Bug ID: 160792
Summary: OverridesHasInstance should not branch across register
allocations.
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
The OverrideHasInstance node has a branch test that is emitted conditionally. It also has a bug where it allocated a register after this branch. Because the branch isn't always emitted, this bug has gone unnoticed until now. Will fix.
