<pre>With the tip-of-tree Clang, this is failing to compile because the
-Winvalid-constexpr has gotten more strict after r360499
(<a href="https://github.com/llvm/llvm-project/commit/d05df0ef4362855405ae1df76572909fb0ff55b2">https://github.com/llvm/llvm-project/commit/d05df0ef4362855405ae1df76572909fb0ff55b2</a>):
usb-mass-storage.cpp:30:37: error: constexpr function never produces a
constant expression [-Winvalid-constexpr]
static constexpr usb_descriptor Create(usb_endpoint_descriptor_t
descriptor) {
^
usb-mass-storage.cpp:32:25: note: member call on member 'endpoint' of union
with active member 'interface' is not allowed in a constant expression
retval.endpoint = descriptor;
^
1 error generated.
It would be useful if the note also included the name of the member which is
being called (in this case it's operator= but that's not completely obvious
from the message).</pre>
