<pre>
    The `llvmlibc-inline-function-decl` check currently reports erroneously  on nested template parameters. Here is a reproducer.
```c++
#define LIBC_INLINE inline

namespace __llvm_libc {

template <typename T> struct S {
  template <typename U> void foo();
};

template <typename T> template <typename U> LIBC_INLINE void S<T>::foo() {}
} // namespace __llvm_libc
```

```
$> clang-tidy test.h --checks=-'*,llvmlibc*'
2 warnings generated.
/home/jhuber/Documents/llvm/llvm-project/build/test.h:9:1: warning: 'foo' must be tagged with the LIBC_INLINE macro; the macro should be placed at the beginning of the declaration [llvmlibc-inline-function-decl]
template <typename T> template <typename U> LIBC_INLINE void S<T>::foo() {}
