Re: [rtl] Simple floating point question

[Michael Barabanov <baraban@fsmlabs.com>]

Adam,

For doing this, I suggest using an FPU-enabled thread with a body like:

thread_code()
{
	while(1) {
		pthread_suspend_np(pthread_self());
		your_handler_work();
	}
}


interrupt_handler()
{
	pthread_wakeup_np(thread);
}

Also, I strongly suggest upgrading to 3.0pre8. Several important bugs have
been fixed since 2.0pre2.

Michael.
