Try this for WaveScalar::setLabel:<br>
<br>
- Twine twine(k);<br>
- (*succ)->setName(twine);<br>
+ (*succ)->setName(Twine(k));<br>
<br>
and see whether that makes any difference?<br>

int sum_single_loop (int a){<br>
int su = 0, i;<br>
for (i=0;i<a;i++)<br>

So, you mean to say that the above implementation is correct and<br>
should work fine.<br>
<br>
<br>
So far as I can see - but I could be missing something.<br>
<br>
I initially thought that the above way is not the correct way<br>
anymore since 3.5.0 might have changed few things.<br>
<br>
Anyways here is my dirty code I have written for my research<br>
project that I took the above snippet from :<br>
<br>
<a href="https://github.com/pranavk/spatial-computing/blob/master/waves.cpp#L105" target="_blank">https://github.com/pranavk/<u></u>spatial-computing/blob/master/<u></u>waves.cpp#L105</a><br>
<br>
<br>
Someone (not necessarily me) will presumably need the<br>
input/command/arguments/<u></u>whatever required to trigger the infinite<br>
loop in this code that you're seeing, as well as the code there.<br>
<br>

This may be difficult yo reproduce or debug without a more<br>
complete (though preferably minimal) test case.<br>

I used the above shown function in my pass in LLVM 3.4.2<br>
and it used to work fine but when I am compiling this<br>
pass with 3.5.0, this is a never ending loop. Can<br>
someone please suggest me what can be wrong here ?<br>
<br>
Upon some debugging, I found out that const_iterator I<br>
never becomes equal to IE, rather it goes past IE when<br>
incremented and hence loop never ends.<br>
<br>
Following is the output upon executing above code.<br>
<br>
0x2e08248 <- address of ie<br>
0x2e16630 <- address of I initially<br>
0x2e08250 <- incremented I<br>
0x2e165e0<br>
0x2e16630<br>
0x2e08250<br>
0x2e165e0<br>
0x2e16630<br>
0x2e08250<br>
