If the set of targets are all little or all big endian, re-declare as DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN respectively. Then, on inspection: - if not used, re-declare as DEVICE_HOST_ENDIAN. - if max/min size=3D1, re-declare as DEVICE_HOST_ENDIAN. - if just a bit bucket, re-declare as DEVICE_HOST_ENDIAN - if PCI, re-declare as DEVICE_LITTLE_ENDIAN. - if for {ARM|unicore32} only, re-declare as DEVICE_LITTLE_ENDIAN. - if for SPARC only, re-declare as DEVICE_BIG_ENDIAN.
