6443         entry and exit, and that old frag_now has non-zero type.  Replace

6445         obstack alignment.
6446         * frags.h (frags): Declaration deleted.

6454         (subseg_set_rest): Save and restore frag_now in frch_frag_now
6455         field of frchainS.  Don't create new frags on section switch, and

6457         section, set frchain_now to absolute_frchain.  Verify that
6458         frch_last and frag_now match on entry and exit.  Initialize
6459         per-chain obstack, and under gcc, set required alignment to that

6466         (s_stab_generic): Cache stab section name to bypass lookups, since
6467         usually it will match.  Could be made faster still by changing the
6468         memory allocation rules.
6469         (s_xstab): Cache section name to bypass repeated string
6470         allocation.

6490
6491         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
6492         frag_now_fix instead of accessing obstack info directly.

6495
