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 -instcombine -S \| not grep sdiv`
Fix an icmp+sdiv optimization to check for and handle an overflow condition. This fixes PR2740. llvm-svn: 56076 2008-09-11 01:30:57 +02:00			`; PR2740`
