LLVM now violates the armhf baseline by using NEON, this can be reproduced as easy as: (sid_armhf-dchroot)bunk@abel:~$ llvm-config-7 Illegal instruction (sid_armhf-dchroot)bunk@abel:~$ gdb confirms that this is due to NEON usage. Additionally, this also causes FTBFS on some of our buildds: https://buildd.debian.org/status/fetch.php?pkg=rust-pulldown-cmark&arch=armhf&ver=0.2.0-1&stamp=1542734241&raw=0 https://buildd.debian.org/status/fetch.php?pkg=cargo&arch=armhf&ver=0.31.0-4&stamp=1542700136&raw=0 https://buildd.debian.org/status/fetch.php?pkg=mesa&arch=armhf&ver=18.2.5-2&stamp=1542760450&raw=0 It might even result in silently misbuilt packages, just imagine mesa would have disabled the feature instead of AC_MSG_ERROR. Note that these mentioned buildd problems are just the visible tip of the iceberg, the baseline violation is a problem that must be fixed even when the buildds change.
