In LLVMweekly [1], I read the following:
"You may be be interested, amazed, and/or horrified to learn of
constexpr-8cc [2]. It provides a compile-time C compiler
implemented as C++14 constant expressions."
The constexpr compiler is generated using ELVM [3], a C
compiler that targets a bunch of other languages (instead of
targeting machine code). The constexpr compiler was built by
adding a C++14-constexpr target to ELVM. [4]
A fun project: add a D CTFE backend? ;)
cheers,
Johan

mixin(import("myCode.d"));
Even better because it doesn't have to output the program at
runtime, the generated executable *is* the compiled code ;). I
guess that's just the same as #include though....
If you want to compile to other languages, just use the above
with ldc --output-ll or --output-bc, then get an llvm decompiler
to get that to your target language :)
A C compiler using ctfe, now that would take some more work.
