+Current QEMU limitations:
+
+@itemize
+
+@item Tagged add/subtract instructions are not supported, but they are
+probably not used.
+
+@item IPC syscalls are missing.
+
+@item 128-bit floating point operations are not supported, though none of the
+real CPUs implement them either. FCMPE[SD] are not correctly
+implemented. Floating point exception support is untested.
+
+@item Alignment is not enforced at all.
+
+@item Atomic instructions are not correctly implemented.
+
+@item Sparc64 emulators are not usable for anything yet.
