Bug ID: 186473
Summary: [DFG] ArraySlice should support arguments types
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
So frequent use of Array#slice is converting arguments to arrays by
var slice = Array.prototype.slice;
slice.call(arguments);
Our DFG pipeline only supports ArraySlice with JS Array types. JSC DFG should support ArraySlice with arguments.
