 682
 683         * config/tc-hppa.c (md_pseudo_table): Add new ".nsubspa" opcode.
 684         (pa_subspace): For ".nsubspa", always create a new subspace
 685         with the given attributes, even if one already exists with the
 686         same name.

 688 Tue Oct 24 14:50:38 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
 689
 690         * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
 691         TC_FORCE_RELOCATION, taking an additional section argument.  If
 692         the section of the target symbol is not the same as the current
 693         section, always force the relocation to be used.
 694         (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
 695
 696         * config/tc-ppc.c (md_pcrel_from_section): Rename from the
 697         md_pcrel_from function, taking an additional section argument.
 698         Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.
 699
 700         * write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
 701         older TC_FORCE_RELOCATION if not defined.
 702         (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
 703         (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
 704         md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
 705         TC_FORCE_RELOCATION.

 707 Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>
 708
 709         * input-scrub.c (as_where): Set name to null pointer if we don't
 710         have a file name.
 711         * messages.c (identify): Only print filename if non-null.
 712         (as_show_where): Ditto, for line number too.
 713         (as_warn_internal, as_bad_internal): Ditto.
 714
 715         * input-file.c (input_file_open): If the input file can't be
 716         opened, consider it an error.
 717
 718 Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>
 719
 720         * config/tc-mips.c: Added mips_4100 control, and support for
 721         accepting the 4100 as a MIPS architecture variant (md_begin,
 722         macro_build, mips_ip, md_parse_option). Adding suitable
 723         command-line OPTIONs, and updating the help text (md_show_usage).
 724
 725 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
 726
 727         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
 728         BFD_ASSEMBLER is defined.
 729
 730         * Use one active frag and one obstack per frag chain:
 731         * frags.c (frags): Variable deleted.
 732         (frag_alloc): New function.
 733         (frag_grow, frag_more, frag_variant, frag_now_fix,
 734         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
 735         frags variable.
 736         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 737         entry and exit, and that old frag_now has non-zero type.  Replace
 738         "know" uses with "assert".  Use frag_alloc instead of mucking with
 739         obstack alignment.
 740         * frags.h (frags): Declaration deleted.
 741         * subsegs.h (struct frchain): Add new field frch_frag_now.
 742         * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
 743         variables.
 744         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 745         give it any stricter alignment than frchainS structures need.  Do
 746         not initialize frags obstack.  Set frag_now to point to
 747         dummy_obstack.  Initialize absolute_frchain.
 748         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 749         field of frchainS.  Don't create new frags on section switch, and
 750         use frag_alloc when creating a new frag chain.  For absolute
 751         section, set frchain_now to absolute_frchain.  Verify that
 752         frch_last and frag_now match on entry and exit.  Initialize
 753         per-chain obstack, and under gcc, set required alignment to that
 754         needed by fragS structure.
 755
 756         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 757
 758         * stabs.c (get_stab_string_offset): Only copy input string if a
 759         fresh copy is needed, not if the section already exists.
 760         (s_stab_generic): Cache stab section name to bypass lookups, since
 761         usually it will match.  Could be made faster still by changing the
 762         memory allocation rules.
 763         (s_xstab): Cache section name to bypass repeated string
 764         allocation.
 765
 766         * frags.c (frag_new): Deleted register declarations.
 767
 768         * listing.c (frag_now): Don't declare.

 770         * as.c (chunksize): New variable.
 771         (debug_memory): New variable.
 772         (main): If debug_memory is set, reduce chunksize and
 773         _bfd_chunksize.
 774         * as.h (chunksize): Declare it.
 775         * read.c (read_begin): Use it.
 776
 777         * config/tc-alpha.c (md_shortopts): Include 'g'.
 778         (md_parse_option): Ignore it.
 779
 780         * Makefile.in (distclean): Remove Makefile and config.status from
 781         testsuite directory.
 782         (clean-here): Don't delete testsuite.  Instead, delete only the
 783         files within it that would be generated by running tests.
 784
 785         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
 786         frag_now_fix instead of accessing obstack info directly.
 787         * config/tc-arm.c (s_ltorg): Ditto.
 788         (md_assemble): Ditto.
 789
 790         * config/tc-i386.c (md_assemble): Call frag_grow instead of
 791         obstack_room.
 792
 793 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
 794
 795         * stabs.c (aout_process_stab): Insert debug symbol into symbol
 796         chain after parsing value expression, if any, to avoid separating
 797         continued .stabs lines.
 798

 809         (ppc_arch): Ditto.
 810         (md_begin): For duplicate instructions, print all duplicates
 811         before aborting.
