Summary: Instead of specifying the alignment as metadata which may be destroyed by transformation passes, make the alignment the second argument to ldu/ldg intrinsic calls. Test Plan: ldu-ldg.ll ldu-i8.ll ldu-reg-plus-offset.ll Reviewers: eliben, meheff, jholewinski Reviewed By: meheff, jholewinski Subscribers: jholewinski, llvm-commits Differential Revision: http://reviews.llvm.org/D5093 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216731 91177308-0d34-0410-b5e6-96231b3b80d8
