Chris,
How far do we want to go with conversion to APInt? Does this include GEP
indices too? For example, consider this code from
lib/Analysis/ConstantFolding.cpp
> if (isFoldableGEP) {
> uint64_t Offset = TD->getIndexedOffset(Ptr->getType(),
> (Value**)Ops+1, NumOps-1);
> Constant *C = ConstantInt::get(TD->getIntPtrType(), Offset);
> return ConstantExpr::getIntToPtr(C, ResultTy);
> }
The TargetData class could be altered to return an APInt value instead
of a uint64_t. This would then be used to construct the ConstantInt.
This would allow addressing beyond 64-bits but it seems like overkill to
me.
Your thoughts?
Reid.
