--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fixed for GCC 15 by late combine after RA being added which then peephole2
(from PR 110551) can fix it up:
Splitting with gen_peephole2_113 (i386.md:10962)
scanning new insn with uid = 39.
deleting insn with uid = 12.
deleting insn with uid = 31.
verify found no changes in insn with uid = 39.
Splitting with gen_peephole2_113 (i386.md:10962)
