Make a valgrind error suppression generic for an object library, with wildcards
问题
在C++项目中使用Valgrind，我一直在尝试抑制来自第三方库的内存泄漏信息。我会通过运行Valgrind并使用--gen-suppressions=all选项来生成特定的抑制文件条目，例如：
{<insert_a_suppression_name_here>Memcheck:Leakmatch-leak-kinds: reachablefun:mallocobj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/local/cuda-11.6/targets/x86_64-linux/lib/libcudart.so.11.6.55obj:/usr/local/cuda-11.6/targets/x86_64-linux/lib/libcudart.so.11.6.55obj:/usr/local/cuda-11.6/targets/x86_64-linux/lib/libcudart.so.11.6.55obj:/usr/local/cuda-11.6/targets/x86_64-linux/lib/libcudart.so.11.6.55}
现在我想通用化该规则，以便抑制来自任何名为*libcuda*的库的任何警告。我尝试了不同的方法，如：
{cudamemcheck:Leak...obj:*libcuda*...}
或者
{cudamemcheck:Leakobj:*libcuda*}
或者（受到这个回答的启发 this）
{cudamemcheck:Leakfun:*alloc...obj:*libcuda*...}
以上所有方法都不起作用，因此即使Valgrind在不报错的情况下读取了抑制文件，我的libcuda来源的消息也不会被抑制。是否有办法让Valgrind接受这种通用抑制命令？
英文:
Using valgrind in the context of a C++ project, I have been trying to suppress memory leak information coming from third party libraries. I would generate the specific suppression file entry running valgrind with --gen-suppressions=all and obtain for example:
{<insert_a_suppression_name_here>Memcheck:Leakmatch-leak-kinds: reachablefun:mallocobj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/lib/x86_64-linux-gnu/libcuda.so.515.105.01obj:/usr/local/cuda-11.6/targets/x86_64-linux/lib/libcudart.so.11.6.55obj:/usr/local/cuda-11.6/targets/x86_64-linux/lib/libcudart.so.11.6.55obj:/usr/local/cuda-11.6/targets/x86_64-linux/lib/libcudart.so.11.6.55obj:/usr/local/cuda-11.6/targets/x86_64-linux/lib/libcudart.so.11.6.55}
Now I would like to generalize that rule so that it suppresses any warning coming from any library called *libcuda*. I tried different things, like:
{cudamemcheck:Leak...obj:*libcuda*...}
or
{cudamemcheck:Leakobj:*libcuda*}
or (inspired by this)
{cudamemcheck:Leakfun:*alloc...obj:*libcuda*...}
None of this worked, so even if the suppression file is read by valgrind with no complaint, none of my libcuda originated messages get suppressed.
Is there a way to make Valgrind accept this kind of generic suppression commands?

主要问题是您将 Memcheck 拼写为小写 m。
以下内容将有效：
{cudaMemcheck:Leak...obj:*libcuda*}
您放置的最后一个帧通配符 ... 是不必要的。
英文:
The main problem is that you have mispelled Memcheck with lowercase m.
The following will work:
{cudaMemcheck:Leak...obj:*libcuda*}
The last frame wildcard ... you had put is not necessary.
