Hello everyone,
I would need to use some trap instructions to stop execution following certain conditions. From the SPARC models it would seen that traps from 0X80 eu 0xFF are free to use.
My question is : are some of those traps alreday used by eCos? I would like to keep my code eCos-compatible!
Thanks anyone,
Michele

Avoid traps 0x80 - 0x83 since they are used for breakpoints
and system calls in the SPARC ABI.
