Will clangs custom int size feature ever get added to gcc?

Question

I was wondering whether clang's new amazing custom size (things like 13-bit int, or 70-bit int, etc.) will get added to gcc.

Answer 1

No most likely, it won't. That is because clang uses llvm as its compiling backend, and gcc doesn't. The llvm backend is what allows clang to pull off that feat. LLVM allows from 1 to 16,777,215 bit ints.
