Unless your code targets some exotic architecture, like idk x86.

[cataphract]

Not really. Wait until the compiler starts vectorizing your code and using instructions requiring alignment (like the ones with A or NT in the mnemonic).

[saagarjha]

Usually the compiler will probably not generate those

> Usually...probably...

you're betting against the compiler ever improving.

[saagarjha]

This would be a regression

[bigfishrunning]

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
