WebMost ARM mnemonics consist of three letters, e.g. SUB, MOV, STR, STM. Certain 'optional extras' may be added to slightly alter the affect of the instruction, leading to mnemonics such as ADCNESand SWINE. The … That makes sense for a fixed insn-length ISA like ARM (vs. x86's harder-to-decode insns that can do base+idx*scale + 8bit or 32bit signed displacement, with each of the components being optional). The +/- bit is probably the same one that affects the index, so it kinda makes sense for it not to work as another bit of a 2's complement number.
