Bug ID: 173975
Summary: WTF::Thread should have the threads stack bounds.
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Web Template Framework
Assignee: webkit-unassigned at lists.webkit.org
Reporter: keith_miller at apple.com
There are a number of places in JSC that try to walk another threads stack. Currently, the stack bounds are stored on ThreadData but that's in TLS so other threads cannot see it. Right now we get the stack bounds by iterating the MachineThreads looking for our target thread then getting it's stack bounds. We should just put the stack bounds on the Thread.
