Yes, it's enough to have "vanilla clang/LLVM" for parsing OpenMP
code.<br>
But you have to porovide proper driver options to parse OpenMP
nodes. In your case these options are (for clang built from
trunk):<br>
<br>
clang -c -Xclang -ast-dump -Xclang -fopenmp=libiomp5
<FileName><br>
<br>
Try this.<br>

<div>Yes,you are right. I am not getting the <span

</span></div>
<div><span style="font-size:13px">I tried printing out the AST

omp.h header file included, it throws an error. Now I dug
around a little bit more, and have a couple of questions.
Based on what I see here-<a moz-do-not-send="true"

you seem to be the right person to ask. Hope you do not mind.</div>
<div><br>
</div>
<div>I have build llvm from trunk(version 3.6.0). Now to parse
nodes, is the normal vanilla llvm enough or do I need to make
any omp specific changes/build(like <a moz-do-not-send="true"
href="http://clang-omp.github.io/%29">http://clang-omp.github.io/)</a>??</div>
<div><br>
</div>
<div>p.s. My llvm build is fine for all other purposes. i have
been using it for a source-to-source compiler with libtooling
and I have been running the tool on NAS benchmarks(OpenMP
NPB-C version). The only issue I am seeing is with openMP
pragmas.So what I am trying to say is that the llvm build
works fine for other cases and it is tested.</div>

<div>Hi,<br>
are you sure that you have OMPThreadPrivateDecl nodes at
all? Check that the code is compiled with -Xclang
-fopenmp=libiomp5 option.<br>

<div>What I am doing now is using ASTMatcher to

this does not work.</div>

<div>Alternatively I tried with <span

<div> Can anyone point out how I can access the
