armv8 defines the registers for changing endianness too :) https://developer.arm.com/documentation/den0024/a/ARMv8-Regi... Cortex cores at least do support switching endianness for data in userspace (SCTLR_EL1.E0E)

Yeah, Cortex and NVIDIA cores do (and probably quite some others).

However, Apple-designed recent cores don’t implement big endian support at all.
