Hello everyone,
As i saw that is not possible to add metadata to a basic block, it is possible
to add more metadata fields to an instruction?
I saw that in the definition of setMetadata(), it updates/replaces the metadata
if already existent. As far as I understand, updates=replaces, not updates OR
replaces. I add metadata using :
LLVMContext& C = instr->getContext();
MDNode* N = MDNode::get(C, MDString::get(C, "var"));
instr->setMetadata("varvar", N);
Thank you in advance !
