Author: emmettneyman Date: Thu Aug 9 14:59:01 2018 New Revision: 339392 URL: http://llvm.org/viewvc/llvm-project?rev=339392&view=rev Log: Added LLVM metadata to generated IR to increase vectorization width
Summary: Edited `loop_proto_to_llvm` to emit metadata at the end of the generated IR. This metadata will increase the vector width when the IR is optimized.
