Hi Dhananjay,

Thanks.

Why not h8300-*?  We should care for the COFF target as long as it's
there.

Would the same problem exist on the plain H8/300 then?  IIRC, H8 is
pretty lenient about alignment, but I don't know how lenient it is.
Or is it the case that no plain H8/300 supports 16-bit data bus or
something?

By the way, which version of GCC did you run the testsuite for?

Currently, h8300-elf on mainline doesn't build, so I'll apply your
patch after the build is restored.  Meanwhile, you might want to post
a complete patch with the testcase and ChangeLog entries to
gcc-patches for the record.
