+@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 object file as supporting the old GCC ABI.
+
+@cindex @code{-mrh850-abi} command line option, V850
+@item -mrh850-abi
+Marks the generated object file as supporting the RH850 ABI. This is
+the default.
+
+@cindex @code{-m8byte-align} command line option, V850
+@item -m8byte-align
+Marks the generated object 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 object file as supporting a maximum 32-bits of
+alignment for variables defined in the source code. This is the
+default.
+
+@cindex @code{-msoft-float} command line option, V850
+@item -msoft-float
+Marks the generated object file as not using any floating point
+instructions - and hence can be linked with other V850 binaries
+that do or do not use floating point. This is the default for
+binaries for architectures earlier than the @code{e2v3}.
+
+@cindex @code{-mhard-float} command line option, V850
+@item -mhard-float
+Marks the generated object file as one that uses floating point
+instructions - and hence can only be linked with other V850 binaries
+that use the same kind of floating point instructions, or with
+binaries that do not use floating point at all. This is the default
+for binaries the @code{e2v3} and later architectures.
