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 133 of file ELFWriter.cpp.

| bool ELFCodeEmitter::finishFunction | ( | MachineFunction & | F | ) | [virtual] |
finishFunction - This callback is invoked after the function is completely finished.
Implements llvm::MachineCodeEmitter.

| 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 81 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 85 of file ELFWriter.cpp.
| virtual intptr_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 88 of file ELFWriter.cpp.
| virtual intptr_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 92 of file ELFWriter.cpp.
| virtual intptr_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 97 of file ELFWriter.cpp.
| virtual intptr_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 102 of file ELFWriter.cpp.
| virtual void llvm::ELFCodeEmitter::emitLabel | ( | uint64_t | LabelID | ) | [inline, virtual] |
emitLabel - Emits a label
Implements llvm::MachineCodeEmitter.
Definition at line 108 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 114 of file ELFWriter.cpp.
| void llvm::ELFCodeEmitter::startFunctionStub | ( | const GlobalValue * | F, | |
| unsigned | StubSize, | |||
| unsigned | Alignment = 1 | |||
| ) | [inline, virtual] |
JIT SPECIFIC FUNCTIONS - DO NOT IMPLEMENT THESE HERE!
Implements llvm::MachineCodeEmitter.
Definition at line 118 of file ELFWriter.cpp.
| void* llvm::ELFCodeEmitter::finishFunctionStub | ( | const GlobalValue * | F | ) | [inline, virtual] |
finishFunctionStub - This callback is invoked to terminate a function stub.
Implements llvm::MachineCodeEmitter.
