Is there a way to unassemble code of different bitness?

Is there a way to unassemble x64 code from an x86 process context
and vice versa, x86 code from x64 process context?

The ‘u’ command assumes that the code has the same bitness
as the current context and is not correct for dynamic code generation.

I would like to have /16, /32, /64, /IA64 options for the ‘u’ command
to explicitly unassemble 16-bit real mode, 32-bit x86, 64-bit x64,
and 64-bit Itanium code.

Use the ‘.effmach ’ command to specify the effective machine type.
