I have somewhere in the code the following line:
int dist=sqrt(dx*dx+dy*dy);
I also heard that it's not a good idea to do 32 bit multiplies , so I
changed the types of dx and dy to short ... ( I use 4 bytes integers). When
I disassemble the debug code, I see that "muls" instructions are generated
(correct), but when I compile it into release and disassemble it again, the
generated instructions are "jsr __lmul__", which eat many more cycles,
as I understood. How can I correct this ?
Thanks,
Dan Patrutiu
