            Bug ID: 195798
           Summary: [WTF] Remove redundant std::move in StringConcatenate
           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: xan.lopez at gmail.com

GCC (since 9.x when -Wredundant-move is enabled by default) warns of two redundant move operations in StringConcatenate. AFAICT the issue is that C++ will already do an implicit move when a local value is returned and copy (or move) elision is not applicable, as in here.
