--- Comment #4 from Marcel Vollweiler <marcel at codesourcery dot com> --- Thanks Jakub! Although I checked for regressions, unfortunately I haven't seen this regression due to the dg-set-target-env-var topic. I assume that the icv-6.c test FAIL is caused by some other issue (your patch fixes the issue when multiple values are defind for OMP_PROC_BIND that is not the case in icv-6.c). So, I will have another look at icv-6.c ASAP.
