Thanks for your post.
This is indeed a confirmed issue with CodeXL 1.3. AMD will provide a fix for that in the upcoming releases.
Meanwhile to overcome this issue, you will need to delete the project and add the cl file again so it will take the new settings in the next compilation.
And another possible issue.
Statistics for Loveland shows 32 as wavefront size. If I recalled right I reported that issue before, with prev. profiler, and got answer that wave size in Loveland 64.
So, again, what wavefront size for Lovelang GPU ?
Thanks again for your post.
My search confirmed that indeed Loveland wavefront size is 64 for all sub-flavors. This is a possible issue in AMD Driver and should be fixed in upcoming releases.
