/* These loads cannot be compressed because only one compressed reg is
available (since args are passed in a0-a4, that leaves a5-a7 available, of
which only a5 is a compressed reg). Therefore the shorten_memrefs pass should
not attempt to rewrite these loads into a compressible format. It may not
be possible to avoid this because shorten_memrefs happens before reg alloc.
