<div dir="ltr">Ah, please ignore the above. Skeleton CU looks does not need children for that.<br>

<div dir="ltr">So theoretical scenario I meant was:<br>
<span style="font-size: 12pt;">1) test.o file has:</span><br>
</div>
<div dir="ltr">.debug_info skeleton<br>
</div>
<div dir="ltr">[0..N] .debug_info sections with types<br>
</div>
<div dir="ltr">2) Then test.dwo would have full .debug_info with declarations of types<br>
</div>
<div dir="ltr">which definitions are still in test.o.<br>
</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">I am not sure if it is possible to represent and makes sence. Assuming it is possible,</div>
<div dir="ltr"><span style="font-size: 12pt;">and there is enough duplicate types, that would add some work </span><span style="font-size: 12pt;">f</span><span style="font-size: 12pt;">or linker to deduplicate</span></div>
<div dir="ltr"><span style="font-size: 12pt;">sections, though it should be fast, </span><span style="font-size: 12pt;">a</span><span style="font-size: 12pt;">nd would increase output binary for size of deduplicated types. </span></div>
<div dir="ltr"><span style="font-size: 12pt;">But also would reduce size of whole set (</span><span style="font-size: 12pt;">executable + *.dwo), what can probably be useful.</span></div>
