#ifndef __ARM_ARCH
/* ACLE standardises a set of pre-defines that describe the ARM architecture.
These were mostly implemented in GCC around GCC-4.8; older versions
have no, or only partial support. To provide a level of backwards
compatibility we try to work out what the definitions should be, given
the older pre-defines that GCC did produce. This isn't complete, but
it should be enough for use by routines that depend on this header. */
