architecture information, such as S-records. You can list the available
architectures with the @option{-i} option.
+For most architectures it is possible to supply an architecture
+name and a machine name, separated by a colon. For example
+@samp{foo:bar} would refer to the @samp{bar} machine type in the
+@samp{foo} architecture. This can be helpful if objdump has been
+configured to support multiple architectures.

If the target is an ARM architecture then this switch has an
additional effect. It restricts the disassembly to only those
instructions supported by the architecture specified by @var{machine}.
