--- Comment #10 from Andi Kleen <andi-gcc at firstfloor dot org> ---
It doesn't really help for the PR119387 test case, perhaps not surprising
because it optimizes freeing not allocation:
Summary
./gcc/cc1plus-opt -w -std=c++20 ~/gcc/git/tsrc/119387-formatted.ii -quiet
ran
1.02 ± 0.03 times faster than ./gcc/cc1plus -w -std=c++20
~/gcc/git/tsrc/119387-formatted.ii -quiet
So still need a real test case.
