[override, virtual]

Register analysis passes for this target with a pass manager.

This registers target independent analysis passes.

Reimplemented from llvm::TargetMachine.

Reimplemented in llvm::AMDGPUTargetMachine, llvm::AArch64TargetMachine, llvm::PPCTargetMachine, llvm::MipsTargetMachine, llvm::ARMBaseTargetMachine, llvm::final< T >, and llvm::XCoreTargetMachine.

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

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.
