This one. Supporting new languages is, in principle, very simple. In theory, there is nothing special to be done. Every FE already generates gimple and that's what we are writing to the bytecode files. However, FEs may leave some language data in some expression/type/symbol nodes. These need to be cleared out by pass_ipa_free_lang_data. FEs that need to remove language data, need to implement a special langhook. I expect that FEs that use their own parsing data structures, will need to do little. OTOH, FEs that use 'tree' and are tied to C/C++ may need some work. I have not tested Fortran at all, that's why I'm not even trying to enable LTO with it. In theory, there should be little, if anything to do there. If I have some time before I finish merging LTO into mainline, I may try to enable Fortran. Of course, I welcome any and all help in this area. Diego.
