--- Comment #3 from Max S. <max.sagebaum at scicomp dot uni-kl.de> --- Ok, thanks for the hint with SRA. Know I know how to actually program it. I think the main problem is the warning/error message: > not vectorized: relevant phi not supported: matched_21 = PHI <_20(6), 1(5)> Is there some way to improve this?
