Heck, I'll even send you patches.  ;-)
You can run these tests yourself -- I think you'll see failures in
ldc/stc (patch to follow), and daa/das (not implemented yet), and
shal/shll (carry is wrong, patch to follow).

Install the patch in src/sim/testsuite/sim/h8300 (except for the
configure change, which goes in src/sim.  Run configure, build, 
install (required), and then cd build/sim/testsuite and run 
	make check RUNTESTFLAGS=allinsn.exp

It runs pretty quickly.
