[LLVMdev] How to Obtain a DataLayout Reference Given a Function & F
I’ve been debugging SAFECode source code files, and line 170 in
ArrayBoundCheckLocal.cpp has been causing the following compilation error:

I assume I need to obtain a DataLayout reference from the argument of the
function “runOnFunction”. Is this correct? If so, how do I do this? If not,
what is supposed to be done instead?
Thanks,
Peter Finn

If not, what is supposed to be done instead?If you have a pointer to a Function object, you can get the Module in which the Function resides by calling the getParent() method of Function. If F is a pointer to an llvm::Function, then F->getParent() ... should return a pointer (or reference; I'm not sure which) to the Function's containing module. Once you have the Module, you can get the DataLayout.
