1001
1002         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
1003         BFD_ASSEMBLER is defined.
1004
1005         * Use one active frag and one obstack per frag chain:
1006         * frags.c (frags): Variable deleted.
1007         (frag_alloc): New function.
1008         (frag_grow, frag_more, frag_variant, frag_now_fix,
1009         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
1010         frags variable.
1011         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1012         entry and exit, and that old frag_now has non-zero type.  Replace
1013         "know" uses with "assert".  Use frag_alloc instead of mucking with
1014         obstack alignment.
1015         * frags.h (frags): Declaration deleted.
1016         * subsegs.h (struct frchain): Add new field frch_frag_now.
1017         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
1018         variables.
1019         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
1020         give it any stricter alignment than frchainS structures need.  Do
1021         not initialize frags obstack.  Set frag_now to point to
1022         dummy_obstack.  Initialize absolute_frchain.
1023         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1024         field of frchainS.  Don't create new frags on section switch, and
1025         use frag_alloc when creating a new frag chain.  For absolute
1026         section, set frchain_now to absolute_frchain.  Verify that
1027         frch_last and frag_now match on entry and exit.  Initialize
1028         per-chain obstack, and under gcc, set required alignment to that
1029         needed by fragS structure.
1030
1031         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1032
1033         * stabs.c (get_stab_string_offset): Only copy input string if a
1034         fresh copy is needed, not if the section already exists.
1035         (s_stab_generic): Cache stab section name to bypass lookups, since
1036         usually it will match.  Could be made faster still by changing the
1037         memory allocation rules.
1038         (s_xstab): Cache section name to bypass repeated string
1039         allocation.
1040
1041         * frags.c (frag_new): Deleted register declarations.
1042
1043         * listing.c (frag_now): Don't declare.
1044
1045         * as.c (chunksize): New variable.
1046         (debug_memory): New variable.
1047         (main): If debug_memory is set, reduce chunksize and
1048         _bfd_chunksize.
1049         * as.h (chunksize): Declare it.
1050         * read.c (read_begin): Use it.
1051
1052         * config/tc-alpha.c (md_shortopts): Include 'g'.
1053         (md_parse_option): Ignore it.
1054
1055         * Makefile.in (distclean): Remove Makefile and config.status from
1056         testsuite directory.
1057         (clean-here): Don't delete testsuite.  Instead, delete only the
1058         files within it that would be generated by running tests.
1059
1060         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1061         frag_now_fix instead of accessing obstack info directly.
1062         * config/tc-arm.c (s_ltorg): Ditto.
1063         (md_assemble): Ditto.
1064
1065         * config/tc-i386.c (md_assemble): Call frag_grow instead of
1066         obstack_room.

1069
1070         * stabs.c (aout_process_stab): Insert debug symbol into symbol
1071         chain after parsing value expression, if any, to avoid separating
1072         continued .stabs lines.
1073
1074 Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>

1080
1081         * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
1082         -mcom support and PPC_OPCODE_ANY for -many.
1083         (md_parse_option): Ditto.
1084         (ppc_arch): Ditto.
1085         (md_begin): For duplicate instructions, print all duplicates
1086         before aborting.

1091         common mode operation.
1092         (md_show_usage): Add -mcom to usage message.

1111         the fix_line field.
1112         * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and

1150
1151         * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
