Marc,
I first worked with the SSA form twenty years ago so yes I am
aware of what a phi is... I've just never s

No, I have no control over that but I'll give the email of our corporate

Hi
g++.dg/abi/guard3.C
has:
extern "C" int __cxa_guard_acquire();
Which might not be a suitable declaration, depending on how the ‘extern
“C”’ is supposed to affect the function signature generated.
IF, the extern C should make this parse as a “K&R” style function - then

Snapshot gcc-11-20200906 is now available on
https://gcc.gnu.org/pub/gcc/snapshots/11-20200906/
and on various mirrors, see http://gcc.gnu.org/mirrors.html for details.
This snapshot has been generated from the GCC 11 git branch
with the following options: git://gcc.gnu.org/git/gcc.git branch
GCC has an extension on machaines with cxx_implicit_extern_c (what used to be
!NO_IMPLICIT_EXTERN_C).
On such targets we'll treat 'extern "C" void Foo ()' as-if the argument list is
variadic. (or something approximating that)
perhaps that is confusing things?
