It's also usable as a library in a way GCC isn't. That's why Apple started using it with their OpenGL software drivers back in the day. That's why almost all modern and new programming languages use LLVM, and those that don't do not use GCC.
That's out of date, libgccjit exists. LLVM is a bit difficult to use as a library because it has no stable API and is in C++ so it doesn't have a stable ABI either.
Hmm.. why is it called "jit"? That seems like it's telling everyone the use case is very different from LLVM. Also the big EXPERIMENTAL banner doesn't instill confidence. Unlike with LLVM which is used by dozens of production languages.
