For hackers... a piece of test-code that does the same thing without
using the two jumps.
#include <stdio.h>
void delay(unsigned long loops)
{
__asm__ __volatile__(
"\tpushl %%cs\n"
"\tpushl $doit\n"
"\t.byte 0xcb\n"
".align 16\n"
"doit:\tdecl %0\n\tjns doit"
:/* no outputs */
:"a" (loops)
:"ax");
}
main()
{
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
delay(0xffffffff);
return 0;
}
