Detailed Description

Structure to hold a register value.

Small values (up to 64-bit integers and floating point values) use RVT_INT and RVT_FLOAT types. For bigger values the bytes() vector is used.

Public Attributes
int32	rvtype
	one of Register value types

union {
uint64 ival
	8: integer value

uint16 fval [6]
	12: floating point value in the internal representation (see ieee.h)

uchar reserve [sizeof(bytevec_t)]
	bytevec_t: custom data type (use bytes() to access it)

};

Public Member Functions
	regval_t (const regval_t &r)

regval_t &	operator= (const regval_t &r)
	Assign this regval to the given value.

void	clear (void)
	Clear register value.

bool	operator== (const regval_t &r) const
	Compare two regvals with '=='.

bool	operator!= (const regval_t &r) const
	Compare two regvals with '!='.

void	swap (regval_t &r)
	Set this = r and r = this.

void	_set_int (uint64 x)
	Use set_int()

void	_set_float (const ushort *x)
	Use set_float()

void	_set_bytes (const uchar *data, size_t size)
	Use set_bytes(const uchar *, size_t)

void	_set_bytes (const bytevec_t &v)
	Use set_bytes(const bytevec_t &)

bytevec_t &	_set_bytes (void)
	Use set_bytes(void)

Setters
These functions ensure that the previous value is cleared
void	set_int (uint64 x)
	Set int value (ival)

void	set_float (const ushort *x)
	Set float value (fval)

void	set_bytes (const uchar *data, size_t size)
	Set custom regval with raw data.

void	set_bytes (const bytevec_t &v)
	Set custom value with existing bytevec.

bytevec_t &	set_bytes (void)
	Initialize this regval to an empty custom value.

Getters
bytevec_t &	bytes (void)
	Get custom value.

const bytevec_t &	bytes (void) const
	Get const custom value.

void *	get_data (void)
	Get pointer to value.

const void *	get_data (void) const
	Get const pointer to value.

size_t	get_data_size (void) const
	Get size of value.
