Hi, I am planning to use tree-ssa branch of gcc for my project which involves some program analysis. I have tried to read all the documents related to tree-ssa. But I am not sure that the GENERIC grammer given in the gccsummit-2003-proceedings.pdf is complete or not. I have this doubt because when I see the implementation of few functions related to ssa, I see some NIY statements. Is anyone using the ssa branch for the some purpose ? If you know about this grammer, could you please clarify my doubt. -S
