WebJun 15, 2024 · These instructions have a reach of approximately ±16MB. Windows uses Thumb-2 exclusively, so you won’t see the blx instruction used in this way. The X stands for “exchange”, which means that it swaps between Thumb-2 and classic ARM modes.² The return address is stored in lr, but with the bottom bit set. There’s a reason for this. WebSep 11, 2013 · Thumb-2 can make use of the same conditional execution features that the Arm instruction set provides. For conditionally executing one or two instructions, this mechanism can provide code-size and performance benefits over the (more conventional) conditional branching mechanism.
