'''SAMPLE INPUT:
0x0000555555557f18│+0x0018: 0x00007ffff7f93500  →  <seccomp_init+0> endbr64
0x0000555555557f20│+0x0020: 0x00007ffff7da0430  →  <__errno_location+0> endbr64
'''
'''CAVEATS:
1. This will overwrite func/var names if anything goes awry.
2. x86_64 only.
3. Will mess up if null-offsets on the GOT table are included.
This was written on a whim during X-MAS CTF 2020.
