In the loop vectorizer cost model, we used to ignore stores/loads of a pointer type when computing the widest type within a loop. This meant that if we had only stores/loads of pointers in a loop we would return a widest type of 8bits (instead of 32 or 64 bit) and therefore a vector factor that was too big. Now, if we see a consecutive store/load of pointers we use the size of a pointer (from data layout). This problem occured in SingleSource/Benchmarks/Shootout-C++/hash.cpp (reduced test case is the first test in vector_ptr_load_store.ll). radar://13139343 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174377 91177308-0d34-0410-b5e6-96231b3b80d8 |
