Andi Kleen <andi-gcc at firstfloor dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |andi-gcc at firstfloor dot org --- 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
