Illegal instruction core dump

[mingodad]

Hello !
I'm converting snabb to ljs (see https://github.com/mingodad/snabb-ljs and https://github.com/mingodad/ljs ) and now it pass all selftests the snabb luajit pass on my machine.
But it seems that there is some asm code using instructions for features not present on the cpu.

I've tested on Celeron (sse 4.1) and Atom (sse 3) cpus.

lib.ctable:Illegal instruction (core dumped)
lib.hash.siphash:selftest: .Illegal instruction (core dumped)
lib.ipsec.aes_128_gcm:Illegal instruction (core dumped)
