...se transformations, or re-using existing ones? If you're reusing existing ones, which ones? And how would they need to be modified to become 'OpenMP aware'? Can you please comment on the loop-analysis use case that I outline here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-October/054078.html Would this kind of simplification fall under the 'constant propagation' transformation, or will something else be required? What might be most useful is if we develop a set of optimization tests so that we have a set of use cases from which we can base a design. Do you already have a...
