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
Chris Lattner	6af608b8ce	Fix folding of icmp's of i1 where the comparison is signed. The code ... was using the algorithm for folding unsigned comparisons which is completely wrong. This has been broken since the signless types change. llvm-svn: 53444	2008-07-11 04:20:58 +00:00
Chris Lattner	4fa8bb3430	Fix a bogus optimization: folding (slt (zext i1 A to i32), 1) -> (slt i1 A, true) ... This cause a regression in InstCombine/JavaCompare, which was doing the right thing on accident. To handle the missed case, generalize the comparisons based on masked bits a little bit to handle comparisons against the max value. For example, we can now xform (slt i32 (and X, 4), 4) -> (setne i32 (and X, 4), 4) llvm-svn: 53443	2008-07-11 04:09:09 +00:00
