Jim Keller has remarked that there are about 25 instructions in common use that all instruction sets need. Let’s talk about them.
mov was about 40%push was about 10%pop was about 4%call was about 7%ret was about 7%je/jne was about 3%jmp was also 3%cmp was 5%add/sub was 10%and/or/xor was 5%lea was 3%nop was about 3%This is about the same for ARM and RISC-V, where moving instructions were most dominant.
