<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I suspect you have some confusion as to how LLVM works.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">In LLVM terms, an Instruction is essentially an opcode, some opcode-specific flags, and a list of Value operands that it uses. Instructions are themselves Values,
so that means that to use the result of an instruction, you pass the Instruction itself to the method that accepts a Value. There is no “destination” of an Instruction in structural terms.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">In the textual format of LLVM, Instructions are represented by printing out %<name> = <textual representation of an instruction>, and subsequent uses of the instruction
are referred to in the %<name> format. Names of instructions (and a few other values) must be unique, with the exception of the empty string. The %<name> representation for an empty name string is replaced with a unique autoincrementing integer that is not
readily accessible via the APIs (you need to go through the ModuleSlotTracker to get to it). If you’re really trying to get that exact string for an instruction, you are generally doing something wrong and there is an easier way to go about whatever it is
you want to do.<o:p></o:p></span></p>
