I see this sometimes; I suppose you want to "watch" the variable 'r'. 'r'
has temporary scope only, the compiler has no need to store it in  'home'
registers, therefore you cannot "watch" it.

I would get around this by inspecting the register contents after the
function returns by single stepping using the dissassembler view. Sometimes
however, I would store the local variable into a global.
