[avr-gcc-list] Resetting the stack pointer

[John Butera]

<x-flowed>
In my INT0 interrupt handler, I use a large portion of the 512 bytes of 
sram available on the mega8515.

The interrupt handler disables all interrupts besides itself and 
eventually lets the watchdog reset the MCU, so anything on the stack 
before the interrupt is irrelevant.

Is it safe to simply do...
SP = RAMEND; /* Get sram back to a known state */
... to start with a new stack?

My INT0 handler has signal and noreturn attributes.  I am unsure if 
specifying naked would do anything different.  I have heard some talk 
about noreturn and naked on this list, but I'm not positive of the 
differences.  Any comments would be greatly appreciated.

Thanks,
John Butera
