Your patches are for 4.5.0 and sh_softfloat.patch can't be
applicable for trunk cleanly. Please provide patches against
svn trunk and the ChangeLog entries for them.
Here is an incomplete list of comments for sh_softfloat.patch:
*target*:
New macro TARGET_MATCH_ADJUST requires a doc patch.

It looks that sh_compare_op0 snd sh_compare_op1 are set but
not used.

Use add_reg_note here. Several other similar cases.

sh_softfp.patch looks basically OK to me, though I'm curious
with numbers for fp-bit.c/softfp/softfloat. Could you show us
some real speed&size numbers?
