Bug ID: 41634
Summary: [ppc] llvm.experimental.reduce.{and, any} don't lower
properly for boolean vectors
Product: libraries
Version: trunk

Status: NEW
Severity: enhancement

Split off from [Bug #36702], PPC fails to use the 'vec_all_*, vec_any_*'
intrinsic patterns for boolean reduction from generic IR - either with the
llvm.experimental.vector.reduce intrinsics (which expand to a shuffle reduction
chain) or with bitcasts of the comparison result mask:
