 676         variables.
 677         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 678         give it any stricter alignment than frchainS structures need.  Do
 679         not initialize frags obstack.  Set frag_now to point to
 680         dummy_obstack.  Initialize absolute_frchain.
 681         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 682         field of frchainS.  Don't create new frags on section switch, and
 683         use frag_alloc when creating a new frag chain.  For absolute
 684         section, set frchain_now to absolute_frchain.  Verify that
 685         frch_last and frag_now match on entry and exit.  Initialize
 686         per-chain obstack, and under gcc, set required alignment to that
 687         needed by fragS structure.
 688
 689         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 690
 691         * stabs.c (get_stab_string_offset): Only copy input string if a
 692         fresh copy is needed, not if the section already exists.
 693         (s_stab_generic): Cache stab section name to bypass lookups, since
 694         usually it will match.  Could be made faster still by changing the
 695         memory allocation rules.
 696         (s_xstab): Cache section name to bypass repeated string
 697         allocation.
 698
 699         * frags.c (frag_new): Deleted register declarations.
 700
 701         * listing.c (frag_now): Don't declare.

 714         testsuite directory.
 715         (clean-here): Don't delete testsuite.  Instead, delete only the
 716         files within it that would be generated by running tests.
 717
 718         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 719         frag_now_fix instead of accessing obstack info directly.
 720         * config/tc-arm.c (s_ltorg): Ditto.
 721         (md_assemble): Ditto.
 722
 723         * config/tc-i386.c (md_assemble): Call frag_grow instead of

 727
 728         * stabs.c (aout_process_stab): Insert debug symbol into symbol
