Member Function Documentation

char * X86JITInfo::allocateThreadLocalMemory ( size_t size )

virtual

allocateThreadLocalMemory - Each target has its own way of handling thread local variables. This method returns a value only meaningful to the target.

Reimplemented from llvm::TargetJITInfo.

Definition at line 575 of file X86JITInfo.cpp.

References llvm_unreachable.

void * X86JITInfo::emitFunctionStub	(	const Function *	F,
		void *	Target,
		JITCodeEmitter &	JCE
	)

virtual

emitFunctionStub - Use the specified JITCodeEmitter object to emit a small native function that simply calls the function at the specified address.

Reimplemented from llvm::TargetJITInfo.

Definition at line 471 of file X86JITInfo.cpp.

References llvm::JITCodeEmitter::emitAlignment(), llvm::JITCodeEmitter::emitByte(), llvm::JITCodeEmitter::emitWordLE(), llvm::JITCodeEmitter::getCurrentPCValue(), and X86CompilationCallback().

void * X86JITInfo::emitGlobalValueIndirectSym	(	const GlobalValue *	GV,
		void *	ptr,
		JITCodeEmitter &	JCE
	)

virtual

emitGlobalValueIndirectSym - Use the specified JITCodeEmitter object to emit an indirect symbol which contains the address of the specified ptr.

Reimplemented from llvm::TargetJITInfo.

Definition at line 443 of file X86JITInfo.cpp.

References llvm::JITCodeEmitter::allocIndirectGV(), and llvm::MachineCodeEmitter::emitWordLEInto().

TargetJITInfo::LazyResolverFn X86JITInfo::getLazyResolverFunction ( JITCompilerFn F )

virtual

getLazyResolverFunction - Expose the lazy resolver to the JIT.

Reimplemented from llvm::TargetJITInfo.

Definition at line 424 of file X86JITInfo.cpp.

References F(), llvm::X86Subtarget::hasSSE1(), JITCompilerFunction, TsanIgnoreWritesBegin, TsanIgnoreWritesEnd, and X86CompilationCallback().

uintptr_t llvm::X86JITInfo::getPICBase ( ) const

inline

Definition at line 77 of file X86JITInfo.h.

uintptr_t X86JITInfo::getPICJumpTableEntry	(	uintptr_t	BB,
		uintptr_t	Entry
	)

virtual

getPICJumpTableEntry - Returns the value of the jumptable entry for the specific basic block.

Reimplemented from llvm::TargetJITInfo.

Definition at line 522 of file X86JITInfo.cpp.

TargetJITInfo::StubLayout X86JITInfo::getStubLayout ( )

virtual

Returns the maximum size and alignment for a call stub on this target.

Reimplemented from llvm::TargetJITInfo.

Definition at line 460 of file X86JITInfo.cpp.

void X86JITInfo::relocate	(	void *	Function,
		MachineRelocation *	MR,
		unsigned	NumRelocs,
		unsigned char *	GOTBase
	)

virtual

relocate - Before the JIT can run a block of code that has been emitted, it must rewrite the code to contain the actual addresses of any referenced global symbols.

Reimplemented from llvm::TargetJITInfo.

Definition at line 542 of file X86JITInfo.cpp.

References llvm::MachineRelocation::getConstantVal(), llvm::MachineRelocation::getMachineCodeOffset(), llvm::MachineRelocation::getRelocationType(), llvm::MachineRelocation::getResultPointer(), llvm::X86::reloc_absolute_dword, llvm::X86::reloc_absolute_word, llvm::X86::reloc_absolute_word_sext, llvm::X86::reloc_pcrel_word, and llvm::X86::reloc_picrel_word.

void X86JITInfo::replaceMachineCodeForFunction	(	void *	Old,
		void *	New
	)

virtual

replaceMachineCodeForFunction - Make it so that calling the function whose machine code is at OLD turns into a call to NEW, perhaps by overwriting OLD with a branch to NEW. This is used for self-modifying code.

Implements llvm::TargetJITInfo.

Definition at line 34 of file X86JITInfo.cpp.

References llvm::sys::ValgrindDiscardTranslations().

void llvm::X86JITInfo::setPICBase ( uintptr_t Base )

inline

setPICBase / getPICBase - Getter / setter of PICBase, used to compute PIC jumptable entry.
