Methods

¶AnalysisUsage()

Declared at: llvm/include/llvm/PassAnalysisSupport.h:58

¶template <class PassClass>
llvm::AnalysisUsage& addPreserved()

Description

Add the specified Pass class to the set of analyses preserved by this pass.

Declared at: llvm/include/llvm/PassAnalysisSupport.h:88

Templates

PassClass

¶llvm::AnalysisUsage& addPreserved(
    llvm::StringRef Arg)

Description

Add the Pass with the specified argument string to the set of analyses preserved by this pass. If no such Pass exists, do nothing. This can be useful when a pass is trivially preserved, but may not be linked in. Be careful about spelling!

Declared at: llvm/include/llvm/PassAnalysisSupport.h:117

Parameters

llvm::StringRef Arg

¶llvm::AnalysisUsage& addPreservedID(
    const void* ID)

Description

@ { Add the specified ID to the set of analyses preserved by this pass.

Declared at: llvm/include/llvm/PassAnalysisSupport.h:78

Parameters

const void* ID

¶llvm::AnalysisUsage& addPreservedID(char& ID)

Declared at: llvm/include/llvm/PassAnalysisSupport.h:82

Parameters

char& ID

¶template <class PassClass>
llvm::AnalysisUsage& addRequired()

Declared at: llvm/include/llvm/PassAnalysisSupport.h:65

Templates

PassClass

¶llvm::AnalysisUsage& addRequiredID(const void* ID)

Description

@ { Add the specified ID to the required set of the usage info for a pass.

Declared at: llvm/include/llvm/PassAnalysisSupport.h:62

Parameters

const void* ID

¶llvm::AnalysisUsage& addRequiredID(char& ID)

Declared at: llvm/include/llvm/PassAnalysisSupport.h:63

Parameters

char& ID

¶template <class PassClass>
llvm::AnalysisUsage& addRequiredTransitive()

Declared at: llvm/include/llvm/PassAnalysisSupport.h:71

Templates

PassClass

¶llvm::AnalysisUsage& addRequiredTransitiveID(
    char& ID)

Declared at: llvm/include/llvm/PassAnalysisSupport.h:69

Parameters

char& ID

¶template <class PassClass>
llvm::AnalysisUsage& addUsedIfAvailable()

Description

Add the specified Pass class to the set of analyses used by this pass.

Declared at: llvm/include/llvm/PassAnalysisSupport.h:107

Templates

PassClass

¶llvm::AnalysisUsage& addUsedIfAvailableID(
    char& ID)

Declared at: llvm/include/llvm/PassAnalysisSupport.h:101

Parameters

char& ID

¶llvm::AnalysisUsage& addUsedIfAvailableID(
    const void* ID)

Description

@ { Add the specified ID to the set of analyses used by this pass if they are available..

Declared at: llvm/include/llvm/PassAnalysisSupport.h:97

Parameters

const void* ID

¶const llvm::AnalysisUsage::VectorType&
getPreservedSet() const

Declared at: llvm/include/llvm/PassAnalysisSupport.h:138

¶bool getPreservesAll() const

Description

Determine whether a pass said it does not transform its input at all

Declared at: llvm/include/llvm/PassAnalysisSupport.h:123

¶const llvm::AnalysisUsage::VectorType&
getRequiredSet() const

Declared at: llvm/include/llvm/PassAnalysisSupport.h:134

¶const llvm::AnalysisUsage::VectorType&
getRequiredTransitiveSet() const

Declared at: llvm/include/llvm/PassAnalysisSupport.h:135

¶const llvm::AnalysisUsage::VectorType&
getUsedSet() const

Declared at: llvm/include/llvm/PassAnalysisSupport.h:139

¶void setPreservesAll()

Description

Set by analyses that do not transform their input at all

Declared at: llvm/include/llvm/PassAnalysisSupport.h:120

¶void setPreservesCFG()

Description

This function should be called by the pass, iff they do not: 1. Add or remove basic blocks from the function 2. Modify terminator instructions in any way. This function annotates the AnalysisUsage info object to say that analyses that only depend on the CFG are preserved by this pass.
