// AArch64 ABI actually requires the reverse of what this is testing: the callee
// does any extensions and remaining bits are unspecified.

// Win64 ABI does expect extensions for type smaller than 64bits.

// Technically this test wasn't written to test that feature, but it's a
// valuable check nevertheless.
