--- Comment #3 from Marius Messerschmidt <marius.messerschmidt at googlemail dot com> --- Sorry but I do not fully understand what you mean. Do you suggest using different command line arguments? So far I tried: -fdump-tree-all -fdump-tree-unswitch and -fopt-info-all-optall But none of them told me the all the things that I would wish to know, most important the reason why a particular loop was skipped during unswitching (e.g. because it is not invariant or so (right now it already reports a few things with -fdump-tree-unswitch like too-many-instructions or too-many-branches))
