- <a name="index-target-descriptions_002c-MIPS-features"></a>
-
- <p>The ‘<samp>org.gnu.gdb.mips.cpu</samp>’ feature is required for <acronym>MIPS</acronym> targets.
- It should contain registers ‘<samp>r0</samp>’ through ‘<samp>r31</samp>’, ‘<samp>lo</samp>’,
- ‘<samp>hi</samp>’, and ‘<samp>pc</samp>’. They may be 32-bit or 64-bit depending
- on the target.
- </p>
- <p>The ‘<samp>org.gnu.gdb.mips.cp0</samp>’ feature is also required. It should
- contain at least the ‘<samp>status</samp>’, ‘<samp>badvaddr</samp>’, and ‘<samp>cause</samp>’
- registers. They may be 32-bit or 64-bit depending on the target.
- </p>
- <p>The ‘<samp>org.gnu.gdb.mips.fpu</samp>’ feature is currently required, though
- it may be optional in a future version of <small>GDB</small>. It should
- contain registers ‘<samp>f0</samp>’ through ‘<samp>f31</samp>’, ‘<samp>fcsr</samp>’, and
- ‘<samp>fir</samp>’. They may be 32-bit or 64-bit depending on the target.
- </p>
- <p>The ‘<samp>org.gnu.gdb.mips.dsp</samp>’ feature is optional. It should
- contain registers ‘<samp>hi1</samp>’ through ‘<samp>hi3</samp>’, ‘<samp>lo1</samp>’ through
- ‘<samp>lo3</samp>’, and ‘<samp>dspctl</samp>’. The ‘<samp>dspctl</samp>’ register should
- be 32-bit and the rest may be 32-bit or 64-bit depending on the target.
- </p>
- <p>The ‘<samp>org.gnu.gdb.mips.linux</samp>’ feature is optional. It should
- contain a single register, ‘<samp>restart</samp>’, which is used by the
- Linux kernel to control restartable syscalls.
