The linkerscript is an external file that allows the user to specify the order
|
||||
of sections without the need for doing so before assembling each object file.
|
||||
<div class="Pp"></div>
|
||||
The placement of sections specified in the linkerscript is done before the
|
||||
sections whose placement is defined in the source code.
|
||||
<div class="Pp"></div>
|
||||
A linkerscript consists on a series of banks followed by a list of sections and,
|
||||
optionally, commands. They can be lowercase or uppercase, it is ignored. Any
|
||||
line can contain a comment starting with
|
||||
‘<code class="Li">;</code>’ that ends at the end of the line:
|
||||

Numbers can be in decimal or hexadecimal format (the prefix is
|
||||
‘<code class="Li">$</code>’). It is an error if any section name
|
||||
or command are found before setting a bank.
|
||||
<div class="Pp"></div>
|
||||
Files can be included by using the <var class="Ar" title="Ar">INCLUDE</var>
|
||||
keyword followed by a string with the path of the file that has to be
|
||||
included.
|
||||
<div class="Pp"></div>
|
||||
The possible bank types are: <b class="Sy" title="Sy">ROM0</b>,
|
||||
<b class="Sy" title="Sy">ROMX</b>, <b class="Sy" title="Sy">VRAM</b>,
|
||||
<b class="Sy" title="Sy">WRAM0</b>, <b class="Sy" title="Sy">WRAMX</b>,
|
||||
<b class="Sy" title="Sy">OAM</b> and <b class="Sy" title="Sy">HRAM</b>. Types
|
||||
<b class="Sy" title="Sy">ROMX</b>, <b class="Sy" title="Sy">VRAM</b>,
|
||||
<b class="Sy" title="Sy">WRAMX</b> and <b class="Sy" title="Sy">SRAM</b> are
|
||||
banked, which means that it is needed to specify a bank after the type.
|
||||
<div class="Pp"></div>
|
||||
When a new bank statement is found, sections found after it will be placed right
|
||||
from the beginning of that bank. If the linkerscript switches to a different
|
||||
bank and then it comes back to the previous one it will continue from the last
|
||||
address that was used.
|
||||
<div class="Pp"></div>
|
||||
The only two commands are <var class="Ar" title="Ar">ORG</var> and

<var class="Ar" title="Ar">ALIGN</var>:

Note: The bank, alignment, address and type of sections can be specified both in
|
||||
the source code and in the linkerscript. For a section to be able to be placed
|
||||
with the linkerscript the bank must be left unassigned in the source code or
|
||||
be the same as the one specified in the linkerscript. The address and
|
||||
alignment musn't be set.
