I think this is a toolchain bug. The code expects at least -march=armv8.2-a for dotprod extensions. But your CPU is armv8-a. The code here is responsible (part of GCC): https://github.com/gcc-mirror/gcc/blob/master/gcc/config/arm/arm_neon.h#L18187
may be related? https://bugs.gentoo.org/884497
i reinstalled the whole system, setting: -march=armv8-a+crypto+crc+lse+rcpc+rdma+dotprod+fp16fml+sb+ssbs+flagm+pauth in make.conf i was also able to install (during initial install) latest gcc: sys-devel/gcc-12.2.1_p20221210 (https://bugs.gentoo.org/884497).

The problem is that gcc detects armv8-a, but minimum is armv8.2-a for dotprod extension. Clang seems to automatically "fix" this. The detection code either looks for information in /proc/cpuinfo or uses a file from GCC_CPUINFO environment variable. Can you share the content of /proc/cpuinfo for one core?
