Bug ID: 167161
Summary: [B3] B3 strength reduction could encounter Value
without owner in PureCSE
Classification: Unclassified
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: utatane.tea at gmail.com
B3 strength reduction clears existing value->owner in specializeSelect.
Thus, PureCSE's stored value `match` may not have `owner`.
This is caused in webassembly.org's demo.
