   <p><code>as</code> supports the following additional command-line options

for the V850 processor family:



     <dl>



     <br><dt><code>-wsigned_overflow</code>

     <dd>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.



     <br><dt><code>-wunsigned_overflow</code>

     <dd>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.



     <br><dt><code>-mv850</code>

     <dd>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.



     <br><dt><code>-mv850e</code>

     <dd>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.



     <br><dt><code>-mv850any</code>

     <dd>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.
