Struct melior::dialect::ods::gpu::ShuffleOperation

pub struct ShuffleOperation<'c> { /* private fields */ }

A shuffle operation. Shuffles values within a subgroup..

The “shuffle” op moves values to a different invocation within the same subgroup.

Example:

%1, %2 = gpu.shuffle %0, %offset, %width xor : f32

For lane k returns the value from lane k ^ offset and true if that lane is smaller than %width. Otherwise it returns an unspecified value and false. A lane is the index of an invocation relative to its subgroup.

The width specifies the number of invocations that participate in the shuffle. The width needs to be the same for all invocations that participate in the shuffle. Exactly the first width invocations of a subgroup need to execute this op in convergence.
