search for: itoa

I apologize if this is the wrong list. I'm writing a language and outputting llvm-ir instead of using the c api. I looked at clang's output a few times but I'm a little unsure what to do in this case As an example I have a function called itoa which takes an int and returns a string. Strings in my language has 2 fields, the pointer and byte length. On a 64bit machine it'd be returning a 64bit pointer and 64bit int value. My question is HOW should I do this if I want to generate fast code? And a follow up is should I do it that way if...

Hello everyone, I have an integer and I want to convert it to StringRef in order to set metadata. setMetadata->(StringRef, MDNode*); It is there a native LLVM way to do it? 1. In the llvm::APSInt Class is toString() method, which seems it is not for this purpose 2. itoa and string are not part of LLVM 3. stringstream is not part of LLVM 4. to_string is not part of LLVM 5. any casting method? Also, I would like to get the metadata and convert it back to integer. Thank you ! -------------- next part -------------- An HTML attachment was scrubbed... URL: <http:/...
