search for: stringstreams

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

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!

However, it would be possible to use a stringstream for this. I think

So by now you have already seen this, but just in case you have not: ============= Note that using the other stream headers (<sstream> for example) is not problematic in this regard — just <iostream>. However, raw_ostream provides various APIs that are better performing for almost every use than std::ostream style APIs. Therefore new code should always use raw_ostream for writing, or

I need to generate variables like status1, status2, status3, ...... request1, request2, request3, ...... this is my code, other unrelated detail are eliminated. static int varNum; static const char *getVarNum() { ++varNum; std::stringstream ss; ss << varNum; std::string *varname = new std::string(ss.str()); return varname->c_str(); } const char *VarNum = getVarNum(); Twine *x1 = new

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?

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 =

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

Hi, I think you may try to use llvm::Twine(int). For example, to convert 30 to string, you can use: Twine(30).str() To convert the string back to integer, you can try the StringRef::getAsInteger(unsigned, APInt &). For example: APInt i; str.getAsInteger(/*radix=*/ 10, /*output=*/ i); Sincerely, Logan On Thu, May 2, 2013 at 9:53 PM, Alexandru Ionut Diaconescu <

Hi LLVM devs, I work on a pass that creates multiple versions of a code region and switches between them. The decision about the version to be selected is taken by an external runtime system. I insert callbacks to this system in my code to pass the control of the execution. All callbacks are written in inline assembly, in macros. The problem comes when I need to send some information from

According to documentation Twines should be used only for temporary values and not stored, so allocating the in heap sounds wrong. I think all you need here is static int varNum; ++varNum; Instruction *sstatusInst = new AllocaInst(StatusTy, Twine("status") + Twine(varNum), entry_inst); Instruction *sreqInst = new AllocaInst(ReqTy, Twine("request") + Twine(varNum),

Hi, I am trying to replace a c-style function with another function with same signature. Consider the following code: std::stringstream main_c; main_c <<"#include <stdio.h>\n" <<"extern \"C\" { \n" <<"int print1()\n" <<"{\n" <<" printf(\"Inside

Yes, in general you should never be naming Twine directly, except in the case where you need to make a Twine for an integer. All other uses should be considered poor style, as

I think the better solution should be: LLVMContext& C = is->getContext(); Value *values[] = { ConstantInt::getSigned(Type::getInt64Ty(C), *scsr*), MDString::get(C, *"path"*) }; lnstr.setMetadata(*"your_analysis_name"*, MDNode::get(C, values)); So that you can take advantage of the type system of LLVM bitcode, and don't have to cast the integers from/to strings
