Cosmic Software Frequently Asked Questions
How can I use the MAC instructions from C?
you first need to include the mac header file:
#include <mac.h>.
which predefines the variable mac.
After that, when you assign something to the variable "mac", the compiler will generate MAC instructions when possible:
mac += *p1++ * *p2++;
will generate
mov r1,[r12+] comac r1,[r13+]
