DAGCombiner could fold (truncate (load)) -> smaller load if the original load was the width of the truncation result or wider. This patch extends it to handle cases where the original load was narrower (and so the extension type stays the same). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197030 91177308-0d34-0410-b5e6-96231b3b80d8 |
