// PURPOSE: This header should be imported by every  file in Valgrind
// which needs specific behaviour when running as an "inner" Valgrind.
// Valgrind can self-host itself (i.e. Valgrind can run Valgrind) :
// The outer Valgrind executes the inner Valgrind.
// For more details, see README_DEVELOPPERS.
//--------------------------------------------------------------------

#include "config.h" 

// The code of the inner Valgrind (core or tool code) contains client
// requests (e.g. from helgrind.h, memcheck.h, ...) to help the
// outer Valgrind finding (relevant) errors in the inner Valgrind.
// Such client requests should only be compiled in for an inner Valgrind.
// Use the macro INNER_REQUEST to allow a central enabling/disabling
// of these client requests.
#if defined(ENABLE_INNER)

// By default, the client requests 
// undefine the below to have an inner Valgrind without any annotation.
