Arkadi, I am not compiler developper but I learnt it from documentation and books
http://www.acm.uiuc.edu/sigmil/RevEng/ch02.html http://www.network-theory.co.uk/docs/gccintro/gccintro_82.html (please follow "next >>>" link) http://codingfreak.blogspot.com/2008/02/compilation-process-in-gcc.html http://www.csse.monash.edu.au/courseware/cse2302/2005/labs/lab1/gcc.html http://www.cs.cmu.edu/~mjs/123/lectures/Feb-25/makefiles.pdf http://gcc.gnu.org/onlinedocs/gccint/Passes.html#Passes Ok, you might be right in regard Java source code and bytecode. Well, I am not completely sure and it might be that you right that "C" is not "RTL" any more as it was years ago. Now it looks like "Language Source Code" -> AST -> RTL -> RTL optimization -> Assembly -> Linker -> Binary code. http://gcc.gnu.org/wiki/StructureOfGCC Sorry for some misleading information, I read documentation about internals of GCC compiler a few years (probably 6 years ago) and quite big changes happened since then. NOTE: I am not teaching but installing/configuring/suppoting IT infrastructure.
