It seems so. I have a prreliminary patch to upstream CVS HEAD prepared, that depends on the patch for s390 port. As soon as upstream commits the s390 part, I'll post sh4 port patch there, including RISC_ALIGNMENT. It would be nice to be able to test the build before sending the patch upstream. Can you provide me access to sh4 hardware? Alternatively I can send you a tarball (or URL of a tarball) for you to try building it. -- dam
