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 2009-09-12 02:01:28 +08:00			`; RUN: opt < %s -instcombine -S \| not grep call`
calls in nothrow functions can be marked nothrow even if the callee is not known to be nothrow. This allows readnone/readonly functions to be deleted even if we don't know whether the callee can throw. llvm-svn: 71676 2009-05-14 01:39:14 +08:00			`; rdar://6880732`
