------- Comment #1 from bonzini at gnu dot org 2006-12-14 17:23 -------
Builtin vmuloub has always returned "wrong" types, because it derives its types
simply from the modes of the altivec_vmuloub pattern. For this reason, the C
front-end uses vec_vmuloub instead: this one is expanded by
resolve_overloaded_builtin to add the appropriate casts on both the arguments
and the results.
The way to solve this bug could be to pass the two operands to
rs6000_builtin_mul_widen_even, and get back the fully-built tree, including
conversions to the appropriate return type.
