如何在 cpp 中抑制 'missing termination character' 警告？
How to suppress a 'missing termination character' warning in cpp?
我正在尝试使用 cpp（ANSI-C 预处理器）来预处理一些非 ANSI-C 文件。
这些文件包含 PicoBlaze 语法中的汇编指令。 PicoBlaze 使用 'd 来注释文字的基数。我想用 cpp 预处理我的文件。
我得到了几个：
<stdin>:228:163: warning: missing terminating ' character [enabled by default]
<stdin>:257:98: warning: missing terminating ' character [enabled by default]
...
警告。如何在 cpp 中禁用 '（或所有字符）的终止字符检查？
这是我的命令行调用：
cpp.exe -E main_Page0.psm
我想我自己找到了解决方案，但我仍然愿意接受其他建议。
解决方案 1)
-w 禁用所有警告 -> 不满意
Suppress all warnings, including those which GNU CPP issues by default.
GCC Manual (v4.9.2) -> page 158
解决方案 2)
-x assembler-with-cpp 将 cpp 的源语言设置为汇编。
如果文件扩展名未知（等于 -x c），则默认语言为 ANSI-C。
Specify the source language: C, C++, Objective-C, or assembly. This has nothing to do with standards conformance or extensions; it merely selects which
base syntax to expect. If you give none of these options, cpp will deduce the
language from the extension of the source file: ‘.c’, ‘.cc’, ‘.m’, or ‘.S’. Some
other common extensions for C++ and assembly are also recognized. If cpp does
not recognize the extension, it will treat the file as C; this is the most generic mode.
