        the section of the target symbol is not the same as the current
        section, always force the relocation to be used.
        (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.

        * config/tc-ppc.c (md_pcrel_from_section): Rename from the
        md_pcrel_from function, taking an additional section argument.
        Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.

        * write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
        older TC_FORCE_RELOCATION if not defined.
        (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
        (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
        md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
        TC_FORCE_RELOCATION.
        
Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>

        * input-scrub.c (as_where): Set name to null pointer if we don't
        have a file name.
        * messages.c (identify): Only print filename if non-null.
        (as_show_where): Ditto, for line number too.
        (as_warn_internal, as_bad_internal): Ditto.

        * input-file.c (input_file_open): If the input file can't be
        opened, consider it an error.

Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>

        * config/tc-mips.c: Added mips_4100 control, and support for
        accepting the 4100 as a MIPS architecture variant (md_begin,
        macro_build, mips_ip, md_parse_option). Adding suitable
        command-line OPTIONs, and updating the help text (md_show_usage).
        
Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>

        * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
        BFD_ASSEMBLER is defined.

        * Use one active frag and one obstack per frag chain:
        * frags.c (frags): Variable deleted.
        (frag_alloc): New function.
        (frag_grow, frag_more, frag_variant, frag_now_fix,
        frag_append_1_char): Refer to frchain_now->frch_obstack instead of
        frags variable.
        (frag_new): Ditto.  Verify that frch_last and frag_now match on
        entry and exit, and that old frag_now has non-zero type.  Replace
        "know" uses with "assert".  Use frag_alloc instead of mucking with
        obstack alignment.
        * frags.h (frags): Declaration deleted.
        * subsegs.h (struct frchain): Add new field frch_frag_now.
        * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
        variables.
        (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
        give it any stricter alignment than frchainS structures need.  Do
        not initialize frags obstack.  Set frag_now to point to
        dummy_obstack.  Initialize absolute_frchain.
        (subseg_set_rest): Save and restore frag_now in frch_frag_now
        field of frchainS.  Don't create new frags on section switch, and
        use frag_alloc when creating a new frag chain.  For absolute
        section, set frchain_now to absolute_frchain.  Verify that
        frch_last and frag_now match on entry and exit.  Initialize
        per-chain obstack, and under gcc, set required alignment to that
        needed by fragS structure.

        * write.c (chain_frchains_together_1): Verify fr_type is nonzero.

        * stabs.c (get_stab_string_offset): Only copy input string if a
        fresh copy is needed, not if the section already exists.
        (s_stab_generic): Cache stab section name to bypass lookups, since
        usually it will match.  Could be made faster still by changing the
        memory allocation rules.
        (s_xstab): Cache section name to bypass repeated string
        allocation.

        * frags.c (frag_new): Deleted register declarations.

        * listing.c (frag_now): Don't declare.

        * as.c (chunksize): New variable.
        (debug_memory): New variable.
        (main): If debug_memory is set, reduce chunksize and
        _bfd_chunksize.
        * as.h (chunksize): Declare it.
        * read.c (read_begin): Use it.

        * config/tc-alpha.c (md_shortopts): Include 'g'.
        (md_parse_option): Ignore it.

        * Makefile.in (distclean): Remove Makefile and config.status from
        testsuite directory.
        (clean-here): Don't delete testsuite.  Instead, delete only the
        files within it that would be generated by running tests.

        * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
        frag_now_fix instead of accessing obstack info directly.
        * config/tc-arm.c (s_ltorg): Ditto.
        (md_assemble): Ditto.

        * config/tc-i386.c (md_assemble): Call frag_grow instead of
        obstack_room.

Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>

        * stabs.c (aout_process_stab): Insert debug symbol into symbol
        chain after parsing value expression, if any, to avoid separating
        continued .stabs lines.

Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>

        * config/tc-mips.c (mips_elf_pseudo_table): Remove.
        (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.

Mon Oct 16 07:07:37 1995  Michael Meissner  <meissner@wogglebug.tiac.net>

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

        * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
        common mode operation.
        (md_show_usage): Add -mcom to usage message.

        (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
        the fix_line field.

        timestamps inserted by the native linker differ.

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