Eliminate questionable syntax for stdin redirection. This probably also speeds things up a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51357 91177308-0d34-0410-b5e6-96231b3b80d8 2008-05-20 22:07:21 +00:00			`; RUN: llvm-as %s -o - \| opt -inline \| llvm-dis \| grep nounwind`

When inlining through an 'nounwind' call, mark inlined calls 'nounwind'. It is important for correct C++ exception handling that nounwind markings do not get lost, so this transformation is actually needed for correctness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45218 91177308-0d34-0410-b5e6-96231b3b80d8 2007-12-19 21:13:37 +00:00
