Summary: callee_saves pragma

Initial Comment:
I am using callee_saves pragma in my program in order to reduce its code size. SDCC manual says, on page 54, that extra code need to be manually inserted to save and restore registers, but examining the assembler code generated, I realized that the compiler generated push/pop instructions within the functions called. So now I am confused if I still need to manually insert any code or not.
