> crazy fast compilation times

This is just not true and it's the reason #1 I am not using Zig. To give you some numbers, ZLS is a reasonably sized project (around 62k LOC of Zig) and on my very beefy machine it takes 14 seconds to build in debug mode and 78 seconds to build in release mode.

Because of the "single compilation unit" approach that Zig uses this means you are paying for that very same time regardless of where you modify your program.. so basically clean rebuild time is equal to simple modification time.

As a comparison my >100k LOC game in Rust takes less than 10s to build in release mode for modifications that happen not too far down the crate hierarchy.

So yeah, be for whatever reason you want (LLVM, no incremental builds and so on) as for today Zig is not even close to having "crazy fast compilation times".

True, current compilation times with Zig are not yet optimal. We're getting there though. As our own custom backends become complete enough we will be able to enable incremental compilation and the aim is for instant rebuilds of arbitrarily large projects.

Since that post was written we completed the transition to self-hosted and the x86_64 backend is getting close to passing all behavior tests.
