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 20:01:28 +02:00			`; RUN: opt < %s -ipconstprop -S \| grep {ret i32 %r}`
Fix PR2411, where ip constant prop would propagate the result of a weak function. llvm-svn: 52137 2008-06-09 09:58:07 +02:00			`; Should not propagate the result of a weak function.`
