Hi, guys. I'm a newbie to LLVM and have a very simple question. Which instructions should I use (in terms of IRBuilder calls) to allocate an array of bytes in stack (alloca?), then to work with it (from a given offset) as with integer (bitcast?). I mean something like that: unsigned char var[8]; unsigned int offset = 3; int val = *(int*)(&var+offset); /* read */ *(int*)(&var+offset)

...ntially what I try to generate: void add(float z[4], float x[4], float y[4]) { z[0] = x[0] + y[0]; z[1] = x[1] + y[1]; z[2] = x[2] + y[2]; z[3] = x[3] + y[3]; } And here's part of the output from the online demo: LoadInst* float_tmp2 = new LoadInst(ptr_x, "tmp2", false, label_entry); LoadInst* float_tmp5 = new LoadInst(ptr_y, "tmp5", false, label_entry); BinaryOperator* float_tmp6 = BinaryOperator::create(Instruction::Add, float_tmp2, float_tmp5, "tmp6", label_entry); StoreInst* void_20 = new StoreInst(float_tmp6, ptr_z, false, label_entry); GetElementPtrI...

...nderstand how to use. So, the java code is: int[] ai; .... ai = new int[1]; I am using LLVM API in this way: //I create a pointer of Opaque type, because I don't know yet the array size! OpaqueType* ot = OpaqueType::get(); AllocaInst* ptr_addrOP = new AllocaInst(ot, "ai_addr", label_entry); //I create pointer of Array type when it is initialized ArrayType* art = ArrayType::get(Type::IntTy, 1); AllocaInst* ptr_addrAr = new AllocaInst(art, "ai_addr", label_entry); //I try to make concrete the abstract pointer ((PointerType*)ptr_addrOP -> getType()) -> typeBecameCon...

...the times a wrong bc file as output, because when i try to execute it with lli it says to me invalid signature. 2 - for (Module::iterator a=M.begin(),b=M.end();a!=b;++a) { for (Function::iterator i = a->begin(), e = a->end(); i != e; ++i){ new StoreInst(const_int32_12, gvar_int32_x, false, label_entry); // normally label entry would be the end of the basic bloc i } } what would be the value of label entry to make the instruction inserted at the end of the basic bloc when i have tried this: Instruction* label_entry = i->begin(); new StoreInst(const_int32_12, gvar_int32_x, false, label_entry);...

...to use llvm to translate and generate the native code in parallel with multi-thread. But some various bugs will be triggered. We run the following code in multithread environment: ################## BasicBlock::Create(_CTX(), "dispatch", cpu->cur_func, 0); BranchInst::Create(bb_start, label_entry); cpu->exec_engine->getPointerToFunction ##################3 And cpu variable is stored for every thread.
