* 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
* Remove non-executed statements during SCoP simplifcationJohannes Doerfert2015-10-041-0/+47
A statement with an empty domain complicates the invariant load hoisting and does not help any subsequent analysis or transformation. In fact it might introduce parameter dimensions or increase the schedule dimensionality. To this end, we remove statements with an empty domain early in the SCoP simplification. llvm-svn: 249276
