            Bug ID: 26482
           Summary: CUDA support for __global__ lambdas
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: justin.lebar at gmail.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

The following code should compile (and generate a kernel lambda we can invoke).

void foo() {
  auto x = []()__global__ { };
}

Instead it gives the following error:

test.cu:2:15: error: kernel function type '<dependent type> () const' must have
void return type
  auto x = [] () __global__ { };
