Hi,
How can I dedicate a register for special purpose, that means,
the dedicated register only appears in the inserted code of my own,
but never allocated in the rest of code. I have read some doc(gcc int)
about the register usage but still have no idea.
I would *really* appreciate any help I can get on this issue!
