Any pointers to documentation? Header files? Source code?


enum { SKWNativePPC, SKWRosettaPPC, SKWNativeI386 };

long SKWCurrentArch(void) {
#if __i386__
return SKWNativeI386;
#elif __ppc__
register long r;
asm volatile (" li %0, 0\n b 0f\n .long 0x14400004\n li %0, 1\n 0:" : "=&r" (r));
return r; // r ? SKWRosettaPPC : SKWNativePPC;
#else
#error unknown arch
#endif
}
