<div name="messageBodySection" style="font-size: 14px; font-family: -apple-system, BlinkMacSystemFont, sans-serif;">Well, you can call function pass on demand in a module pass like <span style="color: rgb(36, 39, 41); font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, sans-serif; font-size: 13px; font-variant-ligatures: normal; orphans: 2; white-space: pre-wrap; widows: 2; background-color: rgb(239, 240, 241);">getAnalysis<LoopInfoWrapperPass>(f). Not something for AA?</span></div>

<div>Ashutosh once asked the same question, and later said:</div>
<div>
<pre style="white-space: pre-wrap; font-variant-ligatures: normal; orphans: 2; widows: 2;">
'createLegacyPMAAResults' can help here.
</pre>
<pre style="white-space: pre-wrap; font-variant-ligatures: normal; orphans: 2; widows: 2;">
But how should this be used to solve the assertion problem?

<br />
The problem is that you can't require a FunctionPass from a ModulePass. The solution is not to do that.<br />
<br />
createLegacyPMAAResults is an alternative way to access alias analysis without an AAResultsWrapperPass. See the LLVM source code for examples of how to use it.<br />
