1194 * config/tc-mips.c (append_insn): Permit branches to be switched
1195 with the preceding instruction even if .set nobopt has been seen.
1196 .set nobopt actually controls whether to bring up an instruction

1338 which has been fixed, and in the case of elf_tc_make_sections is
1339 redundant with elf_tc_final_processing.

1454 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1455 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1456 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with

1472 (macro): Handle EMBEDDED_PIC in all PIC cases.
1473 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1474 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1475 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1476 works). Do not permit -G with SVR4_PIC.
1477 (s_abicalls): Warn if -G was used, and force -G 0.
1478 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1479 anything but a.out, not just for ELF. For ECOFF, don't generate a

1484 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1486 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1487 parameters to avoid losing when compiling with HP CC.
1488 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1490 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1492 * Makefile.in (config-stamp): If `defs' is defined, emit a
1493 preprocessor directive to create a macro named by this value into
1494 config.new; don't explicitly go for BFD_ASSEMBLER.
1495 * configure.in: Define `defs', not `BFDDEF'. Set it to
1496 MANY_SEGMENTS for any obj-coffbfd target.
1497 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1498 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1500 (LOCAL_LOADLIBES): Deleted.
1501 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1502 * config/m88kcoff.mt (TDEFINES): Ditto.

1528 bfd_set_symtab is called.
1529 (dump_section_relocs): Note whether a symbol is a section symbol
1531 (adjust_reloc_syms): For now, always supply an absolute symbol for
1532 fixups without symbols but not yet `done'. Use section_symbol to
1533 get the symbol, instead of going directly for abs_symbol.
1534 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1535 reloc is not a section symbol and is not in the symbol table.
1536 (set_symtab): New function, broken out from write_object_file.
1537 Counts symbol table instead of relying on an earlier count.
1538 (write_object_file): Call set_symtab, but do it after potentially
1539 invoking the *_frob_file macros. Don't bother counting symbols.
1540 Call symbol_remove, instead of expanding it in place. Moved the
1541 conditionalized `object_file_size' declaration down to
1542 conditionalized block where it's used. When using the absolute
1543 symbol for a fixup without a symbol, set sy_used_in_reloc.
1544 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1545 the correct symbol for the absolute section.
1547 * subsegs.c (section_symbol): Use symbol_new instead of
1548 symbol_make, since we may want it to go into the symbol table.
1549 Make the new symbol have internal linkage. If
1550 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1551 symbol with the newly created GAS symbol.
1552 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
1553 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

1560 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
1561 (sparc_ip, label "immediate"): Reject constants for pcrel
1562 instructions only if the relocation type indicates a "call"
1563 instruction and the offset is within range of a "jmpl %g0". If
1564 it's not in range, use the absolute section symbol plus an offset.
1565 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
1567 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
1569 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
1572 * configure.in: Eliminated all targets using obj-coff but not
1573 defining BFD_ASSEMBLER; I think all such targets that are
1574 supported will be matched by real CPU-OS combinations earlier in
1576 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
1577 some comments about the dpx2 configuration, but left it disabled,
1578 since it couldn't be reached before.
1579 (target a29k-amd-ebmonold): Deleted.

1589 the 'j' operand if there are no further alternatives for this
1592 * config/obj-coffbfd.c (adjust_stab_section): Initialize
1593 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
1594 is not SEG_UNKNOWN rather than checking whether it is >= 0.
1596 * config/tc-mips.c (mips_align): Take new argument, label, and use
1597 it instead of global insn_label.
1598 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
1599 call to mips_emit_delay and pass it to mips_align.
1601 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1603 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
1605 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
1606 argument to a .callinfo directive. Don't loop forever on errors.

1614 S_IS_EXTERNAL when deciding whether to discard a symbol.
1616 * config-gas.com: Scan Makefile.in, not version.c, for current
1617 version number. Delete all versions of temp files when finished
1618 with them. Create config.h.

1621 values to reduce number of lookups with S_GET_VALUE. Skip debug
1622 symbols to avoid "a really nasty bug". (From Holger Teutsch,
1623 holger@botbso.rhein-main.de.)
1624 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
1625 field. (Also from Holger Teutsch.) Watch for a would-be register
1626 mask that spans frags.
1628 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
1629 this_base, not line_base. (Patch from Andreas Arens,

1633 look local if they're exported or undefined. Used to be done for
1636 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

1640 (lex_type): Use it for `%'.
1642 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

3770 in favor of more specific names. (E.g., when we get Alpha
3771 support, we'll still only support VMS for Vax.)
3773 * config/tc-sparc.h (md_end): New macro.
3774 * config/tc-sparc.c (md_end): Function deleted.
3775 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd
3776 version compiling. All sparc targets will use bfd now.

3779 Changes from Jeff Law and Peter Hoogenboom:
3781 * read.c (next_char_of_string): Limit octal character constants to
3784 * config/tc-hppa.h: Major cleanup. Use GNU-style comments. Warn
3785 against placing additional object-file dependent code here. Warn
3786 against contaminating all of GAS with the internals of tc-hppa.c
3787 through inclusion of tc-hppa.h. Delete all forward declarations
3788 for functions only used within tc-hppa.c, likewise for structures,
3789 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
3790 conditional code in a few small places.
3792 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
3793 structures, global variables, forward declarations together.
3794 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
3795 conditional code -- try to group conditional code together
3796 into a few places. Make all functions and variables which
3797 are only used within tc-hppa.c static. PARAMize all functions.
3798 Add comments to functions. Delete unused functions, variables,
3799 #defines, etc. Delete unused members within structures. Delete
3800 ldil;ble hacks -- it is believed they were installed to work
3801 around old gas bugs. Avoid using mixed case for local
3802 functions, variables, and structures. Fix formatting problems
3803 not found by GNU-indent. Add FIXME notices for things which
3804 should be worked on the near future. Delete lots of old
3805 useless (1.36 PA-SOM) code.
3807 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
3808 field of the fixS structure. Needed to build unwind
3809 descriptors correctly.

3817 which do not involve function symbols.
3819 * config/tc-hppa.h: Reindent with GNU-indent. Delete references

3825 of elf32_symbol_type.
3826 (pa_export_args): Likewise.
3827 (elf_hppa_final_processing): Likewise.
3828 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

3833 * config/tc-hppa.c: (md_section_align): Align all sections to
3834 a multiple of the section alignment rather than always a
3837 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
3838 bits are zero (eg they specify no relocations), then do not even
3839 bother adding their entries to thesymextn section.

3884 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
3886 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
3887 ELF, since the ELF object format does not have these type of
3888 relocations. Change the abort into as as_bad and return
3889 BFD_RELOC_NONE to silence compiler warnings.
3890 (md_assemble): Keep track of the instruction size. Allow white

6276 a29k .bss section; the mondfe program doesn't like it.

6291 (srcdir): Delete second, bogus definition.
6292 (as.info): Look for as-*.texinfo in current directory rather than

6297 source directory, if that's not the current directory.
6299 * configure.in (per-host): Accept MIPS host with BSD version
6301 (per-target): Classify i486 as i386. Use generic cpu_type instead

6320 * config/obj-coffbfd.c (do_relocs_for): Don't allocate storage or
6321 process relocs if there aren't any relocs to process. Avoids
6322 malloc/free bug on SCO too.

6325 avoid some redefinition complaints on some systems.
6326 (const, volatile): Don't need these conditionally defined if we
6327 use CONST and VOLATILE from ansidecl.h.
6328 (seg_name): Use CONST, not const.
6330 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
6332 * config/tc-mips.c: Reindented to GNU standards.
6334 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
6336 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
6337 (fixup_segment): Add a29k special case; the linker is not prepared
6338 to see a segment offset here.
6340 * app.c (do_scrub_next_char): Added new state, 10, modifying state
6341 9 to only keep a space in between identifier characters.
6343 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6345 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6346 srcdir, might be in objdir.
6348 * doc/Makefile.in: dvi depends on as.dvi

6366 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
6367 bignums, but don't emit error message.
6369 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
6371 * Makefile.in (targ-cpu.o): Depend on config.h.
6373 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
6375 * app.c (do_scrub_next_char): Added new state, 9, to avoid
6376 dropping a space immediately following an identifier.
6377 * expr.c, write.c: Rewrote assert expressions to not use multiple
6378 lines; I don't think that can be done portably.
6379 * config/tc-mips.c (macro): Use $AT if target register is zero in
6380 load instruction, which it can be for a floating point load.
6382 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

6393 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
6394 z8k-opc.h, not z8k.h.
6396 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
6399 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

6450 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.

6454 prototypes for all static functions. Moved existing minimal
6455 debugging format support info #ifndef OBJ_ECOFF blocks.

6458 all callers accordingly.
6459 (tc_get_register): Renamed from get_register, and made non-static.
6461 * config/mips-big.mt, config/mips-lit.mt: New files. Define

6504 * make-gas.com: Find obstack.obj if it's not in the current
6506 * read.c (s_ignore): Don't declare is_end_of_line. It's
6507 redundant, and triggers a VMS gcc compiler bug.
6509 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6510 current segment as an argument. (Ignored in all cases but VMS.)
6511 All callers and definitions changed.
6513 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
6515 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
6518 Tue Mar 2 08:53:34 1993 Ken Raeburn (raeburn@cygnus.com)
6520 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,

6527 (obj_elf_xstab): New routine.
6528 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
6529 argument to s_ignore. Put "#if 0" around unused code.
6530 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
6531 Call elf_xstabs for .stabs and .xstabs operators.
6533 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
6535 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
6538 * configure.in: mips-bsd configuration was missing format spec.
6541 * Makefile.in (Makefile): Depends on configure.in.
6543 * config/tc-mips.c (append_insn): Don't check for alignment of
6544 frag in memory; alignment of instructions in section is a separate
6547 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

6553 Tue Mar 2 00:50:43 1993 John Gilmore (gnu@cygnus.com)

6564 * config/tc-sparc.c (s_xword): Now call big_cons, so large
6565 constants are accepted, but symbolic values are not. GCC will not
6566 generate the latter currently.
6568 * frags.c (frag_init): New function.
6569 (zero_address_frag, bss_address_frag): Now initialized at run
6571 * as.c (main): Call frag_init.

6838 * expr.c (operand): If character other than comma or newline is a
6839 logical end-of-line character, use the newline case.

6841 (operand): Set X_add_number field for floating-point numbers.
6842 (operand): Treat zero byte as end-of-operand.
6844 * configure.in (per-target): Look for with_bfd_assembler option.
6845 For now, only accept "no", until the merge is done.
6847 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

6854 * expr.c: Add "const" modifier to hex_value.
6855 * symbols.c: Finish conversion to S_* macros in the VMS only

6857 md_[long,short]_jump_size. Remove declaration of const_flag
6858 (which will be declared in obj-vms.h).
6859 * write.c: Add "const" modifier to md_[long,short]_jump_size.
6860 Fix arguments to VMS_write_object_file.
6861 * config-gas.com: New file. Script for VMS systems to set up the

6869 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
6870 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
6871 types of malformed stabs. Change parsing algorithm so that we are
6872 more certain of having all of the information that we need on hand.
6873 * obj-vms.c (final_forward_reference): New function, used to help
6874 resolve the data types of as many struct elements as possible

6878 * obj-vms.c (VMS_write_object_file): Define all vtable psects
6879 as symbols as well in the object file. Look for external functions

6892 SEG_DATA or SEG_E1 if needed.
6893 (s_lcomm): Likewise with bss_section.
6894 (s_fill): Use memset, not bzero.

6921 mapping to segT enum values.
6922 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
6923 if these are used or defined, if BFD_ASSEMBLER.
6924 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
6925 subseg_new split into two functions.
6926 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
6928 * as.h (volatile): Don't define if already defined.
6929 (had_errors, had_warnings): Provide prototypes for ANSI C even if
6931 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,

6949 * config/te-sco386.h (LOCAL_LABEL): Don't define.
6950 (DOT_LABEL_PREFIX): Define.

6952 name rather than L0\001.
6953 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
6955 * symbols.c, symbols.h (local_bss_counter): Removed.
6956 * write.c (write_object_file): bss no longer uses
6957 local_bss_counter. Pass correct data and bss size to

6964 (size_section): Restored sanity check.
6965 (do_relocs_for): Base section address on s_paddr rather than
6966 computing it. Adjust a29k R_IHIHALF special case to account for

6968 reclos, set s_relptr to 0. Set relocation size in object_headers.
6969 (fill_section): Always set s_vaddr here, removing
6970 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
6971 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
6972 Set STYP_INFO for .comment.
6973 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
6974 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

6976 H_{SET,GET}_* macros.
6977 (do_linenos_for): Set lineno size in object_headers.
6978 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
6979 set s_vaddr here. If string_byte_count remains 4, set it back to
6980 0, and only write strings out if there are some. Call
6981 fill_section before do_relocs_for and do_linenos_for.
6982 (obj_coff_section): Handle optional quoted second argument giving
6983 section characteristics.
6984 (obj_coff_bss): Added to handle .bss.
6985 (obj_coff_ident): Added to handle .ident (puts string in .comment

7011 * config/obj-coff.h: Don't use #elif.
7013 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7014 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7032 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
7034 * listing.c: Call xmalloc, not malloc; don't declare malloc.
7036 * Changes to support SCO 3.2v4:
7037 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
7038 SEG_BSS, fill with NOP_OPCODE.
7039 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
7040 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7041 using ZERO_BASED_SEGMENTS.
7042 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7043 never set segment address for SEG_E2 (.bss) and don't write out
7044 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7045 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7046 definitions, and don't merge tags with non-tags. Check for .bf
7047 rather than just checking whether the second character is b and
7048 the third character is f.
7049 (obj_coff_val): gcc can generate values which we don't handle
7050 correctly; discard information for now, since it only affects the
7051 debugging information.

7053 (yank_symbols): Don't merge labels.
7054 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7056 set segment address if ZERO_BASED_SEGMENTS.
7057 (obj_coff_section): Accept and ignore a trailing quoted string, as
7058 used in AT&T i386 syntax.

7060 relative addends by the segment vaddr.
7061 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
7062 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
7063 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

7164 xrealloc from xrealloc.c.
7165 * xrealloc.c: Deleted.
7166 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
7168 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
7171 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
7173 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

7192 * all files: Whitespace changes for GNU indentation style, done by
7193 GNU `indent'. Some cleanup still needed, especially of comments.
7195 * configure.in: No te-386bsd.h file exists; don't try to use it.

7199 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7200 could be doing emulation.
7202 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7205 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
7208 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
7210 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

7234 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7236 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7237 constant will not fit in an immediate field.
7238 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7260 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
7262 * version.c: Put conditional "const" before version_string, not

7273 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7275 * Support for i386-sysv.
7276 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7280 (fill_section): Don't set STYP_NOLOAD for .bss section.
7281 (fixup_segment): 386 uses strange common symbol format.

7314 * tc-z8k.c: lots of bug fixes
7316 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7318 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7319 #elif, since it is not supported by old compilers.
7320 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7321 couple of expressions in tc-m68k.c.
7323 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7325 * read.c (cons): If NO_RELOC is defined, use it.
7327 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7329 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7331 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7332 local labels to start with a .) and set REGISTER_PREFIX to %.
7333 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7335 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

7342 * messages.c: If __STDC__ is not defined, define NO_STDARG.
7344 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
7346 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7349 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7351 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7352 sections starting from zero, rather than making them consecutive.
7353 This makes subsequent reloc calculations easier, esp if the object
7354 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7355 allocate lcomm in .data rather than in .bss. It seems that some
7356 tools can't cope with a non-zero sized bss before linkage.
7358 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7360 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7361 throughout. That enum no longer means what we thought it meant.

7364 "-mno-688[58]1" options.
7366 * tc-m68k.c: Added CPU32 support.

7374 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
7375 Change LIBDEPS dependence to LIBS.
7377 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
7379 * Makefile.in (install): if $(tooldir) exists, install as in
7382 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7384 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7385 .word is < -32768 or > 32767. The -J flag causes the error to be
7386 ignored. This is to catch over-sized switches generated by gcc on
7387 systems which don't support the broken .word hack.
7388 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7389 write.c (fixup_segment): check for signed .word overflow if
7390 WARN_SIGNED_OVERFLOW_WORD.
7392 * write.c (fixup_segment): fixed missing parens in expression
7393 checking for byte or word overflow.
7395 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
7396 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
7397 WARN_SIGNED_OVERFLOW_WORD.

7405 * obj-coffbfd.h : added stuff
7406 * tc-i386.c (tc_coff_fix2rtype): new function
7407 * tc-i386.h : new coff defines
7409 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7411 * input-scrub.c (input_scrub_push): call input_file_begin, not
7413 messages.c (as_perror): print ": " between the passed in error and
7414 the strerror, like perror does.
7416 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
7418 * Makefile.in: use gas_target instead of modifying target_cpu.
7419 From Steve Chamberlain:
7420 Makefile.in: Handle m68*-*-coff*.
7421 read.c, read.h: add mult argument to s_space
7423 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7424 Motorola and MIT syntax; gas can now assemble either type of
7426 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
7427 From Steve Chamberlain:
7428 m68kcoff.mt: for m68k COFF.
7429 obj-coffbfd.c: (fixup_mdeps) added

7431 (fill_section) added rs_machine_dependent case
7432 (write_object_file) call fixup_mdeps
7433 (fixup_segment) set fx_subsy to 0.
7434 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7436 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
7439 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7441 * Makefile.in (LIBS): Include opcode library.
7443 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
7445 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
7446 including zero are accepted, pass +0.0.

7450 * Makefile.in: map "as" through program_transform_name when
7453 * doc/Makefile.in: map "as" through program_transform_name when
7456 Sat Aug 29 12:11:12 1992 Jim Wilson (wilson@sphagnum.cygnus.com)

7463 tc-i960.c (md_ri_to_chars): Always output bout object file in
7464 little endian byte order (used to use endianness of host).
7466 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7468 * config/tc-m68k.c (init_table): Now const. Always include 68851
7469 data, so that "bc" is available to 68040 cache instructions.
7470 Added "tt0", "tt1", and 68ec030 variants.
7471 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7472 (enum _register): Added TT0, TT1.
7473 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
7474 line number correctly in "internal error" messages. Don't print
7475 architecture-mismatch message for operand errors.
7477 From Colin Smith (colin@wrs.com):
7478 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
7479 than install_operand.
7481 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7483 * listing.c (buffer_line): rewind to the start of include
7484 files, they might be included twice.
7486 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
7488 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
7490 * Makefile.in: defined TARGET_CPU for C code so that it can choose
7491 one element of a family.
7493 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
7495 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
7496 so that we can assemble hand-written libgcc code.
7498 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7500 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
7501 has already been formatted (but may still contain %-characters).
7504 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7506 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7507 written with indirection on the last two operands, which can be
7508 either data or address registers. Added a new operand type 'r'
7509 which accepts either register type. Added '(' to notend stuff in
7510 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
7512 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
7514 * as.h (enum _relax_state): Start off at one, not zero, to better
7515 catch uninitialized-variable errors.

7759 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
7761 * Makefile.in (install): Install into $(tooldir)/bin, since that's
7762 where gcc looks for it.
7764 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
7766 * Makefile.in: Changed some lines to be less confusing for some

7836 * expr.c (operand): if can't work out what sort of operand it is,
7837 then look through FLT_CHARS for a hint.
7839 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
7841 * Makefile.in, configure.in: removed traces of namesubdir,

7845 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
7846 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
7847 copyrights to '92, changed some from Cygnus to FSF.
7849 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7851 * expr.c: If an expression is single comma, then return with
7852 SEG_ABSENT rather than an error - since the sparc front end does
7853 really strange things with things like fbge,a
7855 * as.h: include bfd.h if using many sections
7856 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
7857 local labels didn't work.
7858 * listing.c (list_symbol_table): don't core dump when there's no
7860 * write.c, write.h: call fix_new with the right number of args on
7862 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
7865 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
7867 * app.c: MRI compatibility - allow single quote to start a string.
7868 * as.c: fix typo recently introduced.
7869 * as.h : Don't include aout/reloc.h - it's not right for COFF!
7870 * expr.c: Much rewriting, to accomodate MRI syntax for
7871 expressions. Also easier to read now.
7872 * listing.c: Put back defuns
7873 * read.c: modified to accept MRI syntax, put back listing pseudo
7874 ops so that an assembler built with NO_LISTING ignores list ops
7876 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
7877 machine is a SPARC or a 29K.
7878 * config/obj-aout.c: added s_sect pseudo op
7879 * config/obj-coffbfd.c: lints, set the filehdr flags right and
7880 fill in the timestamp.
7881 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
7882 anymore, define all the relocs which the tc-<x> bit will use so we
7883 can translate from them to the coff types.
7884 * config/tc-a29k.c: reloc_type isn't ane enum any more
7885 * config/tc-m68k.c: Added NO_RELOC definition.
7887 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
7889 * Makefile.in: put header files before C source for TAGS; remove
7890 references to non-existent syscalls.h.
7892 * read.c, write.c subsegs.c: back out the .bss changes.
7894 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
7896 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
7900 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
7902 * symbols.c (local_label_name): symbols now start with ^A.
7904 * read.c, subsegs.c, write.c obj-coff.c: added handling of
7905 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
7906 generate these sections. .align: will use NOP_OPCODE or 0
7907 for padding. This is just for being nice to the
7910 * expr.c (operand): changed to generate local label "\001L0"
7911 starting with a ^A so that it is recognized as a local label.
7913 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
7915 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
7916 i/o opcodes - inb, inw, outb and outw. string manipulation with
7917 att syntax - scmp, slod, smov, ssca, ssto.
7919 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
7920 to just after .file .
7922 In obj_crawl_symbol_chain() where it tries to put the external
7923 symbols apart, with the condition:
7924 (!S_IS_DEFINED(symbolP) &&
7925 !S_IS_DEBUG(symbolP) &&
7926 !SF_GET_STATICS(symbolP))
7927 it was moving too many symbols out. So I switch it back to the
7929 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
7931 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
7932 so that we don't use the F_RELFLG which make the linker complain
7933 that somebody has stripped the relocation info.
7935 Also, the AIX ld program require that the relocation table
7936 is sorted by r_vaddr like the standard ATT assembler does.
7938 [he also changed the sizeof(struct ...)'s into the coff
7939 style FOOSZ macros. I'm not sure this is right, but I can't
7940 remember why. xoxorich.]
7942 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

7951 * configure.in: use the new atof-ns32.c for ns32k.
7953 * write.c: comment change only.
7955 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
7956 aren't yet integrated.
7958 * tc-i860.[hc]: blew off the dust. Something must still be done
7959 about conflicting relocation types.
7961 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
7964 * tc-i960.c, tc-sparc.c: white space and comments only.
7966 * tc-a29k.h: delete duplicate macro definition.
7968 * new file atof-ns32k.c copied from hack's last unreleased gas.
7970 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
7972 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
7975 * nearly everything. flush ChangeLog, package as gas-1.92.1.
7976 ChangeLog's prior to this are sketchy at best. I have logs.
7977 They just aren't ChangeLogs.
7984 version-control: never
