    [TurboFan] Avoid Gcc compilation fail by Initializing rest_index variable. · ce138669
    zhengxing.li authored
      The CL #38858 (https://codereview.chromium.org/2269293004) removed the parameter assignment code
      in rest_parameter(int* index) function in Class DeclarationScope.
    
      This caused the Gcc compilation fail at the following code in src/compiler/ast-graph-builder.cc, line 576.
      int rest_index;
      Variable* rest_parameter = scope->rest_parameter(&rest_index);
      BuildRestArgumentsArray(rest_parameter, rest_index);
    
      The error message was:
      ../src/compiler/ast-graph-builder.cc: In member function ‘void v8::internal::compiler::AstGraphBuilder::CreateGraphBody(bool)’:
      ../src/compiler/ast-graph-builder.cc:578:54: error: ‘rest_index’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
      BuildRestArgumentsArray(rest_parameter, rest_index);
                                                          ^
    
      This CL fixed this issue by intializing rest_index to 0.
