<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I was wondering if anyone has recommendations on how best to implement Vendor extensions to DWARF support. In particular, some of the functions I need to call are protected methods of the DwarfUnit class
<br>
(such as addAttribute()), but the DwarfCompileUnit subclass is final and can’t be extended, and making a new subclass of DwarfUnit appears to require overriding functions that we don’t need to override. Currently I have added vendor-specific functions to DwarfCompileUnit,
but as we like to keep our extensions separate from proper llvm code, this is less than ideal.<o:p></o:p></p>
