Hi guys, I've been trying to provide a special #pragma directive to allow a dynamic declaration of intrinsics as builtin function in GCC 4.0.1. e.g. #pragma builtin my_nice_intrinsic I've already implemented the mechanism using the lang_hooks.builtin_function, and it seem to work correctly. Unfortunately, I need to extend this mechanism with non-standard intrinsics which represent assembly instruction with more than one output (e.g. 4 outputs). Builtin functions return only one value and the argument list is only take as input, and I not able to find/build the correct way to modify them. It is possible to use a different templete (maybe similar of that one used for assembler inlining) as builtin_function declaration or someone has idea if this "dynamic" extension is feasible ? I'm also trying to "explore" the functionality of BUILT_IN_FRONTEND and BUILT_IN_NORMAL, but I've not found documentation (if we exclude to navigate the source codes :-( ). Thanks, Claudio
