The gcc version has been difficult to support and maintain, due mainly
to the fact that the GIMPLE intermediate language was never designed
for static analysis. The abstract syntax tree provided by Clang is an
easier data structure to work with for front-end analyses of this
kind. Moreover, the gcc implementation of annotalysis has some issues
that make an eventual merge into trunk somewhat unlikely, and
annotalysis is of little use to people outside of google as long as it
stays in google/main. The clang implementation has been in trunk from
Hope that explains it a bit better,
