1065 dropping a space immediately following an identifier.
1066 * expr.c, write.c: Rewrote assert expressions to not use multiple
1067 lines; I don't think that can be done portably.
1068 * config/tc-mips.c (macro): Use $AT if target register is zero in
1069 load instruction, which it can be for a floating point load.

1195 * read.c (s_ignore): Don't declare is_end_of_line. It's
1196 redundant, and triggers a VMS gcc compiler bug.
1198 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1199 current segment as an argument. (Ignored in all cases but VMS.)
1200 All callers and definitions changed.

1529 * expr.c: Add "const" modifier to hex_value.
1530 * symbols.c: Finish conversion to S_* macros in the VMS only
1531 parts of the program. Add "const" modifier to
1532 md_[long,short]_jump_size. Remove declaration of const_flag
1533 (which will be declared in obj-vms.h).
1534 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1535 Fix arguments to VMS_write_object_file.
1536 * config-gas.com: New file. Script for VMS systems to set up the
1537 configuration to build gas for VMS, and create config.status.
1538 * make-gas.com: Redone to work with new scheme.
1539 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
1541 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
1542 will swap bytes if needed on a big endian system. Use throughout
1544 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
1545 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1546 types of malformed stabs. Change parsing algorithm so that we are
1547 more certain of having all of the information that we need on hand.
1548 * obj-vms.c (final_forward_reference): New function, used to help
1549 resolve the data types of as many struct elements as possible

1553 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1554 as symbols as well in the object file. Look for external functions
1555 that start with "__vt.", and turn them into variables, since the
1556 g++ compiler is incapable of doing this.
1557 * tc-vax.c: Add '1' option for backward compatibility with older GCC
1559 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
1560 * input-scrub.c (as_where): Fix bug where as would crash if we did not
1561 have the name of the source file yet.

1564 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
1566 * read.c (s_data): Always use "data_section", since it'll map to
1567 SEG_DATA or SEG_E1 if needed.
1568 (s_lcomm): Likewise with bss_section.
1569 (s_fill): Use memset, not bzero.
1571 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

1593 (big_section, reg_section, pass1_section, diff_section,
1594 absent_section, text_section, data_section, bss_section): If
1595 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
1596 mapping to segT enum values.
1597 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1598 if these are used or defined, if BFD_ASSEMBLER.
1599 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
1600 subseg_new split into two functions.
1601 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
1603 * as.h (volatile): Don't define if already defined.
1604 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1606 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1607 declare with format attribute for -Wformat checking.
1609 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
1611 * app.c, config/tc-*.c: Don't include read.h, since it is already
1614 * These are based on patches from Minh Tran-le
1615 <mtranle@paris.intellicorp.com>.
1616 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1617 obj_format coffbfd and gas_target i386coff for target.
1618 (i[34]86-*-isc*): New host (uses sysv).
1619 * config/i386aix.mt: Removed (no longer used).
1620 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
1622 (LDFLAGS): Added, defined as -shlib.
1623 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1624 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1625 (DOT_LABEL_PREFIX): Define.
1626 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1627 name rather than L0\001.
1628 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
1630 * symbols.c, symbols.h (local_bss_counter): Removed.

1639 (size_section): Restored sanity check.
1640 (do_relocs_for): Base section address on s_paddr rather than
1641 computing it. Adjust a29k R_IHIHALF special case to account for
1642 section paddr (used to require paddr to be zero). If there are no
1643 reclos, set s_relptr to 0. Set relocation size in object_headers.
1644 (fill_section): Always set s_vaddr here, removing
1645 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
1646 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
1647 Set STYP_INFO for .comment.

1651 H_{SET,GET}_* macros.
1652 (do_linenos_for): Set lineno size in object_headers.
1653 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
1654 set s_vaddr here. If string_byte_count remains 4, set it back to
1655 0, and only write strings out if there are some. Call
1656 fill_section before do_relocs_for and do_linenos_for.
1657 (obj_coff_section): Handle optional quoted second argument giving
1658 section characteristics.
1659 (obj_coff_bss): Added to handle .bss.

1680 (do_scrub_next_char): For \", return " not '.
1681 (symbol_chars): Now const.
1683 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
1684 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
1686 * config/obj-coff.h: Don't use #elif.
1688 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
1689 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

1718 never set segment address for SEG_E2 (.bss) and don't write out
1719 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
1720 (obj_coff_endef): Don't merge labels or symbols awaiting forward
1721 definitions, and don't merge tags with non-tags. Check for .bf
1722 rather than just checking whether the second character is b and
1723 the third character is f.
1724 (obj_coff_val): gcc can generate values which we don't handle
1725 correctly; discard information for now, since it only affects the
1726 debugging information.

1728 (yank_symbols): Don't merge labels.
1729 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

1996 couple of expressions in tc-m68k.c.
1998 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2000 * read.c (cons): If NO_RELOC is defined, use it.

2004 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2006 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2007 local labels to start with a .) and set REGISTER_PREFIX to %.
2008 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

2026 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2027 sections starting from zero, rather than making them consecutive.
2028 This makes subsequent reloc calculations easier, esp if the object
2029 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2030 allocate lcomm in .data rather than in .bss. It seems that some
2031 tools can't cope with a non-zero sized bss before linkage.

2059 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2060 .word is < -32768 or > 32767. The -J flag causes the error to be
2061 ignored. This is to catch over-sized switches generated by gcc on
2062 systems which don't support the broken .word hack.
2063 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2064 write.c (fixup_segment): check for signed .word overflow if
2065 WARN_SIGNED_OVERFLOW_WORD.

2143 * config/tc-m68k.c (init_table): Now const. Always include 68851
2144 data, so that "bc" is available to 68040 cache instructions.
2145 Added "tt0", "tt1", and 68ec030 variants.
2146 (md_assemble): Complain if 68000 (only) and 68881 are specified.
2147 (enum _register): Added TT0, TT1.
2148 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
2149 line number correctly in "internal error" messages. Don't print
2150 architecture-mismatch message for operand errors.

2175 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2176 has already been formatted (but may still contain %-characters).
2179 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
2181 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2182 written with indirection on the last two operands, which can be
2183 either data or address registers. Added a new operand type 'r'
2184 which accepts either register type. Added '(' to notend stuff in
2185 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2494 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2496 * Makefile.in: added tooldir and program_prefix.
2498 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
2500 * write.{c,h} (fix_new): Make these declarations consistent.
2502 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
2504 * Makefile.in (strerror.o): Add rule so that broken Sun make can
2507 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
2509 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
2511 * expr.c (operand): if can't work out what sort of operand it is,
2512 then look through FLT_CHARS for a hint.
2514 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
2516 * Makefile.in, configure.in: removed traces of namesubdir,
2517 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2518 copyrights to '92, changed some from Cygnus to FSF.
2520 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
2521 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2522 copyrights to '92, changed some from Cygnus to FSF.
2524 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2526 * expr.c: If an expression is single comma, then return with
2527 SEG_ABSENT rather than an error - since the sparc front end does
2528 really strange things with things like fbge,a
2530 * as.h: include bfd.h if using many sections
2531 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2532 local labels didn't work.
2533 * listing.c (list_symbol_table): don't core dump when there's no
2535 * write.c, write.h: call fix_new with the right number of args on
2537 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2540 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2542 * app.c: MRI compatibility - allow single quote to start a string.
2543 * as.c: fix typo recently introduced.
2544 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2545 * expr.c: Much rewriting, to accomodate MRI syntax for
2546 expressions. Also easier to read now.
2547 * listing.c: Put back defuns
2548 * read.c: modified to accept MRI syntax, put back listing pseudo
2549 ops so that an assembler built with NO_LISTING ignores list ops
2551 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2552 machine is a SPARC or a 29K.
2553 * config/obj-aout.c: added s_sect pseudo op
2554 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2555 fill in the timestamp.
2556 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2557 anymore, define all the relocs which the tc-<x> bit will use so we
2558 can translate from them to the coff types.
2559 * config/tc-a29k.c: reloc_type isn't ane enum any more
2560 * config/tc-m68k.c: Added NO_RELOC definition.
2562 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2564 * Makefile.in: put header files before C source for TAGS; remove
2565 references to non-existent syscalls.h.
2567 * read.c, write.c subsegs.c: back out the .bss changes.
2569 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2571 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2575 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2577 * symbols.c (local_label_name): symbols now start with ^A.
2579 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2580 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2581 generate these sections. .align: will use NOP_OPCODE or 0
2582 for padding. This is just for being nice to the
2585 * expr.c (operand): changed to generate local label "\001L0"
2586 starting with a ^A so that it is recognized as a local label.
2588 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2590 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2591 i/o opcodes - inb, inw, outb and outw. string manipulation with
2592 att syntax - scmp, slod, smov, ssca, ssto.
2594 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2595 to just after .file .
2597 In obj_crawl_symbol_chain() where it tries to put the external
2598 symbols apart, with the condition:
2599 (!S_IS_DEFINED(symbolP) &&
2600 !S_IS_DEBUG(symbolP) &&
2601 !SF_GET_STATICS(symbolP))
2602 it was moving too many symbols out. So I switch it back to the
2604 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2606 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2607 so that we don't use the F_RELFLG which make the linker complain
2608 that somebody has stripped the relocation info.
2610 Also, the AIX ld program require that the relocation table
2611 is sorted by r_vaddr like the standard ATT assembler does.
2613 [he also changed the sizeof(struct ...)'s into the coff
2614 style FOOSZ macros. I'm not sure this is right, but I can't
2615 remember why. xoxorich.]
2617 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
2619 * Makefile.in, configure.in, doc: use the doc. Build it, install
2622 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2624 * read.c: white space and comments only.
2626 * configure.in: use the new atof-ns32.c for ns32k.
2628 * write.c: comment change only.
2630 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2631 aren't yet integrated.
2633 * tc-i860.[hc]: blew off the dust. Something must still be done
2634 about conflicting relocation types.
2636 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2639 * tc-i960.c, tc-sparc.c: white space and comments only.
2641 * tc-a29k.h: delete duplicate macro definition.
2643 * new file atof-ns32k.c copied from hack's last unreleased gas.
2645 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
2647 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
2650 * nearly everything. flush ChangeLog, package as gas-1.92.1.
2651 ChangeLog's prior to this are sketchy at best. I have logs.
2652 They just aren't ChangeLogs.
