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 -functionattrs -S \| not grep read`
Fix PR3754: don't mark functions that wrap MallocInst with the readnone. Since MallocInst is scheduled for deletion it doesn't seem worth doing anything more subtle, such as having mayWriteToMemory return true for MallocInst. llvm-svn: 71077 2009-05-06 16:42:00 +08:00			`; PR3754`
