            Bug ID: 24731
           Summary: NVPTX: Invalid function names containing '.' are
                    emitted
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: PTX
          Assignee: unassignedbugs at nondot.org
          Reporter: tobias at grosser.es
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

The NVPTX backend happily generates code for the following IR:

define void @foo.bar() {
  ret void
}

However, the PTX code that contains a '.' is not accepted by the CUDA runtime
library linker. It would preferable if the NVPTX backend would verify the
function names and abort in case they are invalid in PTX assembly.
