使用gcovr时LCOV_EXCL_START/STOP不起作用

问题描述

限时删除！！

当我在我的C ++代码中添加LCOV_EXCL_START/STOP标记时，它似乎对我的gcovr报告没有任何影响.

When I add LCOV_EXCL_START/STOP tags to my C++ code, it does not seem to have any effect on my gcovr report.

有人知道为什么会这样吗?

Does someone know why this occurs?

我有以下内容:

$ tree
.
├── build
├── include
│   └── a.h
└── tests
    └── test_a.cpp

和

$ cat include/a.h
void f (bool x)
{
    // LCOV_EXCL_START
    if (x)
        throw 1;
    // LCOV_EXCL_STOP
}

和

$ cat tests/test_a.cpp
#include "a.h"

int main ()
{
    f (false);
    return 0;
}

但是第5行throw 1;包含在gcovr报告中，即使它被排除标记括起来也是如此:

But line 5 throw 1; is included in the gcovr report, even though it is surrounded in exclude tags:

$ g++ -c -O0 -fprofile-arcs -ftest-coverage -fPIC --coverage -I include ./tests/test_a.cpp -o ./build/test_a.o
$ g++ ./build/test_a.o -o ./build/test_a -lgcov
$ ./build/test_a
$ gcovr -r .
