I've addressed this in my follow-up response to this patch. Again, sorry for the mishap, I was overconfident when adjusting the patch just before sending. > Here, it would be nice to extend omp_max_vf in the host compiler, > such that if PTX offloading is enabled, and optimize && !optimize_debug > (and vectorizer on the host not disabled, otherwise it won't be cleaned up > on the host), it returns MIN (32, whatever it would return otherwise). Did you mean MAX (32, host_vf), not MIN? > How does this even compile? simt_lane is a local var in the if > (do_simt_transform) body. I addressed in this in the reposted patch too, a few hours after posting this broken code. > BTW, again, it would help if you post a simple *.ompexp dump on what exactly > you want to look it up. Sorry, I'm not following you here -- can you rephrase what I should post? Thanks. Alexander
