When a loop gets bundled up, its outgoing edges are quite large, and can just barely overflow 64-bits. If one successor has multiple incoming edges -- and that successor is getting all the incoming mass -- combining just its edges can overflow. Handle that by saturating rather than asserting. This fixes PR21622. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223500 91177308-0d34-0410-b5e6-96231b3b80d8 |
