   2
   3         * config/obj-coff.c (write_object_file): Change use of md_do_align

  13 start-sanitize-rce
  14         * config/tc-rce.c (md_end): Deleted.
  15         * config/tc-rce.h (md_end): New macro, calls dump_literals.

  38         generate optimal multi-byte nop instructions for ".align n"
  39         ".align n,0x90", and aligns requiring more than 15 bytes of
  40         padding still generate multiple 0x90's as before.

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

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