gimplification---gimple tree for C and C++

Subject: gimplification---gimple tree for C and C++
Bcc:

I have two (maybe dummy) question here:

1) For C programs, gimplification is done in gimplify_function_tree(), which is called (through several caller layers) from toplev_main(). Can someone explain how gimplification is done for C++? Maybe another way to ask it is: I understand cc1 is generated from toplev_main(). But what is the "main entrance" for the compiler for C++ (cc1plus)?

2) If I want to have a procedure to walk the gimple tree for both C and C++ program, i.e., after the tree has been lowered to GIMPLE, where should I add it? I guess this question may be automatically explained after answering above question.

Thanks,
Sean
