--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So it looks like it is a bug in GCC 10.x and 11.x too and the only reason w=
hy
it was not caught back then was the testcase that was added was all 0 for t=
he
constant (gcc.target/aarch64/sve/pr94668.c).

Note -frounding-math testcases are a regression in GCC 12 though due to
r12-4767-g81342e95827f77c.

Note I am not going to do the backport of the patch, someone else can do th=
at.=
