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

516 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
518 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
519 will swap bytes if needed on a big endian system. Use throughout
521 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
522 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
523 types of malformed stabs. Change parsing algorithm so that we are
524 more certain of having all of the information that we need on hand.
525 * obj-vms.c (final_forward_reference): New function, used to help
526 resolve the data types of as many struct elements as possible
527 when some part of the struct is not fully defined by the compiler.
528 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
530 * obj-vms.c (VMS_write_object_file): Define all vtable psects
531 as symbols as well in the object file. Look for external functions
532 that start with "__vt.", and turn them into variables, since the
533 g++ compiler is incapable of doing this.
534 * tc-vax.c: Add '1' option for backward compatibility with older GCC
536 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
537 * input-scrub.c (as_where): Fix bug where as would crash if we did not
538 have the name of the source file yet.
539 * config/ho-vms.h: define HO_VMS, not HO_VAX.
541 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
543 * read.c (s_data): Always use "data_section", since it'll map to
544 SEG_DATA or SEG_E1 if needed.
545 (s_lcomm): Likewise with bss_section.
546 (s_fill): Use memset, not bzero.
548 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

569 (section_alignment): Declare only if not BFD_ASSEMBLER.
570 (big_section, reg_section, pass1_section, diff_section,
571 absent_section, text_section, data_section, bss_section): If
572 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
573 mapping to segT enum values.
574 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
575 if these are used or defined, if BFD_ASSEMBLER.
576 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
577 subseg_new split into two functions.
578 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
580 * as.h (volatile): Don't define if already defined.
581 (had_errors, had_warnings): Provide prototypes for ANSI C even if
583 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
584 declare with format attribute for -Wformat checking.
586 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
588 * app.c, config/tc-*.c: Don't include read.h, since it is already
591 * These are based on patches from Minh Tran-le
592 <mtranle@paris.intellicorp.com>.
593 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
594 obj_format coffbfd and gas_target i386coff for target.
595 (i[34]86-*-isc*): New host (uses sysv).
596 * config/i386aix.mt: Removed (no longer used).
597 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
599 (LDFLAGS): Added, defined as -shlib.
600 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
601 * config/te-sco386.h (LOCAL_LABEL): Don't define.
602 (DOT_LABEL_PREFIX): Define.
603 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
604 name rather than L0\001.
605 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
607 * symbols.c, symbols.h (local_bss_counter): Removed.
608 * write.c (write_object_file): bss no longer uses

615 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
616 (size_section): Restored sanity check.
617 (do_relocs_for): Base section address on s_paddr rather than
618 computing it. Adjust a29k R_IHIHALF special case to account for
619 section paddr (used to require paddr to be zero). If there are no
620 reclos, set s_relptr to 0. Set relocation size in object_headers.
621 (fill_section): Always set s_vaddr here, removing
622 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
623 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
624 Set STYP_INFO for .comment.
625 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
626 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

629 (do_linenos_for): Set lineno size in object_headers.
630 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
631 set s_vaddr here. If string_byte_count remains 4, set it back to
632 0, and only write strings out if there are some. Call
633 fill_section before do_relocs_for and do_linenos_for.
634 (obj_coff_section): Handle optional quoted second argument giving
635 section characteristics.
636 (obj_coff_bss): Added to handle .bss.
637 (obj_coff_ident): Added to handle .ident (puts string in .comment
639 (obj_coff_lcomm): Put common symbols in .bss, not .data.
640 (fixup_mdeps): Change to segment. Call frag_wane after
642 (fixup_segment): Explicitly check S_IS_COMMON before making 386
643 adjustment (already happened only for common symbols, but this is

663 * config/obj-coff.h: Don't use #elif.
665 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
666 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
668 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
670 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

695 never set segment address for SEG_E2 (.bss) and don't write out
696 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
697 (obj_coff_endef): Don't merge labels or symbols awaiting forward
698 definitions, and don't merge tags with non-tags. Check for .bf
699 rather than just checking whether the second character is b and
700 the third character is f.
701 (obj_coff_val): gcc can generate values which we don't handle
702 correctly; discard information for now, since it only affects the
703 debugging information.

705 (yank_symbols): Don't merge labels.
706 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
707 already defined. Fill subsegments with NOP_OPCODE, not 0. Don't

709 (obj_coff_section): Accept and ignore a trailing quoted string, as
710 used in AT&T i386 syntax.
711 (fixup_segment): Take segment as argument. On the i386, adjust PC
712 relative addends by the segment vaddr.

816 xrealloc from xrealloc.c.
817 * xrealloc.c: Deleted.
818 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.

901 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
902 with a single set using PARAMS macro.
904 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

917 * app.c (do_scrub_next_char): Need double-\ before `000' to show
918 printed rep of null character.

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

963 Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com)
965 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
966 * tc-z8k.c: lots of bug fixes
968 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
970 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
971 #elif, since it is not supported by old compilers.
972 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
973 couple of expressions in tc-m68k.c.
975 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
977 * read.c (cons): If NO_RELOC is defined, use it.
979 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
981 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
983 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
984 local labels to start with a .) and set REGISTER_PREFIX to %.
985 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
987 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

1001 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
1003 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
1004 sections starting from zero, rather than making them consecutive.
1005 This makes subsequent reloc calculations easier, esp if the object
1006 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
1007 allocate lcomm in .data rather than in .bss. It seems that some
1008 tools can't cope with a non-zero sized bss before linkage.
1010 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
1012 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
1013 throughout. That enum no longer means what we thought it meant.

1034 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
1036 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
1037 .word is < -32768 or > 32767. The -J flag causes the error to be
1038 ignored. This is to catch over-sized switches generated by gcc on
1039 systems which don't support the broken .word hack.
1040 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
1041 write.c (fixup_segment): check for signed .word overflow if
1042 WARN_SIGNED_OVERFLOW_WORD.

1071 From Steve Chamberlain:
1072 Makefile.in: Handle m68*-*-coff*.
1073 read.c, read.h: add mult argument to s_space
1075 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
1076 Motorola and MIT syntax; gas can now assemble either type of

1120 * config/tc-m68k.c (init_table): Now const. Always include 68851
1121 data, so that "bc" is available to 68040 cache instructions.
1122 Added "tt0", "tt1", and 68ec030 variants.
1123 (md_assemble): Complain if 68000 (only) and 68881 are specified.
1124 (enum _register): Added TT0, TT1.
1125 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
1126 line number correctly in "internal error" messages. Don't print

1152 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
1153 has already been formatted (but may still contain %-characters).
1156 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
1158 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
1159 written with indirection on the last two operands, which can be
1160 either data or address registers. Added a new operand type 'r'
1161 which accepts either register type. Added '(' to notend stuff in
1162 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

1508 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1509 local labels didn't work.
1510 * listing.c (list_symbol_table): don't core dump when there's no
1512 * write.c, write.h: call fix_new with the right number of args on
1514 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
1517 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1519 * app.c: MRI compatibility - allow single quote to start a string.
1520 * as.c: fix typo recently introduced.
1521 * as.h : Don't include aout/reloc.h - it's not right for COFF!
1522 * expr.c: Much rewriting, to accomodate MRI syntax for
1523 expressions. Also easier to read now.
1524 * listing.c: Put back defuns
1525 * read.c: modified to accept MRI syntax, put back listing pseudo
1526 ops so that an assembler built with NO_LISTING ignores list ops
1528 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1529 machine is a SPARC or a 29K.
1530 * config/obj-aout.c: added s_sect pseudo op
1531 * config/obj-coffbfd.c: lints, set the filehdr flags right and
1532 fill in the timestamp.
1533 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1534 anymore, define all the relocs which the tc-<x> bit will use so we
1535 can translate from them to the coff types.
1536 * config/tc-a29k.c: reloc_type isn't ane enum any more
1537 * config/tc-m68k.c: Added NO_RELOC definition.
1539 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1541 * Makefile.in: put header files before C source for TAGS; remove
1542 references to non-existent syscalls.h.
1544 * read.c, write.c subsegs.c: back out the .bss changes.
1546 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1548 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1552 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
1554 * symbols.c (local_label_name): symbols now start with ^A.
1556 * read.c, subsegs.c, write.c obj-coff.c: added handling of
1557 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1558 generate these sections. .align: will use NOP_OPCODE or 0
1559 for padding. This is just for being nice to the
1562 * expr.c (operand): changed to generate local label "\001L0"
1563 starting with a ^A so that it is recognized as a local label.
1565 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1567 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1568 i/o opcodes - inb, inw, outb and outw. string manipulation with
1569 att syntax - scmp, slod, smov, ssca, ssto.
1571 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1572 to just after .file .
1574 In obj_crawl_symbol_chain() where it tries to put the external
1575 symbols apart, with the condition:
1576 (!S_IS_DEFINED(symbolP) &&
1577 !S_IS_DEBUG(symbolP) &&
1578 !SF_GET_STATICS(symbolP))
1579 it was moving too many symbols out. So I switch it back to the
1581 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1583 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1584 so that we don't use the F_RELFLG which make the linker complain
1585 that somebody has stripped the relocation info.
1587 Also, the AIX ld program require that the relocation table
1588 is sorted by r_vaddr like the standard ATT assembler does.
1590 [he also changed the sizeof(struct ...)'s into the coff
1591 style FOOSZ macros. I'm not sure this is right, but I can't
1592 remember why. xoxorich.]
1594 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
1596 * Makefile.in, configure.in, doc: use the doc. Build it, install
1599 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
1601 * read.c: white space and comments only.
1603 * configure.in: use the new atof-ns32.c for ns32k.
1605 * write.c: comment change only.
1607 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
1608 aren't yet integrated.
1610 * tc-i860.[hc]: blew off the dust. Something must still be done
1611 about conflicting relocation types.
1613 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1616 * tc-i960.c, tc-sparc.c: white space and comments only.
1618 * tc-a29k.h: delete duplicate macro definition.
1620 * new file atof-ns32k.c copied from hack's last unreleased gas.
1622 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
1624 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1627 * nearly everything. flush ChangeLog, package as gas-1.92.1.
1628 ChangeLog's prior to this are sketchy at best. I have logs.
1629 They just aren't ChangeLogs.
