> One of the interesting things about the ARM instruction set […] is that ALL instructions, not just branch, were conditional, which meant that you could avoid the need for branch instructions in some cases - rather than conditionally branch past some instructions, just make them conditional and "execute" them regardless. Smaller code and faster execution! I think both can be debated. It took 4 bits out of each 32-bit instruction to specify those condition flags. That’s 12.5% of the bits in each instruction that could have been used for other stuff such as supporting more registers and larger immediate constants, both of which could speed up code. It was an interesting idea, though. Simple to implement and useful at times.
