similar to: [LLVMdev] Integer to string

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 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

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

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?

I applied the patch to the trunk version successfully, although I get an error in between: 1 out of 1 hunk FAILED -- saving rejects to file lib/Transforms/IPO/CMakeLists.txt.rej Can I ignore the error? The patch exits normally except for that error. Also, I tried to apply the patch to the LLVM 3.0 but does not work at all. Is the trunk version the only one where the patch can be applied?

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 <

The patch exits normally except for that error. The attached patch should apply cleanly. Thanks for the feedback,

Hi, Apologies for the very late response. We have manually tried the idea with a very simple Fibonacci sequence code. While being very very simple, the recursion cannot be handled by TRE. Because there are two recursive callsites, it also needs to keep some sort of state across iterations of the "while(stack not empty)" loop. We get between 2.5 and 8x slowdowns depending on which

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

How can I install the patch? Any step-by-step guide?

Hi Hal, > As we had briefly mentioned on IRC, one way of forming this 'stack', and its associated 'cnt' variable, is to use dynamic stack allocation. I hadn't really reached a decision on the mechanics yet. However, your suggestion while it can work within the current abilities of the IR, has the disadvantage that it is using an extra stack slot for the link pointer. I

Hi all, I'm starting a new project and I'm having some trouble with the LLVM configure+Makefile system. When I type "./configure" in the sample project, it seems to work. However, after going down to the autoconf dir and typing "./AutoRegen.sh", when I go back to the project main dir and type "./configure" again, I get the following error: configure:

Hi all, I'm having trouble when trying to reuse some functions that use Boost::Exception into my LLVM-based application. As far as I know, LLVM turns off Exception handling (apparently for performance reasons), so I get the following link-time error in a few places: "undefined reference to `boost::throw_exception(std::exception const&)" When I compile the external code from
