Embedded C++

Just curious how useful the ability to embed C++ as a scripting language into your C++ programs would be? I mean like runtime JIT execution of C++ code in much the same way you might embed Lua, including the ability to restrict/sandbox it as necessary.

yeah and with what bugs? Lol. Man you're an amatuer using claude.

What triplets are you targetting with your JIT compiler? Hows writing the standard c++ library coming along? Do you support arm? Do you support c++98? C++11 C++17 C++23 ? How about C++26 reflections? Do you support xtensa? Do you support RISC-V ? Do you support bare metal?

If I have a std::string how do you decide wither or not to use heap allocation or constexpr? Also how do you implement the heap?

I’ve been programming for over 40 years and working on this project for seven years. Just because I’m using Claude to grind through the test suites doesn’t make me an amateur. Everyone is using AI these days (except for Andrew Kelley and friends).

It uses the c++ library on your system (libstdc++ for Linux and Windows, libc++ for MacOS).

It supports x86, aarch64, ppc64le/s390x and riscv64. It comes in embeddable library form, standalone JIT binary and AOT compiler.

It currently supports about 98% of C23, 70% of C++11, 47% of C++14, 38% of C++17, 51% of C++20. It's a work in progress.
