It appears that branches will execute the target instruction then single step to the next instruction in one go, instead of single stepping to the target instruction. + +For example, if a blt should land on 13371234, stepping over the branch will land on 13371238. The instruction at 13371234 still executes, but this is not the behaviour on a baremetal Mac OS system. +Additional information: +A <a href="https://i.imgur.com/f6dguMt.png">screenshot</a> before the branch. +A <a href="https://imgur.com/WoVDtN7.png">screenshot<a/> after pressing 't' to step over the branch.
