it would be impacted, but not in the way you think. static libs we'd compile |
| 13 |
with -fPIE while dynamic libs we'd compile with -fPIC. these flags share a |
| 14 |
lot, but they aren't exactly the same. -fPIE allows a few assumptions over - |
| 15 |
fPIC which, for some code bases, improves performance. |
