18.10CE -Mllvm not supported on x86 Ubuntu 16.04?

Is LLVM code generation not supported by the Community Edition or did I miss something during the install or did i need to preinstall something?


Community edition is the same as the professional edition feature-wise. You should just need to specify -Mllvm to use its code generator.

This looks like a bug with the RC file, I’ve filed TPR#26484 to address it. In the meantime use pgfortran instead of pgf95. There shouldn’t be any semantic difference between pgf90/pgf95/pgfortran.

Thanks switching from pgf95 to pgfortran did the trick. After recompiling my engineering application, the execution time for one test case dropped from 49 to 31 seconds.
