Bug ID: 140805
Summary: Sink function allocations, and then the activation
allocation, to a point where we know that let-bound
variables are initialized - and then allow those
functions' code to be optimized without TDZ checks
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
The optimizing compiler already has the ability to sink allocations to the point where they escape. Doing this for activation and function allocations would enable us to prove cases where the function cannot see the TDZ of some let-bound variables.
