...torizedLoopSkeleton(). “old scalar loop to handle remainder” is the one you want to vectorize again. Near the end of that function, LoopScalarBody is set. This is the loop body of interest. OrigLoop becomes the scalar Loop. First, try attaching a new metadata (with VF info) to it. 2) Create a RemainderVectorizePass, very similar to LoopVectorizePass, but let it work only on the loops that has the metadata. Add it to IPO/PassManagerBuilder right after LoopVectorize. You could also try adding a state in LoopVectorize instead of creating a RemainderVectorizePass. You can then read the metadata and try to vec...

Hi Hameeza, Aside from Ashutosh's patch..... When the vector width is that large, we can't keep vectorizing remainder like below. It'll be a huge code size if nothing else ---- hitting ITLB miss because of this is very bad, for example. VF=2048 // main vector loop VF=1024 // vectorized remainder 1 VF=512 // vectorized remainder 2 ... Vectorize remainder until trip count is
