Re: how to access PC

[Andrew Pinski <pinskia at physics dot uc dot edu>]

Try this function:
void * __attribute__((noinline)) getpc()
{
	void *t;
	asm("mflr %0":"=r"(t));
	return t;
}
It might not work always because of sibcalling optimizations but it 
should get you started.

Thanks,
Andrew Pinski
