FileModel::Model LLVMTargetMachine::addPassesToEmitFile	(	PassManagerBase &	PM,
		raw_ostream &	Out,
		CodeGenFileType	FileType,
		bool	Fast
	)			[virtual]

addPassesToEmitFile - Add passes to the specified pass manager to get the specified file emitted. Typically this will involve several steps of code generation. If Fast is set to true, the code generator should emit code as fast as possible, though the generated code may be less efficient. This method should return FileModel::Error if emission of this file type is not supported.

The default implementation of this method adds components from the LLVM retargetable code generator, invoking the methods below to get target-specific passes in standard locations.

	)			[virtual]

addPassesToEmitFileFinish - If the passes to emit the specified file had to be split up (e.g., to add an object writer pass), this method can be used to finish up adding passes to emit the file, if necessary.

	)			[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 returns true if machine code emission is not supported.

virtual bool llvm::LLVMTargetMachine::addInstSelector	(	PassManagerBase &	,

	)			[inline, virtual]

Target-Independent Code Generator Pass Configuration Options.

addInstSelector - This method should add any "last minute" LLVM->LLVM passes, then install an instruction selector pass, which converts from LLVM code to machine instructions.

addPreRegAllocPasses - This method may be implemented by targets that want to run passes immediately before register allocation. This should return true if -print-machineinstrs should print after these passes.

addPostRegAllocPasses - This method may be implemented by targets that want to run passes after register allocation but before prolog-epilog insertion. This should return true if -print-machineinstrs should print after these passes.

addAssemblyEmitter - This pass should be overridden by the target to add the asmprinter, if asm emission is supported. If this is not supported, 'true' should be returned.
