Question

如果我在CMake中使用clang编译器，我想为每个可能的调用添加-cc1选项（更好：仅针对某个目标）

我尝试使用

set(CMAKE_CXX_COMPILER "${CMAKE_CXX_COMPILER} -cc1")

但是这会将引用包含在引号中;因此，我的shell中不会将其识别为有效命令。

如果我使用

set(CMAKE_CXX_COMPILER ${CMAKE_CXX_COMPILER} -cc1)

然后我在clang调用和-cc1选项之间得到一个分号。这也行不通。

如何让CMake将/path/to/clang更改为/path/to/clang -cc1？

请参阅：cmake CFLAGS CXXFLAGS modification

target_compile_options(target -cc1)

对于单个目标：

private Node insert(Node newNode, String newWord){
    if(newNode == null){
        newNode = new Node(newWord);
    }
    else if (newWord.compareToIgnoreCase(newNode.getReservedWord()) < 0){
        newNode.setlChild(insert(newNode.getlChild(), newWord));

        if(depth(newNode.getlChild()) - depth(newNode.getrChild()) == 2){
            if(newWord.compareToIgnoreCase(newNode.getlChild().getReservedWord()) < 0){
                newNode = rotateWithLeftChild(newNode);
            }
            else{
                newNode = doubleWithLeftChild(newNode);
            }
        }
    }
    else if (newWord.compareToIgnoreCase(newNode.getReservedWord()) > 0){
        newNode.setrChild(insert(newNode.getrChild(), newWord));

        if(depth(newNode.getrChild()) - depth(newNode.getlChild()) == 2){
            if(newWord.compareToIgnoreCase(newNode.getrChild().getReservedWord()) > 0){
                newNode = rotateWithRightChild(newNode);
            }
            else{
                newNode = doubleWithRightChild(newNode);
            }
        }
    }
    else;

    newNode.setDepth(max(depth(newNode.getlChild()), depth(newNode.getrChild()) + 1));
    /*if(!this.getAllNodes().contains(newNode)){
        this.getAllNodes().add(newNode);
    }*/
    return newNode;
}

private Node rotateWithLeftChild(Node nodeToRotate){
    Node newNode = nodeToRotate.getlChild();
    nodeToRotate.setlChild(newNode.getrChild());
    newNode.setrChild(nodeToRotate);
    nodeToRotate.setDepth(max(depth(nodeToRotate.getlChild()), depth(nodeToRotate.getrChild()) + 1));
    newNode.setDepth(max(depth(newNode.getlChild()), nodeToRotate.getDepth() + 1));
    return newNode;
}

private Node rotateWithRightChild(Node nodeToRotate){
    Node newNode = nodeToRotate.getrChild();
    nodeToRotate.setrChild(newNode.getlChild());
    newNode.setlChild(nodeToRotate);
    nodeToRotate.setDepth(max(depth(nodeToRotate.getlChild()), depth(nodeToRotate.getrChild()) + 1));
    newNode.setDepth(max(depth(newNode.getrChild()), nodeToRotate.getDepth() + 1));
    return newNode;
}

private Node doubleWithLeftChild(Node nodeToRotate){
    nodeToRotate.setlChild(rotateWithRightChild(nodeToRotate.getlChild()));
    return rotateWithLeftChild(nodeToRotate);
}

private Node doubleWithRightChild(Node nodeToRotate){
    nodeToRotate.setrChild(rotateWithLeftChild(nodeToRotate.getrChild()));
    return rotateWithRightChild(nodeToRotate);
}

Answer 2

针对特定于clang的需求的一种解决方法是使用-Xclang编译器选项，该选项强制clang驱动程序将其后面的选项传递给clang -cc1。

例如：

target_compile_options(${target} PUBLIC "-Xclang -include-pch ${output}")

在CMake中更改编译器调用
