--- Comment #4 from Fangrui Song <i at maskray dot me> --- Yes, the change will be straightforward, basically the files touched by the pending https://gcc.gnu.org/pipermail/gcc-patches/2022-July/597586.html ("[PATCH] Remove legacy -gz=zlib-gnu"). I sent it because I knew that we would need a new compression format, and some cleanup would make the logic more maintainable.
