This means that they can keep -- track of the current node being worked on, with the entry call setting -- a new value, by pushing the Node_Id value on a stack, and the exit call -- popping this value off. Atree.Current_Error_Node is set by both the -- entry and exit routines to point to the current node so that an abort -- message indicates the node involved as accurately as possible. procedure Debug_A_Entry (S : String; N : Node_Id); pragma Inline (Debug_A_Entry); -- Generates a message prefixed by a sequence of bars showing the nesting -- depth (depth increases by 1 for a Debug_A_Entry call and is decreased -- by the corresponding Debug_A_Exit call). Then the string is output -- (analyzing, expanding etc), followed by the node number and its kind. -- This output is generated only if the debug A flag is set. If the debug -- A flag is not set, then no output is generated. This call also sets the -- Node_Id value in Atree.Current_Error_Node in case a bomb occurs. This -- is done unconditionally, whether or not the debug A flag is set. procedure Debug_A_Exit (S : String; N : Node_Id; Comment : String); pragma Inline (Debug_A_Exit); -- Generates the corresponding termination message. The message is preceded -- by a sequence of bars, followed by the string S, the node number, and -- a trailing comment (e.g. " (already evaluated)"). This output is -- generated only if the debug A flag is set. If the debug A flag is not -- set, then no output is generated. This call also resets the value in -- Atree.Current_Error_Node to what it was before the corresponding call -- to Debug_A_Entry. end Debug_A;
