I'm unable to produce any ISA with the KernelAnalyzer that has ds_
instructions in them.
Even when using the local id, like this:
__kernel void sample(
__global uint *input,
__local uint *buf,
__global uint *output) {
int gid = get_global_id(0);
int lid = get_local_id(0);
output[gid + lid] = input[gid] + input[gid + lid];
}

Daniel
