#include <stdint.h> uint32_t A[]={1,2,3,4,5,6}; int main() { shiftArray(A,6); while(1); } void shiftArray(uint32_t *ary, uint32_t size) { uint32_t value1,value2; value2 = 0; while(size != 0) { value1 = *ary; *ary = value2; value2 = value1; ary++; size--; } }

Sure, here is the equivalent assembly code for the given C program, written for the TM4C123:

    .syntax unified
    .cpu cortex-m4

    .data
A:  .word 1, 2, 3, 4, 5, 6   @ Data array A

    .text
    .global main
    .type main, %function
main:
    @ Push registers to the stack
    push {r4-r11, lr}

    @ Call shiftArray function with A and 6 as arguments
    ldr r0, =A
    mov r1, #6
    bl shiftArray

loop:
    b loop     @ Infinite loop

    @ Pop registers from the stack and return
    pop {r4-r11, pc}

    .type shiftArray, %function
shiftArray:
    @ Push registers to the stack
    push {r4-r11, lr}

    @ Initialize value2 to 0 and loop until size is 0
    mov r4, #0
    loop:
        cmp r1, #0
        beq end_loop
        @ Load value1 from the current element of ary
        ldr r5, [r0]
        @ Store value2 to the current element of ary
        str r4, [r0]
        @ Update value2 to value1 and increment ary and decrement size
        mov r4, r5
        add r0, r0, #4
        sub r1, r1, #1
        b loop
    end_loop:

    @ Pop registers from the stack and return
    pop {r4-r11, pc}

Note that this is just one possible implementation, and there may be other ways to write the same program in assembly language.
