During holidays, I rebased and updated the patch, which is originally created by Simon[1] (Thanks so much!). And now, I’ve landed it into the upstream.
The concept of this patch is, if ENABLE(MALLOC_HEAP_BREAKDOWN) is enabled, WebKit creates MallocZone for each kind of allocation.
For example, Vector uses VectorMalloc allocator now. Which is FastMalloc allocator in production build. But if ENABLE(MALLOC_HEAP_BREAKDOWN) is enabled,
VIRTUAL RESIDENT DIRTY SWAPPED ALLOCATION BYTES DIRTY+SWAP REGION
MALLOC ZONE SIZE SIZE SIZE SIZE COUNT ALLOCATED FRAG SIZE % FRAG COUNT
