pub fn plane_ballot(_elem: bool) -> Line<u32>Expand description
Perform a ballot operation across all units in a plane.
Returns a set of 32-bit bitfields as a Line, with each element containing the value from 32
invocations.
Note that line size will always be set to 4 even for PLANE_DIM <= 64, because we can’t
retrieve the actual plane size at expand time. Use the runtimePLANE_DIM to index appropriately.
