Member Function Documentation

◆ getAnalysisUsage()

void LazyValueInfoWrapperPass::getAnalysisUsage ( AnalysisUsage ) const
overridevirtual

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.

Definition at line 1461 of file LazyValueInfo.cpp.

References llvm::AnalysisUsage::addRequired(), and llvm::AnalysisUsage::setPreservesAll().

◆ getLVI()

LazyValueInfo & LazyValueInfoWrapperPass::getLVI ( )

Definition at line 1467 of file LazyValueInfo.cpp.

◆ releaseMemory()

void LazyValueInfoWrapperPass::releaseMemory ( )
overridevirtual

releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed.

The default behavior of passes is to hold onto memory for the entire duration of their lifetime (which is the entire compile time). For pipelined passes, this is not a big deal because that memory gets recycled every time the pass is invoked on another program unit. For IP passes, it is more important to free memory when it is unused.

Optionally implement this function to release pass memory when it is no longer used.

Reimplemented from llvm::Pass.

Definition at line 1491 of file LazyValueInfo.cpp.

◆ runOnFunction()

bool LazyValueInfoWrapperPass::runOnFunction ( Function F)
overridevirtual

runOnFunction - Virtual method overriden by subclasses to do the per-function processing of the pass.

Implements llvm::FunctionPass.
