           Summary: Attempting uitofp from integer constant to fp128
                    causes assertion failure in APFloat.cpp:120
           Product: libraries
           Version: 2.8
          Platform: PC
        OS/Version: Linux
            Status: NEW

          Priority: P
         Component: Core LLVM classes

When I construct a ConstantInt (though I'm actually using the C bindings) using
the LLVM 2.8 release libraries and then proceed to construct a UIToFP cast
using LLVMBuildUIToFP(builder,value,FP128Ty,"cast").  This results in receiving
the following failed assertion:

/usr/src/llvm-2.8/lib/Support/APFloat.cpp:120: void assertArithmeticOK(const
llvm::fltSemantics&): Assertion `semantics.arithmeticOK && "Compile-time
arithmetic does not support these semantics"' failed.
