Detailed Description

SCCP Class - This class uses the SCCPSolver to implement a per-function Sparse Conditional Constant Propagator.

Definition at line 1498 of file SCCP.cpp.

Constructor & Destructor Documentation

SCCP::SCCP (   )  [inline]
 

Definition at line 1500 of file SCCP.cpp.

Member Function Documentation

virtual void SCCP::getAnalysisUsage (  AnalysisUsage &  AU  )  const [inline, virtual]
 

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 1507 of file SCCP.cpp.

References llvm::AnalysisUsage::setPreservesCFG().

bool SCCP::runOnFunction (  Function &  F  )  [virtual]
 

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

Implements llvm::FunctionPass.
