+
+@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.

+@c start-santize-v850e
+@cindex @code{-mv850e} command line option, V850
