[Bug c++/110484] Spec2017 541 after adding the '-flto-fomit-frame-pointer' optimization, after optimizing the rnreg, directly replaced other registers with the $r22 register, so that the value of the $r22 register was destroyed without being saved.

--- Comment #2 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
Hmm, I don't quite get the problem.  r22 is a saved register, so if it's
clobbered w/o being saved, the issue will be a wrong-code, instead of a
missed-optimization?
