4402 (frag_alloc): New function.
4403 (frag_grow, frag_more, frag_variant, frag_now_fix,
4404 frag_append_1_char): Refer to frchain_now->frch_obstack instead of

4407 entry and exit, and that old frag_now has non-zero type. Replace
4408 "know" uses with "assert". Use frag_alloc instead of mucking with
4410 * frags.h (frags): Declaration deleted.
4411 * subsegs.h (struct frchain): Add new field frch_frag_now.
4412 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static

4419 field of frchainS. Don't create new frags on section switch, and
4420 use frag_alloc when creating a new frag chain. For absolute
4421 section, set frchain_now to absolute_frchain. Verify that
4422 frch_last and frag_now match on entry and exit. Initialize

4433 (s_xstab): Cache section name to bypass repeated string
4436 * frags.c (frag_new): Deleted register declarations.
4438 * listing.c (frag_now): Don't declare.
4440 * as.c (chunksize): New variable.

4471 * config/tc-mips.c (mips_elf_pseudo_table): Remove.

4539 * doc/c-ns32k.texi: New file.
4541 * sb.c, macro.c: Include string.h.

4544 timestamps inserted by the native linker differ.
4546 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
4547 if alignment stricter than 4 bytes is requested; in that case,
