- -- Note: the following subprograms are used in a stack like manner, with
- -- an exit call matching each entry call. 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. Comperr.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 Comperr.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
- -- Comperr.Current_Error_Node to what it was before the corresponding call
- -- to Debug_A_Entry.
