Hi, I solved it. From the <code>ConstantStruct</code> you can call getOperand() multiple times, so "mine" as deep as you can. <br><br><div class="gmail_quote">On Fri, Mar 1, 2013 at 1:41 PM, Alexandru Ionut Diaconescu <span dir="ltr"><<a href="mailto:alexandruionutdiaconescu@gmail.com" target="_blank">alexandruionutdiaconescu@gmail.com</a>></span> wrote:<br>

I cast the entire annotated expression to Value*. Then, in order to avoid ugly things like getAsString(), I check if <code>V->getValueID() == Value::ConstantArrayVal</code> in order to cast it to <code>ConstantArray</code>. Because it contains only array[0], I cast array0>getOperand(0) to <code>ConstantStruct</code>. Therefore, from <code>ConstantStruct</code> you can get all the four operands. Now, as a TODO, is only to get the names of @f, @str from every field.<br>
<br>But right now I have only a small step to do. ConstantStruct->getOperand(0) gives me i8* bitcast (i32* @f to i8*) . Do you know how I can get the name @f from this? I cannot convert it again to ConstantStruct and follow the same procedure, it will give me a segfault. <br>
<br>Thank you again. Your advice was very helpful :)<div class="HOEnZb"><div class="h5"><br><br><br><div class="gmail_quote">On Fri, Mar 1, 2013 at 9:22 AM, Sebastian Dreßler <span dir="ltr"><<a href="mailto:dressler@zib.de" target="_blank">dressler@zib.de</a>></span> wrote:<br>

</div>This is an Array Type (<a href="http://llvm.org/docs/LangRef.html#array-type" target="_blank">http://llvm.org/docs/LangRef.html#array-type</a>)<br>
which contains a struct. I assume, that you could cast to ConstantArray<br>
which is a Value and then use getOperand(0) and cast its result to<br>
ConstantStruct, like I've done in the sample code. Then you have the<br>
struct and you can traverse it further.<br>
<br>
<br>
