我想要为一个新的目标构建一个编译器，然后选择llvm。据我所知，我可以使用clang项目作为前端，将llvm用作后端。我可以从llc (llvm的一部分)中获取.o文件。现在我需要将它们都链接到可执行文件中。我试过使用lld项目，但是编译失败了，错误如下：

Desktop/llvm_project/llvm/lib/Target/ARM/ARMISelLowering.cpp: In member function ‘llvm::Instruction* llvm::ARMTargetLowering::makeDMB(llvm::IRBuilder<>&, llvm::ARM_MB::MemBOpt) const’:
Desktop/llvm_project/llvm/lib/Target/ARM/ARMISelLowering.cpp:11000:73: error: could not convert ‘{(& Builder)->llvm::IRBuilder<>::<anonymous>.llvm::IRBuilderBase::getInt32(15u), (& Builder)->llvm::IRBuilder<>::<anonymous>.llvm::IRBuilderBase::getInt32(0u), (& Builder)->llvm::IRBuilder<>::<anonymous>.llvm::IRBuilderBase::getInt32(0u), (& Builder)->llvm::IRBuilder<>::<anonymous>.llvm::IRBuilderBase::getInt32(7u), (& Builder)->llvm::IRBuilder<>::<anonymous>.llvm::IRBuilderBase::getInt32(10u), (& Builder)->llvm::IRBuilder<>::<anonymous>.llvm::IRBuilderBase::getInt32(5u)}’ from ‘<brace-enclosed initializer list>’ to ‘llvm::ArrayRef<llvm::Value*>’
                                Builder.getInt32(10), Builder.getInt32(5)};
                                                                         ^
make[2]: *** [lib/Target/ARM/CMakeFiles/LLVMARMCodeGen.dir/ARMISelLowering.cpp.o] Error 1
make[1]: *** [lib/Target/ARM/CMakeFiles/LLVMARMCodeGen.dir/all] Error 2
make: *** [all] Error 2

所以我有几个问题，因为我想我遗漏了一些东西：

如果我没有新目标的二进制文件，我应该如何使用llvm项目？-他们创建伟大的project...but，而没有最后一块实际创建运行的文件?！我应该用什么做链接器？
有人遇到这个lld构建错误并解决了吗？
