gcc11-pr99456.patch looks good, can we add a scan-not for the _ZGV guard
variables too? If the optimizer's turned on, I think __static_init... gets
inlined into the global constructor, might be good to mak

I'm not misreading the testcase, I'm just reacting on the fact that my patch
changed the behavior of it and looking into related issues when analyzing why.
It is up to the compiler to decide if it can or can'

You're misreading this particular testcase. I don't believe it contains
anything invalid -- the only constexpr is on:
static constexpr unsigned &descRef = desc;
(and I don't think it's necessary there, bu

Another thing is that perhaps we should be rejecting reinterpret_cast only in
the
pedantic constant expression evaluation mode, not when we allow extensions and
fold as much as we can. So something like (inc

On one side, we have still accepts-invalid issue, e.g. in your testcase:

--- Comment #4 from Nathan Sidwell ---
It's an ABI issue, because all compilers must agree on which parts of an inline
object are dynamically initialized. (gcc-11 does not agree with gcc-10).
consider:
inline Type Var = Expr;
That'll be emitt
