Yes, I understand that. I've worked on JITs and fancier compilers in the (long) past, and I'm aware of inlining and devirtualization. My question is what is special about the code that is written into memory by code generation that distinguishes it by code written into memory at program startup. I can't think of anything off the top of my head that would make inlining dynamically generated code impossible, short of possibly not wanting to toss away already jitted code
