Usability improvements in GCC 9

David Malcolm wrote a really nice blog post on Usability improvements in GCC 9 describing nicer looking diagnostics, the JSON output format, simpler C++ errors, tracking down bad initializations, optimizer diagnostics and new fix-it hints.

Perhaps a deeper change is that we now have a set of user experience guidelines for GCC, to try to keep a focus on the programmer’s experience as we implement new diagnostics. If you’d like to get involved in GCC development, please join us on the GCC mailing list. Hacking on diagnostics is a great way to get started.
