What's the text you're checking for here? Again, just being paranoid that:
```
R_ARM_LDR_PC_G0
random_symbol
R_SOMETHING_ELSE
foo1
```

Would match this too.

If they are on the next line you can do ARM-NEXT: and lit will make sure there's no extra stuff there, or regex is an option if you've got stuff in between that varies e.g. offsets and the like.
