similar to: Call printf with new args

Hi, I have problem with IRBuilderBase::InsertPointGuard class that simply does not work in the release build of my project. The class does not restore the IRBuilder's insert point correctly when NDEBUG macro is set. It happens on OSX system only, trunk version of the LLVM built with brew. I suspect it is the ABI problem. InsertPointGuard uses AssertingVT for debug builds. LLDB gets confused

Thanks a lot Nick -march=cpp was very helpful. But I still have a small problem, I am trying to insert a printf in a transformation pass. So when the original program already has a printf, on executing the transformation pass, it tries to create function "printf1" instead of "printf" Am I missing something here? Thanks again!

Hi all, consider the following function from Core.cpp in LLVM 9.0.0: LLVMValueRef LLVMBuildMalloc(LLVMBuilderRef B, LLVMTypeRef Ty, const char *Name) { Type* ITy = Type::getInt32Ty(unwrap(B)->GetInsertBlock()->getContext()); Constant* AllocSize = ConstantExpr::getSizeOf(unwrap(Ty)); AllocSize = ConstantExpr::getTruncOrBitCast(AllocSize, ITy);

This addition converts strlen() calls to strnlen() when the result is compared to a constant. For example, the following: strlen(s) < 5 Becomes: strnlen(s, 5) < 5 That way, we don't have to walk through the entire string. There is the added overhead of maintaining a counter when using strnlen(), but I thought I'd start with the general case. It may make sense to only use this

Hi, I was compiling libc++ with a recent TOT (248571) and when I got to the ARMv6, I got a code generation error in memory.cpp: fatal error: error in backend: Cannot select: intrinsic %llvm.arm.clrex ecc: error: clang frontend command failed with exit code 70 (use -v to see invocation) clang version 3.8.0 (trunk) It looks as if the newly added emitAtomicCmpXchgNoStoreLLBalance() function is

Hi Everyone, I want to generate IR for the following C code printf("Hello World!"); To insert a printf call in the IR, I use Function* myPrint = M.getFunction("printf"); to get the function from my symbol table. Once I have the function to make a call to this function I use CallInst::Create(myPrint, args.begin(), args.end(),"", B); But I am not being able to

Hi, I am trying to use some LLVM API in my C++ code, and I end up getting linker errors. I am working on Apple MacOSX Lion. Using g++ for the compile. It is the CreateGlobalStringPtr which is throwing the error. This is LLVM 3.0. Here's the codeI am trying to use some LLVM API in my C++ code, and I end up getting linker errors.

Hello LLVMDev List, It's my first time sending a message to the List - I have been working on a tool for my research project using LLVM. Thanks for your awesome work! I have come across some bytecode like the following with an GetElementPtr instruction in brackets: Bytecode:%3 = call i32 @_Z4funcPKc(i8* getelementptr inbounds ([5 x i8]* @.str2, i32 0, i32 0)) C++ code:func("bleh");

Probably your g++ compiles x86_64 binary by default, but i686 dylib is supplied?

Cool, that's certainly easy enough. :) Thanks, Albert -- Dr. Albert Gr"af Dept. of Music-Informatics, University

Now I've run into another issue: The ConstantArray::get() method for constructing a string constant from a char* seems to be gone. Is there a replacement for that somewhere? BTW, this isn't mentioned in the release notes yet. -- Dr. Albert Gr"af Dept. of Music-Informatics, University of Mainz, Germany Email: Dr.Graef at t-online.de, ag at muwiinfa.geschichte.uni-mainz.de WWW:

Greetings, Lang and other JITters, Last week I moved our Orc v2-based app from top-of-tree to the new 11.x branch, and it no longer handles C++ code containing OpenMP directives correctly. More specifically, if I JIT compile a function containing OpenMP parallel/for pragmas, using a release version of LLVM, the code compiles and seems to work, but if I try to write the module's bitcode to

Hi Geoff, Nothing in that backtrace leaps out at me. Based on the stack trace and description my first guess would be a clang misconfiguration rather than a JIT bug. How is that clang invocation being made? Is it from inside a callback from ORC, or is it before you add your module to the JIT? -- Lang.
