Hi, I need to convert an integer into a string. I would normally do that in C++ by using the StringStream class, but the LLVM coding standards discourage using that class. The same coding standards suggest to use llvm:StringStream instead, but I cannot find that class anywhere; furthermore, the header file where it was supposed to be (according to the coding standards) doesn't even exist. Is there any LLVM-native way to do that? What I want to do is to replicate a function several times and append a sequence number to each replica's name. Thanks ahead, Pablo

Instead I offer information to the llvm community: C++ 11 offers these new functions in <string>: string to_string(int val); string to_string(unsigned val); string to_string(long val); string to_string(unsigned long val); string to_string(long long val); string to_string(unsigned long long val); string to_string(float val); string to_string(double val); string to_string(long double val); The only place I know of in current use where they are not implemented is Apple's v4.2 libstdc++. I believe they've been in gcc and VC++ for several years. They are also in libc++. Howard
Hi Pablo, Can you provide a link to the document containing a reference to llvm::StringStream? I've looked in both the llvm coding standards, and llvm programming manual for versions: ToT (3.0), 2.9 (which seems to be the same as ToT), and 2.8. Obviously my search is missing something.

Try utostr_32/utostr/itostr defined in the llvm/ADT/StringExtras.h.

I believe they've been in gcc and VC++ for several years. They are also in libc++.VC++ only has had them since VS2010, and they're quite broken: too few overloads lead to ambiguity errors when doing very reasonable things. Sebastian
http://llvm.org/releases/2.0/docs/CodingStandards.html I just realized that the target version is LLVM 2.0, so most likely the llvm::StringStream is deprecated by now. Thanks for your response!

https://bitbucket.org/carli/gwscript/src/tip/libs/strings.ll
where string is defined with
%.string = type {i32, i32, i32, [0 x i8]}
(reference counter, length, max-length of the buffer, content)
you can modify and adapt the sources as you want.
