2431 (as_show_where): Ditto, for line number too.
2432 (as_warn_internal, as_bad_internal): Ditto.
2434 * input-file.c (input_file_open): If the input file can't be
2435 opened, consider it an error.

2439 * config/tc-mips.c: Added mips_4100 control, and support for
2440 accepting the 4100 as a MIPS architecture variant (md_begin,
2441 macro_build, mips_ip, md_parse_option). Adding suitable
2442 command-line OPTIONs, and updating the help text (md_show_usage).

2446 * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
2447 BFD_ASSEMBLER is defined.
2449 * Use one active frag and one obstack per frag chain:
2450 * frags.c (frags): Variable deleted.
2451 (frag_alloc): New function.
2452 (frag_grow, frag_more, frag_variant, frag_now_fix,
2453 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
2455 (frag_new): Ditto. Verify that frch_last and frag_now match on
2456 entry and exit, and that old frag_now has non-zero type. Replace
2457 "know" uses with "assert". Use frag_alloc instead of mucking with
2459 * frags.h (frags): Declaration deleted.
2460 * subsegs.h (struct frchain): Add new field frch_frag_now.
2461 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
2463 (subsegs_begin): Initialize frchains obstack. Under gcc, don't

2467 (subseg_set_rest): Save and restore frag_now in frch_frag_now
2468 field of frchainS. Don't create new frags on section switch, and
2469 use frag_alloc when creating a new frag chain. For absolute
2470 section, set frchain_now to absolute_frchain. Verify that
2471 frch_last and frag_now match on entry and exit. Initialize
2472 per-chain obstack, and under gcc, set required alignment to that
2473 needed by fragS structure.
2475 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
2477 * stabs.c (get_stab_string_offset): Only copy input string if a
2478 fresh copy is needed, not if the section already exists.

2481 memory allocation rules.
2482 (s_xstab): Cache section name to bypass repeated string
2485 * frags.c (frag_new): Deleted register declarations.
2487 * listing.c (frag_now): Don't declare.
2489 * as.c (chunksize): New variable.
2490 (debug_memory): New variable.

2499 * Makefile.in (distclean): Remove Makefile and config.status from
2500 testsuite directory.

2505 frag_now_fix instead of accessing obstack info directly.
2506 * config/tc-arm.c (s_ltorg): Ditto.
2507 (md_assemble): Ditto.
2509 * config/tc-i386.c (md_assemble): Call frag_grow instead of

2514 * stabs.c (aout_process_stab): Insert debug symbol into symbol
2515 chain after parsing value expression, if any, to avoid separating
2516 continued .stabs lines.
2518 Mon Oct 16 10:56:41 1995 Ian Lance Taylor <ian@cygnus.com>
2520 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
2521 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
2523 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>
2525 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
2526 -mcom support and PPC_OPCODE_ANY for -many.
2527 (md_parse_option): Ditto.
2529 (md_begin): For duplicate instructions, print all duplicates
2532 Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com>
2534 * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
2535 common mode operation.
2536 (md_show_usage): Add -mcom to usage message.
2538 Fri Oct 13 13:32:45 1995 steve chamberlain <sac@slash.cygnus.com>

2552 * config/tc-ppc.c (ppc_macro): Make count unsigned.
2553 (ppc_biei): Set segment to now_seg and value to coff_n_line_nos.
2554 (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
2556 * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
2557 make non-static. Change all users.
2558 * config/obj-coff.h (coff_n_line_nos): Declare.

2586 * doc/as.texinfo: Split out the NS32k family documentation,
2587 despite its being commented out for now.
2588 * doc/c-ns32k.texi: New file.
2590 * sb.c, macro.c: Include string.h.
2592 * Makefile.in (comparison): Only check *.o; we don't care if
2593 timestamps inserted by the native linker differ.
2595 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
2596 if alignment stricter than 4 bytes is requested; in that case,
2597 align to a 4-byte boundary first.
2599 Thu Sep 28 19:35:27 1995 Pat Rankin <rankin@eql.caltech.edu>
2601 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used

2606 * config/tc-ppc.c (parse_toc_entry): New function to parse [toc]
2607 qualifiers and detect errors if present.
