Member Function Documentation

void * PPCJITInfo::emitFunctionStub	(	const Function *	F,
		void *	Fn,
		MachineCodeEmitter &	MCE
	)			`[virtual]`

emitFunctionStub - Use the specified MachineCodeEmitter object to emit a small native function that simply calls the function at the specified address. Return the address of the resultant function.

Reimplemented from llvm::TargetJITInfo.

Definition at line 332 of file PPCJITInfo.cpp.

void PPCJITInfo::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 381 of file PPCJITInfo.cpp.

References llvm::MachineRelocation::getConstantVal(), llvm::MachineRelocation::getMachineCodeOffset(), llvm::MachineRelocation::getRelocationType(), llvm::MachineRelocation::getResultPointer(), llvm::PPC::reloc_absolute_high, llvm::PPC::reloc_absolute_low, llvm::PPC::reloc_absolute_low_ix, llvm::PPC::reloc_pcrel_bcx, and llvm::PPC::reloc_pcrel_bx.

void PPCJITInfo::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.
