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

dstr()

const char * lvar_locator_t::dstr

(

void

)

const

Definition at line 9971 of file hexrays.hpp.

get_reg1()

mreg_t lvar_locator_t::get_reg1

(

void

)

const

Get the register number of the variable.

Definition at line 1158 of file hexrays.hpp.

get_reg2()

mreg_t lvar_locator_t::get_reg2

(

void

)

const

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

Definition at line 1160 of file hexrays.hpp.

get_scattered() [1/2]

scattered_aloc_t & lvar_locator_t::get_scattered

(

void

)

Definition at line 1163 of file hexrays.hpp.

get_scattered() [2/2]

const scattered_aloc_t & lvar_locator_t::get_scattered

(

void

)

const

Get information about scattered variable.

Definition at line 1162 of file hexrays.hpp.

get_stkoff()

sval_t lvar_locator_t::get_stkoff

(

void

)

const

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

(

void

)

const

Is variable located on one register?

Definition at line 1148 of file hexrays.hpp.

is_reg2()

bool lvar_locator_t::is_reg2

(

void

)

const

Is variable located on two registers?

Definition at line 1150 of file hexrays.hpp.

is_reg_var()

bool lvar_locator_t::is_reg_var

(

void

)

const

Is variable located on register(s)?

Definition at line 1152 of file hexrays.hpp.

is_scattered()

bool lvar_locator_t::is_scattered

(

void

)

const

Is variable scattered?

Definition at line 1156 of file hexrays.hpp.

is_stk_var()

bool lvar_locator_t::is_stk_var

(

void

)

const

Is variable located on the stack?

Definition at line 1154 of file hexrays.hpp.

Member Data Documentation

defea

ea_t lvar_locator_t::defea

Definition address.

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

Examples

hexrays_sample4.cpp.

Definition at line 1132 of file hexrays.hpp.

location

vdloc_t lvar_locator_t::location

Variable location.

Examples

hexrays_sample4.cpp.

Definition at line 1131 of file hexrays.hpp.
