A curiosity. Compiling an empty file yields a binary that has 1.4M, what’s in there? I have no idea about LLVM, but observe that --emit llvm-ir generates a file that has approximately 100K lines! I can recognize there at least some stuff related to the core of Crystal itself. Also, see names of th…

You also could build with --no-debug to remove debug symbols for production binaries, which would reduce the size a bit more. It’s also possible to give your own prelude file, or b…

I’m sure, a similar question has been asked before, but I’m unable to dig it up. This SO question is somewhat related, though: Crystal-lang: why is the LLVM “hello.bc” not the same if generated by Crystal or by clang? Looking at the prelude points in the right direction, but doesn’t answer this ent…

That is an extraordinary response, thanks very much! What about the second question? The one about the size with —release option? (To be clear, I am using an empty program as a mean/exercise to discover what is the minimum included. Such a program is of little practical interest and does not deser…
