Can you link the PR? I am interested in getting it merged. I assume you are referring to code generator at https://github.com/rust-lang/rust/tree/master/src/etc/platform-intrinsics https://github.com/rust-lang/rust/tree/master/src/etc/platfo.... I haven't touched that code, but if you think hand editing is preferrable to code generator in terms of maintenance, and everybody agrees, I am sure it can be deleted and generated code be hand edited from now on. For others, here is an example PR adding AVX compare and blend to Rust, and how does change to JSON and change to generated Rust code compare: https://github.com/rust-lang/rust/pull/32231 https://github.com/rust-lang/rust/pull/32231
