Detailed Description

A wrapper pass for external alias analyses.

This just squirrels away the callback used to run any analyses and register their results.

Member Function Documentation

◆ getAnalysisUsage()

void llvm::ExternalAAWrapperPass::getAnalysisUsage ( AnalysisUsage ) const
inlineoverridevirtual

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.

If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.

Reimplemented from llvm::Pass.
