The traceback shows the locations of --- calls in the call chain, up to either the top or a designated --- number of levels. - --- The traceback information is in the form of absolute code locations. --- These code locations may be converted to corresponding source locations --- using the external addr2line utility, or from within GDB. - --- In order to use this facility, in some cases the binder must be invoked --- with -E switch (store the backtrace with exception occurence). Please --- refer to gnatbind documentation for more information. - --- To analyze the code locations later using addr2line or gdb, the necessary --- units must be compiled with the debugging switch -g in the usual manner. --- Note that it is not necessary to compile with -g to use Call_Chain. In --- other words, the following sequence of steps can be used: - --- Compile without -g --- Run the program, and call Call_Chain --- Recompile with -g --- Use addr2line to interpret the absolute call locations (note that --- addr2line expects addresses in hexadecimal format). - --- This capability is currently supported on the following targets: - --- All x86 ports --- AiX PowerPC --- HP-UX --- Irix --- Solaris sparc --- Tru64 --- VxWorks PowerPC --- VxWorks Alpha - -with System; -with Ada.Exceptions.Traceback; - -package GNAT.Traceback is - pragma Elaborate_Body; - - subtype Code_Loc is System.Address; - -- Code location used in building tracebacks - - subtype Tracebacks_Array is Ada.Exceptions.Traceback.Tracebacks_Array; - -- Traceback array used to hold a generated traceback list - - ---------------- - -- Call_Chain -- - ---------------- - - procedure Call_Chain (Traceback : out Tracebacks_Array; Len : out Natural); - -- Store up to Traceback'Length tracebacks corresponding to the current - -- call chain.
