5990         * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
5991         TC_FORCE_RELOCATION, taking an additional section argument.  If
5992         the section of the target symbol is not the same as the current
5993         section, always force the relocation to be used.
5994         (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
5995
5996         * config/tc-ppc.c (md_pcrel_from_section): Rename from the
5997         md_pcrel_from function, taking an additional section argument.

6007 Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>
6008
6009         * input-scrub.c (as_where): Set name to null pointer if we don't

6021         accepting the 4100 as a MIPS architecture variant (md_begin,
6022         macro_build, mips_ip, md_parse_option). Adding suitable
6023         command-line OPTIONs, and updating the help text (md_show_usage).
6024
6025 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
6026
6027         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
6028         BFD_ASSEMBLER is defined.
6029
6030         * Use one active frag and one obstack per frag chain:
6031         * frags.c (frags): Variable deleted.
6032         (frag_alloc): New function.
6033         (frag_grow, frag_more, frag_variant, frag_now_fix,
6034         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
6035         frags variable.
6036         (frag_new): Ditto.  Verify that frch_last and frag_now match on
6037         entry and exit, and that old frag_now has non-zero type.  Replace
6038         "know" uses with "assert".  Use frag_alloc instead of mucking with
6039         obstack alignment.
6040         * frags.h (frags): Declaration deleted.
6041         * subsegs.h (struct frchain): Add new field frch_frag_now.

6043         variables.
6044         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
6045         give it any stricter alignment than frchainS structures need.  Do
6046         not initialize frags obstack.  Set frag_now to point to
6047         dummy_obstack.  Initialize absolute_frchain.
6048         (subseg_set_rest): Save and restore frag_now in frch_frag_now
6049         field of frchainS.  Don't create new frags on section switch, and
6050         use frag_alloc when creating a new frag chain.  For absolute
6051         section, set frchain_now to absolute_frchain.  Verify that
6052         frch_last and frag_now match on entry and exit.  Initialize
6053         per-chain obstack, and under gcc, set required alignment to that
6054         needed by fragS structure.
6055
6056         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
6057
6058         * stabs.c (get_stab_string_offset): Only copy input string if a
6059         fresh copy is needed, not if the section already exists.
6060         (s_stab_generic): Cache stab section name to bypass lookups, since
6061         usually it will match.  Could be made faster still by changing the
6062         memory allocation rules.
6063         (s_xstab): Cache section name to bypass repeated string
6064         allocation.
6065
6066         * frags.c (frag_new): Deleted register declarations.
6067
6068         * listing.c (frag_now): Don't declare.

6071         (debug_memory): New variable.
6072         (main): If debug_memory is set, reduce chunksize and
6073         _bfd_chunksize.
6074         * as.h (chunksize): Declare it.
6075         * read.c (read_begin): Use it.
6076
6077         * config/tc-alpha.c (md_shortopts): Include 'g'.

6079
6080         * Makefile.in (distclean): Remove Makefile and config.status from
6081         testsuite directory.
6082         (clean-here): Don't delete testsuite.  Instead, delete only the
6083         files within it that would be generated by running tests.
6084
6085         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
6086         frag_now_fix instead of accessing obstack info directly.
6087         * config/tc-arm.c (s_ltorg): Ditto.
6088         (md_assemble): Ditto.
6089
6090         * config/tc-i386.c (md_assemble): Call frag_grow instead of
6091         obstack_room.

6093 Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>
6094
6095         * stabs.c (aout_process_stab): Insert debug symbol into symbol

6097         continued .stabs lines.
