NetBSD Exploring LLVM's LLD Linker For Lower Memory Footprint
The NetBSD project has been making good progress in utilizing the LLVM compiler stack not only for the Clang C/C++ compiler but also for the different sanitizers, the libc++ standard library for C++, and other improvements most of which are working their way into the upstream code-bases. One area of NetBSD's LLVM support being explored most recently is using the LLD linker.
NetBSD is exploring the use of the LLVM LLD linker over GNU's ld linker due to the lower memory footprint. LLD generally goes through far less RAM than the current GNU ld linker.

Finding Compiler Bugs With C-Reduce
Support for a long awaited GNU C extension, asm goto, is in the midst of landing in Clang and LLVM. We want to make sure that we release a high quality implementation, so it’s important to test the new patches on real code and not just small test cases. When we hit compiler bugs in large source files, it can be tricky to find exactly what part of potentially large translation units are problematic. In this post, we’ll take a look at using C-Reduce, a multithreaded code bisection utility for C/C++, to help narrow done a reproducer for a real compiler bug (potentially; in a patch that was posted, and will be fixed before it can ship in production) from a real code base (the Linux kernel). It’s mostly a post to myself in the future, so that I can remind myself how to run C-reduce on the Linux kernel again, since this is now the third real compiler bug it’s helped me track down.

Intel Vulkan Linux Driver Adds Conditional Rendering, Draw Indirect Count
First up, the Intel Vulkan driver now supports VK_EXT_conditional_rendering after a lengthy review/revision process. VK_EXT_conditional_rendering was added to Vulkan 1.1.80 last July and allows for rendering commands to be made selective based upon a value in the buffer memory, in order to allow discard rendering commands based upon a result in GPU memory without having to wait on the application/engine. The conditional rendering can be used with Vulkan draws, compute dispatches, and clearing of attachments. VK_EXT_conditional_rendering is supported by Haswell "Gen 7.5" graphics and newer with the upcoming Mesa 19.0.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
