I am not quite sure what part you are referring to.  In his response,
Bernd Schmidt uses the MODE_COMPLEX example as something that should
be synthesized correctly in expr.c (see,
http://gcc.gnu.org/ml/gcc-patches/2000-04/msg00099.html).

In the bug that I saw
(http://gcc.gnu.org/ml/gcc-patches/2002-08/msg00288.html) the problem
occured when one complex move was synthesized by two DI moves and not
when DI moves were synthesized (they are not synthesized for Thumb
anyway).

Can you clarify for me please.

Thanks,
Adam
