    Bug#53593: Add some instrumentation to improve Valgrind sensitivity · 5fc862d6
    Marko Mäkelä authored
    BUILD/*: Add valgrind_configs=--with-valgrind.
    BUILD/*: Remove -USAFEMALLOC from valgrind_flags.
    
    configure.in: Add AC_ARG_WITH(valgrind) and HAVE_VALGRIND.
    
    include/my_sys.h: Define a number of MEM_ wrappers for VALGRIND_ functions.
    include/my_sys.h: Make TRASH do MEM_UNDEFINED().
    
    include/m_string.h: Remove unused macro bzero_if_purify(A,B).
    
    _mymalloc(): Declare MEM_UNDEFINED() on the allocated memory.
    
    _myfree(): Declare MEM_NOACCESS() on the freed memory.
    
    storage/innobase/include/univ.i: Enable UNIV_DEBUG_VALGRIND based on
    HAVE_VALGRIND rather than HAVE_purify.
    
    Possible things to do:
     * In my_global.h, remove the defined(HAVE_purify) condition
       from the _WIN32 uint3korr().
     * In my_global.h *int*korr(), use | instead of +
       in order to keep the Valgrind V bits accurate
     * Consider replacing HAVE_purify with HAVE_VALGRIND
     * Use VALGRIND_CREATE_BLOCK, VALGRIND_DISCARD in mem_root and similar places
