DSNode Question

LLVM,

I am trying to equate two dsnodes across call boundries. On the Caller
side we have an operand of form:
sbyte * getelementptr ([20 x sbyte]* %.LC0, long 0, long 0)
using getNodeForValue() yields a NULL pointer.

On the Callee, the parameter is of form:
sbyte * S
and getNodeForValue works fine. Is there something special that must be
done to access DNodes accessed using GEP?

Thanks,
Dave

This wierd device is a "constantexpr": the object is actually a subclass
of Constant (because it evaluates to a link time constant), so I think the
node is getting elided. Vikram just checked in a fix that will probably
fix this, he can provide details...

I am not seeing this fix in the csil tree....
