Currently clang diagnoses the following code: (https://godbolt.org/z/s8zK3E5P5) but nvcc does not. ` struct A { constexpr A(){} }; struct B { A a; int b; }; template<typename T> __global__ void kernel( ) { __shared__ B x; } ` Clang generates an implicit trivial ctor for struct B, which should be allowed for initializing a shared variable. However, the body of the ctor is defined only if the template kernel is instantiated. Clang checks the initialization of variable in non-instantiated templates, where it cannot find the body of the ctor, therefore diagnoses it. This patch skips the check for non-instantiated templates.
