Body
I'm toying around with the LLVM C++ API. I'd like to JIT compile code and run it. However, I need to call a C++ method from said JIT-compiled code. Normally, LLVM treats method calls as function calls with the object pointer passed as the first argument, so calling shouldn't be a problem. The real problem is to get that function into LLVM. As far as I can see, it's possible to use external linkage for functions and get it by its name. Problem is, since it's a C++ method, its name is going to be mangled, so I don't think it's a good idea to go that way. Making the <code>FunctionType</code> object is easy enough. But from there, how can I inform LLVM of my method and get a <code>Function</code> object for it?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
