Hi; I get compile failures, I'm afraid:

FreeBSD's compiler gives warnings:
In file included from /var/tmp/qemu-test.bVaUEj/accel/tcg/user-exec.c:28:
/var/tmp/qemu-test.bVaUEj/include/qemu/atomic128.h:148:23: warning:

Int128 __attribute__((error("unsupported atomic")))
                      ^

void __attribute__((error("unsupported atomic")))
                    ^

x86-64 Linux clang fails with the same issue:

The win32 build fails with:
