Change or extend as you like.

Edit there is also __max, which has to be seen as hotfix.
The problem was, that max and min cannot be used as macro, it conflicted user methods with same name. Maybe we use just a global function instead when max and min are not defined respectively, this should be better than this hotfix now.

@tdd11235813 tdd11235813 changed the title Adds __popc. Adds __popc and __max Sep 19, 2019

Maybe this is better as a function-style macro (taking an argument explicitly) for consistency with others?
