I'm hoping someone here can help me.<br>
<br>
I've just updated to LLVM 3.5.0 and when I run the following I eventually get a crash when I run out of memory.<br>
<br>
opt -O2 bug.ll<br>
<br>
I'll try 3.5.1, then if that's still fails I'll try trunk.<br>
<br>
It seems to be related to the<br>
%5 = fptrunc double %4 to float<br>
