 If the target is an ARM architecture then this switch can be used to
 select which register name set is used during disassembler.  Specifying
-@samp{--disassembler-options=reg-name-std} (the default) will select the
-register names as used in ARM's instruction set documentation, but with
-register 13 called 'sp', register 14 called 'lr' and register 15 called
-'pc'.  Specifying @samp{--disassembler-options=reg-names-apcs} will
-select the name set used by the ARM Procedure Call Standard, whilst
-specifying @samp{--disassembler-options=reg-names-raw} will just use
-@samp{r} followed by the register number.

 This option can also be used for ARM architectures to force the
 disassembler to interpret all instructions as THUMB instructions by
