<h4 class="subsection">M32R/D Options</h4>
<p>These <code>-m</code> options are defined for Mitsubishi M32R/D architectures:
<dl>
<dt><code>-m32rx</code>
<dd>Generate code for the M32R/X.
<br><dt><code>-m32r</code>
<dd>Generate code for the M32R. This is the default.
<br><dt><code>-mcode-model=small</code>
<dd>Assume all objects live in the lower 16MB of memory (so that their addresses
can be loaded with the <code>ld24</code> instruction), and assume all subroutines
are reachable with the <code>bl</code> instruction.
This is the default.
<p>The addressability of a particular object can be set with the
<code>model</code> attribute.
<br><dt><code>-mcode-model=medium</code>
<dd>Assume objects may be anywhere in the 32-bit address space (the compiler
will generate <code>seth/add3</code> instructions to load their addresses), and
assume all subroutines are reachable with the <code>bl</code> instruction.
<br><dt><code>-mcode-model=large</code>
<dd>Assume objects may be anywhere in the 32-bit address space (the compiler
will generate <code>seth/add3</code> instructions to load their addresses), and
assume subroutines may not be reachable with the <code>bl</code> instruction
(the compiler will generate the much slower <code>seth/add3/jl</code>
instruction sequence).
<br><dt><code>-msdata=none</code>
<dd>Disable use of the small data area. Variables will be put into
one of <code>.data</code>, <code>bss</code>, or <code>.rodata</code> (unless the
<code>section</code> attribute has been specified).
This is the default.
<p>The small data area consists of sections <code>.sdata</code> and <code>.sbss</code>.
Objects may be explicitly put in the small data area with the
<code>section</code> attribute using one of these sections.
<br><dt><code>-msdata=sdata</code>
<dd>Put small global and static data in the small data area, but do not
generate special code to reference them.
<br><dt><code>-msdata=use</code>
<dd>Put small global and static data in the small data area, and generate
special instructions to reference them.
<br><dt><code>-G </code><var>num</var><code></code>
<dd>Put global and static objects less than or equal to <var>num</var> bytes
into the small data or bss sections instead of the normal data or bss
sections. The default value of <var>num</var> is 8.
The <code>-msdata</code> option must be set to one of <code>sdata</code> or <code>use</code>
for this option to have any effect.
<p>All modules should be compiled with the same <code>-G </code><var>num</var><code></code> value.
Compiling with different values of <var>num</var> may or may not work; if it
doesn't the linker will give an error message--incorrect code will not be
generated.
