void MachOCodeEmitter::emitConstantPool

(

MachineConstantPool *

MCP

)

emitConstantPool - For each constant pool entry, figure out which section the constant should live in, allocate space for it, and emit it to the Section data buffer.

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

Implements llvm::MachineCodeEmitter.

virtual void llvm::MachOCodeEmitter::StartMachineBasicBlock

(

MachineBasicBlock *
