1343         .align value.
1344         * doc/c-z8k.texi (Z8000 Directives, global): Fix minor typo.
1345         (Z8000 Directives, even): Don't give numeric align value, instead

1363         same name.
1364
1365 Tue Oct 24 14:50:38 1995  Michael Meissner  <meissner@tiktok.cygnus.com>

1367         * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
1368         TC_FORCE_RELOCATION, taking an additional section argument.  If
1369         the section of the target symbol is not the same as the current
1370         section, always force the relocation to be used.
1371         (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
1372
1373         * config/tc-ppc.c (md_pcrel_from_section): Rename from the
1374         md_pcrel_from function, taking an additional section argument.
1375         Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.
1376

1380         (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
1381         md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
1382         TC_FORCE_RELOCATION.
1383
1384 Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>
1385
1386         * input-scrub.c (as_where): Set name to null pointer if we don't
1387         have a file name.
1388         * messages.c (identify): Only print filename if non-null.
1389         (as_show_where): Ditto, for line number too.

1393         opened, consider it an error.
1394
1395 Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>
1396
1397         * config/tc-mips.c: Added mips_4100 control, and support for
1398         accepting the 4100 as a MIPS architecture variant (md_begin,
1399         macro_build, mips_ip, md_parse_option). Adding suitable
1400         command-line OPTIONs, and updating the help text (md_show_usage).
1401
1402 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
1403
1404         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
1405         BFD_ASSEMBLER is defined.
1406
1407         * Use one active frag and one obstack per frag chain:
1408         * frags.c (frags): Variable deleted.
1409         (frag_alloc): New function.
1410         (frag_grow, frag_more, frag_variant, frag_now_fix,
1411         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
1412         frags variable.
1413         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1414         entry and exit, and that old frag_now has non-zero type.  Replace
1415         "know" uses with "assert".  Use frag_alloc instead of mucking with
1416         obstack alignment.
1417         * frags.h (frags): Declaration deleted.
1418         * subsegs.h (struct frchain): Add new field frch_frag_now.

1420         variables.
1421         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
1422         give it any stricter alignment than frchainS structures need.  Do
1423         not initialize frags obstack.  Set frag_now to point to
1424         dummy_obstack.  Initialize absolute_frchain.
1425         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1426         field of frchainS.  Don't create new frags on section switch, and
1427         use frag_alloc when creating a new frag chain.  For absolute
1428         section, set frchain_now to absolute_frchain.  Verify that
1429         frch_last and frag_now match on entry and exit.  Initialize
1430         per-chain obstack, and under gcc, set required alignment to that
1431         needed by fragS structure.
1432
1433         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1434
1435         * stabs.c (get_stab_string_offset): Only copy input string if a
1436         fresh copy is needed, not if the section already exists.
1437         (s_stab_generic): Cache stab section name to bypass lookups, since
1438         usually it will match.  Could be made faster still by changing the
1439         memory allocation rules.
1440         (s_xstab): Cache section name to bypass repeated string
1441         allocation.
1442
1443         * frags.c (frag_new): Deleted register declarations.
1444
1445         * listing.c (frag_now): Don't declare.

1447         * as.c (chunksize): New variable.
1448         (debug_memory): New variable.
1449         (main): If debug_memory is set, reduce chunksize and
1450         _bfd_chunksize.
1451         * as.h (chunksize): Declare it.
1452         * read.c (read_begin): Use it.
1453
1454         * config/tc-alpha.c (md_shortopts): Include 'g'.
1455         (md_parse_option): Ignore it.
1456
1457         * Makefile.in (distclean): Remove Makefile and config.status from
1458         testsuite directory.
1459         (clean-here): Don't delete testsuite.  Instead, delete only the
1460         files within it that would be generated by running tests.
1461
1462         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1463         frag_now_fix instead of accessing obstack info directly.
1464         * config/tc-arm.c (s_ltorg): Ditto.
1465         (md_assemble): Ditto.
1466
1467         * config/tc-i386.c (md_assemble): Call frag_grow instead of
1468         obstack_room.

1470 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
1471
1472         * stabs.c (aout_process_stab): Insert debug symbol into symbol
1473         chain after parsing value expression, if any, to avoid separating
1474         continued .stabs lines.
