--- Comment #2 from Jeffrey A. Law <law at redhat dot com> --- I wasn't ever happy with the discrepancy between the computation of TO_ALLOCATE in the layout code and ALLOCATE within ix86_expand_prologue. It seemed ripe to fall into this kind of problem. sigh. If ALLOCATE was that small we don't need to do any probing unless the current function is marked as noreturn. I wonder if deferring the assertion to the point where we actually need the scratch or are going to call the msft probe function is possible.
