            Bug ID: 48933
           Summary: Find and fix more unsupported type uses in device code
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Clang Compiler Support

We diagnose a lot of expression uses of unsupported types but sme declarations
slip through. They still can cause the backend to crash. Two I found so far:


```
#pragma omp declare target
long double a() {
    return 0;
}

void c(long double a) { }
#pragma omp end declare target

```
