Struct melior::dialect::ods::memref::DmaWaitOperation

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

A dma_wait operation. Blocking DMA operation that waits for transfer completion.

DmaWaitOp blocks until the completion of a DMA operation associated with the tag element ‘%tag[%index]’. %tag is a memref, and %index has to be an index with the same restrictions as any load/store index. %num_elements is the number of elements associated with the DMA operation.

Example:

 dma_start %src[%i, %j], %dst[%k, %l], %num_elements, %tag[%index] :
   memref<2048 x f32>, affine_map<(d0) -> (d0)>, 0>,
   memref<256 x f32>, affine_map<(d0) -> (d0)>, 1>
   memref<1 x i32>, affine_map<(d0) -> (d0)>, 2>
 ...
 ...
 dma_wait %tag[%index], %num_elements : memref<1 x i32, affine_map<(d0) -> (d0)>, 2>
