[Llvm-bgq-discuss] Regression when linking with -fopenmp

[Schlottke-Lakemper, Michael]

Hi Hal, 

Did a quick check (compilation & linking but no execution) and I can confirm that the regression seems to be fixed now. Again, thanks for the fast response!

Hi Hal,

Thanks a lot for the quick fix. Since I am on vacation starting tomorrow, it might take me a while to confirm that it works.

Hi Michael,

You should find this fixed starting with tomorrow's nightly builds.
