    PR rtl-optimization/46865
    * rtl.c (rtx_equal_p_cb, rtx_equal_p): For last operand of
    ASM_OPERANDS and ASM_INPUT if integers are different,
    call locator_eq.
    * jump.c (rtx_renumbered_equal_p): Likewise.

    * gcc.target/i386/pr46865-1.c: New test.
    * gcc.target/i386/pr46865-2.c: New test.
