Anton,
The compiler I'm writing uses the LLVM API to generate LLVM-IR directly which
is just-in-time compiled to executable code.
Using (setq XXX (COMPILE nil (lambda (x) (* 3 x)))) returns a compiled function
that can be evaluated directly using (FUNCALL XXX 4) --> 12.
There are no intermediate compilers that need to be run to generate executable
code.
I am guided by my own interest to learn/try my own Common Lisp --> LLVM
implementation.
Best,
.Chris.
