In r304074 we introduce a patch to accept results from side effect free functions into SCEV modeling. This causes rejection of cases where the call is happening outside the SCoP. This patch checks if the call is outside the Region and treats the results as a parameter (SCEVType::PARAM) to the SCoP instead of returning SCEVType::INVALID. Patch by Sameer Abu Asal. llvm-svn: 305423
