Subject: [nvvm] Mark ldu and ldg intrinsics as IntrArgMemOnly.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e598f97f6c933b38107facfd7ad561b2ccf0a675;p=llvm

[nvvm] Mark ldu and ldg intrinsics as IntrArgMemOnly.

Summary:
Previously these intrinsics were marked as can-read any memory address.
Now they're marked as reading only the pointer they're passed.
