Correct way to access predecessors of a gimple statement?

Hi I am trying to implement a GVN algorithm as a plugin for GCC 4.6. With help from GCC IRC channel, internals doc and reading the source, I was able to get a prototype working for the case of a single block. Now, I am trying to handle the case of confluence of multiple edges i.e. obtain redunda

I have been following this discussion for quite a while now, guess it's the right time to introduce myself as one of the newcomers. I had attended the Abstractions in GCC workshop 2012 by Prof. Uday and his team. It definitely helped me kick start with understanding of GCC and got me interested; s

Global Value Numbering and dependence on SSA in GCC

Hi I am an undergraduate CS student and a beginner to GCC development. I am trying to implement a new algorithm for Global Value Numbering proposed recently in our research group. I have basic experience in implementing simple optimization passes as dynamic plugins in GCC. I have some questions r
