<h3 class="section">3.10 Expressions in Linker Scripts</h3>
|
|
|
|
<p><a name="index-expressions-454"></a><a name="index-arithmetic-455"></a>The syntax for expressions in the linker script language is identical to
|
|
that of C expressions. All expressions are evaluated as integers. All
|
|
expressions are evaluated in the same size, which is 32 bits if both the
|
|
host and target are 32 bits, and is otherwise 64 bits.
|
|
|
|
<p>You can use and set symbol values in expressions.
|
|
|
|
<p>The linker defines several special purpose builtin functions for use in
|
|
expressions.
