 694         (pa_subspace): For ".nsubspa", always create a new subspace
 695         with the given attributes, even if one already exists with the
 696         same name.

 698 Tue Oct 24 14:50:38 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 699
 700         * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
 701         TC_FORCE_RELOCATION, taking an additional section argument.  If
 702         the section of the target symbol is not the same as the current
 703         section, always force the relocation to be used.
 704         (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
 705
 706         * config/tc-ppc.c (md_pcrel_from_section): Rename from the
 707         md_pcrel_from function, taking an additional section argument.
 708         Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.
 709
 710         * write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
 711         older TC_FORCE_RELOCATION if not defined.
 712         (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
 713         (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
 714         md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
 715         TC_FORCE_RELOCATION.

 717 Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>
 718
 719         * input-scrub.c (as_where): Set name to null pointer if we don't
 720         have a file name.
 721         * messages.c (identify): Only print filename if non-null.
 722         (as_show_where): Ditto, for line number too.
 723         (as_warn_internal, as_bad_internal): Ditto.
 724
 725         * input-file.c (input_file_open): If the input file can't be
 726         opened, consider it an error.
 727
 728 Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>
 729
 730         * config/tc-mips.c: Added mips_4100 control, and support for
 731         accepting the 4100 as a MIPS architecture variant (md_begin,
 732         macro_build, mips_ip, md_parse_option). Adding suitable
 733         command-line OPTIONs, and updating the help text (md_show_usage).
 734
 735 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
 736
 737         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
 738         BFD_ASSEMBLER is defined.
 739
 740         * Use one active frag and one obstack per frag chain:
 741         * frags.c (frags): Variable deleted.
 742         (frag_alloc): New function.
 743         (frag_grow, frag_more, frag_variant, frag_now_fix,
 744         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
 745         frags variable.
 746         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 747         entry and exit, and that old frag_now has non-zero type.  Replace
 748         "know" uses with "assert".  Use frag_alloc instead of mucking with
 749         obstack alignment.
 750         * frags.h (frags): Declaration deleted.
 751         * subsegs.h (struct frchain): Add new field frch_frag_now.

 753         variables.
 754         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 755         give it any stricter alignment than frchainS structures need.  Do
 756         not initialize frags obstack.  Set frag_now to point to
 757         dummy_obstack.  Initialize absolute_frchain.
 758         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 759         field of frchainS.  Don't create new frags on section switch, and
 760         use frag_alloc when creating a new frag chain.  For absolute
 761         section, set frchain_now to absolute_frchain.  Verify that
 762         frch_last and frag_now match on entry and exit.  Initialize
 763         per-chain obstack, and under gcc, set required alignment to that
 764         needed by fragS structure.
 765
 766         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 767
 768         * stabs.c (get_stab_string_offset): Only copy input string if a
 769         fresh copy is needed, not if the section already exists.
 770         (s_stab_generic): Cache stab section name to bypass lookups, since
 771         usually it will match.  Could be made faster still by changing the
 772         memory allocation rules.
 773         (s_xstab): Cache section name to bypass repeated string
 774         allocation.
 775
 776         * frags.c (frag_new): Deleted register declarations.
 777
 778         * listing.c (frag_now): Don't declare.

 780         * as.c (chunksize): New variable.
 781         (debug_memory): New variable.
 782         (main): If debug_memory is set, reduce chunksize and
 783         _bfd_chunksize.
 784         * as.h (chunksize): Declare it.
 785         * read.c (read_begin): Use it.
 786
 787         * config/tc-alpha.c (md_shortopts): Include 'g'.
 788         (md_parse_option): Ignore it.
 789
 790         * Makefile.in (distclean): Remove Makefile and config.status from
 791         testsuite directory.
 792         (clean-here): Don't delete testsuite.  Instead, delete only the
 793         files within it that would be generated by running tests.
 794
 795         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 796         frag_now_fix instead of accessing obstack info directly.
 797         * config/tc-arm.c (s_ltorg): Ditto.
 798         (md_assemble): Ditto.
 799
 800         * config/tc-i386.c (md_assemble): Call frag_grow instead of
 801         obstack_room.
 802
 803 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
 804
 805         * stabs.c (aout_process_stab): Insert debug symbol into symbol
 806         chain after parsing value expression, if any, to avoid separating
 807         continued .stabs lines.
 808
 809 Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>

 818         (md_parse_option): Ditto.
 819         (ppc_arch): Ditto.
 820         (md_begin): For duplicate instructions, print all duplicates
 821         before aborting.
