Just a simple question out of curiosity.

Is https://blog.rust-lang.org/2023/11/09/parallel-rustc.html already usable with cg_clif?

Most of this happens before involvement of the codegen backend. This part should works just fine. The LLVM backend also does translation from MIR to LLVM ir in parallel. cg_clif doesn't yet do the translation from MIR to clif ir in parallel.
