CreateGlobalStringPtr 내가 CreateGlobalStringPtr 메인

Question

다음 충돌에 대한 방법 + 기본 블록을 생성하지 않는 경우 충돌 :

#include "llvm/Support/DataTypes.h" 
#include "llvm/LLVMContext.h" 
#include "llvm/Module.h" 
#include "llvm/Constants.h" 
#include "llvm/Function.h" 
#include "llvm/BasicBlock.h" 
#include "llvm/ExecutionEngine/ExecutionEngine.h" 
#include "llvm/ExecutionEngine/GenericValue.h" 
#include "llvm/Support/IRBuilder.h" 

#include <vector> 
#include <cstdio> 
#include <string> 

int main() 
{ 
    llvm::LLVMContext & context = llvm::getGlobalContext(); 
    llvm::Module *module = new llvm::Module("asdf", context); 
    llvm::IRBuilder<> builder(context); 
    llvm::Value *helloWorld = builder.CreateGlobalStringPtr("hello world!\n"); // crash here 
} 

을 그리고이 하나가 아닌 여기에 무슨 일이 일어나고 있는지 어떤 생각을 수행합니다

#include "llvm/Support/DataTypes.h" 
#include "llvm/LLVMContext.h" 
#include "llvm/Module.h" 
#include "llvm/Constants.h" 
#include "llvm/Function.h" 
#include "llvm/BasicBlock.h" 
#include "llvm/ExecutionEngine/ExecutionEngine.h" 
#include "llvm/ExecutionEngine/GenericValue.h" 
#include "llvm/Support/IRBuilder.h" 

#include <vector> 
#include <cstdio> 
#include <string> 

int main() 
{ 
    llvm::LLVMContext & context = llvm::getGlobalContext(); 
    llvm::Module *module = new llvm::Module("asdf", context); 
    llvm::IRBuilder<> builder(context); 

    // Added extra 
    llvm::FunctionType *funcType = llvm::FunctionType::get(builder.getVoidTy(), false); 
    llvm::Function *mainFunc = llvm::Function::Create(funcType, llvm::Function::ExternalLinkage, "main", module); 
    llvm::BasicBlock *entry = llvm::BasicBlock::Create(context, "entry", mainFunc); 
    builder.SetInsertPoint(entry); 

    llvm::Value *helloWorld = builder.CreateGlobalStringPtr("hello world!\n"); 
} 

을 메인 루틴과 엔트리 포인트를 만드는 것이 어떻게 충돌을 제거 할 수 있는지 확신 할 수 없습니다. 그들은 무관하다고 생각했습니다. 여기 내 옵션 g ++ 컴파일을 위해 다음과 같습니다 CreateGlobalStringPtr이 빌더에 명령어를 삽입하는 기능과 기본 블록을 필요로 당신의 문자열에 GEP를 만드는
