|
|
* That branch branches to the injected custom code ("li r3, 3; stb r3, 25(r1)") that stores the

|
|
* back to the instruction after the one that has been replaced (so, to "addi r4, r1, 0x18").
|
|
* r3 can safely be used as a temporary register because its contents will be replaced immediately
