Well, that's not necessarily true: different operating systems could
leave the ECR in different states after booting. That's why I asked.

Are you absolutely sure about this? I ask because gcc (at least the
version I'm using here) optimises this kind of stuff out completely
before the assembler even sees it. Look:
[tim@cyberelk tmp]$ cat out.c
void fn (void)
if (0) printf ("22");
[tim@cyberelk tmp]$ gcc -S out.c
[tim@cyberelk tmp]$ cat out.s
movl %esp, %ebp
subl $8, %esp
.ident "GCC: (GNU) 2.96 20000731 (Red Hat Linux 7.1 2.96-97.1)"
Do you have some example code that doesn't work as expected, to show
to the list?
