Why the !DECL_P check? Pulling the value out of a volatile INDIRECT_REF is just
as problematic as from a variable.
Hmm... my intent was to check that we are not dealing with an expression, i.e.
that should have been 'EXPR_P' rather than '!DECL_P'.
But why do you want to check that? My point is that the same issue can
occur with an expression. Can't you just check want_rval?
But now I wonder, if the combination 'TREE_THIS_VOLATILE (t) && EXPR_P (t) &&
!want_rval' is possible at all and should it be rejected?
It is possible for a volatile *_REF.
