| |
| <p><a name="index-integer-notation-551"></a><a name="index-constants-in-linker-scripts-552"></a>All constants are integers. |
| |
| <p>As in C, the linker considers an integer beginning with ‘<samp><span class="samp">0</span></samp>’ to be |
| octal, and an integer beginning with ‘<samp><span class="samp">0x</span></samp>’ or ‘<samp><span class="samp">0X</span></samp>’ to be |
| hexadecimal. Alternatively the linker accepts suffixes of ‘<samp><span class="samp">h</span></samp>’ or |
| ‘<samp><span class="samp">H</span></samp>’ for hexadecimal, ‘<samp><span class="samp">o</span></samp>’ or ‘<samp><span class="samp">O</span></samp>’ for octal, ‘<samp><span class="samp">b</span></samp>’ or |
| ‘<samp><span class="samp">B</span></samp>’ for binary and ‘<samp><span class="samp">d</span></samp>’ or ‘<samp><span class="samp">D</span></samp>’ for decimal. Any integer |
| value without a prefix or a suffix is considered to be decimal. |
| |
| <p><a name="index-scaled-integers-553"></a><a name="index-K-and-M-integer-suffixes-554"></a><a name="index-M-and-K-integer-suffixes-555"></a><a name="index-suffixes-for-integers-556"></a><a name="index-integer-suffixes-557"></a>In addition, you can use the suffixes <code>K</code> and <code>M</code> to scale a |
| constant by |
| <!-- TEXI2ROFF-KILL --> |
| <!-- END TEXI2ROFF-KILL --> |
| <code>1024</code> or <code>1024*1024</code> |
| <!-- TEXI2ROFF-KILL --> |
| <!-- END TEXI2ROFF-KILL --> |
| respectively. For example, the following |
| all refer to the same quantity: |
| |
| <pre class="smallexample"> _fourk_1 = 4K; |
| _fourk_2 = 4096; |
| _fourk_3 = 0x1000; |
| _fourk_4 = 10000o; |
| </pre> |
| <p>Note - the <code>K</code> and <code>M</code> suffixes cannot be used in |
| conjunction with the base suffixes mentioned above. |
