Setting the CPU flag after a comparison doesn't do anything useful yet, you also need to perform an addition with 1 or do nothing depending on the flag, and selecting between these two options is usually done with a conditional branch, unless the CPU can execute ALU instructions conditionally (ARM can do this, x86 only has conditional mov AFAIK).

You can copy a flag in the al register then add that. That's usually what the compiler generates.

Also, apparently ARM64 did drop the conditional instructions (somehow I missed the memo):
