Hi, the docs for InstVisitor say that if RetType != void, one has to override visitInstruction. What is the reason for that? It's valid to define visitInstruction like that: RetTy visitInstruction(Instruction &I) { return RetTy(); } so assuming RetTy has a sensible default constructor, user won't need to override visitInstruction. Note that the above will work when RetTy ==

Dear All I'm making an instrumentation pass. The pass is supposed to modify the given IR in a specefic way. One of the required modifications is to insert a call to a function at a specific location. This is the signature of the called function: void myclass::foo(Function *f, BasicBlock* b) This function's prototype is in an foofile.h file in include/llvm And the function

Hello Pedro, As others have said we're assuming that you're using Clang as the frontend, the MSP430TargetInfo class inside lib/Basic/Targets.cpp (clang codebase) set ints to be 16 bits wide, so you should get 16bit mults straight away without promotion. But anyways for 8bit multiplicantions you can do the following to bypass argument promotion: 1) go to the lib/CodeGen/TargetInfo.cpp

Following is my query: 1. Removing Inf from one column of dataframe. 2. out of 10 available dates, count how many times a security is present. (repeat for each security) 3. Out of dates, the security is present, I want to read latest status of market cap. 4. Change in market cap represent by 0/1 so even if market cap status changed once, take value 1. 5. create output file containing some already

Hi LLVM-ers, I am trying to get a return type of a function(from bitcode file) with LLVM-C API, but there seems no appropriate API to do that. I've tried to do that with following code, ---- LLVMModuleRef M; LLVMMemoryBufferRef MemBuf; LLVMValueRef F; // Function LLVMTypeRef RetTy; char *ErrStr; // // -- Load shader module //

I want to add command line (shell) like statement to C is it possible to implement this syntax by clang and llvm? The syntax is like func arg1 arg2 ... argn; and define func like void func( int arg1, int arg2, ..., int argn) { ...} Charlie -------------- next part -------------- An HTML attachment was scrubbed...

Well, I updated to cmake 2.8.12.2 but the result of changing that COMPILE_FLAGS to COMPILE_OPTIONS is that quotes are applied incorrectly: quotes are added surrounding the entire set of flags rather than around each individual item in the list. Obviously the build doesn't work (with the compiler looking for files named " -m64 ... ") but checking the relevant build command in

I have a pointer to a function that I need to invoke without going through llvm::Module::getOrInsertFunction. This example does not work: static int add(int x, int y); llvm::Value *one, *two; llvm::Constant* addfn = llvm::ConstantInt::get(JB->getIntPtrTy(DataLayout), (intptr_t)add); llvm::Type* args[] = { Int32Ty, Int32Ty }; llvm::FunctionType* ftype = llvm::FunctionType::get(Int32Ty,

Hi Joshua, I have a function foo and I want to insert exit(0) at the end of foo. The problem is M.getFunction returns null, which is understandable. I am not sure what to do. Below is the code snippet. void foo(int argc, char* argv[]) { printf("hello world\n"); exit(0); //***I want to insert this exit } My llvm code snippet is vector<const Type *> params =

Hi, I found some suspicious code in X86TargetLowering::getRegClassForInlineAsmConstraint, but I don't know if it's a bug or my poor understanding of what the code does. This is the code in question: (lib/Target/X86/X86ISelLowering.cpp:5064) if (VT == MVT::i32) return make_vector<unsigned>(X86::EAX, X86::EDX, X86::ECX, X86::EBX, 0); else if (VT == MVT::i16) return

Hi all, Sorry for the inconvenient about the previous post. The files were not attached. So I put them here again. I am a newbie in LLVM and I am trying to replace the function like: old function || new function ============================== ========= int haha(int a) { int haha(int a, char* ID) { ===> }

How do you handle this during codegen? One problem is avoid stack changes (like spills). Another is coordinating things that are using allocas and those that are not but end up in the stack. Consider void foo(int arg1, int arg2, int arg3, ....CXXTypeWithCopyConstructor argn, int argp1...) You will need an alloca for argn, but the ABI also requires it to be next to the plain integers that
