1007 Tue Oct 24 15:21:33 1995  Jeffrey A Law  (law@cygnus.com)
1008
1009         * config/tc-hppa.c (md_pseudo_table): Add new ".nsubspa" opcode.
1010         (pa_subspace): For ".nsubspa", always create a new subspace
1011         with the given attributes, even if one already exists with the
1012         same name.
1013
1014 Tue Oct 24 14:50:38 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
1015
1016         * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
1017         TC_FORCE_RELOCATION, taking an additional section argument.  If
1018         the section of the target symbol is not the same as the current
1019         section, always force the relocation to be used.
1020         (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
1021
1022         * config/tc-ppc.c (md_pcrel_from_section): Rename from the
1023         md_pcrel_from function, taking an additional section argument.
1024         Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.
1025
1026         * write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
1027         older TC_FORCE_RELOCATION if not defined.
1028         (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
1029         (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
1030         md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
1031         TC_FORCE_RELOCATION.

1033 Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>
1034
1035         * input-scrub.c (as_where): Set name to null pointer if we don't
1036         have a file name.
1037         * messages.c (identify): Only print filename if non-null.
1038         (as_show_where): Ditto, for line number too.
1039         (as_warn_internal, as_bad_internal): Ditto.
1040
1041         * input-file.c (input_file_open): If the input file can't be
1042         opened, consider it an error.
1043
1044 Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>
1045
1046         * config/tc-mips.c: Added mips_4100 control, and support for
1047         accepting the 4100 as a MIPS architecture variant (md_begin,
1048         macro_build, mips_ip, md_parse_option). Adding suitable
1049         command-line OPTIONs, and updating the help text (md_show_usage).
1050
1051 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
1052
1053         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
1054         BFD_ASSEMBLER is defined.
1055
1056         * Use one active frag and one obstack per frag chain:
1057         * frags.c (frags): Variable deleted.
1058         (frag_alloc): New function.
1059         (frag_grow, frag_more, frag_variant, frag_now_fix,
1060         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
1061         frags variable.
1062         (frag_new): Ditto.  Verify that frch_last and frag_now match on
1063         entry and exit, and that old frag_now has non-zero type.  Replace
1064         "know" uses with "assert".  Use frag_alloc instead of mucking with
1065         obstack alignment.
1066         * frags.h (frags): Declaration deleted.
1067         * subsegs.h (struct frchain): Add new field frch_frag_now.
1068         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
1069         variables.
1070         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
1071         give it any stricter alignment than frchainS structures need.  Do
1072         not initialize frags obstack.  Set frag_now to point to
1073         dummy_obstack.  Initialize absolute_frchain.
1074         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1075         field of frchainS.  Don't create new frags on section switch, and
1076         use frag_alloc when creating a new frag chain.  For absolute
1077         section, set frchain_now to absolute_frchain.  Verify that
1078         frch_last and frag_now match on entry and exit.  Initialize
1079         per-chain obstack, and under gcc, set required alignment to that
1080         needed by fragS structure.
1081
1082         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1083
1084         * stabs.c (get_stab_string_offset): Only copy input string if a
1085         fresh copy is needed, not if the section already exists.
1086         (s_stab_generic): Cache stab section name to bypass lookups, since
1087         usually it will match.  Could be made faster still by changing the
1088         memory allocation rules.
1089         (s_xstab): Cache section name to bypass repeated string
1090         allocation.
1091
1092         * frags.c (frag_new): Deleted register declarations.
1093
1094         * listing.c (frag_now): Don't declare.
1095
1096         * as.c (chunksize): New variable.
1097         (debug_memory): New variable.
1098         (main): If debug_memory is set, reduce chunksize and
1099         _bfd_chunksize.
1100         * as.h (chunksize): Declare it.
1101         * read.c (read_begin): Use it.
1102
1103         * config/tc-alpha.c (md_shortopts): Include 'g'.
1104         (md_parse_option): Ignore it.
1105
1106         * Makefile.in (distclean): Remove Makefile and config.status from
1107         testsuite directory.
1108         (clean-here): Don't delete testsuite.  Instead, delete only the
1109         files within it that would be generated by running tests.
1110
1111         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1112         frag_now_fix instead of accessing obstack info directly.
1113         * config/tc-arm.c (s_ltorg): Ditto.
1114         (md_assemble): Ditto.
1115
1116         * config/tc-i386.c (md_assemble): Call frag_grow instead of
1117         obstack_room.
1118
1119 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
1120
1121         * stabs.c (aout_process_stab): Insert debug symbol into symbol
1122         chain after parsing value expression, if any, to avoid separating
1123         continued .stabs lines.
1124

1131
1132         * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
1133         -mcom support and PPC_OPCODE_ANY for -many.
1134         (md_parse_option): Ditto.
