<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m current using LLVM 2.5 to JIT code in a event
driven language running on a game engine. Haven’t updated to 2.7
yet, but I do intend to.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When checking for memory leaks I found that each time I was
calling <span style='font-family:"Courier New"'>EE->runFunction</span> after
creating a stub function to execute an event, all the pass information was being
repeatedly added to <span style='font-family:"Courier New"'>PMDataManager</span><span
style='font-size:10.0pt;font-family:"Courier New"'>.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'><o:p> </o:p></span></p>
<p class=MsoNormal>I have changed <span style='font-family:"Courier New"'>addAnalysisImplsPair</span>
to the following, which seems to have no side effects with what I am doing.
Prior to that, <span style='font-family:"Courier New"'>AnalysisImpls</span> contained
thousands of entries and each time the vector gets realloced to accommodate more
entries we lose a bigger chunk of memory.<o:p></o:p></p>
