I'm not an authority on these matters, but I'm pretty sure that the sh5
ABI requires 32-bit values to be correctly sign-extended when held in
registers, regardless of the signedness of their type. I've certainly had
to tweak some sh5 asm to make sure unsigned 32-bit results are still
sign-extended.

You could send me your patches so I can try them on sh5 to see what
breaks, if anything. ;-)
