* tests: Drop -polly-detect-unprofitable and -polly-no-early-exitTobias Grosser2015-10-061-1/+1
| | | | | | | | These flags are now always passed to all tests and need to be disabled if not needed. Disabling these flags, rather than passing them to almost all tests, significantly simplfies our RUN: lines. llvm-svn: 249422
* Rename IslCodeGeneration to CodeGenerationTobias Grosser2015-05-121-1/+1
| | | | | | | | | Besides class, function and file names, we also change the command line option from -polly-codegen-isl to just -polly-codegen. The isl postfix is a leftover from the times when we still had the CLooG based -polly-codegen. Today it is just redundant and we drop it. llvm-svn: 237099
* Update Polly tests to handle explicitly typed gep changes in LLVMDavid Blaikie2015-02-271-1/+1

* ScopDetection: Only detect scops that have at least one read and one writeTobias Grosser2015-02-191-1/+1
| | | | | | | | | | Scops that only read seem generally uninteresting and scops that only write are most likely initializations where there is also little to optimize. To not waste compile time we bail early. Differential Revision: http://reviews.llvm.org/D7735 llvm-svn: 229820
* Add early exits for SCoPs we did not optimizeJohannes Doerfert2015-02-111-1/+1
| | | | | | | | | | | | | This allows us to skip ast and code generation if we did not optimize a SCoP and will not generate parallel or alias annotations. The initial heuristic to exit is simple but allows improvements later on. All failing test cases have been modified to disable early exit, thus to keep their coverage.

* Remove -polly-codegen-scev option and related codeTobias Grosser2014-11-301-1/+1
| | | | | | | | SCEV based code generation has been the default for two weeks after having been tested for a long time. We now drop the support the non-scev-based code generation. llvm-svn: 222978
* Align copied load/store instructions as the original.Johannes Doerfert2014-10-021-0/+36
This also forbids the json importer to access other memory locations than the original instruction as we to reuse the alignment of the original load/store. Differential Revision: http://reviews.llvm.org/D5560 llvm-svn: 218883
