The m68k2 code generator translates most EM instructions in line.
For some complex EM instructions it uses assembly routines (stored in the
-library "libem/libem_s.a"). It should be noted that some of these routines
-are not reentrant, because they save registers in a global common
-area (regsav).

The generated code does not check for array bound errors, overflow in
arithmetic operations or division by zero (the latter will cause a hardware
