ICE in change_address at emit_rtl.c

[Richard Kenner]

    I'm not sure what the problem is.  My proposal is to use some kind of
    LET_EXPR, which takes a declaration and two expressions.  It seems
    plausible to me that any place that creates a SAVE_EXPR could use a
    LET_EXPR instead. 

So how are you changing things?  You're replacing SAVE_EXPR with LET_EXPR
with similar semantics.
