| When <span class="sc">gdb</span> is debugging the PowerPC architecture, it provides a set of |
| pseudo-registers to enable inspection of 128-bit wide Decimal Floating Point |
| numbers stored in the floating point registers. These values must be stored |
| in two consecutive registers, always starting at an even register like |
| <code>f0</code> or <code>f2</code>. |
| |
| <p>The pseudo-registers go from <code>$dl0</code> through <code>$dl15</code>, and are formed |
| by joining the even/odd register pairs <code>f0</code> and <code>f1</code> for <code>$dl0</code>, |
| <code>f2</code> and <code>f3</code> for <code>$dl1</code> and so on. |
| |
| <p>For POWER7 processors, <span class="sc">gdb</span> provides a set of pseudo-registers, the 64-bit |
| wide Extended Floating Point Registers (‘<samp><span class="samp">f32</span></samp>’ through ‘<samp><span class="samp">f63</span></samp>’). |
