Since the mutability of HeapNumbers is determined by their owning object's descriptor array, we can remove the MutableHeapNumber type entirely, at the cost of a few fewer DCHECKs and a couple of TODOs to use the descriptor array information. This is a necessary step towards a follow-up which allows in-place Double -> Tagged transitions Design doc: https://docs.google.com/document/d/1VeKIskAakxQFnUBNkhBmVswgR7Vk6T1kAyKRLhqerb4/ Bug: v8:9606 Change-Id: I13209f9c86f1f204088f6fd80089e17d956b4a50 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1743972 Commit-Queue: Leszek Swirski <leszeks@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Reviewed-by: Michael Starzinger <mstarzinger@chromium.org> Reviewed-by: Toon Verwaest <verwaest@chromium.org> Cr-Commit-Position: refs/heads/master@{#63294} |

Heap Stats
Heap stats is a HTML-based tool for visualizing V8-internal object statistics. For example, the tool can be used to visualize how much heap memory is used for maintaining internal state versus actually allocated by the user.
The tool consumes log files produced by d8 (or Chromium) by passing
--trace-gc-object-stats or a trace captured using Chrome's tracing
infrastructure. Chrome trace files can either be processed as gzip or raw text
files.
Hosting requires a web server, e.g.:
cd tools/heap-stats
python -m SimpleHTTPServer 8000
