<div>the location of the function declaration/definition appears to be easier to construct and would work fine for me.</div>

<div>What's your "key" for the overload of bar in this case?</div>
<div>Possible keys:</div>

Dear all,<br>
<br>
I would like to use the clang infrastructure (libclang, libtooling, ...) to find all references to a function overload or a type in a program. This should also work if the program has templates.<br>
<br>
Consider the following example:<br>
<br>
void f(int i)<br>
{}<br>
<br>
template <typename T><br>
void f(T x)<br>
{<br>
X<T> y;<br>
}<br>
<br>
template <typename T><br>
struct X<br>
{};<br>
<br>
template <><br>
struct X<long><br>
{};<br>
<br>
main ()<br>
{<br>
f(3.0);<br>
f(1);<br>
f(1l);<br>
<br>
return 0;<br>
}<br>
<br>
For example, I would like to find all occurences of the overload "void f(int i)" (result should be the line with "f(1)" or all occurences of the specialization "X<long>" (in the line with "X<T> y" when f is called with a long value.<br>
<br>
Is this possible with clang? If so, can anyone point me in the right direction?<br>
</blockquote>

</div>
<div>Yes. Start here: <a href="http://clang.llvm.org/docs/Tooling.html" target="_blank">http://clang.llvm.org/docs/Tooling.html</a></div>
