[LLVMdev] How to Obtain a DataLayout Reference Given a Function & F

[Peter Finn]

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
