Spread FUD? Ard literally sent TO YOU:
https://lore.kernel.org/lkml/CAMj1kXHxX+u5-cN0v3SLdqZTSiKsWsFOvc2SC5=-Sca...,
and it was referenced again in
https://lore.kernel.org/lkml/20201028081123.GT2628@hirez.programming.kick....
Was it FUD when Ard sent it to you? Did you even read the link you
dropped from my reply, which is what Ard quoted?
https://gcc.gnu.org/wiki/FAQ#optimize_attribute_broken
If it wasn't FUD when Ard sent it, why is it suddenly when I do?
