There is a lot of duplicated code in the hooks implementation in the various front ends. I am trying to factor it a little bit.
I started with the builtin_function hook. Doing a mostly mechanical work I came up with the attached patch. The patch doesn't touches the C++ front end because it is organised a little differently and would require more work. I don't want to apply this patch right now because I think that it can be made a little better. To do this I need some clarifications: *) Why does a front end needs to know when a new builtin is added? *) If the internal representation used is language independent, can we change the signature of builtin_function to receive just the decl node? The next thing I will try to do is wrap all calls to lang_hooks.builtin_function in a add_builtin_function (in which file should it be?) and move the common code into it. Any comments? Thanks, Rafael
