------- Comment #4 from hp at gcc dot gnu dot org  2008-10-22 22:05 -------

Updated cris.h patch, reflecting corrected REGNO_REG_CLASS together with the
IRA_COVER_CLASSES.

I tried this updated cris.h patch as per previous comment together with
r141228, but it ICE's compiling newlib's ldtoa.c.  See next attachment.
