Detailed Description

EngineBuilder - Builder class for ExecutionEngines. Use this by stack-allocating a builder, chaining the various set* methods, and terminating it with a .create() call.

Definition at line 497 of file ExecutionEngine/ExecutionEngine.h.

Constructor & Destructor Documentation

llvm::EngineBuilder::EngineBuilder ( Module * m ) [inline]

EngineBuilder - Constructor for EngineBuilder. If create() is called and is successful, the created engine takes ownership of the module.

selectTarget - Pick a target either via -march or by guessing the native arch. Add any CPU features specified via -mcpu or -mattr.

EngineBuilder& llvm::EngineBuilder::setAllocateGVsWithCode ( bool a ) [inline]

setAllocateGVsWithCode - Sets whether global values should be allocated into the same buffer as code. For most applications this should be set to false. Allocating globals with code breaks freeMachineCodeForFunction and is probably unsafe and bad for performance. However, we have clients who depend on this behavior, so we must support it. This option defaults to false so that users of the new API can safely use the new memory manager and free machine code.

EngineBuilder& llvm::EngineBuilder::setCodeModel ( CodeModel::Model M ) [inline]

setCodeModel - Set the CodeModel that the ExecutionEngine target data is using. Defaults to target specific default "CodeModel::JITDefault".

EngineBuilder& llvm::EngineBuilder::setEngineKind ( EngineKind::Kind w ) [inline]

setEngineKind - Controls whether the user wants the interpreter, the JIT, or whichever engine works. This option defaults to EngineKind::Either.

EngineBuilder& llvm::EngineBuilder::setErrorStr ( std::string * e ) [inline]

setErrorStr - Set the error string to write to on error. This option defaults to NULL.

EngineBuilder& llvm::EngineBuilder::setJITMemoryManager ( JITMemoryManager * jmm ) [inline]

setJITMemoryManager - Sets the JIT memory manager to use. This allows clients to customize their memory allocation policies. This is only appropriate for either JIT or MCJIT; setting this and configuring the builder to create an interpreter will cause a runtime error. If create() is called and is successful, the created engine takes ownership of the memory manager. This option defaults to NULL. This option overrides setMCJITMemoryManager() as well.

EngineBuilder& llvm::EngineBuilder::setMArch ( StringRef march ) [inline]

setMArch - Override the architecture set by the Module's triple.

template<typename StringSequence >

EngineBuilder& llvm::EngineBuilder::setMAttrs ( const StringSequence & mattrs ) [inline]

setMAttrs - Set cpu-specific attributes.

References llvm::SmallVectorImpl< T >::append(), and llvm::SmallVectorImpl< T >::clear().

EngineBuilder& llvm::EngineBuilder::setMCJITMemoryManager ( RTDyldMemoryManager * mcjmm ) [inline]

setMCJITMemoryManager - Sets the MCJIT memory manager to use. This allows clients to customize their memory allocation policies for the MCJIT. This is only appropriate for the MCJIT; setting this and configuring the builder to create anything other than MCJIT will cause a runtime error. If create() is called and is successful, the created engine takes ownership of the memory manager. This option defaults to NULL. Using this option nullifies the setJITMemoryManager() option.

setMCPU - Target a specific cpu type.

EngineBuilder& llvm::EngineBuilder::setOptLevel ( CodeGenOpt::Level l ) [inline]

setOptLevel - Set the optimization level for the JIT. This option defaults to CodeGenOpt::Default.
