            Bug ID: 48347
           Summary: Method metadata emitted twice from synthesised
                    properties targeting GNU Objective-C runtimes
           Product: clang
           Version: 11.0
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: LLVM Codegen
          Assignee: unassignedclangbugs at nondot.org
          Reporter: csdavec at swan.ac.uk

            Blocks: 47800

The clang AST was refactored to add method nodes for methods synthesised from
Objective-C properties but the GNU runtime (ABIv1) code that emitted runtime
metadata was not updated so these methods were emitted twice.  This was fixed
in trunk:

d1ed67037de6f3f44dc446784f74f0e02adec9b5

Please can this be added to the 11 point release?
