[LLVMdev] How to handle size_t in front ends?
...lue is not known until code generation time or at least
until the compilation target is fully known. These "late bound
constants" could then be used to implement "sizeof(type)" and other
constants whose value is different on different targets.
On the C++ side, you would have ConstantSize(Type) which would be usable
anywhere that you could use ConstantInt, except that you can't actually
inspect the integer value of the constant or use it in expressions. That
part is fairly simple; It gets more complicated if you want to try
defining operators such as sizeof(A) + sizeof(B); T...

I really don't know how to do this. The current debug info stuff depends
on emitting size info into the IR. At this point, I don't

On a related topic: The source-level debugging descriptors require you
to know up front what the sizeof pointer types are. Is there any hope of
the frontend remaining blissfully unaware of platform details?
