virtual bool llvm::LLVMTargetMachine::addAssemblyEmitter (  PassManagerBase &  ,
bool  ,
raw_ostream & 
)  [inline, virtual]
 

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.

Reimplemented in llvm::AlphaTargetMachine, llvm::ARMTargetMachine, llvm::SPUTargetMachine, llvm::IA64TargetMachine, llvm::MipsTargetMachine, llvm::PIC16TargetMachine, llvm::PPCTargetMachine, llvm::SparcTargetMachine, and llvm::X86TargetMachine.

virtual bool llvm::LLVMTargetMachine::addCodeEmitter (  PassManagerBase &  ,
bool  ,
bool  ,
MachineCodeEmitter & 
)  [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. If DumpAsm is true, the generated assembly is printed to cerr.

Reimplemented in llvm::AlphaTargetMachine, llvm::ARMTargetMachine, llvm::PPCTargetMachine, and llvm::X86TargetMachine.

virtual bool llvm::LLVMTargetMachine::addInstSelector (  PassManagerBase &  ,
bool 
)  [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.

Reimplemented in llvm::AlphaTargetMachine, llvm::ARMTargetMachine, llvm::SPUTargetMachine, llvm::IA64TargetMachine, llvm::MipsTargetMachine, llvm::PIC16TargetMachine, llvm::PPCTargetMachine, llvm::SparcTargetMachine, and llvm::X86TargetMachine.

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.

Reimplemented from llvm::TargetMachine.

bool LLVMTargetMachine::addPassesToEmitFileFinish (  PassManagerBase &  PM,
MachineCodeEmitter *  MCE,
bool  Fast
)  [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.

Reimplemented from llvm::TargetMachine.

bool LLVMTargetMachine::addPassesToEmitMachineCode (  PassManagerBase &  PM,
MachineCodeEmitter &  MCE,
bool  Fast
)  [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::addPostRegAlloc (  PassManagerBase &  ,
bool 
)  [inline, virtual]
 

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.

Reimplemented in llvm::X86TargetMachine.

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

addPreEmitPass - This pass may be implemented by targets that want to run passes immediately before machine code is emitted. This should return true if -print-machineinstrs should print out the code after the passes.

Reimplemented in llvm::AlphaTargetMachine, llvm::ARMTargetMachine, llvm::IA64TargetMachine, llvm::MipsTargetMachine, llvm::PIC16TargetMachine, llvm::PPCTargetMachine, and llvm::SparcTargetMachine.

addSimpleCodeEmitter - This pass should be overridden by the target to add a code emitter (without setting flags), if supported. If this is not supported, 'true' should be returned. If DumpAsm is true, the generated assembly is printed to cerr.
