the control of the GDB remote debugging stub.

<p><samp>-msoft-float</samp> changes the calling convention in the output file;
|
||
|
|
therefore, it is only useful if you compile <em>all</em> of a program with
|
||
|
|
this option. In particular, you need to compile <samp>libgcc.a</samp>, the
|
||
|
|
library that comes with GCC, with <samp>-msoft-float</samp> in order for
|
||
|
|
this to work.

|

|

<p>Set the instruction set, register set, and instruction scheduling parameters

for machine type <var>cpu_type</var>. Supported values for <var>cpu_type</var> are
|
||
|

‘<samp>mcm</samp>’, ‘<samp>gr5</samp>’ and ‘<samp>gr6</samp>’.
|
||

</p>
|

|
|
<p>‘<samp>mcm</samp>’ is a synonym of ‘<samp>gr5</samp>’ present for backward compatibility.
|

</p>
|

|
|
<p>By default (unless configured otherwise), GCC generates code for the GR5
|
||
|
|
variant of the Visium architecture.
|
||
|
|
</p>
|
||
|
|
<p>With <samp>-mcpu=gr6</samp>, GCC generates code for the GR6 variant of the Visium
|
||
|
|
architecture. The only difference from GR5 code is that the compiler will
|
||
|
|
generate block move instructions.

<dt><code>-muser-mode</code></dt>

<p>Generate code for the user mode, where the access to some general registers

is forbidden: on the GR5, registers r24 to r31 cannot be accessed in this

|
|
mode; on the GR6, only registers r29 to r31 are affected.
