1105 dropping a space immediately following an identifier.
1106 * expr.c, write.c: Rewrote assert expressions to not use multiple
1107 lines; I don't think that can be done portably.
1108 * config/tc-mips.c (macro): Use $AT if target register is zero in
1109 load instruction, which it can be for a floating point load.

1235 * read.c (s_ignore): Don't declare is_end_of_line. It's
1236 redundant, and triggers a VMS gcc compiler bug.
1238 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1239 current segment as an argument. (Ignored in all cases but VMS.)
1240 All callers and definitions changed.

1532 offset field is set.
1534 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
1536 * config/tc-sparc.c (architecture_requested, warn_on_bump,
1537 md_relax_table): Use default zero initialization.
1538 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
1539 latter, instead of selecting with preprocessor conditionals.
1541 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1543 * configure.in: recognise all sparclite variants
1545 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
1547 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
1548 accidentally changed to use subseg_change where it should have
1551 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
1553 * expr.c (operand): If character other than comma or newline is a
1554 logical end-of-line character, use the newline case.
1555 From Eric Youngdale:
1556 (operand): Set X_add_number field for floating-point numbers.
1557 (operand): Treat zero byte as end-of-operand.
1559 * configure.in (per-target): Look for with_bfd_assembler option.
1560 For now, only accept "no", until the merge is done.
1562 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1563 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1564 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1565 * read.c: Finish conversion to S_* macros in the VMS only
1566 parts of the program. Add "const" modifier to hex_value.
1567 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
1569 * expr.c: Add "const" modifier to hex_value.
1570 * symbols.c: Finish conversion to S_* macros in the VMS only
1571 parts of the program. Add "const" modifier to
1572 md_[long,short]_jump_size. Remove declaration of const_flag
1573 (which will be declared in obj-vms.h).
1574 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1575 Fix arguments to VMS_write_object_file.
1576 * config-gas.com: New file. Script for VMS systems to set up the
1577 configuration to build gas for VMS, and create config.status.
1578 * make-gas.com: Redone to work with new scheme.
1579 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
1581 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
1582 will swap bytes if needed on a big endian system. Use throughout
1584 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
1585 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1586 types of malformed stabs. Change parsing algorithm so that we are
1587 more certain of having all of the information that we need on hand.
1588 * obj-vms.c (final_forward_reference): New function, used to help
1589 resolve the data types of as many struct elements as possible
1590 when some part of the struct is not fully defined by the compiler.
1591 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
1593 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1594 as symbols as well in the object file. Look for external functions
1595 that start with "__vt.", and turn them into variables, since the
1596 g++ compiler is incapable of doing this.
1597 * tc-vax.c: Add '1' option for backward compatibility with older GCC
1599 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
1600 * input-scrub.c (as_where): Fix bug where as would crash if we did not
1601 have the name of the source file yet.
1602 * config/ho-vms.h: define HO_VMS, not HO_VAX.
1604 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
1606 * read.c (s_data): Always use "data_section", since it'll map to
1607 SEG_DATA or SEG_E1 if needed.
1608 (s_lcomm): Likewise with bss_section.
1609 (s_fill): Use memset, not bzero.
1611 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
1613 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

1627 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
1628 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

1632 (section_alignment): Declare only if not BFD_ASSEMBLER.
1633 (big_section, reg_section, pass1_section, diff_section,
1634 absent_section, text_section, data_section, bss_section): If
1635 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
1636 mapping to segT enum values.
1637 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1638 if these are used or defined, if BFD_ASSEMBLER.
1639 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
1640 subseg_new split into two functions.
1641 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
1643 * as.h (volatile): Don't define if already defined.
1644 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1646 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1647 declare with format attribute for -Wformat checking.
1649 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
1651 * app.c, config/tc-*.c: Don't include read.h, since it is already
1654 * These are based on patches from Minh Tran-le
1655 <mtranle@paris.intellicorp.com>.
1656 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1657 obj_format coffbfd and gas_target i386coff for target.
1658 (i[34]86-*-isc*): New host (uses sysv).
1659 * config/i386aix.mt: Removed (no longer used).
1660 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
1662 (LDFLAGS): Added, defined as -shlib.
1663 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1664 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1665 (DOT_LABEL_PREFIX): Define.
1666 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1667 name rather than L0\001.
1668 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
1670 * symbols.c, symbols.h (local_bss_counter): Removed.
1671 * write.c (write_object_file): bss no longer uses
1672 local_bss_counter. Pass correct data and bss size to
1673 VMS_write_object_file.

1678 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
1679 (size_section): Restored sanity check.
1680 (do_relocs_for): Base section address on s_paddr rather than
1681 computing it. Adjust a29k R_IHIHALF special case to account for
1682 section paddr (used to require paddr to be zero). If there are no
1683 reclos, set s_relptr to 0. Set relocation size in object_headers.
1684 (fill_section): Always set s_vaddr here, removing
1685 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
1686 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
1687 Set STYP_INFO for .comment.
1688 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
1689 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

1691 H_{SET,GET}_* macros.
1692 (do_linenos_for): Set lineno size in object_headers.
1693 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
1694 set s_vaddr here. If string_byte_count remains 4, set it back to
1695 0, and only write strings out if there are some. Call
1696 fill_section before do_relocs_for and do_linenos_for.
1697 (obj_coff_section): Handle optional quoted second argument giving
1698 section characteristics.
1699 (obj_coff_bss): Added to handle .bss.
1700 (obj_coff_ident): Added to handle .ident (puts string in .comment

1703 (fixup_mdeps): Change to segment. Call frag_wane after
1705 (fixup_segment): Explicitly check S_IS_COMMON before making 386
1706 adjustment (already happened only for common symbols, but this is
1708 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
1709 * config/tc-i386.c (s_bss): Don't use if I386COFF.

1720 (do_scrub_next_char): For \", return " not '.
1721 (symbol_chars): Now const.
1723 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
1724 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
1726 * config/obj-coff.h: Don't use #elif.
1728 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
1729 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
1731 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

1755 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
1756 using ZERO_BASED_SEGMENTS.
1757 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
1758 never set segment address for SEG_E2 (.bss) and don't write out
1759 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
1760 (obj_coff_endef): Don't merge labels or symbols awaiting forward
1761 definitions, and don't merge tags with non-tags. Check for .bf
1762 rather than just checking whether the second character is b and
1763 the third character is f.
1764 (obj_coff_val): gcc can generate values which we don't handle
1765 correctly; discard information for now, since it only affects the
1766 debugging information.
1767 (tag_find_or_name): Don't insert tags in the symbol table.
1768 (yank_symbols): Don't merge labels.
1769 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2013 part of the symbol for the symbol name
2015 * tc-m68k.c (get_num): make it work for all segments, not just the
2018 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

2033 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2034 #elif, since it is not supported by old compilers.
2035 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2036 couple of expressions in tc-m68k.c.
2038 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2040 * read.c (cons): If NO_RELOC is defined, use it.
2042 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2044 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2046 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2047 local labels to start with a .) and set REGISTER_PREFIX to %.
2048 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

2066 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2067 sections starting from zero, rather than making them consecutive.
2068 This makes subsequent reloc calculations easier, esp if the object
2069 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2070 allocate lcomm in .data rather than in .bss. It seems that some
2071 tools can't cope with a non-zero sized bss before linkage.
2073 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2075 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

2097 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2099 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2100 .word is < -32768 or > 32767. The -J flag causes the error to be
2101 ignored. This is to catch over-sized switches generated by gcc on
2102 systems which don't support the broken .word hack.
2103 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2104 write.c (fixup_segment): check for signed .word overflow if
2105 WARN_SIGNED_OVERFLOW_WORD.

2124 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2126 * input-scrub.c (input_scrub_push): call input_file_begin, not
2128 messages.c (as_perror): print ": " between the passed in error and
2129 the strerror, like perror does.

2134 From Steve Chamberlain:
2135 Makefile.in: Handle m68*-*-coff*.
2136 read.c, read.h: add mult argument to s_space
2138 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2139 Motorola and MIT syntax; gas can now assemble either type of
2141 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2148 (fixup_segment) set fx_subsy to 0.
2149 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2151 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2154 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2156 * Makefile.in (LIBS): Include opcode library.

2183 * config/tc-m68k.c (init_table): Now const. Always include 68851
2184 data, so that "bc" is available to 68040 cache instructions.
2185 Added "tt0", "tt1", and 68ec030 variants.
2186 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2187 (enum _register): Added TT0, TT1.
2188 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2189 line number correctly in "internal error" messages. Don't print
2190 architecture-mismatch message for operand errors.

2215 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2216 has already been formatted (but may still contain %-characters).
2219 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2221 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2222 written with indirection on the last two operands, which can be
2223 either data or address registers. Added a new operand type 'r'
2224 which accepts either register type. Added '(' to notend stuff in
2225 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2489 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
2491 * symbols.c (fb_label_init): fix sizeof to memset.
2493 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
2495 * Makefile.in: install the man page.
2497 * Makefile.in: pass down MAKEINFO explicitly on info.
2499 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
2501 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2503 * flonum-const.c: renamed flonum-konst.c to stop dos name
2506 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
2508 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
2509 tc-m68k.h to te-sun3.h.
2511 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
2513 * configure.in: vxworks68 gets te-sun3.h.
2515 * expr.c: remove limitation that local_labels_dollar or
2516 local_labels_fb must be < 10.
2518 * symbols.c: remove local_labels_dollar, replace with a function
2519 interface for a sparse array. All users adjusted.
2521 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
2523 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2525 * doc/Makefile.in: commented out line for building as-all.texinfo.
2528 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
2530 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
2532 * Makefile.in: added check target.
2534 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2536 * Makefile.in: added tooldir and program_prefix.
2538 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
2540 * write.{c,h} (fix_new): Make these declarations consistent.
2542 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
2544 * Makefile.in (strerror.o): Add rule so that broken Sun make can
2547 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
2549 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
2551 * expr.c (operand): if can't work out what sort of operand it is,
2552 then look through FLT_CHARS for a hint.
2554 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
2556 * Makefile.in, configure.in: removed traces of namesubdir,
2557 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2558 copyrights to '92, changed some from Cygnus to FSF.
2560 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
2561 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2562 copyrights to '92, changed some from Cygnus to FSF.
2564 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2566 * expr.c: If an expression is single comma, then return with
2567 SEG_ABSENT rather than an error - since the sparc front end does
2568 really strange things with things like fbge,a
2570 * as.h: include bfd.h if using many sections
2571 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2572 local labels didn't work.
2573 * listing.c (list_symbol_table): don't core dump when there's no
2575 * write.c, write.h: call fix_new with the right number of args on
2577 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2580 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2582 * app.c: MRI compatibility - allow single quote to start a string.
2583 * as.c: fix typo recently introduced.
2584 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2585 * expr.c: Much rewriting, to accomodate MRI syntax for
2586 expressions. Also easier to read now.
2587 * listing.c: Put back defuns
2588 * read.c: modified to accept MRI syntax, put back listing pseudo
2589 ops so that an assembler built with NO_LISTING ignores list ops
2591 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2592 machine is a SPARC or a 29K.
2593 * config/obj-aout.c: added s_sect pseudo op
2594 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2595 fill in the timestamp.
2596 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2597 anymore, define all the relocs which the tc-<x> bit will use so we
2598 can translate from them to the coff types.
2599 * config/tc-a29k.c: reloc_type isn't ane enum any more
2600 * config/tc-m68k.c: Added NO_RELOC definition.
2602 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2604 * Makefile.in: put header files before C source for TAGS; remove
2605 references to non-existent syscalls.h.
2607 * read.c, write.c subsegs.c: back out the .bss changes.
2609 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2611 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2615 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2617 * symbols.c (local_label_name): symbols now start with ^A.
2619 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2620 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2621 generate these sections. .align: will use NOP_OPCODE or 0
2622 for padding. This is just for being nice to the
2625 * expr.c (operand): changed to generate local label "\001L0"
2626 starting with a ^A so that it is recognized as a local label.
2628 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2630 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2631 i/o opcodes - inb, inw, outb and outw. string manipulation with
2632 att syntax - scmp, slod, smov, ssca, ssto.
2634 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2635 to just after .file .
2637 In obj_crawl_symbol_chain() where it tries to put the external
2638 symbols apart, with the condition:
2639 (!S_IS_DEFINED(symbolP) &&
2640 !S_IS_DEBUG(symbolP) &&
2641 !SF_GET_STATICS(symbolP))
2642 it was moving too many symbols out. So I switch it back to the
2644 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2646 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2647 so that we don't use the F_RELFLG which make the linker complain
2648 that somebody has stripped the relocation info.
2650 Also, the AIX ld program require that the relocation table
2651 is sorted by r_vaddr like the standard ATT assembler does.
2653 [he also changed the sizeof(struct ...)'s into the coff
2654 style FOOSZ macros. I'm not sure this is right, but I can't
2655 remember why. xoxorich.]
2657 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
2659 * Makefile.in, configure.in, doc: use the doc. Build it, install
2662 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2664 * read.c: white space and comments only.
2666 * configure.in: use the new atof-ns32.c for ns32k.
2668 * write.c: comment change only.
2670 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2671 aren't yet integrated.
2673 * tc-i860.[hc]: blew off the dust. Something must still be done
2674 about conflicting relocation types.
2676 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2679 * tc-i960.c, tc-sparc.c: white space and comments only.
2681 * tc-a29k.h: delete duplicate macro definition.
2683 * new file atof-ns32k.c copied from hack's last unreleased gas.
2685 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
2687 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
2690 * nearly everything. flush ChangeLog, package as gas-1.92.1.
2691 ChangeLog's prior to this are sketchy at best. I have logs.
2692 They just aren't ChangeLogs.
