1473         * frags.c (frags): Variable deleted.

1478         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1479         entry and exit, and that old frag_now has non-zero type.  Replace
1480         "know" uses with "assert".  Use frag_alloc instead of mucking with
1481         obstack alignment.
1482         * frags.h (frags): Declaration deleted.
1483         * subsegs.h (struct frchain): Add new field frch_frag_now.

1486         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
1487         give it any stricter alignment than frchainS structures need.  Do
1488         not initialize frags obstack.  Set frag_now to point to
1489         dummy_obstack.  Initialize absolute_frchain.
1490         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1491         field of frchainS.  Don't create new frags on section switch, and
1492         use frag_alloc when creating a new frag chain.  For absolute
1493         section, set frchain_now to absolute_frchain.  Verify that
1494         frch_last and frag_now match on entry and exit.  Initialize
1495         per-chain obstack, and under gcc, set required alignment to that
1496         needed by fragS structure.
1497
1498         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1499
1500         * stabs.c (get_stab_string_offset): Only copy input string if a

1502         (s_stab_generic): Cache stab section name to bypass lookups, since
1503         usually it will match.  Could be made faster still by changing the
1504         memory allocation rules.
1505         (s_xstab): Cache section name to bypass repeated string
1506         allocation.

1523         testsuite directory.
1524         (clean-here): Don't delete testsuite.  Instead, delete only the
1525         files within it that would be generated by running tests.
1526
1527         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1528         frag_now_fix instead of accessing obstack info directly.

1530         (md_assemble): Ditto.
1531
1532         * config/tc-i386.c (md_assemble): Call frag_grow instead of
