My understand of the current trunk, updated and compiled daily from git,
on Linux x86-64/64 Debian or Linux Ubuntu 12.2.0)GNU Emacs 30.0.50
Development version d5ab8b6f2459 on master branch; build date 2023-05-07
is that such a function cannot exist.
On recent GNU emacs, the internal fonctions are JIT compiled (using
gcclibjit from GCC 13) by the gccasmjit library, and we get:

Notice the dependency on libgccjit.so.0, which is provided by GCC 12 or
GCC 13 suitably configured
That thing is used in GNU emacs source code. Look into its ffile
emacs/src/comp.c (line 553, etc... 4689)
On the same system the Ubuntu emacs don't use libgccjit.
But perhaps I misunderstood your question?
Regards.
