https://gcc.gnu.org/ml/gcc-patches/2017-09/msg00587.html During the last round, the last comment given was that the reviewer wasn't going to dive deep into this code, as it's essentially converting between the different representations and is code that I'd be maintaining. As this is code that other gcc maintainers will be potentially looking after as well, I'd like any glaring problems to be dealt with immediately. Iain.
