/* NON-TRADITIONAL BEHAVIOR HERE: Besides introducing the
__builtin_vec_ld and __builtin_vec_st built-in functions,
the VSX_BUILTIN_VEC_LD and VSX_BUILTIN_VEC_ST symbolic constants
introduced below are also affiliated with the __builtin_vec_vsx_ld

binding is formed with explicit calls to the def_builtin function
found in rs6000.c. */
