|

|
|
The ‘<samp><span class="samp">org.gnu.gdb.mips.cpu</span></samp>’ feature is required for <acronym>MIPS</acronym> targets.
|
||
|
|
It should contain registers ‘<samp><span class="samp">r0</span></samp>’ through ‘<samp><span class="samp">r31</span></samp>’, ‘<samp><span class="samp">lo</span></samp>’,
|
||
|
|
‘<samp><span class="samp">hi</span></samp>’, and ‘<samp><span class="samp">pc</span></samp>’. They may be 32-bit or 64-bit depending
|
||
|
|
on the target.
|
||
|
|
|
||
|
|
<p>The ‘<samp><span class="samp">org.gnu.gdb.mips.cp0</span></samp>’ feature is also required. It should
|
||
|
|
contain at least the ‘<samp><span class="samp">status</span></samp>’, ‘<samp><span class="samp">badvaddr</span></samp>’, and ‘<samp><span class="samp">cause</span></samp>’
|
||
|
|
registers. They may be 32-bit or 64-bit depending on the target.
|
||
|
|
|
||
|
|
<p>The ‘<samp><span class="samp">org.gnu.gdb.mips.fpu</span></samp>’ feature is currently required, though
|
||
|
|
it may be optional in a future version of <span class="sc">gdb</span>. It should
|
||
|
|
contain registers ‘<samp><span class="samp">f0</span></samp>’ through ‘<samp><span class="samp">f31</span></samp>’, ‘<samp><span class="samp">fcsr</span></samp>’, and
|
||
|
|
‘<samp><span class="samp">fir</span></samp>’. They may be 32-bit or 64-bit depending on the target.
|
||
|
|
|
||
|
|
<p>The ‘<samp><span class="samp">org.gnu.gdb.mips.dsp</span></samp>’ feature is optional. It should
|
||
|
|
contain registers ‘<samp><span class="samp">hi1</span></samp>’ through ‘<samp><span class="samp">hi3</span></samp>’, ‘<samp><span class="samp">lo1</span></samp>’ through
|
||
|
|
‘<samp><span class="samp">lo3</span></samp>’, and ‘<samp><span class="samp">dspctl</span></samp>’. The ‘<samp><span class="samp">dspctl</span></samp>’ register should
|
||
|
|
be 32-bit and the rest may be 32-bit or 64-bit depending on the target.
|
||
|
|
|
||
|
|
<p>The ‘<samp><span class="samp">org.gnu.gdb.mips.linux</span></samp>’ feature is optional. It should
|
||
|
|
contain a single register, ‘<samp><span class="samp">restart</span></samp>’, which is used by the
|
||
|
|
Linux kernel to control restartable syscalls.
