Hi,
compilation of the following program takes a very long time (> 1 minute):
__kernel void A() {
for (int g = 0; g < 100000; g++) {
barrier(1);
}
}
If optimizations are disabled (-cl-opt-disable
), compilation takes < 1 second.
This is on a GTX 1080 running driver 375.39 on Ubuntu Linux 16.04. On a GTX 780 with driver 361.42, compilation takes less than a second both with and without optimizations enabled.
Cheers,
Chris
