3 * write.c (fix_new_exp): Handle a O_uminus expression.
5 * expr.c (expr): Don't let absolute_section override
6 undefined_section for the return value.

26 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
27 case to set obj_format=elf. Must go before i386-*-sysv* case that
28 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and

56 * Extensive changes to permit symbols to contain any expression
57 type and to delay the computation of the expression until the
58 value is actually needed. This permits setting symbols to values
59 calculated based on object code size. Expressions were changed to
60 no longer be in a section, to stop the overloading of segment and
61 expression type that previously occurred.

213 (macro): Call mips_emit_delays before setting mips_noreorder.
214 Increment and decrement mips_noreorder rather than using
215 save_reorder_condition. Don't bother to use noreorder in
216 M_L_DOB and M_L_DAB, since append_insn will not insert a NOP.

1506 prototypes for all static functions. Moved existing minimal
1507 debugging format support info #ifndef OBJ_ECOFF blocks.

1558 * read.c (s_ignore): Don't declare is_end_of_line. It's
1559 redundant, and triggers a VMS gcc compiler bug.
1561 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1562 current segment as an argument. (Ignored in all cases but VMS.)
1563 All callers and definitions changed.

1880 (operand): Treat zero byte as end-of-operand.
1882 * configure.in (per-target): Look for with_bfd_assembler option.
1883 For now, only accept "no", until the merge is done.
1885 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1886 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1887 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1888 * read.c: Finish conversion to S_* macros in the VMS only
1889 parts of the program. Add "const" modifier to hex_value.
1890 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
1892 * expr.c: Add "const" modifier to hex_value.
1893 * symbols.c: Finish conversion to S_* macros in the VMS only
1894 parts of the program. Add "const" modifier to
1895 md_[long,short]_jump_size. Remove declaration of const_flag
1896 (which will be declared in obj-vms.h).
1897 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1898 Fix arguments to VMS_write_object_file.
1899 * config-gas.com: New file. Script for VMS systems to set up the
1900 configuration to build gas for VMS, and create config.status.

1908 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1909 types of malformed stabs. Change parsing algorithm so that we are

1916 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1917 as symbols as well in the object file. Look for external functions

1956 (big_section, reg_section, pass1_section, diff_section,
1957 absent_section, text_section, data_section, bss_section): If
1958 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
1959 mapping to segT enum values.

1961 if these are used or defined, if BFD_ASSEMBLER.
1962 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

1966 * as.h (volatile): Don't define if already defined.
1967 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1969 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1970 declare with format attribute for -Wformat checking.
1972 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
1974 * app.c, config/tc-*.c: Don't include read.h, since it is already
1977 * These are based on patches from Minh Tran-le
1978 <mtranle@paris.intellicorp.com>.
1979 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1980 obj_format coffbfd and gas_target i386coff for target.
1981 (i[34]86-*-isc*): New host (uses sysv).
1982 * config/i386aix.mt: Removed (no longer used).
1983 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
1985 (LDFLAGS): Added, defined as -shlib.
1986 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1987 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1988 (DOT_LABEL_PREFIX): Define.
1989 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1990 name rather than L0\001.
1991 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
1993 * symbols.c, symbols.h (local_bss_counter): Removed.
1994 * write.c (write_object_file): bss no longer uses
1995 local_bss_counter. Pass correct data and bss size to
1996 VMS_write_object_file.

2002 (size_section): Restored sanity check.
2003 (do_relocs_for): Base section address on s_paddr rather than
2004 computing it. Adjust a29k R_IHIHALF special case to account for
2005 section paddr (used to require paddr to be zero). If there are no
2006 reclos, set s_relptr to 0. Set relocation size in object_headers.
2007 (fill_section): Always set s_vaddr here, removing
2008 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
2009 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
2010 Set STYP_INFO for .comment.

2015 (do_linenos_for): Set lineno size in object_headers.
2016 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
2017 set s_vaddr here. If string_byte_count remains 4, set it back to
2018 0, and only write strings out if there are some. Call
2019 fill_section before do_relocs_for and do_linenos_for.
2020 (obj_coff_section): Handle optional quoted second argument giving
2021 section characteristics.
2022 (obj_coff_bss): Added to handle .bss.
2023 (obj_coff_ident): Added to handle .ident (puts string in .comment
2025 (obj_coff_lcomm): Put common symbols in .bss, not .data.
2026 (fixup_mdeps): Change to segment. Call frag_wane after

2043 (do_scrub_next_char): For \", return " not '.
2044 (symbol_chars): Now const.
2046 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2047 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2049 * config/obj-coff.h: Don't use #elif.
2051 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2052 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2079 using ZERO_BASED_SEGMENTS.
2080 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
2081 never set segment address for SEG_E2 (.bss) and don't write out
2082 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2083 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2084 definitions, and don't merge tags with non-tags. Check for .bf
2085 rather than just checking whether the second character is b and
2086 the third character is f.
2087 (obj_coff_val): gcc can generate values which we don't handle
2088 correctly; discard information for now, since it only affects the
2089 debugging information.

2091 (yank_symbols): Don't merge labels.
2092 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2237 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
2238 could be doing emulation.
2240 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2243 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2272 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
2274 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2275 constant will not fit in an immediate field.
2276 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2311 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2313 * Support for i386-sysv.
2314 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

2338 * tc-m68k.c (get_num): make it work for all segments, not just the
2341 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
2343 * configure.in: recognize i386-*-bsd emulation.

2352 * tc-z8k.c: lots of bug fixes
2354 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2356 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2357 #elif, since it is not supported by old compilers.
2358 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2359 couple of expressions in tc-m68k.c.
2361 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2363 * read.c (cons): If NO_RELOC is defined, use it.
2365 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2367 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2369 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2370 local labels to start with a .) and set REGISTER_PREFIX to %.
2371 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2373 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
2375 * messages.c: Comment changes.
2377 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

2384 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2387 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2389 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2390 sections starting from zero, rather than making them consecutive.
2391 This makes subsequent reloc calculations easier, esp if the object
2392 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2393 allocate lcomm in .data rather than in .bss. It seems that some
2394 tools can't cope with a non-zero sized bss before linkage.
2396 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2398 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2399 throughout. That enum no longer means what we thought it meant.
2401 * tc-m68k.c (md_assemble, md_parse_option): Handle new
2402 "-mno-688[58]1" options.
2404 * tc-m68k.c: Added CPU32 support.

2412 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
2413 Change LIBDEPS dependence to LIBS.
2415 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
2417 * Makefile.in (install): if $(tooldir) exists, install as in
2420 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2422 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2423 .word is < -32768 or > 32767. The -J flag causes the error to be
2424 ignored. This is to catch over-sized switches generated by gcc on
2425 systems which don't support the broken .word hack.
2426 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2427 write.c (fixup_segment): check for signed .word overflow if
2428 WARN_SIGNED_OVERFLOW_WORD.
2430 * write.c (fixup_segment): fixed missing parens in expression
2431 checking for byte or word overflow.

2915 machine is a SPARC or a 29K.
2916 * config/obj-aout.c: added s_sect pseudo op
2917 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2918 fill in the timestamp.

2930 * read.c, write.c subsegs.c: back out the .bss changes.
2932 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2934 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

2940 * symbols.c (local_label_name): symbols now start with ^A.
2942 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2943 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2944 generate these sections. .align: will use NOP_OPCODE or 0
2945 for padding. This is just for being nice to the
2948 * expr.c (operand): changed to generate local label "\001L0"
2949 starting with a ^A so that it is recognized as a local label.
2951 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2953 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2954 i/o opcodes - inb, inw, outb and outw. string manipulation with
2955 att syntax - scmp, slod, smov, ssca, ssto.
2957 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2958 to just after .file .
2960 In obj_crawl_symbol_chain() where it tries to put the external
2961 symbols apart, with the condition:
2962 (!S_IS_DEFINED(symbolP) &&
2963 !S_IS_DEBUG(symbolP) &&
2964 !SF_GET_STATICS(symbolP))
2965 it was moving too many symbols out. So I switch it back to the
2967 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2969 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2970 so that we don't use the F_RELFLG which make the linker complain
2971 that somebody has stripped the relocation info.
2973 Also, the AIX ld program require that the relocation table
2974 is sorted by r_vaddr like the standard ATT assembler does.
2976 [he also changed the sizeof(struct ...)'s into the coff
2977 style FOOSZ macros. I'm not sure this is right, but I can't
2978 remember why. xoxorich.]

2982 * Makefile.in, configure.in, doc: use the doc. Build it, install
2985 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2987 * read.c: white space and comments only.
2989 * configure.in: use the new atof-ns32.c for ns32k.
2991 * write.c: comment change only.
2993 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2994 aren't yet integrated.
2996 * tc-i860.[hc]: blew off the dust. Something must still be done
2997 about conflicting relocation types.
2999 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
3002 * tc-i960.c, tc-sparc.c: white space and comments only.
3004 * tc-a29k.h: delete duplicate macro definition.
3006 * new file atof-ns32k.c copied from hack's last unreleased gas.
3008 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
3010 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
3013 * nearly everything. flush ChangeLog, package as gas-1.92.1.
3014 ChangeLog's prior to this are sketchy at best. I have logs.
3015 They just aren't ChangeLogs.
