sl@0: The directory containing this files contains ARM's example
sl@0: implementation of the EHABI which is part of 'The Base Standard ABI
sl@0: for the ARM architecture'. All parts of this specification including
sl@0: the code contained here can be obtained via the link
sl@0: [http://www.armdevzone.com/EABI/HomePage.html]. Symbian's
sl@0: implementation of exception handling is derived from this code. This
sl@0: file will document the amendments made to each file to integrate the
sl@0: code with SymbianOS.

sl@0: Implementation Notes.
sl@0: 
sl@0: * The Symbian implementation does not support nested exceptions. This
sl@0:   is not required by C++ and there is no extant requirement to support
sl@0:   language which does require nested exceptions.  However this means
sl@0:   that the Symbian implementation is not fully BSABI compliant.

sl@0: * Remove the source region unwinder_c and replace unwind_activity_c with _DEBUG.
sl@0: * Replace inclusion of stddef.h with e32def.h
sl@0: * Add typedef for size_t (as a consequence of replacement of stddef.h).
sl@0: * Add declaration for abort().
sl@0: * Add declaration for bsearch().
sl@0: * Replace use and declaration of printf() with DebugPrintf().
sl@0: * Conditionalize nested exception handling with SUPPORT_NEST_EXCEPTIONS and abort if found.
sl@0: * Remove __ARM_ETInfo from __UnwindRaiseException.
