Hi Alexandre,

The bogus warning in pr113026-1.c is issued at some optimization

Regstrapped on x86_64-linux-gnu.  Also tested with aarch64-elf and
arm-eabi with gcc-15.  Ok to install?

I think this is not working as intended for gcc-16.

Since your change, I get this in my logs for Cortex-M0/3/4/7/33/55/85 and 
Cortex-A7:

On gcc-15, I do not get any message either, am I doing something wrong or how 
did you get the message?

Kind regards,
