/* WG14 N1396: Partial
 * Wide function returns (alternate proposal)
 *
 * This only applies if attempting to conform to Annex F. Clang is not claiming
 * conformance to Annex F, but we do aim for conformance. This means that the
 * return statement converts the value to the return type of the function
 * rather than return the result in a wider evaluation format. We test this by
 * using a return statement without a cast and ensure it produces the same IR
 * as a return statement with an explicit cast.
 *
 * Clang conforms on targets other than 32-bit x86 (without SSE2), which is why
 * support is only partial. Once support for that target is dropped, Clang
 * should be conforming to this paper on all targets. See
 * https://github.com/llvm/llvm-project/issues/44218 and other linked issues
 * for further details.
