        PR target/66470
        * config/i386/i386.c (ix86_split_long_move): For collisions
        involving direct tls segment refs, move the UNSPEC_TP possibly
        wrapped in ZERO_EXTEND out of the address for lea, to each of
        the memory loads.

        * gcc.dg/tls/pr66470.c: New test.
        * gcc.target/i386/pr66470.c: New test.
