A relocation is made up of the following logical portions: 1. An offset in the machine code buffer, the location to modify. 2. A target specific relocation type (a number from 0 to 63). 3. A symbol being referenced, either as a GlobalValue* or as a string. 4. An optional constant value to be added to the reference. 5. A bit, CanRewrite, which indicates to the JIT that a function stub is not needed for the relocation. 6. An index into the GOT, if the target uses a GOT

bool llvm::MachineRelocation::doesntNeedFunctionStub | ( | ) | const [inline] |
doesntNeedFunctionStub - This function returns true if the JIT for this target is capable of directly handling the relocated instruction without using a stub function. It is always conservatively correct for this flag to be false, but targets can improve their compilation callback functions to handle more general cases if they want improved performance.

unsigned llvm::MachineRelocation::getConstantPoolIndex | ( | ) | const [inline] |
getConstantPoolIndex - If this is a const pool reference, return the index into the constant pool.
Definition at line 155 of file MachineRelocation.h.
References isConstantPoolIndex().
intptr_t llvm::MachineRelocation::getConstantVal | ( | ) | const [inline] |
getConstantVal - Get the constant value associated with this relocation. This is often an offset from the symbol.
Definition at line 102 of file MachineRelocation.h.
GlobalValue* llvm::MachineRelocation::getGlobalValue | ( | ) | const [inline] |
getGlobalValue - If this is a global value reference, return the referenced global.
Definition at line 141 of file MachineRelocation.h.
References isGlobalValue().
unsigned llvm::MachineRelocation::getGOTIndex | ( | ) | const [inline] |
getGOTIndex - Once this has been resolved to an entry in the GOT, this returns that index. The index is from the lowest address entry in the GOT.
Definition at line 180 of file MachineRelocation.h.
unsigned llvm::MachineRelocation::getMachineCodeOffset | ( | ) | const [inline] |
getMachineCodeOffset - Return the offset into the code buffer that the relocation should be performed.
Definition at line 89 of file MachineRelocation.h.
unsigned llvm::MachineRelocation::getRelocationType | ( | ) | const [inline] |
getRelocationType - Return the target-specific relocation ID for this relocation.
Definition at line 95 of file MachineRelocation.h.
void* llvm::MachineRelocation::getResultPointer | ( | ) | const [inline] |
getResultPointer - Once this has been resolved to point to an actual address, this returns the pointer.
Definition at line 162 of file MachineRelocation.h.
const char* llvm::MachineRelocation::getString | ( | ) | const [inline] |
getString - If this is a string value, return the string reference.
Definition at line 148 of file MachineRelocation.h.
References isString().
bool llvm::MachineRelocation::isConstantPoolIndex | ( | ) | const [inline] |
isConstantPoolIndex - Return true if this is a constant pool reference.
Definition at line 120 of file MachineRelocation.h.
Referenced by getConstantPoolIndex(), isGlobalValue(), and isString().
bool llvm::MachineRelocation::isGlobalValue | ( | ) | const [inline] |
isGlobalValue - Return true if this relocation is a GlobalValue, as opposed to a constant string.
Definition at line 108 of file MachineRelocation.h.
References isConstantPoolIndex().
Referenced by getGlobalValue(), and isString().
bool llvm::MachineRelocation::isGOTRelative | ( | ) | const [inline] |
isGOTRelative - Return true the target wants the index into the GOT of the symbol rather than the address of the symbol.
Definition at line 126 of file MachineRelocation.h.
bool llvm::MachineRelocation::isString | ( | ) | const [inline] |
isString - Return true if this is a constant string.

void llvm::MachineRelocation::setGOTIndex | ( | unsigned | idx | ) | [inline] |
setGOTIndex - Set the GOT index to a specific value.
Definition at line 173 of file MachineRelocation.h.
void llvm::MachineRelocation::setResultPointer | ( | void * | Ptr | ) | [inline] |
setResultPointer - Set the result to the specified pointer value.
