Member Function Documentation

void ELFCodeEmitter::startFunction

(

MachineFunction &

F

)

[virtual]

startFunction - This callback is invoked when a new machine function is about to be emitted.

Implements llvm::MachineCodeEmitter.

Definition at line 134 of file ELFWriter.cpp.

bool ELFCodeEmitter::finishFunction

(

MachineFunction &

F

)

[virtual]

finishFunction - This callback is invoked after the function is completely finished.

Implements llvm::MachineCodeEmitter.

Definition at line 161 of file ELFWriter.cpp.

void llvm::ELFCodeEmitter::addRelocation

(

const MachineRelocation &

MR

)

[inline, virtual]

addRelocation - Whenever a relocatable address is needed, it should be noted with this interface.

Implements llvm::MachineCodeEmitter.

Definition at line 82 of file ELFWriter.cpp.

virtual void llvm::ELFCodeEmitter::StartMachineBasicBlock

(

MachineBasicBlock *

MBB

)

[inline, virtual]

StartMachineBasicBlock - This should be called by the target when a new basic block is about to be emitted. This way the MCE knows where the start of the block is, and can implement getMachineBasicBlockAddress.

Implements llvm::MachineCodeEmitter.

Definition at line 86 of file ELFWriter.cpp.

virtual uintptr_t llvm::ELFCodeEmitter::getConstantPoolEntryAddress

(

unsigned

Index

)

const [inline, virtual]

FIXME: These should all be handled with relocations!

getConstantPoolEntryAddress - Return the address of the 'Index' entry in the constant pool that was last emitted with the emitConstantPool method.

Implements llvm::MachineCodeEmitter.

Definition at line 89 of file ELFWriter.cpp.

virtual uintptr_t llvm::ELFCodeEmitter::getJumpTableEntryAddress

(

unsigned

Index

)

const [inline, virtual]

getJumpTableEntryAddress - Return the address of the jump table with index 'Index' in the function that last called initJumpTableInfo.

Implements llvm::MachineCodeEmitter.

Definition at line 93 of file ELFWriter.cpp.

virtual uintptr_t llvm::ELFCodeEmitter::getMachineBasicBlockAddress

(

MachineBasicBlock *

MBB

)

const [inline, virtual]

getMachineBasicBlockAddress - Return the address of the specified MachineBasicBlock, only usable after the label for the MBB has been emitted.

Implements llvm::MachineCodeEmitter.

Definition at line 98 of file ELFWriter.cpp.

virtual uintptr_t llvm::ELFCodeEmitter::getLabelAddress

(

uint64_t

LabelID

)

const [inline, virtual]

getLabelAddress - Return the address of the specified LabelID, only usable after the LabelID has been emitted.

Implements llvm::MachineCodeEmitter.

Definition at line 103 of file ELFWriter.cpp.

virtual void llvm::ELFCodeEmitter::emitLabel

(

uint64_t

LabelID

)

[inline, virtual]

emitLabel - Emits a label

Implements llvm::MachineCodeEmitter.

Definition at line 109 of file ELFWriter.cpp.

virtual void llvm::ELFCodeEmitter::setModuleInfo

(

llvm::MachineModuleInfo *

Info

)

[inline, virtual]

Specifies the MachineModuleInfo object. This is used for exception handling purposes.

Implements llvm::MachineCodeEmitter.

Definition at line 115 of file ELFWriter.cpp.

void llvm::ELFCodeEmitter::startGVStub	(	const GlobalValue *	F,
		unsigned	StubSize,
		unsigned	Alignment = 1
	)			[inline, virtual]

JIT SPECIFIC FUNCTIONS - DO NOT IMPLEMENT THESE HERE!

Implements llvm::MachineCodeEmitter.

Definition at line 119 of file ELFWriter.cpp.

void* llvm::ELFCodeEmitter::finishGVStub

(

const GlobalValue *

F

)

[inline, virtual]

finishGVStub - This callback is invoked to terminate a GV stub.

Implements llvm::MachineCodeEmitter.

Definition at line 124 of file ELFWriter.cpp.
