28 Patches from Eric Youngdale:
29 * make-gas.com: Find obstack.obj if it's not in the current
31 * read.c (s_ignore): Don't declare is_end_of_line. It's
32 redundant, and triggers a VMS gcc compiler bug.
34 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
35 current segment as an argument. (Ignored in all cases but VMS.)

353 (operand): Treat zero byte as end-of-operand.
355 * configure.in (per-target): Look for with_bfd_assembler option.

365 * expr.c: Add "const" modifier to hex_value.
366 * symbols.c: Finish conversion to S_* macros in the VMS only
367 parts of the program. Add "const" modifier to
368 md_[long,short]_jump_size. Remove declaration of const_flag
369 (which will be declared in obj-vms.h).
370 * write.c: Add "const" modifier to md_[long,short]_jump_size.
371 Fix arguments to VMS_write_object_file.
372 * config-gas.com: New file. Script for VMS systems to set up the
373 configuration to build gas for VMS, and create config.status.
374 * make-gas.com: Redone to work with new scheme.
375 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
377 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
378 will swap bytes if needed on a big endian system. Use throughout
380 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
381 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
382 types of malformed stabs. Change parsing algorithm so that we are
383 more certain of having all of the information that we need on hand.

385 resolve the data types of as many struct elements as possible
386 when some part of the struct is not fully defined by the compiler.

389 * obj-vms.c (VMS_write_object_file): Define all vtable psects
390 as symbols as well in the object file. Look for external functions

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

428 (section_alignment): Declare only if not BFD_ASSEMBLER.
429 (big_section, reg_section, pass1_section, diff_section,
430 absent_section, text_section, data_section, bss_section): If
431 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
432 mapping to segT enum values.
433 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
434 if these are used or defined, if BFD_ASSEMBLER.
435 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
436 subseg_new split into two functions.
437 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
439 * as.h (volatile): Don't define if already defined.
440 (had_errors, had_warnings): Provide prototypes for ANSI C even if
442 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
443 declare with format attribute for -Wformat checking.
445 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
447 * app.c, config/tc-*.c: Don't include read.h, since it is already
450 * These are based on patches from Minh Tran-le
451 <mtranle@paris.intellicorp.com>.
452 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
453 obj_format coffbfd and gas_target i386coff for target.
454 (i[34]86-*-isc*): New host (uses sysv).
455 * config/i386aix.mt: Removed (no longer used).
456 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
458 (LDFLAGS): Added, defined as -shlib.
459 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
460 * config/te-sco386.h (LOCAL_LABEL): Don't define.
461 (DOT_LABEL_PREFIX): Define.
462 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
463 name rather than L0\001.
464 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
466 * symbols.c, symbols.h (local_bss_counter): Removed.
467 * write.c (write_object_file): bss no longer uses
468 local_bss_counter. Pass correct data and bss size to
469 VMS_write_object_file.
470 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
471 argument, rather than using local_bss_counter.
472 * config/tc-m88k.c (s_bss): Don't use local_bss_counter.
473 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
474 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
475 (size_section): Restored sanity check.
476 (do_relocs_for): Base section address on s_paddr rather than
477 computing it. Adjust a29k R_IHIHALF special case to account for
478 section paddr (used to require paddr to be zero). If there are no
479 reclos, set s_relptr to 0. Set relocation size in object_headers.
480 (fill_section): Always set s_vaddr here, removing
481 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
482 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
483 Set STYP_INFO for .comment.

708 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
710 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;

829 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
830 #elif, since it is not supported by old compilers.

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

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

922 * input-scrub.c (input_scrub_push): call input_file_begin, not
924 messages.c (as_perror): print ": " between the passed in error and
925 the strerror, like perror does.
927 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

947 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
950 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
952 * Makefile.in (LIBS): Include opcode library.
954 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
956 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

979 * config/tc-m68k.c (init_table): Now const. Always include 68851
980 data, so that "bc" is available to 68040 cache instructions.

982 (md_assemble): Complain if 68000 (only) and 68881 are specified.
983 (enum _register): Added TT0, TT1.
984 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
985 line number correctly in "internal error" messages. Don't print
986 architecture-mismatch message for operand errors.
988 From Colin Smith (colin@wrs.com):
989 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
990 than install_operand.
992 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)

1015 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
1017 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
1018 written with indirection on the last two operands, which can be
1019 either data or address registers. Added a new operand type 'r'
1020 which accepts either register type. Added '(' to notend stuff in
1021 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

1133 characteristics have been), default to 68020. Don't need extra
1134 quotes around error string.

1267 * write.c (write_object_file): For b.out format, round up section
1268 start addresses to match required alignment.
1270 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
1272 * Makefile.in (install): Install into $(tooldir)/bin, since that's
1273 where gcc looks for it.
1275 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
1277 * Makefile.in: Changed some lines to be less confusing for some

1347 * expr.c (operand): if can't work out what sort of operand it is,
1348 then look through FLT_CHARS for a hint.
1350 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
1352 * Makefile.in, configure.in: removed traces of namesubdir,

1356 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
1357 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1358 copyrights to '92, changed some from Cygnus to FSF.
1360 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1362 * expr.c: If an expression is single comma, then return with
1363 SEG_ABSENT rather than an error - since the sparc front end does
1364 really strange things with things like fbge,a
1366 * as.h: include bfd.h if using many sections
1367 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1368 local labels didn't work.
1369 * listing.c (list_symbol_table): don't core dump when there's no
1371 * write.c, write.h: call fix_new with the right number of args on

1376 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1378 * app.c: MRI compatibility - allow single quote to start a string.
1379 * as.c: fix typo recently introduced.
1380 * as.h : Don't include aout/reloc.h - it's not right for COFF!
1381 * expr.c: Much rewriting, to accomodate MRI syntax for
1382 expressions. Also easier to read now.
1383 * listing.c: Put back defuns
1384 * read.c: modified to accept MRI syntax, put back listing pseudo
1385 ops so that an assembler built with NO_LISTING ignores list ops
1387 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1388 machine is a SPARC or a 29K.
1389 * config/obj-aout.c: added s_sect pseudo op
1390 * config/obj-coffbfd.c: lints, set the filehdr flags right and
1391 fill in the timestamp.
1392 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1393 anymore, define all the relocs which the tc-<x> bit will use so we
1394 can translate from them to the coff types.
1395 * config/tc-a29k.c: reloc_type isn't ane enum any more
1396 * config/tc-m68k.c: Added NO_RELOC definition.
1398 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1400 * Makefile.in: put header files before C source for TAGS; remove
1401 references to non-existent syscalls.h.
1403 * read.c, write.c subsegs.c: back out the .bss changes.
1405 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1407 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1411 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
1413 * symbols.c (local_label_name): symbols now start with ^A.
1415 * read.c, subsegs.c, write.c obj-coff.c: added handling of
1416 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1417 generate these sections. .align: will use NOP_OPCODE or 0
1418 for padding. This is just for being nice to the
1421 * expr.c (operand): changed to generate local label "\001L0"
1422 starting with a ^A so that it is recognized as a local label.
1424 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1426 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1427 i/o opcodes - inb, inw, outb and outw. string manipulation with
1428 att syntax - scmp, slod, smov, ssca, ssto.
1430 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1431 to just after .file .
1433 In obj_crawl_symbol_chain() where it tries to put the external
1434 symbols apart, with the condition:
1435 (!S_IS_DEFINED(symbolP) &&
1436 !S_IS_DEBUG(symbolP) &&
1437 !SF_GET_STATICS(symbolP))
1438 it was moving too many symbols out. So I switch it back to the
1440 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1442 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1443 so that we don't use the F_RELFLG which make the linker complain
1444 that somebody has stripped the relocation info.
1446 Also, the AIX ld program require that the relocation table
1447 is sorted by r_vaddr like the standard ATT assembler does.
1449 [he also changed the sizeof(struct ...)'s into the coff
1450 style FOOSZ macros. I'm not sure this is right, but I can't
1451 remember why. xoxorich.]
1453 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

1462 * configure.in: use the new atof-ns32.c for ns32k.
1464 * write.c: comment change only.
1466 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
1467 aren't yet integrated.
1469 * tc-i860.[hc]: blew off the dust. Something must still be done
1470 about conflicting relocation types.
1472 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1475 * tc-i960.c, tc-sparc.c: white space and comments only.
1477 * tc-a29k.h: delete duplicate macro definition.
1479 * new file atof-ns32k.c copied from hack's last unreleased gas.
1481 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
1483 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1486 * nearly everything. flush ChangeLog, package as gas-1.92.1.
1487 ChangeLog's prior to this are sketchy at best. I have logs.
1488 They just aren't ChangeLogs.
