I am testing vectorization on the following test case: float x[1024], y[1024]; void myloop1() { for (long int k = 0; k < 512; k++) { x[2*k] = x[2*k]+y[k]; } } Vectorization failed due to "unsafe dependent memory operation". I traced the LoopAccessAnalysis.cpp and found the reason is the NoWrapFlag for SCEVAddRecExpr is not set and consequently the

...h major regressions like this (it doesn't exactly track memory usage directly, but it does a half- bootstrap of -flto=full -g). Except at some point it switched to using a CMake cache, and it has been using -gline-tables-only as well: http://lab.llvm.org:8080/green/job/clang-stage2-configure-Rlto_build/ http://lab.llvm.org:8080/green/job/clang-stage2-configure-Rlto_build/8599/consoleFull ) I hope the blowup is from the work I've done over the last couple of weeks; I'll continue investigating today and revert whatever I have to. Sorry for the noise and the breakage. (It's also poss...
