But if you send me some inline asm, I'll patch it into busybox and
test a
2.6.34 initramfs for you.
Thanks! Try this:
void test_postinc(void)
{
double x = 0.0;
double a[2] = {3.5, 0.0};
double *p = a;
__asm__ volatile ("fneg.d (%0)+,%1" : "+a"(p), "+f"(x));
printf("postinc: result %f (expected %f), address %p
(expected %p)\n",
x, -3.5, p, a + 1);
}
void test_predec(void)
{
double x = 0.0;
double a[2] = {-1.75, 0.0};
double *p = a + 1;
__asm__ volatile ("fneg.d -(%0),%1" : "+a"(p), "+f"(x));
printf("predec: result %f (expected %f), address %p (expected
%p)\n",
x, 1.75, p, a);
}
