We have an autoconf check for stdatomic.h. The test even verifies that a program with atomic_load_explicit() compiles and links. How do we want to use mimalloc in the future? Is it going to stay optional in 3.12? Then the default setting for --with-mimalloc should depend on presence of stdatomic.h. Do we want to make it mandatory for GC heap walking and nogil? Then --with-mimalloc should default to "yes" and configure should abort when stdatomic.h is missing. I'm leaning towards --with-mimalloc=yes. It will make users aware that they need a compiler with atomics: configure: error: --with-mimalloc requires stdatomic.h. Update your compiler or rebuild with --without-mimalloc. Python 3.12 will require stdatomic. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46657> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
