+Deleting an instruction from an existing sequence of instructions that form a <a
+href="#BasicBlock"><tt>BasicBlock</tt></a> is very straightforward. First, you
+must have a pointer to the instruction that you wish to delete.  Second, you
+need to obtain the pointer to that instruction's basic block. You use the
+pointer to the basic block to get its list of instructions and then use the
+erase function to remove your instruction.<p>

+For example:<p>
+
+<pre>
+  <a href="#Instruction">Instruction</a> *I = .. ;
+  <a href="#BasicBlock">BasicBlock</a> *BB = I->getParent();
+  BB->getInstList().erase(I);
