Status: RESOLVED FIXED

(Core :: JavaScript Engine: JIT, enhancement, P4)

Description

[Denis Palmeiro [:denispal]]

A suggestion by :jmuizelaar is to make the Trampoline symbol more clear rather than have a blanket "Trampolines" name.

e.g.

   - 3.23% js::jit::SetElementMegamorphic                                                                                                                                                                                       
      - 3.18% Trampoline: VM Wrapper                                                                                                                                                                                                  
         - 0.49% Trampoline: Arguments Rectifier                                                                                                                                                                                
            - 0.09% IC: Call scripted func                                                                                                                                                                                                  
               - 0.02% BaselineInterpreter
