| -- Error Counts -- |
| ------------------ |
| |
| Serious_Errors_Detected : Nat; |
| -- This is a count of errors that are serious enough to stop expansion, |
| -- and hence to prevent generation of an object file even if the |
| -- switch -gnatQ is set. Initialized to zero at the start of compilation. |
| |
| Total_Errors_Detected : Nat; |
| -- Number of errors detected so far. Includes count of serious errors and |
| -- non-serious errors, so this value is always greater than or equal to the |
| -- Serious_Errors_Detected value. Initialized to zero at the start of |
| -- compilation. |
| |
| Warnings_Detected : Nat; |
| -- Number of warnings detected. Initialized to zero at the start of |
| -- compilation. |
| |
| ---------------------------------- |
| -- Error Message Mode Variables -- |
| ---------------------------------- |
| |
| -- These variables control special error message modes. The initialized |
| -- values below give the normal default behavior, but they can be reset |
| -- by the caller to get different behavior as noted in the comments. These |
| -- variables are not reset by calls to the error message routines, so the |
| -- caller is responsible for resetting the default behavior after use. |
| |
| Error_Msg_Qual_Level : Int; |
| -- Number of levels of qualification required for type name (see the |
| -- description of the } insertion character. Note that this value does |
| -- note get reset by any Error_Msg call, so the caller is responsible |
| -- for resetting it. |
| |
| Warn_On_Instance : Boolean; |
| -- Normally if a warning is generated in a generic template from the |
| -- analysis of the template, then the warning really belongs in the |
| -- template, and the default value of False for this Boolean achieves |
| -- that effect. If Warn_On_Instance is set True, then the warnings are |
| -- generated on the instantiation (referring to the template) rather |
| -- than on the template itself. |
| |
| Raise_Exception_On_Error : Nat; |
| -- If this value is non-zero, then any attempt to generate an error |
| -- message raises the exception Error_Msg_Exception, and the error |
| -- message is not output. This is used for defending against junk |
| -- resulting from illegalities, and also for substitution of more |
| -- appropriate error messages from higher semantic levels. It is |
| -- a counter so that the increment/decrement protocol nests neatly. |
| |
| Error_Msg_Exception : exception; |
| -- Exception raised if Raise_Exception_On_Error is true |
| |
| Current_Error_Source_File : Source_File_Index := Internal_Source_File; |
| -- Id of current messages. Used to post file name when unit changes. This |
| -- is initialized to Main_Source_File at the start of a compilation, which |
| -- means that no file names will be output unless there are errors in units |
| -- other than the main unit. However, if the main unit has a pragma |
| -- Source_Reference line, then this is initialized to No_Source_File, |
| -- to force an initial reference to the real source file name. |
| |
| ---------------------------------------- |
| -- Error Message Insertion Parameters -- |
| ---------------------------------------- |
| |
| -- The error message routines work with strings that contain insertion |
| -- sequences that result in the insertion of variable data. The following |
| -- variables contain the required data. The procedure is to set one or more |
| -- of the following global variables to appropriate values before making a |
| -- call to one of the error message routines with a string containing the |
| -- insertion character to get the value inserted in an appropriate format. |
| |
| Error_Msg_Col : Column_Number; |
| -- Column for @ insertion character in message |
| |
| Error_Msg_Uint_1 : Uint; |
| Error_Msg_Uint_2 : Uint; |
| -- Uint values for ^ insertion characters in message |
| |
| Error_Msg_Sloc : Source_Ptr; |
| -- Source location for # insertion character in message |
| |
| Error_Msg_Name_1 : Name_Id; |
| Error_Msg_Name_2 : Name_Id; |
| Error_Msg_Name_3 : Name_Id; |
| -- Name_Id values for % insertion characters in message |
| |
| Error_Msg_Unit_1 : Name_Id; |
| Error_Msg_Unit_2 : Name_Id; |
| -- Name_Id values for $ insertion characters in message |
| |
| Error_Msg_Node_1 : Node_Id; |
| Error_Msg_Node_2 : Node_Id; |
| -- Node_Id values for & insertion characters in message |
| |
| Error_Msg_Warn : Boolean; |
| -- Used if current message contains a < insertion character to indicate |
| -- if the current message is a warning message. |
| |
| end Err_Vars; |
