 998         not initialize frags obstack.  Set frag_now to point to
 999         dummy_obstack.  Initialize absolute_frchain.
1000         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1001         field of frchainS.  Don't create new frags on section switch, and
1002         use frag_alloc when creating a new frag chain.  For absolute
1003         section, set frchain_now to absolute_frchain.  Verify that
1004         frch_last and frag_now match on entry and exit.  Initialize
1005         per-chain obstack, and under gcc, set required alignment to that
1006         needed by fragS structure.
1007
1008         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.

1012         (s_stab_generic): Cache stab section name to bypass lookups, since
1013         usually it will match.  Could be made faster still by changing the
1014         memory allocation rules.
1015         (s_xstab): Cache section name to bypass repeated string
1016         allocation.
1017
1018         * frags.c (frag_new): Deleted register declarations.
1019

1036
1037         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1038         frag_now_fix instead of accessing obstack info directly.
1039         * config/tc-arm.c (s_ltorg): Ditto.
1040         (md_assemble): Ditto.
1041
1042         * config/tc-i386.c (md_assemble): Call frag_grow instead of

1047         * stabs.c (aout_process_stab): Insert debug symbol into symbol

1127
1128         * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
