Actually, nowadays Arm describes the ISA as a load-store architecture. The RISC vs. CISC debate is, in my opinion, pretty pointless nowadays and I'd prefer if we'd just stop using these words to describe ISAs.

Hey, if you can't write "ADD [r0], r1" but have instead to do "LDR r2, [r0]; ADD r2, r1; STR [r0], r2", it means it's still RISC.
