[^disassembly]: On Linux, to disassemble a compiled program, you can call `objdump -d {path-to-binary}`.

Note that the two snippets above are not just syntactically different. Both are optimized codes produced by a compiler, but the Arm version uses 4 instructions, while the x86 version uses 3. The `add eax, [rdi]` instruction is what's called *fused instruction* that does a load and an add in one go — this is one of the perks that the [CISC](../isa#risc-vs-cisc) approach can provide.
