[LLVMdev] Strange Errors

[Peter Finn]

I’m trying to debug DebugInstrumentation.cpp, and I got the following errors.  I don’t know what to make of them.  The constructor for DILocation requires 5 arguments, and I don’t know what I would use as the arguments if I were to correct this code.  Also, the type “DIDescriptor” apparently doesn’t exist: has it been renamed?  What’s going on?

Thanks,
Peter Finn
