Some things are best optimized by the actual compiler.

gruez • Nov 3, 2018 • View on HN

you're greatly overestimating how much the compiler can optimize code.

g15jv2dp • Jun 22, 2024 • View on HN

Do you think other compilers for other languages don't perform optimizations like this?

temac • Jul 31, 2021 • View on HN

That's the case with tons of compiler optims.

Frankly if your compiler can't optimize this it's not worth using.

kroltan • Mar 29, 2021 • View on HN

Maybe "the compiler generates better assembly code per second than a human could"?

bluecalm • Nov 29, 2022 • View on HN

If you don't want the compiler to optimize that much then turn down the optimization level.

jhallenworld • Dec 3, 2018 • View on HN

I'm finding it impressive that the compilers even attempt to implement this optimization.

This should be abstracted away, optimizing for compiler performance feels straight out of the 80s.

Have you seen what optimizing compilers do? I'd hardly call that simple!
