What you are suggesting is the first solution that i got from Richard Henderson. I have mentioned the issues if faced with this in my mail. The GCC frame work is written assuming that there are no modes with HOST_BITS_PER_WIDE_INT < GET_MODE_BITSIZE (mode) < 2 * HOST_BITS_PER_WIDE_INT. So i had to hack at places to get things working. For my target the BITS_PER_WORD == 32. The mode that i am using is RImode (5bytes)
