<a name="index-FRV-Options"></a>

<dl compact="compact">
<dt><code>-mgpr-32</code></dt>
<dd><a name="index-mgpr_002d32"></a>

<p>Only use the first 32 general-purpose registers.
</p>
</dd>
<dt><code>-mgpr-64</code></dt>
<dd><a name="index-mgpr_002d64"></a>

<p>Use all 64 general-purpose registers.
</p>
</dd>
<dt><code>-mfpr-32</code></dt>
<dd><a name="index-mfpr_002d32"></a>

<p>Use only the first 32 floating-point registers.
</p>
</dd>
<dt><code>-mfpr-64</code></dt>
<dd><a name="index-mfpr_002d64"></a>

<p>Use all 64 floating-point registers.
</p>
</dd>
<dt><code>-mhard-float</code></dt>
<dd><a name="index-mhard_002dfloat-1"></a>

<p>Use hardware instructions for floating-point operations.
</p>
</dd>
<dt><code>-msoft-float</code></dt>
<dd><a name="index-msoft_002dfloat-3"></a>

<p>Use library routines for floating-point operations.
</p>
</dd>
<dt><code>-malloc-cc</code></dt>
<dd><a name="index-malloc_002dcc"></a>

<p>Dynamically allocate condition code registers.
</p>
</dd>
<dt><code>-mfixed-cc</code></dt>
<dd><a name="index-mfixed_002dcc"></a>

<p>Do not try to dynamically allocate condition code registers, only
use <code>icc0</code> and <code>fcc0</code>.
</p>
</dd>
<dt><code>-mdword</code></dt>
<dd><a name="index-mdword"></a>

<p>Change ABI to use double word insns.
</p>
</dd>
<dt><code>-mno-dword</code></dt>
<dd><a name="index-mno_002ddword"></a>
<a name="index-mdword-1"></a>

<p>Do not use double word instructions.
</p>
</dd>
<dt><code>-mdouble</code></dt>
<dd><a name="index-mdouble-1"></a>

<p>Use floating-point double instructions.
</p>
</dd>
<dt><code>-mno-double</code></dt>
<dd><a name="index-mno_002ddouble"></a>

<p>Do not use floating-point double instructions.
</p>
</dd>
<dt><code>-mmedia</code></dt>
<dd><a name="index-mmedia"></a>

<p>Use media instructions.
</p>
</dd>
<dt><code>-mno-media</code></dt>
<dd><a name="index-mno_002dmedia"></a>

<p>Do not use media instructions.
</p>
</dd>
<dt><code>-mmuladd</code></dt>
<dd><a name="index-mmuladd"></a>

<p>Use multiply and add/subtract instructions.
</p>
</dd>
<dt><code>-mno-muladd</code></dt>
<dd><a name="index-mno_002dmuladd"></a>

<p>Do not use multiply and add/subtract instructions.
</p>
</dd>
<dt><code>-mfdpic</code></dt>
<dd><a name="index-mfdpic-1"></a>

<p>Select the FDPIC ABI, which uses function descriptors to represent
pointers to functions.  Without any PIC/PIE-related options, it
implies <samp>-fPIE</samp>.  With <samp>-fpic</samp> or <samp>-fpie</samp>, it
assumes GOT entries and small data are within a 12-bit range from the
GOT base address; with <samp>-fPIC</samp> or <samp>-fPIE</samp>, GOT offsets
are computed with 32 bits.
With a &lsquo;<samp>bfin-elf</samp>&rsquo; target, this option implies <samp>-msim</samp>.
</p>
</dd>
<dt><code>-minline-plt</code></dt>
<dd><a name="index-minline_002dplt-1"></a>

<p>Enable inlining of PLT entries in function calls to functions that are
not known to bind locally.  It has no effect without <samp>-mfdpic</samp>.
It&rsquo;s enabled by default if optimizing for speed and compiling for
shared libraries (i.e., <samp>-fPIC</samp> or <samp>-fpic</samp>), or when an
optimization option such as <samp>-O3</samp> or above is present in the
command line.
</p>
</dd>
<dt><code>-mTLS</code></dt>
<dd><a name="index-mTLS"></a>

<p>Assume a large TLS segment when generating thread-local code.
</p>
</dd>
<dt><code>-mtls</code></dt>
<dd><a name="index-mtls"></a>

<p>Do not assume a large TLS segment when generating thread-local code.
</p>
</dd>
<dt><code>-mgprel-ro</code></dt>
<dd><a name="index-mgprel_002dro"></a>

<p>Enable the use of <code>GPREL</code> relocations in the FDPIC ABI for data
that is known to be in read-only sections.  It&rsquo;s enabled by default,
except for <samp>-fpic</samp> or <samp>-fpie</samp>: even though it may help
make the global offset table smaller, it trades 1 instruction for 4.
With <samp>-fPIC</samp> or <samp>-fPIE</samp>, it trades 3 instructions for 4,
one of which may be shared by multiple symbols, and it avoids the need
for a GOT entry for the referenced symbol, so it&rsquo;s more likely to be a
win.  If it is not, <samp>-mno-gprel-ro</samp> can be used to disable it.
</p>
</dd>
<dt><code>-multilib-library-pic</code></dt>
<dd><a name="index-multilib_002dlibrary_002dpic"></a>

<p>Link with the (library, not FD) pic libraries.  It&rsquo;s implied by
<samp>-mlibrary-pic</samp>, as well as by <samp>-fPIC</samp> and
<samp>-fpic</samp> without <samp>-mfdpic</samp>.  You should never have to use
it explicitly.
</p>
</dd>
<dt><code>-mlinked-fp</code></dt>
<dd><a name="index-mlinked_002dfp"></a>

<p>Follow the EABI requirement of always creating a frame pointer whenever
a stack frame is allocated.  This option is enabled by default and can
be disabled with <samp>-mno-linked-fp</samp>.
</p>
</dd>
<dt><code>-mlong-calls</code></dt>
<dd><a name="index-mlong_002dcalls-4"></a>

<p>Use indirect addressing to call functions outside the current
compilation unit.  This allows the functions to be placed anywhere
within the 32-bit address space.
</p>
</dd>
<dt><code>-malign-labels</code></dt>
<dd><a name="index-malign_002dlabels"></a>

<p>Try to align labels to an 8-byte boundary by inserting NOPs into the
previous packet.  This option only has an effect when VLIW packing
is enabled.  It doesn&rsquo;t create new packets; it merely adds NOPs to
existing ones.
</p>
</dd>
<dt><code>-mlibrary-pic</code></dt>
<dd><a name="index-mlibrary_002dpic"></a>

<p>Generate position-independent EABI code.
</p>
</dd>
<dt><code>-macc-4</code></dt>
<dd><a name="index-macc_002d4"></a>

<p>Use only the first four media accumulator registers.
</p>
</dd>
<dt><code>-macc-8</code></dt>
<dd><a name="index-macc_002d8"></a>

<p>Use all eight media accumulator registers.
</p>
</dd>
<dt><code>-mpack</code></dt>
<dd><a name="index-mpack"></a>

<p>Pack VLIW instructions.
</p>
</dd>
<dt><code>-mno-pack</code></dt>
<dd><a name="index-mno_002dpack"></a>

<p>Do not pack VLIW instructions.
</p>
</dd>
<dt><code>-mno-eflags</code></dt>
<dd><a name="index-mno_002deflags"></a>

<p>Do not mark ABI switches in e_flags.
</p>
</dd>
<dt><code>-mcond-move</code></dt>
<dd><a name="index-mcond_002dmove"></a>

<p>Enable the use of conditional-move instructions (default).

<dd><a name="index-mvliw_002dbranch"></a>

<p>Run a pass to pack branches into VLIW instructions (default).
</p>
<p>This switch is mainly for debugging the compiler and will likely be removed
in a future version.
</p>
</dd>
<dt><code>-mno-vliw-branch</code></dt>
