There are still serious bugs though and Twobit attached a preliminary patch to that review.<br>
<a href="http://reviews.llvm.org/D4081#52" target="_blank">http://reviews.llvm.org/D4081#<u></u>52</a><br>
<br>
But nothing happened since then.<br>
<br>
I tried to fix it according to rnk's comment "the individual .pdata sections should be comdat associative with the individual .text sections" but don't know enough about the respective llvm internals.<br>
<br>
Could anybody finalize that patch and get this in?<br>
