Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537

Fix the expansion of umax and smax in the case where one or more of the operands have pointer type, so that the resulting type matches the original SCEV type, and so that unnecessary ptrtoints are avoided in common cases. llvm-svn: 75680

Teach ScalarEvolution how to compute a tripcount for a loop with true or false as its exit condition. These are usually eliminated by SimplifyCFG, but the may be left around during a pass which wishes to preserve the CFG. llvm-svn: 96683
