That's a very nice feature, it will save a lot of head-scratching.


Usage of ram, and register variables would be interesting.
IE who mucks with Thingy_pointer or  Other_thingy appears unused..

Possibly spotting variables in the upper register bank that could be moved 
to lower, or moved to ram with minimal impact..
Code segs that could be profitably made into subroutines.

I wrote one application where I deliberately overlapped my input buffer, 
output buffer, and stack space in SRAM, but with careful design, it was fine.
