Earlier creation of ScopStmt objects This moves the construction of ScopStmt to the beginning of the ScopInfo pass. The late creation was a result of the earlier separation of ScopInfo and TempScopInfo. This will avoid introducing more ScopStmt-like maps in future commits. The AccFuncMap will also be removed in some future commit. DomainMap might also be included into ScopStmt. The order in which ScopStmt are created changes and initially creates empty statements that are removed in a simplification. Differential Revision: http://reviews.llvm.org/D13341 llvm-svn: 249132

Allow switch instructions in SCoPs This patch allows switch instructions with affine conditions in the SCoP. Also switch instructions in non-affine subregions are allowed. Both did not require much changes to the code, though there was some refactoring needed to integrate them without code duplication. In the llvm-test suite the number of profitable SCoPs increased from 135 to 139 but more importantly we can handle more benchmarks and user inputs without preprocessing.

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
