Is it possible to disable NEON to cause a trap with NEON code?

Hi Everyone, I'm trying to setup a test case on ARM A-32. I want to ensure a NEON code path is properly guarded at runtime. I'd like to disable NEON at boot time so that a SIGILL is raised for NEON instructions. If I get a SIGILL, it tells me there's some NEON in non-guarded paths. Is it possible to disable NEON at boot time? Thanks in advance. Jeff
