In a project of mine, I needed to run some code before any constructors

-z initfirst feature is perfect for this, but it only supports one shared
library.

Does -z initfirst affect just constructor execution, or symbol bindingas well?

As initfirst is currently defined for GNU, there can only be oneinitfirst library.
