The branch that skips irreducible backedges was only active when propagating mass at the top-level. In particular, when propagating mass through a loop recognized by `LoopInfo` with irreducible control flow inside, irreducible backedges would not be skipped. Not sure where that idea came from, but the result was that mass was lost until after loop exit. Added a testcase that covers this case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206860 91177308-0d34-0410-b5e6-96231b3b80d8 |
