m32c has no problem loading a 24-bit register from a 32-bit memory
location.

Does that mean that Sd* is as good as m?

I suggest making reload reload the PSImode subreg instead, and

From looking at the m32c machine description I got the impression
that you can't directly load A_REGS in PSImode from a PSImode subreg
