The ARM MVE floating-point intrinsic tests now explicitly set the -mtune=cortex-m55 flag. This overrides any default tuning provided by DejaGNU, guaranteeing that the generated assembly is stable and predictable for testing purposes. Several intrinsic test files have been updated to incorporate this change.
