Herald added a project: clang.

Added the option -vector-abi-compat=[default,gcc,xl]. The default behavior for
clang is for all vector compares to return a scalar unless the vectors being
compared are vector bool or vector pixel. In that case the compare returns a
vector. With the gcc case all vector compares return vectors and in the xl case
all vector compares return scalars.

This patch does not change the default behavior of clang.
