1074 dropping a space immediately following an identifier.
1075 * expr.c, write.c: Rewrote assert expressions to not use multiple
1076 lines; I don't think that can be done portably.
1077 * config/tc-mips.c (macro): Use $AT if target register is zero in
1078 load instruction, which it can be for a floating point load.

1152 prototypes for all static functions. Moved existing minimal
1153 debugging format support info #ifndef OBJ_ECOFF blocks.

1202 * make-gas.com: Find obstack.obj if it's not in the current
1204 * read.c (s_ignore): Don't declare is_end_of_line. It's
1205 redundant, and triggers a VMS gcc compiler bug.
1207 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1208 current segment as an argument. (Ignored in all cases but VMS.)
1209 All callers and definitions changed.

1528 * configure.in (per-target): Look for with_bfd_assembler option.
1529 For now, only accept "no", until the merge is done.
1531 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1532 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1533 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
1534 * read.c: Finish conversion to S_* macros in the VMS only
1535 parts of the program. Add "const" modifier to hex_value.
1536 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
1538 * expr.c: Add "const" modifier to hex_value.
1539 * symbols.c: Finish conversion to S_* macros in the VMS only
1540 parts of the program. Add "const" modifier to
1541 md_[long,short]_jump_size. Remove declaration of const_flag
1542 (which will be declared in obj-vms.h).
1543 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1544 Fix arguments to VMS_write_object_file.
1545 * config-gas.com: New file. Script for VMS systems to set up the
1546 configuration to build gas for VMS, and create config.status.
1547 * make-gas.com: Redone to work with new scheme.
1548 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
1550 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
1551 will swap bytes if needed on a big endian system. Use throughout
1553 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
1554 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1555 types of malformed stabs. Change parsing algorithm so that we are
1556 more certain of having all of the information that we need on hand.
1557 * obj-vms.c (final_forward_reference): New function, used to help
1558 resolve the data types of as many struct elements as possible
1559 when some part of the struct is not fully defined by the compiler.
1560 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
1562 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1563 as symbols as well in the object file. Look for external functions
1564 that start with "__vt.", and turn them into variables, since the
1565 g++ compiler is incapable of doing this.
1566 * tc-vax.c: Add '1' option for backward compatibility with older GCC
1568 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
1569 * input-scrub.c (as_where): Fix bug where as would crash if we did not
1570 have the name of the source file yet.
1571 * config/ho-vms.h: define HO_VMS, not HO_VAX.
1573 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
1575 * read.c (s_data): Always use "data_section", since it'll map to
1576 SEG_DATA or SEG_E1 if needed.
1577 (s_lcomm): Likewise with bss_section.
1578 (s_fill): Use memset, not bzero.
1580 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

1596 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
1597 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

1601 (section_alignment): Declare only if not BFD_ASSEMBLER.
1602 (big_section, reg_section, pass1_section, diff_section,
1603 absent_section, text_section, data_section, bss_section): If
1604 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
1605 mapping to segT enum values.
1606 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1607 if these are used or defined, if BFD_ASSEMBLER.
1608 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
1609 subseg_new split into two functions.
1610 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
1612 * as.h (volatile): Don't define if already defined.
1613 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1615 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1616 declare with format attribute for -Wformat checking.
1618 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
1620 * app.c, config/tc-*.c: Don't include read.h, since it is already
1623 * These are based on patches from Minh Tran-le
1624 <mtranle@paris.intellicorp.com>.
1625 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1626 obj_format coffbfd and gas_target i386coff for target.
1627 (i[34]86-*-isc*): New host (uses sysv).
1628 * config/i386aix.mt: Removed (no longer used).
1629 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
1631 (LDFLAGS): Added, defined as -shlib.
1632 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1633 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1634 (DOT_LABEL_PREFIX): Define.
1635 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1636 name rather than L0\001.
1637 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
1639 * symbols.c, symbols.h (local_bss_counter): Removed.
1640 * write.c (write_object_file): bss no longer uses
1641 local_bss_counter. Pass correct data and bss size to
1642 VMS_write_object_file.

1647 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
1648 (size_section): Restored sanity check.
1649 (do_relocs_for): Base section address on s_paddr rather than
1650 computing it. Adjust a29k R_IHIHALF special case to account for
1651 section paddr (used to require paddr to be zero). If there are no
1652 reclos, set s_relptr to 0. Set relocation size in object_headers.
1653 (fill_section): Always set s_vaddr here, removing
1654 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
1655 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
1656 Set STYP_INFO for .comment.
1657 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
1658 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

1660 H_{SET,GET}_* macros.
1661 (do_linenos_for): Set lineno size in object_headers.
1662 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
1663 set s_vaddr here. If string_byte_count remains 4, set it back to
1664 0, and only write strings out if there are some. Call
1665 fill_section before do_relocs_for and do_linenos_for.
1666 (obj_coff_section): Handle optional quoted second argument giving
1667 section characteristics.
1668 (obj_coff_bss): Added to handle .bss.
1669 (obj_coff_ident): Added to handle .ident (puts string in .comment

1689 (do_scrub_next_char): For \", return " not '.
1690 (symbol_chars): Now const.
1692 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
1693 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
1695 * config/obj-coff.h: Don't use #elif.
1697 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
1698 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

1724 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
1725 using ZERO_BASED_SEGMENTS.
1726 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
1727 never set segment address for SEG_E2 (.bss) and don't write out
1728 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
1729 (obj_coff_endef): Don't merge labels or symbols awaiting forward
1730 definitions, and don't merge tags with non-tags. Check for .bf
1731 rather than just checking whether the second character is b and
1732 the third character is f.
1733 (obj_coff_val): gcc can generate values which we don't handle
1734 correctly; discard information for now, since it only affects the
1735 debugging information.

1737 (yank_symbols): Don't merge labels.
1738 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2000 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2002 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2003 #elif, since it is not supported by old compilers.
2004 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2005 couple of expressions in tc-m68k.c.
2007 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2009 * read.c (cons): If NO_RELOC is defined, use it.
2011 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2013 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2015 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2016 local labels to start with a .) and set REGISTER_PREFIX to %.
2017 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2019 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

2035 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2036 sections starting from zero, rather than making them consecutive.
2037 This makes subsequent reloc calculations easier, esp if the object
2038 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2039 allocate lcomm in .data rather than in .bss. It seems that some
2040 tools can't cope with a non-zero sized bss before linkage.
2042 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2044 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2045 throughout. That enum no longer means what we thought it meant.

2048 "-mno-688[58]1" options.
2050 * tc-m68k.c: Added CPU32 support.

2063 * Makefile.in (install): if $(tooldir) exists, install as in
2066 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2068 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2069 .word is < -32768 or > 32767. The -J flag causes the error to be
2070 ignored. This is to catch over-sized switches generated by gcc on
2071 systems which don't support the broken .word hack.
2072 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2073 write.c (fixup_segment): check for signed .word overflow if
2074 WARN_SIGNED_OVERFLOW_WORD.
2076 * write.c (fixup_segment): fixed missing parens in expression
2077 checking for byte or word overflow.
2079 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

2093 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2095 * input-scrub.c (input_scrub_push): call input_file_begin, not
2097 messages.c (as_perror): print ": " between the passed in error and
2098 the strerror, like perror does.
2100 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

2103 From Steve Chamberlain:
2104 Makefile.in: Handle m68*-*-coff*.
2105 read.c, read.h: add mult argument to s_space
2107 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2108 Motorola and MIT syntax; gas can now assemble either type of
2110 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

2117 (fixup_segment) set fx_subsy to 0.
2118 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2120 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
2123 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2125 * Makefile.in (LIBS): Include opcode library.

2152 * config/tc-m68k.c (init_table): Now const. Always include 68851
2153 data, so that "bc" is available to 68040 cache instructions.
2154 Added "tt0", "tt1", and 68ec030 variants.
2155 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2156 (enum _register): Added TT0, TT1.
2157 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2158 line number correctly in "internal error" messages. Don't print
2159 architecture-mismatch message for operand errors.
2161 From Colin Smith (colin@wrs.com):
2162 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

2184 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2185 has already been formatted (but may still contain %-characters).
2188 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2190 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2191 written with indirection on the last two operands, which can be
2192 either data or address registers. Added a new operand type 'r'
2193 which accepts either register type. Added '(' to notend stuff in
2194 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2492 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2494 * doc/Makefile.in: commented out line for building as-all.texinfo.
2497 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
2499 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
2501 * Makefile.in: added check target.
2503 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2505 * Makefile.in: added tooldir and program_prefix.
2507 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
2509 * write.{c,h} (fix_new): Make these declarations consistent.
2511 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
2513 * Makefile.in (strerror.o): Add rule so that broken Sun make can
2516 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
2518 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
2520 * expr.c (operand): if can't work out what sort of operand it is,
2521 then look through FLT_CHARS for a hint.
2523 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
2525 * Makefile.in, configure.in: removed traces of namesubdir,
2526 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2527 copyrights to '92, changed some from Cygnus to FSF.
2529 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
2530 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2531 copyrights to '92, changed some from Cygnus to FSF.
2533 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2535 * expr.c: If an expression is single comma, then return with
2536 SEG_ABSENT rather than an error - since the sparc front end does
2537 really strange things with things like fbge,a
2539 * as.h: include bfd.h if using many sections
2540 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2541 local labels didn't work.
2542 * listing.c (list_symbol_table): don't core dump when there's no
2544 * write.c, write.h: call fix_new with the right number of args on
2546 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2549 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2551 * app.c: MRI compatibility - allow single quote to start a string.
2552 * as.c: fix typo recently introduced.
2553 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2554 * expr.c: Much rewriting, to accomodate MRI syntax for
2555 expressions. Also easier to read now.
2556 * listing.c: Put back defuns
2557 * read.c: modified to accept MRI syntax, put back listing pseudo
2558 ops so that an assembler built with NO_LISTING ignores list ops
2560 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2561 machine is a SPARC or a 29K.
2562 * config/obj-aout.c: added s_sect pseudo op
2563 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2564 fill in the timestamp.
2565 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2566 anymore, define all the relocs which the tc-<x> bit will use so we
2567 can translate from them to the coff types.
2568 * config/tc-a29k.c: reloc_type isn't ane enum any more
2569 * config/tc-m68k.c: Added NO_RELOC definition.
2571 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2573 * Makefile.in: put header files before C source for TAGS; remove
2574 references to non-existent syscalls.h.
2576 * read.c, write.c subsegs.c: back out the .bss changes.
2578 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2580 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2584 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2586 * symbols.c (local_label_name): symbols now start with ^A.
2588 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2589 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2590 generate these sections. .align: will use NOP_OPCODE or 0
2591 for padding. This is just for being nice to the
2594 * expr.c (operand): changed to generate local label "\001L0"
2595 starting with a ^A so that it is recognized as a local label.
2597 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2599 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2600 i/o opcodes - inb, inw, outb and outw. string manipulation with
2601 att syntax - scmp, slod, smov, ssca, ssto.
2603 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2604 to just after .file .
2606 In obj_crawl_symbol_chain() where it tries to put the external
2607 symbols apart, with the condition:
2608 (!S_IS_DEFINED(symbolP) &&
2609 !S_IS_DEBUG(symbolP) &&
2610 !SF_GET_STATICS(symbolP))
2611 it was moving too many symbols out. So I switch it back to the
2613 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2615 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2616 so that we don't use the F_RELFLG which make the linker complain
2617 that somebody has stripped the relocation info.
2619 Also, the AIX ld program require that the relocation table
2620 is sorted by r_vaddr like the standard ATT assembler does.
2622 [he also changed the sizeof(struct ...)'s into the coff
2623 style FOOSZ macros. I'm not sure this is right, but I can't
2624 remember why. xoxorich.]
2626 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
2628 * Makefile.in, configure.in, doc: use the doc. Build it, install
2631 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2633 * read.c: white space and comments only.
2635 * configure.in: use the new atof-ns32.c for ns32k.
2637 * write.c: comment change only.
2639 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2640 aren't yet integrated.
2642 * tc-i860.[hc]: blew off the dust. Something must still be done
2643 about conflicting relocation types.
2645 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2648 * tc-i960.c, tc-sparc.c: white space and comments only.
2650 * tc-a29k.h: delete duplicate macro definition.
2652 * new file atof-ns32k.c copied from hack's last unreleased gas.
2654 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
2656 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
2659 * nearly everything. flush ChangeLog, package as gas-1.92.1.
2660 ChangeLog's prior to this are sketchy at best. I have logs.
2661 They just aren't ChangeLogs.
