[LLVMdev] Value liveout (uses)
...ut iterating through all the basic block ?
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 block:
bool isLiveOut(Instruction* I) {
BasicBlock* I_BB = I->getParent():
for (Value::use_iterator ui = I->use_begin(), ue = I->use_end(); ui !
= ue; ++ui)
if (cast<Instruction>(ui)->getParent() != I_BB)
return true;
}
}
If the value is created within the block but the block loops to
itself, you can get away with a very slig...
