similar to: Metadata/DebugInfo in *.ll file

Generally, a good strategy is to look at what Clang generates for similar code and mimic that in your IR generator. -- adrian

Hi, I am new to LLVM infrastructure. Recently I am trying to set the debug info for an instruction. The main aim is to set the source line number of an instruction. Can anyone please show how to do that? I think that setMetadata method in Instruction class is to be used. But how do I create MDNode* consisting of desired source line number. Source line number can be extracted from the

Hi, I've got a problem with dovecot on an Intel Mac OSX box. Basically, I was running an older verion (0.8.?, I think), and everything was fine. Then, when I upgraded to 1.0.0 via MacPorts, I found that periodically the system gets into a state where it simply stops dealing with IMAP requests. This tends to manifest itself as Thunderbird simply stalling, not fetching any new

Hi, I was a happy user of Peter Parks' package (see http://www.chip.org/ ~ppark/Supplements/PNAS05/) and could compile it without error under Mac OS X 10.4. I then had a disk crash and had to re-install the developer tools and now I get hideous messages such as the one below. I have tried installing an earlier version of Mac OS X developer tools. No joy, Could anyone put me out of

About 2 percent of the time I use fix() to edit a function that is sitting in .RData I get the response: > fix(qss) Error in edit(name, file, editor) : problem with running editor vi when I try to close the editing session. I used to think that these were always cases where there was some syntactical error with the edited file, but this is not the case. I realize that one surefire way to

"IR" often refers to the general concept/semantics, not only the textual format in .ll files (there are 3 main forms - bitcode, textual IR, and the in-memory representation (llvm::Module, etc - constructed using IRBuilder)). A great place to start is to look at what Clang does to produce debug info - it uses IRBuilder, for instance. So you could look at how Clang uses the IRBuilder when

Before I spend some time experimenting with what might be impossible, maybe someone can just tell me (either "how" or that it's impossible). I'd like to get perdition out of my environment (mainly to have one less moving part in my architecture). I'm looking at dovecot's built-in proxying. In my setup, I don't have dedicated front-end machines. A user can connect

Thanks for the help. I thought I'd solved the problem (setting the line number information in the instruction metadata) by inserting my own function for setting line number in llvm/Support/DebugLoc.h. I have added a function setLine(unsigned) in DebugLoc class. The function simply sets the LineCol variable as needed. But there is a problem. Whenever I'm checking the line number(calling

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 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

Hello, I have an optimisation issue in an llvm IR pass - the issue being that unnecessary instructions are generated in the final assembly (with -O3). I want to create the following assembly snippet: mov dl,BYTE PTR [rsi+rdi*1] add dl,0x1 adc dl,0x0 mov BYTE PTR [rsi+rdi*1],dl however what is created is (variant #1): mov dl,BYTE PTR [rsi+rdx*1] add dl,0x1 cmp

Not sure that works.  I had that initially: auto cf = IRB.CreateICmpULT(Incr, ConstantInt::get(Int8Ty, 1)); auto carry = IRB.CreateZExt(cf, Int8Ty); Incr = IRB.CreateAdd(Incr, carry); it makes no difference to the generated assembly

Hi, I need to control IRBuilder(or manage IR building with other means) very strictly. The problem is in the realm of ConstInt/GlobalVariable handling, more precisely: LLVM converts llvm::ConstantInt values to GlobalVariable addresses ad-hoc if I store a constant in a GlobalVariable, and it appears to me, that I can do nothing about it. Consider the following, shortened code: ... 0x18: r2 =

The problem is that I want to pass only srsr which is an int. "marked" was just an example :) Thanks you!

Yes, it sounds good. I can try tomorrow. Thank you for your advice !

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 <

Hello everyone, I want to pass a set of integers using metadata but I don't know how. I have tried: the integers are in array[] *1. * LLVMContext& C = is->getContext(); Value* values[size]; for(int gy=0;gy<size;gy++){ values[gy]=ConstantInt::getSigned(Type::getInt64Ty(C),array[gy]); } *is->setMetadata("path",MDNode::get(C,values));* failes when setMetadata(),

Hi, I've been using the dovecot IMAP server for about a year now, and basically it works. But there's an annoying problem, that I can't make any subfolders. I can only make folders that are at the same level as my INBOX folder. Worse, I can't delete folders once I've created them. I'm using Debian unstable on both the server machine and my client machine. The
