Message-ID: <10402042058.AA03771@vlsi1.ultra.nyu.edu> (raw)
It _can_ be made explicit. We may not know the actual value, but for a
given expression we do know which instance we want to extract it from
(by walking back to a corresponding WITH_RECORD_EXPR).
But there *is* no corresponding WITH_RECORD_EXPR when the expression
is used as a size, offset or bound: that's precisely the point.
Sure, when there is such an expression it can indeed be folded (or not even
generated at all).
