Methods

¶MachineJumpTableInfo(
    llvm::MachineJumpTableInfo::JTEntryKind Kind)

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:82

Parameters

llvm::MachineJumpTableInfo::JTEntryKind Kind

¶void RemoveJumpTable(unsigned int Idx)

Description

RemoveJumpTable - Mark the specific index as being dead. This will prevent it from being emitted.

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:105

Parameters

unsigned int Idx

¶bool ReplaceMBBInJumpTable(
    unsigned int Idx,
    llvm::MachineBasicBlock* Old,
    llvm::MachineBasicBlock* New)

Description

ReplaceMBBInJumpTable - If Old is a target of the jump tables, update the jump table to branch to New instead.

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:115

Parameters

unsigned int Idx

llvm::MachineBasicBlock* Old

llvm::MachineBasicBlock* New

¶bool ReplaceMBBInJumpTables(
    llvm::MachineBasicBlock* Old,
    llvm::MachineBasicBlock* New)

Description

ReplaceMBBInJumpTables - If Old is the target of any jump tables, update the jump tables to branch to New instead.

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:111

Parameters

llvm::MachineBasicBlock* Old

llvm::MachineBasicBlock* New

¶unsigned int createJumpTableIndex(
    const std::vector<MachineBasicBlock*>&
        DestBBs)

Description

createJumpTableIndex - Create a new jump table.

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:93

Parameters

const std::vector<MachineBasicBlock*>& DestBBs

¶void dump() const

Description

dump - Call to stderr.

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:125

¶unsigned int getEntryAlignment(
    const llvm::DataLayout& TD) const

Description

getEntryAlignment - Return the alignment of each entry in the jump table.

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:89

Parameters

const llvm::DataLayout& TD

¶llvm::MachineJumpTableInfo::JTEntryKind
getEntryKind() const

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:84

¶unsigned int getEntrySize(
    const llvm::DataLayout& TD) const

Description

getEntrySize - Return the size of each entry in the jump table.

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:87

Parameters

const llvm::DataLayout& TD

¶const std::vector<MachineJumpTableEntry>&
getJumpTables() const

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:99

¶bool isEmpty() const

Description

isEmpty - Return true if there are no jump tables.

Declared at: llvm/include/llvm/CodeGen/MachineJumpTableInfo.h:97

¶void print(llvm::raw_ostream& OS) const

Description

print - Used by the MachineFunction printer to print information about jump tables. Implemented in MachineFunction.cpp
