Bug ID: 229329
Summary: Remove assertIsTagged and assertIsNullOrTagged.
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: mark.lam at apple.com
These assertion utility functions relies on tagged pointers always having non-zero PAC bits. This is an incorrect assumption. A tagged pointer can have PAC bits that are completely zero. Hence, these assert functions cannot be made to work reliably. We should remove them to prevent them from being used, and potentially resulting in flaky assertion failures that will hard to debug later.
