package Err_Vars is
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.
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.
Warnings_Detected : Nat;
-- Number of warnings detected
Current_Error_Source_File : Source_File_Index;
-- 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.
Raise_Exception_On_Error : Nat := 0;
-- 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
-- Global Values Used for Error Message Insertions --
-- The following global variables are essentially additional parameters
-- passed to the error message routine for insertion sequences described
-- above. The reason these are passed globally is that the insertion
-- mechanism is essentially an untyped one in which the appropriate
-- variables are set dependingon the specific insertion characters used.
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_Qual_Level : Int := 0;
-- 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 := False;
-- 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.
