// We need to do a hack in inline assembly in some clang versions where we have
// to do `.intel_syntax noprefix`. This was fixed in clang in
// https://reviews.llvm.org/D113707, which made it into clang-14, but not in
// Apple's clang-14 that ships with Xcode 14.2. It was first fixed in Xcode 14.3
// where the clang version is 14.0.3.
