<pre>$ cat method-target-mismatch.cu
struct S {
void method() {}
};
__attribute__((device)) void foo() {
S s;
s.method();
}
When compiled with nvcc:
$ /usr/local/cuda/bin/nvcc --verbose -I/usr/local/cuda/include -m64
--gpu-architecture=compute_35 -c method-target-mismatch.cu
...
method-target-mismatch.cu(7): error: calling a __host__ function("S::method")
from a __device__ function("foo") is not allowed
When compiled with Clang (trunk):
$ $LLVMSVN/clang -cc1 -x cuda method-target-mismatch.cu
$
No error generated.
Clang *does* generate an error when the mismatch is for a function (not
method), or a special method like default constructor.</pre>
