   2
   3         * as.c (main): Move md_end call to just after call to
   4         perform_an_assembly_pass.  Delete cpu-specific code here.

   6 start-sanitize-rce
   7         * config/tc-rce.c (md_end): Deleted.
   8         * config/tc-rce.h (md_end): New macro, calls dump_literals.

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

 278         accepting the 4100 as a MIPS architecture variant (md_begin,
 279         macro_build, mips_ip, md_parse_option). Adding suitable
 280         command-line OPTIONs, and updating the help text (md_show_usage).
 281
 282 Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>
 283
 284         * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
 285         BFD_ASSEMBLER is defined.
 286
 287         * Use one active frag and one obstack per frag chain:
 288         * frags.c (frags): Variable deleted.
 289         (frag_alloc): New function.
 290         (frag_grow, frag_more, frag_variant, frag_now_fix,
 291         frag_append_1_char): Refer to frchain_now->frch_obstack instead of
 292         frags variable.
 293         (frag_new): Ditto.  Verify that frch_last and frag_now match on
 294         entry and exit, and that old frag_now has non-zero type.  Replace
 295         "know" uses with "assert".  Use frag_alloc instead of mucking with
 296         obstack alignment.
 297         * frags.h (frags): Declaration deleted.
 298         * subsegs.h (struct frchain): Add new field frch_frag_now.

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