11 Patches from Eric Youngdale:
12 * make-gas.com: Find obstack.obj if it's not in the current
13 directory.
14 * read.c (s_ignore): Don't declare is_end_of_line. It's
15 redundant, and triggers a VMS gcc compiler bug.
16
17 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
18 current segment as an argument. (Ignored in all cases but VMS.)
19 All callers and definitions changed.

24 case compile again.
25
26 Tue Mar 2 08:53:34 1993 Ken Raeburn (raeburn@cygnus.com)
27
28 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
29 so "~0x80" won't be rejected.
30
31 * config/obj-elf.c: No longer include elf/reloc.h.
32 (obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
33 (obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
34 routines.
35 (obj_elf_xstab): New routine.
36 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
37 argument to s_ignore. Put "#if 0" around unused code.
38 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
39 Call elf_xstabs for .stabs and .xstabs operators.
40
41 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
42
43 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
44 present.
45
46 * configure.in: mips-bsd configuration was missing format spec.
47 Should use aout.
48
49 * Makefile.in (Makefile): Depends on configure.in.
50
51 * config/tc-mips.c (append_insn): Don't check for alignment of
52 frag in memory; alignment of instructions in section is a separate
53 matter.
54
55 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
56 C availability.
57
58 * listing.h: Always provide function declarations, not macros, so

145 (subseg_set) [BFD_ASSEMBLER]: New function; change to a possibly
146 new section/subsection.
147
148 * read.c: Don't include ctype.h.
149 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
150 for now; should be machine-dependent.

314
315 * config/tc-sparc.c (architecture_requested, warn_on_bump,

337
338 * configure.in (per-target): Look for with_bfd_assembler option.
339 For now, only accept "no", until the merge is done.
340
341 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
342 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
343 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
344 * read.c: Finish conversion to S_* macros in the VMS only
345 parts of the program. Add "const" modifier to hex_value.
346 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
347 "ifdef OBJ_VMS".
348 * expr.c: Add "const" modifier to hex_value.
349 * symbols.c: Finish conversion to S_* macros in the VMS only
350 parts of the program. Add "const" modifier to
351 md_[long,short]_jump_size. Remove declaration of const_flag
352 (which will be declared in obj-vms.h).
353 * write.c: Add "const" modifier to md_[long,short]_jump_size.
354 Fix arguments to VMS_write_object_file.
355 * config-gas.com: New file. Script for VMS systems to set up the
356 configuration to build gas for VMS, and create config.status.
357 * make-gas.com: Redone to work with new scheme.
358 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
359 stabs directives.
360 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
361 will swap bytes if needed on a big endian system. Use throughout
362 as needed.
363 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
364 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
365 types of malformed stabs. Change parsing algorithm so that we are
366 more certain of having all of the information that we need on hand.
367 * obj-vms.c (final_forward_reference): New function, used to help
368 resolve the data types of as many struct elements as possible
369 when some part of the struct is not fully defined by the compiler.
370 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
371 stabs directives.
372 * obj-vms.c (VMS_write_object_file): Define all vtable psects
373 as symbols as well in the object file. Look for external functions
374 that start with "__vt.", and turn them into variables, since the
375 g++ compiler is incapable of doing this.
376 * tc-vax.c: Add '1' option for backward compatibility with older GCC
377 versions.
378 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
379 * input-scrub.c (as_where): Fix bug where as would crash if we did not
380 have the name of the source file yet.

382
383 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
384
385 * read.c (s_data): Always use "data_section", since it'll map to
386 SEG_DATA or SEG_E1 if needed.
387 (s_lcomm): Likewise with bss_section.
388 (s_fill): Use memset, not bzero.
389

409 otherwise, use seg_name array.
410 (seg_name): Declare only if not BFD_ASSEMBLER.
411 (section_alignment): Declare only if not BFD_ASSEMBLER.
412 (big_section, reg_section, pass1_section, diff_section,
413 absent_section, text_section, data_section, bss_section): If
414 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
415 mapping to segT enum values.
416 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
417 if these are used or defined, if BFD_ASSEMBLER.
418 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
419 subseg_new split into two functions.
420 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
421
422 * as.h (volatile): Don't define if already defined.

429
430 * app.c, config/tc-*.c: Don't include read.h, since it is already
431 included by as.h.
432
433 * These are based on patches from Minh Tran-le
434 <mtranle@paris.intellicorp.com>.
435 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
436 obj_format coffbfd and gas_target i386coff for target.
437 (i[34]86-*-isc*): New host (uses sysv).
438 * config/i386aix.mt: Removed (no longer used).
439 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
440 (MINUS_G): Removed.
441 (LDFLAGS): Added, defined as -shlib.
442 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
443 * config/te-sco386.h (LOCAL_LABEL): Don't define.
444 (DOT_LABEL_PREFIX): Define.
445 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
446 name rather than L0\001.
447 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
448 local_bss_counter.
449 * symbols.c, symbols.h (local_bss_counter): Removed.
450 * write.c (write_object_file): bss no longer uses
451 local_bss_counter. Pass correct data and bss size to

458 (size_section): Restored sanity check.
459 (do_relocs_for): Base section address on s_paddr rather than
460 computing it. Adjust a29k R_IHIHALF special case to account for
461 section paddr (used to require paddr to be zero). If there are no
462 reclos, set s_relptr to 0. Set relocation size in object_headers.
463 (fill_section): Always set s_vaddr here, removing
464 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
465 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
466 Set STYP_INFO for .comment.
467 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
468 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

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

499 (do_scrub_next_char): For \", return " not '.
500 (symbol_chars): Now const.
501
502 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
503 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
504
505 * config/obj-coff.h: Don't use #elif.
506
507 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
508 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
509
510 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
511

533 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
534 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
535 using ZERO_BASED_SEGMENTS.
536 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
537 never set segment address for SEG_E2 (.bss) and don't write out
538 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
539 (obj_coff_endef): Don't merge labels or symbols awaiting forward
540 definitions, and don't merge tags with non-tags. Check for .bf
541 rather than just checking whether the second character is b and
542 the third character is f.
543 (obj_coff_val): gcc can generate values which we don't handle
544 correctly; discard information for now, since it only affects the
545 debugging information.

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

551 (obj_coff_section): Accept and ignore a trailing quoted string, as
552 used in AT&T i386 syntax.
553 (fixup_segment): Take segment as argument. On the i386, adjust PC

685
686 * all files: Whitespace changes for GNU indentation style, done by
687 GNU `indent'. Some cleanup still needed, especially of comments.
688

692
693 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;

714 still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
715 the register name.
716 (insert_reg): put REGISTER_PREFIX before register names before

811
812 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
813 #elif, since it is not supported by old compilers.
814 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
815 couple of expressions in tc-m68k.c.
816
817 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
818
819 * read.c (cons): If NO_RELOC is defined, use it.
820
821 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.

824
825 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
826 local labels to start with a .) and set REGISTER_PREFIX to %.
827 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
828
829 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

844
845 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
846 sections starting from zero, rather than making them consecutive.
847 This makes subsequent reloc calculations easier, esp if the object
848 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
849 allocate lcomm in .data rather than in .bss. It seems that some
850 tools can't cope with a non-zero sized bss before linkage.

878 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
879 .word is < -32768 or > 32767. The -J flag causes the error to be
880 ignored. This is to catch over-sized switches generated by gcc on
881 systems which don't support the broken .word hack.

1308
1309 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
1310
1311 * Makefile.in: added check target.
1312
1313 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1314
1315 * Makefile.in: added tooldir and program_prefix.
1316
1317 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
1318
1319 * write.{c,h} (fix_new): Make these declarations consistent.
1320
1321 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
1322
1323 * Makefile.in (strerror.o): Add rule so that broken Sun make can
1324 work in subdirs.
1325
1326 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
1327
1328 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
1329
1330 * expr.c (operand): if can't work out what sort of operand it is,
1331 then look through FLT_CHARS for a hint.
1332
1333 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
1334
1335 * Makefile.in, configure.in: removed traces of namesubdir,
1336 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1337 copyrights to '92, changed some from Cygnus to FSF.
1338
1339 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
1340 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1341 copyrights to '92, changed some from Cygnus to FSF.
1342
1343 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1344
1345 * expr.c: If an expression is single comma, then return with
1346 SEG_ABSENT rather than an error - since the sparc front end does
1347 really strange things with things like fbge,a
1348
1349 * as.h: include bfd.h if using many sections
1350 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
1351 local labels didn't work.
1352 * listing.c (list_symbol_table): don't core dump when there's no
1353 symbol there.
1354 * write.c, write.h: call fix_new with the right number of args on
1355 the H8.
1356 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
1357 errors nices
1358
1359 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1360
1361 * app.c: MRI compatibility - allow single quote to start a string.
1362 * as.c: fix typo recently introduced.
1363 * as.h : Don't include aout/reloc.h - it's not right for COFF!
1364 * expr.c: Much rewriting, to accomodate MRI syntax for
1365 expressions. Also easier to read now.
1366 * listing.c: Put back defuns
1367 * read.c: modified to accept MRI syntax, put back listing pseudo
1368 ops so that an assembler built with NO_LISTING ignores list ops
1369 rather than pukes.
1370 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
1371 machine is a SPARC or a 29K.
1372 * config/obj-aout.c: added s_sect pseudo op
1373 * config/obj-coffbfd.c: lints, set the filehdr flags right and
1374 fill in the timestamp.
1375 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
1376 anymore, define all the relocs which the tc-<x> bit will use so we
1377 can translate from them to the coff types.
1378 * config/tc-a29k.c: reloc_type isn't ane enum any more
1379 * config/tc-m68k.c: Added NO_RELOC definition.
1380
1381 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1382
1383 * Makefile.in: put header files before C source for TAGS; remove
1384 references to non-existent syscalls.h.
1385
1386 * read.c, write.c subsegs.c: back out the .bss changes.
1387
1388 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
1389
1390 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
1391
1392 * a.out.h: removed.
1393
1394 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
1395
1396 * symbols.c (local_label_name): symbols now start with ^A.
1397
1398 * read.c, subsegs.c, write.c obj-coff.c: added handling of
1399 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
1400 generate these sections. .align: will use NOP_OPCODE or 0
1401 for padding. This is just for being nice to the
1402 disassembler.
1403
1404 * expr.c (operand): changed to generate local label "\001L0"
1405 starting with a ^A so that it is recognized as a local label.
1406
1407 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
1408
1409 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
1410 i/o opcodes - inb, inw, outb and outw. string manipulation with
1411 att syntax - scmp, slod, smov, ssca, ssto.
1412
1413 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
1414 to just after .file .
1415
1416 In obj_crawl_symbol_chain() where it tries to put the external
1417 symbols apart, with the condition:
1418 (!S_IS_DEFINED(symbolP) &&
1419 !S_IS_DEBUG(symbolP) &&
1420 !SF_GET_STATICS(symbolP))
1421 it was moving too many symbols out. So I switch it back to the
1422 condition:
1423 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
1424
1425 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
1426 so that we don't use the F_RELFLG which make the linker complain
1427 that somebody has stripped the relocation info.
1428
1429 Also, the AIX ld program require that the relocation table
1430 is sorted by r_vaddr like the standard ATT assembler does.
1431
1432 [he also changed the sizeof(struct ...)'s into the coff
1433 style FOOSZ macros. I'm not sure this is right, but I can't
1434 remember why. xoxorich.]
1435
1436 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
1437
1438 * Makefile.in, configure.in, doc: use the doc. Build it, install
1439 it, clean it, etc.
1440
1441 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
1442
1443 * read.c: white space and comments only.
1444
1445 * configure.in: use the new atof-ns32.c for ns32k.
1446
1447 * write.c: comment change only.
1448
1449 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
1450 aren't yet integrated.
1451
1452 * tc-i860.[hc]: blew off the dust. Something must still be done
1453 about conflicting relocation types.
1454
1455 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
1456 real thing.
1457
1458 * tc-i960.c, tc-sparc.c: white space and comments only.
1459
1460 * tc-a29k.h: delete duplicate macro definition.
1461
1462 * new file atof-ns32k.c copied from hack's last unreleased gas.
1463
1464 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
1465
1466 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
1467 rather than abort.
1468
1469 * nearly everything. flush ChangeLog, package as gas-1.92.1.
1470 ChangeLog's prior to this are sketchy at best. I have logs.
1471 They just aren't ChangeLogs.
