<p class="MsoNormal">Yes, we are interested in the gdb side of things too – as Sourabh said, we have been following Ali’s patches. I think we will co-ordinate with Ali to see what gdb support for DWARF5 we can add so that we don’t tread on each other’s toes.

<br>
I work at Google & we're certainly interested in DWARFv5 compliance - I'm currently working on improving debug_loclist emission to share more address pool entries ( <a href="https://reviews.llvm.org/D68620">https://reviews.llvm.org/D68620</a> ) which includes
some improvements to llvm-dwarfdump to go with that. (Pavel's working on further improvements <a href="https://reviews.llvm.org/D68271">https://reviews.llvm.org/D68271</a> )<br>
<br>
I haven't looked at/started on the loclist issue (PR43622) - so if you want to look at that, that's fine by me.<br>
<br>
Are you also interested in the debugger side of things? GDB's DWARFv5 support is pretty incomplete & Ali's already looking at some of that, and I might get to the debug_loclist improvements necessary - but if someone else wants to do that before me, I won't
complain.<br>
<br>
Not sure of any other major holes in LLVM's DWARFv5 support, but they might be out there, for sure.<o:p></o:p></p>
