[LLVMdev] recommendation books on code generation?

[Reed Kotler]

I don't think you need any special books.

There is nothing complicated going on that is not in a basic compiler 
book. Mostly you have to understand how they implemented basic things in 
this framework.

Knowing modern C++ (i.e. templates, overloading, etc...) and STL pretty 
well is more important than knowing about compiler theory in order to 
understand things.

The documentation online just needs to be read many times and you need 
to do your own port or try and understand one for an architecture that 
you already know pretty well.

http://llvm.org/docs/ProgrammersManual.html
http://llvm.org/docs/

You need to know what a phi node is. That is about the only thing that 
is mostly something you could not just learn from reading the code 
because it's a special term.
