3 Patches from Eric Youngdale:
4 * make-gas.com: Find obstack.obj if it's not in the current
6 * read.c (s_ignore): Don't declare is_end_of_line. It's
7 redundant, and triggers a VMS gcc compiler bug.
9 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
10 current segment as an argument. (Ignored in all cases but VMS.)
11 All callers and definitions changed.

307 * config/tc-sparc.c (architecture_requested, warn_on_bump,
308 md_relax_table): Use default zero initialization.
309 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
310 latter, instead of selecting with preprocessor conditionals.
312 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
314 * configure.in: recognise all sparclite variants

324 * expr.c (operand): If character other than comma or newline is a
325 logical end-of-line character, use the newline case.
327 (operand): Set X_add_number field for floating-point numbers.
328 (operand): Treat zero byte as end-of-operand.
330 * configure.in (per-target): Look for with_bfd_assembler option.

333 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
334 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
335 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.

337 parts of the program. Add "const" modifier to hex_value.
338 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
340 * expr.c: Add "const" modifier to hex_value.
341 * symbols.c: Finish conversion to S_* macros in the VMS only
342 parts of the program. Add "const" modifier to
343 md_[long,short]_jump_size. Remove declaration of const_flag
344 (which will be declared in obj-vms.h).
345 * write.c: Add "const" modifier to md_[long,short]_jump_size.
346 Fix arguments to VMS_write_object_file.
347 * config-gas.com: New file. Script for VMS systems to set up the
348 configuration to build gas for VMS, and create config.status.
349 * make-gas.com: Redone to work with new scheme.
350 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
352 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
353 will swap bytes if needed on a big endian system. Use throughout
355 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
356 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
357 types of malformed stabs. Change parsing algorithm so that we are
358 more certain of having all of the information that we need on hand.
359 * obj-vms.c (final_forward_reference): New function, used to help
360 resolve the data types of as many struct elements as possible
361 when some part of the struct is not fully defined by the compiler.
362 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
364 * obj-vms.c (VMS_write_object_file): Define all vtable psects
365 as symbols as well in the object file. Look for external functions
366 that start with "__vt.", and turn them into variables, since the

378 SEG_DATA or SEG_E1 if needed.
379 (s_lcomm): Likewise with bss_section.
380 (s_fill): Use memset, not bzero.
382 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

403 (section_alignment): Declare only if not BFD_ASSEMBLER.
404 (big_section, reg_section, pass1_section, diff_section,
405 absent_section, text_section, data_section, bss_section): If
406 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
407 mapping to segT enum values.
408 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
409 if these are used or defined, if BFD_ASSEMBLER.
410 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
411 subseg_new split into two functions.
412 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
414 * as.h (volatile): Don't define if already defined.
415 (had_errors, had_warnings): Provide prototypes for ANSI C even if
417 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
418 declare with format attribute for -Wformat checking.
420 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
422 * app.c, config/tc-*.c: Don't include read.h, since it is already
425 * These are based on patches from Minh Tran-le
426 <mtranle@paris.intellicorp.com>.
427 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
428 obj_format coffbfd and gas_target i386coff for target.
429 (i[34]86-*-isc*): New host (uses sysv).
430 * config/i386aix.mt: Removed (no longer used).
431 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
433 (LDFLAGS): Added, defined as -shlib.
434 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
435 * config/te-sco386.h (LOCAL_LABEL): Don't define.
436 (DOT_LABEL_PREFIX): Define.
437 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
438 name rather than L0\001.
439 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
441 * symbols.c, symbols.h (local_bss_counter): Removed.
442 * write.c (write_object_file): bss no longer uses
443 local_bss_counter. Pass correct data and bss size to
444 VMS_write_object_file.
445 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
446 argument, rather than using local_bss_counter.

448 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
449 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
450 (size_section): Restored sanity check.
451 (do_relocs_for): Base section address on s_paddr rather than
452 computing it. Adjust a29k R_IHIHALF special case to account for
453 section paddr (used to require paddr to be zero). If there are no
454 reclos, set s_relptr to 0. Set relocation size in object_headers.
455 (fill_section): Always set s_vaddr here, removing
456 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
457 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
458 Set STYP_INFO for .comment.
459 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
460 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

462 H_{SET,GET}_* macros.
463 (do_linenos_for): Set lineno size in object_headers.
464 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
465 set s_vaddr here. If string_byte_count remains 4, set it back to
466 0, and only write strings out if there are some. Call
467 fill_section before do_relocs_for and do_linenos_for.
468 (obj_coff_section): Handle optional quoted second argument giving
469 section characteristics.
470 (obj_coff_bss): Added to handle .bss.
471 (obj_coff_ident): Added to handle .ident (puts string in .comment
473 (obj_coff_lcomm): Put common symbols in .bss, not .data.
474 (fixup_mdeps): Change to segment. Call frag_wane after
476 (fixup_segment): Explicitly check S_IS_COMMON before making 386
477 adjustment (already happened only for common symbols, but this is

533 rather than just checking whether the second character is b and
534 the third character is f.

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

678 * all files: Whitespace changes for GNU indentation style, done by
679 GNU `indent'. Some cleanup still needed, especially of comments.
681 * configure.in: No te-386bsd.h file exists; don't try to use it.
683 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
685 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
686 could be doing emulation.

717 comment_chars, line_comment_chars and line_seperator_chars
718 consistently const, and always initialized them. Included read.h.
720 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)

752 printed rep of null character.
754 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
756 * obj-coffbfd.c (write_object_file): check return value of
759 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
761 * Support for i386-sysv.
762 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

800 * tc-z8k.c: lots of bug fixes
802 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
804 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
805 #elif, since it is not supported by old compilers.
806 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
807 couple of expressions in tc-m68k.c.
809 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
811 * read.c (cons): If NO_RELOC is defined, use it.
813 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
815 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
817 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
818 local labels to start with a .) and set REGISTER_PREFIX to %.
819 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
821 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

832 * listing.c (debugging_pseudo): Add stabs and stabn as things to
835 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
837 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
838 sections starting from zero, rather than making them consecutive.
839 This makes subsequent reloc calculations easier, esp if the object
840 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
841 allocate lcomm in .data rather than in .bss. It seems that some
842 tools can't cope with a non-zero sized bss before linkage.
844 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
846 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

865 * Makefile.in (install): if $(tooldir) exists, install as in
868 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
870 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
871 .word is < -32768 or > 32767. The -J flag causes the error to be
872 ignored. This is to catch over-sized switches generated by gcc on
873 systems which don't support the broken .word hack.
874 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
875 write.c (fixup_segment): check for signed .word overflow if
876 WARN_SIGNED_OVERFLOW_WORD.
878 * write.c (fixup_segment): fixed missing parens in expression
879 checking for byte or word overflow.

895 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
897 * input-scrub.c (input_scrub_push): call input_file_begin, not
899 messages.c (as_perror): print ": " between the passed in error and
900 the strerror, like perror does.
902 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
904 * Makefile.in: use gas_target instead of modifying target_cpu.
905 From Steve Chamberlain:
906 Makefile.in: Handle m68*-*-coff*.
907 read.c, read.h: add mult argument to s_space
909 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
910 Motorola and MIT syntax; gas can now assemble either type of

918 (write_object_file) call fixup_mdeps
919 (fixup_segment) set fx_subsy to 0.
920 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
922 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
925 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
927 * Makefile.in (LIBS): Include opcode library.
929 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
931 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
932 including zero are accepted, pass +0.0.

949 tc-i960.c (md_ri_to_chars): Always output bout object file in
950 little endian byte order (used to use endianness of host).
952 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
954 * config/tc-m68k.c (init_table): Now const. Always include 68851
955 data, so that "bc" is available to 68040 cache instructions.
956 Added "tt0", "tt1", and 68ec030 variants.
957 (md_assemble): Complain if 68000 (only) and 68881 are specified.
958 (enum _register): Added TT0, TT1.
959 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
960 line number correctly in "internal error" messages. Don't print
961 architecture-mismatch message for operand errors.
963 From Colin Smith (colin@wrs.com):
964 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
965 than install_operand.
967 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
969 * listing.c (buffer_line): rewind to the start of include
970 files, they might be included twice.
972 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
974 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)

977 one element of a family.
979 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
981 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB

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

1245 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
1247 * Makefile.in (install): Install into $(tooldir)/bin, since that's
1248 where gcc looks for it.
1250 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
1252 * Makefile.in: Changed some lines to be less confusing for some

1325 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
1327 * Makefile.in, configure.in: removed traces of namesubdir,

1331 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
1332 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1333 copyrights to '92, changed some from Cygnus to FSF.
1335 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1337 * expr.c: If an expression is single comma, then return with
1338 SEG_ABSENT rather than an error - since the sparc front end does
1339 really strange things with things like fbge,a
1341 * as.h: include bfd.h if using many sections
1342 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1343 local labels didn't work.
1344 * listing.c (list_symbol_table): don't core dump when there's no
1346 * write.c, write.h: call fix_new with the right number of args on

1351 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1353 * app.c: MRI compatibility - allow single quote to start a string.
1354 * as.c: fix typo recently introduced.
1355 * as.h : Don't include aout/reloc.h - it's not right for COFF!
1356 * expr.c: Much rewriting, to accomodate MRI syntax for
1357 expressions. Also easier to read now.
1358 * listing.c: Put back defuns
1359 * read.c: modified to accept MRI syntax, put back listing pseudo
1360 ops so that an assembler built with NO_LISTING ignores list ops
1362 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1363 machine is a SPARC or a 29K.
1364 * config/obj-aout.c: added s_sect pseudo op
1365 * config/obj-coffbfd.c: lints, set the filehdr flags right and
1366 fill in the timestamp.
1367 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1368 anymore, define all the relocs which the tc-<x> bit will use so we
1369 can translate from them to the coff types.
1370 * config/tc-a29k.c: reloc_type isn't ane enum any more
1371 * config/tc-m68k.c: Added NO_RELOC definition.
1373 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1375 * Makefile.in: put header files before C source for TAGS; remove
1376 references to non-existent syscalls.h.
1378 * read.c, write.c subsegs.c: back out the .bss changes.
1380 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1382 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1386 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
1388 * symbols.c (local_label_name): symbols now start with ^A.
1390 * read.c, subsegs.c, write.c obj-coff.c: added handling of
1391 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1392 generate these sections. .align: will use NOP_OPCODE or 0
1393 for padding. This is just for being nice to the
1396 * expr.c (operand): changed to generate local label "\001L0"
1397 starting with a ^A so that it is recognized as a local label.
1399 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1401 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1402 i/o opcodes - inb, inw, outb and outw. string manipulation with
1403 att syntax - scmp, slod, smov, ssca, ssto.
1405 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1406 to just after .file .
1408 In obj_crawl_symbol_chain() where it tries to put the external
1409 symbols apart, with the condition:
1410 (!S_IS_DEFINED(symbolP) &&
1411 !S_IS_DEBUG(symbolP) &&
1412 !SF_GET_STATICS(symbolP))
1413 it was moving too many symbols out. So I switch it back to the
1415 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1417 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1418 so that we don't use the F_RELFLG which make the linker complain
1419 that somebody has stripped the relocation info.
1421 Also, the AIX ld program require that the relocation table
1422 is sorted by r_vaddr like the standard ATT assembler does.
1424 [he also changed the sizeof(struct ...)'s into the coff
1425 style FOOSZ macros. I'm not sure this is right, but I can't
1426 remember why. xoxorich.]
1428 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

1437 * configure.in: use the new atof-ns32.c for ns32k.
1439 * write.c: comment change only.
1441 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
1442 aren't yet integrated.
1444 * tc-i860.[hc]: blew off the dust. Something must still be done
1445 about conflicting relocation types.
1447 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1450 * tc-i960.c, tc-sparc.c: white space and comments only.
1452 * tc-a29k.h: delete duplicate macro definition.
1454 * new file atof-ns32k.c copied from hack's last unreleased gas.
1456 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
1458 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1461 * nearly everything. flush ChangeLog, package as gas-1.92.1.
1462 ChangeLog's prior to this are sketchy at best. I have logs.
1463 They just aren't ChangeLogs.
