search for: stringstream

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...

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.

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!

I see: It needs to be written in order to compute the offsets. However, it would be possible to use a stringstream for this. I think the best thing to do is to write the final archive to a temporary file, and then move it into place. This has the advantage that if something goes wrong the original archive will not be corrupted. Additionally, all the members of the current archive object instance stay valid...

...ne, 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...

Hello, I'm working on an LLVM IR pass and would like to insert comments into the generated .bc file during the pass. I've been having trouble finding documentation for this process, and was wondering if there is a simple way to do it. At the moment, I have a stringstream whose .str() I'd like to stick in this generated file every once in a while. Thanks, Griffin Wright

Hello All, A simple question. I get some return from the R in my C++ program (via Rcpp package). The result come, as SEXP and it should be a simple numeric variable. How to convert it to double? The code, what i use: stringstream ss; ss << "p <- predict(fit_ar11, n.ahead = 2, doplot=FALSE);" << "p$pred[1]"; SEXP ans; int iRet = R.parseEval(ss.str().c_str()); if (iRet == 0 && ans != NULL) { // ??? } Cheers, Dima [[alternative HTML version deleted]]

I did some computation through llvm pass, and store those computed values on string. eg. :- stringstream lhs; lhs << instr->getOperand(1); // 'instr' is some instruction string lhsvar=lhs.str(); Now I want to pass this 'lhsvar' to the external function, so how can i do this??? This is just the part of a code to make you understand. if you say I can even provide the link t...

...parameter the address of this variable, such that the runtime system can put the value it computes in this address, at runtime. (Similar to sending a parameter by reference. ) If I send the address of the Value* lim as a param to the macro, it puts the hardcoded address (as expected). std::stringstream out; out.str(std::string()); out << &lim; InlineAsm* IA = InlineAsm::get(asmFuncTy, "camus_macro_decision" + out.str() , "=r", true); CallInst* cmp = CallInst::Create(IA, ...); creates the call: camus_macro_decision 0x7fffdf3172f0 I tried also by creatin...
