I don't think they are (or rather, will be) "officially tied to LLVM". > Interestingly, some other features of Rust are defined through C++ > or implemented similar to C++. Of course, Rust has inherited a lot of ideas from other languages. It is also not uncommon for specifications to refer to others, e.g. C++ refers to ~10 documents, including C; and C refers to some too. > Exception/unwind safety may be another subject that increases > the difficulty of writing unsafe Rust. Note that Rust panics in the kernel do not unwind. Cheers, Miguel
