Hello All:<br><br>
I have a question regarding linker scripts and initialization and
finalization code.<br><br>
The following is a portion of my current linker script:<br><br>
<tt> /*<br>
** Initialization and finalization code.<br>
*/<br>
. = ALIGN (16);<br>
PROVIDE (_init = .);<br>
*crti.o(.init)<br>
*(.init)<br>
*crtn.o(.init)<br>
. = ALIGN (16);<br>
PROVIDE (_fini = .);<br>
*crti.o(.fini)<br>
*(.fini)<br>
*crtn.o(.fini)<br><br>
</tt>And it produces the following listing:<br><br>
<tt>fff15fd0 <_init>:<br>
fff15fd0:<x-tab> </x-tab>4e56
0000 <x-tab> </x-tab>linkw
%fp,#0<br>
fff15fd4:<x-tab> </x-tab>4eb9
fff0 0ac6 <x-tab> </x-tab>jsr fff00ac6 <frame_dummy><br>
fff15fda:<x-tab> </x-tab>4e5e
<x-tab> </x-tab>unlk %fp<br>
fff15fdc:<x-tab> </x-tab>4e75
<x-tab> </x-tab>rts<br>
fff15fde:<x-tab> </x-tab>4eb9
fff0 0b0c <x-tab> </x-tab>jsr fff00b0c
<__do_global_ctors_aux><br>
<x-tab> </x-tab>...<br><br>
fff15ff0 <_fini>:<br>
fff15ff0:<x-tab> </x-tab>4e56
0000 <x-tab> </x-tab>linkw
%fp,#0<br>
fff15ff4:<x-tab> </x-tab>4eb9
fff0 0a70 <x-tab> </x-tab>jsr fff00a70
<__do_global_dtors_aux><br>
fff15ffa:<x-tab> </x-tab>4e5e
<x-tab> </x-tab>unlk %fp<br>
fff15ffc:<x-tab> </x-tab>4e75
<x-tab> </x-tab>rts<br>
<x-tab> </x-tab>...<br><br>
</tt>It seems to me that the jsr fff00b0c <__do_global_ctors_aux>
is unreachable code. Is this correct? If so how do I correct
the problem?<br><br>
Thanks in advance.<br><br>
