To make use of the vector built-in functions, builtins.h must
be included.
Note: The vector built-in functions are only visible when
vector support is enabled. In addition,
the vector built-in functions with
vector bool long long,
vector
signed long long, or
vector unsigned long long require
the LANGLVL(LONGLONG) compiler option in effect to be visible, and
the vector built-in functions with
vector double require
the FLOAT(IEEE) compiler option in effect to be visible.
