I wrote a module pass that uses Alias Analysis.<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:left;line-height:normal;direction:ltr;unicode-bidi:embed">
For this reason I added AU.addRequired<AliasAnalysis>() to function getAnalysisUsage and used getAnalysis<AliasAnalysis>() in my pass.<o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:left;line-height:normal;direction:ltr;unicode-bidi:embed">
I tried a few types of alias analyses and I discovered that only alias analyses which are ImmutablePasses are returned using getAnalysis<AliasAnalysis>(). Moreover, when I added both ImmutablePass and FunctionPass, getAnalysis<AliasAnalysis>() returned the
ImmutablePass while the FunctionPass did not even appear in the AA chain ( I assume it is because building the chain uses getAnalysis as well).<o:p></o:p></p>

Does this feature should be supported? <o:p></o:p></p>
