Dan Gohman	1880092722	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	72a13d2476	Use opt -S instead of piping bitcode output through llvm-dis. ... llvm-svn: 81257	2009-09-08 22:34:10 +00:00
Dan Gohman	9737a63ed8	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	ae451600fa	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. llvm-svn: 71533	2009-05-12 01:27:58 +00:00
