Question

是否可以禁用外部库的MISRA检查？我已经尝试过了，但是似乎不起作用（此标头使用C ++样式注释和不兼容的@标记）。

#pragma ghs startnomisra
#include <qcarcam.h>
#pragma ghs endnomisra

更新10/4/18：最小示例

#pragma ghs startnomisra
#include <INTEGRITY.h>
#include <unistd.h>
#include <stdlib.h>
#pragma ghs endnomisra


int main(void)
{
    const char* msg = "Hello world";
    write(1, msg, strlen(msg));
    Exit(0);
}

编译器输出：AFAIU这些行与#pragmas所包含的内容有关

解决方案 #pragma diag_suppress=tag[,tag,...]也可用于禁止来自MISRA C检查器的消息。

为避免必须为每个#include编写一列MISRA C标签，可以使用以下两个宏：

#define MISRAC_DISABLE _Pragma ("diag_suppress= \

要禁用头文件的MISRA C检查，您可以编写...

MISRAC_DISABLE
#include "myincludes.h"
MISRAC_ENABLE

有关更多详细信息，请参见https://www.iar.com/support/tech-notes/compiler/disable-misra-c-for-include-files/

Answer 2

您可以通过将--misra_2004=none（或--misra_2012=none）添加到相关项目文件中来禁用每个库单元或每个文件的MISRA检查，例如：

图书馆：

#!gbuild
[Library]
    -object_dir=$__OUT_DIR
    -o $__OUT_DIR/lib/libfoo.a
    --misra_2004=none

程序中的单个文件：

#!gbuild
[Program]
:
src/foo/bar.c
    --misra_2004=none

我不知道为什么，但这对于包括INTEGRITY.h在内的所有内容都是必需的。

Answer 3

简单的答案是：这取决于您的工具链-但我希望如此。

通常，您可以配置要检查的头文件-例如，可以将LDRA ToolSuite配置为检查项目头（#include "xxx.h"），但不能检查系统头（#include <xxx.h>）

静态分析选项->包含搜索->不要扩展
