Yes, looks like that is those are the scalar versions. I got them
mixed up with the vector definitions
vector unsigned long long int vec_pdep()
vector unsigned long long int vec_pext ()
vector unsigned long long int vec_cfuge ()
I was thinking the __builtin_name() was also referring to the vector
versions.
So, given that there are separate definitions, it does appear that the
names are all consistent with the documentation. Thanks Bill.
