4195 (frag_alloc): New function.
4196 (frag_grow, frag_more, frag_variant, frag_now_fix,
4197 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
4198 frags variable.
4199 (frag_new): Ditto. Verify that frch_last and frag_now match on
4200 entry and exit, and that old frag_now has non-zero type. Replace
4201 "know" uses with "assert". Use frag_alloc instead of mucking with
4202 obstack alignment.
4203 * frags.h (frags): Declaration deleted.
4204 * subsegs.h (struct frchain): Add new field frch_frag_now.
4205 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
4206 variables.
4207 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
4208 give it any stricter alignment than frchainS structures need. Do
4209 not initialize frags obstack. Set frag_now to point to
4210 dummy_obstack. Initialize absolute_frchain.
4211 (subseg_set_rest): Save and restore frag_now in frch_frag_now
4212 field of frchainS. Don't create new frags on section switch, and
4213 use frag_alloc when creating a new frag chain. For absolute
4214 section, set frchain_now to absolute_frchain. Verify that
4215 frch_last and frag_now match on entry and exit. Initialize
4216 per-chain obstack, and under gcc, set required alignment to that
4217 needed by fragS structure.
4218
4219 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
4220
4221 * stabs.c (get_stab_string_offset): Only copy input string if a
4222 fresh copy is needed, not if the section already exists.
4223 (s_stab_generic): Cache stab section name to bypass lookups, since
4224 usually it will match. Could be made faster still by changing the
4225 memory allocation rules.
4226 (s_xstab): Cache section name to bypass repeated string
4227 allocation.
4228
4229 * frags.c (frag_new): Deleted register declarations.
4230
4231 * listing.c (frag_now): Don't declare.

4236 _bfd_chunksize.
4237 * as.h (chunksize): Declare it.
4238 * read.c (read_begin): Use it.
4239

4242
4243 * Makefile.in (distclean): Remove Makefile and config.status from
4244 testsuite directory.

4246 files within it that would be generated by running tests.
4247
4248 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
4249 frag_now_fix instead of accessing obstack info directly.
4250 * config/tc-arm.c (s_ltorg): Ditto.
4251 (md_assemble): Ditto.
4252
4253 * config/tc-i386.c (md_assemble): Call frag_grow instead of
4254 obstack_room.

4274 before aborting.
