/* PR target/104694 involved GCC generating vextsd2q to convent long long to
__int128_t when the long long value was in the GPR register. This test
verifies that if the result is in the Altivec registers, we still want to
generate vextsd2q. We use __int128_t to indicate that we want the result of
the conversion to be in an Altivec register. */
