The example in PR53315 is a runtime test case, except:
- it needs cpuid checks to be part of the test suite
- the printfs need to be replaced with asserts
- it needs to stop iceing first

Uros patch fixes it and the code is correct now. Please commit.
However in testing it I quickly hit PR53315

I am confused... is there anything wrong with current implementation or not?

Correction. We can keep the xor %reg,%reg. We just need it because setnz only
sets 8 bit to initialize the higher order bits.
Alternatively the value can be zero extended afterwards or

It is trivial, so posting right here:
#include
unsigned a;
int
rtm_xtest (void)
{
if (_xtest ())
a = 1;
}
