// Test that there are no extraneous moves or fixups for SIMD bitselect
// operations.  See README-codegen.md for general information about this type of
// test case.

// The codegen enforces onTrue == output so we avoid a move to set that up.
//
// The remaining movdqa is currently unavoidable, it moves the control mask into a temp.
// The temp should be identical to the mask but the regalloc does not currently
// allow this constraint to be enforced.
