...But how many of those instructions are just variants of other instructions, but with a different addressing mode?

- lgeek 10y agoFair enough, some instructions have many variants. But I work with ARM assembly almost daily and I still wouldn't remember that, for example, 'VQRDMULH' is a real instruction and it stands for 'Vector Saturating Rounding Doubling Multiply Returning High Half'.
- qwertyuiop924 10y agoAh, yes. A fun one. Those exist in x86, too. I should probably count up x86 against ARM, so I have more than guesses to go on here. Maybe that part of x86 actually better.
