zouquiong,
I think that the error with types. Check counter-access for for edge profile
as example:
uint32* ptr = key == 0 ? edgeProfile->getEntryCounter() :
edgeProfile->getCounter(key );
   assert( ptr != NULL /*&& *ptr == 0 if compilation is locked*/);
   Opnd* baseOpnd = irManager.newImmOpnd(typeManager.getUnmanagedPtrType(
typeManager.getUIntPtrType()), (POINTER_SIZE_INT)ptr);
   Opnd* memOpnd = irManager.newMemOpnd(typeManager.getUIntPtrType(),
MemOpndKind_Heap, baseOpnd, NULL, NULL, NULL);
   const Mnemonic mn = Mnemonic_ADD;
   Inst* inst = irManager.newInst(mn, memOpnd,  irManager.newImmOpnd(
typeManager.getUInt32Type(), 1));

The address of the counter has Pointer but but UInt32 type.

I add the following expression in InstCodeSelector::addElemIndex():

Opnd* current_buffer = irManager.newImmOpnd(typeManager.getInt32Type(),
(unsigned)&current_obj_acc_record_pointer);

Opnd * Ip_Opnd = irManager.newMemOpndAutoKind
(typeManager.getPrimitiveType(Type::UInt32),
current_buffer, irManager.newImmOpnd(typeManager.getInt32Type(), 8));

copyOpnd(Ip_Opnd, irManager.newImmOpnd(typeManager.getInt32Type(),
0x19820514));

It seems that the constraints of the Opnds are wrong. Is it?

current_obj_acc_record_pointer points to a buffer of type obj_acc_record

typedef struct {
           uint32 base;
           uint32 offset;
           uint32 ip;
           uint32 other_info;
}obj_acc_record;
