re PR rtl-optimization/55154 (ICE: in curr_insn_transform, at lra-constraints.c:2702 with custom flags)
2012-11-09 Vladimir Makarov <vmakarov@redhat.com>
PR tree-optimization/55154
* lra-int.h (LRA_LOSER_COST_FACTOR, LRA_MAX_REJECT): New macros.
* lra.c (setup_operand_alternative): Use them.
* lra-constraints.c (LOSER_COST_FACTOR, MAX_OVERALL_COST_BOUND):
Remove.
(process_alt_operands): Use LRA_LOSER_COST_FACTOR and
LRA_MAX_REJECT. Accumulate reject instead of setting for
non-const.
(curr_insn_transform): Initialize best_losers and best_overall by
INT_MAX.
