• Manu (9/9) Oct 06 2019 I need a pause() function in druntime (wrap x86 `pause`/arm `yield`,
• Stefan Koch (3/14) Oct 06 2019 intrinsics go into core.bitOp
• Adam D. Ruppe (2/3) Oct 06 2019 pause has nothing to do with bits though...
• Stefan Koch (3/6) Oct 06 2019 neither does atomic load and store.
• Manu (4/11) Oct 06 2019 Too late the party, it's in core.atomic. I reckon that's the most

Candidates are:
  core.atomic - seems odd, but it's almost exclusively used when
implementing spin locks
  core.thread - sounds appropriate, but doesn't really mean anything wrt threads
  core.sync.??? - no appropriate sub-package appears to exist...

Ideas?
I'm leaning towards core.atomic.

intrinsics go into core.bitOp

Atomic Load and Store are there as well :)

neither does atomic load and store.

or writing to input/output ports.

Too late the party, it's in core.atomic. I reckon that's the most
sensible location.
