Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Shouldn't you cache the result of count_num_stmt in some SSA_NAME_VERSION indexed vector? Otherwise it can be expensive on pathological testcases. And with the caching I'd hope it should be cheap enough that you could do that even outside of loops.
