addPassesToEmitFile()

virtual bool llvm::TargetMachine::addPassesToEmitFile ( PassManagerBase &  , raw_pwrite_stream &  , raw_pwrite_stream *  , CodeGenFileType  , bool  = true, MachineModuleInfo *  MMI = nullptr  )

inlinevirtual

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. MMI is an optional parameter that, if set to non-nullptr, will be used to set the MachineModuloInfo for this PM.

addPassesToEmitMC()

virtual bool llvm::TargetMachine::addPassesToEmitMC ( PassManagerBase &  , MCContext *&  , raw_pwrite_stream &  , bool  = true  )

This method returns true if machine code is not supported. It fills the MCContext Ctx pointer which can be used to build custom MCStreamer.

DataLayout for the target: keep ABI type size and alignment.

The DataLayout is created based on the string representation provided during construction. It is kept here only to avoid reparsing the string but should not really be used during compilation, because it has an internal cache that is context specific.
