...ss manager in PassManagerBuilder.cpp consecutively without any func/module pass in between, I used to think they would belong to the same loop pass manager. But it does not seem to be the case. For example for this code snippet PM.add(createIndVarSimplifyPass()); // Canonicalize indvars MPM.add(createLoopIdiomPass()); // Recognize idioms like memset. addExtensionsToPM(EP_LateLoopOptimizations, MPM); MPM.add(createLoopDeletionPass()); // Delete dead loops .. if (!DisableUnrollLoops) MPM.add(createSimpleLoopUnrollPass(OptLevel)); // Unroll small loops...

It seems it is necessary to run this pass after Polly code generation. Any pass order should yield correct code. If this is not the case there is either a bug in Polly or we expose a bug in LLVM. We should track this down. Our path ordering...

Andy and I briefly discussed this the other day, we have not yet got chance to list a detailed pass order for the pre- and post- IPO scalar optimizations. This is wish-list in our mind: pre-IPO: based on the ordering he propose, get rid of the inlining (or just inline tiny func), get rid of all loop xforms... post-IPO: get rid of inlining, or maybe we still need it, only

Hey guys, We had to recompile apache 2.4.12 because we needed to disable thread safety in php (ZTS). Because for some reason when compiling php with the --disable-maintainer-zts with the worker mpm model and checking the php info page, it was saying that thread safety was still enabled. So when we recompiled apache to use the prefetch worker model instead of worker, the php info page was showing that thread safety was disabled. But after that change apache processes spiked from around 11 p...
