[LLVMdev] Access a specific address in the JIT compiler

[Olivier Meurant]

This seems to be the "proper" way to do that.

Another possibility, is to create a ConstantInt with the size of the pointer
(found in TargetData), then do a IntToPtr cast, and use this absolute
address in load/store/call.

Cheers,
Olivier.
