Log message:
http://gcc.gnu.org/ml/gcc-patches/2003-07/msg00197.html
* ra-build.c (determine_web_costs): Use copy_cost instead assuming
memory move cost or constant cost. Adjust heuristics to deal with
spill temps and zero frequencies. Penalize webs used in compares.
(select_regclass): Reorder loops to first go over all full webs,
and fill subwebs from them separately. Accept empty usable regs
for special webs.
* ra-colorize.c (enough_free_p): New.
(non_conflicting_for_combine): New.
(sort_and_combine_web_pairs): Call both.
(aggressive_coalesce, aggressive_coalesce_fast, extended_coalesce,
extended_coalesce_2, check_uncoalesced_moves): Ditto.
* ra-rewrite.c (spill_coalescing): Call non_conflicting_for_combine.
(spill_prop_savings): Ditto.
* ra.h (non_conflicting_for_combine): Declare.
