Infortunately I haven't found any API (JIT and codegen) where I can get from a MCSymbol to a DebugLoc. Does that interface exist? If not, I plan on committing  a small change in the GC code where the debug location is passed to the constructor of a GC point. Patch attached.

I do not know anything about GC support,  however labels do not have location info but you may be able to use location of  the first instruction after a label. Variables' debug info is handled separately.
