Detailed Description

Local variable locator.

Local variables are located using definition ea and location. Each variable must have a unique locator, this is how we tell them apart.

Member Function Documentation

get_stkoff()

sval_t lvar_locator_t::get_stkoff ( ) const

inline

Get offset of the varialbe in the stack frame.

Returns

a non-negative value for stack variables. The value is an offset from the bottom of the stack frame in terms of vd-offsets. negative values mean error (not a stack variable)

is_reg1()

bool lvar_locator_t::is_reg1 ( ) const

inline

Is variable located on one register?

is_reg2()

bool lvar_locator_t::is_reg2 ( ) const

inline

Is variable located on two registers?

is_reg_var()

bool lvar_locator_t::is_reg_var ( ) const

inline

Is variable located on register(s)?

is_stk_var()

bool lvar_locator_t::is_stk_var ( ) const

inline

Is variable located on the stack?

is_scattered()

bool lvar_locator_t::is_scattered ( ) const

inline

Is variable scattered?

get_reg1()

mreg_t lvar_locator_t::get_reg1 ( ) const

inline

Get the register number of the variable.

get_reg2()

mreg_t lvar_locator_t::get_reg2 ( ) const

inline

Get the number of the second register (works only for ALOC_REG2 lvars)

get_scattered() [1/2]

const scattered_aloc_t & lvar_locator_t::get_scattered ( ) const

inline

Get information about scattered variable.

get_scattered() [2/2]

scattered_aloc_t & lvar_locator_t::get_scattered ( )

Member Data Documentation

location

vdloc_t lvar_locator_t::location

Variable location.

defea

ea_t lvar_locator_t::defea = BADADDR

Definition address.

Usually, this is the address of the instruction that initializes the variable. In some cases it can be a fictional address.
