void LLVMTargetMachine::addAnalysisPasses

PassManagerBase &

PM

)

[virtual]

Register analysis passes for this target with a pass manager.

This registers target independent analysis passes.

Reimplemented from llvm::TargetMachine.

Reimplemented in llvm::PPCTargetMachine, llvm::X86TargetMachine, llvm::ARMBaseTargetMachine, and llvm::MipsTargetMachine.

virtual bool llvm::LLVMTargetMachine::addCodeEmitter	(	PassManagerBase &	,
		JITCodeEmitter &
	)		[inline, virtual]

addCodeEmitter - This pass should be overridden by the target to add a code emitter, if supported. If this is not supported, 'true' should be returned.

addPassesToEmitFile - Add passes to the specified pass manager to get the specified file emitted. Typically this will involve several steps of code generation.

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