522 * config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
523 TC_FORCE_RELOCATION, taking an additional section argument. If
524 the section of the target symbol is not the same as the current
525 section, always force the relocation to be used.
526 (MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.
528 * config/tc-ppc.c (md_pcrel_from_section): Rename from the
529 md_pcrel_from function, taking an additional section argument.
530 Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.
532 * write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
533 older TC_FORCE_RELOCATION if not defined.
534 (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
535 (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
536 md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
539 Mon Oct 23 16:20:04 1995 Ken Raeburn <raeburn@cygnus.com>
541 * input-scrub.c (as_where): Set name to null pointer if we don't

553 accepting the 4100 as a MIPS architecture variant (md_begin,
554 macro_build, mips_ip, md_parse_option). Adding suitable
555 command-line OPTIONs, and updating the help text (md_show_usage).

572 * frags.h (frags): Declaration deleted.
573 * subsegs.h (struct frchain): Add new field frch_frag_now.
574 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
576 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
577 give it any stricter alignment than frchainS structures need. Do
578 not initialize frags obstack. Set frag_now to point to
579 dummy_obstack. Initialize absolute_frchain.
580 (subseg_set_rest): Save and restore frag_now in frch_frag_now
581 field of frchainS. Don't create new frags on section switch, and
582 use frag_alloc when creating a new frag chain. For absolute
583 section, set frchain_now to absolute_frchain. Verify that
584 frch_last and frag_now match on entry and exit. Initialize
585 per-chain obstack, and under gcc, set required alignment to that
586 needed by fragS structure.

610 (md_parse_option): Ignore it.
612 * Makefile.in (distclean): Remove Makefile and config.status from
614 (clean-here): Don't delete testsuite. Instead, delete only the
615 files within it that would be generated by running tests.
617 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
618 frag_now_fix instead of accessing obstack info directly.

633 * config/tc-mips.c (mips_elf_pseudo_table): Remove.

638 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
639 -mcom support and PPC_OPCODE_ANY for -many.

675 Mon Sep 25 22:49:32 1995 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
677 * configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.
679 * config/obj-elf.c (obj_elf_common): Convert specified byte
680 alignment to power of two. Set size of local bss symbol.

700 despite its being commented out for now.
701 * doc/c-ns32k.texi: New file.
703 * sb.c, macro.c: Include string.h.
705 * Makefile.in (comparison): Only check *.o; we don't care if
706 timestamps inserted by the native linker differ.
708 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
709 if alignment stricter than 4 bytes is requested; in that case,
710 align to a 4-byte boundary first.

714 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used
