fmov.d has a byte order problem in little endian.  I guess that
-mfmovd is default on SH2A because SH2A is big endian only,
though I know nothing about the history of SH2A support.

I can't reproduce it with my unified tree&sim and couldn't find
any description for 8-byte alignment restriction for double
data on memory in my SH2A manual, though I could be wrong about
that.
Have you got this error on the real SH2A-FPU hardware?
