I'm not quite that sure about the general applicability of these, as
these depend somewhat on code size. Although there might be something
we can prove about a minimum frame size for one test or the other at -O0.
I also tried to add
/* { dg-skip-if "memory tight" { !size20plus } { "-O3" } } */
and
/* { dg-require-effective-target size20plus } */
to gcc.c-torture/execute/builtins/snprintf-chk.c , but to no avail.

* gcc.dg/fixed-point/convert-float-4.c: Require size20plus.
* gcc.dg/torture/pr112282.c: Skip if -O0 unless size20plus.
* g++.dg/lookup/pr21802.C: Require size20plus.
