// This test uses ignore-msvc, because the expected optimization does not happen on targets using
// SEH exceptions with the new LLVM pass manager anymore, see
// https://github.com/llvm/llvm-project/issues/51311. The core issue is that Rust promises that
// the drop_in_place() function can't unwind, but implements it in a way that *can*, because we
// currently go out of our way to allow longjmps, which also use the unwinding mechanism on MSVC
// targets. We should either forbid longjmps, or not assume nounwind, making this optimization
// incompatible with the current behavior of running cleanuppads on longjmp unwinding.
