Hi Jakub! We have 3 pending patches with warnings/errors about omp pragmas:
1. https://gcc.gnu.org/ml/gcc-patches/2015-01/msg00617.html 2. https://gcc.gnu.org/ml/gcc-patches/2015-01/msg00621.html 3. This one. What should we do with them? [ ] Rebase and continue pinging. [ ] Postpone until Stage 1. [ ] Completely remove.
