4363 * Use one active frag and one obstack per frag chain:
4364 * frags.c (frags): Variable deleted.
4365 (frag_alloc): New function.
4366 (frag_grow, frag_more, frag_variant, frag_now_fix,
4367 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
4369 (frag_new): Ditto. Verify that frch_last and frag_now match on
4370 entry and exit, and that old frag_now has non-zero type. Replace
4371 "know" uses with "assert". Use frag_alloc instead of mucking with
4373 * frags.h (frags): Declaration deleted.
4374 * subsegs.h (struct frchain): Add new field frch_frag_now.
4375 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
4377 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
4378 give it any stricter alignment than frchainS structures need. Do
4379 not initialize frags obstack. Set frag_now to point to
4380 dummy_obstack. Initialize absolute_frchain.
4381 (subseg_set_rest): Save and restore frag_now in frch_frag_now
4382 field of frchainS. Don't create new frags on section switch, and
4383 use frag_alloc when creating a new frag chain. For absolute
4384 section, set frchain_now to absolute_frchain. Verify that
4385 frch_last and frag_now match on entry and exit. Initialize
4386 per-chain obstack, and under gcc, set required alignment to that
4387 needed by fragS structure.
4389 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
4391 * stabs.c (get_stab_string_offset): Only copy input string if a
4392 fresh copy is needed, not if the section already exists.
4393 (s_stab_generic): Cache stab section name to bypass lookups, since
4394 usually it will match. Could be made faster still by changing the
4395 memory allocation rules.
4396 (s_xstab): Cache section name to bypass repeated string
4399 * frags.c (frag_new): Deleted register declarations.
4401 * listing.c (frag_now): Don't declare.
4403 * as.c (chunksize): New variable.
4404 (debug_memory): New variable.
4405 (main): If debug_memory is set, reduce chunksize and

4408 * read.c (read_begin): Use it.
4410 * config/tc-alpha.c (md_shortopts): Include 'g'.
4411 (md_parse_option): Ignore it.
4413 * Makefile.in (distclean): Remove Makefile and config.status from
4414 testsuite directory.
4415 (clean-here): Don't delete testsuite. Instead, delete only the
4416 files within it that would be generated by running tests.
4418 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
4419 frag_now_fix instead of accessing obstack info directly.
4420 * config/tc-arm.c (s_ltorg): Ditto.
4421 (md_assemble): Ditto.
4423 * config/tc-i386.c (md_assemble): Call frag_grow instead of
4426 Wed Oct 18 12:22:59 1995 Ken Raeburn <raeburn@cygnus.com>
4428 * stabs.c (aout_process_stab): Insert debug symbol into symbol
4429 chain after parsing value expression, if any, to avoid separating
4430 continued .stabs lines.
4432 Mon Oct 16 10:56:41 1995 Ian Lance Taylor <ian@cygnus.com>
4434 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
4435 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
4437 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>
4439 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
4440 -mcom support and PPC_OPCODE_ANY for -many.
4441 (md_parse_option): Ditto.
4443 (md_begin): For duplicate instructions, print all duplicates
4446 Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com>
4448 * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
4449 common mode operation.
4450 (md_show_usage): Add -mcom to usage message.
4452 Fri Oct 13 13:32:45 1995 steve chamberlain <sac@slash.cygnus.com>
4454 * expr.c (op_rank): Add O_symbol_rva.
4455 * expr.h (operatorT): Add O_symbol_rva.
4456 * read.c (cons_worker): Set O_symbol_rva when necessary.
4457 * write.c (fix_new_exp): Understand O_symbol_rva.
4459 Tue Oct 10 11:34:14 1995 Ian Lance Taylor <ian@cygnus.com>
4461 * config/tc-mips.c: Correct s_cons arguments. From Michael
4462 Joosten <joost@ori.cadlab.de>.
4464 Mon Oct 9 19:59:53 1995 Ian Lance Taylor <ian@cygnus.com>
4466 * config/tc-ppc.c (ppc_macro): Make count unsigned.
4467 (ppc_biei): Set segment to now_seg and value to coff_n_line_nos.
4468 (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
4470 * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
4471 make non-static. Change all users.
4472 * config/obj-coff.h (coff_n_line_nos): Declare.

4476 Mon Sep 25 22:49:32 1995 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
4478 * configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.
4480 * config/obj-elf.c (obj_elf_common): Convert specified byte
4481 alignment to power of two. Set size of local bss symbol.

4485 Fri Oct 6 15:22:25 1995 Ian Lance Taylor <ian@cygnus.com>
4487 * sb.c, macro.c: Decide whether to include <string.h> or
4488 <strings.h> just as as.h does.
4490 Fri Oct 6 09:55:33 1995 Doug Evans <dje@canuck.cygnus.com>
4492 * Makefile.in (site.exp): Fix setting of $srcdir.

4500 * doc/as.texinfo: Split out the NS32k family documentation,
4501 despite its being commented out for now.
4502 * doc/c-ns32k.texi: New file.
4504 * sb.c, macro.c: Include string.h.
4506 * Makefile.in (comparison): Only check *.o; we don't care if
4507 timestamps inserted by the native linker differ.
4509 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
4510 if alignment stricter than 4 bytes is requested; in that case,
4511 align to a 4-byte boundary first.
4513 Thu Sep 28 19:35:27 1995 Pat Rankin <rankin@eql.caltech.edu>
4515 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used

4521 qualifiers and detect errors if present.

4533 * config/tc-m68k.c (isword): Accept all values from -65536 to
4534 +65535, so ~VAL will not be rejected.
