Dear Aneesh V,
In message 4DD24E63.3020006@ti.com you wrote:
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 did not measure it on your hardware with your compiler, but IIRC this was the result on some other processors.
Best regards,
Wolfgang Denk
