   Hi,   
      
   [shameless plug:]   
   Here's a link to the slides of a talk I have last January on undefined   
   behavior (UB) for compiler IRs:   
      
   http://web.ist.utl.pt/nuno.lopes/pres/ub-vmcai19.pptx   
      
   The slides have a bunch of examples showing why UB is sometimes useful for   
   compilers, when it is detrimental, or why it's basically impossible to make   
   certain languages fully specified.
