Der Code macht übrigens das hier:
#include <mint/osbind.h>
#include <setjmp.h>
jmp_buf env;
void access_fault_exception(void) __attribute__((interrupt));
void access_fault_exception(void)
{

longjmp(env, 0);
}
void illegal_exception(void) __attribute__((interrupt));
void illegal_exception(void)
{
Cconws("illegal instruction\r\n");
longjmp(env, 0);
}
void linef_exception(void) __attribute__((interrupt));
void linef_exception(void)
{
Cconws("linef exception\r\n");
longjmp(env, 0);
}
void coprocessor_protocol_exception(void) __attribute__((interrupt));
void coprocessor_protocol_exception(void)
{
Cconws("coprocessor protocol violation\r\n");
longjmp(env, 0);
}
void check_pmmu(void)
{
void *old_access, *old_illegal, *old_linef, *old_coproc;

old_illegal = Setexc(4, illegal_exception);

if (!setjmp(env))
{
__asm__ volatile(
" moveq #0,d0 \n\t"
" .long 0xf0390800 \n\t" // pmove 0,tt0
" .long 0x00000000 \n\t"
