Usually the compiler will probably not generate those

you're betting against the compiler ever improving.

This would be a regression

Why? Automatic vectorization is pretty bad and has been for years, but wouldn't it be nice if the compiler could unroll-loops and use SIMD instructions to make your code faster while also being correct?

[saagarjha]

If you are using SIMD instructions on x86 you probably want the unaligned ones
