For UIA, they all map the same as aria-haspopup=true
Expose state of the pop-up activities as "expanded" or "collapsed" in the ExpandCollapseState property in the ExpandCollapse Control Pattern.
We might be able to do more in a later version of UIA, but not right now.

Cynthia, James,
Please send me the UIA and MacOSX mapping changes for the different values of aria-haspopup?
See: https://rawgit.com/w3c/aria/action2056/core-aam/core-aam.html#ariaHaspopupTrue
I have them for MSAA/IA2 and atk/atspi
Thanks,
Rich
