--- This package provides a method for generating a traceback of the
--- current execution location. The traceback shows the locations of
--- calls in the call chain, up to either the top or a designated
--- number of levels.

--- We must turn polling off for this unit, because otherwise we get
--- elaboration circularities with System.Exception_Tables.

- -- the current call chain.
- --
- -- Traceback is the address of an array of addresses where the
- -- result will be stored.
- --
- -- Max_Len is the length of the Traceback array. If the call chain
- -- is longer than this, then additional entries are discarded, and
- -- the traceback is missing some of the highest level entries.
- --
- -- Len is the returned actual number of addresses stored
- -- in the Traceback array.
- --
- -- Exclude_Min/Exclude_Max, if non null, provide a range of addresses
- -- to ignore from the computation of the traceback.
- --
- -- On return, the Traceback array is filled in, and Len indicates
- -- the number of stored entries. The first entry is the most recent
- -- call, and the last entry is the highest level call.
