Detailed Description

Automatic dispatcher code for the XXH3 family on x86-based targets.

Optional add-on.

Compile this file with the default flags for your target. Do not compile with flags like -mavx*, -march=native, or /arch:AVX*, there will be an error. See XXH_X86DISPATCH_ALLOW_AVX for details.
