Small temporary arrays in OpenCL

Question asked by realhet on Dec 7, 2012



Does OpenCL take advantage of the following techniques when using small local arrays?

- On VLIW -> indexed_temp_arrays (x0[n]) (aka. R55[A0.x] indirect register addressing in ISA)

- On GCN -> v_movrel_b32 instruction


Or if OpenCL always uses LDS memory for local arrays, is there an extension to enable those faster techniques?


Thanks in advance.
