Return values from functions are placed to the appropriate registers following a modified Microchip policy optimized for SDCC. The following table shows these registers:

size destination register
8 bits WREG
16 bits PRODL:WREG
24 bits PRODH:PRODL:WREG
32 bits FSR0L:PRODH:PRODL:WREG
>32 bits on stack, FSR0 points to the beginning
