   // TODO(rmcilroy): List of things not currently dealt with here but done in
   // fullcodegen's prologue:
   //  - Support profiler (specifically profiling_counter).
   //  - Call ProfileEntryHookStub when isolate has a function_entry_hook.
   //  - Allow simulator stop operations if FLAG_stop_at is set.
   //  - Deal with sloppy mode functions which need to replace the
   //    receiver with the global proxy when called as functions (without an
   //    explicit receiver object).
   //  - Code aging of the BytecodeArray object.
-  //  - Supporting FLAG_trace.
-  //
-  // The following items are also not done here, and will probably be done using
-  // explicit bytecodes instead:
-  //  - Allocating a new local context if applicable.
-  //  - Setting up a local binding to the this function, which is used in
-  //    derived constructors with super calls.
-  //  - Setting new.target if required.
-  //  - Dealing with REST parameters (only if
-  //    https://codereview.chromium.org/1235153006 doesn't land by then).
-  //  - Dealing with argument objects.
 
   // Perform stack guard check.
