Anyone was successful with setting up LTO/PGO with GCC?

Help

A couple of weeks ago I was trying to get LTO working with GCC and did not had much luck with that. Maybe someone already has a flake with it or has some resources to share on this topic?

I’ve been working on trying to get LTO working myself. However, I’ve been stuck on symbols missing in GNU hello & libgcc during linking. At one point, I even managed to crash the linker.

Ngl, I kinda expected to see more peeps interested in this topic

@RossComputerGuy can you share your flake here? Maybe I or somebody else will play around with it

I don’t have a Flake, it’s a PR that I’ve been working on. cc-wrapper: add lto support by RossComputerGuy · Pull Request #399656 · NixOS/nixpkgs · GitHub
