Michael Zolotukhin 4e7b10b07f Fix a trip-count overflow issue in LoopUnroll. ... Currently LoopUnroll generates a prologue loop before the main loop body to execute first N%UnrollFactor iterations. Also, this loop is used if trip-count can overflow - it's determined by a runtime check. However, we've been mistakenly optimizing this loop to a linear code for UnrollFactor = 2, not taking into account that it also serves as a safe version of the loop if its trip-count overflows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222451 91177308-0d34-0410-b5e6-96231b3b80d8		2014-11-20 20:19:55 +00:00
