These ones are irrelevant to the config but rather to the platform, and as such are better placed in compiler.h. Here we take the opportunity for declaring a few extra capabilities: - HA_UNALIGNED : CPU supports unaligned accesses - HA_UNALIGNED_LE : CPU supports unaligned accesses in little endian - HA_UNALIGNED_FAST : CPU supports fast unaligned accesses - HA_UNALIGNED_ATOMIC : CPU supports unaligned accesses in atomics This will help remove a number of #ifdefs with arch-specific statements.
