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 binding
as well?


It's only about construction order.


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