3 * Extensive changes to permit symbols to contain any expression
4 type and to delay the computation of the expression until the
5 value is actually needed. This permits setting symbols to values
6 calculated based on object code size. Expressions were changed to
7 no longer be in a section, to stop the overloading of segment and
8 expression type that previously occurred.

1330 avoid some redefinition complaints on some systems.

1378 * config/tc-mips.c (macro): Use $AT if target register is zero in
1379 load instruction, which it can be for a floating point load.

1503 * make-gas.com: Find obstack.obj if it's not in the current
1505 * read.c (s_ignore): Don't declare is_end_of_line. It's
1506 redundant, and triggers a VMS gcc compiler bug.
1508 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1509 current segment as an argument. (Ignored in all cases but VMS.)

1830 For now, only accept "no", until the merge is done.
1832 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1833 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

1839 * expr.c: Add "const" modifier to hex_value.
1840 * symbols.c: Finish conversion to S_* macros in the VMS only

1842 md_[long,short]_jump_size. Remove declaration of const_flag
1843 (which will be declared in obj-vms.h).
1844 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1845 Fix arguments to VMS_write_object_file.
1846 * config-gas.com: New file. Script for VMS systems to set up the

1906 mapping to segT enum values.
1907 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1908 if these are used or defined, if BFD_ASSEMBLER.
1909 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
1910 subseg_new split into two functions.
1911 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
1913 * as.h (volatile): Don't define if already defined.

1949 (size_section): Restored sanity check.
1950 (do_relocs_for): Base section address on s_paddr rather than
1951 computing it. Adjust a29k R_IHIHALF special case to account for
1952 section paddr (used to require paddr to be zero). If there are no
1953 reclos, set s_relptr to 0. Set relocation size in object_headers.
1954 (fill_section): Always set s_vaddr here, removing
1955 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
1956 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
1957 Set STYP_INFO for .comment.
1958 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
1959 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

1962 (do_linenos_for): Set lineno size in object_headers.
1963 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
1964 set s_vaddr here. If string_byte_count remains 4, set it back to
1965 0, and only write strings out if there are some. Call
1966 fill_section before do_relocs_for and do_linenos_for.
1967 (obj_coff_section): Handle optional quoted second argument giving
1968 section characteristics.
1969 (obj_coff_bss): Added to handle .bss.
1970 (obj_coff_ident): Added to handle .ident (puts string in .comment
1972 (obj_coff_lcomm): Put common symbols in .bss, not .data.
1973 (fixup_mdeps): Change to segment. Call frag_wane after
1975 (fixup_segment): Explicitly check S_IS_COMMON before making 386
1976 adjustment (already happened only for common symbols, but this is

1991 (symbol_chars): Now const.
1993 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
1994 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
1996 * config/obj-coff.h: Don't use #elif.
1998 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
1999 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2028 never set segment address for SEG_E2 (.bss) and don't write out
2029 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2030 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2031 definitions, and don't merge tags with non-tags. Check for .bf
2032 rather than just checking whether the second character is b and
2033 the third character is f.
2034 (obj_coff_val): gcc can generate values which we don't handle
2035 correctly; discard information for now, since it only affects the
2036 debugging information.

2038 (yank_symbols): Don't merge labels.
2039 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2185 could be doing emulation.
2187 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2190 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2221 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2222 constant will not fit in an immediate field.
2223 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2299 * tc-z8k.c: lots of bug fixes
2301 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2303 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2304 #elif, since it is not supported by old compilers.
2305 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2306 couple of expressions in tc-m68k.c.
2308 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

2316 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2317 local labels to start with a .) and set REGISTER_PREFIX to %.
2318 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2320 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

2334 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2336 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2337 sections starting from zero, rather than making them consecutive.
2338 This makes subsequent reloc calculations easier, esp if the object
2339 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2340 allocate lcomm in .data rather than in .bss. It seems that some
2341 tools can't cope with a non-zero sized bss before linkage.
2343 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2345 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2346 throughout. That enum no longer means what we thought it meant.

2349 "-mno-688[58]1" options.
2351 * tc-m68k.c: Added CPU32 support.

2364 * Makefile.in (install): if $(tooldir) exists, install as in
2367 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2369 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2370 .word is < -32768 or > 32767. The -J flag causes the error to be
2371 ignored. This is to catch over-sized switches generated by gcc on
2372 systems which don't support the broken .word hack.
2373 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2374 write.c (fixup_segment): check for signed .word overflow if
2375 WARN_SIGNED_OVERFLOW_WORD.
2377 * write.c (fixup_segment): fixed missing parens in expression
2378 checking for byte or word overflow.

2392 * tc-i386.h : new coff defines
2394 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2396 * input-scrub.c (input_scrub_push): call input_file_begin, not
2398 messages.c (as_perror): print ": " between the passed in error and
2399 the strerror, like perror does.
2401 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
2403 * Makefile.in: use gas_target instead of modifying target_cpu.
2404 From Steve Chamberlain:
2405 Makefile.in: Handle m68*-*-coff*.
2406 read.c, read.h: add mult argument to s_space
2408 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2409 Motorola and MIT syntax; gas can now assemble either type of
2411 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2413 m68kcoff.mt: for m68k COFF.
2414 obj-coffbfd.c: (fixup_mdeps) added
2415 (size_section) removed bad sanity check
2416 (fill_section) added rs_machine_dependent case
2417 (write_object_file) call fixup_mdeps
2418 (fixup_segment) set fx_subsy to 0.
2419 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2421 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2424 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2426 * Makefile.in (LIBS): Include opcode library.
2428 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
2430 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
2431 including zero are accepted, pass +0.0.

2453 * config/tc-m68k.c (init_table): Now const. Always include 68851
2454 data, so that "bc" is available to 68040 cache instructions.
2455 Added "tt0", "tt1", and 68ec030 variants.
2456 (md_assemble): Complain if 68000 (only) and 68881 are specified.

2489 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2491 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2492 written with indirection on the last two operands, which can be
2493 either data or address registers. Added a new operand type 'r'
2494 which accepts either register type. Added '(' to notend stuff in
2495 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2607 characteristics have been), default to 68020. Don't need extra
2608 quotes around error string.

2744 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
2746 * Makefile.in (install): Install into $(tooldir)/bin, since that's
2747 where gcc looks for it.

2826 * Makefile.in, configure.in: removed traces of namesubdir,

2830 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
2831 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2832 copyrights to '92, changed some from Cygnus to FSF.
2834 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2836 * expr.c: If an expression is single comma, then return with
2837 SEG_ABSENT rather than an error - since the sparc front end does
2838 really strange things with things like fbge,a
2840 * as.h: include bfd.h if using many sections
2841 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2842 local labels didn't work.
2843 * listing.c (list_symbol_table): don't core dump when there's no
2845 * write.c, write.h: call fix_new with the right number of args on
2847 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2850 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2852 * app.c: MRI compatibility - allow single quote to start a string.
2853 * as.c: fix typo recently introduced.
2854 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2855 * expr.c: Much rewriting, to accomodate MRI syntax for
2856 expressions. Also easier to read now.
2857 * listing.c: Put back defuns
2858 * read.c: modified to accept MRI syntax, put back listing pseudo
2859 ops so that an assembler built with NO_LISTING ignores list ops
2861 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2862 machine is a SPARC or a 29K.
2863 * config/obj-aout.c: added s_sect pseudo op
2864 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2865 fill in the timestamp.
2866 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2867 anymore, define all the relocs which the tc-<x> bit will use so we
2868 can translate from them to the coff types.
2869 * config/tc-a29k.c: reloc_type isn't ane enum any more
2870 * config/tc-m68k.c: Added NO_RELOC definition.
2872 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2874 * Makefile.in: put header files before C source for TAGS; remove
2875 references to non-existent syscalls.h.
2877 * read.c, write.c subsegs.c: back out the .bss changes.
2879 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2881 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2885 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2887 * symbols.c (local_label_name): symbols now start with ^A.
2889 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2890 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2891 generate these sections. .align: will use NOP_OPCODE or 0
2892 for padding. This is just for being nice to the
2895 * expr.c (operand): changed to generate local label "\001L0"
2896 starting with a ^A so that it is recognized as a local label.
2898 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2900 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2901 i/o opcodes - inb, inw, outb and outw. string manipulation with
2902 att syntax - scmp, slod, smov, ssca, ssto.
2904 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2905 to just after .file .
2907 In obj_crawl_symbol_chain() where it tries to put the external
2908 symbols apart, with the condition:
2909 (!S_IS_DEFINED(symbolP) &&
2910 !S_IS_DEBUG(symbolP) &&
2911 !SF_GET_STATICS(symbolP))
2912 it was moving too many symbols out. So I switch it back to the
2914 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2916 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2917 so that we don't use the F_RELFLG which make the linker complain
2918 that somebody has stripped the relocation info.
2920 Also, the AIX ld program require that the relocation table
2921 is sorted by r_vaddr like the standard ATT assembler does.
2923 [he also changed the sizeof(struct ...)'s into the coff
2924 style FOOSZ macros. I'm not sure this is right, but I can't
2925 remember why. xoxorich.]
2927 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
2929 * Makefile.in, configure.in, doc: use the doc. Build it, install
2932 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)

2949 * tc-i960.c, tc-sparc.c: white space and comments only.

2957 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
