------- Comment #7 from steven at gcc dot gnu dot org 2006-09-18 04:15 ------- To cut down the estimate for the loop size, you need to treat CALL_EXPRs to machine specific builtins specially (and probably some of the normal builtins too). See estimate_num_insns_1, the case for CALL_EXPR. You probably need to add a target hook to make this work. This has been discussed before on the mailing lists.
