Owen Anderson f8e3a19510 Teach LoopUnswitch not to perform non-trivial unswitching on loops containing convergent operations. ... Doing so could cause the post-unswitching convergent ops to be control-dependent on the unswitch condition where they were not before. This check could be refined to allow unswitching where the convergent operation was already control-dependent on the unswitch condition. llvm-svn: 249874		2015-10-09 18:40:20 +00:00
