--- Comment #133 from Richard Biener <rguenth at gcc dot gnu.org> --- Thanks for the update - this PR (one of the testcases) is also tracked in http://gcc.opensuse.org/c++bench-czerny/random/ (two testcases, pr26854.c is "all.c" and pr26854-2.c is "_num.c"). note that our focus is primarily -O1 for this kind of testcases - -O2 contains too many known quadraticnesses though _num.c seems to survive fine (well, ~2gb of ram).
