This question appears to be off-topic. The users who voted to close gave this specific reason:
These should not be combined.
They represent different things. Look at the wikis:
infrared doesn't have a wiki as far as I know. However, they seem to be different things. Sure, it is confusing. There's only 57 ir questions, so it might be worth it to sort through all of those and see if any of them are infrared. Then, the tag ir should be renamed to "llvm-ir" or something similar. However, they are not the same thing.
