Arm/load

There is a 32-bit word located at memory location (address) 0x345678. Write a function that reads this word from memory and returns it. Note that the function has no parameters: It loads a word from a hard-coded location.

int load ();

Expected solution length: Around 3 lines.

Sample Input

Memory [0x345678] initialized to 123. No input to function.

Sample Output

.global _start
_start:
    ldr r0, =0x345678
    ldr r1, =123
    str r1, [r0]
    movw r0, #0xbad   // This function has no parameters.
    movw r1, #0xbad   // So destroy the value here so you won't be tempted to use it.
    bl load
    1: b 1b    // Done

.global load
load:
