--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The difference between GCC 12 and GCC 13 is:
GCC 13:
```
IF-THEN-JOIN block found, pass 1, test 2, then 3, join 4
```
GCC 12 and before:
```
IF-THEN-ELSE-JOIN block found, pass 1, test 2, then 3, else 4, join 5
```
Someone will have to debug ifcvt.cc to see why it fails on x86_64 but works on
aarch64. Note there are some new changes to ifcvt.cc in review which might
improve this, though I am not sure.
