> Any plan to use this in rustc?
One of the primary expectations / use cases for cranelift is its use for rustc's debug builds: https://github.com/CraneStation/cranelift/blob/master/rustc....

What Hacker News says
6 sourcesIf you want a simple modern compiler backend intended for production-readiness, consider Cranelift [1]. It's largely written by Dan Gohman, who is a longtime LLVM contributor (and a colleague of mine). It does a lot of the things LLVM's backend passes do, but it's cleaner and better factored, with the benefit of a decade of hindsight [2]. Cranelift should be great for teaching purposes.

In GCC null pointer check removedLook at Cranelift [1], in particular "Cranelift compared to LLVM" [2]. Cranelift is in some ways an effort to rearchitect LLVM for faster compilation speed, written by some longtime LLVM contributors. For example, Cranelift has only one IR, which lets it avoid rebuilding trees over and over, and the IR is stored tightly packed instead of scattered throughout memory.

In Compiler Performance and LLVMIIUC, for typical programs, most of Rust compilation time is spent waiting for LLVM to spit out results.
There's a plan to use https://github.com/CraneStation/cranelift for debug builds instead of LLVM, which would make them faster at the cost of supporting fewer targets, and producing worse code.
