使用 clang 格式更改宏中使用的行延续符 （'\“） 的位置

问：

我有使用宏的代码，其中一些很长。 在运行 clang-format 之前，一个示例如下所示：

    #define assertionTriggersExit { \
      std::cout.flush(); \
      std::cerr.flush(); \
      tarch::logging::Log::flushBeforeAssertion(); \
      assert(false); \
      exit(ASSERTION_EXIT_CODE); \
    }

在 clang-format 之后（滚动查看 \ chars）：

#define assertionTriggersExit                                                                                          \
  {                                                                                                                    \
    std::cout.flush();                                                                                                 \
    std::cerr.flush();                                                                                                 \
    tarch::logging::Log::flushBeforeAssertion();                                                                       \
    assert(false);                                                                                                     \
    exit(ASSERTION_EXIT_CODE);                                                                                         \
  }

行延续符为 120 个字符，这是列限制。我希望 clang-format 不要更改 \ 字符的位置（一般来说，我希望它们要么保持不变并保持原来的样子，要么它们距离最后一个不是 ' ' 的字符有 1-2 个空格。我找不到防止它的选项（或选项组合），有人可以帮忙吗？

我正在为代码库编写一个基于 llvm 样式的新 clang 格式文件。我目前拥有的样式文件如下：
