GCC: Optimizing Linux, the Internet, and Everything

Filed under
Development
GNU

Software is useless if computers can't run it. Even the most talented developer is at the mercy of the compiler when it comes to run-time performance - if you don’t have a reliable compiler toolchain you can’t build anything serious. The GNU Compiler Collection (GCC) provides a robust, mature and high performance partner to help you get the most out of your software. With decades of development by thousands of people GCC is one of the most respected compilers in the world. If you are building applications and not using GCC, you are missing out on the best possible solution.

GCC is the “de facto-standard open source compiler today” [1] according to LLVM.org and the foundation used to build complete systems - from the kernel upwards. GCC supports over 60 hardware platforms, including ARM, Intel, AMD, IBM POWER, SPARC, HP PA-RISC, and IBM Z, as well as a variety of operating environments, including GNU, Linux, Windows, macOS, FreeBSD, NetBSD, OpenBSD, DragonFly BSD, Solaris, AIX, HP-UX, and RTEMS. It offers highly compliant C/C++ compilers and support for popular C libraries, such as GNU C Library (glibc), Newlib, musl, and the C libraries included with various BSD operating systems, as well as front-ends for Fortran, Ada, and GO languages. GCC also functions as a cross compiler, creating executable code for a platform other than the one on which the compiler is running. GCC is the core component of the tightly integrated GNU toolchain, produced by the GNU Project, that includes glibc, Binutils, and the GNU Debugger (GDB).

LLVM Lands Support For ARMv8.5's Branch Target Identification

  • LLVM Lands Support For ARMv8.5's Branch Target Identification (BTI)

    A bulk of the Linux/open-source enablement we have seen taking place for ARM's new ARMv8.5 architecture revision is around its new Spectre defenses to help SoCs that will begin shipping later in 2019.

    Back in September the first of the ARMv8.5 support began landing in the LLVM/Clang compiler and it's work to battle Spectre-style vulnerabilities. That work included speculation restriction system registers, a new speculation barrier, prediction invalidation instructions, and SSBB/PSSBB speculation barriers. ARMv8.5 also brings some additions outside of the Spectre/security space like new persistent memory instructions and random number instructions.

1080p Linux Gaming Performance - NVIDIA 415.22 vs. Mesa 19.0-devel RADV/RadeonSI

Stemming from the recent Radeon RX 590 Linux gaming benchmarks were some requests to see more 1080p gaming benchmarks, so here's that article with the low to medium tier graphics cards from the NVIDIA GeForce and AMD Radeon line-up while using the latest graphics drivers on Ubuntu 18.10. This round of benchmarking was done with the GeForce GTX 980, GTX 1060, GTX 1070, and GTX 1070 Ti using the newest 415.22 proprietary graphics driver. On the AMD side was using the patched Linux 4.20 kernel build (for RX 590 support) paired with Mesa 19.0-devel via the Padoka PPA while testing the Radeon RX 580 and RX 590. Read more

Leftovers: Linux in the Ham Shack and Golden Age of the iPhone Is Ending

  • LHS Episode #264: The Weekender XXI
    Welcome to the 21st Weekender episode of Linux in the Ham Shack. This time around, we talk about the few contests and special event stations that are around for December. We also touch on Linux distros to try, things to do in the amateur radio and open source world and then we dive straight into hedonism, discussing good food, good music and good spirits. Thank you for listening and Happy Holidays.
