Dan Gohman 40a5a1b39e Extend ScalarEvolution's multiple-exit support to compute exact ... trip counts in more cases. Generalize ScalarEvolution's isLoopGuardedByCond code to recognize And and Or conditions, splitting the code out into an isNecessaryCond helper function so that it can evaluate Ands and Ors recursively, and make SCEVExpander be much more aggressive about hoisting instructions out of loops. test/CodeGen/X86/pr3495.ll has an additional instruction now, but it appears to be due to an arbitrary register allocation difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74048 91177308-0d34-0410-b5e6-96231b3b80d8		2009-06-24 01:18:18 +00:00
