Dwarf2 has the idea of a location expression. It lets GCC specify
something like:

Reg %eax piece 4, Reg %ecx, piece 4

This is what is behind the dwarf2expr* et.al. changes. I'd download a
copy of the dwarf2 spec (see .../gdb/links/ but note that, right now the
m/c might be down - I got an e-mail last night indicating a temp outage).
