Haiku updates kernel compiler |
|
The Haiku team has been working on a new toolchain for building the kernel. The kerel was previously built with the GNU Compiler Collection, version 2. With an upgrade to version 8 of the compiler backward compatibility with BeOS drivers may be lost. However, it seems no one is using old BeOS drivers with Haiku anymore. "Waddlesplash made the kernel always build with gcc8, even on 32-bit systems. It was built with gcc2 until now, but it was not possible to use BeOS drivers anymore since the introduction of SMAP and other features, which led to slight changes in the driver ABI. No one complained, so there is no reason to preserve BeOS driver compatibility further. This should result in performance improvements for 32-bit installations, as the new compiler is much better at optimizing code. And it will allow kernel developers to use more modern C++ features." Additional changes coming to Jaiku are covered in the project's newsletter. |
