IIRC, the entire section of global TLS data is initialized, and is all contiguous memory, so it would be anti-performant to initialize all but 4 bytes.

    int x2;

These are both TLS and they init to different values, I suppose:

    float f2prime = void;

would mean f2prime is 0 and not float.init. Otherwise what you state is kind of what I was expecting.


struct X
  int a;
  int b = void; // also initialized to 0.

This is because X must blit an init for a, and it would be silly to go through the trouble of blitting X.init to a, but not b. Especially, for instance, if you had an array of X (you'd have to blit every other int!)


Thanks for the bonus example.
