      Implement fastpath for proxy trap setPrototypeOf · fc8c4ef2
      Z Nguyen-Huu authored
      ObjectSetPrototypeOf and ReflectSetPrototypeOf are now Torque builtins (previously CPP) and the Proxy path is implemented completely in Torque while everything else calls into runtime (and is thus a bit slower than previously).

      [torque] Add lint errors for unused variable and label bindings · 0e53739c
      Simon Zünd authored
      This CL adds lint errors when 'let' bindings, arguments and labels
      are not used. Note that errors for 'const' bindings will be added
      later.
      
      In cases where arguments are actually needed to match the signature,
      the warning can be silenced by prefixing identifiers with "_". This
      might be needed for generic specializations or builtins called from
      TurboFan. Trying to use a variable or label that was marked with
      "_" results in a compilation error.
      
      Implicit arguments are not linted. They are implemented using exact
      string matching. Prefixing an implicit argument with "_" in a callee
      would break all callers as the names would no longer match.
      
      Drive-by: Fix all new lint errors in the existing Torque code.
