Bug ID: 159442
Summary: We should have different reserved zone sizes for JS
and host code.
Classification: Unclassified
Product: WebKit
Version: WebKit Local 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
There should be 2 separate reserved zone sizes for JS and host code (we currently only have one reserved zone size for both), and the JS code reserved zone size needs to be larger than the host code reserved zone size. For example, the JS reserved zone size needs to be large enough to provide sufficient CPU stack capacity for the max recursion taken by the parser to recurse when parsing any builtin. In contrast, the host code reserved zone size only needs to be large enough for one recursion entry into the parser.
