      Goal

      • As a user of aarch64 based systems I want to be able to identify which system hardware capabilities glibc can detect or query, so that I can understand which hardware dependent code paths are taken, and that I can feed this information back to the glibc project in order to add support for yet unsupported hardware capabilities.

      Acceptance Criteria

      A list of verification conditions, successful functional tests, or expected outcomes in order to declare this story/task successfully completed.

      • ld.so --list-diagnostics on aarch64 outputs information similar to the x86_64 platform:
      $ ld.so --list-diagnostics | grep cpu_features
