  72. 

  73. <p>The &lsquo;<samp>org.gnu.gdb.nds32.core</samp>&rsquo; feature is required for NDS32

  74. targets.  It should contain at least registers &lsquo;<samp>r0</samp>&rsquo; through

  75. &lsquo;<samp>r10</samp>&rsquo;, &lsquo;<samp>r15</samp>&rsquo;, &lsquo;<samp>fp</samp>&rsquo;, &lsquo;<samp>gp</samp>&rsquo;, &lsquo;<samp>lp</samp>&rsquo;, &lsquo;<samp>sp</samp>&rsquo;,

  76. and &lsquo;<samp>pc</samp>&rsquo;.

  77. </p>

  78. <p>The &lsquo;<samp>org.gnu.gdb.nds32.fpu</samp>&rsquo; feature is optional.  If present,

  79. it should contain 64-bit double-precision floating-point registers

  80. &lsquo;<samp>fd0</samp>&rsquo; through <em>fdN</em>, which should be &lsquo;<samp>fd3</samp>&rsquo;, &lsquo;<samp>fd7</samp>&rsquo;,

  81. &lsquo;<samp>fd15</samp>&rsquo;, or &lsquo;<samp>fd31</samp>&rsquo; based on the FPU configuration implemented.

  82. </p>

  83. <p><em>Note:</em> The first sixteen 64-bit double-precision floating-point

  84. registers are overlapped with the thirty-two 32-bit single-precision

  85. floating-point registers.  The 32-bit single-precision registers, if

  86. not being listed explicitly, will be synthesized from halves of the

  87. overlapping 64-bit double-precision registers.  Listing 32-bit

  88. single-precision registers explicitly is deprecated, and the

  89. support to it could be totally removed some day.
