Dan Gohman	f2f6ce65b7	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-11 18:01:28 +00:00
Dan Gohman	3e054fe9ef	Use opt -S instead of piping bitcode output through llvm-dis. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81257 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-08 22:34:10 +00:00
Dan Gohman	b1e1e82c54	Change these tests to feed the assembly files to opt directly, instead ... of using llvm-as, now that opt supports this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81226 91177308-0d34-0410-b5e6-96231b3b80d8	2009-09-08 16:50:01 +00:00
Dan Gohman	efb9fbfdab	When forgetting SCEVs for loop PHIs, don't forget SCEVUnknown values. ... These values aren't analyzable, so they don't care if more information about the loop trip count can be had. Also, SCEVUnknown is used for a PHI while the PHI itself is being analyzed, so it needs to be left in the Scalars map. This fixes a variety of subtle issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71533 91177308-0d34-0410-b5e6-96231b3b80d8	2009-05-12 01:27:58 +00:00
