+@code{@value{AS}} supports the following additional command-line options
+for the V850 processor family:
+
+@cindex command line options, V850
+@cindex V850 command line options
+@table @code
+
+@cindex @code{-wsigned_overflow} command line option, V850
+@item -wsigned_overflow
+Causes warnings to be produced when signed immediate values overflow the
+space available for then within their opcodes. By default this option
+is disabled as it is possible to receive spurious warnings due to using
+exact bit patterns as immediate constants.
+
+@cindex @code{-wunsigned_overflow} command line option, V850
+@item -wunsigned_overflow
+Causes warnings to be produced when unsigned immediate values overflow
+the space available for then within their opcodes. By default this
+option is disabled as it is possible to receive spurious warnings due to
+using exact bit patterns as immediate constants.
+
+@cindex @code{-mv850} command line option, V850
+@item -mv850
+Specifies that the assembled code should be marked as being targeted at
+the V850 processor. This allows the linker to detect attempts to link
+such code with code assembled for other processors.
+
+@cindex @code{-mv850e} command line option, V850
+@item -mv850e
+Specifies that the assembled code should be marked as being targeted at
+the V850E processor. This allows the linker to detect attempts to link
+such code with code assembled for other processors.
+
+@cindex @code{-mv850e1} command line option, V850
+@item -mv850e1
+Specifies that the assembled code should be marked as being targeted at
+the V850E1 processor. This allows the linker to detect attempts to link
+such code with code assembled for other processors.
+
+@cindex @code{-mv850any} command line option, V850
+@item -mv850any
+Specifies that the assembled code should be marked as being targeted at
+the V850 processor but support instructions that are specific to the
+extended variants of the process. This allows the production of
+binaries that contain target specific code, but which are also intended
+to be used in a generic fashion. For example libgcc.a contains generic
+routines used by the code produced by GCC for all versions of the v850
+architecture, together with support routines only used by the V850E
+architecture.
+
+@cindex @code{-mv850e2} command line option, V850
+@item -mv850e2
+Specifies that the assembled code should be marked as being targeted at
+the V850E2 processor. This allows the linker to detect attempts to link
+such code with code assembled for other processors.
+
+@cindex @code{-mv850e2v3} command line option, V850
+@item -mv850e2v3
+Specifies that the assembled code should be marked as being targeted at
+the V850E2V3 processor. This allows the linker to detect attempts to link
+such code with code assembled for other processors.
+
+@cindex @code{-mv850e2v4} command line option, V850
+@item -mv850e2v4
+This is an alias for @option{-mv850e3v5}.
+
+@cindex @code{-mv850e3v5} command line option, V850
+@item -mv850e3v5
+Specifies that the assembled code should be marked as being targeted at
+the V850E3V5 processor. This allows the linker to detect attempts to link
+such code with code assembled for other processors.
+
+@cindex @code{-mrelax} command line option, V850
+@item -mrelax
+Enables relaxation. This allows the .longcall and .longjump pseudo
+ops to be used in the assembler source code. These ops label sections
+of code which are either a long function call or a long branch. The
+assembler will then flag these sections of code and the linker will
+attempt to relax them.
+
+@cindex @code{-mgcc-abi} command line option, V850
+@item -mgcc-abi
+Marks the generated objecy file as supporting the old GCC ABI.
+
+@cindex @code{-mrh850-abi} command line option, V850
+@item -mrh850-abi
+Marks the generated objecy file as supporting the RH850 ABI. This is
+the default.
+
+@cindex @code{-m8byte-align} command line option, V850
+@item -m8byte-align
+Marks the generated objecy file as supporting a maximum 64-bits of
+alignment for variables defined in the source code.
+
+@cindex @code{-m4byte-align} command line option, V850
+@item -m4byte-align
+Marks the generated objecy file as supporting a maximum 32-bits of
+alignment for variables defined in the source code. This is the
+default.
