I am a recently LLVM user, and I found that LLVM is hard to use at first
sight. It would be nice if people like me can have documents like "howto"
but code-oriented (versus manual-oriented). Something like code extracts
with common (and basic) problems.

Last URL is a document to generate code from scratch until a "Module", and I
need generate it from a "Module" thru native code....

... and nothing of these cover this topic.

(If I am wrong get right me!!)

Looking................ (each dot is a minute)

Well, these examples are JIT-based. I really need generate into memory
native code, extract the address of a function (aka "main") and execute it.

Apologize my inexperience with LLVM, but I *really* don't find an example to
generate code into memory from a "Module".
