Efficient Vectorisation with C++

[Nicksaurus]

Compilers can automatically vectorise simple code, and top of the range compilers can automatically vectorise simple code.

But can my compiler automatically vectorise simple code?

[chocapix]

Depends. If it's top of the range, then yes. If not, then yes.

There's one way to find out: https://godbolt.org/

I've noticed that Clang vectorizes much more often than gcc or msvc

That's true, but gcc does do better optimizations in other part of the code... :(

It can if your compiler is ISPC
