Just pasting a small snippet from that here:
line: 1755
```
  if (req == PTRACE_GETREGS) {
    GetRegister(pid, GPR0, &(((GPR *)data)->r0));
    GetRegister(pid, GPR1, &(((GPR *)data)->r1));
    GetRegister(pid, GPR2, &(((GPR *)data)->r2));
    GetRegister(pid, GPR3, &(((GPR *)data)->r3));
    GetRegister(pid, GPR4, &(((GPR *)data)->r4));
    GetRegister(pid, GPR5, &(((GPR *)data)->r5));
    GetRegister(pid, GPR6, &(((GPR *)data)->r6));
    GetRegister(pid, GPR7, &(((GPR *)data)->r7));
    GetRegister(pid, GPR8, &(((GPR *)data)->r8));
    GetRegister(pid, GPR9, &(((GPR *)data)->r9));
    GetRegister(pid, GPR10, &(((GPR *)data)->r10));
