I am currently trying to understand how rtl creation is accomplished.  And, I
have a few questions.

Exactly what is an insn?  This is a big mistery to me.

If I were to write a front-end to a compiler and wanted to use gcc's rtl, what
functions or macros would be most important for creating the initial rtl?  Is
the tree stuff necessary?

Is there any more documentation available other than the texinfo files and the
code?

I ask these questions because I am currently working on a compiler project and
am ready for the code generation step.  I have gcc up on my machine and could
use its rtl if I can interface it with my parser, symbol table, etc.  Thanks
for any help or suggestions anyone can offer.
