--- Comment #12 from Andi Kleen <andi-gcc at firstfloor dot org> --- Okay. I only compared gcc-7 (working) vs gcc-9 (broken), but always with LTO. Looking at the kernel link it also uses --whole-archive. Perhaps that makes a difference? I'll redo the test case with --whole-archive (will need some fixes)
