Hello Everyone, I am trying to add a specialized RTL into GCC. The main point of this RTL is to add specialized instructions during scheduling (so there is no specific regions such as every basic block or every function beginning/end where I can predict ahead of time before scheduling to insert). So what are the steps necessary for me to acomplish this? Any help is greatly appreciated, Thanks, Balaji V. Iyer. PS. Please CC me in your response since I am not subscribed to this mailing list. -- Balaji V.
