• by Jin [Thu, 05 May 2016 17:04:35 -0400] rev 3
• TemplateTable::fast_xaccess(): fix unaligned lhu
  
  BCP and offset may both be unaligned.
  Two LBU are required.
  
  public class List {
  public List next;
  
  public void insert() {
  List p = new List();
  p.next = this.next;
  }
  
  public static void main(String[] args) throws Exception {
  List th = new List();
  while(true)
  th.insert();
  }
  }
  
  Effect:
  - -Xint: 0 unaligned access

• TemplateTable::_new(): fix unaligned lw
  
  
  InstanceKlass::init_state is defiend as "u2" and is assigned to 2-byte
  boundary. Its offset is 0x16a.
  Such field should be accessed with LHU.
  
  public class List {
  public static void main(String[] args) {
  List th;
  while(true)
  th = new List();
  }
  }
  
  
  Effect:
  * -Xmixed / -Xint: no unaligned instructions
