Bug ID: 51452
Summary: Namespace inline mismatch diagnostic refers to
unhelpful previous definition
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: tbae...@redhat.com
CC: llvm-bugs@lists.llvm.org, neeil...@live.com,
richard-l...@metafoo.co.uk
See: https://godbolt.org/z/x87K78TnW
Take this C++ code:
1: inline namespace abc {};
2: namespace abc {};
3: namespace abc {};
Clang will emit a warning for line 2, because the namespace is re-opened as
non-inline, while the previous definition was inline. It will add a Note for
the previous definition, in this case line 1.
However, it will also emit the same warning for line 3. In this case, it would
be helpful to have the Note refer to the definition in line 1, but it instead
refers to line 2. That is confusing since the problem is the inline mismatch,
but the Note refers to a definition that is not inline.
