Options
-------

   `as' supports the following additional command-line options for the
V850 processor family:

`-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.

`-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.

`-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.

`-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.

`-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.
