It's a bug in arch-test -- one I don't quite understand: even if newer compilers could have dropped the use of SWP, I can't seem to reproduce this failure even on jessie. A Pine64 with CONFIG_ARMV8_DEPRECATED=n on kernel 5.0-rc6, yet any jessie programs other than ghc work -- I remember anything with thread support crashing immediately. No idea what could have changed. I've dropped the check (both for SIGILL and for whether SWP gets silently ignored) -- worst case, there'll be false positives where debootstrap installs something that doesn't work. In general, I don't think debootstrap should work around bugs elsewhere; the design principle for arch-test is to err on the false positive rather than false negative side, thus setups that fail the test should be nearly useless. For the record, here's the list of checks above basic syscall test: * armhf: dmb (ARMv7) * i386: cmovz (686) * powerpc: fsel (!SPE) * powerpcspe: efscfsi (SPE) * ppc64el: mtvsrd (POWER8) Meow! -- ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ ⢿⡄⠘⠷⠚⠋⠀ Have you accepted Khorne as your lord and saviour? ⠈⠳⣄⠀⠀⠀⠀
