Member Enumeration Documentation

enum llvm::TargetMachine::CodeGenFileType

CodeGenFileType - These enums are meant to be passed into addPassesToEmitFile to indicate what type of file to emit, and returned by it to indicate what type of file could actually be made.

virtual bool llvm::TargetMachine::addPassesToEmitFile ( PassManagerBase &  , formatted_raw_ostream &  , CodeGenFileType  , bool  = true, AnalysisID  = 0, AnalysisID  = 0  )

inlinevirtual

addPassesToEmitFile - Add passes to the specified pass manager to get the specified file emitted. Typically this will involve several steps of code generation. This method should return true if emission of this file type is not supported, or false on success.

Reimplemented in llvm::LLVMTargetMachine, and llvm::CPPTargetMachine.

virtual bool llvm::TargetMachine::addPassesToEmitMachineCode ( PassManagerBase &  , JITCodeEmitter &  , bool  = true  )

inlinevirtual

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.

Reimplemented in llvm::LLVMTargetMachine, and llvm::NVPTXTargetMachine.
