Upstream, rice it down!

Filed under
Gentoo

While Gentoo often gets a bad name because of the so-called ricers and upstream developer complains that we allow users to shoot themselves in the foot by setting CFLAGS as they please, it has to be said that not all upstream projects are good in that regard. For instance, there are a number of projects that, unless you enable debug support, will force you to optimise (or even over-optimise) the code, which is obviously not the best of ideas (this does not count in things like FFmpeg that rely on Dead Code Elimination to link properly — in those cases we should be even more careful but let’s leave it alone for now).

Now, what is the problem with forcing optimisation for non-debug builds? Well, sometimes you might not want to have debug support (extra verbosity, assertions, …) but you might still want to be able to fetch a proper backtrace; in such cases you have a non-debug build that needs to turn down optimisations. Why should I be forced to optimise? Most of the time, I shouldn’t.

Over-optimisation is even nastier:

  • Device Tailored Compositors with Qt Wayland at CLAAS E-Systems
    Have you heard about software in cars that run on embedded devices? Do you think that creating such software might be challenging? Well, welcome to a complete new world of complexity, welcome to the world of agriculture machines! For many years, automatic steering (on fields), terminals to control the complex mechanical operations of a self-driving 16 ton combine harvester on a soft ground, and self-optimization systems to optimize any tiny bit of your harvester, are key demands from customers. I, myself, am working at CLAAS E-Systems, the electronics and software department within the CLAAS group. Our group is well known for being among the leading manufacturers for combine harvesters, tractors and forage harvesters.
  • Qt Wayland Is Next Appearing On Tractors & Farm Equipment
    With Qt 5.8's Qt Wayland Compositor Framework taking shape, more developers are beginning to tailor a Qt Wayland compositor to their use-cases. One of those is a company specializing in farm equipment like combine harvesters, tractors, and harvesters. As a guest post on the official Qt blog, developer Andreas Cord-Landwehr of CLAAS E-Systems talked up Qt Wayland for their purposes in the highly-regulated agriculture industry.
  • KDevelop 5.1 Open-Source IDE Launches with LLDB and OpenCL Support, Many Changes
    The development team behind the popular, open-source, cross-platform, free and powerful KDevelop IDE (Integrated Development Environment) were proud to announce the official release and general availability of KDevelop 5.1. KDevelop 5.1 is now the most advanced stable version of the application, which is written entirely in Qt and designed to be used on various GNU/Linux distributions that usually ship with the KDE Plasma desktop environment, but also on the latest releases of the Microsoft Windows operating system.
