<h4 class="section">M32R Options</h4>



   <p>The Mitsubishi M32R version of <code>as</code> has a few machine

dependent options:



     <dl>

<dt><code>-m32rx</code>

     <dd><code>as</code> can assemble code for several different members of the

Mitsubishi M32R family.  Normally the default is to assemble code for

the M32R microprocessor.  This option may be used to change the default

to the M32RX microprocessor, which adds some more instructions to the

basic M32R instruction set, and some additional parameters to some of

the original instructions.



     <br><dt><code>-m32r</code>

     <dd>This option can be used to restore the assembler's default behaviour of

assembling for the M32R microprocessor.  This can be useful if the

default has been changed by a previous command line option.



     <br><dt><code>-warn-explicit-parallel-conflicts</code>

     <dd>Instructs <code>as</code> to produce warning messages when

questionable parallel instructions are encountered.  This option is

enabled by default, but <code>gcc</code> disables it when it invokes

<code>as</code> directly.  Questionable instructions are those whoes

behaviour would be different if they were executed sequentially.  For

example the code fragment <code>mv r1, r2 || mv r3, r1</code> produces a

different result from <code>mv r1, r2 \n mv r3, r1</code> since the former

moves r1 into r3 and then r2 into r1, whereas the later moves r2 into r1

and r3.



     <br><dt><code>-Wp</code>

     <dd>This is a shorter synonym for the <em>-warn-explicit-parallel-conflicts</em>

option.



     <br><dt><code>-no-warn-explicit-parallel-conflicts</code>

     <dd>Instructs <code>as</code> not to produce warning messages when

questionable parallel instructions are encountered.



     <br><dt><code>-Wnp</code>

     <dd>This is a shorter synonym for the <em>-no-warn-explicit-parallel-conflicts</em>

option.
