Re: [hatari-devel] Code execution discontinuities and detecting them?

Hi Eero,

1. Yes. Until there's no stack overflow, it's possible in 'long interrupt' mode.

2. RTI will return where the 'long interrupt' occurs.

Moreover be carefull, there's a 'fast interrupt' mode: when the first word in the vector table is a JSR, the interrupt is a 'fast' one. The end of interrupt is done by a RTS and this kind of interrupts are not interruptible.

Hope this help, regards,

Didier

1. Can there be another exception while current one is being handled?

2. Will RTI return to previous exception previous handler, if it had
   not finished (instead of e.g. terminating all exceptions being handled
   at the moment)?
