                parameter-transfer registers,return address registers and
stack/frame registers and other instruction specific and fixed-
function specific registers are handled by perpending and appending
move instructions to the register usages.
For caller/callee saved registers : A call instruction must cause all
volatile (caller-saves) registers to
interfere will all virtual register live at the call point.
Is there anything else other than this ?


Any help would be appreciated.
