        * tree-complex.c (expand_complex_move): Keep line info when expanding
        complex move.
        * tree-ssa-uninit.c (warn_uninit): New argument. Ignore assignment 
        of complex expression. Use new argument to display correct location 
        for values coming from phi statement.
        (warn_uninitialized_vars): Adapt to new signature of warn_uninit.
        (warn_uninitialized_phi): Pass location of phi argument to 
        warn_uninit.
        * tree-ssa.c (ssa_undefined_value_p): For SSA_NAME initialized by a
        COMPLEX_EXPR, recurse on each part of the COMPLEX_EXPR.

testsuite:

        * gcc.dg/uninit-13.c: Move warning on the actual source line where
        the uninitialized complex is used.
        * gcc.dg/uninit-17.c: New test to check partial initialization of
        complex with branches.
        * gcc.dg/uninit-17-O0.c: Likewise.
