Yes, but the testcase is invalid, because __builtin_ia32_movq128 should not be
used without SSE2. Fixed compiler reports:
pr94603.c: In function ‘foo’:
pr94603.c:6:10: warning: implicit declaration of function
‘__builtin_ia32_movq128’; did you mean ‘__builtin_ia32_movntps’?
[-Wimplicit-function-declaration]
pr94603.c:6:10: error: incompatible types when returning type ‘int’ but ‘V’
{aka ‘__vector(2) long long int’} was expected
