file in a format different from that of the source object file. The
exact behavior of @code{objcopy} is controlled by command-line options.
+Note that @code{objcopy} should be able to copy a fully linked file
+between any two formats. However, copying a relocatable object file
+between any two formats may not work as expected.
@code{objcopy} creates temporary files to do its translations and
deletes them afterward. @code{objcopy} uses @sc{bfd} to do all its

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.
+@samp{-M 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{-M reg-names-apcs} will select the name set used by the ARM

+There are also two variants on the APCS register naming scheme enabled

+use the ARM/Thumb Procedure Call Standard naming conventions. (Eiuther

+
+This option can also be used for ARM architectures to force the

+using the switch @samp{--disassembler-options=force-thumb}. This can be
+useful when attempting to disassemble thumb code produced by other
+compilers.
