global main
section text
main:
@ Initialize registers
mov r # @ Counter for Fibonacci sequence
mov r # @ Current Fibonacci number
mov r # @ Previous Fibonacci number
mov r # @ Number of Fibonacci terms to compute
mov r # @ Loop counter
@ Allocate memory for Fibonacci sequence
ldr rfibonaccisequence
mov r # @ Size of each element in bytes
fibonacciloop:
@ Store current Fibonacci number in memory
str rr r
@ Calculate next Fibonacci number
add r r # @ Increment loop counter
cmp r r @ Compare loop counter with total terms
beq endfibonacci @ Exit loop if all terms are computed
@ Calculate next Fibonacci number using recursion
bl fibonaccirecursive
b fibonacciloop @ Repeat loop
endfibonacci:
@ Exit program
mov r # @ Exit syscall
mov r # @ Exit status
svc @ Call kernel
fibonaccirecursive:
@ Recursive Fibonacci calculation
push lr @ Save return address
sub r r # @ Decrement term counter
cmp r # @ Check if term is or
blo oneorzero
@ Calculate Fibonacci number
mov r r
add r r r @ Fn Fn Fn
mov r r @ Update previous Fibonacci number
@ Restore return address and return
pop pc
oneorzero:
@ Handle base cases Fibonacci sequence starts with
mov r r @ Set F
b endrecursive
endrecursive:
pop pc @ Return from recursive call
section data
fibonaccisequence:
skip @ Space for Fibonacci numbers bytes each
the code is not working I tried running it on onlinegdb
