--- Comment #4 from Martin Sebor <msebor at gcc dot gnu.org> ---
I had stated my intent in the initial submission to complete the C++ suppor=
t in
a followup patch:
https://gcc.gnu.org/pipermail/gcc-patches/2018-November/510455.html

Jason approved the initial patch with an encouragement to do so:
https://gcc.gnu.org/legacy-ml/gcc-patches/2018-10/msg01528.html

I might have gotten around to it if you and Jeff hadn't blocked for four mo=
nths
(!) my fixes for a few simple ICEs in the code.  Here's the first submissio=
n of
a patch for the first ICE I found in December 2018:
https://gcc.gnu.org/pipermail/gcc-patches/2018-December/512645.html

The fixes didn't get approved and committed in r270326 until April 2019, and
many rounds of back and forth bickering over whether the built-in should ac=
cept
expressions or error out on them.=
