Summary: We no longer add vectors of pointers as candidates for load/store vectorization. It does not seem to work anyway, but without this patch we can end up in asserts when trying to create casts between an integer type and the pointer of vectors type. The test case I've added used to assert like this when trying to cast between i64 and <2 x i16*>: opt: ../lib/IR/Instructions.cpp:2565: Assertion `castIsValid(op, S, Ty) && "Invalid cast!"' failed. #0 PrintStackTraceSignalHandler(void*) #1 SignalHandler(int) #2 __restore_rt #3 __GI_raise #4 __GI_abort #5 __GI___assert_fail #6 llvm::CastInst::Create(llvm::Instruction::CastOps, llvm::Value*, llvm::Type*, llvm::Twine const&, llvm::Instruction*) #7 llvm::IRBuilder<llvm::ConstantFolder, llvm::IRBuilderDefaultInserter>::CreateBitOrPointerCast(llvm::Value*, llvm::Type*, llvm::Twine const&) #8 Vectorizer::vectorizeStoreChain(llvm::ArrayRef<llvm::Instruction*>, llvm::SmallPtrSet<llvm::Instruction*, 16u>*) Reviewers: arsenm Reviewed By: arsenm Subscribers: nhaehnle, llvm-commits Differential Revision: https://reviews.llvm.org/D39296 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@316665 91177308-0d34-0410-b5e6-96231b3b80d8
