Well, this is not completely true. As said, JIT employs absolute addresses a lot, and for instance, you can use `lea` to compute the absolute address of a variable at runtime (with PC-relative addressing mode). Said that, I still see `movab

I understand that they refer to it as a fixed-length instruction set, it's correct, note though that not all ARMv8 instructions are 4 bytes long. Indeed, some instructions that are met together are fused to a single one, or SVE, for in

I think it moderately depends on the definition you give it to. If you require RISC to be a load/store architecture, x86 is not even close to be one. Also, aarch64 is a variable-length instructions set and include complex instructions
