| |
| <p>The following example is a complete linker script. It tells the linker |
| to read all of the sections from file <samp><span class="file">all.o</span></samp> and place them at the |
| start of output section ‘<samp><span class="samp">outputa</span></samp>’ which starts at location |
| ‘<samp><span class="samp">0x10000</span></samp>’. All of section ‘<samp><span class="samp">.input1</span></samp>’ from file <samp><span class="file">foo.o</span></samp> |
| follows immediately, in the same output section. All of section |
| ‘<samp><span class="samp">.input2</span></samp>’ from <samp><span class="file">foo.o</span></samp> goes into output section |
| ‘<samp><span class="samp">outputb</span></samp>’, followed by section ‘<samp><span class="samp">.input1</span></samp>’ from <samp><span class="file">foo1.o</span></samp>. |
| All of the remaining ‘<samp><span class="samp">.input1</span></samp>’ and ‘<samp><span class="samp">.input2</span></samp>’ sections from any |
| files are written to output section ‘<samp><span class="samp">outputc</span></samp>’. |
| |
| <pre class="smallexample"> SECTIONS { |
| outputa 0x10000 : |
| { |
| all.o |
| foo.o (.input1) |
| } |
| outputb : |
| { |
| foo.o (.input2) |
| foo1.o (.input1) |
| } |
| outputc : |
| { |
| *(.input1) |
| *(.input2) |
| } |
| } |
| </pre> |
| <p>If an output section's name is the same as the input section's name |
| and is representable as a C identifier, then the linker will |
| automatically see <a href="PROVIDE.html#PROVIDE">PROVIDE</a> two symbols: __start_SECNAME and |
| __stop_SECNAME, where SECNAME is the name of the section. These |
| indicate the start address and end address of the output section |
| respectively. Note: most section names are not representable as |
| C identifiers because they contain a ‘<samp><span class="samp">.</span></samp>’ character. |
