class PgmDependenceGraph

Detailed Description

--------------------------------------------------------------------------- class MemoryDepGraph: Dependence analysis for load/store/call instructions using IPModRef info computed at the granularity of individual DSGraph nodes.

This pass computes memory dependences for each function in a module. It can be made a FunctionPass once a Pass (such as Parallelize) is allowed to use a FunctionPass such as this one. ---------------------------------------------------------------------------

Member Function Documentation

void llvm::MemoryDepAnalysis::dump (   )  const
 

Reimplemented from llvm::Pass.

Definition at line 490 of file MemoryDepAnalysis.cpp.

References print().

void llvm::MemoryDepAnalysis::getAnalysisUsage (  AnalysisUsage &  AU  )  const [virtual]
 

getAnalysisUsage - This does not modify anything. It uses the Top-Down DS Graph and IPModRef.

Reimplemented from llvm::Pass.

Definition at line 208 of file MemoryDepAnalysis.cpp.

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

const DependenceGraph& llvm::MemoryDepAnalysis::getGraph (  Function &  F  )  const [inline]
 

Definition at line 77 of file MemoryDepAnalysis.h.

References I.

DependenceGraph& llvm::MemoryDepAnalysis::getGraph (  Function &  F  )  [inline]
 

getGraph - Retrieve the dependence graph for a function. This is temporary and will go away once this is a FunctionPass. At that point, this class should directly inherit from DependenceGraph.
