Bug ID: 48671
Summary: c++2a constexpr destructors not supported for CUDA
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: CUDA
Assignee: unassignedclangbugs at nondot.org
Reporter: ryan_greenblatt at brown.edu
CC: llvm-bugs at lists.llvm.org
The following program builds under c++20 in c++ but not with CUDA:
```
struct A {
constexpr ~A() {
// some body is needed for the issue to occur
;
}
};
constexpr A a;
```
It fails to build with "error: dynamic initialization is not supported for
__device__, __constant__, and __shared__ variables."
I think the desired behavior would be for this to be valid CUDA.
