Sorry to nag, but how is outputting to LLVM bitcode not interpreting? You are taking source code and turning it into intermediate form (i.e. LLVM bitcode), no?

An interpreter means a program that runs a program, straight from its source code.

A compiler transforms a program from one format into another. decac does not execute programs, so it's not an interpreter.

LLVM bytecode does not exist after linking - it turns into usual machine code. It is not even a JIT compiler, talk less of an interpreter.
