        * cselib.h (rtx_equal_for_cselib_1): Add depth argument.
        (rtx_equal_for_cselib_p): Pass 0 to it.
        * cselib.c (cselib_hasher::equal): Likewise.
        (rtx_equal_for_cselib_1): Add depth argument.  If depth
        is 128, don't look up VALUE locs and punt.  Increment
        depth in recursive calls when walking VALUE locs.

        * gcc.dg/torture/pr80025.c: New test.
