In addition to the upcoming GCC 15 stable compiler release bringing a COBOL language front-end, much better Rust support, revamped AVX10 support, and other shiny new language features and hardware supports, there are also some more fundamental usability improvements for developers.
Red Hat compiler engineer David Malcolm wrote a blog post today outlining some of the usability improvements to be found in the upcoming GCC 15.1 stable release.
Some of the usability improvements with GCC 15 include prettier execution paths, a new appearance for showing C++ template errors, machine readable diagnostic outputs, C23 transition improvements, and a revamped color scheme. There is also now libgdiagnostics as a shared library for the GCC diagnostics subsystem that can be reused by other projects.
More details on these usability improvements coming with GCC 15 via the Red Hat Developer Blog.
