bool X86TargetMachine::addPassesToEmitMachineCode ( FunctionPassManager PM,
MachineCodeEmitter MCE 
) [virtual]

addPassesToEmitMachineCode - Add passes to the specified pass manager to get machine code emitted. This uses a MachineCodeEmitter object to handle actually outputting the machine code and resolving things like the address of functions. This method should returns true if machine code emission is not supported.

virtual TargetJITInfo* llvm::X86TargetMachine::getJITInfo (  )  [inline, virtual]

getJITInfo - If this target supports a JIT, return information for it, otherwise return null.

Reimplemented from llvm::TargetMachine.

Definition at line 39 of file X86TargetMachine.h.

unsigned X86TargetMachine::getJITMatchQuality (  )  [static]

getJITMatchQuality - This static method should be implemented by targets that provide JIT capabilities to indicate how suitable they are for execution on the current host. If a value of 0 is returned, the target will not be used unless an explicit -march option is used.

Reimplemented from llvm::TargetMachine.

unsigned X86TargetMachine::getModuleMatchQuality ( const Module M  )  [static]

getModuleMatchQuality - This static method should be implemented by targets to indicate how closely they match the specified module. This is used by the LLC tool to determine which target to use when an explicit -march option is not specified. If a target returns zero, it will never be chosen without an explicit -march option.

Reimplemented from llvm::TargetMachine.

virtual const MRegisterInfo* llvm::X86TargetMachine::getRegisterInfo (  )  const [inline, virtual]

getRegisterInfo - If register information is available, return it. If not, return null. This is kept separate from RegInfo until RegInfo has details of graph coloring register allocation removed from it.

virtual const TargetSubtarget* llvm::X86TargetMachine::getSubtargetImpl (  )  const [inline, virtual]

getSubtargetImpl - virtual method implemented by subclasses that returns a reference to that target's TargetSubtarget-derived member variable.
