* 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
* 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
* Drop -polly-vectorizer-unroll-only optionTobias Grosser2015-03-231-1/+0
| | | | | | | | This options was earlier used for experiments with the vectorizer, but to my knowledge is not really used anymore. If anybody needs this, we can always reintroduce this feature. llvm-svn: 232934
* Drop option to prepare code for the BB vectorizerTobias Grosser2015-03-121-1/+1
| | | | | | | | The BB vectorizer is deprecated and there is no point in generating code for it any more. This option was introduced when there was not yet any loop vectorizer in sight. Now being matured, Polly should target the loop vectorizer. llvm-svn: 232099
* 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 Grosser2015-02-191-2/+2
| | | | | | | | | | 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
* [isl-codegen]: Fix off by one in getNumberOfIterationsTobias Grosser2013-02-111-0/+29
We need to remove one dimension. Any is correct as long as it exists. We have choosen for whatever reason the dimension #dims - 2. This is incorrect if there is just one dimension. For CLooG this case did never happen. For isl however, the case can happen and causes undefined behavior including crashes. We choose now always the last dimension #dims - 1. We could have choosen dimension '0' but the last dimension is what we remove conceptionally in the algorithm, so it seems better to actually program it that way. While at it remove another piece of undefined behavior. llvm-svn: 174894
