             Bug #: 13354
           Summary: NVPTX intrinsics table misses __nvvm_* buitins
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org

patch

Although NVPTX implements almost all __nvvm_* intrinsics, Clang intrinsics
table for NVVM misses them all, what prevents frontend from recognizing these
intrinsics in the input source code, e.g. in nvvm/ci_include.h.

The attached patch adds the list of intrinsics. Some of them are commented out,
because backend does not implement them yet.
