class DIEValueList

Declaration

class DIEValueList { /* full declaration omitted */ };

Description

A list of DIE values. This is a singly-linked list, but instead of reversing the order of insertion, we keep a pointer to the back of the list so we can push in order. There are two main reasons to choose a linked list over a customized vector-like data structure. 1. For teardown efficiency, we want DIEs to be BumpPtrAllocated. Using a linked list here makes this way easier to accomplish. 2. Carrying an extra pointer per \a DIEValue isn't expensive. 45% of DIEs have 2 or fewer values, and 90% have 5 or fewer. A vector would be over-allocated by 50% on average anyway, the same cost as the linked-list node.
