Owen Anderson 36c4debc94 Fix PR8247: JumpThreading can cause a block to become unreachable while still having predecessor, if it is part of a self-loop. ... Because of this, we cannot use the Simplify* APIs, as they can assert-fail on unreachable code. Since it's not easy to determine if a given threading will cause a block to become unreachable, simply defer simplifying simplification to later InstCombine and/or DCE passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115082 91177308-0d34-0410-b5e6-96231b3b80d8		2010-09-29 20:34:41 +00:00
