                    register coloring allocator
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: msaboff at apple.com

For large Wasm functions, the graph coloring register allocator uses O(N^2) space where N is the number of temps in the Air IR.  We need to reduce the space required by large functions.
