Jingyue Wu	87a2b36cf6	[NVPTX] Make the alignment an explicit argument to ldu/ldg ... 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	2014-08-29 15:30:20 +00:00
Justin Holewinski	cb8f98382b	[NVPTX] Fix handling of ldg/ldu intrinsics. ... The address space of the pointer must be global (1) for these intrinsics. There must also be alignment metadata attached to the intrinsic calls, e.g. %val = tail call i32 @llvm.nvvm.ldu.i.global.i32.p1i32(i32 addrspace(1)* %ptr), !align !0 !0 = metadata !{i32 4} git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211939 91177308-0d34-0410-b5e6-96231b3b80d8	2014-06-27 18:35:51 +00:00
