--- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I think the biggest issue now is:
```
;; _6 = _2 >= 0;
(insn 10 7 11 (set (reg:HI 48)
(not:HI (reg:HI 44 [ _2 ]))) "/app/example.cpp":6:3 -1
(nil))
(insn 11 10 12 (set (reg:HI 49)
(lshiftrt:HI (reg:HI 48)
(const_int 15 [0xf]))) "/app/example.cpp":6:3 -1
(nil))
(insn 12 11 0 (set (reg:QI 45 [ _6 ])
(subreg:QI (reg:HI 49) 0)) "/app/example.cpp":6:3 -1
(nil))
```
If this was expanded instead using the bit select.
I had noticed a similar thing in PR 109907 too.
