Chris Lattner	6e84f48cd8	Enhance a bunch of transformations in instcombine to start generating ... exact/nsw/nuw shifts and have instcombine infer them when it can prove that the relevant properties are true for a given shift without them. Also, a variety of refactoring to use the new patternmatch logic thrown in for good luck. I believe that this takes care of a bunch of related code quality issues attached to PR8862. llvm-svn: 125267	2011-02-10 05:36:31 +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
Reid Spencer	cdd728cca2	For PR1319: ... Make use of the END. facility on all files > 1K so that we aren't wasting CPU cycles searching for RUN: lines that we'll never find. llvm-svn: 36059	2007-04-15 07:38:21 +00:00
Reid Spencer	c49d7dd886	For PR1319: ... Upgrade tests to work with new llvm.exp version of llvm_runtest. llvm-svn: 36013	2007-04-14 20:13:02 +00:00
