The goal is to remove all constants created during IR creation of a
function, once the function has been JITted. For example, after the
function has been JIIted, I can call llvm::Function->deleteBody, that
will delete the instructions in the function. But all llvm::Constants
created by the function will remain in memory. If I could attach a
LLVMContext per function to create the constants, I would be able to
delete all constants created for the function's body by deleting the
Does that make sense?
I know that this disables any IPO, but I'm currently more interested
into memory savings than optimizations.
