this arm code may JUST about fry your noodle lol

#define BKPT 0xde01

bool scan_for_breakpoints(void (*fun), int start, int depth)	/// scans a section of a function for break points
{
	int i;
	unsigned int inst;
	for(i=start-1;i<=depth;i+=2)	/// count from offset start to depth
	{
		inst = (*(volatile unsigned int *)((unsigned int)fun + i) & 0xffff);
		//printf("instruction: %x\r\n",inst);
		if (inst == BKPT)	/// if this is a break point
			return true;	/// return true
	}
	return false;
}
