Hello, Where can I find documentation about the REAL_CST tree? Mine says FIX_ME... Actually I am trying to write the reals as they are given to the target file. 5.0 should appear as 5.0 in the target file. How can I do this? I have gone through mangle.c and the debug_tree function but for some reason I cannot use the function calls they use. I always get a linking problem. To top it up, I would like to use the std::ostream and its operators. Is there no macro to do something like : os << GET_VALUE << endl; ? Thanks for any answers, Primrose
