* rtlanal.c (insn_rtx_cost): New function, moved and renamed from combine.c's combine_insn_cost. * rtl.h (insn_rtx_cost): Prototype here. * combine.c (combine_insn_cost): Delete function. (combine_validate_cost): Update callers of combine_insn_cost to call insn_rtx_cost instead. (combine_instructions): Likewise. Use NONJUMP_INSN_P to avoid requesting the rtx_cost of call and/or jump instructions. * ifcvt.c (total_bb_rtx_cost): Use insn_rtx_cost instead of calling rtx_cost directly. Don't request/use the cost of call or jump instructions. Return -1 if the cost of any instruction can't be determined (or the BB contains a function call). (find_if_case_1): Abort transformation if total_bb_rtx_cost returns -1 (i.e. can't determine the cost of any instruction or the basic block contains a subroutine call). (find_if_case_2): Likewise.
