The AltiVec built-in functions described in this section are available on the PowerPC family of processors starting with ISA 2.06 or later. These are normally enabled by adding `
-mvsx
`
to the command line.

When `
-mvsx
`
is used, the following additional vector types are implemented.

vector unsigned __int128 vector signed __int128 vector unsigned long long int vector signed long long int vector double

The long long types are only implemented for 64-bit code generation.
