Adding alternatives (perhaps not usable now for no one but the interested reader): LLVM decided to start building their own last year: https://llvm.org/docs/Proposals/LLVMLibC.html

This great news, thanks a lot!

Looks like llvm-libc is being written in C++. Which is... odd.

Why ist that odd? It makes lots of sense to manage resources via RAII for example. C++ has really good C interop too.

It forces you to include a C++ compiler in your toolchain, which might not be possible for older systems, etc.

Every system has a C++ compiler nowadays, and if they do not, you have plenty options to compile yourself one.

No they don't.

Do you have an example? Keep in mind that we are not talking about the host platform here, but the target platform.

Not a problem for LLVM since it's linker is always a cross-linker so if you're targetting a new (or only use the older platform as a compile target) then the initial cross-compile will be able to produce the binaries. If the older system can't support the LLVM toolchain memory wise or otherwise then it's not really a problem either.

You only need a C++ compiler to build llvm-libc itself. You do not need a C++ compiler to use it in your C program.

Why? libc is just an interface, you can implement it however you want.

Microsoft did the same thing for the Universal CRT.

Of course they did.
