 766         command-line OPTIONs, and updating the help text (md_show_usage).

 771         BFD_ASSEMBLER is defined.
 772
 773         * Use one active frag and one obstack per frag chain:
 774         * frags.c (frags): Variable deleted.
 775         (frag_alloc): New function.
 776         (frag_grow, frag_more, frag_variant, frag_now_fix,

 778         frags variable.
 779         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 780         entry and exit, and that old frag_now has non-zero type.  Replace
 781         "know" uses with "assert".  Use frag_alloc instead of mucking with
 782         obstack alignment.
 783         * frags.h (frags): Declaration deleted.

 787         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 788         give it any stricter alignment than frchainS structures need.  Do
 789         not initialize frags obstack.  Set frag_now to point to
 790         dummy_obstack.  Initialize absolute_frchain.
 791         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 792         field of frchainS.  Don't create new frags on section switch, and
 793         use frag_alloc when creating a new frag chain.  For absolute
 794         section, set frchain_now to absolute_frchain.  Verify that
 795         frch_last and frag_now match on entry and exit.  Initialize
 796         per-chain obstack, and under gcc, set required alignment to that
 797         needed by fragS structure.
 798
 799         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 800
 801         * stabs.c (get_stab_string_offset): Only copy input string if a
 802         fresh copy is needed, not if the section already exists.
 803         (s_stab_generic): Cache stab section name to bypass lookups, since
 804         usually it will match.  Could be made faster still by changing the
 805         memory allocation rules.
 806         (s_xstab): Cache section name to bypass repeated string
 807         allocation.

 817         * as.h (chunksize): Declare it.
 818         * read.c (read_begin): Use it.

 824         testsuite directory.

 827
 828         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 829         frag_now_fix instead of accessing obstack info directly.
 830         * config/tc-arm.c (s_ltorg): Ditto.
 831         (md_assemble): Ditto.
 832
 833         * config/tc-i386.c (md_assemble): Call frag_grow instead of
 834         obstack_room.

 837
 838         * stabs.c (aout_process_stab): Insert debug symbol into symbol
 839         chain after parsing value expression, if any, to avoid separating
 840         continued .stabs lines.
