<div dir="ltr">Static profiling. Trying to implement "Statis Branch Frequency and Program Profile Analysis" by We and Larus, 1994 or some similar algorithm. Attempts to do it as a MachineFunctionPass didn't work out, as type information was lost. It's important to know what's a pointer for the described algorithm.<br>

<div style="">Ok. If it's at llvm ir level, it's very simple since everything is in SSA form. What are you trying to achieve though? <div><br></div><font color="#888888"><div>Evan</div></font><div class="Ih2E3d"><div>

I'd like something at the FunctionPass level.<br>

I am not sure what you mean. Live interval analysis is done at the<br> function level.<br> <br> Evan<br> <div><div></div><div><br> On Aug 19, 2008, at 1:26 AM, Sean Soria wrote:<br> <br> > Is there an equivalent to LiveIntervals that works at the Function<br>
