class LegacyDivergenceAnalysis

Declaration

class LegacyDivergenceAnalysis : public FunctionPass { /* full declaration omitted */ };

Description

FunctionPass class - This class is used to implement most global optimizations. Optimizations should subclass this class if they meet the following constraints: 1. Optimizations are organized globally, i.e., a function at a time 2. Optimizing a function does not cause the addition or removal of any functions in the module

Methods

¶LegacyDivergenceAnalysis()

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:30

¶void getAnalysisUsage(
    llvm::AnalysisUsage& AU) const

Description

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.

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:32

Parameters

llvm::AnalysisUsage& AU

¶bool isDivergent(const llvm::Value* V) const

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:40

Parameters

const llvm::Value* V

¶bool isDivergentUse(const llvm::Use* U) const

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:43

Parameters

const llvm::Use* U

¶bool isUniform(const llvm::Value* V) const

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:46

Parameters

const llvm::Value* V

¶bool isUniformUse(const llvm::Use* U) const

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:50

Parameters

const llvm::Use* U

¶void print(llvm::raw_ostream& OS,
           const llvm::Module*) const

Description

print - Print out the internal state of the pass. This is called by Analyze to print out the contents of an analysis. Otherwise it is not necessary to implement this method. Beware that the module pointer MAY be null. This automatically forwards to a virtual function that does not provide the Module* in case the analysis doesn't need it it can just be ignored.

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:37

Parameters

llvm::raw_ostream& OS

const llvm::Module*

¶void removeValue(const llvm::Value* V)

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:53

Parameters

const llvm::Value* V

¶bool runOnFunction(llvm::Function& F)

Description

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

Declared at: llvm/include/llvm/Analysis/LegacyDivergenceAnalysis.h:34

Parameters

llvm::Function& F
