            Bug ID: 51822
           Summary: False positive#pragma visibility pop with no matching
                    #pragma visibility push
           Product: clang-tools-extra
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: clangd
          Assignee: unassignedclangbugs at nondot.org
          Reporter: peter at eisenlohr.org

We are receiving false positives from clangd:

  #pragma visibility pop with no matching #pragma visibility push

Minimal testcase that reproduces this:

  #pragma GCC visibility push(default)
  namespace xyz {}
  #pragma GCC visibility pop

Instead of the namespace, any other declaration I tried resulted in the same
problem. Only if there is no other C++ code between the push and pop, the
message disappears.

It seems this only happens with clangd. I tried to write a testcase for this by
modifying one of the tests in clang-tools-extra/test/clang-tidy, but the
problem doesn't show there. I'm not sure how to write a clangd-testcase for
this, so I'm here just reporting this.

This happens with pre-build clangd as well as with custom builds of 12.x, 13.x
and main branches.
