This is interesting — a compiler/runtime that makes almost all standard C/C++ code completely memory safe. The performance overhead is not negligible, but there are plenty of cases where “rewrite it in rust” still isn’t a practical solution.

Here's an updated list of C/C++ programs that are totally memory safe because I ported then to Fil-C. In many cases they requires zero changes or just small cosmetic changes! - musl libc - libc++ (C++) - libc++abi (C++) - WG14 signals - libuev - icu4c (C++) - zlib - bzip2 -
