| |
| <p>When <small>GDB</small> 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> |
| <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> |
| <p>For POWER7 processors, <small>GDB</small> provides a set of pseudo-registers, the 64-bit |
| wide Extended Floating Point Registers (‘<samp>f32</samp>’ through ‘<samp>f63</samp>’). |
