ScopInfo: Pass domain constraints through error blocks Previously, we just skipped error blocks during scop construction. With this change we make sure we can construct domains for error blocks such that these domains can be forwarded to subsequent basic blocks. This change ensures that basic blocks that post-dominate and are dominated by a basic block that branches to an error condition have the very same iteration domain as the branching basic block. Before, this change we would construct a domain that excludes all error conditions. Such domains could become _very_ complex and were undesirable to build. Another solution would have been to drop these constraints using a dominance/post-dominance check instead of modeling the error blocks. Such a solution could also work in case of unreachable statements or infinite loops in the scop. However, as we currently (to my believe incorrectly) model unreachable basic blocks in the post-dominance tree, such a solution is not yet feasible and requires first a change to LLVM's post-dominance tree construction. This commit addresses the most sever compile time issue reported in: http://llvm.org/PR25458 llvm-svn: 252713

Prepare unit tests for update to ISL 0.16 ISL 0.16 will change how sets are printed which breaks 117 unit tests that text-compare printed sets. This patch re-formats most of these unit tests using a script and small manual editing on top of that. When actually updating ISL, most work is done by just re-running the script to adapt to the changed output. Some tests that compare IR and tests with single CHECK-lines that can be easily updated manually are not included here. The re-format script will also be committed afterwards. The per-test formatter invocation command lines options will not be added in the near future because it is ad hoc and would overwrite the manual edits. Ideally it also shouldn't be required anymore because ISL's set printing has become more stable in 0.16. Differential Revision: http://reviews.llvm.org/D16095 llvm-svn: 257851

; CHECK: Assumed Context:
Track assumptions and restrictions separatly In order to speed up compile time and to avoid random timeouts we now separately track assumptions and restrictions. In this context assumptions describe parameter valuations we need and restrictions describe parameter valuations we do not allow. During AST generation we create a runtime check for both, whereas the one for the restrictions is negated before a conjunction is build. Except the In-Bounds assumptions we currently only track restrictions. Differential Revision: http://reviews.llvm.org/D17247 llvm-svn: 262328

; CHECK: Invalid Context:
Record assumptions first and add them later There are three reasons why we want to record assumptions first before we add them to the assumed/invalid context: 1) If the SCoP is not profitable or otherwise invalid without the assumed/invalid context we do not have to compute it. 2) Information about the context are gathered rather late in the SCoP construction (basically after we know all parameters), thus the user might see overly complicated assumptions to be taken while they would have been simplified later on. 3) Currently we cannot take assumptions at any point but have to wait, e.g., for the domain generation to finish. This makes wrapping assumptions much more complicated as they need to be and it will have a similar effect on "signed-unsigned" assumptions later. llvm-svn: 266068
