2942 md_pcrel_from function, taking an additional section argument.
2943 Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.
2945 * write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
2946 older TC_FORCE_RELOCATION if not defined.
2947 (MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
2948 (fixup_segment): Use MD_PCREL_FROM_SECTION instead of
2949 md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
2950 TC_FORCE_RELOCATION.
2952 Mon Oct 23 16:20:04 1995 Ken Raeburn <raeburn@cygnus.com>

2956 * messages.c (identify): Only print filename if non-null.
2957 (as_show_where): Ditto, for line number too.
2958 (as_warn_internal, as_bad_internal): Ditto.
2960 * input-file.c (input_file_open): If the input file can't be

2965 * config/tc-mips.c: Added mips_4100 control, and support for
2966 accepting the 4100 as a MIPS architecture variant (md_begin,
2967 macro_build, mips_ip, md_parse_option). Adding suitable

2977 (frag_alloc): New function.
2978 (frag_grow, frag_more, frag_variant, frag_now_fix,
2979 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
2981 (frag_new): Ditto. Verify that frch_last and frag_now match on
2982 entry and exit, and that old frag_now has non-zero type. Replace
2983 "know" uses with "assert". Use frag_alloc instead of mucking with
2985 * frags.h (frags): Declaration deleted.
2986 * subsegs.h (struct frchain): Add new field frch_frag_now.
2987 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static

2993 (subseg_set_rest): Save and restore frag_now in frch_frag_now
2994 field of frchainS. Don't create new frags on section switch, and
2995 use frag_alloc when creating a new frag chain. For absolute
2996 section, set frchain_now to absolute_frchain. Verify that
2997 frch_last and frag_now match on entry and exit. Initialize
2998 per-chain obstack, and under gcc, set required alignment to that
2999 needed by fragS structure.

3007 memory allocation rules.
3008 (s_xstab): Cache section name to bypass repeated string
3011 * frags.c (frag_new): Deleted register declarations.
3013 * listing.c (frag_now): Don't declare.
3015 * as.c (chunksize): New variable.

3046 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
3047 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
3049 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>

3052 -mcom support and PPC_OPCODE_ANY for -many.
3053 (md_parse_option): Ditto.
3055 (md_begin): For duplicate instructions, print all duplicates

3114 * doc/c-ns32k.texi: New file.
3116 * sb.c, macro.c: Include string.h.
3118 * Makefile.in (comparison): Only check *.o; we don't care if
3119 timestamps inserted by the native linker differ.
3121 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
3122 if alignment stricter than 4 bytes is requested; in that case,
