Details

An extension of bug 1519298, I would like to be able to see the memory usage broken down by AllocKind.

The use case is when I'm looking at either memory growth, in which case it would help narrow down what is growing, or when comparing two scenarios with differing memory usage and I want to know what types of things are causing it. I'm hoping AllocKind will be a useful level of granularity; in the limit, you'd want to know (in the case of objects) the class of the object or the allocation site or whatever. But for me, I've wanted it for strings vs objects vs shapes, and AllocKind will give me that.
