Re : "bounds checking extension to gcc-3.0.4"

[Olatunji Oluwabukunmi Ruwase <tjruwase at stanford dot edu>]

hello,
 i am computer science grad student and i am working on a project which
is based on a previous work by Richard Jones and Paul Kelly. Their work
added a bounds checking extension to gcc 2.7., subsequently a patch for
this for gcc-2.9.5.2 has also being implemented.
 so i embarked on this project with the expectations that will be a
trivial exercise, only to find out that so much has changed in terms of
underlying implementation from gcc-2.9.5.2 and gcc-3.0.4 in terms of AST
representations, function defn  parsing, source files e.t.c.
 so far its being quite a painful and slow process for what it is merely
supposed to be a first phase of a compiler optimisation project.
 i am very new to the open source/gnu/gcc community so pardon my lengthy
mail and unconventional approach,but i 'll appreciate any sort of support
your team offers e.g in terms of directing to relevant documents which
detail the evolution of gcc versions

thanks
