Regarding using liniearize instruction vs rolling your own.
I don't think you can get more information than linearize instruction
here. EXPR_DEREF has already been processed during evaluation.
Recall the history of the code: show-parse.c -> compile-i386.c ->
s2l-gen.c.
You can see the above code was taken verbatim from show-parse.c, and is
probably nothing more than a check the original author (Linus?) felt
appropriate at the time, for show-parse.c. I wouldn't read too much
into its presence in s2l-gen.c -- maybe those checks can simply be deleted.
