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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81537 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-11 18:01:28 +00:00			`; RUN: opt < %s -functionattrs -S \| not grep read`
Fix PR2792: treat volatile loads as writing memory somewhere. Treat stores as reading memory, just to play safe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56188 91177308-0d34-0410-b5e6-96231b3b80d8 2008-09-13 12:45:50 +00:00			`; PR2792`

Upgrade syntax of tests using volatile instructions to use 'load volatile' instead of 'volatile load', which is archaic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145171 91177308-0d34-0410-b5e6-96231b3b80d8 2011-11-27 06:54:59 +00:00			`%t = load volatile i32* @g ; <i32> [#uses=1]`
