GCC 17 Feature Development Ends Next Week

GCC 17 leaves “stage one” feature development on Nov. 15 and shifts to bug fixing, Phoronix reports. SUSE’s Richard Biener announced the plan.

What’s landed in GCC 17

• AVX10V1AUX support, and Function Multi-Versioning for AVX10.2 and APX.
• -mtune=native and -mcpu=native on RISC-V, plus SpacemiT X100 targeting.
• Initial support for the AI Compute Extensions (“ACE”) and more AMD Zen tuning.
• 128-bit atomics and early C++29 infrastructure.

Stage four (regression fixes only) usually starts around January, and GCC 17.1 should land around April.

God Bless, and Use the Source!
