+@option{cpu=...} allows to enforce a particular ISA when disassembling
+instructions, overriding the @option{-m} value or whatever is in the ELF file.
+This might be useful to select ARC EM or HS ISA, because architecture is same
+for those and disassembler relies on private ELF header data to decide if code
+is for EM or HS. This option might be specified multiple times - only the
+latest value will be used. Valid values are same as for the assembler
+@option{-mcpu=...} option.

If the target is an ARM architecture then this switch can be used to
select which register name set is used during disassembler. Specifying
@option{-M reg-names-std} (the default) will select the register names as
suffix even when the suffix could be inferred by the operands.
