How about this one:
---
extern void abort (void);
void
foo (int x)
{
if (x != 8)
abort ();
}
void
bar (int g)
{
register int x __asm__("ecx");
register int y __asm__("eax");
x = 5;
foo (1 << g);
asm ("mov %1, %0": "=r" (y): "r" (x));
Again still undefined because there is still inbetween the assignment
and the inline-asm.
if (x != 5)
abort ();
if (y != 5)
abort ();
}
int
main ()
{
bar (3);
return 0;
}
