This is an Ada compiler based on LLVM, connecting the GNAT front-end to the LLVM code generator to generate LLVM bitcode for Ada and to open the LLVM ecosystem to Ada. https://github.com/AdaCore/gnat-llvm LICENSE: GPL-3+
Given it seems to (for now) require LLVM 16 and we're currently on 19, I'm not too interested in it at this point.
