My bad, -m32. I've beta tested the compiler and I can confirm it works.

The compiler supports a -m31 flag and ships with a 31bit runtime library.

Got it. Must insert some sort of glue if you call a method declared AMODE 31.
I wonder how it handles data areas in that situation. I wonder if you have to
malloc31() if you are going to pass the data to a 31-bit method. What about C++
new? Perhaps you cannot pass classes to non-clang/LLVM programs, and they are
all AMODE 64. I guess that would be okay.
Still would like to RTFM. I guess I am a dinosaur.

Didn't say it ran in AMODE 31. Said it can call AMODE 31 programs.

The cited blog says "generates AMODE 64 code."
Is there any actual documentation, or am I being old-fashioned?

The new clang/LLVM C/C++ compiler has been announced
https://community.ibm.com/community/user/ibmz-and-linuxone/blogs/robert-barrington1/2022/04/05/next-generation-of-ibm-cc-and-fortran-compilers-av.
I suppose it was wishful thinking to expect it to be free as IBM have
commit a lot of resources to making it happen. It's only available to
customers who have a license for the XL C/C++ compiler. If you use C/C++
I highly recommend this compiler. It's modern supporting all the latest
language standards and is a significant improvement on the
xlclang/xlclang++ compilers previously shipped. It supports AMODE 31 for
interop with legacy code whereas xlclang was 64-bit only.
If you are interested in a free C/C++ compiler then Rocket have open
sourced their gcc/glibc z/OS port. It's a cross compiler so you build on
a Linux or Windows machine. AFAIK, glibc is fairly complete but is
missing pthreads.
