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::AMDGPUTargetMachine, llvm::XCoreTargetMachine, llvm::MipsTargetMachine, and llvm::ARMBaseTargetMachine.

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.

	)

virtual

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.

virtual

addPassesToEmitMC - Add passes to the specified pass manager to get machine code emitted with the MCJIT. This method returns true if machine code is not supported. It fills the MCContext Ctx pointer which can be used to build custom MCStreamer.
