<p><a name="index-integer-notation-456"></a><a name="index-constants-in-linker-scripts-457"></a>All constants are integers.
|
||
|
|
|
||
|
|
<p>As in C, the linker considers an integer beginning with <span class="samp">0</span> to be
|
||
|
|
octal, and an integer beginning with <span class="samp">0x</span> or <span class="samp">0X</span> to be
|
||
|
|
hexadecimal. The linker considers other integers to be decimal.

|

|
constant by

<!-- TEXI2ROFF-KILL -->

<!-- END TEXI2ROFF-KILL -->

respectively. For example, the following all refer to the same quantity:

_fourk_2 = 4096;
