Procedure Call and Return Instructions Far Call -- Procedure Call (lcall) the offset is popped by a near ret instruction within the procedure. On ARM, there is no "ret" instruction like on X86 or some other architectures. ARM return instructions manually move a value into the PC. For example, the "pop {r7, pc}" instruction at the end of the function in the screenshot above actually acts as a return instruction. This instruction pops values from the stack into the specified registers.

ARM's branch and link instruction, BL, automatically saves the return address in the register R14 (i.e. LR). We can use MOV PC, LR at the end of the subroutine to return back to the instruction after the subroutine call BL SUBROUTINE_NAME. A SUBROUTINE_NAME is a label in the ARM program.
