One thing I had meant to say and forgot is that Tom reviewed patch #1,
and said 2 things: patch looks good, but we should be looking at
implementing the AX part for DW_OP_push_object_address now.

I would gladly do so, and will commit to having this done in a timely
manner, if someone was kind enough to give me a little bit of direction
on how to do this. I know Tom gave a reference to
dwarf2_compile_expr_to_ax, but I'm still clueless on how this is
supposed to be implemented. For instance, am I supposed to implement
this using a new operand, or can I translate that using already known
operands). Anyway, this can be implemented independently anyway,
so I'll do it as soon as I know how!

Thank you,
