You’re not forced to use all instructions of more complex ISAs. E.g. isn’t there an equivalent ARM instruction for each RISC-V one?

- 0x000xca0xfe 4y agoGood point, I forgot A64 laptops are already widely available! I only worked with old ARM chips and remember that the instruction endianness and the thumb mode were particularly nasty, so maybe this is the reason I didn't like it :) But most other tools do need to support everything. E.g. the IAR debugger I used really didn't like the thumb mode. But somebody still had to implement it either way -- that time could have been spent on improving other parts of the debugger.
