Eli Friedman	b0e846a68c	PR9634: Don't unconditionally tell the AliasSetTracker that the PreheaderLoad ... is equivalent to any other relevant value; it isn't true in general. If it is equivalent, the LoopPromoter will tell the AST the equivalence. Also, delete the PreheaderLoad if it is unused. Chris, since you were the last one to make major changes here, can you check that this is sane? llvm-svn: 129049	2011-04-07 01:35:06 +00:00
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	c95df8b6d8	Use opt -S instead of piping bitcode output through llvm-dis. ... llvm-svn: 81257	2009-09-08 22:34:10 +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
Devang Patel	42f006a51a	Relax unsafe use check. If there is one unconditional use inside the loop then it is safe to promote value even if there is another conditional use inside the loop. ... llvm-svn: 42493	2007-10-01 18:12:58 +00:00
