  43         padding still generate multiple 0x90's as before.

 273
 274 Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>

 288         accepting the 4100 as a MIPS architecture variant (md_begin,
 289         macro_build, mips_ip, md_parse_option). Adding suitable
 290         command-line OPTIONs, and updating the help text (md_show_usage).
 291
 292 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
 293
 294         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
 295         BFD_ASSEMBLER is defined.
 296
 297         * Use one active frag and one obstack per frag chain:
 298         * frags.c (frags): Variable deleted.
 299         (frag_alloc): New function.
 300         (frag_grow, frag_more, frag_variant, frag_now_fix,
 301         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
 302         frags variable.
 303         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 304         entry and exit, and that old frag_now has non-zero type.  Replace
 305         "know" uses with "assert".  Use frag_alloc instead of mucking with
 306         obstack alignment.
 307         * frags.h (frags): Declaration deleted.
 308         * subsegs.h (struct frchain): Add new field frch_frag_now.

 310         variables.
 311         (subsegs_begin): Initialize frchains obstack.  Under gcc, don't
 312         give it any stricter alignment than frchainS structures need.  Do
 313         not initialize frags obstack.  Set frag_now to point to
 314         dummy_obstack.  Initialize absolute_frchain.
 315         (subseg_set_rest): Save and restore frag_now in frch_frag_now
 316         field of frchainS.  Don't create new frags on section switch, and
 317         use frag_alloc when creating a new frag chain.  For absolute
 318         section, set frchain_now to absolute_frchain.  Verify that
 319         frch_last and frag_now match on entry and exit.  Initialize
 320         per-chain obstack, and under gcc, set required alignment to that
 321         needed by fragS structure.
 322
 323         * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
 324
 325         * stabs.c (get_stab_string_offset): Only copy input string if a
 326         fresh copy is needed, not if the section already exists.
 327         (s_stab_generic): Cache stab section name to bypass lookups, since
 328         usually it will match.  Could be made faster still by changing the
 329         memory allocation rules.
 330         (s_xstab): Cache section name to bypass repeated string
 331         allocation.
 332
