How Hooks Work
gdFunc:
mov x11, x30 ; backup original link register
bl trampoline
trampoline:
ldr x9, =0x2
lsl x9, x9, #32
ldr x10, =0x80000000
orr x9, x9, x10
ldr x9, [x9]
br x9 ; jump to 0x280000000void *findTheHook() {
void *target;
asm("mov %[t], x16" : [t] "=r"(target));
// now target contains [base + offset]
