Does league of legends also set a breakpoint for the "ret" hook?
The game will replace the ret instruction of a Nt* syscall export with an int3 in some cases. And expects its vectored exception handlers to handle it.
Also, do you plan to get those patches into wine-staging? Because I probably also should rewrite by patch for hookable x64 thunks to work like that.
Since they are required for LoL some variant of them should probably be committed. I am waiting to make sure they don't break Wine in some way for people.
