The 'info gcc' says for __attribute__((constructor)):

  `constructor'
     The `constructor' attribute causes the function to be called
     automatically before execution enters `main ()'. 

That's *all* gcc promises. No guarantees of exactly when they are
called, nor in which order.

Reading gcc source would let you know what a particular version of
gcc does, but not what guarantees there are. If it's not in the
manual, assume it's not specified.
