I'm trying to really understand PIC18 interrupts and have a question
(likely more to follow!).

Is there any performance benefit using the ASM goto statement in the
interrupt vector, like this:

void interrupt_at_high_vector(void)
{
	_asm GOTO high_isr _endasm
}

As opposed to just calling the function c-style, like this?:

void interrupt_at_high_vector(void)
{
	high_isr();
}

I've been using the goto version, which I think came from one of the
datasheets or programmer's manuals, but I'm curious whether there's
really any difference..

Thanks for your advice,

Nathan
