<pre>Reported in <a href="https://www.viva64.com/en/b/0629/">https://www.viva64.com/en/b/0629/</a>
static Value *optimizeDoubleFP(CallInst *CI, IRBuilder<> &B,
bool isBinary, bool isPrecise = false) {
....
Function *CalleeFn = CI->getCalledFunction();
StringRef CalleeNm = CalleeFn->getName(); // <=
AttributeList CalleeAt = CalleeFn->getAttributes();
if (CalleeFn && !CalleeFn->isIntrinsic()) { // <=
....
}
Theres a number of places later on as well that assume CalleeFn is not null.
Last touched by @evandro at rL338905
Do we actually need the if(CalleeFn) test - the previous version didn't check
at all.</pre>
