control: severity -1 important
This is not baseline violation. julia -C
"armv7-a;armv7-a,neon;armv7-a,neon,vfp4"
compiles 3 branches of code, and the optimal branch will be selected
during runtime. The SIGILL raised during build on the buildd stems from
LLVM's incorrect CPU detection.
Here is a proof with QEMU emulated ARM Cortex-a7:
