Summary: Optimize LayoutUnit::boundedMultiply
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Platform
AssignedTo: webkit-unassigned at lists.webkit.org

LayoutUnit::boundedMultiply is used for multiplication that's prone to overflow and for all LayoutUnit multiplication if SATURATED_LAYOUT_ARITHMETIC is enabled. The current approach is quite inefficient.
Change it to use a more efficient saturated multiplication implementation.
