* Drop explicit -polly-delinearize parameterTobias Grosser2016-03-231-1/+1
| | | | | | | Delinearization is now enabled by default and does not need to explicitly need to be enabled in our tests. llvm-svn: 264154
* 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
* Do not detect Scops with only one loop.Tobias Grosser2015-08-271-1/+2
| | | | | | | | | | | | | | | | | | | | If a region does not have more than one loop, we do not identify it as a Scop in ScopDetection. The main optimizations Polly is currently performing (tiling, preparation for outer-loop vectorization and loop fusion) are unlikely to have a positive impact on individual loops. In some cases, Polly's run-time alias checks or conditional hoisting may still have a positive impact, but those are mostly enabling transformations which LLVM already performs for individual loops. As we do not focus on individual loops, we leave them untouched to not introduce compile time regressions and execution time noise. This results in good compile time reduction (oourafft: -73.99%, smg2000: -56.25%).

* 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
* Remove target triples from test casesTobias Grosser2015-04-211-1/+0
| | | | | | | | I just learned that target triples prevent test cases to be run on other architectures. Polly test cases are until now sufficiently target independent to not require any target triples. Hence, we drop them. llvm-svn: 235384
* Add sign-extension during codegen of index expressionsTobias Grosser2015-03-081-0/+25
When code generating array index expressions the types of the different components of the index expressions may not always match. We extend the type of the index expression (if possible) and assert otherwise. llvm-svn: 231592
