passing simple values by value, and structures by reference.  In
particular, I'd guess that it considers a one-element struct a simple
value.  Does that help?

"git clone" the existing XCB repos, and hack on the bits you want.  If
you want us to see some intermediate results, you can post a patch or
push the modified repo(s) somewhere we can see.  Note, though, as Peter
Harris said, that you should start from full clones of the existing

And yes, you absolutely want to focus on the code generation and not the
underlying code it generates.  You don't need to understand all the
details of the X protocol or specific protocol requests; you just need
to work out what the code generator generates for specific XML, where it
goes wrong (generating the wrong code), and how to fix it.

You have a large and complex code generator to work with, and the right
way to start figuring out the details you need to understand involves
doing experiments to see how it works.  Figuring out how to get started,
running the experiments, and understanding where to go from there will
take time.  Don't rush through it feeling like you've gotten behind
schedule.  As long as you keep working steadily on getting the general
idea of the code generation, understanding the effect of the bug you
want to fix (what code it generates versus what code it *should*
generate), and figuring out how to implement the padding rules I
mentioned in a previous email to you, you shouldn't have any trouble
getting done within the SoC timeframe.
