Fix #9647: Set correct enum value (#2856) * Tokenize: Set varId for variables in enum Set varIds in enum values. It was previously disabled in 5119ae84b879fad to avoid issues with enums named the same as global variables. Take care to only set varids to variables used to set the value of an enumerator, not the enumerator itself. This is somewhat complicated by the fact that at the time this happens, astOperand1(), astOperand2(), astParent() etc are not set. The current implementation is not perfect, for example in the code below, y will not have a varid set, but x and z will. This is deemed sufficient for now. int x, y, z; enum E { a = f(x, y, z); }; * Fix #9647: Value of enums with variables as init values C++ allows enum values to be set using constexprs, which cppcheck did not handle before. To solve this, add a new pass to valueflow to update enum values after global consts have been processed. In order to do so, I moved all settings of enum values to valueflow. After setting the enum values, we need another call to valueFlowNumber() to actually set users of the enums. There is still room for improvements, since each pass of valueFlowGlobalConstVar() and valueFlowEnumValue() only sets variables that are possible to set directly, and not if setting the value of a variable allows us to set the value of another. For example constexpr int a = 5; constexpr int b = a + 5; enum E { X = a }; constexpr E e = X; Here both b and e will not have their values set, even though cppcheck should be possible to figure out their values. That's for another PR though. This was tested by running test-my-pr.py with 500 packages. The only difference was one error message in fairy-stockfish_11.1, where cppcheck now printed the correct size of an array instead of 2147483648 which I assume is some kind of default value. In that package, using a constexpr when setting enum values is common, but as mentioned, there was no change in the number of warnings.

Fix #9647: Set correct enum value (#2856) * Tokenize: Set varId for variables in enum Set varIds in enum values. It was previously disabled in 5119ae84b879fad to avoid issues with enums named the same as global variables. Take care to only set varids to variables used to set the value of an enumerator, not the enumerator itself. This is somewhat complicated by the fact that at the time this happens, astOperand1(), astOperand2(), astParent() etc are not set. The current implementation is not perfect, for example in the code below, y will not have a varid set, but x and z will. This is deemed sufficient for now. int x, y, z; enum E { a = f(x, y, z); }; * Fix #9647: Value of enums with variables as init values C++ allows enum values to be set using constexprs, which cppcheck did not handle before. To solve this, add a new pass to valueflow to update enum values after global consts have been processed. In order to do so, I moved all settings of enum values to valueflow. After setting the enum values, we need another call to valueFlowNumber() to actually set users of the enums. There is still room for improvements, since each pass of valueFlowGlobalConstVar() and valueFlowEnumValue() only sets variables that are possible to set directly, and not if setting the value of a variable allows us to set the value of another. For example constexpr int a = 5; constexpr int b = a + 5; enum E { X = a }; constexpr E e = X; Here both b and e will not have their values set, even though cppcheck should be possible to figure out their values. That's for another PR though. This was tested by running test-my-pr.py with 500 packages. The only difference was one error message in fairy-stockfish_11.1, where cppcheck now printed the correct size of an array instead of 2147483648 which I assume is some kind of default value. In that package, using a constexpr when setting enum values is common, but as mentioned, there was no change in the number of warnings.
