Question on aggregates and GIMPLE

[Richard Kenner]

    <MODIFY_EXPR <INDIRECT_REF, INDIRECT_REF>> is valid GIMPLE, and shouldn't
    require a temporary.  I think we're just getting confused by the
    VIEW_CONVERT_EXPR.

Well, how about <MODIFY_EXPR <COMPONENT_REF, INDIRECT_REF>>?  It appears to
be saying that if the LHS is "complex", the RHS must be a variable and
trying to make a temporary.

That's the latest problem I'm hitting (as of this morning: I was flying
most of the day).
