[Valgrind-users] VALGRIND_DO_CLIENT_REQUEST

[Yakir B. S. <Yak...@mo...>]

Hi,
I moving my code from 32bit to 64bit and the pointers changed from 4 
bytes to 8 bytes.
I try to you valgrind function   VALGRIND_DO_CLIENT_REQUEST .
my code send to this function void*.
It failed on cast from 8 bytes of pointer to unsigned int (4 bytes).
my code :
  void markAsUnaccessible(void* address, size_t size)
   {
     VALGRIND3_DISCARD(VALGRIND3_MAKE_NOACCESS(address,size));
   }

#define VALGRIND3_DISCARD(_qzz_blkindex)                          \
    (__extension__ ({unsigned int _qzz_res;                       \
     VALGRIND3_DO_CLIENT_REQUEST(_qzz_res, 0 /* default return */, \
                             VG3_USERREQ__DISCARD,                 \
                             0, _qzz_blkindex, 0, 0, 0);          \
     _qzz_res;                                                    \
    }))


   #define VALGRIND3_DO_CLIENT_REQUEST(                               \
         _zzq_rlval, _zzq_default, _zzq_request,                   \
         _zzq_arg1, _zzq_arg2, _zzq_arg3, _zzq_arg4, _zzq_arg5)    \
   { volatile unsigned int _zzq_args[6];                           \
     volatile unsigned int _zzq_result;                            \
     _zzq_args[0] = (unsigned int)(_zzq_request);                  \
     _zzq_args[1] = (unsigned int)(_zzq_arg1);                     \
     _zzq_args[2] = (unsigned int)(_zzq_arg2);                     \
     _zzq_args[3] = (unsigned int)(_zzq_arg3);                     \
     _zzq_args[4] = (unsigned int)(_zzq_arg4);                     \
     _zzq_args[5] = (unsigned int)(_zzq_arg5);                     \
     __asm__ volatile(__SPECIAL_INSTRUCTION_PREAMBLE               \
                      /* %EDX = client_request ( %EAX ) */         \
                      "xchgl %%ebx,%%ebx"                          \
                      : "=d" (_zzq_result)                         \
                      : "a" (&_zzq_args[0]), "0" (_zzq_default)    \
                      : "cc", "memory"                             \
                     );                                            \
     _zzq_rlval = _zzq_result;                                     \
   }


can you help?
I try find solution over the internet and i see that many users have - 
VALGRIND_DO_CLIENT_REQUEST
as this code :
#define VALGRIND_DO_CLIENT_REQUEST(                               \
           _zzq_rlval, _zzq_default, _zzq_request,                   \
           _zzq_arg1, _zzq_arg2, _zzq_arg3, _zzq_arg4, _zzq_arg5)    \
-  { volatile unsigned long long int _zzq_args[6];                 \
-    volatile unsigned long long int _zzq_result;                  \
-    _zzq_args[0] = (unsigned long long int)(_zzq_request);        \
-    _zzq_args[1] = (unsigned long long int)(_zzq_arg1);           \
-    _zzq_args[2] = (unsigned long long int)(_zzq_arg2);           \
-    _zzq_args[3] = (unsigned long long int)(_zzq_arg3);           \
-    _zzq_args[4] = (unsigned long long int)(_zzq_arg4);           \
-    _zzq_args[5] = (unsigned long long int)(_zzq_arg5);           \
+  { volatile uint64_t _zzq_args[6];                 \
+    volatile uint64_t _zzq_result;                  \
+    _zzq_args[0] = (uint64_t)(_zzq_request);        \
+    _zzq_args[1] = (uint64_t)(_zzq_arg1);           \
+    _zzq_args[2] = (uint64_t)(_zzq_arg2);           \
+    _zzq_args[3] = (uint64_t)(_zzq_arg3);           \
+    _zzq_args[4] = (uint64_t)(_zzq_arg4);           \
+    _zzq_args[5] = (uint64_t)(_zzq_arg5);           \

but this only handle 64bit, i need solulition that work both ways when i 
compile to  32bit/64bit executable

thanks,
yakir
