長巨集可能難以讀取。 Visual Studio 現在可以展開 C 和 C++ 巨集。 您可以在剪貼簿上取得已展開巨集外觀的複本、將巨集內嵌取代為其展開,並逐步展開巨集,以查看其在每個展開階段的外觀。 在本文中,您會試驗所有這些功能。 必要條件 Visual Studio 17.5 版或更新版本 ...
事实几乎如此——二进制文件包含了 CPU 执行的所有代码,但代码分散在多个文件中,方式非常复杂。链接是一个简化事物并使机器代码整洁、易于消费的过程。 快速查看命令列表会让你知道 CMake 并没有提供很多与链接相关的命令。承认,target_link_libraries()是唯一一个实际配置这一步骤的命令。那么为什么要用一整章来讲述...

-fast acts like a macro expansion on the command line. Therefore, you can override the optimization level and code generation option aspects by following -fast with the desired optimization level or code generation option. Compiling with the -fast -xO4 pair is like compiling with the -xO2 -...
Sed strips __tmp suffix from parameter names used to avoid macro name conflicts. Grep strips ); to remove redundant forward declarations and sed then adds ; to make each line a valid C prototype. The above is not guaranteed to always work as output may change, but it should go a long ...
