            Bug ID: 50791
           Summary: lld/mac mislinks binaries (protoc, chromium, ...) on
                    arm with --deduplicate-literals
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: MachO

Link using the response file, then run like so:

./protoc csd.proto --cpp_out .          

Then look at csd.pb.h in the output. Line 45 will say

  static const ::r_PROTO_NAMESPACE_ID::internal::ParseTableField entries[]

There's a \0 character in the middle of the line, and the line's all wrong.

Remove --deduplicate-literals from that line, link again, and that line looks
like

  static const ::PROTOBUF_NAMESPACE_ID::internal::ParseTableField entries[]

like it's supposed to do.
