I've not checked the actual numbers but I think in terms of line count, that assembly may be the same function done multiple times for different (sub-)architectures for different generations of Arm and Intel chips that have different vector instructions.

Yes, there are currently 4 copies of the assembly - for AVX2, SSSE3, 64-bit NEON, and 32-bit NEON. There will likely be more as future architectures get added.
