if I enable AVX instructions in code gen will the code just not run on CPUs without them or will they just use something else and be slower in that case?

I was actually wondering for the context of meow hash (since honestly, msvc with avx code gen enabled seems to do a whole lot of nothing for me vs just sse2) which uses intrinsics, so making an exe that can use both is like, half of the problem here
-
the other half being, I guess, use a different hash library if avx is disabled, which adds a bunch of maintenance overhead (nevermind that for hash functions specifically I'd probably have to encode 2 hash values into the data instead of 1 if I did that)
