--- Comment #13 from Andi Kleen <andi-gcc at firstfloor dot org> ---
+20%! from Jason's patch for the PR116285 test case.
I cannot test this one because the old avx512 headers don't work anymore.
But the patch looks like a winner.
../obj-fast/gcc/cc1plus-opt -O2 -mavx512f -std=gnu++20 -c
v8_base_without_compiler.runtime-temporal.ii ran
1.21 ± 0.02 times faster than ../obj-fast/gcc/cc1plus -O2 -mavx512f
-std=gnu++20 -c v8_base_without_compiler.runtime-temporal.ii
