Look at the gyrations the Rust compiler team has been going through for years to be able to actually use LLVM's noalias (which is a very desirable optimization in Rust where the borrow checker statically guarantees absence of aliasing in a lot of code).

I haven't kept up with the current state of things, but if you can finally liberally use noalias in LLVM without having to fear miscompilations, you probably have solely the increased significance of Rust to thank for that.

We use gcc so honestly I'm not sure how the difference goes. I'm glad for Rust making the whole ecosystem more usable regardless.

GCC had to spend some time getting things correctly because of gfortran.
