GCC Patches Posted For Implementing Incremental LTO
GCC Patches Posted For Implementing Incremental LTO

Michal Jires of SUSE posted a new set of patches on Friday for implementing Incremental LTO support for the GNU Compiler Collection. The goal here with Incremental LTO is for reducing compile times while doing quick edit-compile cycles while employing Link-Time Optimizations.

GCC COBOL Compiler Support Continues To Be Worked On
GCC COBOL Compiler Support Continues To Be Worked On

While not as popular as Rust or other languages these days, for COBOL enthusiasts and those continuing to maintain codebases in this 50's programming language, the out-of-tree GCC COBOL compiler support continues to be worked on in late 2023.

GCC 14 Now Honors The -std=c23 & -std=gnu23 Compiler Options For C23
GCC 14 Now Honors The -std=c23 & -std=gnu23 Compiler Options For C23

While the next revision of the C standard won't see its formal publishing until the 2024 calendar year, the ISO C standards committee already decided on keeping "C23" as the informal name for this next major C update. As such, with today's GCC 14 Git the -std=c23 compiler option for targeting C23 is now honored along with -std=gnu23 for the GNU dialect of C23.

Glibc Dynamic Loader Hit By A Nasty Local Privilege Escalation Vulnerability
Glibc Dynamic Loader Hit By A Nasty Local Privilege Escalation Vulnerability

A nasty vulnerability has been made public today concerning Glibc's dynamic loader that can lead to full root privileges being obtained by local users. This affects Linux distributions of the past two years with the likes of Ubuntu 22.04 LTS, 23.04, Fedora 38, and others vulnerable to this local privilege escalation issue.

Glibc Lands HWCAPs Support For LoongArch
Glibc Lands HWCAPs Support For LoongArch

When it comes to Glibc HWCAPs for allowing the C library to load optimized libraries based upon the CPU features at run-time, it's mostly been focused on the x86_64 world for targeting higher x86-64 levels or being able to load optimized libraries for systems with AVX support. Loongson though has now contributed initial LoongArch HWCAPs support.

New Maintainer Steps Up For GCC Compiler's MIPS CPU Port
New Maintainer Steps Up For GCC Compiler's MIPS CPU Port

With development of the MIPS architecture having officially ended two years ago in favor of focusing on RISC-V for future CPU designs and the overall decline of that CPU architecture, it's been years since the GNU Compiler Collection (GCC) has seen its MIPS code well maintained. However, now a capable developer has stepped up willing to serve as the GCC maintainer for MIPS.
