
3869 * as.h : Don't include aout/reloc.h - it's not right for COFF!
3870 * expr.c: Much rewriting, to accomodate MRI syntax for
3871 expressions. Also easier to read now.
3872 * listing.c: Put back defuns
3873 * read.c: modified to accept MRI syntax, put back listing pseudo
3874 ops so that an assembler built with NO_LISTING ignores list ops
3876 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
3877 machine is a SPARC or a 29K.
3878 * config/obj-aout.c: added s_sect pseudo op
3879 * config/obj-coffbfd.c: lints, set the filehdr flags right and
3880 fill in the timestamp.
3881 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
3882 anymore, define all the relocs which the tc-<x> bit will use so we
3883 can translate from them to the coff types.
3884 * config/tc-a29k.c: reloc_type isn't ane enum any more
3885 * config/tc-m68k.c: Added NO_RELOC definition.
3887 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3889 * Makefile.in: put header files before C source for TAGS; remove
3890 references to non-existent syscalls.h.
3892 * read.c, write.c subsegs.c: back out the .bss changes.
3894 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
3896 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
3900 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
3902 * symbols.c (local_label_name): symbols now start with ^A.
3904 * read.c, subsegs.c, write.c obj-coff.c: added handling of
3905 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
3906 generate these sections. .align: will use NOP_OPCODE or 0
3907 for padding. This is just for being nice to the
3910 * expr.c (operand): changed to generate local label "\001L0"
3911 starting with a ^A so that it is recognized as a local label.
3913 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
3915 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
3916 i/o opcodes - inb, inw, outb and outw. string manipulation with
3917 att syntax - scmp, slod, smov, ssca, ssto.
3919 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
3920 to just after .file .
3922 In obj_crawl_symbol_chain() where it tries to put the external
3923 symbols apart, with the condition:
3924 (!S_IS_DEFINED(symbolP) &&
3925 !S_IS_DEBUG(symbolP) &&
3926 !SF_GET_STATICS(symbolP))
3927 it was moving too many symbols out. So I switch it back to the
3929 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
3931 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
3932 so that we don't use the F_RELFLG which make the linker complain
3933 that somebody has stripped the relocation info.
3935 Also, the AIX ld program require that the relocation table
3936 is sorted by r_vaddr like the standard ATT assembler does.
3938 [he also changed the sizeof(struct ...)'s into the coff
3939 style FOOSZ macros. I'm not sure this is right, but I can't
3940 remember why. xoxorich.]
3942 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
3944 * Makefile.in, configure.in, doc: use the doc. Build it, install
3947 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
3949 * read.c: white space and comments only.
3951 * configure.in: use the new atof-ns32.c for ns32k.
3953 * write.c: comment change only.
3955 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
3956 aren't yet integrated.
3958 * tc-i860.[hc]: blew off the dust. Something must still be done
3959 about conflicting relocation types.
3961 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3964 * tc-i960.c, tc-sparc.c: white space and comments only.
3966 * tc-a29k.h: delete duplicate macro definition.
3968 * new file atof-ns32k.c copied from hack's last unreleased gas.
3970 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3972 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3975 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3976 ChangeLog's prior to this are sketchy at best. I have logs.
3977 They just aren't ChangeLogs.
