1437
1438         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
1439         BFD_ASSEMBLER is defined.

1441         * Use one active frag and one obstack per frag chain:
1442         * frags.c (frags): Variable deleted.
1443         (frag_alloc): New function.
1444         (frag_grow, frag_more, frag_variant, frag_now_fix,

1447         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1448         entry and exit, and that old frag_now has non-zero type.  Replace
1449         "know" uses with "assert".  Use frag_alloc instead of mucking with
1450         obstack alignment.
1451         * frags.h (frags): Declaration deleted.
1452         * subsegs.h (struct frchain): Add new field frch_frag_now.

1458         dummy_obstack.  Initialize absolute_frchain.
1459         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1460         field of frchainS.  Don't create new frags on section switch, and
1461         use frag_alloc when creating a new frag chain.  For absolute
1462         section, set frchain_now to absolute_frchain.  Verify that
1463         frch_last and frag_now match on entry and exit.  Initialize
1464         per-chain obstack, and under gcc, set required alignment to that
1465         needed by fragS structure.

1467         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1468
1469         * stabs.c (get_stab_string_offset): Only copy input string if a

1471         (s_stab_generic): Cache stab section name to bypass lookups, since
1472         usually it will match.  Could be made faster still by changing the
1473         memory allocation rules.
1474         (s_xstab): Cache section name to bypass repeated string
1475         allocation.

1492         testsuite directory.
1493         (clean-here): Don't delete testsuite.  Instead, delete only the
1494         files within it that would be generated by running tests.
1495
1496         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1497         frag_now_fix instead of accessing obstack info directly.

1499         (md_assemble): Ditto.
1500
1501         * config/tc-i386.c (md_assemble): Call frag_grow instead of
