1001         (frag_alloc): New function.
1002         (frag_grow, frag_more, frag_variant, frag_now_fix,
1003         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
1004         frags variable.
1005         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1006         entry and exit, and that old frag_now has non-zero type.  Replace
1007         "know" uses with "assert".  Use frag_alloc instead of mucking with
1008         obstack alignment.
1009         * frags.h (frags): Declaration deleted.
1010         * subsegs.h (struct frchain): Add new field frch_frag_now.
1011         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
1012         variables.
1013         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
1014         give it any stricter alignment than frchainS structures need.  Do
1015         not initialize frags obstack.  Set frag_now to point to
1016         dummy_obstack.  Initialize absolute_frchain.
1017         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1018         field of frchainS.  Don't create new frags on section switch, and
1019         use frag_alloc when creating a new frag chain.  For absolute
1020         section, set frchain_now to absolute_frchain.  Verify that
1021         frch_last and frag_now match on entry and exit.  Initialize
1022         per-chain obstack, and under gcc, set required alignment to that
1023         needed by fragS structure.
1024
1025         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1026
1027         * stabs.c (get_stab_string_offset): Only copy input string if a
1028         fresh copy is needed, not if the section already exists.
1029         (s_stab_generic): Cache stab section name to bypass lookups, since
1030         usually it will match.  Could be made faster still by changing the
1031         memory allocation rules.
1032         (s_xstab): Cache section name to bypass repeated string
1033         allocation.
1034
1035         * frags.c (frag_new): Deleted register declarations.
1036
1037         * listing.c (frag_now): Don't declare.
1038
1039         * as.c (chunksize): New variable.
1040         (debug_memory): New variable.
1041         (main): If debug_memory is set, reduce chunksize and
1042         _bfd_chunksize.
1043         * as.h (chunksize): Declare it.
1044         * read.c (read_begin): Use it.
1045
1046         * config/tc-alpha.c (md_shortopts): Include 'g'.
1047         (md_parse_option): Ignore it.
1048
1049         * Makefile.in (distclean): Remove Makefile and config.status from
1050         testsuite directory.
1051         (clean-here): Don't delete testsuite.  Instead, delete only the
1052         files within it that would be generated by running tests.
1053
1054         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1055         frag_now_fix instead of accessing obstack info directly.
1056         * config/tc-arm.c (s_ltorg): Ditto.
1057         (md_assemble): Ditto.
1058
1059         * config/tc-i386.c (md_assemble): Call frag_grow instead of
1060         obstack_room.

1062 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
1063
1064         * stabs.c (aout_process_stab): Insert debug symbol into symbol
1065         chain after parsing value expression, if any, to avoid separating
1066         continued .stabs lines.

1144
1145         * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
