Dear Aneesh V,

But that's not what you are doing. You are not changing the storage of the global data itself, you are changing the storage of the POINTER TO the global data - and this makes no sense to me. The pointer can certainly remain in a register even if the data itself is somewhere else.
Why do we want to waste a register in the entire SPL when global data can be accessed directly from .data section?
Because the resulting code is smaller?
I was thinking that it may be faster. More number of registers at disposal may mean less number of pushes to the stack, right? I am not sure if this will make a significant difference.
