Why is the Rust compiler so slow?

Where is Cranelift mentioned

My 2c on this is nearly ditching rust for game development due to the compile times, in digging it turned out that LLVM is very slow regardless of opt level. Indeed it's what the Jai devs have been saying.

So Cranelift might be relevant for OP, I will shill it endlessly, took my game from 16 seconds to 4 seconds. Incredible work Cranelift team.

I think that’s what zig team is also doing to allow very fast build times: remove LLVM.
