* However, its contents are used elsewhere as well, so we can't just modify this one function.
|
|

|
|
* The following code first searches for one of the patterns above, then replaces the
|
|
* "stb r28, 25(r1)" instruction that stores the wrong value on the stack with a branch instead
|
|
* That branch branches to the injected custom code ("li r3, 3; stb r3, 25(r1)") that stores the
|
|
* correct value (3) instead. At the end of the injected code will be another branch that branches
|
|
* 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
|
|
* afterwards anyways.
