I didn't personally, but libgcc thus built was tested by a colleague who has access to engineering samples of some of those machines and they confirm icelake is properly detected. We didn't test gcc's -march=native detection. The numbers come from the Linux kernel header: https://github.com/torvalds/linux/blob/master/arch/x86/include/asm/intel-family.h#L77-L81 which in turn come from the Intel SDM, vol. 4,. The May 2019 edition has the most up-to-date values. LLVM's compiler-rt equivalent: https://github.com/llvm-mirror/compiler-rt/commit/ 787bbab3e844b25bd3f8f282c6d3c8b3ad892fb4 https://github.com/llvm-mirror/compiler-rt/commit/ 7a65a376f3ae2d770797eb87b7556a3689a6177a -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products
