Thats unfortunate but thx nevertheless.<br>
But debugging clang generated executables with gdb should or will be
possible (on AIX)?<br>

<font color="#1D1C1D">Hi，</font><br>
<font color="#1D1C1D"><br>
As some of you may know [1]，we are working on AIX support.
Part of the AIX support is debug support, supporting dbx as
the consumer of clang DWARF information [2].</font><br>
<font color="#1D1C1D"><br>
While the dbx team is also working on improving its dwarf
support, there are limitations in foreseeable future. Also
there are situations on AIX that end user may not get up to
date debugger. </font><br>
<font color="#1D1C1D"><br>
So we are considering doing some compatibly work in
clang/llvm to help improving user experience.</font><br>
<font color="#1D1C1D"><br>
There are some limitations in dbx we know so far:</font>
<ul>
<ul type="disc">
<li><font face="Monaco" color="#1D1C1D">.dwstr section is
not supported for now;</font></li>
<li><font face="Monaco" color="#1D1C1D">column-info in the
line table not supported for now;</font></li>
<li><font face="Monaco" color="#1D1C1D">sub-optimal
handling of unsupported dwarf tags. Eg: dbx support
dwarf 3, but misbehaving with new DWARF 5 tags
DW_LANG_C_plus_plus_14 [3].</font></li>
</ul>
</ul>
<font color="#1D1C1D"><br>
As discussed with the reviewers in patch [3], we are
considering introducing a new tuning debugger tuning option
for dbx, -debugger-tuning=dbx [4], so that we can change
some option<br>
default on AIX for dbx to accommodate its limitations, eg;
-gno-column-info.</font><br>
<font color="#1D1C1D"><br>
Any thoughts about the direction here? Reviews and feedback
to [3][4] are also appreciated.</font><br>
