4361 (frag_grow, frag_more, frag_variant, frag_now_fix,
4362 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
4364 (frag_new): Ditto. Verify that frch_last and frag_now match on
4365 entry and exit, and that old frag_now has non-zero type. Replace
4366 "know" uses with "assert". Use frag_alloc instead of mucking with
4368 * frags.h (frags): Declaration deleted.
4369 * subsegs.h (struct frchain): Add new field frch_frag_now.
4370 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
4372 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
4373 give it any stricter alignment than frchainS structures need. Do
4374 not initialize frags obstack. Set frag_now to point to
4375 dummy_obstack. Initialize absolute_frchain.
4376 (subseg_set_rest): Save and restore frag_now in frch_frag_now
4377 field of frchainS. Don't create new frags on section switch, and
4378 use frag_alloc when creating a new frag chain. For absolute
4379 section, set frchain_now to absolute_frchain. Verify that
4380 frch_last and frag_now match on entry and exit. Initialize
4381 per-chain obstack, and under gcc, set required alignment to that
4382 needed by fragS structure.
4384 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
4386 * stabs.c (get_stab_string_offset): Only copy input string if a
4387 fresh copy is needed, not if the section already exists.

4389 usually it will match. Could be made faster still by changing the
4390 memory allocation rules.
4391 (s_xstab): Cache section name to bypass repeated string
4394 * frags.c (frag_new): Deleted register declarations.
4396 * listing.c (frag_now): Don't declare.
4398 * as.c (chunksize): New variable.
4399 (debug_memory): New variable.

4405 * config/tc-alpha.c (md_shortopts): Include 'g'.
4406 (md_parse_option): Ignore it.
4408 * Makefile.in (distclean): Remove Makefile and config.status from
4409 testsuite directory.

4411 files within it that would be generated by running tests.
4413 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
4414 frag_now_fix instead of accessing obstack info directly.

4416 (md_assemble): Ditto.
4418 * config/tc-i386.c (md_assemble): Call frag_grow instead of
4421 Wed Oct 18 12:22:59 1995 Ken Raeburn <raeburn@cygnus.com>
4423 * stabs.c (aout_process_stab): Insert debug symbol into symbol
4424 chain after parsing value expression, if any, to avoid separating
4425 continued .stabs lines.
4427 Mon Oct 16 10:56:41 1995 Ian Lance Taylor <ian@cygnus.com>
4429 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
4430 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
4432 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>
4434 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
4435 -mcom support and PPC_OPCODE_ANY for -many.
4436 (md_parse_option): Ditto.
4438 (md_begin): For duplicate instructions, print all duplicates
4441 Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com>
4443 * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
4444 common mode operation.
4445 (md_show_usage): Add -mcom to usage message.
4447 Fri Oct 13 13:32:45 1995 steve chamberlain <sac@slash.cygnus.com>
4449 * expr.c (op_rank): Add O_symbol_rva.
4450 * expr.h (operatorT): Add O_symbol_rva.
4451 * read.c (cons_worker): Set O_symbol_rva when necessary.
4452 * write.c (fix_new_exp): Understand O_symbol_rva.
4454 Tue Oct 10 11:34:14 1995 Ian Lance Taylor <ian@cygnus.com>
4456 * config/tc-mips.c: Correct s_cons arguments. From Michael
4457 Joosten <joost@ori.cadlab.de>.

4461 * config/tc-ppc.c (ppc_macro): Make count unsigned.
4462 (ppc_biei): Set segment to now_seg and value to coff_n_line_nos.
4463 (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
4465 * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
4466 make non-static. Change all users.
4467 * config/obj-coff.h (coff_n_line_nos): Declare.

4471 Mon Sep 25 22:49:32 1995 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
4473 * configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.
4475 * config/obj-elf.c (obj_elf_common): Convert specified byte
4476 alignment to power of two. Set size of local bss symbol.

4480 Fri Oct 6 15:22:25 1995 Ian Lance Taylor <ian@cygnus.com>
4482 * sb.c, macro.c: Decide whether to include <string.h> or
4483 <strings.h> just as as.h does.
4485 Fri Oct 6 09:55:33 1995 Doug Evans <dje@canuck.cygnus.com>

4497 * doc/c-ns32k.texi: New file.
4499 * sb.c, macro.c: Include string.h.
4501 * Makefile.in (comparison): Only check *.o; we don't care if
4502 timestamps inserted by the native linker differ.
4504 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
4505 if alignment stricter than 4 bytes is requested; in that case,
4506 align to a 4-byte boundary first.
4508 Thu Sep 28 19:35:27 1995 Pat Rankin <rankin@eql.caltech.edu>
4510 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used

4516 qualifiers and detect errors if present.
