This is now integrated to ELVM as the Unlambda backend.
This is an Unlambda version of @shinh's C -> Brainfuck compiler.
8cc.unl is a C compiler in Unlambda. This is generated from C code by the BFS-targeted 8cc and BFS assembly -> Unlambda translator.
Unfortunately, compiled Unlambda program is slower than Brainfuck. It takes ~37 hours and >10GB memory to self-compile 8cc by 8cc.unl.
