With the GCC 15 compiler having progressed to its final stage of development prior to the GCC 15.1 stable release in the likely March~April time frame, I've begun testing the updated GNU Compiler Collection on some test systems.

With the GCC 15 compiler having progressed to its final stage of development prior to the GCC 15.1 stable release in the likely March~April time frame, I've begun testing the updated GNU Compiler Collection on some test systems. Today's tests were done on an AMD EPYC 9575F Supermicro server running Ubuntu 24.10 with the Linux 6.13 kernel. For those wondering how GCC 14/15 is comparing to the latest LLVM Clang compiler code, those comparison benchmarks will be published next week with today simply looking at how GCC 15 is performing relative to the current GCC 14 stable compiler.
