[LLVMdev] LLVM-Kaleidoscope tutorial

[Remy Demarest]

Good morning everyone,

It seems the LLVM tutorial is not up to date anymore and doesn't  
compile as is...

The function makeLLVMModule() function doesn't compile at all. Here is  
a fix:

Module *makeLLVMModule()
{
     // Caches the global context to share it with new Module() and  
IntegerType::get() calls
     LLVMContext &context = getGlobalContext();

     // Module Construction
     Module *mod = new Module("test", context);

     Constant *c = mod->getOrInsertFunction("mul_add",
                                            // IntegerType::get 
(context, 32) instead of IntegerType::get(32)
                                            IntegerType::get(context,  
32), // Return type
                                            IntegerType::get(context,  
32), // Arguments
                                            IntegerType::get(context,  
32),
                                            IntegerType::get(context,  
32),
                                             
NULL                           // Varargs terminated with NULL
                                            );

     Function* mul_add = cast<Function>(c);
     mul_add->setCallingConv(CallingConv::C);
     Function::arg_iterator args = mul_add->arg_begin();
     Value *x = args++;
     x->setName("x");
     Value *y = args++;
     y->setName("y");
     Value *z = args++;
     z->setName("z");
     BasicBlock *block = BasicBlock::Create(getGlobalContext(),  
"entry", mul_add);
     IRBuilder<> builder(block);
     Value *tmp = builder.CreateBinOp(Instruction::Mul,
                                      x, y, "tmp");
     Value *tmp2 = builder.CreateBinOp(Instruction::Add,
                                       tmp, z, "tmp2");

     builder.CreateRet(tmp2);

     return mod;
}
