RNSBG is handled via the op_rosbg() helper function. But RNSBG has
the opcode 0xEC54, i.e. 0x54 as second byte, while op_rosbg() currently
checks for 0x55. This seems to be a typo, fix it to use 0x54 instead,
so that op_rosbg() does not abort() anymore if a program uses RNSBG.
I've checked with a simple test function that I now get the same results
with KVM and with TCG:
static void test_rnsbg(void)
{
uint64_t r1, r2;
r2 = 0xffff000000000000UL;
r1 = 0x123456789bdfaaaaUL;
asm volatile (" rnsbg %0,%1,12,61,16 " : "+r"(r1) : "r"(r2));
printf("r1 afterwards: 0x%lx\n", r1);
}
