Hello Sumanth, and everyone,
Thank you for your reply.

Try changing MINIMUM_UNITS_PER_WORD to greater than or equal to 2 in ur
target.h file
I think you mean MIN_UNITS_PER_WORD in gcc/config/h8300/h8300.h.
Unfortunately it was defined 2.
Here are excerpts from gcc/config/h8300/h8300.h that is converted according
to patch,
which has been previously sent as
patch-sources/gcc4.4.0-patch-converted-sources/h8300.h.
