--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I think this is just broken code.
It does:
#define HWY_BEFORE_NAMESPACE()
\
HWY_PUSH_ATTRIBUTES("altivec,vsx,power8-vector"
\
",cpu=power10")
But does not do a pop before the main function.
And then you are testing on power8 which obvious does not have all of the
instructions as power10 ...
Why it works without -flto is just pure accident not using the instructions
that are not in power8.
Anyways I suspect this is too much reduced testcase. So you might need to
provide the original one.
