           Summary: Sparc lli fails on Regression/ExecutionEngine/test-cast
           Product: libraries
           Version: trunk
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Common Code Generator Code
        AssignedTo: sabre at nondot.org
        ReportedBy: criswell at uiuc.edu

The Sparc JIT fails from the following line in

cast float 0.0 to float

with the following assertion:

Assertion failed: mop.isImmediate(), file
line 170

It appears to be a bug in FixConstantOperandsForInstr()
(llvm/lib/CodeGen/InstrSelection/InstrSelectionSupport.cpp) where the function
does not handle the case where an operand is a constant from the constant pool.
