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.
Address space is limited to first 4 gigabytes.
