David Majnemer 3d90bb79c4 [LoopUnroll] Unroll loops which have exit blocks to EH pads ... We were overly cautious in our analysis of loops which have invokes which unwind to EH pads. The loop unroll transform is safe because it only clones blocks in the loop body, it does not try to split critical edges involving EH pads. Instead, move the necessary safety check to LoopUnswitch. N.B. The safety check for loop unswitch is covered by an existing test which fails without it. llvm-svn: 268357		2016-05-03 03:57:40 +00:00
