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.

Definition at line 10024 of file hexrays.hpp.
◆ get_reg1()
| mreg_t lvar_locator_t::get_reg1 | ( | ) | const |
Get the register number of the variable.
Definition at line 1149 of file hexrays.hpp.
◆ get_reg2()
| mreg_t lvar_locator_t::get_reg2 | ( | ) | const |
Get the number of the second register (works only for ALOC_REG2 lvars)

◆ get_scattered() [1/2]
| scattered_aloc_t & lvar_locator_t::get_scattered | ( | ) |
Definition at line 1154 of file hexrays.hpp.
◆ get_scattered() [2/2]
| const scattered_aloc_t & lvar_locator_t::get_scattered | ( | ) | const |
Get information about scattered variable.
Definition at line 1153 of file hexrays.hpp.
◆ get_stkoff()
| sval_t lvar_locator_t::get_stkoff | ( | ) | 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)

Definition at line 1139 of file hexrays.hpp.
◆ is_reg2()
| bool lvar_locator_t::is_reg2 | ( | ) | const |
Is variable located on two registers?
Definition at line 1141 of file hexrays.hpp.
◆ is_reg_var()
| bool lvar_locator_t::is_reg_var | ( | ) | const |
Is variable located on register(s)?
Definition at line 1143 of file hexrays.hpp.
◆ is_scattered()
| bool lvar_locator_t::is_scattered | ( | ) | const |
Is variable scattered?
Definition at line 1147 of file hexrays.hpp.
◆ is_stk_var()
| bool lvar_locator_t::is_stk_var | ( | ) | const |
Is variable located on the stack?
Definition at line 1145 of file hexrays.hpp.
Member Data Documentation
◆ 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.
- Examples
- hexrays_sample4.cpp.
Definition at line 1123 of file hexrays.hpp.
◆ location
| vdloc_t lvar_locator_t::location |
Variable location.
- Examples
- hexrays_sample4.cpp.
Definition at line 1122 of file hexrays.hpp.
