Mrustc: a Rust compiler written in C++

Then better stop using LLVM on Rust.

Until then, those comments only annoy those of us that happen to like Rust, but don't find it mature enough to replace C++ on the use cases we happen to care about.

I didn't say you can't write useful software in C++. I said that C++ software is not, in general, memory safe. Sometimes the benefits of a particular piece of software (for example, having an excellent production-grade optimizer) outweigh its drawbacks (for example, not being memory-safe).

I don't think you'd find a single LLVM developer who would claim that LLVM is memory safe. Giving invalid IR to LLVM and not running the verifier frequently segfaults it, for example...

I do agree with that, but that is exactly why I always mention the "C with C++ compiler" idiom, which is usually followed by your remark.
