There's plenty of it, yes, but if you're going to attempt some heavy backend wizardry then you will have to get your head around most of it sooner or later. Unless you have a merged gcc-binutils tree (not likely if you downloaded it yourself) then you don't actually have any assemblers bundled. Instead, you have / Top level makefiles for cygnus toolchain /gcc C front end and generic backend /gcc/config CPU/OS specific instruction sets and ABIs /gcc/cp C++ front end /gcc/objc Objective-C front end /gcc/f Fortran front end /gcc/java Java front end /gcc/po Internationalization 'pot' translation files /gcc/intl Internationalization library /gcc/fixinc Fixes for non-standards-conformant system headers /gcc/doc Documentation /gcc/ginclude GCC build includes /gcc/testsuite GCC regression testsuite etc. plus a number of runtime libraries and helper libraries (libiberty) at the top level. i.e. you'll find the C-front end and the generic backend in the gcc directory, plus you'll need one of the machine description files (.md) plus a number of headers and source files in the config tree to tell the generic backend how to generate processor specific code. All documentation is build with GCC into at least .info format. It is also available online at http://gcc.gnu.org/onlinedocs/ Good luck! Rup.
