Bug ID: 166988
Summary: Heap uses pointers way too much
Classification: Unclassified
Product: WebKit
Version: WebKit Nightly Build
Hardware: All
OS: All
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: fpizlo at apple.com
The Heap uses pointers in a lot of places where we would ordinarily use references. In JSC we use references when:
- Not pointing to the JSC heap. (Most of Heap's pointers are not heap pointers.)
- The pointer is immutable.
- Using references would not introduce lots of * to & (and vice-versa) conversions.
- The pointer is non-null.
Under these rules, we could move most of Heap's pointers to references. I think we should do it all at once or in a short burst of patches right next to each other.
