Debugger already support 8, 16 & 32-bit variables, so that's not a problem.

I don't see why not. I just need a function that maps variable names to
their addresses & sizes and call that if name didn't match to a register.

First I'd like a bit more complete list of all the variables that you,
Thomas, Laurent etc would want to be available to the debugger though...
For the release this will support only global variables.

(Maybe later there could be also accessor functions for non-globals
variables that this function could use.  It doesn't make sense to make
globals from static variables just for the debugger.)
