.global _start _start: mov R1,#1 mov R2,#2 cmp R1,R2 BGT bigger BLT _default ; If you didn't add this. bgt bigger will be useless instruction bigger: mov R0,#4 B end _default: mov R0,#3 end: mov R7,#1 swi 0 ;I'm not similar to arm's syntax at all,sorry! >.<

You won't know the result if you don't test it More: bgt >> jg & blt >> jl would be better Now You can remove "bigger: ,BGT bigger" for optimize of your program but certainly unreadable
