Task Description

Environment

Operating System: [Ubuntu 20.04] Compiler Version: [gcc 9.4.0] CVA6 Version: [SHA:7f4549f2]

When compiling CVA6 with Verilator 5.008, a lint warning is generated due to the Symbol matching C++ keyword: 'operator'. Since verilator generates behavioral C++ Models, it's better to avoid C++ keyword names in the SV Code. We have to change this at different places within the code, what's the suggestion here ?

%Warning-SYMRSVDWORD: cva6/core/include/ariane_pkg.sv:551:35: Symbol matches C++ keyword: 'operator'
  551 |         fu_op                     operator;
      |                                   ^~~~~~~~

Description of Done

Lint Warning should be removed.
