For all RUN lines starting with "not", redirect stderr to /dev/null so tests don't fail when (expected) error output is produced. This fixes 17 tests. While I was there, I also made all RUN lines of the form "not llvm-as..." a bit more consistent, they now all redirect stderr and stdout to /dev/null and use input redirect to read their input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52174 91177308-0d34-0410-b5e6-96231b3b80d8 2008-06-10 12:57:32 +00:00			`; RUN: not llvm-as < %s >& /dev/null`
Fix for PR1633: Verifier doesn't fully verify GC intrinsics LLVM now enforces the following prototypes for the write barriers: <ty>* @llvm.gcread(<ty2>, <ty>) void @llvm.gcwrite(<ty>, <ty2>, <ty>*) And for @llvm.gcroot, the first stack slot is verified to be an alloca or a bitcast of an alloca. Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42051 91177308-0d34-0410-b5e6-96231b3b80d8 2007-09-17 20:30:04 +00:00			`; PR1633`
