A good starting point is the GCC WIKI at https://gcc.gnu.org/wiki - there's a
Getting Started with GCC Development section.  It's good to get one
self familiar
with building GCC from source and to see how to do edit/compile/debug cycles.

For the project in question you need to make yourself familiar with
the highlevel
compilation flow.  toplev.c is where the main controlling pieces stick together.
See do_compile -> compile_file -> symtab->finalize_compulation_unit -> compile
which will eventually lead to the "pass manager".  The ultimate task would be
to change the "pass manager" to execute chunks of passes in parallel and the
first hurdle is to identify chunks that can be executed in parallel without too
many changes (read: least global shared state).
