tests: Drop -polly-detect-unprofitable and -polly-no-early-exit 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 incorrectly set the inverted flag. In TempScopInfo::buildCondition we extract the conditions to guard the BB *in addition of* loop bounds. This means we should only consider the conditions in the paths (in CFG) that do not contain cycles (loops). At the same time, we set the invert flag if the FalseBB of the current branch dominates our target BB to indicate that we reach the target BB with an inverted condition from the current branch. In this case, the path from the FalseBB contains a cycle if the FalseBB is the target of a backedge. The conditions implied by such a path should not be consider. We can identify such a case by checking if the TrueBB also dominates our target BB, which means we can also reach our target BB from the TrueBB, without going through the backedge. llvm-svn: 222907

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
