Constructor & Destructor Documentation

LICM::LICM (   )  [inline]
 

Definition at line 68 of file LICM.cpp.

Member Function Documentation

bool LICM::doFinalization (   )  [inline, virtual]
 

Reimplemented from llvm::LoopPass.

Definition at line 86 of file LICM.cpp.

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

This transformation requires natural loop information & requires that loop preheaders be inserted into the CFG...

Reimplemented from llvm::Pass.

Definition at line 75 of file LICM.cpp.

References llvm::AnalysisUsage::addPreserved(), llvm::AnalysisUsage::addRequired(), llvm::AnalysisUsage::addRequiredID(), llvm::LoopSimplifyID, and llvm::AnalysisUsage::setPreservesCFG().

bool LICM::runOnLoop (  Loop *  L,
LPPassManager &  LPM
)  [virtual]
 

Hoist expressions out of the specified loop. Note, alias info for inner loop is not preserved so it is not a good idea to run LICM multiple times on one loop.

Implements llvm::LoopPass.

Definition at line 230 of file LICM.cpp.
