Dan Gohman	205b641954	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	2009-09-11 18:01:28 +00:00
Dan Gohman	8d84372836	Change these tests to feed the assembly files to opt directly, instead ... of using llvm-as, now that opt supports this. llvm-svn: 81226	2009-09-08 16:50:01 +00:00
Dan Gohman	db7860aa40	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. llvm-svn: 73866	2009-06-22 00:31:57 +00:00
