Hal Finkel 9887ec31e6 Fix large count and negative constant count handling in PPCCTRLoops ... This commit fixes an assert that would occur on loops with large constant counts (like looping for ((uint32_t) -1) iterations on PPC64). The existing code did not handle counts that it computed to be negative (asserting instead), but these can be created with valid inputs. This bug was discovered by bugpoint while I was attempting to isolate a completely different problem. Also, in writing test cases for the negative-count problem, I discovered that the ori/lsi handling was broken (there was a typo which caused the logic that was supposed to detect these pairs and extract the iteration count to always fail). This has now also been corrected (and is covered by one of the new test cases). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177295 91177308-0d34-0410-b5e6-96231b3b80d8		2013-03-18 17:40:44 +00:00
