            Bug ID: 17327
           Summary: LLVM Tests fail on i386-pc-nto-qnx6.5.0 due to
                    non-standard expectations of UNIX commands
           Product: Test Suite
           Version: trunk
          Hardware: PC
                OS: other
            Status: NEW
          Severity: normal
          Priority: P
         Component: QMTest
          Assignee: unassignedbugs at nondot.org

    Classification: Unclassified

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/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)
