cmp r0,99 // compare the number 99 with register r0
ldr r0,[r1,0] // load register r0 from the address pointed to by (r1 + (0 * ''size'')) where ''size'' is 8 bytes for 64-bit stores, 4 bytes for 32-bit stores
ldr w0,[r1,0] // like ldr above but reads one 32 bits only - note the use of w0 instead of r0 for the source register name ldrb w0,[r1,0] // like above but reads 1 byte (8 bits) only - note the use of w0 instead of r0 for the source register name
ldur r0,[r1,0] // load register r0 from the address pointed to by (r1 + 0) - the mnemonic means "load ''unscaled'' register"
mov r0,r1 // move data from r1 to r0
