@subsection SPARC VIS Built-in Functions
GCC supports SIMD operations on the SPARC using both the generic vector
extentions (@pxref{Vector Extensions}) as well as built-in functions for
the SPARC Visual Instruction Set (VIS). When you use the @option{-mvis}
switch, the VIS extension is exposed as the following built-in functions:

typedef short v4hi __attribute__ ((vector_size (8)));
typedef short v2hi __attribute__ ((vector_size (4)));
typedef char v8qi __attribute__ ((vector_size (8)));
typedef char v4qi __attribute__ ((vector_size (4)));
