Authored by stellaraccident on Oct 9 2020, 11:51 AM.


  • Isolates the visibility controlled parts of its implementation to a detail namespace.
  • Applies a struct level visibility attribute which applies to the static local within the get() functions.
  • The prior version was not emitting a symbol for the static local "instance" fields when the user TU was compiled with -fvisibility=hidden.
