But debugging clang generated executables with gdb should or will
be possible (on AIX)?<br>

<font color="#1D1C1D">Hi，<br>
<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].<br>
<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. <br>
<br>
So we are considering doing some compatibly work in
clang/llvm to help improving user experience.<br>
<br>
There are some limitations in dbx we know so far:</font>
<ul>
<ul>
<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>
</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.<br>
<br>
Any thoughts about the direction here? Reviews and
feedback to [3][4] are also appreciated.</font><font
