--- Comment #10 from Jens Seifert <jens.seifert at de dot ibm.com> --- Does this affect loop vectorize and slp vectorize ? -fno-tree-loop-vectorize avoids loop vectorization to be performed and workarounds this issue. Does the same problems also affect SLP vectorization, which does not take place in this sample. In other words, do I need -fno-tree-loop-vectorize or -fno-tree-vectorize to workaround this bug ?
