Hi Eric,
Note that the very same code is in expand_assignment, so they probably should
be kept in sync.
Oops - I had missed that.
The patch adds a second call to expand_expr(), giving the address mode
as the suggested mode, and using a normal expansion, rather than
EXPAND_SUM.
This function is unused since matrix-reorg.c removal back in 2012. I think
there's no point in keeping it around.
