As a first step, let's: - Require types to opt-into compact pointer usage, instead of assuming all pointers can be compacted/packed in the same way. - Add alternate allocator paths for types that are used in compact pointers, giving us a new API point to control how they are allocated in the future. 1998059 1 d_degazio 2023-12-08 10:54:59 -0800 Pull request: https://github.com/WebKit/WebKit/pull/21517 1998283 2 ews-feeder 2023-12-09 00:33:09 -0800 Committed 271796@main (27959d8049ad): <https://commits.webkit.org/271796@main> Reviewed commits have been landed.
