Dan Gohman a334aa7a10 Teach ScalarEvolution how to analyze loops with multiple exit ... blocks, and also exit blocks with multiple conditions (combined with (bitwise) ands and ors). It's often infeasible to compute an exact trip count in such cases, but a useful upper bound can often be found. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73866 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-22 00:31:57 +00:00
