...! Please, MLIR dev, let me know if this debug feature and the solution that Lang describes below is interesting for MLIR. I’ll dig more into the details then but it doesn’t seem too complicated.

Hi! I would appreciate some feedback from someone with experience in SCEV/SE. D39346 tries to fix an issue in LV (PR34965) that exposes a limitation in SCEV/SE. The best solution to the LV issue might not be a fix at SCEV/SE level but we may want to report/address SCEV/SE limitation as well. For the snippet below, LV expects SE to return a SCEVAddRecExpr for %21. However, SE returns ((4 * (zext

Hi, I noticed that the dead instructions collected when build vplan are invariant to different ranges of VFs since the original loop is not changed. Maybe DeadInstructions should be treated as a data member of LoopVectorizationPlanner and initialized by collectTriviallyDeadInstructions() in plan()?

Hi, Current loop vectorizer uses a range of vectorization factors computed by MaxVF. For each VF, it setups unform and scalar info before building VPlan and the final best VF selection. The best VF is also selected within the VF range. for (unsigned VF = 1; VF <= MaxVF; VF *= 2) { // Collect Uniform and Scalar instructions after vectorization with VF.

All, I'm trying to refactor LoopVectorize such that it has better conformance to VPlan vision going forward (http://www.llvm.org/docs/Proposals/VectorizationPlan.html). All VP*Recipe class definitions are now moved to VPlan.h, and I have a patch under review to move LoopVectorizationPlanner class out of LoopVectorize.cpp (https://reviews.llvm.org/D41420). Next thing I'm working on is

Hi, I found with the help of the optimization remarks a loop that could not be vectorized, but if loop distribution was enabled this may happen, which it in fact did with a very significant benchmark improvement (~25%). I tried (on SystemZ) to enable this pass, and found that it only affected a handful of files on SPEC. This means I could enable this without worrying about any regressions on

We are pleased to announce that John Chambers has joined the R core team. It is hard to believe that anyone on this list wouldn't know who John is, but just in case: He is the principal designer of the S language and environment, for which he received the ACM Software Systems Award in 1999. John has been very supportive and helpful throughout the development of R. He is joining the core
