If x32 marked as broken it does not hurt to the selftests as-is, right? I think sigreturn.c can stay as-is except for the comment referring to x32. syscall_numbering.c has plenty of x32 bits and I would go and remove them once start removing the x32 bits. The reason for 1/2 in this series is that the nolibc selftests expect x32 to be working on x86-64. But this isn't the case here afaik. Now that I test it run into https://lore.kernel.org/all/20261022142425.3Wx-RrU5@linutronix.de/ so the test is currently broken. Did I understand you properly? > thanks, > -- Shuah Sebastian
