Detailed Description

Disassembler for the ARM architecture.

Most of the useful disassembly methods can be found in the superclass.

Member Function Documentation

virtual Disassembler* DisassemblerArm::clone

(

)

const [inline, virtual]

Creates a new copy of a disassembler.

The new copy has all the same settings as the original.

Thread safety: The thread safety of this virtual method depends on the implementation in the subclass.

Implements Disassembler.

bool DisassemblerArm::can_disassemble

(

SgAsmGenericHeader *

)

const [virtual]

See Disassembler::can_disassemble.

Implements Disassembler.

SgAsmInstruction * DisassemblerArm::disassembleOne	(	const MemoryMap *	map,
		rose_addr_t	start_va,
		AddressSet *	successors = NULL
	)			[virtual]

See Disassembler::disassembleOne.

Implements Disassembler.

virtual void DisassemblerArm::assembleOne	(	SgAsmInstruction *	,
		SgUnsignedCharList &
	)			[inline, virtual]

See Disassembler::assembleOne.

SgAsmInstruction * DisassemblerArm::make_unknown_instruction

(

const Exception &

)

[virtual]

See Disassembler::can_disassemble.

SgAsmArmInstruction * DisassemblerArm::makeInstructionWithoutOperands	(	uint32_t	address,
		const std::string &	mnemonic,
		int	condPos,
		ArmInstructionKind	kind,
		ArmInstructionCondition	cond,
		uint32_t	insn
	)			[static, private]

SgAsmArmRegisterReferenceExpression * DisassemblerArm::makeRegister

(

uint8_t

reg

)

const [private]

Creates a general-purpose register reference expression.

SgAsmArmRegisterReferenceExpression * DisassemblerArm::makePsrFields	(	bool	useSPSR,
		uint8_t	fields
	)			const [private]

Create a reference to one of the program status registers.

If useSPSR is true then create a reference to the saved program status register, otherwise create a reference to the current program status register. The fields is a 4-bit mask indicating which individual fields of the register are selected.

The field bits are 0x01 => c control field mask bit 0x02 => x extension field mask bit 0x04 => s status field mask bit 0x08 => f flags field mask bit

Called by constructor.

void DisassemblerArm::startInstruction	(	rose_addr_t	start_va,
