<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">There are a variety of DWARF types that LLVM doesn't currently support. You've noted a couple from Pascal, sets and subranges as first-class types. Offhand
I know that fixed-point types aren't supported; nor any of the modern FORTRAN types like the fancy array-slicing stuff; nor the more COBOL-specific things like numeric strings and condition-names.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The most active developers on debug-info in LLVM are primarily focused on the languages supported by Clang (C/C++, Objective-C/C++) and Swift. People developing
out-of-tree front ends who want new DWARF or metadata features are pretty much expected to drive the development of those features. If you do that, and can provide adequate tests (either as IR, or as executable unittests calling the APIs directly--not written
in your out-of-tree language), you'll find the reviewers are generally receptive.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Questions on llvm-dev are always appropriate, too, if you run into roadblocks trying to get something to work.<o:p></o:p></span></p>

<div>
<p class="MsoNormal"> Just wondering if there might be support for debugging set types in the future.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">There are a few languages that have an inbuilt set type eg pascal and it would be<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">good to support them. At the moment I'm kludging it with arrays of bits but its less than optimal.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> Also, the DISubrange type is restricted to index types for arrays but it would be good<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">if it could be extended to be a type in its own right to support languages that have<o:p></o:p></p>
