optimisation issue in an llvm IR pass
...being generated?
For me its the same result on LLVM 6.0 and 7.
Alternatively
add BYTE PTR [rsi+rdi*1],0x1

would work as well.
Thank you very much!

-> Below now is the full llvm IR pass code
// vvv same code before both variants
LoadInst *PrevLoc = IRB.CreateLoad(AFLPrevLoc);
PrevLoc->setMetadata(M.getMDKindID("nosanitize"), MDNode::get(C, None));
Value *PrevLocCasted = IRB.CreateZExt(PrevLoc, IRB.getInt32Ty());
LoadInst *MapPtr = IRB.CreateLoad(AFLMapPtr);
MapPtr->setMetadata(M.getMDKindID("nosanitize"), MDNode:...
