           Summary: many tests fail because Windows MKS doesn't understand
                    /dev/null or >& shell syntax
           Product: Test Suite
           Version: trunk
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P
         Component: lit
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: dneto.llvm at gmail.com

My config is:  Windows XP + MSVC 9 + Cmake + Nmake + MKS.

Many LLVM tests fail because they use /dev/null, because MKS doesn't understand
/dev/null.
The lit TCL test infrastructure doesn't rewrite the test script to eliminate
/dev/null.   Furthermore, the MKS setup doesn't understand the >& construct.

For example:  test/Assembler/2003-11-11-ImplicitRename.ll has this:
   ; RUN: not llvm-as < %s >& /dev/null
