You need to check out the GCC source code from version control and find the files and functions referenced in there (locating pieces of GCC code using find, grep, etc. on the GCC source tree is something you'll need to do a lot), and make sure you can build GCC, run the testsuite, save results from a testsuite run, build and run the testsuite and compare the results of the two runs (this is something that would need doing very many times in the course of any project working on GCC). -- Joseph S.
