Extended Description

QNX Neutrino 6.5.0 is a POSIX-compliant 32-bit operating system. I am porting LLVM to this system and have run into test failures that can be fixed with simple changes to the tests.

The following tests failed because they were using the non-standard ">& /dev/null" instead of "> /dev/null 2>&1": (See http://llvm.org/bugs/show_bug.cgi?id=9698)

test/Analysis/BasicAA/unreachable-block.ll test/Assembler/2003-11-11-ImplicitRename.ll test/Assembler/2007-11-26-AttributeOverload.ll test/CodeGen/X86/GC/badreadproto.ll test/CodeGen/X86/GC/badrootproto.ll test/CodeGen/X86/GC/badwriteproto.ll test/CodeGen/X86/GC/fat.ll test/CodeGen/X86/GC/outside.ll test/Other/2002-01-31-CallGraph.ll test/Transforms/GCOVProfiling/linkagename.ll test/Transforms/LoopStrengthReduce/pr2570.ll test/Verifier/2004-05-21-SwitchConstantMismatch.ll test/Verifier/2007-12-21-InvokeParamAttrs.ll test/Verifier/2008-01-11-VarargAttrs.ll test/Verifier/2009-05-29-InvokeResult1.ll test/Verifier/2009-05-29-InvokeResult2.ll test/Verifier/2009-05-29-InvokeResult3.ll test/Verifier/byval-1.ll test/Verifier/gcread-ptrptr.ll test/Verifier/gcroot-alloca.ll test/Verifier/gcroot-meta.ll test/Verifier/gcroot-ptrptr.ll test/Verifier/gcwrite-ptrptr.ll test/TableGen/UnterminatedComment.td

The following test uses grep "", instead of grep ".*" test/TableGen/lisp.td

The following test attempts to do a grep on a file without newlines. test/Transforms/GCOVProfiling/linkagename.ll (Note: for this test, it should echo the contents of the .gcno file to a temporary file (which will add the newline) and then grep the temporary file)

Please send a patch to llvm-commits.

Old build failure, tests are mostly not using grep anymore
