for the V850 processor family:

<dl><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.
<p><a name="index-_0040code_007b_002dwunsigned_005foverflow_007d-command-line-option_002c-V850-1788"></a><br><dt><code>-wunsigned_overflow</code><dd>Causes warnings to be produced when unsigned immediate values overflow

option is disabled as it is possible to receive spurious warnings due to
using exact bit patterns as immediate constants.
<p><a name="index-_0040code_007b_002dmv850_007d-command-line-option_002c-V850-1789"></a><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.
<p><a name="index-_0040code_007b_002dmv850e_007d-command-line-option_002c-V850-1790"></a><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.
<p><a name="index-_0040code_007b_002dmv850e1_007d-command-line-option_002c-V850-1791"></a><br><dt><code>-mv850e1</code><dd>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.
<p><a name="index-_0040code_007b_002dmv850any_007d-command-line-option_002c-V850-1792"></a><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.
<p><a name="index-_0040code_007b_002dmrelax_007d-command-line-option_002c-V850-1793"></a><br><dt><code>-mrelax</code><dd>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.
