> gcc/ChangeLog:
>         PR rtl-optimization/100264
>         * ree.c (get_sub_rtx): Ignore SET expressions without register
>         destinations and remove assertion, as it is not valid anymore
>         with this new behaviour.
>         (merge_def_and_ext): Eliminate destination check for register
>         as such SET expressions can't occur anymore.
>         (combine_reaching_defs): Likewise.

The revised patch looks OK to me, and passed my testing.  I pushed it.
