Thank you. Is it possible to determine the liveout of the operands (see example bellow) ? %5 = add i32 %4, %3 For '%5': i can simply use " i->isUsedOutsideOfBlock() " For '%3' and '%4' : this is the question ... >From your answer, is it possible to determine *which* value is liveout ( in binary instruction)?

By definition, operands are live out if they're used in any block that's reachable from the block containing the instruction. Barring a few special cases we've already covered, the easiest way I know to com...

If the value is created within the basic block in question, and the block doesn't loop to itself, then you can just iterate through the uses and note if the use is an instruction in a different

Hi, How can i know, if a value have uses outside of the current basic block (liveout), without iterating through all the basic block ?
