On: QBE – Compiler Back End

Although unfortunately not open source proper, vbcc[0][1] is interesting.

QBE (and Eigen) are compiler kits, i.e. useful if you implement your own compiler. There are a lot of open-source C compilers already available for nearly any architecture.

Fair. But note that while not a "compiler kit", VBCC has front/backend separation. This is why I mentioned it.

Of course, as it isn't open source, third party backends/frontends are unlikely to occur.

Fortunately, despite not open source, the code and documentation can still be studied.
