--- Comment #9 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
FYI, pr113026-1.c has never passed on arm-eabi, at torture options "-O3
-fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions".
I've just tested at each commit associated with this PR. It fails in gcc-14
and trunk targeting gcc-15. The bogus warning is the same as in the initial
description:
