            Bug ID: 259429
           Summary: Empty switch statements generated by
                    opcode_generator.rb
           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: ian.grunert at gmail.com

AirOpcodeGenerated.h generates warnings when built with MSVC due to switch statements with no case clause (only default). This builds without warnings in clang but generates an extraneous jmp instruction to the next line.

Fix opcode_generator.rb to stop generating these empty switch statements.
