Bug ID: 140804
Summary: If we inline a nested function call, we should be able
to do GCSE on closure variable accesses and object
allocation sinking on the activation
Classification: Unclassified
Product: WebKit
Version: 528+ (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
I'm pretty sure that this won't work right now because we don't reason about the activation that a NewFunction* operation references. But we totally should do this.
This would be a poor man's way of doing single-and-loving-it analysis: http://www.cs.purdue.edu/homes/suresh/papers/popl98.ps.gz
