1423         accepting the 4100 as a MIPS architecture variant (md_begin,
1424         macro_build, mips_ip, md_parse_option). Adding suitable
1425         command-line OPTIONs, and updating the help text (md_show_usage).
1426

1428
1429         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
1430         BFD_ASSEMBLER is defined.
1431
1432         * Use one active frag and one obstack per frag chain:
1433         * frags.c (frags): Variable deleted.
1434         (frag_alloc): New function.
1435         (frag_grow, frag_more, frag_variant, frag_now_fix,

1438         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1439         entry and exit, and that old frag_now has non-zero type.  Replace
1440         "know" uses with "assert".  Use frag_alloc instead of mucking with
1441         obstack alignment.
1442         * frags.h (frags): Declaration deleted.
1443         * subsegs.h (struct frchain): Add new field frch_frag_now.

1446         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
1447         give it any stricter alignment than frchainS structures need.  Do
1448         not initialize frags obstack.  Set frag_now to point to
1449         dummy_obstack.  Initialize absolute_frchain.
1450         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1451         field of frchainS.  Don't create new frags on section switch, and
1452         use frag_alloc when creating a new frag chain.  For absolute
1453         section, set frchain_now to absolute_frchain.  Verify that
1454         frch_last and frag_now match on entry and exit.  Initialize
1455         per-chain obstack, and under gcc, set required alignment to that
1456         needed by fragS structure.
1457
1458         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1459
1460         * stabs.c (get_stab_string_offset): Only copy input string if a

1462         (s_stab_generic): Cache stab section name to bypass lookups, since
1463         usually it will match.  Could be made faster still by changing the
1464         memory allocation rules.
1465         (s_xstab): Cache section name to bypass repeated string
1466         allocation.

1468         * frags.c (frag_new): Deleted register declarations.
1469
1470         * listing.c (frag_now): Don't declare.

1483         testsuite directory.
1484         (clean-here): Don't delete testsuite.  Instead, delete only the
1485         files within it that would be generated by running tests.
1486
1487         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1488         frag_now_fix instead of accessing obstack info directly.
1489         * config/tc-arm.c (s_ltorg): Ditto.
1490         (md_assemble): Ditto.
1491
1492         * config/tc-i386.c (md_assemble): Call frag_grow instead of
