--- Comment #11 from Rainer Orth <ro at gcc dot gnu.org> ---
As already mentioned on gcc-patches, the patch broke sparcv9-sun-solaris2.*
bootstrap (unlike sparc-sun-solaris2.*, which is still fine):

/vol/gcc/src/hg/trunk/local/gcc/reload1.c: In function 'void
elimination_costs_in_insn(rtx_insn*)':

     *recog_data.dup_loc[i] = orig_dup[i];
                                         ^
