GCC 15 "Stage 1" Feature Development Ending Next Month

Richard Biener of SUSE published a GCC 15.0.0 status report for outlining the current development state of the GCC 15 open-source compiler as it works its way toward the stable GCC 15.1 release in the early months of 2025.

GCC 15 remains in "stage 1" development where feature development continues to happen. But the plan is to transition to the "stage 3" bug fixing mode beginning on 18 November. This is about normal with typically seeing the GNU Compiler Collection transition to its bug-fixing period each November as it works toward the official stable release in the early months of the following year.

As it stands now there are 31 P1 regressions as bugs of the highest priority. There are 621 P2 regressions, 171 P3 regressions, 206 P4 regressions, and 27 P5 regressions. All the details within today's status report on the GCC mailing list.

GCC 15.1 stable will likely be out in March~April if usual release timings hold. GCC 15 has seen AVX10.2 enablement work, un-deprecating of Itanium IA-64, more AMD Zen 5 optimizations, Zhaoxin "Shijidadao" x86_64 CPU support, NVIDIA Grace CPU tuning, Intel APX NF support, Xeon Phi support removed, updated Rust support, Ada language updates, and various C/C++ additions. We'll see in the next month what other language feature work may be queued up for GCC 15 and if any new Intel / AMD / Arm CPU targets get added for GCC 15.
