<div>Thanks John!</div><div><br></div>I think if I would have an option to use DSA with AA interface, I would have definitely used it. DSA looks like good/precise alias analysis. I believe somewhere in the future someone will work on integrating precise alias analysis with already very powerful tool. That someone may be me if required for our project :) !<div>

Dear All,

<div>I am trying to use DataStructure Alias Analysis. From the
code at poolalloc it seems that rDSA needs to be compiled to get
-ds-aa feature while the Makefile builds just the DSA. <br>

I seem to recall replying to this, but my email client says I
didn't, so I'm responding again.<br>
:)<br>

The rDSA code is some experimental code that we abandoned. We
removed the -ds-aa pass in mainline poolalloc because we weren't
maintaining it and, to the best of our knowledge, no one was using
it.<br>
<br>
Someone sent a patch (I think to the mailing list, but potentially
just to me) that resurrected the -ds-aa pass for DSA with LLVM 2.9
(note that we don't support LLVM 2.9; I think this person just got
it to work on his own since LLVM 2.9 and LLVM 3.0 were pretty
similar at the time). I didn't integrate it as I didn't have time
to review it, and it contains other stuff besides the -ds-aa change.<br>
<br>
Just out of curiosity, are people interested in using DSA via the
AliasAnalysis interface?<br>
