Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- GCC has a heustrics for deciding on non-temporal stores or not (when used with -fprefetch-loop-arrays) but it is hard not hit it sometimes. Anyways closing as invalid as we do have 2 testcases in the testsuite that detects nontemporal stores, gcc.dg/tree-ssa/prefetch-{8,9}.c and they still pass.
