static RPCHelpMan getchaintips ( )

static

Idea: The set of chain tips is the active chain tip, plus orphan blocks which do not have another orphan building off of them. Algorithm:

Make one pass through BlockIndex(), picking out the orphan blocks, and also storing a set of the orphan block's pprev pointers.
Iterate through the orphan blocks. If the block isn't pointed to by another orphan, it is a chain tip.
Add the active chain tip
